Description

Six passage heat pipes coupling via hole radiator LED street lamp

Technical field

This utility model relates to a kind of LED street lamp, particularly a kind of LED street lamp of heat pipe coupling via hole radiator.

Background technology

The core technology of semiconductor lighting is luminous intensity distribution, driving and heat radiation, and wherein heat dissipation technology is the key factor that determines the working life of lighting.The working life of LED luminescence chip can reach 50,000 hours, if but the lighting of forming as high-power integrated chip does not have enough heat abstractors, its working life does not reach 50,000 hours far away, if radiator structure is unreasonable, the useful life of a light fixture often had only about 10,000 hours.Therefore high-power LED lamp is used for road lighting, and the research of lamp cooling structure is one of current core technology.The breakthrough of heat dissipation technology just can bring the life-span that prolongs light fixture just can really reach the purpose of the energy-saving and emission-reduction of lighting field, and the energy-saving effect of LED street lamp just can be realized than the target of traditional sodium Lantern Festival energy 30% ~ 50%.

The tradition high-power LED street lamp divides two class forms.One class is that the LED device by many 1W to 3W is evenly distributed on the aluminium base, cover on the aluminium radiator by heat-conducting silicone grease, the heat radiation of this type of light fixture is more even, but owing to use nearly more than 100 of LED number, just need be made up of more than 100 lens, these type of lens, use the PC material now, use easy flavescence of a period of time, influence light transmittance, so the structural manufacturing process complexity, cost is very high.Another kind of high-power integrated LED device, power are between 30W ~ 100W, and every light fixture is formed a light fixture by 1 to 3 integrated device and via hole radiator structure usually.Therefore whole light fixture only needs 1 to 3 glass lens, need not to add the glass that keeps off the rain, so this class Luminaire efficiency is expensive low again, and the simple energy-saving effect of technology is better than top first kind light fixture.

But the subject matter that the integrated chip LED light fixture of this second class exists is the centre that chip temperature all concentrates on aluminium base or via hole radiator, therefore the entire heat dissipation system temperature difference is very big, the centre have 70 the degree ~ 80 the degree and periphery have only 40 the degree ~ 50 the degree, therefore radiating effect is poor, cause local temperature can not be transmitted to peripheral aluminium fast, the final useful working life that influences light fixture, how to solve Temperature Distribution, reaching even quick heat radiating, is the technical bottleneck that high-power integrated chip LED street lamp, Tunnel Lamp, High-Pole Lamp face.

Summary of the invention

Goal of the invention: the purpose of this utility model provides a kind of evenly quick heat radiating to improve the six passage heat pipes coupling via hole radiator LED street lamp of light fixture working life.

Technical scheme: a kind of six passage heat pipes coupling via hole radiator LED street lamp, comprise lampshade, be installed in driving box, led chip, heat-radiating substrate, fin, lens and the pressure ring of lampshade one side, described led chip is fixedly mounted on the center of lampshade successively by heat-radiating substrate and fin, described fin is that network structure is connected with the lampshade inwall, described heat-radiating substrate is fixed on the center of netted fin, described lens are fixed on the heat-radiating substrate by pressure ring, and described led chip is sealed between lens and the heat-radiating substrate; Be provided with at least two heat pipes between described heat-radiating substrate and the netted fin, described heat pipe one end connects on the heat-radiating substrate of led chip center, and the described heat pipe other end prolongs fin and extends to lampshade.

In order further to improve radiating effect and the hot uniformity, the quantity of described heat pipe is the six roots of sensation, is evenly distributed on heat-radiating substrate and is the divergent shape distribution all around.

Described heat pipe diameter is 10mm, and length is 20-40cm.

Beneficial effect: 1, radiating efficiency of the present utility model doubles than traditional LED street lamp; 2, hot uniformity average out to 90%; 3, be particularly suitable for the high-power integrated LED lamp tool and use, reduced cost, prolonged service life.
