Description

A kind of explosion-proof Projecting Lamp of paster LED of the adjustable rising angle with heat eliminating medium

Technical field

The utility model relates to a kind of Projecting Lamp, especially relates to a kind of explosion-proof Projecting Lamp of paster LED of the adjustable rising angle with heat eliminating medium.

Background technology

Existing Projecting Lamp is generally incandescent lamp, and is not energy-conservation, and the LED bulb is because 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

At the problem that above prior art exists, the purpose of this utility model provides a kind of explosion-proof Projecting Lamp of paster LED of adjustable rising angle of band heat eliminating medium energy-saving and good heat dissipation effect.

The purpose of this utility model is to realize like this, the explosion-proof Projecting Lamp of paster LED of described a kind of adjustable rising angle with heat eliminating medium, comprise the light projector lamp socket, light projector lamp housing and lamp socket, its design feature is for being provided with reflective silver strip in the light projector lamp housing, in the light projector lamp socket lamp socket is installed, lamp socket is equipped with bulb, bulb comprises lamp holder and lamp outer casing, in lamp outer casing, be provided with aluminium base, aluminium base is provided with a plurality of paster LEDs and LED drives chip, be connected with the little aluminium base of bending at aluminium base, the little aluminium base of bending is provided with paster LED, form angle between the little aluminium base of bending and the aluminium base, be covered with the glass outer cover at aluminium base, the refrigerant heat radiation chamber of dress refrigerant medium in aluminium base is connected with; Paster LED connects LED and drives chip; In light projector lamp housing bottom the safety glass cover is installed, explosion-proof steel mesh is installed outside the safety glass cover.

The beneficial effects of the utility model are: the utility model is owing to adopt paster LED as luminescence unit, thereby can be energy-conservation.The refrigerant heat radiation chamber of dress refrigerant medium had solved the heat dissipation problem of LED lamp self effectively by the refrigerant medium in aluminium base of the present utility model was connected with, thereby had guaranteed that paster LED can work under low temperature.Adopt reflective silver strip, pulling force is strong, and is high temperature resistant, non-friable, surperficial silver color, and minute surface is reflective, and brightness is more excellent, and surperficial minute surface is comparatively clear, and is reflective and radiation response is preferable, 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 electric drive chip, and constant current electric drive chip adopts U.S.'s import constant current electric drive chip, has effects such as efficient height and life-span be long, energy-conservation.The utility model can effectively enlarge the rising angle of LED light fixture, eliminates hot spot, dark space that traditional LED light fixture forms owing to non-uniform light, thereby meets or exceeds the illumination effect of conventional incandescent, electricity-saving lamp.When taking into account into the design, effectively remedied the shortcoming that existing LED light fixture rising angle is little, have the hot spot dark space.
