Producers of plasma lamp
Companies producing or developing plasma lamps include Ceravision, Luxim and Topanga Technologies.
Luxim’s LIFI, or light fidelity lamp, claims 120 lumens per RF watt (ie before taking into account electrical losses). The lamp has been used in Robe lighting’s ROBIN 300 Plasma Spot moving headlight. It was also used in a line of, now discontinued, Panasonic rear projection TV.
Ceravision has introduced a combined lamp and luminaire under the trade name Alvara for use in high bay and street lighting applications. It uses an optically clear quartz waveguide with an integral burner allowing all the light from the plasma to be collected. The small source also allows the luminaire to utilize more than 90% of the available light compared with 55% for typical high-intensity discharge fittings. Ceravision claims the highest luminaire efficacy rating of any light fitting on the market and to have created the first HEP lamp. Ceravision uses a magnetron to generate the required RF power and claim a life of 20,000 hours.
