保護することは難しい。[Problems to be Solved by the Invention] In a lamp provided with a heat shield, the heat generated by the bulb is reflected by the heat shield, so that a certain heat shielding effect can be obtained. When heat is generated, heat is released (radiated) to the housing side, and thus it is difficult to reliably protect the housing from heat generated by the valve.

面を熱吸収面に形成したことを要旨としている。According to the present invention, a heat shield for protecting the housing from the heat generated by the light source bulb is provided at a predetermined distance from the housing, and the surface of the housing facing the heat shield is heated. The gist is that it is formed on the reflection surface, and the housing-facing surface of the heat shield is formed on the heat absorption surface.

Further, even if heat is released from the heat shield, the heat is reflected by the heat reflecting surface of the housing and absorbed by the heat absorbing surface of the heat shield, so that the heat shielding effect of the housing is further enhanced. .

In FIG. 1, reference numeral 1 denotes a synthetic resin housing forming a lamp, 2 denotes a front lens, and 3 denotes a light source bulb. Reference numeral 4 denotes a metal heat shield for protecting the housing. In the illustrated example, the heat shield 4 is formed in a box shape so as to face the upper part, the bottom part, and the rear part of the housing 1. 5a, 5b
Is a pair of grooves having an L-shaped cross section provided integrally with the housing, and the box-shaped heat shield 4 is inserted into the grooves 5a and 5b by inserting protruding claws 4a formed on the edges thereof into the grooves. Is to be retained.
