Abstract
The utility model discloses an LED cooling device installed at the bottom of an aluminum substrate of a light. An LED light source is fixed at the top of the aluminum substrate. The cooling device comprises a press plate and a plurality of heat conducting and cooling fins made of heat conducting and cooling materials, wherein a plurality of fixing holes are arranged on the press plate and bosses are arranged on the heat conducting and cooling fins. During installation, the heat conducting and cooling fins penetrate through the fixing holes of the press plate, then the press plate and the aluminum substrate are fixed through fixing parts, and therefore the heat conducting and cooling fins are closely attached to the bottom of the aluminum substrate. According to the cooling device, the structure of cooling media is simplified, even materials such as graphite and heat conducting ceramic can be processed into required shapes easily to match with the cooling device, the cost is easy to control, and the cooling effect is good.
Description
Technical field
The utility model relates to lighting field, espespecially a kind of LED heat abstractor.
Background technology
Recent years, along with the continuous maturation of LED technology, just appearing at daily life by feat of the LED product of premium properties among.But therefore led chip needs large-scale integrated on aluminium base because single light-emitting area is narrow usually, forms a larger light emitting source, but so just causes amount of heat to gather.Because the long-time accumulation of heat causes local temperature too high, can burn out LED lamp and chip, so the heat dissipation problem of LED light fixture has affected the large-scale application of LED.
On the other hand, graphite, thermal conductive ceramic are (such as AL
2O
3, SiC) etc. the heat conduction and heat radiation ability of material high, have the great potential of in the LED heat sink material, using.Although these materials have good heat conductivility, difficulty (most radiator structure is radiation fin type) relatively aspect machine-shaping particularly is difficult to combination with aluminium base, is difficult for fixing.These shortcomings have hindered their application in LED lamp radiator.
The utility model content
For the present stage technological deficiency, technical problem to be solved in the utility model is to provide a kind of LED heat abstractor, and it can effectively improve the radiating effect of LED, and has reduced cost, and simple in structure, easy to use.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of LED heat abstractor is installed in the aluminium base bottom of light fixture, and this aluminium base top is fixed with led light source; This device comprises pressing plate and some heat conduction and heat radiation fins of being made by the heat conduction and heat radiation material, described pressing plate is provided with some fixing holes, described heat conduction and heat radiation fin is provided with boss, during installation, the heat conduction and heat radiation fin is passed in the fixing hole of pressing plate, by fixture pressing plate and aluminium base are fixed again, thereby the bottom of heat conduction and heat radiation fin with aluminium base fitted tightly.
Also be provided with at least one deck step on the described heat conduction and heat radiation fin, every layer of step relocates a block pressur plate, with fixture each pressing plate and aluminium base fixed afterwards.
Be coated with heat-conducting silicone grease between the contact-making surface of described heat conduction and heat radiation fin and aluminium base.
After adopting such scheme, the utlity model has following advantage:
1. adopt some heat conduction and heat radiation fins, absorb the amount of heat that rests on the aluminium base plate, guaranteed the LED lamp, and made the temperature of aluminium base maintain metastable scope, guaranteed that LED can keep long lighting requirement.
2. the heat conduction and heat radiation fin structure that adopts is simple, only is provided with boss or step at a barred body, consists of the structure of T shape or similar T shape.When Practical manufacturing, boss can be the boss of ring-type, also can be the boss of lug-shaped, the structure of this heat radiating fin of having simplified, even the materials such as graphite, thermal conductive ceramic also can process at an easy rate, so cost is low, and radiating effect is good again.
3. the pressing plate that is used for fixing the heat conduction and heat radiation fin not only can play fixation, can also play the effect of increasing heat radiation area, thereby further increases radiating effect.
4. described pressing plate can also can be simplified the structure of LED lamp as gripper shoe, plays the effect that reduces the LED light fitting quality.
5. can conveniently expand the quantity of pressing plate, more the long-pending larger radiating effect of multi-contact surface is better through the test pressing plate.
