Description

  The present invention relates to a vehicular lamp.

  DESCRIPTION OF RELATED ART Conventionally, what mounted the light emitting element of the light source on the flexible board | substrate which can be bent is known as vehicle lamps, such as a headlight for motor vehicles (for example, refer patent documents 1-3). This flexible substrate is suitably used, for example, when the support surface is not flat or when a plurality of light emitting elements are three-dimensionally arranged.

FIG. 5 is an exploded perspective view showing a schematic configuration of a conventional vehicular lamp.
As shown in this figure, the conventional vehicular lamp 100 includes a flexible substrate 140 mounted on a bracket 130 in a lamp chamber formed by a lens member 110 and a housing 120. On the surface (upper surface) of the flexible substrate 140, in addition to the light emitting elements 141,...
