Claim Text:
1. A multi-layer reflective coating for application to a lighting housing assembly, comprising: an aluminum adhesion promotion layer applied atop a polymer base coat layer, wherein the aluminum adhesion promotion layer comprises a 1-10 nanometer (nm) thick Aluminum (Al) film; a diffusive barrier layer applied atop the aluminum adhesion promotion layer, wherein the diffusive barrier layer comprises a 50-100 nm thick film of NiCr or Ni and Cr; a reflective layer applied atop the diffusive barrier layer, wherein the reflective layer comprises 100-400 nm thick silver (Ag) film; wherein the aluminum adhesion promotion layer promotes adhesion between the polymer base coat layer and the reflective layer; and a spectrum tunable layer applied atop the reflective layer for spectrum tuning the reflective layer to be used with a light emitting diode lighting source.
