Cathodoluminescent garnet lamp










Image Number 4 for United States Patent #4792728.

A cathodoluminescent lamp in the form of a vacuum diode or triode uses a self-supporting YAG crystal as the light emitter. The crystal shape can be selected (spherical, slab, bar) for desired effect and light trapping is turned to advantage by selectively coating the crystal surface to provide for preferential light emission.
