Description
Technical field
The utility model relates to a kind of LED illuminating lamp.
Background technology
Some dry environments are as the illuminating lamp on coal mining, construction ground, and because dust is large, temperature is higher, therefore the heat of illuminating lamp often distributes and do not go out, cause that whole illuminating lamp is overheated to be burnt, traditional illuminating lamp weak heat-dissipating, service life is short, anti-dust ability.
Summary of the invention
Technical problem to be solved in the utility model is to provide the LED illuminating lamp that a kind of heat dispersion is better, be applicable to use under adverse circumstances.
The utility model is achieved through the following technical solutions: a kind of LED illuminating lamp, comprise lamp housing, the front end of described lamp housing is provided with LED drive circuit plate, described LED drive circuit plate is provided with LED bulb, in described lamp housing, be provided with a cavity, in this cavity, be provided with an air intake passage and an air-out passage, described air intake passage is connected with air-out passage, between described air intake passage and air-out passage, be " recessed " font, the fixed head of going out to be provided with of described lamp housing, this fixed head is arranged on the exit of air-out passage, the outside of described fixed head is fixed with a fan, described fan is all connected with power supply with LED drive circuit plate, the air inlet place of described air intake passage is provided with a blast pipe, in described blast pipe, be provided with first passage, described first passage is connected with fan mouth.
As preferred technical scheme, described fixed head is inverted "L" shaped, is provided with second channel in fixed head, and described second channel is connected with the air outlet of air-out passage.
As preferred technical scheme, described air-out passage and air intake passage are aluminum material and make.
As preferred technical scheme, between described fixed head and lamp housing, cross the screw and nut installation that removably connects.
The beneficial effects of the utility model are: the utility model is applicable to use under outdoor mal-condition, as the illumination of colliery illumination or some construction grounds, by the radiating mode of reverse-flow type, simple in structure, in the time of the higher or dry environment of temperature, can open fan, start air return and take away lamp housing internal heat, and owing to being the design of reverse-flow type, dust can not enter into lamp housing inside, heat dispersion is better, longer service life.
Brief description of the drawings
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of LED illuminating lamp of the present utility model, comprise lamp housing, the front end of described lamp housing 3 is provided with LED drive circuit plate 2, described LED drive circuit plate 2 is provided with LED bulb 1, in described lamp housing 3, be provided with a cavity, in this cavity, be provided with an air intake passage 5 and an air-out passage 4, described air intake passage 5 is connected with air-out passage 4, between described air intake passage 5 and air-out passage 4, be " recessed " font, the fixed head 6 of going out to be provided with of described lamp housing 3, this fixed head 6 is arranged on the exit of air-out passage 4, the outside of described fixed head 6 is fixed with a fan 9, described fan 9 is all connected with power supply with LED drive circuit plate 2, the air inlet place of described air intake passage 5 is provided with a blast pipe 7, in described blast pipe 7, be provided with first passage 10, described first passage 10 is connected with fan mouth.
As preferred embodiment, fixed head 6 is inverted "L" shaped, is provided with second channel 8 in fixed head 6, and described second channel 8 is connected with the air outlet of air-out passage 4.
In the present embodiment, air-out passage 5 is aluminum material with air intake passage 4 and makes, aluminum material good heat dissipation, and the cold air of coming in from air intake passage can be taken away the heat in outside.
As preferred technical scheme, between described fixed head 6 and lamp housing 3, cross the screw and nut installation that removably connects, be convenient for changing and keep in repair.
Operation principle: starting fan, the air mobile external world is circulated in blast pipe, entered in intake stack by blast pipe again, cold wind in intake stack is taken away the heat of intake stack outer wall, and then pass through again wind pipe, the hot blast of wind pipe through the second channel of fixed head discharged to air in, and then take away the amount of heat in housing, and the design of reverse-flow type makes can not enter in illuminating lamp dust.
The beneficial effects of the utility model are: the utility model is applicable to use under outdoor mal-condition, as the illumination of colliery illumination or some construction grounds, by the radiating mode of reverse-flow type, simple in structure, in the time of the higher or dry environment of temperature, can open fan, start air return and take away lamp housing internal heat, and owing to being the design of reverse-flow type, dust can not enter into lamp housing inside, heat dispersion is better, longer service life.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
