Vehicle lamp
First Claim
1. A vehicle lamp assembly comprising a housing and a lens, said housing and said lens cooperating to define a hollow lamp chamber, a light source fixing face arranged in the lamp chamber, a plurality of lamps arranged on the light source fixing face, and a power source connecting portion formed on a part of said lamp chamber, characterized in that said housing is made of resin having a thermal conductivity improved by adding a filler thereto, said housing has an inner face on which face circuit patterns for electrical contact with each lamp are integrally formed and curved guide portions for positioning the lamp, said guide portions being used as the light source fixing face, the housing also having terminals protruding from the fixing face to the outside of the housing, which terminals serve as the power source connecting housing and said assembly have a large clearance gap, formed between the housing and lens, along a long-axis direction of the vehicle lamp and said housing and said lens being joined through a flexible seal member arranged in said gap to seal said lamp chamber.

Abstract
A vehicle lamp is mounted on vehicles such as automobiles. The lamp has an inner chamber constructed by a lamp housing and a lens, respectively having long shapes. In the chamber, there is a long light source fixing face member on which plural light sources are fixed. All light sources or electric bulbs are neatly fitted to convex or concave guide portions. Circuit patterns are printed on an inner face of the housing. Terminals of the light sources come into contact with the circuit patterns. The housing is made of particular synthetic resin having a good heat conductivity, so that no heat is accumulated in the chamber.
