Abstract

The invention relates to the LED illumination technology, in particular to a special heat radiation section material used for an LED illumination device. Different positions have the same cross section along the length direction of the section material. The invention is characterized in that the cross section of the section material consists of a circle, and two concave positions and two convex positions which are arranged on the circumference; the two concave positions are arranged symmetrically along a diameter of the circle, and extend along the length direction of the section material, in order to form two grooves; the two convex positions are arranged symmetrically along a diameter of the circle, and extend along the length direction of the section material, to form two convex ribs; the two concave positions and the two convex positions are arranged in a staggered way in the circumferential direction of the heat conducting wall; the two convex positions also have a thread bottom hole which is arranged in the length direction of the section material. The invention provides an LED daylight lamp special heat radiation section material with good heat conduction effect, and realizes the heat transmission between an LED illuminator as well as a heat radiation element outside a pipe body.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to a special heat dissipation profile for LED lighting devices. Background technique [0002] Fluorescent lamps have been the mainstream of daily lighting technology for decades, and fluorescent lamps bring a lot of convenience to people's work, study and life. However, traditional fluorescent lamps generate a lot of heat while emitting light, so the light output rate is low and the life of the lamp tube is short; in addition, once the lamp tube is broken, it will pollute the environment. In recent years, LED lighting technology has developed rapidly. For example, the Chinese utility model patent document CN2926772Y discloses an LED fluorescent lamp, which includes a lamp tube and mounting heads at both ends of the lamp tube. Each LED tube is electrically connected with a power supply electric control board enclosed in the lamp tube. It installs the luminescent LED tube in the fluorescen...
