Abstract
The invention discloses a fan-based high-power LED (light-emitting diode) street lamp cooling component which comprises a substrate radiator (1) and a power supply radiator (2), wherein finned radiators are respectively adopted as the substrate radiator and the power supply radiator; a cooling fan (4) is fixedly arranged on the substrate radiator (1); two air inlets (6) are respectively and symmetrically formed in a lamp shade (5) at the two sides of the cooling fan (4); an air outlet (7) is formed in the lamp shade (5) above the power supply radiator (2); a sealing sleeve (8) is arranged between the air inlets (6) and the cooling fan (4). According to the cooling component, the military industry level cooling fan is adopted, so that work stability of the cooling fan is guaranteed, and the service life of the cooling fan is long; the sealing sleeve is arranged between the air inlets and the cooling fan, so that the cold air of the outside can be introduced into the cooling fan from the two air inlets, and the hot air is discharged outside through the air outlet; a clear airflow channel is formed in the whole cooling process, and countercurrent and crosstalk are not caused between the cold air and the hot air, so that the cooling effect is guaranteed.
Description
Technical field
The present invention relates to high-powered LED lamp field, particularly relate to a kind of high-power LED street lamp radiating subassembly based on fan.
Background technology
Under the guide of the strategy of sustainable development, energy-saving and emission-reduction thought is constantly promoted, current country more and more payes attention to lighting energy saving and environmental issue, carrying out energetically using LED bulb, along with the development of LED technology, electricity-saving lamp and incandescent lamp will be replaced by LED in the near future, and LED street lamp has extraordinary application prospect in new city illumination.
In the realization of high-powered LED lamp, high-power lamp pearl can reach 1W, 2W, even tens of watts, operating current can be tens milliamperes to hundreds of milliampere not etc., therefore the lamp pearl of high-powered LED lamp realizes not having problems.And for high-powered LED lamp, power can be accomplished much, its bottleneck is the design of radiator structure, if can realize LED street lamp internal base plate and the good heat radiation of power supply, just can realize more high-power LED lamp.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of novel high-power LED street lamp radiating subassembly based on fan is provided, at substrate and power supply place, finned radiator is set respectively, ensure the heat radiation of substrate and power supply; In heating, substrate place the most serious adds fan, strengthens the air circulation in lampshade further, improves radiating efficiency.
The object of the invention is to be achieved through the following technical solutions: based on the high-power LED street lamp radiating subassembly of fan, be arranged in the lampshade of high-power LED street lamp, it comprises baseplate heat sink and power-supply radiator, baseplate heat sink is fixedly mounted on the substrate of LED street lamp, and power-supply radiator is fixedly mounted on the power supply of LED street lamp; Baseplate heat sink and power-supply radiator all adopt finned radiator, and baseplate heat sink is installed with radiator fan, and the lampshade of radiator fan both sides is symmetrically arranged with air inlet, and the lampshade above power-supply radiator is provided with exhaust outlet.
As a modification of the present invention, in described air inlet and exhaust outlet, be provided with screen pack.
Improve as another kind of the present invention, between described air inlet and radiator fan, be provided with sealing shroud.
The invention has the beneficial effects as follows:
1) at substrate and power supply place, finned radiator is set respectively, ensure that the heat radiation of substrate and power supply;
2) add radiator fan at heating substrate place the most serious, further enhancing the air circulation in lampshade, improve radiating efficiency;
3) adopt military project level radiator fan, ensure that radiator fan job stability, long service life; For LED street lamp, the service life of lamp pearl, drive circuit and power supply is not all a problem, generally needing repairing, what change is exactly radiator fan, and after adopting military project level radiator fan, service life of whole LED street lamp and job stability obtain lifting to a great extent;
4) be provided with screen pack in air inlet and exhaust outlet, can prevent mosquito, paper scrap etc. from entering in lampshade the air circulation blocked in lampshade;
5) sealing shroud is provided with between air inlet and radiator fan, guarantee that the wind (air intake of whole street lamp) that radiator fan is inhaled is the extraneous cold wind entered from two air inlets, extraneous cold wind takes away the temperature on fin after blowing over the fin on baseplate heat sink, play cooling heat dissipation effect, hot blast after baseplate heat sink fin is blown in radiator fan, the fin flowing through power-supply radiator again cools power-supply radiator fin, and the vent of final thermal current above power supply is discharged; Whole cooling procedure forms a gas channel clearly, between cold wind and hot blast can not adverse current, crosstalk, ensure that cooling heat dissipation effect.
