Abstract
Automotive emblem lighting assemblies, and methods of making. One embodiment comprises a bezel mounted to a transparent/translucent lens, with junction therebetween which can be sealed. Viscous curable material is dispensed upon the lens rear and bezel. Bubbles within the viscous material are removed. A housing is bonded with the viscous material and bezel/lens. The curable material is cured and seals the assembly. A light source shines through the lens. The lens can have an emblem shaped recess or recesses. Part of the lens rear can be coated with substantially opaque material. A reflective-transmissive material coats at least part of the lens rear for light transmission/reflection. Diffusion can be by a diffusing agent in the viscous material, reflective surface on the light source, or diffusing material on the lens. Modifications: lens with no substantially opaque coating, an emblem shaped lens, reflective-transmissive material on the lens rear, and no bezel. The lens and housing can interfit, with the cured material sealing their junction. The lens rear can be curved or even. Another modification: lens and housing do not interfit. Sealer dispensed over the lens perimeter, housi…
