Abstract

A superpower LED down lamp belongs to the field of LED luminaire, comprising a shell, a radiator in the shell and an LED light source; wherein, the upper part of the shell is equipped with a reflector and a light-passing board, the lower part of the shell is equipped with a driving power, and the shell is sealed by a cover board; the radiating substrate of the radiator is in cylinder shape, a plurality of radiating fins are evenly distributed on the cylinder-shaped radiating substrate, a radiating base with a superpower LED light source is arranged in the center in the cylinder-shaped radiating substrate, the radiating base and the radiating substrate are connected by a plurality of radiating ribs, the structure of the radiator is improved to increase the radiating area, so as to accelerate the radiating speed, so that the requirement of LED light source on radiating is satisfied and the service life is prolonged, and the volume of the radiator is small and the manufacturing cost of the luminaire is low.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to a high-power LED downlight. Background technique [0002] LED (light emijjing diode) has the advantages of long life, high luminous efficiency, no radiation, low power consumption, etc. It is an energy-saving and environmentally friendly product; high-power LED adopts integrated packaging technology, with higher luminous efficiency, greater power, and small size, so it Power LED lamps are also emerging. [0003] The light sources used in the existing LED downlight lamps are traditional ordinary light bulbs or energy-saving light bulbs. This traditional light source has the disadvantages of high power consumption, high temperature, poor safety performance, unsatisfactory light effect and short life. The high-power LED light source is a green and environmentally friendly light source, which is more and more accepted and valued by people. Contents of the invention [0004] The present ...
