A kind of light emitting diode with cooling system
Technical field
The utility model relates to a kind of light emitting diode, especially a kind of light emitting diode with cooling system.
Technical background
Light emitting diode, LED, is a kind of solid-state cold light source, the advantage such as have environmental nonpollution, little power consumption, light efficiency is high, the life-span is long becomes the low-carbon energy-saving light source of new generation of the advantage most with alternative conventional light source.But because light-emitting diodes pipe volume is little, make the caloric value in its unit volume very high, temperature in unit volume is raise, and this will directly affect instantaneous brightness and the decay of luminescence degree of light emitting diode, has a strong impact on the performance raising of light emitting diode and the reliability of work.Therefore, for the heat radiation of light emitting diode, people have done a lot of Improvements, wherein, Granted publication number is that the utility model patent of CN202747075 discloses a kind of light emitting diode, comprise light-emitting diodes tube body, aluminium base, electronic refrigerating sheet, heat exchanger fin and fin, above-mentioned parts connect in turn, wherein, fin is vertically connected on heat exchanger fin, fin has a slice at least, and in the time having two fin at least, all fin are parallel to each other.But be not difficult to find, fin and heat exchanger fin to be connected contact area little, the heat transfer between heat exchanger fin and fin is limited, radiating effect also can be had a greatly reduced quality.
Utility model content
The purpose of this utility model is to provide a kind of light emitting diode with cooling system, solves the poor problem of heat radiation system radiating effect of existing light emitting diode.
In order to achieve the above object, the utility model provides following technical scheme: a kind of light emitting diode with cooling system, comprise light-emitting diodes tube body, aluminium base, radiator and fin, light-emitting diodes tube body is connected with the one side of aluminium base, the another side of aluminium base is connected with the first surface of radiator, second of radiator is connected with fin, and wherein, the cross sectional dimensions of one end that fin is connected with radiator is greater than the cross sectional dimensions of the other end.
Particularly, between fin and radiator, there is heat-conducting glue.
Further, described heat-conducting glue is heat conductive silica gel.
Particularly, the longitudinal section of fin is trapezoidal, triangle or " people " font.
The shape of second of the end surface shape of one end that particularly, fin is connected with radiator and radiator matches.
Further, at least two of fin.
The utility model is for the poor problem of heat radiation system radiating effect of existing light emitting diode, fin is set to the cross sectional dimensions than the other end with the cross sectional dimensions of radiator link, ensureing under the prerequisite large as far as possible with radiator connection area, the area of dissipation that has increased fin, has improved radiating effect.

Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
According to shown in Fig. 1 to Fig. 3, a kind of light emitting diode with cooling system of the utility model is described.
A kind of light emitting diode with cooling system, comprise light-emitting diodes tube body, aluminium base, radiator and fin, light-emitting diodes tube body is connected with the one side of aluminium base, the another side of aluminium base is connected with the one side of radiator, the another side of radiator is connected by heat conductive silica gel with at least two fin, wherein, the cross sectional dimensions of the first end that fin is connected with radiator is greater than the cross sectional dimensions of the second end, and the vertical sectional shape of fin is trapezoidal, the first end of each fin is arranged in parallel within on the face of radiator, and the face of radiator is all covered, as shown in Figure 1.
Further technical scheme is, the vertical sectional shape of fin is triangle, and the first end of each fin is arranged in parallel within on the face of radiator, and the face of radiator is all covered, as shown in Figure 2.
Further technical scheme is, the vertical sectional shape of fin is " people " font, and the first end of each fin is arranged in parallel within on the face of radiator, and the face of radiator is all covered, as shown in Figure 3.
Wherein, the end face of the link of fin and radiator is set to match with the shape of joint face according to the shape of joint face, ensures that fin is connected with the effective of radiator, ensures heat transfer efficiency between the two, and then the radiating efficiency of raising fin.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
