Abstract:
An LED includes a chip having a light emitting surface, and a coating of phosphor-containing material on the light emitting surface. Phosphor particles are arranged in a densely packed layer within the coating at the light emitting surface, and such that the light emitting surface is in contacting relationship with the phosphor particles.
