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.

Example Embodiment

[0024] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0025] See figure 1 , Is a profile heat sink for LED lamps of the present invention, which is an aluminum alloy profile. This embodiment adopts aluminum alloy profiles, which can greatly reduce the production cost of the radiator, but the technical solution of the present invention is not limited to this, and aluminum, copper or aluminum-magnesium alloy profiles can also be used.

[0026] In this embodiment, longitudinally extending heat dissipation teeth are provided on both sides of the front surface of the substrate and the back surface of the substrate. Among them, the longitudinal symmetry axis on the back of the base plate 1 is provided with a longitudinally extending circular mounting hole 3, the hole slot type K is used to install various fixing parts or brackets; the height profile of the heat dissipation teeth 2 on both sides of the base plate ...

Abstract

The invention discloses a sectional material heat radiator for an LED (Light Emitting Diode) lamp. Heat radiating teeth longitudinally extending are arranged at the two sides of the front of a base plate and on the back of the base plate, and a light source of the LED lamp is arranged in the center of the front surface of the base plate. The length of the sectional material heat radiator can be conveniently determined according to heat radiating requirements, the heat radiating modular design of an LED lamp casing is truly met, the series design of the LED lamp is greatly accelerated, the production cost of the lamp is lowered, and the lamp has more strong adaptability and competitiveness.

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...
