Abstract

The utility model discloses a radiating device of a high power light emitting diode spotlight. The radiating case of the utility model is fixed within the lamp housing and the front side wall of the radiating case is stuck on the back of the circuit wafer of the matrix arrayed light emitting diode and the left of the front side wall is provided with an air draught hole, while the right side wall of the radiating case is provided with a fan. Both left and right sides of the lamp housing is respectively provided with an air outlet and an air inlet, wherein the air draught hole is communicated with the air outlet via the air outlet pipe. The utility model adopts closed radiating device, therefore one flank of the radiating case is arranged with a fan and the other flank is arranged with an air draught hole to improve the heat dissipation, thereby the service time of the spotlight is greatly prolonged.

Description

The heat abstractor of high power LED illumination device
Technical field
The utility model relates to a kind of heat abstractor, relates to a kind of heat abstractor of high power LED illumination device particularly.
Background technology
LED illumination lamp claims semi-conductor lighting lamp again, it is the at present domestic and international consistent novel illumination lamp of regarding as energy-saving and environmental protection, but under the situation of urban look and the contour illumination of road lighting, use large-power light-emitting diodes array to contact, power is all at 20W-150W, big like this lighting power will produce high heat, if bulk temperature is not controlled at below 55 ℃, the service life and the illumination efficiency of large-power light-emitting diodes will be influenced directly.
Generally adopt at present open heat dissipating method: the back side of the radiator of arranging light emitting diode is exposed in the lamp housing.The shortcoming of this method is that radiating effect is not good, thereby reduced the service life of high power LED illumination device.
Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model has provided a kind of good heat dissipation effect, has made the heat abstractor of illuminating lamp growth in service life.
The technical solution of the utility model is: the heat radiation case of the heat abstractor of this high power LED illumination device is fixed in the lamp housing, the front side wall of heat radiation case is attached to the back side of circuit board of the light emitting diode that matrix arranges and the left side of front side wall has exhaust vent, the right side wall of heat radiation case is provided with fan, the and arranged on left and right sides of lamp housing has air outlet and air inlet, and exhaust vent is communicated with air outlet by discharge pipe.
Because adopted enclosed heat abstractor, and only open exhaust vent, make radiating effect better, thereby allow to increase the service life of illuminating lamp at the side dress fan and the opposite side of heat radiation case.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a right view of the present utility model;
Fig. 4 is the structure chart of heat radiation case of the present utility model.
The specific embodiment
With reference to the accompanying drawings, will be described in detail the specific embodiment of the present utility model.
Fig. 1 is a front view of the present utility model.The heat radiation case 1 (dotting among Fig. 1) of the heat abstractor of this high power LED illumination device is fixed in the lamp housing 8, the front side wall of heat radiation case 1 is attached to the back side of circuit board of the light emitting diode 7 that matrix arranges and the left side of front side wall has exhaust vent 5, the right side wall of heat radiation case 1 is provided with fan 2, the and arranged on left and right sides of lamp housing 8 has air outlet 11 and air inlet 9, and exhaust vent 5 is communicated with air outlet 11 by discharge pipe 10.Wherein dispel the heat case 1 and lamp housing 8 is connected by screw, and screw hole 15 as can see from Figure 4.Fig. 3 is a right view of the present utility model, can clearly see fan 2 from this figure.The driver 12 that drives light emitting diode matrix is in the left side of discharge pipe, and the circuit board at light emitting diode matrix place also is connected with reflection shield 6 and cloche 13.
Fig. 2 is a vertical view of the present utility model, and the rear wall of described heat radiation case 1 is an Aluminum cover 4, adopts the cover plate perfect heat-dissipating of this material.
Operation principle of the present utility model: produce high heat during large-power light-emitting diodes 7 work, one end of heat radiation case 1 is by dress fan 2 shown in Figure 3, fan 2 is by air inlet 9 air intakes of 14 air-supplies of the air channel in the middle of the heat radiation case 1 and lamp housing 8, keep the normal air circulation, fan passes through hot gas exhaust vent 5, discharges from air outlet 11 through discharge pipe 10.By this circulating air advance, hot gas goes out, and improved radiating effect greatly, the radiator after the sealing is compared with the radiator that does not seal, and adds fan equally, temperature differs 20 ℃, makes the operating temperature of high power LED illumination device remain on summer high temperature environment 55.Below, guaranteed service life and the luminous efficiency of high power LED illumination device below 35 ℃ winter.High power LED illumination device heat spreader structures of the present utility model is simple, effective, the lamp housing of configurable traditional street lamp, Projecting Lamp, searchlight can reach desirable effect, operating temperature is remained in 35 ℃-55 ℃, is the ideal product of novel illumination industry.
As shown in Figure 4, on Aluminum cover, be provided with transversely arranged fin 3.
Certainly the utility model is not limited to the foregoing description, as long as take the mode of sealing, all belongs to protection domain of the present utility model.
