Abstract
The utility model discloses a heat dissipation structure for a light-emitting diode (LED) lamp, which comprises an LED lamp body and a power supply. The lamp body is fixedly connected with the bottom end of a fan sleeve, the power supply and a fan are built in the fan sleeve, and the top end of the fan sleeve is provided with a face cover. The heat dissipation structure is reasonable in design and good in heat dissipation effect. The axial flow fan is built in between a lamp holder and a heating lamp lead circuit board assembly, and the fan is started to enable the air to be convected vertically, thereby accelerating release of internal heat quantity, achieving maximum heat transfer and resolving the technical problem of low heat dissipation efficiency in the prior art preferably.
Description
Technical field
The utility model relates to the LED light fixture, specifically is a kind of radiator structure that is used for high-power LED lamp.
Background technology
LED can only be converted into luminous energy with about 15%-25% electric energy, and remaining energy almost all changes into heat energy.If it is bad that heat dissipation problem solves, heat concentrates in the small-sized chip and can't discharge fast, makes that the chip internal temperature is increasingly high.The too high meeting of chip temperature brings many problems, as quickening device aging, accelerates the speed of LED light decay, reduction of service life, even also can cause chip to burn.Influence one of the light decay of LED lamp and the key factor in service life and come down to heat dissipation problem; How to solve effectively that natural heat dissipation speed is slow to become the technical problem that LED uses the field with weak effect.
The utility model content
To the problems referred to above, the utility model aims to provide the radiator structure of the good LED light fixture of a kind of heat dispersion.
For realizing this technical purpose, the scheme of the utility model is: a kind of radiator structure of LED light fixture, comprise LED lamp body and power supply, and said lamp body-fixed is connected fan cover bottom, and this fan cover is built-in with power supply and blower, and the top of fan cover is provided with cover.
As preferably, be fixed with a lampshade between said lamp body and the fan cover.
As preferably, the cover on the top of said fan cover is provided with the suspension hook of suspended lamp.
This programme reasonable in design, good heat dissipation effect; Because aerofoil fan is built between the lamp pearl circuit board module of lamp socket and heating; Starting fan makes up and down convection current of air; Quicken to discharge inner heat, realized the maximum delivered of heat, solved the low technical problem of prior art radiating efficiency better.
Description of drawings
Fig. 1 is the package assembly explosive view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.
As shown in Figure 1; The radiator structure of a kind of LED light fixture of the utility model most preferred embodiment, it comprises LED lamp body and power supply, said lamp body-fixed is connected a fan and overlaps 4 bottoms; This fan cover 4 is built-in with power supply and blower 3, and the top of fan cover 4 is provided with cover 2.Be fixed with a lampshade 5 between lamp body and the fan cover 4.The cover 2 on the top of fan cover 4 is provided with the suspension hook 1 of suspended lamp.
The above; Be merely the preferred embodiment of the utility model; Not in order to restriction the utility model, every technical spirit according to the utility model to any trickle modification that above embodiment did, be equal to replacement and improve, all should be included within the protection domain of the utility model technical scheme.
