Definitions

the present invention relates to a so-called projector type vehicle illumination lamp, and more particularly to a vehicle illumination lamp which is designed to form a variable luminous intensity distribution pattern.
a projector type vehicle illumination lamp In general, in a projector type vehicle illumination lamp, light from a light source which is disposed further rearwards than a rear focal point of a projection lens is designed to be reflected towards the projection lens by a reflector.
JP-A-2011-65960 describes a projector type vehicle illumination lamp which is designed to form a high-beam variable luminous intensity distribution pattern.
a movable shade is disposed between the reflector and the projection lens.
This movable shade is designed to shift between a light interruptive position where part of reflected light from the reflector is interrupted and a light uninterruptive position where the part of the reflected light becomes free from interruption or is left uninterrupted. Then, when this movable shade shifts to the light uninterruptive position, a high-beam luminous intensity distribution pattern is formed as a first variable luminous intensity distribution pattern, whereas when the movable shade shifts to the light interruptive position, a luminous intensity distribution pattern in which part of the high-beam luminous intensity distribution pattern is lost is formed as a second variable luminous intensity distribution pattern.
the forward visibility of the driver of the subject vehicle can be enhanced without dazzling the driver of a preceding vehicle or an oncoming vehicle.
a luminous intensity distribution pattern that is formed by the reflected light from the second reflector is formed into a constant pattern irrespective of the position of the movable shade. Therefore, when the movable shade shifts to the light interruptive position to form the second variable luminous intensity distribution pattern, part of the luminous intensity distribution pattern formed by the reflected light from the second reflector projects to a dark portion which is formed in the second variable luminous intensity distribution pattern when it is formed as a result of the part of the high-beam luminous intensity distribution pattern being lost. This causes a problem that the driver of a preceding vehicle or an oncoming vehicle is dazzled by the resulting luminous intensity distribution pattern.
the invention has been made in view of these situations, and an object thereof is to provide a projector type vehicle illumination lamp designed to form a high-beam variable luminous intensity distribution pattern in which when a second variable luminous intensity distribution pattern is formed which lacks part of a high-beam luminous intensity distribution pattern as a first variable luminous intensity distribution pattern, the brightness of the first variable luminous intensity distribution pattern can be enhanced without dazzling the driver of a preceding vehicle or an oncoming vehicle.
this object is attained by adopting a configuration in which a second light source and a second reflector are additionally provided and then devising an optimum relationship between them.
a vehicle illumination lamp designed to form a high-beam variable luminous intensity distribution pattern
the vehicle illumination lamp comprising a projection lens, a light source which is disposed further rearwards than a rear focal point of the projection lens, a reflector which reflects light from the light source towards the projection lens, and a movable shade which is disposed between the reflector and the projection lens so as to shift between a light interruptive position where part of reflected light from the reflector is interrupted so as to eliminate part of a high-beam luminous intensity distribution pattern and a light uninterruptive position where the interruption of the reflected light is released, wherein a second light source is disposed rearwards of the movable shade and a second reflector is disposed forwards of the movable shade, and wherein the second light source and the second reflector are disposed in such a positional relationship that when the movable shade shifts to the light uninterruptive position, light from the second light source is reflected by the second reflector so as
the type of the "light source” is not limited to any specific type, and hence, for example, a light emitting portion of a discharge bulb, a filament of a halogen lamp or a light emitting chip of a light emitting element such as a light emitting diode can be adopted.
the disposition of the "second light source” and the “second reflector” is not limited to any specific disposition as long as the second light source and the second reflector are disposed in such a positional relationship that when the movable shade shifts to the light uninterruptive position, light from the second light source is reflected by the second reflector so as to be shone to the front of the lamp without being allowed to be incident on the projection lens, while when the movable shade shifts to the light interruptive position, the light from the second light source is interrupted by the movable shade so as not to be incident on the second reflector.
