Description
Technical field
The present invention relates to a kind of radiator, particularly a kind of radiator for the embedded aid-to-navigation light of great power LED.
Background technology
One of advantage of LED is to have very high photoelectric transformation efficiency, but because present technical limitations, the photoelectric transformation efficiency of present stage LED is relatively poor, approximately has only 15% to 20% left and right sides electric energy to transfer light output to, all the other all are converted into heat energy, and these heat will cause the temperature of LED to rise.When temperature raises, problems such as operating voltage reduces, light intensity reduces, light wavelength is elongated can appear, and the LED light fixture also will sharply descend service life.So solving heat dissipation problem is a very important job for the two-way white light LEDs runway center line light in airport.
The embedded navaid light fixture of LED radiating equipment matter mainly is aluminium alloy 6063,6061, ADC12 at present, can satisfy the low-power LED radiating requirements.But some navaid light fixture needs great power LED could satisfy the visual demand in airport, because the recessed light fixture cover diameter of fixed heat sink only is 8 cun, light fixture integral body is airtight, the space is narrow and small, can not carry out effective free convection, the embedded navaid lamp radiator of original LED can't satisfy the great power LED cooling demand.
Summary of the invention
Goal of the invention of the present invention is: provide a kind of great power LED embedded aid-to-navigation light radiator, can solve heat dissipation problem.
The technical solution used in the present invention is such: the embedded aid-to-navigation light radiator of a kind of great power LED, the radiator body that comprises indent, the inner concave bottom of described radiator body arranges some through holes, some screwed holes two and some locating holes, through hole makes things convenient for cable to pass the bottom, screwed hole two and locating hole are respectively applied to the fixing and location of aluminium base, described radiator external surface is provided with some fins, and top surface edge arranges some screwed holes one.
As preferably, the rectangular structure of described radiator body female parts, and have division board to be isolated into two parts in the middle of the rectangular configuration, be respectively applied to fix an aluminium base, the rounded structure of described radiator external body.Certainly female parts also can be shapes such as circle, isosceles or equilateral triangle, select as required, and mainly be the shape that depends on aluminium base to be put into.
As preferably, the through hole of two parts bottom that is isolated into by division board in the radiator body respectively has one.If selected circular concave shape, then be isolated into two semicircles by division board; If selected isosceles or equilateral triangle, then still be isolated into two little triangles by division board.
As preferably, the screwed hole one of described radiator body top surface edge respectively distributes near the four edges of rectangular configuration one.
As preferably, the fin on the described radiator external surface has five, and all the end from radiator extends to the other end always along the bottom surface.The design of fin can effectively increase area of dissipation.
As preferably, described radiator body is integral structure.
As preferably, the material of described radiator body is copper.
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, simplified the coupling part of aluminium base and radiator, the aluminium base pedestal has been simplified on the radiator;
2, by division board, can separately fix two aluminium bases, radiator is single element like this, has reduced thermal resistance, is conducive to the quick conduction of heat;
3, radiator adopts copper material, the thermal conductivity coefficient height, and it is fast to conduct heat;
4, the radiator outer surface has fin, has increased area of dissipation, is conducive to scattering and disappearing of heat;
5, simple in structure, good heat dissipation effect in the little space in airtight LED recessed light fixture, adopts the present invention to dispel the heat, and can prolong the service life of LED navaid light fixture with the control of LED temperature about 60 ℃.
