Abstract

The invention discloses a high-power 360 degree LED bulb using COB packaging with heat dissipation. The inner wall of a heat dissipation transparent cover (1) is vertically and evenly provided with a plurality of lamp piece grooves (4) in a distribution mode, each lamp piece groove (4) is inserted with an LED lamp piece (5) to make the corresponding LED lamp piece (5) be tightly attached to the inner wall of the heat dissipation transparent cover (1),a circuit board (6) is connected at the bottoms of the LED lamp pieces (5), a base (2) is internally provided with an embedded heat dissipation tube (8),the upper part and the lower part of the embedded heat dissipation tube (8) are openings, a power driver (9) is arranged between the circuit board (6) and a standard lamp screw base (3),after the power driver (9) extends into the embedded heat dissipation pipe (8), the middle part of the power driver (9) is located in the embedded heat dissipation pipe (8), and the lower part of the power driver (9) penetrates through the embedded heat dissipation pipe (8) and enters into the standard lamp screw base (3).

Description

technical field [0001] The present invention relates to a high-power 360° LED bulb with COB package and heat dissipation, in particular to a 6W / 10W 360° LED bulb. Background technique [0002] Most of the 6W / 10W light sources on the market or the heat dissipation structure of light bulbs, bulbs and other lamps, these high-power light bulbs are mostly SMD LED light sources, and the heat dissipation only relies on one-sided heat dissipation of the substrate and air heat dissipation, but this heat dissipation structure The heat dissipation efficiency of the LED lamp is low, the heat dissipation effect is extremely unsatisfactory, and the light bulb lamp is very easy to heat up. In view of the blue light chip technology, insufficient heat dissipation will cause heat exhaustion of the LED lamp, affecting the service life; insufficient heat conduction will cause heat accumulation. And it ultimately limits the release and diffusion of LED light, and the use of silica gel system is ...
