Abstract

The invention relates to an easy-radiating high-power light emitting diode (LED) tube lamp, which comprises an aluminum alloy radiating piece, wherein the outer surface of the aluminum alloy radiating piece is provided with a plurality of radiating fins; the plurality of radiating fins are arranged in a parallel strip shape along the axial direction of the aluminum alloy radiating piece; an aluminum base board is arranged on a boss at the inner bottom of the aluminum alloy radiating piece; an LED light source is arranged on the aluminum base board; a circular dot-shaped lens is arranged on the outer side of the LED light source; and a light reflection cup and a bracket are arranged at the front end of the aluminum alloy radiating piece. The LED tube lamp has the advantages of saving electric energy, along with good radiating and illuminating effects, aesthetic appearance and the like and is suitable for indoor and outdoor illumination.

Description

technical field [0001] The invention relates to an LED semiconductor lighting fixture, in particular to an easy-to-dissipate, high-power, embedded LED downlight. Background technique [0002] The downlight is a kind of lighting fixture embedded in the ceiling, the biggest feature is that it can maintain the overall unity and perfection of the architectural decoration, and will not destroy the perfect unity of the ceiling art because of the setting of the lamp. It is widely used in large offices, conference rooms, department stores, supermarkets and specialty stores, laboratories, airports and some residential rooms. [0003] The downlights commonly used at present mostly use incandescent lamps or energy-saving lamps, which have relatively high energy consumption, short life of the lamp tubes, and the light is not soft enough, and the human eyes will directly feel dazzling or even produce glare. With the advancement of electronic technology, lighting fixtures using high-powe...
