Description

Description: TECHNICAL FIELD The present invention relates to a vehicle lighting device that warns a following vehicle when a brake is operated.

[Conventional technology]

In a recent automobile, as shown in FIG. 19, a stop lamp 3 is incorporated in a rear projecting end of a rear spoiler 2 provided on a rear upper surface of a vehicle body 1, and a stop lamp 3 is turned on together with a brake light when a brake is operated, so that a following vehicle Driver's attention to prevent further collision accidents (Actual No. 61-190779 and No. 61-190780).
No.).

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

In order to overcome such monotonousness, for example, a method in which the stop lamp 3 is gradually turned off in response to a brake off operation can be considered (Japanese Patent Application No. Sho 63-63).
-319549).

[Problems 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 a brake off operation, all the lights are turned off from the start of turning off the stop lamp 3. If the electric charge required up to this time is to be ensured by receiving the electric charge supplied from the vehicle-mounted battery, wiring connection between the stop lamp 3 and the vehicle-mounted battery is required.

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, The connection wire 3-2 and the grounding wire 3-3 to the ground side are not led out from the stop lamp 3, the grounding wire 3-3 is grounded, and the connection wire 3-2 is connected to the plus side of the vehicle battery. Must be connected.

However, in a general automobile, the plus side power source from the on-vehicle battery does not come directly to the lower side where the stop lamp 3 is arranged, that is, in the trunk room. For this reason, the connection line 3-2 from the stop lamp 3 has to be routed to the center console in the engine room or the vehicle compartment, which imposes a heavy work load on the user side and increases the sales force for the manufacturing side. It will be inevitable.

[Means for Solving the Problems]

The present invention has been made to solve such a problem, and a plurality of light emitting means are arranged in parallel at a predetermined interval in the vehicle body width direction, and these light emitting means are turned on in response to an ON operation of a brake. In the vehicle lamp that gradually turns off the light in response to an off operation of the light emitting means brake that is turned on, the vehicle light is provided with a backup power supply that secures a necessary electric charge from the start of turning off the light emitting means to the complete extinction. .

[Action]

Therefore, according to the present invention, the electric charge required from the start of extinguishing the light emitting means to the complete extinction can be secured by the backup power supply provided externally or internally.

Four prisms 4 located above and below and to the left and right of the central prism 45E
5B, 45D, 45F, 45H has a step portion 46 by the inner end thereof, that is, the side end in contact with the central prism 45E is slightly projected from the prism 45E, and has a flesh from the inner end side to the outer end. The thickness is thin. Therefore, the left and right two prisms 45B and 45H are substantially triangular in lateral cross-sectional shape as shown in FIG. 10, and the upper and lower two prisms 45D and 45F are the first.
As shown in FIG. 1, the vertical cross-sectional shape is also substantially triangular, and the height of the step portion 46 of the lower prism 45F is set larger than that of the upper prism 45D. Also, two prisms on the left and right

Note that h is the reference thickness of the front lens 16.

Such prisms 45A to 45I (However, the central prism 45
(Except E) is formed by changing the step height, the radius of curvature of the surface, etc. as described above, so that the refraction angle and the refraction direction of the light are different, whereby the light 53 emitted from the light emitting diode 19 is prevented. The light 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 the present embodiment, the surface of each prism 45A to 45I is formed into a concave curved surface with an appropriate curvature, but it is not limited to this and various modifications are possible, for example, FIGS. 12 and 13 All the surfaces of the prisms 45A to 45I may be formed to be flat as shown in FIG.

It is composed of a series circuit with this capacitor C1
And power supply unit 101 via line L2 at one end of the series circuit with C2
The cathode of the diode D1 is connected in the line L3 through a line L3 _-1 is connected to the other end, the line L3 _-1
A grounding line L3 _-2 is derived from the connection point between the line L3 and the line L3.

Next, the operation of the stop lamp 13 thus configured will be described. That is, when you step on the brake pedal,
That is, when the brake is operated to be turned on, the stop switch ST is turned on by the operation to turn on the brake, and the brake light STL is turned on by receiving the supply of the power supply voltage (+ B). At the same time, the power supply voltage (+ B) 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, the power supply unit 101
In, the power supply voltage (+ B) is applied to the constant voltage generation circuit 101-1 via the diode D1, and the constant voltage + V _B is generated by turning on the transistor Q3. At the same time, in the backup unit 200, the capacitors C1 and C2 are charged by the electric charge supplied by the power supply voltage (+ B) via the diode D1. On the other hand, the brake signal via the line L1 is also given to the interface circuit 103 to turn on the transistor Q4 thereof, which brings the output of the inverter INV4 to the “H” level. The output of this "H" level inverter INV4 is
It is given to each reset terminal of the shift registers 104-1 and 104-2 of the shift circuit 104, and the level of its output terminals 104a to 104f is set to "L". Therefore, in the driver circuit 105, the outputs of the inverters INV5 to INV10 are all at "H" level, and the transistors Q5 to Q16 are all turned on.
As a result, in the display circuit 106 to which the power supply voltage (+ B) is supplied through the diode D1, the light emitting diode group 19R
-1 to 19R-6 and light emitting diode groups 19L-1 to 19L-
All 6 will be illuminated, which will alert the driver of the following vehicle.

