Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle lamp that warns a following vehicle when a brake is operated.

[Conventional technology]

In recent automobiles, a stop lamp 3 is built into the rear protruding end of a rear spoiler 2 provided on the rear upper surface of the vehicle body 1, as shown in Fig. 19, and this is turned on together with the brake lamp when the brake is operated, thereby preventing the following vehicles from following the vehicle. This is intended to make car drivers more careful and prevent rear-end collisions and the like (Utility Model Application No. 61-190779, Utility Model Application No. 61-190780, etc.).

In such a vehicle lamp, generally, the stop lamp 3, which is turned on in response to a brake off operation, immediately goes out in response to the brake off operation. Therefore, when the brake is turned off, the visual effect for the driver of the following vehicle becomes monotonous.

In order to overcome such monotony, for example, a method can be considered in which the stop lamp 3 is gradually turned off in response to the brake off operation (see the patent application filed in 1983 by the present applicant).
3-319549).

[Problem to be solved by the invention]

However, when such a method is adopted, in order to gradually turn off the stop lamp 3 in response to the brake off operation, the necessary charge from the start of turning off the stop lamp 3 to the time when the stop lamp 3 is turned off is stored in the vehicle. If the electric charge is to be supplied and secured from the battery, a wiring connection is required between the stop lamp 3 and the vehicle battery.

That is, as shown in Fig. 20, in addition to the connection line 3-1 to the stop switch (not shown) that closes/opens in response to the on/off operation of the brake, there is also a connection line 3-1 to the positive side of the vehicle battery. The connecting wire 3-2 and the grounding wire 3-3 to the ground side shall be derived from the 7-branch 3,
Connect the grounding wire 3-3 to the ground and connect it!!A
3-2 must be connected to the positive side of the vehicle battery.

However, in the car -a, the positive power source from the on-board battery does not directly reach the lower side where the stop lamp 3 is arranged, that is, the inside of the trunk room. For this reason, the contact Vtbx3-2 from the stop lamp 3 must be routed to the engine room or the center console in the vehicle interior, which increases the work burden on the user and reduces the sales power of the manufacturer. A decline is inevitable.

[Means to solve the problem]

The present invention has been made to solve these problems, and includes a plurality of light emitting means arranged in parallel at predetermined intervals in the width direction of the vehicle body, and these light emitting means are turned on in response to a brake ON operation. A vehicle lamp that gradually turns off the illuminated light emitting means in response to a brake off operation, which is equipped with a backup power supply that secures the necessary charge from the time when the light emitting means starts to turn off until it is completely turned off. be.

[Effect]

Therefore, according to the present invention, the necessary charge from the start of turning off the light-emitting means to the time when the light-emitting means is completely turned off can be secured by the backup power supply provided externally or built-in.

To explain the configuration of the rear spoiler and stop lamp in Figures 2 to 8, 10 is the rear upper surface of the vehicle body (Figure 4).
, 11 is a wing-shaped rear spoiler which is long in the left and right direction as a mounting body installed on the rear upper surface 10 of the vehicle body via a gasket 12, and 13 is provided on the lower surface side of the longitudinal center of the rear projecting end of the rear spoiler 11. This is a stop lamp in the form of a band long in the left-right direction and disposed within an elongated notch 14 having a predetermined length. The stop lamp 13 has a plate-shaped lamp body 1.
5, and a front lens 16 having a substantially U-shaped vertical cross-section and opening toward the front of the vehicle body, the open end of which is fixed to the front surface of the lamp body 15 (the rear surface of the vehicle body) by ultrasonic welding or the like. A printed circuit board 18-1 which has a lamp unit 17 and has a large number of light emitting diodes 19 mounted inside the lamp unit 17. 18-2 and a control board 100, which will be explained in more detail later, are provided.

It is fixed to the ceiling surface using double-sided adhesive tape 23 (FIG. 6), adhesive, or the like. A communication hole 24 and a communication pipe 25 (FIG. 3, FIG.
The communicating pipe 25 extends toward the front of the vehicle body, and its tip is bent downward to prevent rainwater from entering. The inside of the lighting unit 17 is a communication pipe 25.
Because it communicates with the outside through a 300-degree tube, air can freely circulate, making the temperature and humidity approximately equal to that of the outside. Therefore, generation of water droplets and fluctuations in temperature and pressure due to blinking of the light emitting diode 19 are reduced and prevented. A filter 26 (see FIGS. 3 and 7) is provided at the inner open end of the communication pipe 25, that is, the communication hole 24.
The filter 26 has high air permeability because it is formed of a porous film of fluorine, polyethylene, ultra-high molecular weight polyethylene, acrylic, or the like.

Therefore, air circulation is free. However, it is waterproof by blocking the passage of water.

