Description

A kind of paster LED Line lamp of adjustable rising angle of heat radiating type band temperature controller

Technical field

The utility model relates to a kind of Line lamp, especially relates to a kind of paster LED Line lamp of adjustable rising angle of heat radiating type band temperature controller.

Background technology

Existing Line 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 paster LED Line lamp of adjustable rising angle of heat radiating type band temperature controller energy-saving and good heat dissipation effect.

The purpose of this utility model is to realize like this, the paster LED Line lamp of the adjustable rising angle of described a kind of heat radiating type band temperature controller, comprise the messenger wire lamp holder, messenger wire, messenger wire lamp holder outer cover and lamp socket, its design feature is that lamp socket is arranged in the messenger wire lamp holder, messenger wire is located on the messenger wire lamp holder, messenger wire lamp holder outer cover is located at the Line lamp subfacies and is covered on outside the bulb, 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, forms angle between the little aluminium base of bending and the aluminium base, and paster LED drives chip with LED and is connected; Aluminium base is covered with the glass outer cover, and heat pipe one end connects aluminium base, the other end is connected with lamp outer casing; Outside heat pipe, be provided with radiating fin.

The paster LED Line lamp of the adjustable rising angle of described a kind of heat radiating type band temperature controller, its characteristics are for to be provided with temperature controller at aluminium base.

The beneficial effects of the utility model are: the utility model has energy-saving effect owing to adopt paster LED as luminescence unit.Aluminium base is connected with heat pipe, and the paster LED heat is transmitted to heat pipe through aluminium base, is provided with radiating fin outside heat pipe, strengthen heat pipe heat radiation, improve radiating effect, thereby guaranteed that paster LED can work under low temperature, prolonged the life-span of paster LED of the present utility model.Also can be provided with temperature controller at aluminium base, to protect the LED lamp to make it to be unlikely to overheated and to damage.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 by the little aluminium base of bending, 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.Effectively remedied the shortcoming that existing LED light fixture rising angle is little, have the hot spot dark space.
