Background technology
LED is the very little semiconductor devices of a kind of profile, when electric current can send versicolor light during by it.Glow color depends primarily on the chemical composition of the luminous composition of led chip, can be deployed into as required that white light or other are various coloured light.Recently, use high-power LED light source to begin as decoration and lighting source, the lighting apparatus of led light source uses the white light LEDs or the white light that produce by three primary colours RGB all having undesirable phenomenon as the employed general reflector of light source aspect lighting effect, the light uniformity and the hot spot in certain zone, and the emission angle of the light that high-power LED light source sends and hot spot do not reach expection sometimes.Along with science and technology develops day by day at high speed, large-power light-emitting diodes (High Power LED) obtains constantly progressive and extensive use as decorating with lighting source, and led light source does not have that mercury is nontoxic, power requirement is low, no electromagnetic pollution, no harm ray, cold light source etc.Because large-power light-emitting diodes LED itself is a spot light, light shafts concentrate on a bit, and are very dazzling, allow the people feel under the weather, and can not form the needed hot spot of people.But large-power light-emitting diodes LED is clean environmental protection light source, is more and more paid attention to and accepts by people.
Based on the weak point of above-mentioned general high-power LED light source, the inventor has designed the utility model " a kind of reflector that is used for high-power LED light source ".
The utility model content
The utility model at above-mentioned the deficiencies in the prior art technical problem to be solved is: a kind of reflector that is complementary and uses with high-power LED light source is provided, it can further strengthen the lighting effect and the light uniformity in certain zone, and forms the hot spot of definite shape.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of reflector that is used for high-power LED light source, reflector is to be mounted on the high-power LED light source and with screw by draw-in groove that itself is provided with and positioning bar to be fixed on the compressing tablet, high-power LED light source also is fixed on the compressing tablet with screw, compressing tablet and radiator are provided with semicircle groove, heat pipe is mounted in its semicircle groove, and fix with screw, the heat pipe that high-power LED light source and compressing tablet binding face and compressing tablet and radiator fit is accepted face and is all scribbled thermal grease, reflector is by the ABS micelle integral injection mo(u)lding of high-quality, inner surface is vacuum aluminum-coated, form good secondary optics reflector, its inner surface is provided with several micro-structural curved surfaces, cup end on one's body is provided with a glass edge, and cup body both sides are provided with the screw hole post, and cup body lower end is provided with draw-in groove and positioning bar.The integral injection mo(u)lding have several micro-structural curved surfaces by required design permutation and combination can obtain required hot spot and lighting effect, several micro-structural curved surfaces can be that triangle, rhombus, trapezoidal and quadratic surface constitute.The light that high-power LED light source sends is mapped on the micro-structural curved surface, just can form the hot spot of definite shape through the micro-structural camber reflection, and as rectangular light spot, the light uniformity and utilization ratio of optical energy all are improved.Because the optical characteristics of reflector, the geometric parameter and the micro-structural curved surface parameter of change reflector just can be regulated the angle of departure of high-power LED light source secondary light, also just change lighting effect and the light uniformity and the light spot shape of high-power LED light source secondary light.
A kind of reflector beneficial effect that is used for high-power LED light source of the utility model is:
(1) the utility model has solved the dazzle of high light large power LED light source, because large-power light-emitting diodes LED itself is a spot light, light shafts concentrate on a bit, very dazzling, allow the people feel under the weather, can not form the needed hot spot of people, the reflector design has certain height, form and cut light, the inner surface design has several secondary optics micro-structural curved surfaces, and the light that high-power LED light source sends is mapped on the micro-structural curved surface and reflects, form the definite shape hot spot, whole light is softer, and brightness is moderate, light respond well, improved utilization ratio of optical energy, the reflector design makes integral body compacter, and is more harmonious, more attractive in appearance.