A cord lead-out hole 29 (FIGS. 3 and 4) for guiding the cord 28 into the rear spoiler 11 is provided in the longitudinal center of the lamp body 15.
A rubber bushing 30 is fitted and fixed to 9. One end of the cord 28 is connected to the electric circuit of the control board 100,
At the other end, a back amplifier unit 200 is externally connected between the lines L2 and L3-t, and the line L
1 and L3-2 pass through the rear spoiler 11 and are guided into the vehicle body through an insertion hole 32 (FIG. 4) provided in the rear upper surface 10 of the vehicle body. A plurality of board mounting portions 33 (FIGS. 3 and 5) are integrally provided on the front surface of the lamp body 15 and protrude toward the front, and the printed circuit board 18 is mounted on the tip surface of the board mounting portions 33 (FIGS. 3 and 5).
-1. 18-2 is vertically fixed by a set screw 34. The light emitting diode 19 is mounted on a printed circuit board 18-1.
The optical axis 47 (Fig. 4) is approximately perpendicular and approximately parallel to the lateral center axis L (Fig. 3) of the vehicle body. It is. In this embodiment, printed circuit boards 18-1 and 1
8-2, 24 light emitting diodes 19 in total, 48 light emitting diodes 19 in total are arranged. The printed circuit boards 18-1 and 18-2 are electrically connected to each other.
A control board 100 is electrically and mechanically attached to the 8-1 side.

The front lens 16 is made of a translucent resin colored red, yellow, etc., and has a box-like shape that is long in the left-right direction.
As shown in FIG. 8, it is inclined toward the rear of the vehicle body, and its lower end is curved with an appropriate curvature and is continuous with the bottom surface 41. Also,
A light control section 43 is formed at the upper end of the inner surface 40 corresponding to each light emitting diode 19, and a side step 4 is formed at the lower end.
4 (Fig. 9) is formed.

As shown in FIGS. 9 to 11, the light control section 43 improves the visibility of the stop lamp 13 from the rear of the vehicle by guiding the light emitted from the corresponding light emitting diode 19 toward the rear of the vehicle. It is composed of a total of nine prism groups 45A to 45■, which are rectangular in approximately the same size and arranged in three rows of three each in the vertical and horizontal directions. It is abbreviated as the center. The central prism 45E is formed into a concave curved shape with an appropriate curvature (R1) as shown in FIGS. 1O and 11. Four prisms 45B, 45D, 45F located above, below, left and right of the central prism 45E,
45H is the inner end, that is, the central prism 45E.
The side end in contact with the prism 45E is slightly protruded from the prism 45E to form a stepped portion 46, and the wall thickness becomes thinner from the inner end to the outer end. Therefore 1. As shown in FIG. 10, the two left and right prisms 45B and 45H have a substantially triangular cross-sectional shape with left and right symmetry.
5D and 45F have the same substantially triangular longitudinal cross-sectional shape as shown in FIG. Step portion 46 of two prisms 45B and 45H
The height of the upper prism 4 is as appropriately shown in FIG.
It is higher than that of 5D and lower than the step height of the lower prism 45F. And four prisms 45B, 45D
, 45F, and 45H are formed into concave curved surfaces with appropriate curvature (Rg).

Four prisms 45A and 45C located at the four corners.

As shown in FIG. 9, the prisms 45G and 451 have a stepped portion 48 that is formed to protrude one step higher than the four prisms 45B, 45D, 45F, and 45H, and the surface 49 thereof is higher than the central prism 45H. inner corner 5 in contact with
It is formed into a concave curved surface with an appropriate curvature so as to be inclined from 0 toward the corner portion 51 at the diagonal line position. Therefore, the plate thickness of the four prisms 45A, 45C, 45G, and 451 is maximum at the inner corner 50 and minimum at the outer corner 51, and the vertical and cross-sectional shapes are substantially triangular. Note that h is the reference thickness of the front lens 16.

These prisms 45A to 45■ (excluding the central prism 45E) are formed by changing the height of the step, the radius of curvature of the surface, etc., as described above, so that the refraction angle and direction of light can be adjusted. As a result, the light 53 emitted from the light emitting diode 19 is refracted in the direction of the optical axis 47 and emitted from the front lens 16 toward the rear of the vehicle body.

In this case, in this embodiment, the surfaces of each of the prisms 45A to 45I are formed into concave curved surfaces with appropriate curvatures, but this is not in any way specific and various changes are possible.
As shown in Figures 12 and 13! Yoni Prism 45A~
All 451 surfaces may be formed flat.

