Technical field

The utility model relates to a kind of Projecting Lamp, especially relates to a kind of paster LED Projecting Lamp of adjustable rising angle of heat pipe band temperature controller.

Background technology

Existing Projecting Lamp is generally incandescent lamp, and is not energy-conservation, and the LED bulb is due to heat dissipation problem, and bulb life shortens; Paster LED also is called SMD LED, and its principle of luminosity is exactly that electric current is passed through compound semiconductor, and by the combination in electronics and hole, superfluous energy will disengage with the form of light, reach luminous effect.But existing paster LED is because rising angle is difficult to limit its application in some field or occasion greater than 160 degree, and its rising angle still is difficult to be equal to traditional incandescent lamp and electricity-saving lamp.

Summary of the invention

For the problem that above prior art exists, the purpose of this utility model is to provide a kind of paster LED Projecting Lamp of adjustable rising angle of heat pipe band temperature controller energy-saving and good heat dissipation effect.

the purpose of this utility model is to realize like this, the paster LED Projecting Lamp of the adjustable rising angle of described a kind of heat pipe band temperature controller, comprise the light projector lamp housing, supporting bracket and lamp socket, its design feature is that supporting bracket is positioned at light projector lamp housing bottom and is connected with light projector lamp housing lateral surface, in light projector lamp housing rear portion, lamp socket is installed, lamp socket is equipped with bulb, bulb comprises lamp holder and lamp outer casing, be provided with aluminium base in lamp outer casing, be provided with a plurality of paster LEDs and LED on aluminium base and drive chip, be connected with the little aluminium base of bending on aluminium base, the little aluminium base of bending is provided with paster LED, form angle between the little aluminium base of bending and aluminium base, aluminium base is covered with the glass outer cover, aluminium base is connected with the complex root heat pipe, be provided with temperature controller on aluminium base, paster LED connects LED and drives chip, opening part at the light projector lamp housing is equipped with the safety glass cover, and explosion-proof steel mesh is installed outside the safety glass cover.

The purpose of this utility model also can be achieved through the following technical solutions, the paster LED Projecting Lamp of the adjustable rising angle of described a kind of heat pipe band temperature controller, and its characteristics are for being provided with reflective silver strip in the light projector lamp housing.

The beneficial effects of the utility model are: the utility model is owing to adopting paster LED as luminescence unit, thereby can be energy-conservation.The utility model adopts an end of heat pipe to be connected with aluminium base, and aluminium base is connected with paster LED, has effectively solved the heat dissipation problem of LED lamp self by heat pipe, thereby has guaranteed that paster LED can work under low temperature.Be provided with temperature controller on aluminium base, make it to be unlikely to overheated and damage with protection LED lamp.The utility model also can adopt reflective silver strip, and pulling force is strong, and is high temperature resistant, non-friable, surperficial silver color, and minute surface is reflective, and the brightness spy is excellent, and surperficial minute surface is comparatively clear, and is reflective and radiation response is better, and its definition is near the chromatic effect that goes out of the true mirror of mercury.On the line, the LED luminescence unit is connected with LED and drives chip, and LED drives chip and adopts isolated constant current electronic to drive chip, and constant current electronic drives chip and adopts the imported from America constant current electronic to drive chip, has that efficient is high and the life-span long, energy-conservation texts.The utility model adopts the little aluminium base of bending can effectively enlarge the rising angle of LED light fixture, eliminates hot spot, dark space that traditional LED light fixture forms due to non-uniform light, thereby meets or exceeds the illumination effect of conventional incandescent, electricity-saving lamp.When taking into account Cost Design, effectively made up the shortcoming that existing LED light fixture rising angle is little, have the hot spot dark space.
