Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lamp mounted on a corner of a vehicle, in which a front side opening of a lamp body wraps around the side of the vehicle to reflect a light source from the vehicle side. The present invention relates to a vehicular lamp in which a step between a plurality of reflecting surfaces forming a reflector is provided up to a side edge portion on one side.

[Problems to be Solved by Prior Art and Invention]

As shown in FIG. 10, a conventional lamp such as a clearance lamp or a turn signal lamp has a lamp body 1 having a space for mounting the lamp, restrictions on the shape of the rear side of the lamp body, light distribution, or the like. There is known a lamp having a structure in which the reflector 2 formed on the inner peripheral surface is divided into a plurality of reflecting surfaces 3, 4, and a step 6 is formed between the reflecting surfaces. When such a lamp is attached to a corner of a vehicle, the stepped portion 6 between the reflecting surfaces is seen through the lens 8 from the side of the vehicle, which is unattractive. The side area of the lens 8 emits light mainly by the direct light from the bulb 7. However, the direct light emitted just before the reflection surface emphasizes the step 6 and causes the lens 8 to emit light, so that the lens 8 corresponds to the step 6. There was also the problem that the difference between light and dark was formed, which was very noticeable.

The present invention has been made in view of the above-mentioned problems of the prior art,
The purpose is to provide a lamp that is attached to a vehicle corner, and has a structure in which a stepped portion between a plurality of reflecting surfaces that forms a reflector is provided to the side of the vehicle up to the edge of the reflector in view of light distribution and the like. The purpose is to eliminate the poor appearance due to the stepped portion between the reflecting surfaces.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a vehicular lamp according to the present invention is a lamp that is attached to a vehicle corner part, wherein a lens is attached to a front opening of a lamp body that extends to the side of the vehicle, and a lamp is attached. A reflector that is formed in the body and reflects the light source light to the lens side is divided into a plurality of reflecting surfaces, and a step formed between the reflecting surfaces is provided up to the reflector side edge portion on the side of the vehicle. A shade for hiding the step is formed on the side edge portion.

[Action]

The step portion exposed at the side edge portion on the vehicle side of the reflector is hidden by the shade formed at the reflector side edge portion, so the step portion cannot be seen through the lens. Further, since the bulb direct light emitted along the step portion is blocked by the shade, the difference in brightness between light emission corresponding to the step portion does not appear on the lens.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 9 show a right rear combination lamp in which a turn signal lamp, a backup lamp, a tail & stop lamp and a reflex reflector are integrated, and FIG. 1 is a front view of the rear combination lamp, FIG. 2 is a longitudinal sectional view thereof (the line shown in FIG.
II-II) and FIGS. 3 to 5 are horizontal cross-sectional views of the rear combination lamp, respectively, taken along line III-III, line IV-IV, and line V-V shown in FIG. 1, respectively. Sectional view, FIG. 6 is a perspective view of the lamp body, FIG. 7 is a front view showing a light reflecting surface formed on the inner peripheral surface of the lamp body, and FIG. 8 is a perspective view of a reflector of a tail & stop lamp. FIG. 9 is a front view of the light emitting surface of the front lens of the tail and stop lamp.

In these drawings, reference numeral 10 is a vertically long container-shaped lamp body of a rear combination lamp, and the interior of the lamp body is arranged in order from above by a horizontally extending shade 15 from the top to a turn signal lamp lamp chamber space A, a backup lamp lamp chamber space B, A bulb 16 which is defined in the lamp room space C of the tail and stop lamps, and which is installed in the respective lamp room spaces A to C in the bulb insertion holes 50A to 50C opened at the rear top of the lamp body of each lamp 16 (16a to 16c) are arranged. A continuous seal groove 17 is formed at the peripheral edge of the front opening of the lamp body 10 and at the tip of the shade 15 forming the lamp chamber space, and the seal leg 22 of the front lens 20 is formed by this seal groove.
It is engaged with 17 and integrated as a lamp. Reference numeral 18 is a sealing agent loaded in the seal groove 17.

The front lens 20 is, in order from the top, an amber lens 20A for a turn signal lamp, a white lens 20B for a backup lamp, a red lens 20C for a tail and stop lamp, and a reflex reflector 20D, which are welded at their respective joints. It is an integrated one. Front lens 20
As shown in FIG. 3 to FIG. 5, is curved so as to be convex toward the front, and when the lamp is mounted on the vehicle, the left edge of the lens 20 is the rear surface portion 30 of the vehicle and the right side of the lens 20. The edge portion is in the same state as the vehicle side surface portion 32.

