Abstract

(57) [Abstract] [Purpose] To provide a vehicular lamp that does not require a new vehicle harness to be passed through the vehicle body even when a lamp is retrofitted and can reduce the number of vehicle harnesses passed through the vehicle body. . A control device 30 for controlling lighting of the cornering lamp 10 is integrally provided in a housing 21 of the lamp 10.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp including a control device for controlling lighting of a lamp.

[0002]

[Prior art]

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

[0003]

[Problems to be solved by the device]

 However, in such a vehicular lamp, for example, when the cornering lamp 1 is retrofitted, 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, and the work thereof is required. There were problems such as being troublesome.

Further, since the respective 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, ... Are required.

The present invention has been made in view of the above problems, and an object thereof is to provide a vehicle in which a new vehicle harness does not need to be passed through the vehicle body even when a lamp is retrofitted, and moreover, the vehicle harness is passed through the vehicle body. An object is to provide a vehicular lamp that can reduce the number of harnesses.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that a control device for controlling lighting of a lamp is integrally provided in a lamp body.

[0007]

[Action]

 According to this invention, the control device for controlling the lighting of the lamp is integrally provided in the lamp body. Therefore, even when the lamp is retrofitted, the signal of the adjacent lamp is used to control the retrofitted lamp. By doing so, it is not necessary to pass a new vehicle harness through the vehicle body.

[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 (lamp body) 21 having a bulb 20 and a lens 22 (see FIG. 1) attached to a front opening of the housing. There is. A case 31 of a control device 30 that controls the lighting of the bulb 20 is integrally attached to the housing 21. 23 is a socket in which the bulb 20 is mounted, 24 is a power supply line that supplies power to the bulb 20, 25 is a signal input line connected to the signal line of the turn signal lamp 12, 26 is a power supply line, and 27 is a ground line. Is.

A circuit board (not shown) is provided in the case 31 of the control device 30, and the circuit board includes a power transistor 32 connected in series with the valve 20, as shown in FIG. The smoothing circuit 33 smoothes the blinking signal S1 input to the signal input line 25 and inputs it to the base 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 base of the power transistor, 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 of the turn signal lamp 12 and the control device 30 are connected by a signal input line 25 which is a sub-harness, and the small lamp 13 is connected. Since it is only necessary to connect the power source terminal of the above and the valve 20 with the power supply line 24 which is a sub-harness, and it is not necessary to pass a new vehicle harness through the vehicle body, the installation work thereof is simple.

Further, if the control devices are integrally attached to the respective lamps 12 and 13 in the same manner as described above and the signals of the adjacent lamps are used to control the lighting of the respective lamps, the vehicle body can be controlled. The number of vehicle harnesses to pass through can be reduced.

Although the cornering lamp 10 and the like have been described in the above-described embodiments, the present invention is not limited to this, and it goes without saying that the present invention can be applied to, for example, a turn signal, a hazard, an auto light and the like.

[0016]

[Effect of device]

 According to this invention, since the control device for controlling the lighting of the lamp is integrally provided in the lamp body, when the lamp is retrofitted, the signal of the adjacent lamp is used to control the retrofitted lamp. By doing so, it is not necessary to pass a new vehicle harness through the vehicle body. Further, if a control device is integrally attached to each lamp body and the signal of the adjacent lamp is used to control the lighting of that lamp, the number of vehicle harnesses to be passed through the vehicle body can be reduced.