the vehicle illumination lamp according to the present invention configured as a projector type vehicle illumination lamp designed to form the high-beam variable luminous intensity distribution pattern
the movable shade designed to selectively form the high-beam luminous intensity distribution pattern which is the first variable luminous intensity distribution pattern and the second variable luminous intensity distribution pattern in which part of the first variable luminous intensity distribution pattern is eliminated
the second light source is disposed rearwards of the movable shade
the second reflector is disposed forwards of the movable shade.
the second light source and the second reflector are disposed in such a positional relationship that when the movable shade shifts to the light uninterruptive position, light from the second light source is reflected by the second reflector so as to be shone to the front of the lamp without being allowed to be incident on the projection lens, while when the movable shade shifts to the light interruptive position, the light from the second light source is interrupted by the movable shade so as not to be incident on the second reflector.
the first variable luminous intensity distribution pattern is formed when the movable shade shifts to the light uninterruptive position, and as this occurs, the light from the second light source is reflected by the second reflector and is thereafter shone to the front of the lamp without being allowed to be incident on the projection lens. Therefore, the brightness of the first variable luminous intensity distribution pattern can be enhanced by a luminous intensity distribution pattern which is formed by the light shone to the front of the lamp.
the second variable luminous intensity distribution pattern in which part of the first variable luminous intensity distribution pattern is eliminated is formed when the movable shade shifts to the light interruptive position.
the light from the second light source is interrupted by the movable shade and is not allowed to be incident on the second reflector. Therefore, it becomes possible to prevent part of the luminous intensity distribution pattern which is formed by the reflected light from the second reflector from being formed so as to project to a dark portion in the second variable luminous intensity distribution pattern which is formed as a result of the part of the first movable luminous intensity distribution pattern being eliminated.
the brightness of the first variable luminous intensity distribution pattern can be enhanced without dazzling the driver of a preceding or oncoming vehicle.
the brightness of the high-beam variable luminous intensity distribution pattern can be enhanced further by a luminous intensity distribution pattern which is formed by the reflected light from the third reflector.
the vehicle illumination lamp can be switched between a low beam and a high beam.
the movable shade and the second movable shade can be disposed without any difficulty.
the second light source is made up of a light emitting element which is disposed to be oriented upwards on or near to an optical axis of the projection lens
the second light source is made up of a light emitting element which is disposed to be oriented downwards in a position lying further forwards than the light source and further upwards than the optical axis
the second reflector is disposed further downwards than the optical axis
the light source, the second light source and the second reflector can be disposed compact.
Fig. 1 is a front view of a vehicle illumination lamp 10 according to an embodiment of the invention, which shows a state in which a movable shade 18 is in a light uninterruptive position and a second movable shade 28 is in a light interruptive position.
Fig. 2 is a sectional view of the vehicle illumination lamp 10 which is taken along the line II-II in Fig. 1 .
the vehicle illumination lamp 10 is configured as a projector type lamp unit and is designed to be incorporated in a lamp body, not shown, for use.
This vehicle illumination lamp 10 is designed to form a high-beam variable luminous intensity distribution pattern.
the vehicle illumination lamp 10 includes a projection lens 12, a light source 14 which is disposed further rearwards than a rear focal point F of the projection lens 12, a reflector 16 which reflects light from the light source 14 towards the projection lens 12, a movable shade 18 which is disposed between the reflector 16 and the projection lens 12, and a holder 40 which supports these constituent components of the vehicle illumination lamp 10.
the projection lens 12 is a planoconvex aspheric lens which is convex on a front surface and is flat on a rear surface thereof. This projection lens 12 is supported on the holder 40 via a lens holder 20.
the light source 14 is made up of a light emitting element which is disposed to be oriented upwards on an optical axis Ax of the projection lens 12. Specifically, the light source 14 is made up of a white light emitting diode having a horizontally elongated rectangular light emitting chip.
the reflector 16 is disposed so as to cover the light source 14 from thereabove.
a reflecting surface 16a of the reflector 16 is formed into a substantially ellipsoidal curved surface which has a major axis which is coaxial with the optical axis Ax and whose first focal point is constituted by a light emitting center of the light source 14.
a lower edge of the reflecting surface 16 is situated on a horizontal plane which contains the optical axis Ax.
