Abstract

The utility model discloses an automatic temperature control type forced radiator for an LED high-power lighting lamp, which is invented for solving the problem of poor natural heat dissipation in the prior art. The automatic temperature control type forced radiator is composed of a forced fan, a radiating fin, an automatic temperature controller, an air blocking cover and an air outlet hole. A cold air flow radiating channel is formed, the forced fan is arranged at one end on the radiating fin, the air blocking cover is arranged at the other end on the radiating fin, the automatic temperature controller is arranged in the radiating fin, and an air outlet is arranged at the tail end of a lower lamp shell; and the forced fan, the radiating fin and the air blocking cover are fixed at the upper side of a heat-conduction fixing plate of the lower lamp shell by screws after being combined into a whole. When in electrified lighting in the nighttime, temperature is raised along with time, and the automatic temperature controller can start the forced fan to work when the temperature reaches the set value, so as to blow and cool the radiating fin; when the temperature is reduced to the set value, the automatic temperature controller can stop the fan from working. Therefore, the LED lighting lamp can normally work within the specified temperature range, and the service life is prolonged; with simple structure and low cost, the forced radiator is suitable for the LED high-power lighting lamp.

Description

LED high-power illumination lamp automatic temperature control type forced heat abstractor

Technical field.

The utility model relates to the electronic radiation device, in particular for LED high-power illumination lamp automatic temperature control type forced heat abstractor.

Background technology

The LED high-power illumination lamp that at present domestic each manufacturer produces all is to adopt the cast aluminium shell to wear fin outward, what carry out is the cross-ventilation natural heat dissipation, and for the bigger LED high-power illumination lamp of caloric value, requirement to temperature is the comparison strictness, superhigh temperature work, just may produce light decay, brightness is descended, reduce the life-span, flange-cooled cast aluminium shell is the cost height not only, and in the summer high-temperature environment, work, because of the air themperature height, depend merely on the cross-ventilation natural heat dissipation, LED high-power illumination lamp is to be easy to superhigh temperature work, produce light decay, reduce the life-span.

The utility model content:

In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of simple in structure, with low cost, the LED high-power illumination lamp automatic temperature control type forced heat abstractor of perfect heat-dissipating.

In order to achieve the above object, LED high-power illumination lamp automatic temperature control type forced heat abstractor of the present utility model, by forcing fan, fin, automatic heat regulator, windshield and exhaust vent constitute, and formation cold wind airflow temperature automatic control heat dissipation channel, described pressure fan is established an end that covers on above the fin, windshield covers on the other end above the fin, described automatic heat regulator is contained in the fin, described exhaust vent is arranged on the tail end of lamp lower casing, described pressure fan, fin, windshield, be screwed upside after the automatic heat regulator composition one at the heat conduction fixed head of lamp lower casing, wherein, the air draught end of described pressure fan makes progress, and outlet air end is downward, fixes with screw and fin.

Described further windshield is a dust pan shape, covers on the fin, and tail end is equipped with the LED power supply.

Particularly: described exhaust vent is established the tail end that covers on the lamp lower casing, gets out the aperture of a plurality of air-out, and the filtration silk screen is housed in the described exhaust vent.

Further, scribble heat conductive silica gel between described lamp lower casing heat conduction fixed head and the fin.

Above-mentioned structure, when giving LED high-power illumination lamp energising illumination evening, temperature also can be in time prolongation and rise, when temperature reaches preset value, the closed fan of forcing of automatic heat regulator is started working, the hollow interior cold wind of lamp stand is forced to blow to fin, fin is cooled, cold wind is discharged through exhaust vent after fan housing inwall passage is given the heat radiation of LED driving power once more, when temperature drops to setting value, automatic heat regulator disconnects, fan quits work, and can guarantee LED illuminating lamp operate as normal in the temperature range of setting like this, thereby increase the service life.

This LED high-power illumination lamp automatic temperature control type radiator, simple in structure, cost is low, applied range.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1, the utility model LED high-power illumination lamp with temp autocontrolled forced heat abstractor by forcing fan 1, fin 2, windshield 3, automatic heat regulator 4 and exhaust vent 5 constitute, and formation cold wind airflow temperature automatic control forced heat radiation passage, described pressure fan, be fixed on a end above the fin 2 with screw 8, the air draught end upwards, outlet air end is downward, make cold wind directly dispel backing, described windshield 3 covers on the other end above the fin, because of being dust pan shape, cold wind can only be given 10 heat radiations of LED driving power after exhaust vent 5 is discharged by the tail end that inwall flows in the windshield.Windshield is fixing with screw and lamp lower casing 9, described automatic heat regulator 4 is contained in the heating surface in the fin, cement with heat conductive silica gel 7, described exhaust vent is arranged on the tail end of lamp lower casing 9, and be drilled with the aperture of a plurality of air-out, the filtration silk screen is housed in the hole, prevents that dust and little winged insect from piercing in the shell, says further, force fan, fin, automatic heat regulator, windshield, after installing in order, fin is coated heat conductive silica gel 7, is screwed together on the heat conduction fixed head 6 of lamp lower casing, buckles the lamp upper casing and is an integral body.

Above-mentioned structure, force fan power supply can use 220V, because the switching of fan is to be controlled automatically by automatic heat regulator, this automatic heat regulator is provided with 25 ℃-40 ℃ of temperature values, and superhigh temperature can operate as normal in the summer of sweltering heat so can guarantee LED high-power illumination lamp fully.

The utility model is not limited to above-mentioned embodiment, no matter do any variation on its shape or structure, everyly utilizes above-mentioned structural principle to form, and all is a kind of distortion of the present utility model, all should think and drop within the utility model protection domain.
