Problems solved by technology

[0006] In the proposed heat dissipation structure, in addition to the FPC and heat sink, a sub-board needs to be provided separately for heat dissipation, and the number of parts constituting the lamp increases, which is the main cause of lamp size and high cost.
In addition, when assembling the lamp, it is necessary to connect the sub-board to the heat sink, and then assemble the heat sink into the lamp housing, resulting in troublesome work.

Abstract

A vehicular lamp including a light source unit including a light-emitting element (14) inside a lamp housing (1); a planar wiring member (13) on which the light-emitting element (14) is mounted; and a support substrate (11) having a flat portion that supports the planar wiring member (13). The support substrate (11) is formed from a plate having high thermal conductivity, the planar wiring member (13) is fixed to the flat portion of the support substrate (11), and a portion of the support substrate (11) is fixedly supported inside the lamp housing (1).

Description

technical field [0001] The present invention relates to a vehicular lamp using a light emitting element as a light source, and more particularly to a vehicular lamp having a light emitting element mounted on a flexible circuit board and housed in a lamp housing. Background technique [0002] Lamps using light-emitting elements such as LEDs (light-emitting diodes) as light sources have been proposed as recent vehicle lamps. In such a lamp, when a plurality of LEDs are provided in order to obtain the amount of light required by the lamp, as described in Patent Document 1, it is configured that a plurality of LEDs are mounted on a flexible printed circuit board (FPC), and the FPC is built in structure inside the lamp housing. On the other hand, in order to improve the light-emitting characteristics of LEDs, a heat dissipation structure for dissipating the heat generated by the LEDs is required. As this heat dissipation structure, for example, it is described in Patent Document...