Reflectors 9 (9A to 9C) coated with silver are formed on the inner peripheral surface of the lamp body 10 forming the lamp chamber spaces A to C. The reflectors 9A to 9C correspond to the front areas 20A ₁ , 20B ₁ and 20C ₁ of the front lens 20, and are parabolic main reflection surfaces 11 that reflect the light emitted from the filament of the bulb 16 forward.
And (11 A- 11 C), the oblique front region 20A ₂ of the front lens 20, 20
Corresponding to B ₂ and 20C ₂ , it is composed of a sub-reflecting surface 12 (12A to 12C) that reflects the light emitted from the filament of the bulb forward. Therefore, the front areas 20A ₁ , 20B ₁ , 20C ₁ of the front lens emit light by the light reflected by the main reflection surface 11 (11A to 11C), and the oblique front areas 20A ₂ , 20B ₂ , 20C ₂ of the front lens are the sub-reflection surfaces. 12
Light is emitted by reflected light at (12A to 12C). Therefore, sufficient light emission is obtained not only in the front regions 20A ₁ , 20B ₁ , 20C _{1 of the} front lens 20 but also in the oblique front regions 20A ₂ , 20B ₂ , 20C ₂ close to the side of the vehicle and The visibility from is good. The sub-reflecting surface 12C in the tail & stop lamp has the same focal position as the main reflecting surface 11C,
It is composed of a plurality of reflecting surfaces in the form of multiple reflecting surfaces 12C ₁ , 12C ₂ and 12C ₃ , which have different back-side engraving conditions (focal lengths), and sub-reflecting surfaces 12C ₁ and 12C ₂ The reflected light at illuminates the oblique front area 20C ₂ of the front lens, and the sub-reflecting surface 12C ₃ causes the upper left area 20C ₅ of the front lens to emit light. The symbols 20A ₃ , 20B ₃ and 20C ₃ are reflectors 9A and 9
This is a region in which the reflected light at B and 9C is not guided and is emitted by the direct light from the bulbs 16a, 16b, and 16c.

In addition, between the main reflection surface 11 and the sub-reflection surface 12 and between the sub-reflection surfaces 12C ₁ and 12C.
Steps 14 (14A, 14B, 14C) between C ₂ and 12C ₃ respectively
Is formed, the sub-reflection surface 12 is in a state of being recessed to the back side compared to the main reflection surface 11, and this recessed shape extends to the right edge of the reflection surface. However, a shade 40 (40A, 40B, 40C) having the same height as the maximum height of the sub-reflecting surface is formed along the side edge on the right side edge of the reflecting surface. Is hard to appear on the side edge. In particular, as shown in FIG. 8, although the step portion 14C ₁ which is formed on the reflector 9C of the tail & stop lamp extends from the valve insertion hole 50C located to the side edges,
Since the shade 40C hides the stepped portion 14C _1, step section 14C ₁ through the lens 20 from the vehicle side is made exactly the appearance appearance invisible good. Furthermore, the lens 20 along the step 14C ₁
Since the direct light from the bulb heading to is blocked by the shade 40C,
There is no difference in brightness between the light emitting surface of the lens 20 and the step portion 14C ₁ .

Incidentally located in the stepped portion 14C _2, 14C ₃ are spaced from each lens 20 position, because it is hidden in the step pattern is formed on the functional color and the rear surface of the further lens, the stepped through the lens 20 portion 14C _2, 14C _{The 3} is never visible. The same applies to the stepped portions 14A and 14B formed on the reflectors in the turn signal lamp and the backup lamp.

Further, a rectangular groove 52 surrounding the lamp insertion hole 50C is formed on the inner peripheral surface of the lamp body of the tail & stop lamp, and a cylindrical shade (not shown) is attached to this groove 52 to cover this area. It can be used as a backup lamp or as a rear fog lamp with a metal reflector (not shown) attached to the main reflection surface 11C, and can also be used as a lamp body of a rear combination lamp for Europe. For Europe, the turn signal lamp area will be the tail and stop lamp and the backup lamp area will be the turn signal lamp.