This reflecting surface 16a is designed to reflect light from the light source 14 in such a form that the light substantially converges near to the front of the rear focal point F in a vertical plane and that the converging position is displaced forwards in a horizontal plane.
the movable shade 18 is disposed near to the front of the rear focal point F of the projection lens 12 and is designed to shift between a light interruptive position (a position indicated by chain double-dashed lines in Fig. 1 ) where part of reflected light from the reflector 16 is interrupted and a light uninterruptive position (a position indicated by solid lines in Fig. 1 ) where the interruption of the reflected light is released.
This movable shade 18 is a plate-shaped member which is disposed so as to lie along a vertical plane which intersects the optical axis Ax at right angles.
the movable shade 18 is supported on an actuator 42 at a right end portion (a left end portion when the lamp is seen from the front, this being true in the following diagrams) thereof so as to rotate about an axis Ax1 which extends in a front-to-rear direction of the actuator 42. Then, the movable shade 18 is designed to shift between the light interruptive position and the light uninterruptive position when the actuator 42 is driven.
the movable shade 18 When shifting to the light interruptive position, the movable shade 18 is disposed so that an upper edge 18a extends horizontally near to a lower side of the optical axis Ax, while a left edge 18b extends along a vertical plane which contains the optical axis Ax.
a high-beam variable luminous intensity distribution pattern is formed as a first variable luminous intensity distribution pattern PH1 (refer to Fig. 7(a) ), while when the movable shade 18 shifts to the light interruptive position, a luminous intensity distribution pattern in which part of the high-beam luminous intensity distribution pattern is eliminated is formed as a second variable luminous intensity distribution pattern PH2 (refer to Fig. 7(b) ).
a second light source 24 is disposed rearwards of the movable shade 18, and a second reflector 26 is disposed forwards of the movable shade 18.
Fig. 3 is a sectional view of the vehicle illumination lamp 10, which is similar to Fig. 2 , showing a state in which the second movable shade 28 is caused to shift from the state shown in Fig. 2 to a light uninterruptive position.
Fig. 4 is a perspective view of the vehicle illumination lamp 10 which is in the state shown in Fig. 3 with main constituent elements removed.
Fig. 5 is a sectional view of the vehicle illumination lamp 10, which is similar to Fig. 3 , showing a state in which the movable shade 18 is caused to shift from the state shown in Fig. 3 to the light interruptive position.
Fig. 6 is a perspective view of the vehicle illumination lamp 10 which is in the state shown in Fig. 5 with the main constituent elements removed.
the second light source 24 and the second reflector 26 are disposed in such a positional relationship that when the movable shade 18 shifts to the light uninterruptive position, light from the second light source 24 is reflected by the second reflector 26 so as to be shone to the front of the lamp without being allowed to be incident on the projection lens 12, while when the movable shade 18 shifts to the light interruptive position, the light from the second light source 24 is interrupted by the movable shade 18 so as not to be incident on the second reflector 26.
the second light source 24 is made up of a light emitting element which is disposed to be oriented downwards in a position which lies further forwards than the light source 14 and further upwards than the optical axis Ax.
this light source 24 is made up of a white light emitting diode having a horizontally elongated rectangular light emitting chip.
the second reflector 26 is disposed further downwards than the optical axis Ax of the projection lens 12. Specifically, this second reflector 26 is disposed downwardly rightwards of the projection lens 12.
a reflecting surface 26a of the second reflector 26 is formed into a paraboloidal surface whose focal point is constituted by the second light source 24 as a reference plane. The reflecting surface 26a is designed to reflect light from the second light source 24 as light which slightly diffuses.
a third reflector 36 is disposed rearwards of the movable shade 18, and this third reflector 36 is designed to reflect light from the second light source 24 towards the projection lens 12.
This third reflector 36 is disposed so as to cover the second light source 24 from therebelow.
a reflecting surface 36a of this third reflector 36 is formed into a substantially ellipsoidal curved surface which has a major axis which is coaxial with the optical axis Ax and whose first focal point is constituted by a light emitting center of the second light source 24.
