Abstract
The utility model discloses a radiator for a high-power LED lamp, which belongs to the field of LED lamps. The radiator comprises a heat radiation baseplate and a plurality of heat radiation fins arranged on the heat radiation baseplate; the heat radiation baseplate is cylindrical ring shaped; a plurality of groups of heat radiation fins are uniformly distributed at the exterior of the cylindrical ring shaped heat radiation base, a heat radiation base on which a high-power LED lamp is mounted is arranged in the centre of the interior of the cylindrical ring shaped heat radiation baseplate, and the heat radiation baseplate is connected with the heat radiation base through a plurality of heat radiation ribs. The increment of the heat radiating area ensures that the heat radiating rate is accelerated, the requirements of LED light source for heat radiation are met, and the service life is improved; and the volume of the radiator is small, thereby lowering the manufacturing costs of the LED lamps and improving the market competitiveness of the LED lamps.
Description
Technical field
The utility model belongs to the LED field of light fittings, relates in particular to a kind of heat radiation device for large power LED lamp.
Background technology
It is long that LED (light emijjing diode) has the life-span, the light efficiency height, and radiationless, advantages such as low-power consumption belong to the energy-conserving and environment-protective product; Great power LED adopts integrated encapsulation technology, and light efficiency is higher, and is more powerful, and volume is little, so high-power LED lamp also continues to bring out.
Existing LED light fixture, the plurality of LEDs light sources that adopt are installed on the heat-radiating substrate more, and heat-radiating substrate mostly is tabular, because the light source requirements of LED light fixture distributes the heat of chip fast, otherwise led light source will be put aside heat, make light source light decay occur, shorten the life-span of LED light fixture, use the radiator of this structure, heat is not easy to distribute, area of dissipation is little, can cause the bulky of light fixture again if increase area of dissipation, and the light fixture price rises.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of good heat dissipation effect, heat radiation device for large power LED lamp that volume is little are provided, the main improvement is heat-radiating substrate is made into the cylinder annular, at substrate outer setting radiating fin, and the inner cooling base of installing of substrate.Specifically implement like this: a kind of heat radiation device for large power LED lamp, comprise heat-radiating substrate and on some radiating fins, it is characterized in that heat-radiating substrate is that cylinder is ring-like, the outside many group radiating fins that evenly distribute of heat-radiating substrate that cylinder is ring-like, the ring-like heat-radiating substrate inside center of cylinder is provided with the cooling base that high-power LED light source is installed, and described cooling base is linked to each other by many radiating ribs with heat-radiating substrate.The area of dissipation of the radiator of this structure increases greatly, has accelerated radiating rate, and the radiator volume is little, has reduced the cost of light fixture.
Radiating fin of the present utility model is the straight-tooth shape, is uniformly distributed in the periphery of the ring-like heat-radiating substrate of cylinder, and the radiating fin both sides are equipped with jagged groove.
Led light source is installed for convenience, and the shape of cooling base and the aluminium base of great power LED match, and are typically designed to circular or square.
The profile of the utility model radiator is except that cylindrical, and the form of subcylindrical also belongs to the protection domain of the technical program.
The beneficial effects of the utility model are: the structure of having improved radiator, make area of dissipation increase, thereby accelerated radiating rate, be used for the LED light fixture, be particularly useful for high-power LED lamp, guaranteed the requirement of led light source heat radiation, prolonged service life, the volume of radiator is little, reduces the light fixture cost, promotes the market competitiveness of LED light fixture.Same external diameter big or small identical radiator compare with radiator of the present utility model, radiator of the present utility model increases by 40% than the area of dissipation of common radiator.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
A kind of heat radiation device for large power LED lamp, comprise heat-radiating substrate 3 and on some radiating fins 2, heat-radiating substrate 3 is that cylinder is ring-like, the ring-like heat-radiating substrate 3 outside many groups that evenly distribute of cylinder are the radiating fin 2 of straight-tooth shape, radiating fin 2 both sides are equipped with jagged groove, ring-like heat-radiating substrate 3 inside center of cylinder are provided with the cooling base 1 that high-power LED light source is installed, described cooling base 1 is linked to each other by many radiating ribs 4 with heat-radiating substrate 3, the shape of cooling base 1 and the aluminium base of great power LED match, and are typically designed to circular or square.
