Description

LED lamp radiator
Technical field
The utility model relates to LED illuminating lamp technical field, refers in particular to a kind of LED lamp radiator.
Background technology
LED Chinese full name is a light emitting diode, a kind of semiconductor that electric energy can be converted into visible light.The LED illumination is the new industry that grows up recent years, the characteristics of LED illumination: the luminous efficiency height, and one two watts LED lamp is equivalent to the illuminating effect of one 15 watts ordinary incandescent lamp bulb; Long service life, LED lamp service life is the longest to reach 100000 hours; LED is a semiconductor element, compares with electronic energy-saving lamp with incandescent lamp, does not have sensing units such as vacuum device and high-voltage triggering circuit, and fault is extremely low, can freedom from repairs; Response time is short, has only for 60 sodium seconds, starts very rapid; Volume is little, in light weight.Utilize its characteristics can design the light fixture of not only thin, not only light but also compact all styles of; LED is bright in luster abundant.It is changeful that color saturation reaches the different photochromic combinations of 130% full color, utilizes sequential control circuit, more can reach colourful dynamic change effect; Harmful substances such as monochromaticjty is good, in the LED spectra collection, does not have spectrum such as unnecessary infrared, ultraviolet, and is not mercurous, heat, radiation seldom belong to typical green illumination light source, and discarded object is recyclable, do not pollute; Single led luminous flux is little.Single led luminous flux research level can reach 120lm/W at present, and the horizontal 75lm/W of industrialized product is flat luminous, high directivity.
As everyone knows, some are used for the high-power LED lamp of street and road and other area illuminations, and the heat that LED produced when lighting all is that the mode that adopts nature to distribute is dispersed into the space with heat usually, and the LED junction temperature is remained on the numerical value.Concrete grammar is earlier LED to be welded on the aluminium base that has circuit and an one deck thin dielectric layer, passes to lamp housing again by aluminium base and heat-conducting silicone grease then, and the fin by the lamp housing outside is dispersed into the space naturally with heat again, thereby reaches radiating effect.But, flange-cooled plate lamp housing is being deposited a lot of defectives, as: according to the requirement of LED heat dissipation characteristics, the power of LED light fixture is big more, the area of dissipation of light fixture is just big more, the reason that rises according to hot-air in addition, the cold and hot air in radiator edge flows easily, and the cold air of radiator core is not easy to obtain to replenish fully, make the convection current fast and effectively of cold and hot air, hindered distributing of core heat, caused the radiator central temperature to be higher than the unbalanced phenomena of lip temperature, thereby caused the LED junction temperature at radiator center to raise, surpassed LED and allow the junction temperature temperature, final LED brightness is decay or damage sharply, makes LED not reach the premium properties of the long service life that was had originally.
The utility model content
The purpose of this utility model is to provide the LED lamp that has the high efficiency heat radiation effect on a kind of LED of being used for lamp radiator.
The purpose of this utility model is achieved in that on the heat sink of radiator and is distributed with wire hole, draw-in groove, fin, inner groovy and waterproof bar, wire hole break-through heat sink, the waterproof bar is located at the inboard of draw-in groove, fin is evenly arranged on the heat sink, inner groovy is arranged on the another side opposite with fin, outer edge at inner groovy also is provided with a seal groove, and wire hole, draw-in groove and waterproof bar all are arranged on the place, two ends of inner groovy and fin.
The LED lamp radiator of high efficiency and heat radiation of the present utility model also comprises and has a following feature:
Edge at heat sink also is provided with the screw hole that is used for fixing usefulness;
In the draw-in groove inboard, the seal groove outside also is provided with a locating hole;
The length of described fin is greater than the width of heat sink.
Compared with prior art, LED lamp radiator of the present utility model is provided with draw-in groove, waterproof bar and fin and inner groovy, can realize installation and removal fast by draw-in groove, the assembling of realization modularization, being provided with of waterproof bar can be played an effective seal effect, compact arranged fin has increased the area of dissipation of heat sink, reach the effect of quick heat radiating, radiator and panel and lens and LEDLED have been satisfied in being provided with of inner groovy, the cooperation of power circuit and sealing, can play a good heat radiation by this structure, therefore effect such as waterproof and sealing is a kind of very outstanding LED lamp radiator.
Description of drawings
Fig. 1 is the perspective view of LED lamp radiator of the present utility model;
Fig. 2 is the another side perspective view of LED lamp radiator of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments LED lamp radiator of the present utility model is described further:
As depicted in figs. 1 and 2, LED lamp radiator body of the present utility model is a heat sink 1, comprises wire hole 11, draw-in groove 12, fin 13, inner groovy 14 and waterproof bar 15 at heat sink 1.Wire hole 11 break-through heat sinks 1, wire hole 11 are used for guide line and use.Draw-in groove 12 is located at the end of heat sink 1, and draw-in groove 12 is used for heat sink 1 and fixes effect with lamp housing.Waterproof bar 15 is located at the inboard of draw-in groove 12, and waterproof bar 15 is used for the water-tight effect.
As depicted in figs. 1 and 2, fin 13 is evenly arranged on the heat sink 1, and greatly to strengthen radiating effect, fin 13 has increased the area of dissipation of heat sink 1 to the length of fin 13 widely, can dispel the heat fast than the width of heat sink 1.Inner groovy 14 is arranged on the another side of the heat sink 1 opposite with fin 1, the panel and the LED lamp that can match with heat sink 1 in the inner groovy 14, inner groovy 14 can be provided with sealing device around to reach sealing effectiveness when matching with other part, edge at inner groovy 14 is provided with a seal groove 17, on the seal groove 17 water proof ring is housed, seal groove 17 is mainly used in the sealing between panel and the radiator.Edge at heat sink 1 also is provided with the screw hole 16 that is used for fixing usefulness, and screw hole 16 is evenly distributed on the edge of heat sink 1, but securing member such as attachment screw is used for the fixing of heat sink 1 on the screw hole 16.In draw-in groove 12 inboards, seal groove 17 outsides also are provided with a locating hole 18, locating hole 18 is distributed in the two ends of heat sink 1, when locating hole 18 is mainly used in assembling with connector location usefulness.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
