By means of the LED lamp heat dissipation structure, the fins and the heat dissipation pipe are integrally arranged, the radiator is integrally attractive and simple, the radiator has enough metal materials to conduct heat through the metal fins, the radiator has the enough area to release heat through the plastic insulating layers on the outer portions of the metal fins, the optimal heat dissipation effect is achieved, manufacturing cost is reduced, a drive power source is usually arranged in the radiator, and potential safety hazards caused by the excessively high temperature of the overall radiator can be reduced through the insulating layers.

Description

LED lamp cooling structure
Technical field
The present invention relates to heat sink technology field, specifically refer to a kind of LED lamp cooling structure.
Background technology
Now; because LED light fixture had not only saved but also the feature of environmental protection; the application of LED lighting is more and more extensive; when LED light fixture conventionally can produce a large amount of heats in the time working; therefore high-power LED light fixture or for a long time must be equipped with heat dissipation equipment in the LED light fixture that uses state, thus the normal service life of LED light fixture guaranteed.On current market, common LEDLED lamp cooling structure is all-metal radiator, in the time that LED light fixture works long hours, the surface of all-metal radiator can reach quite high temperature, and the driving power of most LED light fixtures is arranged at the inside of radiator, and adopt high voltage, cause the potential safety hazard of exposed metal meeting uncertainty, separately there is a kind of radiator, adopted thermoplastic materials heat radiation, this plastics price is higher, makes the use cost of radiator very high, and this kind of radiator is without fin, and radiating effect is poor.
Summary of the invention
The object of the invention is to have overcome above-mentioned shortcoming of the prior art, provide a kind of good heat dissipation effect, low cost of manufacture, radiator to use safe LED lamp cooling structure.
For realizing above-mentioned object, LED lamp cooling structure of the present invention has following formation:
This LED lamp cooling structure, its main feature is, comprise and have a liking for sheet and radiating tube, this radiating tube is tubular, described radiating tube one end is for remaining silent, and the other end is light fixture connector, the described outer surface of having a liking for sheet and be inserted in described radiating tube, and extend axially along described radiating tube, the described surface of having a liking for sheet has insulating barrier.
In this LED lamp cooling structure, have a liking for sheet along the outer surface that is circumferentially evenly distributed in described radiating tube, and adjacent to have a liking for the spacing of sheet between described radiating tube outer surface be to have a liking for three times of sheet thickness.
The sheet of having a liking in this LED lamp cooling structure is that metal is had a liking for sheet.
Insulating barrier in this LED lamp cooling structure is plastic insulating layer.
The average thickness of the insulating barrier in this LED lamp cooling structure is less than or equal to 1mm.
The longitudinal section of having a liking for sheet in this LED lamp cooling structure can be rectangle or trapezoidal.
Radiating tube in this LED lamp cooling structure, described has a liking for sheet and described insulating barrier is integrated setting.
Adopted the LED lamp cooling structure of this structure, sheet is had a liking in heat radiation and radiating tube is integrated setting, and radiator integral is attractive in appearance, clean and tidy.Having a liking for sheet is metal material, the surface that metal is had a liking for sheet is covered with one deck plastic insulating layer, metal is had a liking for sheet and is guaranteed that this radiator has enough metal materials to conduct heat, plastic insulating layer guarantees that radiator has enough areas to carry out release heat, thereby play best radiating effect, and reduced the manufacturing cost of radiator, driving power is arranged at radiator inside conventionally, the setting of insulating barrier also can reduce the potential safety hazard causing because of radiator integral excess Temperature.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is structural representation of the present invention.
The specific embodiment
In order more clearly to understand technology contents of the present invention, describe in detail especially exemplified by following examples.
Refer to Fig. 1 and Fig. 2, this LED lamp cooling structure, comprise and have a liking for sheet 2 and radiating tube 1, this radiating tube 1 is tubular, radiating tube 1 one end is for remaining silent, the other end is light fixture connector, this light fixture connector is for being directly connected with the light fixture that needs heat radiation, have a liking for sheet slotting 2 and be located at the outer surface of radiating tube 1, and extend axially along radiating tube 1, the surface of having a liking for sheet 2 has insulating barrier, this insulating barrier is plastic insulating layer, have a liking for sheet 2 and be radial, and along the outer surface that is circumferentially evenly distributed in radiating tube 1, at the outer surface of radiating tube 1, the adjacent spacing of having a liking between sheet 2 is to have a liking for three times of sheet 2 thickness, have a liking for spacing between sheet 2 if adjacent too small, can affect radiating effect.Have a liking for sheet 2 and have a liking for sheet for metal, metal is faster than plastics heat conduction, because the sheet 2 of having a liking for of the present embodiment is had a liking for sheet for metal, the surface of having a liking for sheet 2 is coated with ambroin, make the metal material of the existing abundance of this radiator conduct heat, plastic insulating layer has guaranteed again to have enough areas to carry out release heat, makes this LED lamp cooling structure energy quick heat radiating in the time that light fixture is worked.And so inside and outside two-layer heat spreader structures is when making radiator improve radiating effect, reduces manufacturing cost.In order to play good radiating effect, the average thickness of insulating barrier is less than or equal to 1mm, and this insulating barrier both can play the effect of heat radiation, can play again insulating effect, thereby has guaranteed the security of LED lamp cooling structure.
The longitudinal section of having a liking for sheet 2 can be rectangle or trapezoidal, and the longitudinal section of having a liking for sheet of the present embodiment is trapezoidal, and the length of having a liking for sheet 2 low beam tool connector places is less than the length of nearly closed end, specifically refers to Fig. 1.
As the preferred embodiment of the present embodiment, radiating tube 1, has a liking for sheet 2 and insulating barrier and is integrated setting, thereby make heat spreader structures attractive in appearance, succinct, has a liking for not frangibility of sheet 2.
Adopted the LED lamp cooling structure of this structure, sheet is had a liking in heat radiation and radiating tube is integrated setting, and radiator integral is attractive in appearance, clean and tidy.Having a liking for sheet is metal material, the surface that metal is had a liking for sheet is covered with one deck plastic insulating layer, metal is had a liking for sheet and is guaranteed that this radiator has enough metal materials to conduct heat, plastic insulating layer guarantees that radiator has enough areas to carry out release heat, thereby play best radiating effect, and reduced the manufacturing cost of radiator, driving power is arranged at radiator inside conventionally, the setting of insulating barrier also can reduce the potential safety hazard causing because of radiator integral excess Temperature.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, description and accompanying drawing are regarded in an illustrative, rather than a restrictive.
