Dielectric barrier discharge lamps and methods

摘要

Electric lamps wherein material inside a bulb is excited using capacitive coupling through the bulb wall to external electrodes, forming plasma which emits light. Methods described include use of light-emitting material including sulfur and/or selenium, and a circuit for driving the external electrodes.

主权项

1. An electric lamp comprising: a transparent or translucent bulb; material inside the bulb which emits light when electrically excited and which includes sulfur and/or selenium as a vital component; capacitive couplings between electrodes and said material inside the bulb through the wall of the bulb and/or an insulating barrier other than the wall of the bulb, which are electrically driven to create an electric discharge inside the bulb, and which serve as the primary means of energy transfer to material inside the bulb during normal operation after startup; and a drive circuit used to drive said capacitive couplings.
