Abstract
The utility model discloses a light-emitting diode (LED) lamp which comprises a circuit board and a light emitting body fixed on the upper surface of the circuit board. The LED lamp further comprises a heat conduction pipe fixed on the bottom face of the circuit board. Spiral first radiating fins are connected with two ends of the heat conduction pipe, a radiating board is further arranged below the middle of the heat conduction pipe, and a plurality of second radiating fins are arranged on the lower surface of the radiating board at intervals. Heat generated by the light emitting bodies is transferred to the first radiating fins and the second radiating fins through the heat conduction pipe, the spiral structure and the rectangular structure of the first radiating fins and the second radiating fins increase the heat exchange area of the fins and the air, the heat exchange efficiency is improved, and radiating can be better conducted on the LED lamp.
Description
Technical field
The utility model relates to LED lamp technical field, relates in particular to the LED lamp that a kind of thermal diffusivity is good.
Background technology
Along with the development of LED, LED is because the feature such as energy-saving and environmental protection, long working life enjoys the concern of all circles, the extensive use of LED oneself through becoming kind of a development trend.
Due to high-powered LED lamp in the course of the work, except luminous, produce amount of heat, and the height of LED junction temperature (chip temperature) directly affects the life-span of light fixture simultaneously.Therefore, high-powered LED lamp need to produce a large amount of heats when luminous derives.
Utility model content
The utility model is mainly to solve existing technical problem in prior art, thereby the LED lamp that a kind of thermal diffusivity is good is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
LED lamp of the present utility model, comprise circuit board and the illuminator that is fixed on described circuit board upper surface, also comprise heat pipe, described heat pipe is fixed on the bottom surface of described circuit board, the two ends of described heat pipe are all connected with spiral the first fin, and the below of described heat pipe mid portion is also provided with heat sink, the lower surface of described heat sink is equally spaced is provided with multiple the second fin.
Further, on described the first fin, also have louvre, described louvre be shaped as circle or ellipse.
Further, the two ends of described the first fin are also provided with a fan.
Further, described the second fin be shaped as rectangle.
Compared with prior art, the utility model has the advantage of: heat illuminator being produced by heat pipe conducts to the first fin and the second fin radiating fin, the helical structure of first, second fin radiating fin and rectangular configuration have increased the heat exchange area with air, improve heat exchanger effectiveness, and then better LED lamp has been dispelled the heat.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of LED lamp of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1, LED lamp of the present utility model, comprise circuit board 1 and the illuminator 2 that is fixed on circuit board 1 upper surface, this LED lamp also comprises heat pipe 3, and heat pipe 3 is fixed on the bottom surface of circuit board 1, and the two ends of heat pipe 3 are all connected with spiral the first fin 4, and the below of heat pipe 3 mid portions is also provided with heat sink 7, the equally spaced shape that is provided with multiple the second fin 8, the second fin 8 of lower surface of heat sink 7 is preferably rectangle, can be also other shapes.The heat that the utility model produces illuminator 2 by heat pipe 3 conducts to 4 of the first heat radiations and the second fin 8 radiating fins, the helical structure of first, second fin radiating fin (4,8) and rectangular configuration have increased the heat exchange area with air, improve heat exchanger effectiveness, and then better LED lamp has been dispelled the heat.
Preferably, the two ends of the first fin 4 are also provided with a fan 6.By fan 6 and spiral the first fin 4, air can be formed to spiral air flow, form the heat exchange of strong convection, and because also have louvre 5 on the first fin 4, natural air passes through louvre 5 to first fin 4 back to fan 6 those faces, accelerate the heat exchange of whole the first fin 4, good heat dissipation effect.In the utility model, louvre 5 be shaped as circle or ellipse, can be also other shapes.
Above, be 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 variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
