Abstract
The utility model discloses an LED illuminating device having an excellent radiating property and solves the problem of the traditional LED illuminating device that the inferior radiating property results in shortened service life of the illuminating device and even damaged illuminating device. The LED illuminating device having an excellent radiating property comprises a lampshade, an LED light source, an LED driving power supply, a radiating aluminum element and an electrical equipment box, wherein the bottom of the radiating aluminum element is provided with an air vent; a small air chamber is arranged above the radiating aluminum element; and a fan is arranged in the small air chamber. The LED illuminating device is fit for solving the problem of high-power LED miner lamp.
Description
Technical field
The utility model relates to lighting device, relates in particular to a kind of LED lighting device with excellent heat dispersion performance.
Background technology
High-powered LED lamp in the market exists the dissatisfactory problem of heat radiation, and the quality of heat radiation is directly connected to the life-span of high-power LED light source.The heat radiation of general high-powered LED lamp is a passive type, and method reaches the heat radiation purpose for directly adorning an aluminum alloy sheet conduction heat.So often influence the life-span of high power light source.The normal operation circumstances temperature model of led light source is that (31-60) degree centigrade, temperature surpasses the life-span that will have influence on light source greatly, surpasses more than 10 watts with integrated LED light source, and the heat radiation requirement is higher.The general temperature scope that all surpasses working environment of heat dissipating method in the market reaches more than 60 degree, thereby has influence on the operate as normal of led light source.
Summary of the invention
The utility model has solved the problems referred to above of the prior art, and the device that is provided has good performance of heat dissipation, thereby and can adapt to different working environments by the speed of automatic control heat radiation.
The technical solution adopted in the utility model is:
A kind of LED lighting device with excellent heat dispersion performance, comprise lamp bracket, lampshade, led light source, LED power supply, heat radiation aluminum component and electric appliance box, it is characterized in that: on the heat radiation aluminum component inwall of the blade bottom that is positioned at described heat radiation aluminum component, be equipped with air vent, little wind room also is housed above described heat radiation aluminum component, and little wind is equipped with electric fan in the room.
Aforesaid LED lighting device with excellent heat dispersion performance, it is characterized in that: described electric fan has another fan power, and is controlled by the intelligent temperature detection control circuit board that can start or close fan under design temperature automatically.
Aforesaid LED lighting device with excellent heat dispersion performance is characterized in that: the circuit design temperature on the described circuit board is 60 degrees centigrade.
Have the LED lighting device of excellent heat dispersion performance as mentioned above, it is characterized in that, described air vent is 6-8, and is distribution symmetrically and evenly.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a heat radiation aluminum component structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, described LED lighting device with excellent heat dispersion performance comprises lamp bracket 1, lampshade 2, led light source 3, LED driving power 4, heat radiation aluminum component 5 and electric appliance box 6, on the heat radiation aluminum component inwall 7 of the blade bottom that is positioned at described heat radiation aluminum component 5, be equipped with 4 air vents 12, little wind room 8 is housed above described heat radiation aluminum component, little wind is equipped with electric fan 9 in the room, electric fan 9 has another electric fan driving power 11, and controlled by the intelligent temperature detection control circuit board (10) that under design temperature, can start or close fan automatically.When led light source was worked, the air vent 12 on described heat radiation aluminum component 5 inwalls 7 can be accelerated heat radiation because stack effect plays the ventilation guide functions; Simultaneously, the automatic control circuit on the circuit board 10 is set in 60 degrees centigrade, and when the temperature in the lampshade reached 60 degrees centigrade, described automatic control circuit can start small fan 9, thereby can faster heat radiation, keep the led light source environment temperature 60 Celsius more than.Fig. 2 has shown the structure of heat radiation aluminum component, has reflected the situation of the air vent 12 on the inwall 7 of heat radiation aluminum component 5.
The utility model compared with prior art has following good effect:
1, rational in infrastructure, compactness;
2, owing to adopt multiple radiating mode, its better heat-radiation effect;
3, owing to adopting automatic control circuit, can energy savings.
