Description
Technical field
The utility model relates to a kind of high power reflective LED lamp, belongs to LED lamp technical field.
Background technology
The LED light fixture refers to that the light fixture product adopts light emitting diode (LED) technology as main light emitting source.LED is semiconductor light-emitting-diode, it is a kind of solid-state semiconductor element, it utilizes electric current forward to be passed to coupling place of semiconductor P-N knot, after being mutually combined by two kinds of carriers in hole of the electronegative electronics that separates in the semiconductor and positively charged again, and the generation photo emissions, between different types of LED can send from the infrared ray to the blue light, and purple light to the different wave length line such as between the ultraviolet ray.
The light distribution of light emitting diode (LED) is strong in the middle of being, all around a little less than, middle luminous intensity accounts for about 70% ~ 80% of total luminous intensity, luminous intensity all around accounts for total luminous intensity about 20% ~ 30%.The light direct projection of LED is out too dazzling, and people's direct-view is too dazzling, can form and dazzle the eyes.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of high power reflective LED lamp is provided, and forms the side bright dipping by the reflector reflection ray, the bright dipping better effects if, and illumination is softer.
According to the technical scheme that the utility model provides, high power reflective LED lamp comprises pedestal, chip, reflector and cored screw, it is characterized in that: reflector is fixed on the pedestal by cored screw, fixed chip on the pedestal.The pedestal center is provided with the louvre of perforation, and the reflector center is provided with the louvre of perforation.The louvre at the louvre at pedestal center and reflector center is interconnected.
Further, described chip is covered with lens.
Further, described reflector is outwardly semicircular arc face, and the inner surface of reflector is provided with a plurality of little curved surfaces.
Further, outwardly arc-shaped surface centered by the described reflector, the reflector inner surface arranges a plurality of glass microballoons.
Further, described cored screw center is provided with the louvre of perforation.
Further, described reflector adopts aluminium to make.
Further, the outside of described reflector is stuck in the groove of housing.
Further, described housing adopts aluminium to make, and has a plurality of equally distributed light output grooves on the housing.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Side bright dipping better effects if; Illumination is softer, can not dazzle the eyes.

The specific embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1, the utility model mainly comprises pedestal 1, chip 2, reflector 4 and cored screw 5, and fixed chip 2 is as light source on the described pedestal 1, and chip 2 is covered with lens 3, and the light that lens 3 are used for chip 2 is sent converges.Described reflector 4 is outwardly semicircular arc face, is fixed on the pedestal 1 by cored screw 5.Reflector 4 is used for the light reflection bright dipping of converging, and has avoided the dazzle the eyes phenomenon of direct projection bright dipping to eyes.Described pedestal 1 plays thermolysis.
Pedestal 1 center is provided with the louvre of perforation.Reflector 4 centers are provided with the louvre of perforation, and the louvre at the louvre at pedestal 1 center and reflector 4 centers is interconnected and has formed a heat dissipation channel.
Described lens 3 adopt optical glass to make.The inner surface of described reflector 4 is as reflecting surface, and the inner surface of reflector 4 is provided with a plurality of little curved surfaces, and a plurality of little surface compositions form a large curved surface, to reach the order ground of further soft light.Described reflector 4 adopts the reflectorized material aluminum with good heat radiating characteristic to do, and reflector 4 had both played reflection action, played again thermolysis.
Described cored screw 5 centers are provided with the louvre 7 of perforation, and louvre 7 forms a heat dissipation channel, and the air in the heat dissipation channel can form convection current, and the dissipation of heat that chip 2 sends is gone out.
Embodiment two as shown in Figure 2 is with the difference of embodiment one, outwardly arc-shaped surface centered by the described reflector 4, at reflector 4 inner surfaces a plurality of glass microballoons 6 that play the diffuse reflection effect are set, form mixed light again, so that bright dipping is softer.
Embodiment three as shown in Figure 3 also comprises the housing 8 that an aluminium is made, and the outer end of reflector 4 is stuck in the groove of housing 8 inboards.Have a plurality of equally distributed light output grooves 9 on the described housing 8, the light that goes out from reflector 4 side-irradiations sees through light output groove and shines out and form art up lighting effects.
The utility model is when work, and the rays pass through lens 3 that chip 2 sends is once proofreaied and correct, and then light relatively is evenly distributed on the reflecting curved surface of reflector 4 the further soft light of reflecting curved surface.The louvre 7 that cored screw 5 centers are provided with perforation forms a heat dissipation channel, and the air in the heat dissipation channel can form convection current, and the dissipation of heat that chip 2 sends is gone out.
