Embodiment Construction

[0026] figure 1 The first embodiment of an electromagnetic induction low-voltage electrodeless lamp of the present invention is shown. It can be seen from the figure that the electrodeless discharge chamber 1 includes a lamp housing forming a closed circuit 10, the lamp housing contains mercury and an inert gas, and the inner surface of the lamp housing is provided with a fluorescent coating (not shown), and forms a closed circuit 10. There is a double-hole glass tube 2 and a U-shaped single-hole glass tube 3 in the lamp housing of the circuit. The double-hole glass tube 2 is connected to the U-shaped single-hole glass tube at one end 6. The glass tube 3 is sealed and the two glass holes at the end are respectively communicated with the glass holes at both ends of the U-shaped single-hole glass tube. The shell 12 is sealed and connects the two glass holes at this end; a transformer core 7 provided with an input coil 8 is arranged around the single-hole glass tube 3, and the t...

Abstract

The invention provides an electromagnetic induction low-voltage electrodeless lamp, comprising an electrodeless discharging chamber (1) which comprises a lamp shell that forms a closed circuit and is internally provided with ionisable filling matter; the internal surface of the lamp shell is provided with a fluorescent coating layer; furthermore, the lamp shell which forms the closed circuit is internally provided with at least one section of dual-hole typed glass pipe (2) and at least one section of single-hole typed glass pipe (3); the electromagnetic induction low-voltage electrodeless lamp also comprises at least one transformer magnetic core (7) which is provided with an input winding (8) and arranged by surrounding the single-hole typed glass pipe, and a high-frequency power (9) which is connected with the input winding (8) and used for supplying high frequency energy. The electromagnetic induction low-voltage electrodeless lamp has compact structure and beautiful integration.

Description

technical field [0001] The invention relates to a discharge lamp, in particular to an electromagnetic induction low-voltage electrodeless lamp. 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 envelope forming a closed ring, filled with a filling substance such as mercury and an inert gas in the lamp envelope; a transformer core placed around the lamp envelope; an input coil on a transformer core; a high frequency power supply connected to said input coil for supplying sufficient high frequency energy to said mercury vapor and said inert gas to generate a discharge current equal to or Discharge greater than 2A. In this kind of discharge lamp, since the tubular lamp housing constitutes a closed annular electrodeless discharge chamber, it takes up a large space, which is not conducive to the miniaturization of the product an...
