The

  According to the above configuration, the LED 4 is integrally attached to the step portion 21 of the base portion 2 in advance, and the base portion 2 is assembled in the lamp housing 1 together with the reflector 3A (3). In addition, the light emitting circuit board 6 is attached to the board connector 9 of the base part 2, and the socket 7 with a connector that supports the incandescent bulb is attached to the bayonet mounting hole 22 a of the overhang part 22 of the base part 2. Further, the power supply side connector 8 is fitted into the connector portion 72 of the socket with connector 7 to constitute a rear lamp.

FIG. 7 is a block wiring diagram for explaining an electrical connection circuit between the socket with connector 7 and the light emitting circuit board 6 with respect to the base portion 2. The power supply side connector 8 fitted to the connector portion 72 of the socket with connector 7 is connected to a lighting cord 81 connected to a lighting control device on the vehicle body side, and here supplies power for controlling lighting of the incandescent bulb 5. One incandescent line L1, two LED lines L2 and L3 that supply power for controlling the lighting of the plurality of LEDs 4 as tail lamps or stop lamps, and a single ground line L4 that is common to the incandescent bulb 5 and the LED 4 It consists of a total of four lines. And the incandescent line L1 is connected to the contact electrode 71a provided in the socket part 71 of the socket 7 with a connector, and is electrically connected to the incandescent lamp 5 supported by the socket part 71. Further, a total of three lines of the two LED lines L2, L3 and the ground line L4 are respectively connected to the three contact electrodes 71d provided on the flange 71b of the socket 7 with connector, and the socket 7 with connector is connected to the bayonet. When mounted in the mounting hole 22a, these three contact electrodes 71d are in electrical contact with a contact pad 23b disposed facing the bayonet mounting hole 22a, and are further electrically connected to the energizing path 23 of the base portion 2.

Since a part of the contact piece 91 of the board connector 9 is connected to the energizing path 23 connected to the LED lines L2 and L3 and the ground line L4, the connector piece 61 of the light emitting circuit board 6 is connected to the board connector 9. When inserted, the light emitting circuit of the light emitting circuit board 6 is electrically connected to these lines L2, L3, and L4 via the connector piece 61. Further, the other part of the contact piece 91 of the board connector 9 is connected to the plurality of LEDs 4 via the energization path 23.

For example, when the lighting power of the tail lamp is input from the lighting control device on the vehicle body side through the LED line L2, the lighting power is input to the light emitting circuit board 6, and the light emitting circuit board 6 supplies a predetermined level of power to the LED 4. The tail lamp is turned on. When the stop lamp lighting power is input through the line L3, the light emitting circuit board 6 supplies a predetermined level of power to the LED 4 to emit light, and the stop lamp is turned on.

  Further, in the socket 7 with connector, since the contact electrode 71a of the socket portion 71 is electrically connected to a part of the connector terminal 72a of the connector portion 72, it is inputted from the lighting control device on the vehicle body side through the power supply side connector 8. The lighting power of the backup lamp is directly supplied from the connector terminal 72a to the contact electrode 71a, and further supplied to the incandescent lamp 5, so that the incandescent lamp 5 is turned on, and the backup lamp is turned on.

  Therefore, in this rear lamp, except for the electric cord 81 connected to the power supply side connector 8, an electric cord for controlling lighting of a plurality of LEDs and one incandescent bulb is completely unnecessary. That is, the electric power supplied through the power supply side connector 8 fitted to the connector part 72 of the connector-attached socket 7 is directly supplied to the incandescent lamp 5 in the socket part 71 of the connector-attached socket 7. Further, the same electric power is directly supplied from the three contact electrodes 71d of the socket 7 with connector to the energizing path 23 of the base portion 2 that is in electrical contact therewith. Then, power is supplied to the light emitting circuit board 6 from the energizing path 23 by electrical contact between the contact piece 91 and the connector piece 6 in the board connector 9. The light emitting circuit board 6 supplies necessary power to the current path 23 via the board connector 9 to control light emission of the LED 4 based on the power input through the current path 23, and the controlled power is supplied to the current path 23. To the plurality of step portions 21, and the LEDs 4 mounted on each step portion 21 emit light.

