Abstract
The utility model relates to a light emitting diode (LED) lamp, which comprises an LED light source module and a heat radiation body, wherein the heat radiation body is an annular fin heat radiation body, the annular fin heat radiation body comprises an annular fin heat radiation body bracket and annular fins which are arranged inside the annular fin heat radiation body bracket, and the LED light source module is arranged inside the annular fins. The heat radiation body of the LED lamp adopts the annular fin heat radiation body, heat produced when the LED lamp works is radiated to the exterior along the air from bottom to top through a natural convection way; and a vertical-type fin heat radiation body is arranged on the annular fin heat radiation body, so the heat radiation effect of the lamp is better, and the air brings the heat inside the annular fin heat radiation body to the exterior through the vertical-type fin heat radiation body in a natural convection way from bottom to top. The structure of the LED lamp can greatly improve the natural convectional efficiency of the heat radiation effective area and the fins. The LED lamp has stable performance, durable and high-efficient heat radiation effect and a long service life.
Description
Technical field
The utility model belongs to technical field of lamps, specifically is meant a kind of LED light fixture.
Background technology
Along with improving constantly of people's living standard, in the life that is applied to people more and more widely of LED light fixture, in enterprises and institutions, hall, meeting room, workshop, shop, hospital, hotel, hotels and other places.
At present, the input power of LED light fixture only has 15～20% to convert light to, and all the other 80～85% forms that convert heat to discharge, if the not in good time discharge of these heat, will cause the light fixture operating temperature too high and influence problems such as luminous efficiency and service life.LED light fixture great majority on the existing light fixture market have only the vertical fin radiator of employing to dispel the heat, the heat radiation of vertical fin radiator effectively district is less, heat raising along with the LED light fixture, because the limited light fixture heat-sinking capability variation that makes in free convection zone, not only cause the light fixture power consumption many, also shortened the service life of light fixture, serious restriction the consumption market of light fixture.
The utility model content
Technical problem to be solved in the utility model provides the LED light fixture of a kind of good heat dissipation effect, stable performance and long service life.
For solving the problems of the technologies described above, the utility model is realized by the following technical solutions:
A kind of LED light fixture, comprise led light source module and radiator, described radiator is annular fin radiator, and this annular fin radiator comprises annular fin radiator support body and be located at the interior annular fin of annular fin radiator support body that the led light source module is arranged in the annular fin.
The prioritization scheme of such scheme is as follows:
Be provided with the vertical fin radiator that is connected with annular fin radiator above the above-mentioned annular fin radiator.
Be provided with the installing hole that the led light source module is installed between the above-mentioned annular fin.
Above-mentioned led light source module is at least one.
The utlity model has following remarkable result:
The radiator of the utility model LED light fixture adopts annular fin radiator, and the heat that produces during the work of LED light fixture dissipates to the external world in the free convection mode from bottom to top by air; Vertical fin radiator is set on annular fin radiator, makes the light fixture radiating effect better, air dissipates to the external world with the heat in the annular fin radiator through vertical fin radiator in the free convection mode from bottom to top.This LED fitting structure can significantly improve heat radiation effectively district and fin free convection usefulness, the stable performance of light fixture, radiating effect persistent high efficiency, long service life.
Description of drawings
Accompanying drawing 1 is faced structural representation for the utility model embodiment one;
Accompanying drawing 2 is embodiment one perspective view;
Accompanying drawing 3 is faced structural representation for the utility model embodiment two;
Accompanying drawing 4 is embodiment two perspective view.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
Embodiment one:
Shown in accompanying drawing 1～2, the LED lamp installation that present embodiment discloses is on ceiling or wallboard, and the LED light fixture can be light fixtures such as LED pendent lamp, LED shot-light, can be used for the indoor and outdoors illumination.This LED light fixture comprises led light source module 1 and radiator.Wherein, led light source module 1 is at least one, radiator is annular fin radiator 2, this annular fin radiator 2 comprises annular fin radiator support body 21 and the annular fin of being located in the annular fin radiator support body 21 22, between annular fin 22, be provided with installing hole, led light source module 1 is installed in the installing hole, is connected with led light source module 1 for led light source module 1 provides the electric wire of power supply to pass installing hole.
In this programme, led light source module 1 is three.
During the work of the utility model LED light fixture, led light source module 1 constantly gives out heat, the heat that light fixture produces is stranded in the annular fin radiator 2, air flows in the free convection mode in environment from bottom to top, cold air from bottom to top passes annular fin radiator 2 and takes away heat, heat dissipates to the light fixture radiator external world with cold air, thereby improve the heat area of dissipation greatly, accelerating heat distributes, greatly reduce the operating temperature of light fixture, guarantee the service behaviour of light fixture, prolong the service life of light fixture.
Embodiment two:
Shown in accompanying drawing 3～4, structure proximate among LED light fixture that present embodiment disclosed and the embodiment one, difference is to be provided with vertical fin radiator 3 above the annular fin radiator 2.
During the work of the utility model LED light fixture, led light source module 1 constantly gives out heat, the heat that light fixture produces is stranded in the annular fin radiator 2, air flows in the free convection mode in environment from bottom to top, cold air from bottom to top passes annular fin radiator 2 and vertical fin radiator 3 is taken away heat, heat dissipates to the light fixture radiator external world with cold air, thereby improve the heat area of dissipation greatly, accelerating heat distributes, greatly reduce the operating temperature of light fixture, guarantee the service behaviour of light fixture, prolong the service life of light fixture.
The foregoing description is the preferred version that the utility model is realized; and it is non-limiting exhaustive; the utility model can also have other variations under same idea; need to prove; under the prerequisite that does not break away from the present utility model design, any conspicuous replacement is all within the utility model protection domain.
