A profile radiator for LED lamps

Abstract

The utility model relates to a profile heat sink for LED lamps. Radiating teeth extending longitudinally are arranged on both sides of the front side of the base board and the back side of the base board. The front center of the base board is the installation position of the light source of the LED lamp. The length of the profile radiator can be conveniently determined according to the heat dissipation requirements, and the module design that really meets the heat dissipation of the LED lamp shell greatly speeds up the serial design of LED lamps, reduces the production cost of the lamps, and makes the lamps more adaptable and competitive.

Description

technical field [0001] The invention relates to a profile radiator, in particular to a profile radiator for LED lamps, which is mainly used for LED lamps such as street lamps and garden lamps. Background technique [0002] LED is an electronic device with diode characteristics that can convert electrical energy into light energy. LED lamps have the most promising development prospects in the field of lighting. Their outstanding advantages are: high luminous efficiency, good monochromaticity of light, narrow spectrum, and can directly emit colored visible light without filtering; In effect, the power consumption is one-eighth of that of incandescent bulbs and one-half of that of fluorescent tubes; the service life is long, with an average lifespan of 100,000 hours; safety and reliability are strong, and it is conducive to environmental protection (cold light source has low calorific value, No heat radiation, safe to touch, easy to install and maintain; does not contain mercu...

AI Technical Summary

Problems solved by technology

(3) LED light sources are generally used in embedded lighting fixtures. Only about 15% of the electric energy driving the light source is converted into light energy, and the remaining 85% is converted into heat energy. If this part of heat energy is not exported and dissipated in time, it will cause light source chips. The temperature rises sharply, and the high temperature will lead to the deterioration of the performance of the chip itself and the packaging resin, resulting in a decrease in luminous efficiency, severe light decay and shortened life.

[0007] At present, the deficiencies in the design of the heat dissipation module of the LED lamp shell are mainly manifested in: (1) The universality of the heat dissipation shell of the lamp is poor

Die-cast heat sinks, one design can only be used for one lamp specification, difficult to modify, expensive to open the mold, extremely unfavorable for the development of new products

(2) It is difficult to achieve serialization of lighting products

Serialization of traditional LED lamps is difficult. For example, a 100W lamp can only use a 100W lamp shell radiator, which is highly specific and the cost of serialization is very high.

(3) Limited cooling surface
