Description
Technical field
The utility model relates to appliance field, particularly a kind of LED radiator.
Background technology
The same with conventional light source, semiconductor light emitting diode (LED) also can produce heat during operation, and how much it depends on overall luminous efficiency.Under powering up energy outside, the radiation recombination generation electroluminescent in electronics and hole, the light radiated near PN junction also needs just can arrive at external world's (air) through the semiconductor medium of chip itself and encapsulation medium, combination current injection efficiency, radioluminescence quantum efficiency, chip exterior light extraction efficiency etc., finally the input electric energy conversion of 30-40% is probably only had to be luminous energy, the energy of all the other 60-70% mainly transforms heat energy with the form of the lattice vibration of non-radiative recombination generation, traditional LED radiator, generally be through ventilating opening directly to dispel the heat, and the circuit of ventilating opening is too straight, be unfavorable for scattering and disappearing of heat.
Utility model content
Technical problem to be solved in the utility model is to provide one, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of LED radiator, comprise radiator body, be made up of shell and ventilation slot, described shell centre is provided with retainer plate and inside is divided into ventilation slot by partition, described ventilation slot is clockwise arc-shaped slot, one end of described arc-shaped slot is connected with described retainer plate, the other end is directly connected with the outer perisotomice of shell, electric power ventilating fan is provided with inside described retainer plate, temperature sensor is provided with in the middle of described LED, described temperature sensor is connected with circuits for triggering, power supply is connected with electric power ventilating fan by circuits for triggering.
Preferably, described electric power ventilating fan be provided with by force, in, weak three gears.
Preferably, the flabellum of described electric power ventilating fan tilts in vertical direction with 45 degree.
Preferably, the notch of described ventilation slot near shell side is greater than the notch near retainer plate side.
Preferably, described electric power ventilating fan upper end is provided with special wiring duct, and described wiring duct is provided with grab.
The beneficial effect of above technical scheme is adopted to be: the ventilation slot of the utility model structure is clockwise arc-shaped slot, one end of described arc-shaped slot is connected with described retainer plate, electric power ventilating fan is provided with inside described retainer plate, when the temperature of LED reaches certain value time, temperature sensor can trigger circuits for triggering automatically, electric power ventilating fan can work, and the hot-air of inside is blown to outside by ventilation slot, and can according to the suitable ventilating fan gear of the thermal creep stress of LED.

Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 and Fig. 3 shows detailed description of the invention of the present utility model: a kind of LED radiator 1, comprise radiator body 1, be made up of shell 2 and ventilation slot 4, described shell 2 centre is provided with retainer plate 5 and inside is divided into ventilation slot 4 by partition 3, described ventilation slot 4 is clockwise arc-shaped slot, one end of described arc-shaped slot is connected with described retainer plate 5, the other end is directly connected with the outer perisotomice of shell 2, electric power ventilating fan 6 is provided with inside described retainer plate 5, temperature sensor is provided with in the middle of described LED, described temperature sensor is connected with circuits for triggering, with described circuits for triggering, power supply is connected with electric power ventilating fan 6, directly dispel the heat because traditional LED radiator is generally through ventilating opening, and the circuit of ventilating opening is too straight, be unfavorable for scattering and disappearing of heat, in the present embodiment, described ventilation slot 4 is clockwise arc-shaped slot, one end of described arc-shaped slot is connected with described retainer plate 5, when ordinary temp, LED can be carried out heat trnasfer by ventilation slot 4 and outside air and then be reached the effect of heat radiation, and when high temperature, it is obviously the effect not reaching heat radiation only by heat trnasfer, so be provided with electric power ventilating fan 6 inside described retainer plate 5, temperature sensor is provided with in the middle of described LED, described temperature sensor is connected with circuits for triggering, when temperature reaches certain height time, described sensor just can trigger circuits for triggering, and circuits for triggering are circuit turn-ons of electric power ventilating fan 6 and then make its work, the hot-air of inside will be blown to outside by such ventilating fan 6, enhance the effect of heat radiation.
It should be noted that, time sometimes LED is in different temperature, we need electric power ventilating fan 6 to have different rotating speeds, so, in the present embodiment, described electric power ventilating fan 6 is provided with by force, in, weak three gears, in the process used, we just can carry out speed governing to ventilating fan 6 as required, when internal temperature is high time, it can be transferred to high tap position by us, and when internal temperature is slightly low time, we can be transferred to low gear, so both save electric energy, have the service life why having added radiator 1.
In addition, the flabellum gradient of described electric power ventilating fan 6 is in vertical direction with 45 degree, the object done like this is, namely hot-air above ventilating fan 6 can be fanned by the flabellum of 45 degree, can laterally be blown to by air inside ventilation slot 4 again, firm different function, the notch of ventilation slot 4 near shell 2 side be greater than the notch near retainer plate 5 side, because half of periphery jin increasing, inside the area of limit, increase inner and extraneous contact area so as far as possible.
Described on base, described electric power ventilating fan 6 upper end is provided with special wiring duct 7, and wiring duct 7 is provided with grab 8, because electric wire may be damaged because of the rotation of flabellum in the side that electric wire is present in electric power ventilating fan 6, so electric wire to be positioned over special wiring duct 7, and the grab 8 that wiring duct 7 is provided with, electric wire is fixed on wiring duct 7 by card ditch 8, prevents it from dropping.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
