The embedded aid-to-navigation light radiator of a kind of great power LED
Technical field
The utility model 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 due to present technical limitations, the photoelectric transformation efficiency of present stage LED is relatively poor, approximately only has 15% to 20% left and right 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, the 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 is mainly 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 is only 8 cun, the light fixture Integral sealing, narrow space, can not carry out effective free convection, the embedded navaid lamp radiator of original LED can't satisfy the great power LED cooling demand.
The utility model content
Goal of the invention of the present utility model is: provide a kind of great power LED embedded aid-to-navigation light radiator, can solve heat dissipation problem.
The technical solution adopted in the utility model is such: the embedded aid-to-navigation light radiator of a kind of great power LED, the radiator body that comprises indent, some through holes, some screwed holes two and some locating holes are set bottom the inner concave of described radiator body, through hole facilitates cable to pass the bottom, screwed hole two and locating hole are respectively used 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 rectangular configuration, be respectively used to fix an aluminium base, the rounded structure of described radiator external body.Certainly female parts can be also the shapes such as circle, isosceles or equilateral triangle, select as required, and be mainly 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 radiator body respectively has one.If selected circular concave shape, be isolated into two semicircles by division board; If selected isosceles or equilateral triangle, 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 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 the integral type structure.
As preferably, the material of described radiator body is copper.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, simplified the coupling part of aluminium base and radiator, the aluminium base pedestal has been simplified on 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, and thermal conductivity coefficient is high, conducts heat fast;
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 utility model to dispel the heat, and the LED temperature can be controlled at 60 ℃ of left and right, has extended the service life of LED navaid light fixture.