  In this way, the base portion 2 is configured as a printed circuit board, and an electric cord for controlling lighting is not required at all. Therefore, the configuration of the base portion 2 is simplified and manufacturing becomes extremely easy. The number of components of the electrical system can be reduced, and the structure can be simplified and the lamp can be made smaller and lighter. In addition, a highly reliable lamp can be configured without causing deterioration or damage of the electric cord. Furthermore, the assembling work when assembling the rear lamp to the car body is simplified. That is, the lid 14 of the lamp body 11 of the rear lamp attached to the vehicle body is opened, and the light emitting circuit board 6 is attached to the board connector 9 through the opening 13. Further, the socket 7 with connector is fitted into the bayonet mounting hole 22a of the overhanging portion 22 through the opening 13, and then the power supply side connector 8 is fitted into the connector portion 72 of the socket 7 with connector. can do.

  In the first embodiment, the board connector 9 is composed of a resin base material that constitutes the base portion 2 including the contact piece 91 and a conductive material that constitutes the current-carrying path 23. The metal member for forming is unnecessary, and the number of parts can be reduced also in this aspect. Furthermore, since the socket with connector 7 of Embodiment 1 can be obtained as it is or with only a part of the configuration of the socket with connector provided in the conventional vehicle lamp, it is inexpensive using existing parts. It is possible to construct a lamp.

  In the first embodiment, since the light emitting circuit board 6 can be attached to and detached from the base portion 2 from the outside of the lamp housing 1, the light emitting circuit board 6 can be easily replaced, which is advantageous in terms of maintenance. It is possible to replace the light-emitting circuit board with a different electrical standard, and it is also possible to configure a lamp with a different light-emission standard.

(Embodiment 2)
In the first embodiment, the LEDs 4 are mounted on the stepped portions 21 of the base portion 2 by soldering or the like. However, if it is difficult to apply a so-called reflow method at the time of soldering, the LEDs may be unitized. FIGS. 8A and 8B are an external perspective view and a cross-sectional view of the second embodiment, and only a part of the stepped portion 21 is shown here. In each step portion 21 of the base portion 2, a light source connector 9 </ b> A is formed on a part of a wall that becomes a boundary between adjacent step portions. Further, the LEDs 4 mounted on each step portion 21 are mounted on a small light source substrate 4A independent of the base portion 2, and a connector piece 41 provided on one side of the light source substrate 4A can be attached to and detached from the light source connector 9A. In addition, the light source substrate 4A is configured to be electrically connected to the energization path 23 on the back surface of the base portion 2 when mounted.

The light source substrate 4A has a conductive circuit 42 formed of a conductive film having a required pattern on the back surface, and is electrically connected to a mounting electrode 43 provided on the front surface through a through hole 44. A part of the conductive circuit 42 is extended to the back surface of the contact piece 41. In the LED 4, the electrode 4a is mounted on the mounting electrode 43 on the surface of the light source substrate 4A by soldering or the like, and is unitized by these.

No attachment is necessary. Since the reflow method can be applied when the LED 4 is mounted on the light source substrate 4A, it is effective when it is difficult to mount the LED 4 on the base portion 2 as in the first embodiment by the reflow method, and the lamp assembly operation is simplified. Can be realized. In the second embodiment, since the light source substrate 4A can be replaced, maintenance such as replacement of the LEDs 4 mounted on the light source substrate 4A is easy, and replacement with different types of LEDs is also possible. Furthermore, since the heat generated in the LED 4 is prevented from being directly transferred to the base portion 2 by providing the light source substrate 4A, the heat resistance required for the base portion 2 can be reduced, and an inexpensive resin material can be used. It can also be adopted. Although the incandescent lamp is not provided in the lamp of the second embodiment, if the incandescent lamp is not supported in the socket with connector 7, the socket with connector 7 for lighting the incandescent bulb of the first embodiment is used as it is. Therefore, even when a lamp other than the backup lamp is combined with the rear lamp, the same connector with a socket can be adopted, and the number of parts can be further reduced.

  The present invention is preferably applied at least in part to a lamp that uses LEDs or a plurality of semiconductor light emitting elements other than LEDs as a light source. Moreover, although the structure which fixed the reflector to the base part was demonstrated in embodiment, it comprised so that optical members other than a reflector, for example, optical members, such as an inner lens and a pseudo reflector, can be fixed with respect to a base part.
