The purpose of this utility model can also adopt following technical measures to solve:
As more preferably scheme, described heat dissipating layer is made up of upper and lower multilayer heat sink, is provided with the heat conduction support member between the adjacent heat sink and connects, and also have between the convection current interstitial area between the adjacent heat sink.Above-mentioned multilayer heat sink is formed the heat dissipating layer structure, helps further improving the integral heat sink effect of street lamp.
Described heat conduction support member is the tubular support that Heat Conduction Material is made, and the heat that led module produces to each layer heat sink, is dispersed to spread heat in the air by heat sink by the heat conduction support member again, has improved the radiating effect of led module widely.
According to the principle that heat upwards distributes, described led module is arranged on the bottom of heat dissipating layer, helps improving the heat radiation of heat dissipating layer to led module, and therefore, it is reasonable that this structure more becomes.
The described thermal insulation layer that blocks blocks thermal insulation board by upper and lower multilayer and forms, and adjacent blocking is provided with not heat conduction support member and connects between the thermal insulation board, and adjacent picking up also has interval, heat insulation gap between the block hot plate.Above-mentioned multilayer is blocked the thermal insulation board composition and is blocked insulating layer structure, can prevent effectively further that the heat anti-pass in the external world from passing LED, and damage the defective of LED.
For avoiding extraneous heat to pass to LED by blocking thermal insulation layer, described not heat conduction support member is the tubular support made of Heat Conduction Material not, the heat transmission is got off by support member with the thermal insulation board that blocks on isolated upper strata.
The beneficial effects of the utility model are:
1), LED street lamp of the present utility model, by led module is arranged on the heat dissipating layer, and is provided with on heat dissipating layer top and blocks thermal insulation layer, heat dissipating layer and block and have between interstitial area between the thermal insulation layer; The heat that LED produces at first can distribute by heat dissipating layer, and by between the convection current interstitial area and the cross-ventilation between interstitial area, that is: the cross-ventilation in high-altitude is dispersed into the LED heat in the air, has improved the effect of dispelling the heat effectively again; Moreover solar heat by the cross-ventilation between interval, heat insulation gap and interstitial area, is distributed solar heat by blocking the obstruct of thermal insulation layer again, can prevent extraneous heat effectively, as: LED is passed in the solar heat anti-pass, and damages the defective of LED.
2), LED street lamp of the present utility model, with heat dissipating layer with block thermal insulation layer and be arranged to sandwich construction respectively; That is: heat dissipating layer is gone to upper and lower at interval by the multilayer heat sink and constitutes, and has between the convection current interstitial area between the adjacent heat sink; Block thermal insulation layer and block thermal insulation board by multilayer and go to upper and lower combinations of gaps and constitute, and adjacent blocking there is interval, heat insulation gap between the thermal insulation board; The further improvement of said structure, effect is passed in the anti-pass that more helps improving its radiating effect and intercepting external heat.
