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:
- a first plate comprising a heat-conducting material;
- a second plate opposite the first plate and comprising a light-transmitting material;
- an emitter comprising a source of ultraviolet (UV) light, between the first plate and the second plate;
- a light-reflective material between the emitter and the first plate;
- and
- a cathode between the emitter and the second plate, wherein the cathode has an opening formed therein, and wherein, in operation, the UV light from the emitter passes through the opening and through the second plate.
3 more elements
An apparatus, comprising:
- a container;
- and
- a plurality of ultra-violet (UV) field-emission lamps (FELs) disposed on at least one surface of the interior of the container, wherein each UV-FEL in the plurality comprises:
- a first plate comprising a heat-conducting material;
- a second plate opposite the first plate and comprising a light-transmitting material;
- an emitter comprising a source of UV light, between the first plate and the second plate;
- a light-reflective material between the emitter and the first plate;
- and
- a cathode between the emitter and the second plate, wherein the cathode has openings formed therein, and wherein, in operation, the UV light from the emitter passes through the openings and through the second plate.
6 more elements
An apparatus, comprising:
- a handle;
- and
- at least one ultra-violet (UV) field-emission lamp (FEL) coupled to the handle, wherein the UV-FEL comprises:
- a first plate comprising a heat-conducting material;
- a second plate opposite the first plate and comprising a light-transmitting material;
- an emitter comprising a source of UV light, between the first plate and the second plate;
- a light-reflective material between the emitter and the first plate;
- and
- a cathode between the emitter and the second plate, wherein the cathode has openings formed therein, and wherein, in operation, the UV light from the emitter passes through the openings and through the second plate.
