Abstract
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...
