ABSTRACT:
An electroluminescent device having a light emitting layer (25) containing phosphor particles (31, 32), wherein the phosphor particles protrude from the light emitting layer to cause the surrounding layers to conform to the protrusions, thus increasing the performance of the lamp. Methods of constructing a lamp using a temperature above the softening temperature of the insulating layer of the device are also disclosed.
