Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cornering lamp lighting circuit for lighting a cornering lamp.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 4, a cornering lamp 1, a turn signal lamp 2, a small lamp 3, etc. are electrically connected to a control circuit 4 provided on an instrument panel by a vehicle harness 5, and the control circuit 4 The lamps 1 to 3 are turned on, blinked, and turned off according to the signal.

[0003]

[Problems to be solved by the device]

 By the way, there is a case where the cornering lamp 1 is retrofitted, and in such a case, a new vehicle harness has to be passed through the vehicle body in order to connect the cornering lamp 1 and the control circuit 4, which is a troublesome work. there were.

Further, since each of the lamps 1 to 3 and the control circuit 4 are connected by the vehicle harnesses 5, 5, ..., There is a problem that many vehicle harnesses 5, 5 ,.

The present invention has been made in view of the above problems, and an object thereof is to provide a vehicle harness which does not require a new vehicle harness to be passed through the vehicle body even when a cornering lamp is retrofitted, and which is passed through the vehicle body. It is to provide a cornering lamp lighting circuit that can reduce the number of lamps.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a cornering circuit that converts a blinking signal that blinks a turn signal lamp into a lighting signal and a lighting means that lights a cornering lamp by the lighting signal converted by this conversion circuit. It is characterized by being installed near the lamp.

[0007]

[Action]

 In this invention, since the conversion circuit and the lighting circuit are provided in the vicinity of the cornering lamp, the blinking signal of the turn signal lamp adjacent to the cornering lamp is lit by the conversion circuit even when the cornering lamp is retrofitted. By converting it into a signal, the cornering lamp that is installed later can be turned on by the lighting circuit.

[0008]

【Example】

 An embodiment of a vehicular lamp according to the present invention will be described below with reference to the drawings.

In FIG. 1, 10 is a cornering lamp, 12 is a turn signal lamp, 13 is a small lamp, and 14 is a headlight.

As shown in FIG. 2, the cornering lamp 10 includes a housing 21 having a bulb 20 and a lens 22 (see FIG. 1) attached to a front opening of the housing. A circuit case 30 is integrally attached to the housing 21. 23 is a socket in which the bulb 20 is mounted, 24 is a power supply line for supplying power to the bulb 20, 25 is a signal input line connected to the signal line (not shown) of the turn signal lamp 12, 26 is a power supply line, 27 Is the ground wire.

A circuit board (not shown) is provided in the case 30, and as shown in FIG. 3, a power transistor (lighting means) 32 connected in series to the bulb 20 and a signal are provided on the circuit board. And a smoothing circuit 33 for smoothing the blinking signal S1 input to the input line 25 to convert it into a lighting signal S2 and inputting it to the gate of the power transistor 32. The smoothing circuit 33 is composed of a diode 34, a capacitor 35, resistors R1 to R4 and the like.

When the smoothed signal S2 smoothed by the smoothing circuit 33 is input to the gate of the power transistor 32, the power transistor 32 becomes conductive and the bulb 20 is turned on. That is, the cornering lamp 10 is lit while the turn signal lamp 12 is blinking.

When the cornering lamp 10 is retrofitted, as shown in FIG. 1, the signal line (not shown) of the turn signal lamp 12 and the smoothing circuit 33 are connected by the signal input line 25 which is a sub-harness. It is only necessary to connect and connect the power supply terminal (not shown) of the small lamp 13 and the bulb 20 with the power supply line 24 that is a sub-harness, and it is not necessary to pass a new vehicle harness through the vehicle body. Will be simple. In addition, it is possible to reduce the number of vehicle harnesses because there is no need to pass through the vehicle harness.

[0014]

[Effect of device]

 According to this invention, a conversion circuit for converting a blinking signal for blinking the turn signal lamp into a lighting signal and a lighting means for lighting the cornering lamp by the lighting signal converted by the conversion circuit are provided in the vicinity of the cornering lamp. Therefore, if a cornering lamp is retrofitted, it is not necessary to pass a new vehicle harness through the vehicle body by using the blinking signal of the adjacent turn signal lamp to turn on the retrofitted cornering lamp. The number of vehicle harnesses that can be passed through can be reduced.

[Correction content]

When the smoothed signal S2 smoothed by the smoothing circuit 33 is input to the gate of the power transistor 32 (see A in FIG. 3) , the power transistor 32 becomes conductive and the bulb 20 is turned on. That is, the cornering lamp 10 is continuously lit while the turn signal lamp 12 is blinking. For example, as shown in (B) of FIG. 3, the gate voltage power transistor 32 becomes conductive if the V1, continues to conduction between power over the transistor 32 of the period T1 valve 20 is continuously turned. Then, the signal 0 valve 2 to the input has elapsed time T2 from the stop of flashing signal S1 to the input line 25 so that the lights. That is, the cornering lamp 10 is turned off after a delay of time T2 from the stop of the input of the blinking signal S1 . The delay time T2 is can be arbitrarily set by the time constant due to the capacitor 35 and the resistor R3.