The front lens 20 has a red or amber color that is a functional color for each lamp, and steps are formed on the lens to make it difficult to see the inside of the lamp.
The lateral region of the lamp extends rearward of the lamp body, close to the reflection surface (hereinafter referred to as a dummy reflection surface) 26 (26A, 26B, 26C) inside the lamp body where the light emission of the bulb filament does not reach directly. . This dummy reflecting surface 26 is a lamp body whose inner peripheral surface is coated with silver, and reflects external light that has passed through the front lens 20 when the lamp is not lit during daytime,
The side areas 20A ₄ , 20B ₄ , 20C ₄ of the front lens correspond to the main reflection surface 11 and the front lens areas 20A ₁ , 20B ₁ , 20C ₁ and the sub-reflection surface 12
It has an effect of oblique front lens region 20A _2, 20B _2, 20C ₂ and the same degree of tint corresponding to. That is, it has a function of making the front lens look large and uniform when the lamp is not lit.

And if the shade to the right edge of the reflector 9 (9A~9C) 40 (40A~40C) is not formed, the sub-reflection surface 12C ₁ of the reflector of the tail & stop lamp on the dummy reflecting surface 26, 12C ₂ between The stepped portion 14C _{1 of} is exposed, and the area equivalent to the stepped portion 14C ₁ appears to be dark on the front lens 20, or the curved surface of the sub-reflecting surface 12 (12A, 12B, 12C) can be seen through the lens 20. There is a problem that a difference in brightness and darkness is caused. However, in this embodiment, the dummy reflecting surface 26 corresponding to the side regions 20A ₃ , 20B ₃ and 20C ₃ of the front lens is used.
And the reflecting surface 11 corresponding to the diagonal front areas 20A ₂ , 20B ₂ and 20C _2.
The shades 40 (40A, 40A, 40A, 40A, 40B,
B, 40C) are formed. Therefore, each dummy area 26A, 26
B and 26C are continuous strips with a uniform width in the vertical direction, and the diagonal front regions 20A _{2 to} 20C ₂ and the side regions 20 of the front lens are
No discontinuous difference in brightness between A _{4 and} 20 C ₄ is formed.
Also, the diagonal front area 20A ₂ (20
B ₂ , 20C ₂ ) and the side area 20A ₄ (20
B _4, 20C ₄₎ between, for emitting a small amount of area _{20A 3 (20B 3, 20C 3} ) is formed, the brightness of the lamp in the shade 40 forming position gradually to emitting only by direct light valve There is also a gradation effect that changes to.

Further, since the focal lengths of the main reflecting surface 11 and the sub-reflecting surface 12 are different from each other, the front lens 20 has a main reflecting surface 11 extending radially at the position where the step portion 14 is formed when the lamp is turned on, as shown in FIG. Therefore, a difference occurs in the brightness of the lens with each parting line 14a of the sub-reflection surface 12 as a boundary. A filament 44 supported by the stem 42 is provided in the bulb 16, and when the light emitted from the filament 44 is reflected by the main reflection surface 11 and guided to the front lens 20, the stem 42 and the filament 44 are provided.
Appears as a shadow on the front lens 20. Conventionally, the brightness of the front lens is different with the parting line 14a of the front lens as a boundary, and the shadows of the stem 42 and the filament 44 appear radially on the front lens 20 separately from the parting 14a, and the appearance is very bad. was there. However, in this embodiment, as shown by reference numeral 46 in FIG. 9, the positions of the stem 42 and the filament 44 are set so that the shadow of the stem 42 and the filament 44 coincides with the parting line 14a of the reflector appearing on the front lens 20. There is. That is, the position of the bulb 16 in the circumferential direction is set so that the positions of the stem 42 and the filament 44 coincide with the extending direction of the parting line 14a. Therefore, on the front lens 20 when the lamp is lit, the shadow 46 of the stem 42 and the filament 44 and the parting line 14a appear to overlap each other,
The gradation effect that the parting line 14a is not clear, that is, the difference in brightness between the reflection surface corresponding regions 11 and 12 of the front lens is difficult to see, and the appearance of the lamp is good.

[Effect of device]

As is apparent from the above description, according to the vehicular lamp of the present invention, the stepped portion formed on the side edge portion of the reflector on the vehicle side is hidden by the shade formed on the reflector side edge portion. Therefore, the stepped portion cannot be seen through the lens. Further, since the bulb direct light emitted along the step portion is blocked by the shade, the difference in brightness between light emission corresponding to the step portion does not appear on the lens.
Therefore, it is possible to obtain a vehicular lamp which has a good appearance and does not show a bad appearance due to the stepped portion between the plurality of reflecting surfaces forming the reflector.
