Lamp is regulated in a kind of LED reflection, it is characterized in that: comprise two led light sources, a sun-shading cap, two heat-conducting plates, a reflector, a radiator, led light source is fixed by heat conduction onboard led locating slot, two heat-conducting plates directly are connected with radiator, in radiator inside reflector has been installed, reflector is socketed on the heat-conducting plate, and led light source reflector central vertical axis angle is 2 °, and sun-shading cap is located at the heat-conducting plate top and the sun-shading cap locating hole on reflector is fixed.
Described two heat-conducting plates, mainly be to constitute by locating hole, LED locating slot, its profile is the L type, L horizontal direction face is an arc surface, the above-below direction face is a trapezoidal faces, two led light sources are fixed through being glued at two heat-conducting plate trapezoidal faces LED locating slots by the led light source panel respectively, rivet together by radiator reference column and radiator, perhaps by gummed that heat-conducting plate arc surface and radiator gummed is in aggregates together, the heat that led light source produces is by dispelling the heat on heat-conducting plate and the transmission radiator thereof.Reflex to area on the reflector in order to increase led light source, the arc surface of heat-conducting plate and trapezoidal faces angle are made 92 °, thereby the light that makes two led light sources produce has part to intersect in the central area, therefore can avoid the irradiation area of heat-conducting plate correspondence to produce blind spot.
Described reflector, form by reflecting piece, sun-shading cap locating hole, dowel, its reflecting piece is arranged the inner surface recesses that constitutes and is parabolic shape, shape and radiator inner groovy match, reflector is enclosed within on the heat-conducting plate, twists by the reflector locating hole on the connection of the dowel on the reflector radiator to lump together.Inner surface recesses that according to actual needs can the accommodation reflex cup is the size of parabolic shape groove, needs the light source for reflection illumination that the visual angle is suitable, the light source scope is suitable to obtain practical application.The optically focused effect of the light process reflector of led light source reflects and obtains the illumination light that light is soft, scope is suitable.
Described radiator, its interior shape and reflector parabolic shape match, the bottom by with two corresponding disks of heat-conducting plate and reference column, and corresponding reflector locating hole is so that and heat-conducting plate, reflector fixing.The outside of radiator is the arc shape radiator shutter, and direction is arranged in the same way, so good heat dissipation effect, and the transmission heat that passes through heat-conducting plate that can in time led light source be produced is evacuated.
Described sun-shading cap is enclosed within above the heat-conducting plate, and two ends cooperate fixing by sun-shading cap locating hole above the reflector.Sun-shading cap can cover the direct light of LED lamp, and the light that makes LED come out by reflector is soft reverberation, thereby avoids dazzle, reaches the purpose of protection human eye.
Described heat-conducting plate, its composition material of radiator can be aluminium, aluminium alloy, copper and combination thereof, and described reflector, its composition material of sun-shading cap can be aluminium, aluminium alloy.
The invention has the beneficial effects as follows: have that optically focused is good, heat-sinking capability is strong, can not produce dazzle, be fit to applications such as family room's intraoral illumination, street lighting.
