Technical field

The utility model relates to a kind of LED lamp heat conducting structure and heat abstractor thereof, refers to especially a kind ofly the heat of LED light fixture to be conducted to fast its heat abstractor person.

Background technology

Known LED is that aluminium base is located in the LED weldering when being provided with, and then is attached on the heat pipe again, and this known way has following drawback after enforcement:

1, if known LED is the desire heat radiation, must after conducting to heat pipe with heat, disperse aluminium base mostly, hardly realize that the media that heat that LED produces transmits scriptures is many more, the heat that last heat pipe is dispersed is few more, be because of central media of transmitting scriptures can be with the heat absorption of major part, the effect of acomia heat dissipation capacity.

2, known LED welds the aluminium base of establishing, and its price goes up with the rising of international price recently day by day, not only can cause the cost of general heat abstractor to improve thus, also is a burden greatly to the consumer.

The utility model content

The purpose of this utility model is to provide a kind of LED lamp heat conducting structure, wish design thus, a kind of conductive structure that more is better than known LED light fixture is provided, makes it quicker and directly conduct heat on the heat abstractor and exhale, be the main purpose of utility model.

And another purpose of the present utility model is, a kind of heat abstractor that can interosculate with above-mentioned LED lamp heat conducting structure is provided, wish design thus, a kind of device that importing into heat is dispersed that can be quicker and certain is provided, be another utility model purpose of the present utility model.

Via as can be known above, for being implemented to aforementioned purpose, the technical scheme that the utility model adopted is for providing a kind of LED lamp heat conducting structure and heat abstractor thereof, it mainly includes a plurality of LED light fixtures, a plurality of heat-conducting blocks, a plurality of pcb boards and a plurality of heat pipe are formed, this LED light fixture is the LED lamp with height illumination functions, it is located at a side of heat-conducting block, and this heat-conducting block is the high-termal conductivity metal blocks with geometry, this pcb board is for having circuit and insulation, adiabatic geometric form plate body, and on this pcb board, be provided with a plurality of open-works, in order to embed heat-conducting block, and this heat pipe is the metal hollow tube of high-termal conductivity, it is a side that is fitted in heat-conducting block, wherein, the thickness of this heat-conducting block is slightly larger than the thickness of pcb board, so can make heat-conducting block be convexly equipped with a side at pcb board, and its external diameter is slightly less than the internal diameter of open-work on the pcb board, so can make heat-conducting block be easy to embed in the open-work of pcb board, and a side of this heat pipe is provided with planar portions, being used to fit is convexly equipped with heat-conducting block in pcb board one side, thereby will be shed by the heat that heat-conducting block imports into; And LED lamp heat conducting structure of the present utility model and heat abstractor thereof are when implementing, earlier heat-conducting block is embedded in the open-work of pcb board, again the LED light fixture is ironed and be welded on the position that is embedded with heat-conducting block in the pcb board, and make the bottom surface of LED lamp contact with heat-conducting block, a last side that again heat pipe is located at pcb board gets final product, therefore, can make the LED lamp fast heat be reached heat-conducting block, heat sink to heat pipe and it is dispersed by heat-conducting block again by the bottom surface.

By technique scheme, the utility model has following advantage at least:

1, more direct and transmit heat fast: because LED lamp heat conducting structure of the present utility model and heat abstractor thereof are by heat-conducting block being located at the centre of LED light fixture and heat pipe, and then with the conduction of heat that the LED lamp produced and disperse, like this then, be the most direct and quick and certain without other media.

2, the certain minimizing of cost: because LED lamp heat conducting structure of the present utility model and heat abstractor thereof use pcb board installing LED light fixture, give up industry aluminium base commonly used in the past, effect is the same, but price only needs less than 1/10th, certain reduces cost, also Tong Shi raising industry applications.