On the other hand, when the stepped brake pedal is released from the foot, that is, when the brake is turned off, the stop switch ST is turned off by turning off the brake, the brake light STL is turned off, and the brake signal is sent via the line L1. Disappears. That is, the power supply unit 101 and the display circuit 1
The supply of the supply voltage (+ B) to diode 06 via diode D1 is interrupted. However, the constant voltage generation circuit 101-1 and the display circuit 106 in the power supply unit 101 are thereafter supplied with the charged charges stored in the capacitors C1 and C2 in the backup unit 200, and the constant voltage generation circuit 101-1 and The power supply to the display circuit 106 is continued. On the other hand, in the interface circuit 103, the transistor Q4 is turned off due to the disappearance of the brake signal, so that the output of the inverter INV4 becomes "L" level and the reset state of the shift registers 104-1 and 104-2 is released. As a result, the clock signal supplied via the clock circuit 102 effectively acts on the shift registers 104-1 and 104-2, and the level of the output terminal 104a is first set to "H" based on this input clock signal. It will be. As a result, the output of the inverter INV5 becomes "L" level, the transistors Q5 and Q6 are turned off, and the light emitting diode groups 19R-1 and 19L-1 at both ends are turned off. Then, based on the clock signal that is continuously input, the level of the output terminal 104b becomes "H" and the output of the inverter INV6 becomes "L" level after a lapse of a predetermined time. As a result, in addition to the light emitting diode groups 19R-1 and 19L-1, the light emitting diode groups 19R-2 to 19L-2 adjacent to the inside of the light emitting diode groups are turned off.
04d, 104e, 104f sequentially become "H" level at intervals of a predetermined time, so that the inner light emitting diode group adjacent to the light emitting diode group which is turned off is turned off in a time division manner, and finally the light emitting diode group 19R -6 and 19L-6 are turned off. That is, the light emitting diode groups 19R-1 to 19R-6, 19L-1, 19L-6 arranged on the printed circuit boards 18-1 and 18-2.
However, the light is turned off so as to flow from the outside toward the center, and when the brake is changed to the off operation, the visibility of the driver of the following vehicle is greatly improved.

Then, after the light emitting diode groups 19R-6 and 19L-6 are extinguished, the transistor Q3 in the power supply unit 101 is turned off due to the discharge of the charged charge of the capacitors C1 and C2 in the backup unit 200, and the control is performed. Supply of constant voltage + V _B to the section is interrupted. As a result, the amount of charge discharged from the backup unit 200 is reduced, and the backup unit 200 is prepared for the next brake ON operation.

That is, the light emitting diode groups 19R-1 to 19R-6, 19L-1
The charge required from the start of extinguishing all lights up to 19L-6 to the complete extinction is secured by the charge load of the capacitors C1 and C2 in the backup unit 200, and after the stop switch ST is turned off, the charge from the vehicle battery is Supply is unnecessary. This eliminates the need to connect the in-vehicle battery to the positive side, and the line L1 and L3 _-2 can be handled by simply connecting them to the stop switch ST side and the ground side, which puts a heavy burden on the user. In addition to being mitigated, the sales force will be strengthened for the manufacturing side as well. Further, by providing such a backup unit 200, the constant voltage + V _B supply to each circuit in the control unit is always cut off after all the light emitting diode groups are turned off, which may cause noise. A malfunction does not occur in the control unit, the control unit operates reliably by the generation and disappearance of the brake signal via the line L1, and the light emitting diode groups 19R-1 to 19R-6,
The special effect of being able to prevent erroneous lighting of 19L-1 to 19L-6 is achieved.

