Abstract
The utility model discloses an LED (light emitting diode) lighting fixture of a counter flow type heat radiation structure. The LED lighting fixture comprises an LED lamp, a lens, a lens fixing ring, a counter flow type heat radiation lamp body, an aluminum substrate board, a rubber fixing base and a metal lamp holder, wherein the LED lamp is welded on the aluminum substrate board; the aluminum substrate board is fixed inside the counter flow type heat radiation lamp body; the rubber fixing base is fixed on the counter flow type heat radiation lamp body; the lens is pressed on the LED lamp through a lens fixing ring; the lens fixing ring is fixed on the counter flow type heat radiation lamp body; and the LED lighting fixture is characterized in that a plurality of through holes are arranged on the counter flow type heat radiation lamp body. The LED lighting fixture provided by the utility model has the advantages that the heat radiation efficiency of a heat radiator is improved, the phenomenon that the temperature is accumulated at the center of the lighting fixture is solved, and the service life of the lighting fixture is prolonged.
Description
Technical field
The utility model relates to a kind of LED light fixture, and specifically a kind of radiating efficiency that improves radiator has solved the phenomenon that the light fixture central temperature is gathered, and the LED light fixture of convection type radiator structure in the service life of light fixture has been grown in the court of a feudal ruler.
Background technology
In recent years, because the succeeding in developing of the LED of white light, LED began to enter into illuminating industry.LED belongs to cold light source; Compare with fluorescent lamp with white trifoliate orange lamp, it has long, the shock-resistant advantage such as fragmentation that promptly is difficult in power and energy saving, life-span, compares with fluorescent lamp; Do not glimmer in addition, toggle speed is fast, the advantage of environmentally safe, is regarded as perfect light source of new generation by the photoelectricity industry.Though LED is regarded as cold light source, still can produce certain heat during work, the operating temperature of LED generally should be less than 50 degree.Have data to show, when the operating temperature of LED reaches 55 when spending, its life-span will reduce half the.At present; The light-emitting area of the conventional LED lamp radiator in market does not generally all have passage, i.e. the heat at radiator center can not be directly taken away in directly convection current of air; Be formed centrally tropical island effect in the light fixture; The light fixture central temperature is gathered, and causes the LED light fixture light decay of this kind structure serious, directly the life-span of the whole lamp of influence.
Summary of the invention
The purpose of the utility model provides a kind of radiating efficiency that improves radiator, has solved the phenomenon that the light fixture central temperature is gathered, and the LED light fixture of convection type radiator structure in the service life of light fixture has been grown in the court of a feudal ruler.
The purpose of the utility model realizes through following technical scheme.
A kind of LED light fixture of convection type radiator structure; Comprise LED lamp, lens, lens retainer ring, convection type heat radiation lamp body, aluminium base, plastic cement holder and metallic lamp holder, the LED lamp is welded on the aluminium base, and aluminium base is fixed in the convection type heat radiation lamp body; The plastic cement holder is fixed on the convection type heat radiation lamp body; Lens scioptics retainer ring is pressed on the LED lamp, and the lens retainer ring is fixed on the convection type heat radiation lamp body, it is characterized in that: said convection type heat radiation lamp body is provided with a plurality of square through holes.
Said LED lamp is welded on the aluminium base through leadless soldering tin paste.
The aluminium base of said welding LED lamp is fixed on the convection type heat radiation lamp body through screw.
Said plastic cement holder is fixed on the convection type heat radiation lamp body through screw.
Said lens retainer ring is fixed on the convection type heat radiation lamp body through screw.
The utility model compared with prior art has the following advantages.
The utility model is compared the LED light fixture that existing light-emitting area does not have clear opening; The utility model is made convection type heat radiation lamp body with radiator, and this lamp body is made up of a plurality of square through holes, and the air of each square through hole can both convection current; Form the chimney convection effect, the cold air of constantly pouring into is taken away heat.Improve the radiating efficiency of radiator, solved the phenomenon that the light fixture central temperature is gathered, the service life of the long light fixture in the court of a feudal ruler.
Description of drawings
Fig. 1 is the structural representation of the LED light fixture of the utility model convection type radiator structure.
The specific embodiment
Describe in further detail below in conjunction with the LED light fixture of accompanying drawing the utility model convection type radiator structure.
As shown in Figure 1; The LED light fixture of the described a kind of convection type radiator structure of the utility model comprises LED lamp 1, lens 2, lens retainer ring 3, convection type heat radiation lamp body 4, aluminium base 5, plastic cement holder 6 and metallic lamp holder 7; The LED lamp is welded on the aluminium base; Aluminium base is fixed in the convection type heat radiation lamp body, and the plastic cement holder is fixed on the convection type heat radiation lamp body, and lens scioptics retainer ring is pressed on the LED lamp; The lens retainer ring is fixed on the convection type heat radiation lamp body, and convection type heat radiation lamp body is provided with several square through holes 8.The LED lamp is welded on the aluminium base through leadless soldering tin paste.The aluminium base of welding LED lamp is fixed on the convection type heat radiation lamp body through screw.The plastic cement holder is fixed on the convection type heat radiation lamp body through screw.The lens retainer ring is fixed on the convection type heat radiation lamp body through screw.The utility model is compared the LED light fixture that existing light-emitting area does not have clear opening; The utility model is made convection type heat radiation lamp body with radiator, and this lamp body is made up of a plurality of square through holes, and the air of each square through hole can both convection current; Form the chimney convection effect, the cold air of constantly pouring into is taken away heat.Improve the radiating efficiency of radiator, solved the phenomenon that the light fixture central temperature is gathered, the service life of the long light fixture in the court of a feudal ruler.