An upper edge of the reflecting surface 36a is situated on the horizontal plane which contains the optical axis Ax.
this reflecting surface 36a is designed to reflect light from the second light source 24 in such a form that the light substantially converges in a position lying obliquely upwards and forwards of the rear focal point F in a vertical plane and that the converging position is displaced forwards in a horizontal plane.
the vehicle illumination lamp 10 is designed not only to form the high-beam variable luminous intensity distribution pattern but also to form selectively a low-beam luminous intensity distribution pattern.
the second movable shade 28 is disposed between the reflector 16 and the projection lens 12.
the second movable shade 28 is disposed near to the rear of the movable shade 18 so as to shift between a light interruptive position (a position indicated by solid lines in Fig. 1 ) where part of reflected light from the reflector 16 is interrupted and a light uninterruptive position (a position indicated by chain double-dashed lines in Fig. 1 ) where the interruption of the reflected light is released.
This second movable shade 28 is a plate-shaped member which is disposed so as to lie along a vertical plane which intersects the optical axis Ax at right angles.
the second movable shade 28 is rotatably supported on an actuator 44 at a left end portion thereof. Then, the second movable shade 28 is designed to shift between the light interruptive position and the light uninterruptive position when the actuator 44 is driven.
the second movable shade 28 When shifting to the light interruptive position, the second movable shade 28 is disposed so that an upper edge 28a extends horizontally in a step-like fashion so as to pass through the rear focal point F of the projection lens 12.
this vehicle illumination lamp 10 is switched to the low beam, only the light source 14 is turned on with the second movable shade 28 caused to shift to the light interruptive position, whereby a low-beam luminous intensity distribution pattern PL (refer to Fig. 8(a) ) is formed.
the second light source 24 is additionally turned on with the second movable shade 28 caused to shift to the light uninterruptive position, whereby the high-beam luminous intensity distribution patterns PH1, PH2 (refer to Figs. 7(a), (b) ) are formed.
the second light source 24 and the second reflector 26 are in such a positional relationship that light from the second light source 24 passes above the second movable shade 28 which has shifted to the light uninterruptive position to reach the second reflector 26.
the second light source 24, the second and third reflectors 26, 36, the second movable shade 28 and the actuators 42, 44 are also supported on the holder 40.
Fig. 7 shows diagrams depicting in a perspective fashion the variable luminous intensity distribution patterns which are formed on an imaginary vertical aiming board which is disposed 25 m ahead of the vehicle illumination lamp 10, of which Fig. 7(a) shows the first variable luminous intensity distribution pattern and Fig. 7(b) shows the second variable luminous intensity distribution pattern.
the first variable luminous intensity distribution pattern PH1 shown in Fig. 7(a) is the high-beam luminous intensity distribution pattern and is formed when the light source 14 and the second light source 24 are tuned on simultaneously with both the movable shade 18 and the second movable shade 28 having shifted to the light uninterruptive positions.
This first variable luminous intensity distribution pattern PH1 is formed as a composite luminous intensity distribution pattern in which three luminous intensity distribution patterns P1A, P2, P3 are superposed one on another.
the luminous intensity distribution pattern P1A is a luminous intensity distribution pattern which forms a basic configuration of the first variable luminous intensity distribution pattern PH1.
the luminous intensity distribution pattern P1A is a luminous intensity distribution pattern which is formed by light which is emitted from the light source 14, is then reflected on the reflector 16 and is thereafter shone to the front of the lamp through the projection lens 12.
the luminous intensity distribution pattern P2 is a relatively small luminous intensity distribution pattern which enhances a central luminous intensity of the first variable luminous intensity distribution pattern PH1 so as to ensure a sufficient far-field visibility.
This luminous intensity distribution pattern P2 is a luminous intensity distribution pattern which is formed by light which is emitted from the second light source 24, is then reflected on the second reflector 26 and is thereafter shone to the front of the lamp without being allowed to be incident on the projection lens 12.
a luminous intensity distribution pattern P3A is a luminous intensity distribution pattern which enhances the overall brightness of the first variable luminous intensity distribution pattern PH1.
