Description
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.

Specific embodiment
In the present embodiment, be heat sink section bar at radiator 6, heat sink section bar is the hollow cylinder that the ultra-thin aluminium flake of the many muscle of camber line shape curves, and is distributed with vent rib 61 on it, as shown in Figure 4.
In the present embodiment, heat pipe 4 profiles are cylindric, be integral as Fig. 5, Fig. 6, shown in Figure 7 with circular aluminium flake 8,41 is vacuum in the cylinder, its lower end has with circular aluminium sheet 8 and joins, there is following screw thread 81 in the outside of circular aluminium sheet 8, and described heat pipe 4 is outer to be the heat sink section bar of institute's Roripa, tighten up a screw in the upper end of heat pipe 4 42 and power pack 7 be spirally connected.In light source 2 arranged outside aluminium circle 9 is arranged, aluminium circle 9 is spirally connected with the following screw 81 in circular aluminium flake 8 outsides.
In the present embodiment, the parts of heat radiation are not limited to heat sink section bar and heat pipe, and a lot of parts are heat conduction and heat radiation all.Such as reflection shield 5, power pack 7, aluminium circle 8 etc.
The heat radiation process of the heat abstractor of present embodiment is achieved in that led light source contacts with the fabulous aluminium base of heat conductivility earlier, and the heat of LED is passed to aluminium base fully, passes to circular aluminium block by aluminium base again, heat pipe, reflection shield, heat sink section bar, the heat abstractor of power pack etc.Heat abstractor comprehensive utilization contact conduction in the present embodiment, the principle heat radiation of heat loss through convection.In the present embodiment, heat pipe is a kind ofly to be made by the good aluminium of heat conduction, and interior is vacuum, and shape is moulding on demand, heat can be passed to heat sink section bar, reflection shield etc. fully; Many and the thin curve muscle of heat sink section bar vent rib in the present embodiment, area of dissipation is big, a kind of good heat-transfer device; Reflection shield area in this device is big, also can lead away a part of heat.Aluminium circle in the light source outside is dispersed into heat on the heat pipe.In the present embodiment, this device can effectively play thermolysis after tested, has guaranteed the service life of LED light fixture reliably.