In FIG. 3, the display circuit 106 includes a group of four light emitting diodes 19R-1 to 19R-6 and a printed circuit board Fi18, each consisting of four light emitting diodes 19 arranged sequentially from the right end side in the figure of the printed circuit board 18-1. A light emitting diode group 19L-1 in which four light emitting diodes 19 are sequentially arranged from the left end side of -2.
~19L-6 and resistors R□~RRbr RLI~RL6 connected to each light emitting diode group. Transistor Q5 in driver circuit 105. Q6-Q15. Light emitting diode groups 19R-1, 19L-1 to 19R-6, 19L- are connected to the collector of Q16.
6 are connected to each other. Further, as described above, the back amplifier unit 200 is constituted by a series circuit of capacitors C1 and 02, and a power supply unit 1 is connected to one end of the series circuit of capacitors C1 and 02 via line L2.
The cathode of the diode DI at 01 is connected to the other end, and the line L3 is connected to the other end via the line L3-1, and a grounding line L3-2 is derived from the connection point between the line L3-1 and the line L3. .

Next, the operation of the stop lamp 13 configured as described above will be explained. That is, when the brake pedal is depressed, that is, when the brake is turned on, the stop switch ST is turned on due to the brake ON operation, and the brake light STL is turned on in response to the supply of power supply voltage (10 B). At the same time, the power supply voltage (10B) to the brake light STL is applied as a brake signal to the power supply unit 101 and the interface circuit 103 via the line L1.

As a result, in the power supply unit 101, the power supply voltage (10B) is applied to the constant voltage generation circuit 101-1 via the diode Di, and by turning on the transistor Q3, the constant voltage +V
8 will be generated. At the same time, in the backup unit 200, the capacitors CI and C2 are charged by the charge supplied by the power supply voltage (+B) via the diode D1. On the other hand, the brake signal via line L1 is transmitted to interface circuit lO.
3, turning on its transistor Q4,
As a result, the output of the inverter INV4 is set to the rHJ level. The output of the inverter INV4 at the rHJ level is the shift register 104-1.
It is given to each reset terminal of 104-2, and the level of its output terminals 104a to 104f is set to rLJ. Therefore, in the driver circuit 105, the inverter INV
The outputs of INVIO 5 to INVIO are all at the rHJ level, and all transistors Q5 to Q16 are turned on. This results in
In the display circuit 106 to which a power supply voltage (10 B) is supplied via the diode D1, the light emitting diode group 19R-1
~19R-6 and light emitting diode groups 19L-1 to 19
All L-6 lights are turned on, thereby alerting the drivers of the following vehicles.

On the other hand, when the brake pedal is released from the foot, that is, when the brake is turned off, the stop switch ST is turned off, the brake light STL is turned off, and the brake signal is sent via the line L1. disappears.

That is, supply of the power supply voltage (+B) to the power supply section 101 and the display circuit 106 via the diode D1 is interrupted. However, the constant voltage generation circuit 10 in the power supply section 101
1-1 and the display circuit 106, the capacitors C1 and C2 in the back amplifier unit 200 are
The stored charge is supplied to the constant voltage generation circuit 10.
1-1 and the display circuit 106 continue to be supplied with power. On the other hand, in the interface circuit 103, the transistor Q4 is turned off due to the disappearance of the brake signal, so the output of the inverter NV4 becomes rLJ level, and the shift register 104-1.
The reset terminal 104-2 is released. This results in
The clock signal applied via the clock signal 102 effectively acts on the shift registers 104-1 and 104-2, and based on this input clock signal,
First, the level of the output terminal 104a becomes rHJ. As a result, the output of inverter INV5 becomes rLJ
level, and transistor Q5. Q6 is turned off, and the light emitting diode groups 19R-1 and 19L-1 at both ends are turned off. Then, based on the continuously inputted clock signal, after a predetermined period of time has passed, the level of the output terminal 104b becomes r.
HJ, and the output of inverter INV6 becomes "L" level. As a result, the light emitting diode groups 19R-1, 1
In addition to 9L-1, the adjacent light emitting diode groups 19R-2 to 19L-2 are turned off, and the output terminals 104c, 104d, 104e, 1 are turned off in the same manner.
04f becomes the rHJ level sequentially at predetermined time intervals, the inner light emitting diode groups adjacent to the light emitting diode group that has been turned off are turned off in a time division manner, and finally the light emitting diode groups 19R-6 and 19L-6 are turned off. will turn off. That is, the light emitting diode groups 19R-1 to 19R-6, 1 arranged on the printed circuit board 18-1, 18-2
9L-1 to 19L-6 turn off in a flowing manner from the outside toward the center, and visibility for drivers of following cars is greatly improved when the brake is turned off.

After the light-emitting diode groups 19R-6 and 19L-6 go out, the transistor Q3 in the power supply unit 101 is turned off as the charges in the capacitors C1 and C2 in the backup unit 200 are discharged, and the control The supply of constant voltage +■ to the unit is interrupted. This not only reduces the amount of discharged charge from the backup unit 200, but also prepares for the next brake-on operation.

