Abstract:
A light emitting device has a cathode-ray tube and power supply. The cathode-ray tube in an embodiment is optimized for emitting a broad electron beam, in one variation a dome-shaped diffusing grid is used to spread the beam. In another embodiment, the device has a base adapted for attachment to a standard lighting fixture.
