Abstract
The utility model discloses a high-power light-emitting diode (LED) light source heat dissipation device, which comprises a high-power LED area light source, and is characterized in that: a vapor chamber is arranged at the rear part of the base of the high-power LED area light source, and heat dissipation fins are arranged at the rear part of the vapor chamber. In the high-power light-emitting diode light source heat dissipation device, the vapor chamber is adopted, so the heat dissipated by the high-power LED area light source is uniformly and quickly conducted and dissipated to the heat dissipation fins, accordingly, the temperature of an LED lamp bead is effectively controlled, the LED lamp bead is ensured to normally work, so the failure rate is effectively reduced. The high-power light-emitting diode light source heat dissipation device can quickly absorb the heat, conducts uniformly and has a good heat dissipation effect, so that the luminous efficiency of the LED light source is effectively improved, and the service life of an LED is prolonged, and the use reliability of the high-power LED area light source is improved.
Description
Technical field
The utility model relates to field of illuminating lamps, specifically is a kind of high-power LED surface light source heat abstractor.
Background technology
Led light source is as a kind of cold light source, because it has advantages such as energy-conserving and environment-protective, long service life, just is being widely used in increasing occasion and is doing the lighting source use.Present various white light LED lighting device mainly adopts the small-power white light LEDs to do.As the street lamp of the spot of the bulb of 1～5W, 15～20W and 40～60W, projecting lamp etc., these light fixtures have used tens to a hundreds of white light LEDs, complex manufacturing, poor reliability, fault rate height and luminance shortage.If change high-powerly, in case it is bad to dispel the heat, will cause the led light source luminous efficiency low, shorten the service life of white light LEDs, this also is the problem that LED lighting industry is faced.
Summary of the invention
The purpose of this utility model is the problem and shortage at above-mentioned existence, and a kind of raising LED surface source luminescence efficient is provided, the high-power LED surface light source heat abstractor that prolongs the service life of white light LEDs.
The technical solution of the utility model is achieved in that a kind of high-power LED surface light source heat abstractor, and its structure is to be provided with temperature-uniforming plate at the pedestal rear portion of high-power LED surface light source, and the temperature-uniforming plate rear portion is provided with fin.
Reliable and stable for guaranteeing syndeton, also improve radiating rate simultaneously, the connected mode of above-mentioned fin and temperature-uniforming plate can be to fixedly connected by welding manner.Fin also can be fixedlyed connected by filling highly heat-conductive material with temperature-uniforming plate.
Temperature-uniforming plate can be the lampshade rear portion that is fixed on led light source by welding manner, and stable to guarantee syndeton, the connection that it is seamless also improves radiating rate; Temperature-uniforming plate also can be to add the pedestal rear portion that screw fashion is fixed on led light source by filling highly heat-conductive material, with easy disassembly and maintain and replace light source.
For improving radiating effect, fin adopts punching press fin or section bar formula heat sink design.
The utility model has adopted temperature-uniforming plate, makes heat that high-power LED surface light source distributes evenly apace to fin conductive and distribute, thereby the temperature of LED lamp pearl is effectively controlled, and has guaranteed the operate as normal of LED lamp pearl chip, effectively reduces fault rate.The utility model heat absorption speed is fast and conduction is even, good heat dissipation effect, has effectively improved the led light source luminous efficiency, has prolonged the service life of LED, has improved the reliability that high-power LED surface light source uses.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model decomposition texture schematic diagram.
The specific embodiment
Below cooperate graphic and preferred embodiment of the present utility model, further set forth the specific embodiment of the present utility model.
As shown in Figure 1, 2, the utility model is a kind of high-power LED light source heat abstractor, comprises high-power LED surface light source 1, and the rear portion of high-power LED light source 1 is provided with temperature-uniforming plate 2, and temperature-uniforming plate 2 rear portions are provided with fin 3.Temperature-uniforming plate 2 and fin 3 adopt the copper of good heat conductivity or the material of aluminium alloy or other good heat conductivity to make.
During enforcement, fin 3 can be fixedlyed connected by welding manner with temperature-uniforming plate 2, and fin 3 also can be fixedlyed connected by filling highly heat-conductive material with temperature-uniforming plate 2.Temperature-uniforming plate 2 is fixed on the rear portion of led light source 1 by welding manner.Temperature-uniforming plate 2 also can be fixed on the lampshade rear portion of led light source 1 by screw fashion.As shown in Figure 1, the utility model preferred embodiment fin 3 and temperature-uniforming plate 2 are fixed on the rear portion of led light source 1 by welding manner.
The thickness of temperature-uniforming plate 2 is between 3mm-8mm.Its one-tenth-value thickness 1/10 and size and shape are decided according to lamp power and size and shape, and as shown in Figure 1, 2, the utility model temperature-uniforming plate 2 is arranged to square, and the base of fin 3 also is arranged to square.Fin 3 is designed to the fin shape, designs the ratio of fin pitch and height, makes the cooling surface area of led light source 1 can be corresponding with power number.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
