Abstract
Improved ultraviolet field-emission lamps can be safely deployed close to people because they eliminate the use of toxic materials, mitigate heating issues, and emit light in a wavelength range that is safe for human exposure.
Claims30
A device, comprising:
- an emitter of light;
- a first element coupled to the emitter, the first element comprising a heat-conducting material and operable for extracting heat from around the emitter;
- a second element comprising a light-transmissive material;
- a light-reflective material coupled to and between the emitter and the first element;
- and
- an electrode coupled to the second element and disposed between the emitter and the second element, wherein the electrode is configured to allow light produced by the emitter to pass through the light-transmissive material of the second element.

A device, comprising:
- a first plate comprising a heat-conducting material;
- a second plate comprising a light-transmissive material;
- an emitter of light, between the first plate and the second plate;
- a light-reflective material between the emitter and the first plate;
- and
- an electrode between the emitter and the second plate, wherein the electrode is configured to allow light produced by the emitter to pass through the light-transmissive material of the second plate.
