Abstract
A high-power LED down lamp belongs to the field of LED lamps. The LED down lamp comprises a casing, a radiator arranged inside the casing and an LED light source. A reflector and a light transmission plate are mounted at the upper part of the casing; a driving power supply is arranged at the lower part of the casing; an opening is sealed by a cover plate; the heat radiation baseplate of the radiator is cylindrical ring shaped, a plurality of heat radiation fins are uniformly distributed on the exterior of the cylindrical ring shaped heat radiation baseplate; a heat radiation base on which a high-power LED light source is mounted is arranged in the center of the interior of the cylindrical ring shaped heat radiation baseplate; the heat radiation base is connected with the heat radiation baseplate through a plurality of heat radiation rids; the improvement on the structure of the radiator ensures that the radiating area is increased, thereby quickening the heat radiation speed, meeting the requirements of the LED light source for the heat radiation, and prolonging the service life; the volume of the radiator is small, and the manufacturing cost of the lamp is low.
Description
Technical field
The utility model belongs to the LED field of light fittings, relates in particular to a kind of high-power LED tube light.
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.
The light source that existing LED Down lamp light fixture uses is traditional common bulb or energy-saving bulb.This conventional light source has power consumption big, the temperature height, and poor safety performance, light efficiency is paid no attention to deficiencies such as thinking of the life-span weak point.And high-power LED light source is the environmental protection light source, is more and more accepted and payes attention to by people.
Summary of the invention
The utility model provides a kind of new high-power LED tube light just in order to overcome above-mentioned deficiency, its efficient height, and volume is little, and power consumption is few, and the life-span is long.Main innovation is to adopt novel heat radiator dedicated, promptly cylindrical radiator, and area of dissipation increases greatly, has accelerated radiating rate, and the radiator volume is little, has reduced the cost of light fixture.Specifically implement like this: a kind of high-power LED tube light, comprise radiator, led light source in housing, the housing, housing top is equipped with reflector and light-passing board, lower housing portion is equipped with driving power, seal by cover plate, the heat-radiating substrate that it is characterized in that radiator 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 big or small identical radiator of same external diameter is compared with radiator of the present utility model, and the radiator that the utility model adopts increases by 40% than common area of dissipation.
The radiating fin of the radiator that the utility model adopts 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 the cooling base of radiator 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 light-passing board that the utility model adopts is the PC light-passing board, and is rounded, the even four cone particles that distribute of circular surface, and the PC plate simultaneously is smooth plane.
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.Compare with traditional Down lamp, light source is LED, more power saving, and efficient is higher, and secondly, the led light source bright dipping is comparatively even, adopts the PC plate that has down four taper particles, more can effectively control dazzle, makes bright dipping softer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model radiator.
The specific embodiment
A kind of high-power LED tube light, comprise housing 5, radiator 6 in the housing, led light source 4, housing 5 tops are equipped with reflector 1,3 and circular PC light-passing board 2 (PC light-passing board 2 is loaded between reflector 1 and 3, bayonet socket connects), PC light-passing board 2 one sides are smooth plane, the even four cone particles that distribute of its circular surface, housing 5 bottoms are equipped with driving power 7, are sealed by cover plate 8, and the heat-radiating substrate 63 of radiator is that cylinder is ring-like, heat-radiating substrate 63 outside many group radiating fins 61 that evenly distribute that cylinder is ring-like, radiating fin 61 is the straight-tooth shape, is uniformly distributed in the periphery of the ring-like heat-radiating substrate 63 of cylinder, and radiating fin 61 both sides are equipped with jagged groove; Ring-like heat-radiating substrate 63 inside center of cylinder are provided with the cooling base 62 that high-power LED light source 4 is installed, the shape of cooling base 62 and the aluminium base of great power LED match, can be for circular or square, cooling base 62 is linked to each other by many radiating ribs 64 with heat-radiating substrate 63.
