HYBRID METALLIZATION ON PLASTIC FOR A LIGHT EMITTING DIODE (LED) LIGHTING SYSTEM

摘要

Provided is a multi-layer reflective coating for application to a lighting housing assembly, including a polymer substrate adjacent a polymer base coat layer applied to the lighting housing. Atop the polymer base coat layer is an aluminum adhesion layer, followed by a diffusive barrier layer, and a silver reflective layer. The aluminum adhesion layer promotes adhesion between the polymer base coat layer and the silver reflective layer. The diffusive barrier layer prevents aluminum and silver interaction, which could form a silver and aluminum alloy. A spectrum tunable layer is applied atop the silver reflective layer for spectrum tuning the silver reflective layer for maximum compatibility with a light emitting diode (LED) lighting source.
