Abstract

The present invention discloses a compact electrode less lamp, and it includes: lamp burner (1); the control circuit (3) fixed inside the shell of control circuit; the electrode less discharge cavity which consists of bubbly glass shell (4) and tubular glass bulb (5) with a groove (6). This electrode less discharge cavity contains some filling materials that could not be ionized and its inner wall is coated with phosphor layer; at least part of coil windings (8)are wound around the transformer core (7) which is installed in the in the described tubular glass bulb. This invented device has great advantages in compact structure, easy start, and aesthetic shape similar to incandescent lamp.

Description

technical field [0001] The present invention relates to discharge lamps, in particular to electrodeless induction discharge lamps. Background technique [0002] Such a discharge lamp is known from Chinese Patent No. 96191079.8. This kind of discharge lamp comprises: an electrodeless discharge chamber, which includes a tubular lamp housing filled with mercury and an inert gas. The lamp housing includes two parallel tubes. The side tubes are connected, and are connected with the second side tube at or near the other end of the parallel tube to form a closed loop; surround the first magnetic core placed on the first side tube of the lamp housing; surround the A second magnetic core placed on the second side tube of the lamp housing; first and second induction coils respectively arranged on the first and second magnetic cores; coupled to the first and second induction coils a high-frequency power supply for supplying sufficient high-frequency energy to said mercury vapor and s...
