Description
Technical field
The present invention relates to field of LED illumination, a kind of heat abstractor of LED lamp is particularly related to.
Background technology
As the idea of energy-saving and emission-reduction and low-carbon environment-friendly is rooted in the hearts of the people, LED classes illuminating lamp is more and more widely used, especially
Its large-scale public place street lamp use, although LED illumination device have energy-conserving and environment-protective the characteristics of, in the mistake that it is illuminated
Cheng Zhonghui produces larger heat energy, causes internal junction temperature too high, if things go on like this easily causes inside chip and is burnt because temperature is too high
It is bad, therefore LED lamp needs radiator to be radiated.Existing passive heat radiation device, the purpose is in condition as light as possible
Under, the maximization of physics cooling surface area is pursued, so as to realize highest heat exchanger effectiveness, but common problem is to have ignored sky
Flow of air is only unable to reach best radiating effect for the importance of heat dispersion by heat loss through radiation.
The content of the invention
It is an object of the invention to provide a kind of energy increase air flow velocity, accelerate the Novel LED street lamp heat abstractor of radiating.
In order to reach above-mentioned purpose, solution of the invention is：
A kind of heat abstractor of LED lamp, including radiating shell and impeller sets；The radiating shell is provided with some vertical heat radiating fins
Piece, the impeller sets are coordinated between adjacent heat radiation fin by impeller axle.
The impeller sets are distributed in the both sides of radiating shell.
The impeller sets are symmetrically distributed in the both sides of radiating shell.
The impeller sets are distributed in the side of radiating shell.
Position on the radiating shell corresponding to impeller sets is provided with hollow hole.
The impeller sets are receded disk impeller group.
After said structure, impeller sets, convected air are combined with by impeller axle between each radiating fin of the invention
Just can impeller group rotate, it is not necessary to extra drive device, cost-effective and energy consumption, the impeller sets of rotation are by convected air
The main heating region in the middle of radiating shell is oriented to, the air velocity in this region is increased so that the heat of radiating shell quickly dissipates
Go out, solve the problems, such as that radiating shell radiates, extend the service life of LED lamp.

Specific embodiment
In order to technical scheme is explained further, the present invention is explained in detail below by specific embodiment
State.
As shown in Figures 1 to 4, present invention is disclosed a kind of heat abstractor of LED lamp, it includes radiating shell 1, described
Radiating shell 1 is provided with some vertical radiating fins 11.
It is of the invention it is critical that：As shown in figure 1, this is practical also including several impeller sets 4, impeller sets 4 are led to
Impeller axle 5 is crossed to be respectively fitting between adjacent heat radiation fin 11；The impeller axle 5 can be coordinate adjacent heat radiation fin 11 it
Between short axle body, it is also possible to be through the axis body long of multiple radiating fins 11, the smooth frictional force of the impeller axle 5 is small so that leaf
Wheel group 4 does not need extra drive device to be driven, and convected air just can rotate impeller sets 4.
The impeller sets 4 are distributed in the both sides of radiating shell 1, further, it is possible to be symmetrically distributed in the two of radiating shell 1
Side.To strengthen the circulation of air, the position on the radiating shell 1 corresponding to each impeller sets 4 is provided with hollow hole 12.
The impeller sets 4 can be receded disk impeller group so that air is radially flowed out from impeller sets 1.
Coordinate explanation operation principle of the present invention as a example by LED lamp of the invention below, as shown in Figures 2 and 3, wherein described
The LED light source plate 2 of LED lamp is closely locked on radiating shell 1 by screw 3 and screw 13.
When light fixture works, the heat of LED light source plate 2 can be transmitted on the zone line of radiating shell 1, and radiating shell 2 is attached
Near air is constantly heated and rises, while the cold air near radiating shell 2 can be continuously replenished and produce convected air, it is right
Stream air meeting impeller group 4 is rotated, and accelerates the flow rate of air, the heat-sinking capability of light fixture is greatly improved, so as to reduce light fixture
Bulk temperature；And the impeller sets 4 for rotating change the flow direction of convected air so that convected air is to the centre of radiating shell 1
Main heating region flowing, concentrates the air of both sides the main heating region of the centre for being oriented to radiating shell 1 and increases the area
The air velocity in domain, can accelerate the radiating of the main heating region in the middle of radiating shell 1, it is to avoid produce " heat in radiating shell 1
Island effect ", so as to protect LED lamp, increases the service life.
The impeller sets 4 are not limited to be distributed in the both sides of radiating shell 1, it is also possible to separately distributed in radiating shell 1
Side, it is also possible to direct the air to the main heating region and increase air flow velocity in the middle of radiating shell 1.
To sum up, impeller sets 4 are combined with by impeller axle 5 between each radiating fin 11 of the invention, convected air just can band
Dynamic impeller sets 4 are rotated, it is not necessary to which be oriented to for convected air by extra drive device, cost-effective and energy consumption, the impeller sets 4 of rotation
Main heating region in the middle of radiating shell 1, increases the air velocity in this region so that the heat of radiating shell 1 quickly sheds,
Solve the problems, such as that radiating shell radiates, extend the service life of LED lamp.
Certainly, the impeller sets 4 can also be driven by drive device, to obtain more preferable radiating effect.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common
Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from patent category of the invention.
