ABSTRACT:
An assembly adapted to emit electromagnetic radiation made up of an emitter of electromagnetic radiation; a non-reflective ceramic support for the emitter; a substantially transparent crown mounted on the support to define and enclose a space that houses the emitter; and leads attached to the emitter through the support. The combination of the non-reflective support and the transparent crown, and the location of the emitter in the enclosed space enables the emitter to emit electromagnetic radiation in a conical radiation pattern. The radiation pattern appears to have a centroid. This centroid appears to be in a more constant spatial position regardless of the viewing angle as compared with the apparent position of this centroid with other assemblies.
