Abstract
The utility model provides a respiration heat radiation device of a high-power LED lamp, which is characterized in that a cavity with both an upper filter screen and a lower filter screen is arranged in the housing of the device, activated charcoal substance is arranged inside the cavity, an upper cover is mounted at the upper part of the housing of the device, an air conducting cavity is formed above the upper filter screen of the upper cover, and conducting holes are formed on the upper cover. The respiration heat radiation device realizes automatic circulation of cold air and hot air in the cavity of the lamp, so as to lower the temperature in the cavity of the lamp and solve the heat radiation problem of the high-power LED lamp.
Description
Technical field
The utility model relates to the LED lamp heat-radiating device, especially a kind of high-power LED lamp respiratory heat loss device.
Background technology
With regard to the LED illumination, global many mechanisms are all in the heat sink material of studying light fixture and structure at present.What adopt is fin heat abstractor in the collocation of the back side to domestic led light source general on the structure of array, and LED power is as improve again, the heat radiation that just improves light source and light fixture with forced-ventilated heat radiation that has.Adopt the weak point of fin heat abstractor scheme to be on the led array formula structure: the non-ferrous metal of employing is too much, and the Unit Weight of light fixture is heavier, and radiating effect is not good; Adopting forced-ventilated heat sink conception, is the motor that air draft is installed in lamp interior, and weak point is the service life of the life-span of motor well below LED, and motor is not as moving, and LED will lose function very soon.The most important link of high-power LED lamp heat abstractor is a heat dissipation problem, how to take new technical scheme, rationally, scientifically reduces the temperature rise of lamp holder, and the continuity life of product is the key of dealing with problems.
Summary of the invention
The purpose of the utility model is to propose a kind of high-power LED lamp respiratory heat loss device, and it can realize the circulation voluntarily of hot cold air in the lamp chamber, reduces the temperature in the lamp chamber.
The technical scheme that the utility model adopts is: a kind of high-power LED lamp respiratory heat loss device; It is characterized in that in device case, being provided with a cavity with upper and lower filter screen; Cavity is built-in with the activated carbon material, and loam cake is equipped with on device case top, on be covered with via.
Said loam cake forms air conducting chamber above upper filter screen, air conducting chamber periphery offers via.
The lid of said loam cake offers via along periphery.
The outer surface of said device case and loam cake is provided with fin.
The beneficial effect and the characteristics of the utility model are: 1. adopted this brand-new technology structure of respiratory heat loss device; Device case is combined to be installed on the LED lighting through silicon rubber, heat-conducting cream; Realized that the hot cold air in the lamp chamber circulates voluntarily; Reduce the temperature in the lamp chamber, solved the high-power LED lamp heat dissipation problem.2. set up defences in the respiratory heat loss device case rust filter screen protection activated carbon material and location utilize the activated carbon material to play dustproof, waterproof, the effect of purifying air, and make unimpededly convection circulation of air.3. in respiratory heat loss device loam cake, form air conducting chamber and via, make integral body form complete waterproof and dustproof, aeration radiation system, it is simple in structure, and is reasonable in design, has long-life, non-maintaining characteristics.
Description of drawings
Fig. 1 is the structural representation of one of the utility model embodiment;
Fig. 2 is the principle schematic that the utility model is used for the light fixture heat radiation.
Label is represented respectively among the figure: 1-light fixture, 2-device case, 3-lower filter screen, 4-activated carbon material, 5-upper filter screen, 6-loam cake, 7-via, 8-air conducting chamber, 9-via, 10-LED die set light source, 11-fin radiator.
The specific embodiment
Shown in Fig. 1 embodiment, high-power LED lamp respiratory heat loss device is provided with the cavity of a band upper filter screen 5 and lower filter screen 3 in device case 2, and filter screen adopts antirust filter screen; Cavity is built-in with activated carbon material 4; Loam cake 6 is equipped with on device case 2 tops, and loam cake 6 is provided with several vias, and wherein: loam cake 6 forms air conducting chamber 8 above upper filter screen 5; Air conducting chamber 8 peripheries offer via 7; The lid of loam cake 6 offers via 9 along periphery, and device is installed on the light fixture 1, the flow direction when arrow indicates air exchange among the figure.Outer surface at device case 2 and loam cake 6 is provided with fin, with the heat dispersion of further raising device case 2.During light fixture used, the external and internal pressure that the hot cold air alternation that light fixture is 1 inside and outside is produced was poor, and the hot-air in the light fixture 1 is exchanged with outdoor cold air through antirust filter screen and activated carbon material 4 automatically, reached the effect of ventilation and heat.
Fig. 2 illustrates principle and the embodiment that the utility model is used for the light fixture heat radiation, can the utility model device be installed on all kinds of LED lightings 1, and its installation method can adopt silicon rubber, heat-conducting cream to combine, and sealing is reliable.Device multicore sheet integrated packaged high-power LED die set light source 10 in this routine light fixture 1, device has fin radiator 11 on light fixture 1.Except by 11 heat radiations of the fin radiator on the light fixture 1, shown in arrow among the figure, then discharge through the respiratory heat loss device that is installed on the light fixture 1 by wherein a part of heat in light fixture 1 for the heat that light source produces.
Claims (4)