This luminous intensity distribution pattern P3A is a luminous intensity distribution pattern which is formed by light which is emitted from the second light source 24, is then reflected on the third reflector 36 and is thereafter shone to the front of the lamp through the projection lens 12.
the second variable luminous intensity distribution pattern PH2 shown in Fig 7(b) is a luminous intensity distribution pattern in which part of the high-beam luminous intensity distribution pattern is eliminated and is formed when the light source 14 and the second light source 24 are turned on simultaneously with the second movable shade 28 and the movable shade 18 having shifted to the light uninterruptive position and the light interruptive position, respectively.
a horizontal cut-off line CL3 and a vertical cut-off line CL4 are formed, respectively, by the upper edge 18a and the left edge 18b of the movable shade 18 which is in the light interruptive position to thereby form a luminous intensity distribution pattern in which a dark portion is formed at an upper right-hand side portion as a result of a corresponding portion of the first variable luminous intensity distribution pattern PH1 being eliminated.
This second variable luminous intensity distribution pattern PH2 is formed as a composite luminous intensity distribution pattern in which two luminous intensity distribution patterns P1 B, P3B are superposed one on the other.
the luminous intensity distribution pattern PB1 is a luminous intensity distribution pattern which forms a basic configuration of the second variable luminous intensity distribution pattern PH2.
This luminous intensity distribution pattern PB1 is a luminous intensity distribution pattern which is formed by light which is emitted from the light source 14, is then reflected on the reflector 16 and is thereafter shone to the front of the lamp through the projection lens 12.
This luminous intensity distribution pattern P1B has the horizontal cut-off line CL3 and the vertical cut-off line CL4.
the luminous intensity distribution pattern P3B is a luminous intensity distribution pattern which enhances the overall brightness of the second variable luminous intensity distribution pattern PH2.
This luminous intensity distribution pattern PH2 is a luminous intensity distribution pattern which is formed by light which is emitted from the second light source 24, is then reflected on the third reflector 36 and is thereafter shone to the front of the lamp through the projection lens 12.
This luminous intensity distribution pattern P3B also has the horizontal cut-off line CL3 and the vertical cut-off line CL4.
the luminous intensity distribution pattern P2 which contributes to the formation of the first variable luminous intensity distribution pattern PH1 does not contribute to the formation of the second variable luminous intensity distribution pattern PH2. This is because the light from the second light source 24 is interrupted by the movable shade 18 which is in the light interruptive position so as not to be incident on the second reflector 26.
the low-beam luminous intensity distribution pattern PL is formed as a luminous intensity distribution pattern in which an upper portion of the luminous intensity distribution pattern P1A (refer to Fig. 8(b) ) which forms the basic configuration of the first variable luminous intensity distribution pattern PH1 is eliminated.
This low-beam luminous intensity distribution pattern PL is a low-beam luminous intensity distribution pattern which is suitable for a left-hand traffic.
Left and right horizontal cut-off lines CL1, CL2 are formed at an upper end portion thereof, and these left and right horizontal cut-off lines CL1, CL2 are different in level and are connected together via an elbow point E.
These left and right cut-off lines CL1, CL2 which are different in level are formed by the upper edge 28a of the second movable shade 28 which has shifted to the light interruptive position.
the vehicle illumination lamp 10 is configured as the projector type vehicle illumination lamp which forms the high-beam variable luminous intensity distribution pattern.
the second light source 24 is disposed rearwards of the movable shade 18 which forms selectively the high-beam luminous intensity distribution pattern as the first variable luminous intensity distribution pattern PH1 and the second variable luminous intensity distribution pattern PH2 in which the part of the first variable luminous intensity distribution pattern is eliminated, and the second reflector 26 is disposed forwards of the movable shade 18.
these second light source 24 and the second reflector 26 are in such a positional relationship that when the movable shade 18 shifts to the light uninterruptive position, the light from the second light source 24 is reflected by the second reflector 26 so as to be shone to the front of the lamp without being allowed to be incident on the projection lens 12, while when the movable shade 18 shifts to the light interruptive position, the light from the second light source 24 is interrupted by the movable shade 18 so as not to be incident on the second reflector 26.
