Abstract
The invention discloses a micro air duct radiating light emitting diode (LED) street lamp, which comprises a lampshade, an LED chip, a radiating pedestal, micro air duct grids, a radiating shell, an electric box and supporting posts, and is characterized in that: the LED chip is tightly attached to the radiating pedestal, the radiating shell and the radiating pedestal are fixedly connected with the micro air duct grids through the supporting posts, and a control circuit is arranged in the electric box, and is connected with the LED chip by a lead. The LED street lamp has the advantages that: the micro air duct grids are used for radiating, so that over-high temperature rise of the LED chip is prevented, the LED chip is difficult to damage due to high temperature, and the service life of the lamp is prolonged; and the lamp is easy to manufacture, install, produce and operate.
Description
Technical field
The present invention relates to the LED street lamp, the LED street lamp of especially a kind of gentle breeze road heat radiation.
Background technology
Existing LED street lamp because heating is very big at work, will produce thermal shock to it, if heat in time is not dispersed into the external world, will cause the led chip temperature to raise, and at high temperature work, often chip failure.For increasing the reliability of work, design radiator to chip cooling.The radiator of existing LED street lamp for improving radiating effect, generally is the surface radiating that utilizes lamp outer casing; But there is the adiabatic amount of free air bound to transmit at the heat-radiating substrate of led chip and the shell of light fixture; Radiating effect can decline to a great extent, and causes the LED street lamp to descend service life, even burns.
Summary of the invention
Technical problem to be solved by this invention provides the LED street lamp of a kind of gentle breeze road heat radiation, has good performance of heat dissipation.
Technical scheme of the present invention is:
The LED street lamp of a kind of gentle breeze road heat radiation; Comprise lampshade, led chip, cooling base, gentle breeze road grid, heat-dissipating casing, electrical box, support column; Described led chip is close on the cooling base; Described heat-dissipating casing is fixedly connected with gentle breeze road grid through support column with cooling base, in the described electrical box control circuit is installed, and control circuit utilizes lead to be connected with led chip.
Described cooling base and heat-dissipating casing all adopt copper or aluminium to process.
The material of described gentle breeze road grid adopts wide aluminium foil or the Copper Foil of 3 ~ 5mm, one deck horizontally-arranged, and the vertical row of one deck has a common boundary and forms, and gentle breeze road clathrum is fixedly connected with the layer material contact position.
Basic principle of the present invention: adopt above-mentioned scheme; Heat-dissipating casing is connected through gentle breeze road grid with cooling base; The air flow channel and the environmental communication that form in the gentle breeze road grid, when the LED street lamp was worked, temperature raise; Heat spills in the environment after importing heat-dissipating casing and gentle breeze road grid air through gentle breeze road grid, and it is too fast to prevent that the led chip temperature from rising.
Beneficial effect of the present invention is:
(1) utilize the grid heat radiation of gentle breeze road, it is too fast to prevent that the led chip temperature from rising, and led chip is difficult for Yin Gaowen and damages the long service life of lamp.
(2) make and install simply, be easy to production operation.
Description of drawings
Fig. 1 is a sketch map of the present invention.
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1, lampshade 2, led chip 3, cooling base 4, gentle breeze road grid 5, heat-dissipating casing 6, electrical box 7, support column.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2 the specific embodiment of the invention is further described:
According to technical scheme provided by the invention; The LED street lamp of a kind of gentle breeze road heat radiation; Comprise lampshade 1, led chip 2, cooling base 3, gentle breeze road grid 4, heat-dissipating casing 5, electrical box 6, support column 7, described led chip 2 is close on the cooling base 3, and described heat-dissipating casing 5 is fixedly connected with gentle breeze road grid 4 through support column 7 with cooling base 3; In the described electrical box 6 control circuit is installed, control circuit utilizes lead to be connected with led chip 2.
Described cooling base 3 all adopts copper or aluminium to process with heat-dissipating casing 5.
The material of described gentle breeze road grid 4 adopts wide aluminium foil or the Copper Foil of 3 ~ 5mm, one deck horizontally-arranged, and the vertical row of one deck has a common boundary and forms, and 4 layers of gentle breeze road grids are fixedly connected with the layer material contact position.
Basic principle of the present invention: adopt above-mentioned scheme; Heat-dissipating casing 5 is connected through gentle breeze road grid 4 with cooling base 3; The air flow channel and the environmental communication that form in the gentle breeze road grid 4, when the LED street lamp was worked, temperature raise; Heat spills in the environment after importing the air in heat-dissipating casings 5 and the gentle breeze road grid 5 through gentle breeze road grid 4, and it is too fast to prevent that led chip 2 temperature from rising.
Beneficial effect of the present invention is: utilize 4 heat radiations of gentle breeze road grid, it is too fast to prevent that led chip 2 temperature from rising, and led chip 2 is difficult for Yin Gaowen and damages the long service life of lamp; Make and install simply, be easy to production operation.
