Radiating device for LED lamp and radiator component

Abstract

The invention relates to a radiating device for an LED lamp and a radiator component. The radiator component comprises an arc-shaped plate. The outer arc surface of the arc-shaped plate extends outwards to form a plurality of spaced radiating fins, a connecting groove is arranged at one longitudinal end face of the arc-shaped plate along the longitudinal direction, a connecting convex strip is arranged at the other longitudinal end face of the arc-shaped plate along the longitudinal direction, and at least one heat-conduction pipe installing hole is longitudinally arranged at the upper edge of the arc-shaped plate. The bottom parts of the radiating fins are thick, the top parts are thin, and the convex strips are distributed on the surfaces of the radiating fins. The radiating device comprises a radiator, a heat-conduction piece and at least one heat super-conduction pipe. The radiator is composed of at least one radiator component. One end of the heat super-conduction pipe is inserted into the heat-conduction pipe installing hole on the heat-conduction piece, and the other end is inserted into the heat-conduction pipe installing hole on the radiator component. As the radiating device adopts the modular design, a mould of the radiator is single and the development cost of the mould can be saved. With good radiating effect and light weight, the radiating device can greatly save aluminum materials and reduce the cost.

Description

technical field [0001] The invention relates to a heat dissipation device for an LED lamp for illumination. Background technique [0002] In response to the requirements of the environmental protection era, the requirements for energy-saving and emission-reducing products are getting higher and higher, and the related lighting equipment also has white light due to the invention of LED blue light, and thus becomes a part of lighting, the so-called solid-state lighting (SSL) , The US Department of Energy has the SSL Association. The conversion of the power and luminous flux of a fluorescent lamp is about 15W=490lm~560lm, 20W=700lm~800lm, 30W=1160lm~1400lm, 40W=1700lm~1920lm. The conversion of 220V incandescent bulb power and luminous flux is roughly 10W-65lm, 15W-101lm, 25W-198lm, 40W-340lm, 60W-540lm, 100W-1050lm...etc. At present, the conversion of power and luminous flux of LED white light modules is about 50W-4000lm, 100W-7500lm, and the lower the power, the higher the l...

AI Technical Summary

Problems solved by technology

But no matter how the efficiency is improved, there is a considerable problem, that is, the problem of heat dissipation has not been solved, so that the production of a perfect energy-saving lighting product has stagnated.

Even if there is no problem with heat dissipation, but the light gathering is not good, even if the light is collected by using a light-condensing mirror, the luminous efficiency will be reduced by about 20%.