the first variable luminous intensity distribution pattern PH1 is formed when the movable shade 18 shifts to the light uninterruptive position, and as this occurs, the light from the second light source 24 is reflected by the second reflector 26 and is thereafter shone to the front of the lamp without being allowed to be incident on the projection lens 12. Therefore, the brightness of the first variable luminous intensity distribution pattern PH1 can be enhanced by a luminous intensity distribution pattern P2 which is formed by the light so shone to the front of the lamp.
the second variable luminous intensity distribution pattern in which the part of the first variable luminous intensity distribution pattern PH1 is eliminated is formed when the movable shade 18 shifts to the light interruptive position.
the light from the second light source 24 is interrupted by the movable shade 18 and is not allowed to be incident on the second reflector 26. Therefore, it becomes possible to prevent part of the luminous intensity distribution pattern P2 which is formed by the reflected light from the second reflector 26 from being formed so as to project to the upper right-hand side dark portion in the second variable luminous intensity distribution pattern which is formed as a result of the part of the first movable luminous intensity distribution pattern PH1 being eliminated. By so doing, it becomes possible to prevent the driver of the oncoming vehicle 2 from being dazzled.
the brightness of the first variable luminous intensity distribution pattern PH1 can be enhanced without dazzling the driver of the oncoming vehicle 2.
the third reflector 36 is disposed rearwards of the movable shade 18 which third reflector 36 is designed to reflect light from the second light source 24 towards the projection lens 12, and therefore, the brightness of the high-beam variable luminous intensity distribution patterns PH1, PH2 can be enhanced further by the luminous intensity distribution patterns P3A, P3B which are formed by the reflected light from that third reflector 36.
the second movable shade 28 is disposed between the reflector 16 and the projection lens 12 which second movable shade 28 is designed to shift between the light interruptive position where part of the reflected light from the reflector 16 is interrupted so as to form the low-beam luminous intensity distribution pattern PL and the light uninterruptive position where the interruption of the reflected light is released, and therefore, the vehicle illumination lamp 10 can be switched between the low beam and the high beam.
the second light source 24 and the second reflector 26 are disposed in such a positional relationship that the light from the second light source 24 reaches the second reflector 26 by passing above the second movable shade 28 which has shifted to the light uninterruptive position, and therefore, the movable shade 18 and the second movable shade 28 can be disposed without any difficulty.
the light source 14 is made up of the light emitting element which is disposed to be oriented upwards on the optical axis Ax of the projection lens 12
the second light source 24 is made up of the light emitting element which is disposed to be oriented downwards in the position lying further forwards than the light source 14 and further upwards than the optical axis Ax
the second reflector 26 is disposed further downwards than the optical axis Ax. Therefore, the light source 14, the second light source 24 and the second reflector 26 can be disposed compact.
the luminous intensity distribution pattern P2 which is formed by the light which is emitted from the second light source 24, is then reflected by the second reflector 26 and is thereafter shone to the front of the lamp without being allowed to be incident on the projection lens 12 is described as being formed as the relatively small luminous intensity distribution pattern which enhances the central luminous intensity of the first variable luminous intensity distribution pattern PH1 so as to ensure the sufficient far-field visibility.
the luminous intensity distribution pattern P2 can also be formed as a relatively large luminous intensity distribution pattern.
the second variable luminous intensity distribution pattern PH2 is described as being formed as the luminous intensity distribution pattern in which the upper right-hand side portion becomes the dark portion relative to the first variable luminous intensity distribution pattern PH1.
the second variable luminous intensity distribution pattern can be formed as a luminous intensity distribution pattern in which an upper left-hand side portion becomes a dark portion relative to the first variable luminous intensity distribution pattern PH1. Then, by adopting this configuration, the dazzling of the driver of a preceding vehicle can be prevented when the second variable luminous intensity distribution pattern is formed.
the vehicle illumination lamp 10 is described as being designed to form the low-beam luminous intensity distribution pattern suitable for the left-hand traffic as the low-beam luminous intensity distribution pattern PL.
the same function and advantage as those of the embodiment can be obtained by adopting the same configuration as that of the embodiment.
