Universal LED energy-saving illumination lamp

Abstract

A universal LED energy-saving illumination lamp consists of a lamp cap, a lamp shade, a printing circuit and a plurality of light emitting diodes (LED) welded on the printing circuit board, wherein the lamp cap is a screw or bayonet cap; the printing circuit board is arranged in the lamp shade; an alternating current power supply input circuit, a resistance drop-voltage current limiting circuit, a semi-wave rectification filter circuit and a power output circuit are arranged on the printing circuit board; and a plurality of light emitting diodes (LED) are welded on the output circuit. As each light emitting diode (LED) only consumes a few milliamps of electricity and has great brightness, small volume, long service life and vibration resistance, by reasonably selecting filtering capacitance and the number of the light emitting diodes (LED), adequate brightness can be achieved, electric energy is greatly saved and the electric expenditure is reduced; the lamp cap, which can be made into screw or bayonet cap, can be matched with the prior universal alternating current lamp cap; therefore, the universal LED energy-saving illumination lamp is suitable to be used as illumination lamps or reflector lamps in family, government organizations, hotels, leisure places, schools, and the like.

Description

【Technical field】 [0001] The invention relates to an illuminating lamp, in particular to a general-purpose energy-saving LED illuminating lamp. 【Background technique】 [0002] At present, urban and rural residents across the country generally use electricity for lighting, and most of the lighting sources still use incandescent bulbs. In order to save electricity, a few areas and residents use relatively energy-saving energy-saving lamps, but they still need to consume a lot of electricity. In order to save electricity, the government has adopted a variety of incentives. On the one hand, researchers are encouraged to develop new energy-saving lights; Complicated, high cost of materials, resulting in expensive prices, the general population is still reluctant to buy and use. Relevant government departments and the majority of residents are eager to have a light source with less power consumption, good lighting effect, easy to use, and cheap price on the market. 【Content of ...