FIG. 15 shows the lighting / extinguishing patterns of the light emitting diode groups in response to the brake on / off operation when the number of the light emitting diodes 19 arranged on the printed circuit boards 18-1 and 18-2 is 12 each. FIG. FIG. 7A shows a pattern when the brake is off, and includes the light emitting diode groups 19R-1 'to 19R.
-3 'and the light emitting diode groups 19L-1' to 19L-3 'are all off. FIG. 7B shows a pattern when the brake is turned on. When the brake is turned on, the light emitting diode groups 19R-1 'to 19R-3' and the light emitting diode group 19L are displayed.
All of -1'-19L-3 'lights up. If the brake is turned off from this state, first t1 seconds have elapsed (for example, 0.
After 1 second), the light emitting diode groups 19R-1 ', 19L on both ends
-1 'goes out ((c) in the same figure). Then, after t2 seconds have passed from the OFF operation (for example, 0.2 seconds have passed), in addition to the light emitting diode groups 19R-1 ′ and 19L-1 ′, the light emitting diode groups 19R-2 ′ and 19L-2 adjacent to the inside thereof are also added. 'Is turned off ((d) in the same figure), and after t3 seconds (for example, 0.3 seconds) from the OFF operation, the light emitting diode group 19R-2', 1
In addition to 9L-2 ', the last light emitting diode groups 19R-3' and 19L-3 'adjacent to the inside of the 9L-2' are extinguished ((e) in the same figure). As is clear from this lighting / extinguishing pattern, when the brake is turned off, the light emitting diode group 19
The lights of R-1 'to 19R-3' and 19L-1 'to 19L-3' are turned off so that they flow from the outside toward the center, and the visibility of the following vehicle driver is greatly improved.

In the embodiment, the time T from the fully lit state to the completely extinguished state of the light emitting diode groups 19R-1 to 19R-6, 19L-1 to 19L-6, which accompanies the brake off operation, is calculated as follows. It is a fixed value that is determined based on the cycle of the clock signal to be transmitted. That is, the time division time of the light emitting diode group that is sequentially turned off from the outside is set as a certain fixed value. 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 for varying the cycle of the transmitted clock signal,
By adjusting the volume 107, the time division time of the light emitting diode group is set to an arbitrary value according to the user's preference,
It becomes possible to change the required time T from the fully lit state to the fully extinguished state of the light emitting diode group. FIG. 16 shows the mounting state of the volume 107 in the actual configuration. The control board 100 is electrically connected to the control board 100 by the cord 108, and the volume 107 is not provided in the lamp unit 17, and the adjustment knob thereof is not provided. The portion 107a is provided so as to be exposed to the outside from the front lens 16 (see FIGS. 17 and 18). The volume 107 does not necessarily have to be built in the lamp unit 17, and may be arranged, for example, on the driver's seat side.

Further, in the embodiment, the light emitting diode groups 19R-1 to 1
The 9R-6, 19L-1 to 19L-6 are time-divisionally turned off from the outside toward the center, but it may be turned off from the center to the outside, or may be turned off at random. It may be configured such that Furthermore, in the embodiment, although the four light emitting diodes 19 are turned off as one group, it goes without saying that the four light emitting diodes 19 need not necessarily be set as one group.
One of the two may be turned off in a time-sharing manner as a group, and its modification is free.

Further, in the embodiment, the stop lamp 13 is shown as an example incorporated in the rear spoiler 11, but it may be incorporated in a mounting body such as a spoiler arranged on the roof of the vehicle body, or mounted on the rear window inside the rear window. You may do it.

Further, although the backup unit 200 is externally attached in the above-described embodiment, as shown in FIG. 1B, in the power supply unit 101, a large-capacity capacitor is provided between the cathode of the diode D1 and the ground. It is also possible to connect a parallel circuit of C1 ′ and C2 ′ and incorporate this in the stop lamp 13 as the backup power supply unit 101-2.
By doing so, line L3 _-1 rather than line L3
It is no longer necessary to branch and derive L3 _-2 and L3, and it is no longer necessary to derive line L2.
The cost can be further reduced as compared with the method of externally attaching the 200, and the risk of failure due to reverse connection does not occur.

In addition, the light emitting diode groups 19R-1 to 19R-6, 19L-1 to 19L
It is not always necessary that the backup unit 200 or the backup power supply unit 101-2 be used to secure the electric charge required from the start of the extinction of -6 to the complete extinction. For example, a charging pond may be used as a backup power source, and the charging pond may be externally attached to or built in the stop lamp 13.

〔The invention's effect〕

As is clear from the above description, according to the vehicle lighting device of the present invention, the backup power supply provided externally or internally ensures the necessary electric charge from the start of turning off the light emitting means to the complete turning off. , It is not necessary to connect the on-vehicle battery to the plus side, which greatly reduces the work load imposed on the user side and also has an excellent effect that the sales force is strengthened for the manufacturing side.
