Abstract

The invention discloses a general power adjustor for illuminating lamp. The general power adjustor consists of a TOPSwitch-II TOP22XY series three-terminal power supply chip launched by Power Integration Inc from U.S. and peripheral circuits thereof. The general power adjustor can transform alternating commercial current with the voltage of 220V into direct current with the voltage of about 300V to be output, the transforming efficiency is as high as more than 90 percent, and the general power adjustor has the advantages of large output power range, low cost, high integration degree, simple circuit design, etc. In concrete form, the general power adjustor can be made into a power adjustor which can adjust continuously and also can be made into a selective multi-voltage grade output power adjustor, and the power adjustor can be widely used for the power adjustment of the illuminating lamps including a filament lamp, an energy saving lamp and a daylight lamp.

Description

technical field [0001] The invention relates to a general power regulator for illuminating lamps, belonging to the field of switching power supplies. Background technique [0002] With the steady advancement of the national energy saving and emission reduction policy, the power regulators of lighting lamps are more and more popular from desk lamps to general lighting fixtures. , its output is alternating current, which can only be used for power regulation of incandescent lamps, but not for power regulation of energy-saving lamps and fluorescent lamps. To achieve high power, the current domestic lighting power regulators cannot be popularized and applied. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a universal power regulator for lighting fixtures with low cost, stable performance, wide application range and energy saving. [0004] The technical solution adopted by the present invention to solv...