That is, the light emitting diode groups 19R-1 to 19R-6,
The electric charge required from the start of turning off the lights of 19L-1 to 19L-6 until the lights are completely turned off is secured by the constant charging of capacitors C1 and C2 in the backup unit 200, and after the stop switch ST is turned off, the charge necessary for turning off the lights from the on-board battery is It becomes unnecessary to supply electric charge. For this reason,
There is no need for a connection line to the positive side of the vehicle battery, and it can be handled by simply connecting lines L1 and L3-t to the stop switch ST side and the ground side, greatly reducing the work burden on the user. Moreover, the sales power of manufacturers will also be strengthened.

In addition, by providing such a backup unit 200, after all the light emitting diodes are turned off, the constant voltage +v to each circuit in the control section is always maintained.
1 is cut off, the control section does not malfunction due to noise etc., the control section operates reliably due to the generation and disappearance of the brake signal via the line L1, and the light emitting diode group 19R-1 -19
R-6.

This provides a special effect in that erroneous lighting of the lights 19L-1 to 19L-6 can be prevented.

FIG. 15 shows the lighting/extinguishing pattern of the light emitting diode group in response to the on/off operation of the brake when the number of light emitting diodes 19 arranged on the printed circuit boards 1B-1, 18-2 is 12 each. FIG. Figure (a)
is a pattern when the brake is off, and the light emitting diode groups 19R-1' to 19R-3' and the light emitting diode groups 19L-1° to 19L-3' are all turned off. Figure (b) shows the pattern when the brake is on, and when the brake is turned on, the light emitting diode groups 19R-1' to 1
9R-3'' and light emitting diode group 19L-1' to 1
9L-3' all light up. If you turn off the brake from this state, first after t1 seconds have elapsed (for example, 0.1
seconds), the light emitting diode group 19R-1'' at both ends,
19L-B goes out ((C) in the same figure). Then, after t2 seconds (for example, 0.2 seconds) have passed since the off operation, in addition to the light emitting diode groups 19R-1' and 19L-1'', the light emitting diode group 19R-2' adjacent to the inside thereof is
19L-2° turns off (FIG. 2(d)), and after t3 seconds (for example, 0.3 seconds) have passed since the off operation, the light emitting diode groups 19R-2' and 19L-2'
In addition to the last light emitting diode group 1 adjacent to the inside thereof
9R-3" and 19L-3' are turned off (tel in the figure). As is clear from this lighting/extinguishing pattern, when the brake is turned off, the light emitting diode group 1
9R-1' to 19R-3'', 19L-1' to 19L-3
The lights turn off so that the angle flows from the outside toward the center, greatly improving visibility for drivers of following vehicles.

In addition, in the embodiment, the light emitting diode groups 19R-1 to 19R-6, 19L-1 to
The required time T from the fully lit state to the fully unlit state of 19L-6 is set to a constant fixed value determined based on the period of the clock signal sent from the clock circuit 102. That is, a constant fixed value is defined as the time division time of the light emitting diode group, which is turned off sequentially from the outside. On the other hand, as shown by the broken line in FIG. 14, if the clock circuit 102 is provided with an external volume 107 that changes the period of the output clock signal, the volume 107 can be adjusted to suit the user's preference. By setting the time division time of the light emitting diode group to an arbitrary value, it becomes possible to vary the time T required for the light emitting diode group to go from an all-on state to an all-off state.

FIG. 16 shows how the volume 107 is installed in the actual configuration, and the volume 107 is electrically connected to the control board 100 by the cord 108, and the volume 107 is connected to the lamp unit 17.
07 is installed internally, and its adjustment knob 107a
is provided so as to be exposed to the outside from the front lens 16 (see FIGS. 17 and 18). Note that the volume 107 does not necessarily have to be installed inside the lamp unit 17, and may be arranged, for example, on the driver's seat side.

In addition, in the embodiment, the light emitting diode group 19R-1
~19R-6, 19L-1 to 19L-6 are turned off in a time-sharing manner from the outside toward the center, but the lights may be turned off from the center toward the outside, or they may be turned off randomly. It is also possible to have a configuration such as Furthermore, in the embodiment, the light emitting diode 1
Although the light-emitting diodes 19 are turned off as one group, it goes without saying that the four light-emitting diodes 19 do not necessarily have to be put into one group, and one light-emitting diode 19 may be turned off in a time-sharing manner as one group. , its transformation is free.

In addition, in the embodiment, the stop lamp 13 is shown as being incorporated into the rear spoiler ll, but it may also be incorporated into a mounting body such as a spoiler placed on the roof of the vehicle body, or it may be installed on the rear indoor side of the rear window. You can do it like this.

Furthermore, in the above-described embodiment, the back amplifier unit 200 is attached externally, but as shown in FIG.
Large capacity capacitors CI' and C between O cathode and ground
2' may be connected in parallel, and this may be built into the stop lamp 13 as the backup power supply section 101-2.

By doing this, line L is lower than line L3.
