Description

The rotating toilet of a kind of heat radiating type paster LED Mirror front lamp

Technical field

The utility model relates to a kind of Mirror front lamp, especially relates to the rotating toilet of a kind of heat radiating type paster LED Mirror front lamp.

Background technology

Existing Mirror front lamp is generally incandescent lamp or fluorescent lamp, and incandescent lamp is not energy-conservation, and fluorescent lamp does not have the LED bulb 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 rotating toilet of heat radiating type paster LED Mirror front lamp of adjustable rising angle energy-saving and good heat dissipation effect.

The purpose of this utility model is to realize like this, the rotating toilet of described a kind of heat radiating type paster LED Mirror front lamp, comprise fluorescent tube, tube stand and back plate, its design feature is that fluorescent tube places on the tube stand, tube stand and back plate are for being rotatably connected, fluorescent tube comprises fluorescent tube shell and glass outer cover, in the fluorescent tube shell, 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, forms angle between the little aluminium base of bending and the aluminium base, and paster LED connects LED and drives chip; It is outer and is connected with the fluorescent tube shell that the glass outer cover covers on aluminium base and paster LED, the refrigerant heat radiation chamber of dress refrigerant medium in aluminium base is connected with, and the refrigerant chamber of dispelling the heat is connected with the fluorescent tube shell through fin.

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 in aluminium base is connected with, refrigerant heat radiation chamber is connected with the fluorescent tube shell through fin, utilize decalescence and the heat release of the refrigerant medium in the refrigerant heat radiation chamber to carry out heat exchange, and through fin, fluorescent tube shell heat is dispersed into the external world, solved the heat dissipation problem of paster LED self effectively by the refrigerant medium, thereby guaranteed that paster LED can work under low temperature.Tube stand and back plate are convenient to regulate the tube stand angle of inclination for being rotatably connected; The glass outer cover covers on aluminium base and is connected outward and with the fluorescent tube shell with a plurality of paster LEDs, and the glass outer cover can carry out frosted to be handled, and it is soft to reach light.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 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 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.
