Abstract

The utility model discloses a radiator of an LED down lamp, which is characterized in that the radiator comprises a column-shaped body which is provided with a plurality of longitudinal capillary column-shaped holes which are distributed in a cellular shape, a heating converting device, namely an LED chip, is arranged at an air inlet at the bottom of the radiator, and the bottom of the radiator is provided with a long straight radiating channel. The radiator of the LED down lamp radiates through free convection, and is additionally provided with the radiating channel through transformation so as to form wind tunnel radiation, therefore, the heat quality of the light given out by the LED can be effectively guaranteed to be rapidly extracted into the air from the channel, the temperature is lowered, the service life of the LED is prolonged, the light efficiency is improved and the light attenuation is reduced.

Description

A kind of LED Down lamp radiator
Technical field
The utility model relates to a kind of LED Down lamp radiator, is a kind of good heat dissipation effect, raising LED life-span, the unique LED Down lamp radiator of outward appearance specifically.
Background technology
Because the LED of white light succeeds in developing, LED begins to enter into illuminating industry.LED belongs to cold light source; Compare with fluorescent lamp with white trifoliate orange lamp, it has long, the shock-resistant advantage such as fragmentation that promptly is difficult in power and energy saving, life-span, compares with fluorescent lamp; Do not glimmer in addition, toggle speed is fast, the advantage of environmentally safe, is regarded as perfect light source of new generation by the photoelectricity industry.Though LED is regarded as cold light source, still can produce certain heat during work, the operating temperature of LED generally should be less than 50 degree.Existing LED Down lamp radiator exist radiating effect bad, influence LED service life, shortcoming that outward appearance is general.
Summary of the invention
The purpose of the utility model provides a kind of good heat dissipation effect, raising LED life-span, the unique LED Down lamp radiator of outward appearance.
The purpose of the utility model realizes through following technical scheme.
A kind of LED Down lamp radiator, it is characterized in that: said radiator comprises column, column is provided with some vertical capillary cylinder holes.
Said capillary cylinder hole is cellular distribution.
The bottom air inlet mouth place of said radiator is provided with heating conversion equipment led chip.
The bottom of said radiator is provided with straight microscler heat dissipation channel.
The utility model compared with prior art has the following advantages.
The utility model LED Down lamp radiator is when utilizing Natural Heat Convection; Increase the heat radiation of heat dissipation channel formation wind tunnel type through transforming; Guaranteed that effectively the luminous heat of LED is retracted to air fast from passage, reduced temperature, improved life-span, light efficiency and the minimizing light decay of LED.
Description of drawings
Fig. 1 is the front view of the utility model LED Down lamp radiator.
The specific embodiment
Below in conjunction with accompanying drawing the utility model LED Down lamp radiator is described in further detail.
As shown in Figure 1, the described LED Down lamp of the utility model radiator comprises column 1, and column is provided with some vertical capillary cylinder holes 2.The capillary cylinder hole is cellular distribution.The bottom air inlet mouth place of radiator is provided with heating conversion equipment led chip.The bottom of radiator is provided with straight microscler heat dissipation channel.The utility model LED Down lamp radiator is when utilizing Natural Heat Convection; Increase the heat radiation of heat dissipation channel formation wind tunnel type through transforming; Guaranteed that effectively the luminous heat of LED is retracted to air fast from passage, reduced temperature, improved life-span, light efficiency and the minimizing light decay of LED.
