Abstract
Lamp materials, e.g. a phosphor layer and a dielectric layer, are roll coated onto a release layer. A photodetector is coated with a translucent conductive layer and the lamp materials are laminated to the transparent conductive layer. The release layer is removed and a protective coating is applied to the dielectric layer. A resin coating is optionally applied to the transparent conductive layer prior to lamination to improve adhesion. The protective coating can be incorporated into the lamp materials prior to lamination. The release layer can be coated by screen printing or other deposition technique rather than by roll coating.
