Abstract
The utility model discloses a cooling wind tunnel for a large-power LED, comprising a blower, wherein the air inlet of the blower is communicated with the inlet of an LED radiator. The cooling wind tunnel is characterized in that the outlet of the LED radiator is connected with a dry wind tunnel that is internally provided with a driving circuit for the LED. In the utility model, the driving circuit can be kept dry, and the working efficiency of the blower on the heat dissipation of the LED can be improved.
Description
Technical field
The utility model belongs to illuminating lamp, relates to a kind of great power LED cooling air channel specifically.
Background technology
Great power LED can give out a large amount of heat in the course of the work, if untimely heat radiation, the phenomenon that can be short-circuited easily burns out the components and parts in the lamp group, therefore all can have blower fan that LED and drive circuit thereof are dispelled the heat in the process of using great power LED.
In the present radiating mode, the cold wind that blower fan blows out dispels the heat to drive circuit at first through overdrive circuit, and then LED is dispelled the heat, thereby finishes the heat radiation to the whole LED circuit.In fact, LED in the course of the work, the caloric value maximum be LED, the caloric value of drive circuit is much smaller relatively, so drive circuit the most important thing is to keep its drying.Because cold wind is relatively moist, at first through overdrive circuit the time, can bring drive circuit with the cold air of humidity, the security of drive circuit is reduced.Cold wind is behind overdrive circuit, and the temperature of wind has rising to a certain degree, becomes warm wind, is dispelled the heat to LED by Wen Fengzai, and radiating efficiency will be much lower for the radiating efficiency of cold wind.
The shortcoming of prior art is: the cold wind that blower fan blows out passes through LED more earlier through overdrive circuit, and the drive circuit drying effect is poor, influences the security of drive circuit, and simultaneously this heat radiation order has also reduced the radiating efficiency of LED.
The utility model content
The purpose of this utility model is to provide a kind of great power LED cooling air channel, can keep the drive circuit drying, and improves the operating efficiency of blower fan to the LED heat radiation.
The technical solution of the utility model is as follows: a kind of great power LED cooling air channel, include blower fan, the air outlet of this blower fan communicates with the import of LED radiator, and its key is: the outlet of LED radiator connects dry air channel, and the drive circuit of LED is installed in this drying air channel.
The cold wind that blower fan blows out is earlier through LED, again through overdrive circuit, can effectively improve the operating efficiency of blower fan to the LED heat radiation, reduce the temperature of LED faster, simultaneously, cold wind is becoming hot blast through behind the LED, when hot blast is blown over drive circuit, bring drive circuit with hot-air, can keep the drying of drive circuit.
Have n bar S shape heat dissipation wind channel in the described LED radiator, this S shape heat dissipation wind channel one end communicates with the air outlet of described blower fan, and the other end communicates with described dry air channel.
N is the natural number greater than 1.In the existing radiating mode, the wind direction both sides that blower fan is produced by boasting disperse, and cause the radiator mid portion to form the heat radiation blind area, it is insufficient to dispel the heat, and behind the employing S type air channel, can make the even inswept monoblock led circuit of cooling air, avoid forming the blind area, guaranteed the abundant heat radiation of LED.
The utility model also includes LED installing plate and lampshade, described lampshade and LED installing plate snap together, form cavity, LED is installed in the inboard of described LED installing plate, and be positioned at cavity, have air inlet and air outlet on the wall of the chamber of cavity, air inlet communicates with the air outlet of described blower fan, and air outlet connects dry air channel.
The heat dissipation capacity maximum is the lamp pearl that is positioned at lampshade among the LED, in the existing radiating mode, it mainly is the temperature that reduces LED by the temperature that reduces installing plate indirectly, fail to obtain heat radiation in the lampshade, cause the interior temperature of lampshade higher, after driving air port and air outlet on the wall of the chamber of cavity, the air in the lampshade is flowed, heat in the lampshade is taken out of, more effectively reduced the heat of LED.
In order better to promote the convection current of air in the lampshade, described air inlet is positioned at an end of installing plate, and described air outlet is positioned at the other end of installing plate.
Described air inlet is equipped with air filter screen.
Air filter screen can prevent that impurity from entering lampshade.
Remarkable result: the great power LED cooling air channel not only can effectively improve the operating efficiency of blower fan to the LED heat radiation, reduces the temperature of LED quickly, can also keep the drying of drive circuit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a S type heat dissipation channel structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, a kind of great power LED cooling air channel includes blower fan 1, and the air outlet of this blower fan 1 communicates with the import of LED radiator 2, and the outlet of LED radiator 2 connects dry air channel 3, and the drive circuit 4 of LED is installed in this drying air channel 3.Have n bar S shape heat dissipation wind channel 5 in the described LED radiator 2, these S shape heat dissipation wind channel 5 one ends communicate with the air outlet of described blower fan 1, and the other end communicates with described dry air channel 3.
Present embodiment also includes LED installing plate 6 and lampshade 7, described lampshade 7 and LED installing plate 6 snap together, form cavity a, LED is installed in the inboard of described LED installing plate 6, and be positioned at cavity a, have air inlet 8 and air outlet 9 on the wall of the chamber of cavity a, air inlet 8 communicates with the air outlet of described blower fan 1, and air outlet 9 connects dry air channel 3.
Described air inlet 8 is positioned at an end of installing plate 6, and described air outlet 9 is positioned at the other end of installing plate 6.
