Abstract

The invention discloses an LED (light emitting diode) radiating illumination device which comprises LED light sources, a substrate and a radiator, wherein the LED light sources are a plurality of efficient LEDs packaged individually and are arranged on the front end face of the substrate; the substrate is made from high conduction materials, the rear end face of the substrate is provided with a radiator, the heat conductivity is more than 3W / mk; and the radiator is a sunflower radiator. Compared with the prior art, according to the structure provided by the invention, because the natural radiating method of radiating sunflower is adopted, the noise problem is solved thoroughly, the plurality of LEDs which are packaged individually are adopted for the LED light sources, and a red light LED is added, the LEDs in the center of the light sources are overdriven, the LEDs at the periphery are low-driven, the illumination effect of the LEDs is improved greatly, the high heat conduction substrate with heat conductivity greater than 3W / mk is adopted, and the LED heat conduction is improved.

Description

technical field [0001] The invention relates to a lighting device, which is widely applicable to floodlights, patio lights, floodlights, studio lights, focusing lights, etc., and particularly refers to a LED heat dissipation lighting device. Background technique [0002] In the past, the light sources used in traditional studio lights, floodlights, floodlights, etc. were mainly halogen lamps, metal halide lamps, etc., and these light sources would produce radiation such as ultraviolet rays, infrared rays, and far infrared rays. The face of the announcer, while floodlights, floodlights, etc. are also facing the crowd for a long time, so that a large amount of heat radiation generated by the light source may cause skin cancer. [0003] LED light source has been widely used as a green and pollution-free energy-saving light source. The LED light source currently used in the market, such as: Chinese utility model patent No. ZL 200820233726.X, named "variable focus LED film and te...
