Abstract
The utility model discloses a heat radiation channel of an LED lamp bank, comprising the LED lamp bank, a lamp shape and a mounting plate, wherein the lamp shade and the mounting plate are fastened together to form a cavity; and the LED lamp bank is arranged at the inner side of the mounting plate and inside the cavity. The heat radiation channel of the LED lamp bank is characterized in that the wall of the cavity is provided with an air inlet and an air outlet, wherein the air inlet is communicated with a cold air source. With the heat radiation channel, the LED bulbs in the cavity can achieve complete heat radiation and temperature reduction.
Description
Technical field
The utility model belongs to illuminating lamp, relates to a kind of LED lamp group heat dissipation channel specifically.
Background technology
As shown in Figure 1, the structure of LED lamp has generally comprised LED lamp group, lampshade and installing plate, and described lampshade and installing plate snap together, and forms cavity, and LED lamp group is installed in the inboard of installing plate, and is positioned at cavity.The high-power LED lamp group in the course of the work, temperature can raise, thereby makes electric current become big, causes the heating of LED lamp group because the heat conduction, the installing plate of LED lamp group also can generate heat, if untimely heat radiation can cause short circuit easily, and influence the service life of LED lamp group.The radiating mode that present LED lamp group adopts as shown in Figure 1, radiator overlays on the installing plate, and closely connect with it, on radiator, stack blower fan again, blower fan is directly aimed at radiator blowing heat radiation, cooling radiator, thus the heat of installing plate is taken away, the temperature of installing plate is reduced, reduce the temperature of LED lamp group indirectly.But we know that LED lamp group is at adstante febre, and the place that temperature is the highest is the lamp pearl of LED lamp group, are not the pin of installing plate and LED lamp.Because the pin of installing plate and LED lamp is not the heating main body, therefore this radiating mode can only be taken away LED lamp group heat seldom, and the big LED lamp pearl of caloric value that is positioned at enclosed cavity does not obtain effective radiating and cooling and handles.
The shortcoming of prior art is: because the big LED lamp pearl of caloric value is positioned at sealed hollow, existing radiating mode can not make LED lamp pearl obtain efficiently radiates heat, and radiating efficiency is poor.
The utility model content
The purpose of this utility model is to provide a kind of LED lamp group heat dissipation channel, can carry out abundant radiating and cooling to the LED lamp pearl in the lampshade.
The technical solution of the utility model is as follows: a kind of LED lamp group heat dissipation channel, include LED lamp group, lampshade and installing plate, described lampshade and installing plate snap together, and formation cavity, described LED lamp group is installed in the inboard of installing plate, and being positioned at described cavity, its key is: have air inlet and air outlet on the wall of the chamber of cavity, described air inlet communicates with the cooling wind regime.
Air inlet, cavity, air outlet form a cooling air channel, and the cooling air that the cooling wind regime produces can be taken away the heat of LED lamp pearl through this cooling air channel, thereby reach the purpose of abundant heat radiation.
Described air inlet is positioned at an end of installing plate, and described air outlet is positioned at the other end of installing plate.
The outside at described installing plate closely is connected with radiator, has n bar S shape heat dissipation wind channel in this radiator, and the import of S shape heat dissipation wind channel communicates with the cooling wind regime, and outlet communicates with the external world.
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, cause the installing plate mid portion to form the heat radiation blind area, it is insufficient to dispel the heat, after adopting S type air channel, can make the even inswept monoblock installing plate of cooling air, avoid forming the blind area, make the installing plate heat radiation fully, also promoted the heat radiation of LED lamp group indirectly.
Described cooling wind regime is a blower fan.
The outlet of described S shape heat dissipation wind channel communicates with described air outlet, and is connected with dry air channel, and the drive circuit board of LED lamp group is installed in this drying air channel.
Wind is mobile in the dry air channel, can keep the drying of drive circuit board.
Described air inlet is equipped with air filter screen.
Air filter screen can prevent that impurity from entering lampshade.
Remarkable result: LED lamp group heat dissipation channel can not only make the lamp pearl of LED lamp group fully be dispelled the heat, and can also make LED pin and installing plate obtain Homogeneouslly-radiating, fully reduces the temperature of LED lamp group, and utilizes flowing of wind, keeps the drying of drive circuit board.

Fig. 2 is a structural representation of the present utility model;
Fig. 3 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:
Shown in Fig. 2,3, a kind of LED lamp group heat dissipation channel, include LED lamp group 1, lampshade 2 and installing plate 3, described lampshade 2 snaps together with installing plate 3, and forming cavity a, described LED lamp group 1 is installed in the inboard of installing plate 3, and is positioned at described cavity a, have air inlet 4 and air outlet 5 on the wall of the chamber of cavity a, described air inlet 4 communicates with cooling wind regime 6.
Described air inlet 4 is positioned at an end of installing plate 3, and described air outlet 5 is positioned at the other end of installing plate 3.
The outside at described installing plate closely is connected with radiator 7, has n bar S shape heat dissipation wind channel 8 in this radiator 7, and the import of S shape heat dissipation wind channel 8 communicates with cooling wind regime 6, and outlet communicates with the external world.
Described cooling wind regime 6 is a blower fan.
The outlet of described S shape heat dissipation wind channel 8 communicates with described air outlet 5, and is connected with dry air channel 10, and the drive circuit board 9 of LED lamp group 1 is installed in this drying air channel 10.
