Patent ID: 7129638

Claim:
A light emitting device, comprising: a base substrate with a cavity and a trough to form a reflective cup; a projecting platform at the base of the cavity, the projecting platform having vertical walls; a light emitter mounted on the projecting platform, the light emitter being smaller in outline than the projecting platform; and a coating having an adhesive material and particles of another substance, wherein the coating is a viscous slurry when applied over and in direct contact with the light emitter in the cavity, and hardens when cured after being applied over the light emitter in the cavity, wherein when the coating, when being a viscous slurry, is applied over the light emitter, the platform, the cavity, and the trough allow the particles in the coating to be evenly settled on and around the light emitter within the cavity before the coating is cured, resulting in an evenly dispersed, uniform thickness particle coating over the light emitter, the thickness of the particle coating being constant with respect to the light emitter.
