Abstract
A cooling system of a light emitting diode (LED) imaging lamp comprises a lamp shell, a radiator and a cooling fan, wherein the radiator and the cooling fan are arranged in the lamp shell. A plurality of heat dissipation fins in parallel are arranged at the back of the radiator, the cooling fan is installed on the fins, heat dissipation air flues are formed between adjacent heat dissipation fins, and a plurality of head dissipation holes are formed in the lamp shell and the radiator. The heat dissipation air flues correspond to the heat dissipation holes and an air inlet hole is formed in the rear end of the lamp shell. When the cooling system works, the cooling fan sucks air into the lamp shell from the air inlet hole in the rear end of the shell, the cold air is sucked to the heat dissipation air flues of the radiator by the fan so as to carry out heat exchange, heat quantity of the radiator is taken away, and finally the air is blown to the heat dissipation holes on the side face of the lamp shell by the cooling fan. Therefore, the hot air is taken out of the lamp shell. According to the cooling system of the LED imaging lamp, the air course is shorter so as to be favorable for rapid head dissipation of the heat quantity and the heat dissipation effect is obvious.
Description
Technical field
The utility model relates to LED imaging light fixture, especially a kind of LED imaging luminaire heat dissipating system.
Background technology
As everyone knows, even if the LED light fixture has many characteristics more superior than ordinary incandescent lamp, but up to now, still there is an insoluble problem in the LED light fixture, and that is exactly heat dissipation problem.The LED light fixture time can send amount of heat in work, if the untimely heat radiation of this part heat can have a strong impact on working life and the light efficiency of led chip.Therefore, how better to design the developing direction that the LED luminaire heat dissipating system becomes current LED light fixture.The cooling system of existing LED light fixture generally comprises radiator and radiator fan, radiator and radiator fan are located in the lamp casing, radiator is located at the centre position that light fixture can be inner, the rear end of lamp casing is provided with air inlet, the front end of lamp casing is connected with bulb socket, and bulb socket is provided with air outlet.During cooling system work, radiator fan sucks in wind from the lamp casing rear end, take hot blast out of the external world from bulb socket by radiator, thereby arrives the purpose of heat radiation.There are two larger defectives in above-mentioned cooling system: the first, wind path is from the lamp casing rear end to the radiating shell front end, and wind path is longer, is unfavorable for the Quick diffusing of heat, so its radiating effect is not obvious.In addition, when radiator fan blew out hot blast, because distance is far away, the hot blast of this part might spin in lamp casing and not go, and has a strong impact on its heat radiation.The second, owing to need to set out the air port at bulb socket, dust is easy to enter in the light fixture by this air outlet, affects light extraction efficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED imaging luminaire heat dissipating system, because the heat radiation wind path is shorter, so radiating effect is remarkable.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED imaging luminaire heat dissipating system comprises lamp casing, is located at radiator and radiator fan in the described lamp casing; The described radiator back side is provided with some radiating fins that be arranged in parallel, described radiator fan is installed on the described fin, form heat dissipation wind channel between the adjacent radiating fin, be provided with some louvres with described radiator place on the described lamp casing, described heat dissipation wind channel is corresponding with described louvre; Described lamp casing rear end is provided with fresh air inlet.During cooling system work, radiator fan with wind in the fresh air inlet inspiration lamp casing of lamp casing rear end, the cold wind of this part is drawn onto by fan on the heat dissipation wind channel of radiator and carries out heat exchange, heat on the radiator is taken away, by radiator fan hot blast is blown on the louvre of lamp casing side at last, thereby hot blast is taken out of outside the lamp casing.Because the distance before radiator and the louvre is shorter, hot blast can be discharged outside the lamp casing by louvre rapidly.The utility model wind path becomes shorter, is conducive to the Quick diffusing of heat, and radiating effect is remarkable.In addition, the bulb socket front no longer is provided with air outlet, prevents that dust from entering in the lamp casing.
As improvement, described heat dissipation wind channel is towards the left and right sides of described lamp casing.
As improvement, described lamp casing front end is provided with bulb socket, and described bulb socket is fixedly connected with described lamp casing, and described bulb socket outer surface is provided with groove, and described groove communicates with lamp casing inside.Hot blast in the lamp casing also can be sent outside the lamp casing by the groove on the bulb socket, further accelerates distributing of heat.
The beneficial effect that the utility model compared with prior art brings is:
Because the distance between radiator and the louvre is shorter, hot blast can be discharged outside the lamp casing by louvre rapidly.The utility model wind path becomes shorter, is conducive to the Quick diffusing of heat, and radiating effect is remarkable; In addition, the bulb socket front no longer is provided with air outlet, prevents that dust from entering in the lamp casing.

The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, 2, a kind of LED imaging luminaire heat dissipating system comprises lamp casing 1, bulb socket 2, radiator 6 and radiator fan 7.Described lamp casing 1 is cylindric, and the rear end is provided with bonnet 3, and described bonnet 3 is provided with fresh air inlet (not indicating).As shown in Figure 5, lamp casing 1 front end links to each other with bulb socket 2, also is provided with light source assembly 10 in the described bulb socket 2, and the light source assembly 10 in the bulb socket 2 is fixed on radiator 6 surfaces; Described bulb socket 2 outer surfaces are provided with groove 5, and described groove 5 communicates with lamp casing 1 inside.Shown in Fig. 3,4, described radiator 6 is located at lamp casing 1 general centre position; Described radiator 6 back sides are provided with some radiating fins that be arranged in parallel 9, form heat dissipation wind channel 11 between the adjacent radiating fin 9, and described heat dissipation wind channel 11 is towards the left and right sides of described lamp casing 1; Described radiator fan 7 is fixed on the described radiating fin 9 by installing plate 8.Described lamp casing 1 left and right sides is provided with some louvres that be arranged in parallel 4, and described heat dissipation wind channel 11 is corresponding with described louvre 4, and the end of heat dissipation wind channel 11 is closer apart from louvre 4.
During cooling system work, radiator fan 7 with wind in the fresh air inlet inspiration lamp casing 1 of lamp casing 1 rear end, the cold wind of this part is drawn onto by radiator fan 7 on the heat dissipation wind channel 11 of radiator 6 and carries out heat exchange, heat on the radiator 6 is taken away, by radiator fan 7 hot blast is blown on the louvre 4 of lamp casing 1 side at last, thereby hot blast is taken out of outside the lamp casing 1.Because the distance between radiator 6 and the louvre 4 is shorter, hot blast can be discharged outside the lamp casing 1 by louvre 4 rapidly, and it is shorter that wind path becomes, and is conducive to the Quick diffusing of heat, and radiating effect is remarkable.In addition, bulb socket 2 fronts no longer are provided with air outlet, prevent that dust from entering in the lamp casing 1.
