Abstract
An elongated light source (50) comprises a subassembly (51) including a base (54), a light engine (10) positioned in mounting means (56) formed with the base; a light guide (58) positioned in spaced apart supports (57), and a cover (62) fixed to the base (54). The light engine (10) comprises a thermally conductive substrate (12) having a dielectric (14) on one side thereof; upper and lower lens guards, (16, 18), respectively, positioned near one end (20) of the substrate (12); at least one LED (22) mounted on the substrate between the lens guards (16, 18); and electrical conductors (24, 26) mounted upon the substrate at another end (28) thereof for supplying power to the LED (22).
Claims9
A light engine comprising:
- a thermally conductive substrate lying in a first plane and having a dielectric on one side thereof;
- upper and lower lens guards extending in a second plane normal to said first plane positioned near one end of said substrate;
- at least one LED mounted on said dielectric between said lens guards;
- a pair of lateral extensions formed with said substrate and projecting therefrom in said first plane;
- a pair of retention barbs associated with said pair of lateral extensions and extending in said first plane;
- and
- electrical conductors mounted upon said dielectric at another end thereof for supplying power to said at least one LED.
An elongated CHMSL light source for an automotive vehicle comprising:
- a subassembly including a base;
- mounting means in the shape of a slot formed in said base;
- a light engine including at least one LED positioned in said slot, said light engine including retention barbs that engaging sides of said slot;
- a plurality of U-shaped supports positioned on said base;
- and
- an elongated cylindrical light guide positioned in said plurality of U-shaped supports in a manner to receive light emitted from said at least one LED, and a cover fixed to said base.
