Technical field

The utility model relates to a kind of lighting, particularly a kind ofly will make the bulkhead lamp capable of light source of light emitting diode.

Background technology

Light emitting diode (light-emitting diode LED) can send the light of certain brightness, and brightness can be regulated by electric current or voltage again, and itself is shock-resistant again, anti-vibration, and glow color is very abundant, and the transition of color is very soft.Simultaneously service life long especially, it is reported life-span of LED lamp be ordinary incandescent lamp 20-30 doubly, be more than 10 times of conventional fluorescent lamps life-span.The LED lamp is because there is advantage such as energy-saving and environmental protection, so the LED lamp becomes the main force of city lighting, also more and more uses on the lighting simultaneously.Current general bulkhead lamp capable only directly contacts etc. as heat abstractor with aluminium section bar and thermal source, and heat dissipation conductor quantity is little, and contact area is little, and heat dispersion is bad.Particularly less when the thermal source area, when the aluminium section bar area was big, thermal source can not directly contact fully with heat sink section bar, all heats of thermal source can not be led away fully, and light source life is reduced greatly.So traditional heat abstractor is being inapplicable in some cases, can not guarantee the service life of led light source.

Summary of the invention

In order to overcome the above-mentioned deficiency of bulkhead lamp capable in the prior art, the utility model provides a kind of LED bulkhead lamp capable, increases heat radiation, heat conduction and contact area, improves heat dispersion, guarantees the service life of thermal source.

The utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of LED bulkhead lamp capable with heat abstractor, comprise high-power LED light source, reflection shield, heat abstractor and power pack, reflection shield covers on outside the light source, and heat abstractor is arranged between power pack and the light source; Described heat abstractor comprises heat pipe, fin, circular aluminium sheet and heat conduction substrate, heat pipe is the metal tube of a hollow, described fin is set outside it, one end is connected with described power pack, the described circular aluminium sheet of another termination closely links to each other with described circular aluminium sheet while described heat-conducting substrate is installed described light source

The beneficial effects of the utility model are, owing to be provided with a heat-conducting substrate between light source and heat pipe, this heat conduction substrate is made by the fabulous aluminium base of heat conductivility, in the time of above light source is installed to, to pass by to change from face heat conduction, and increase area of dissipation greatly and strengthen heat radiation by light source point heat conduction.
