High-power LED street lamp requires structurally good heat dissipation effect, is because the photoelectric conversion rate only about 35% of LED, though in recent years increasing, but the most limited, remaining is then converted to electric heating, forms higher junction temperature, so that causing the light decay of LED, and then shortens its life-span.The form of heat radiation includes the conduction of heat, the flowing of heat and radiation of heat, and currently, LED street lamp lays particular emphasis on the conduction of heat on heat dissipation technology designs mostly, to strengthen physical quantity and to expand the specific surface area of heat radiation in design.The thermal energy conduction that produces during LED operation to after on radiator, can only be leaned on natural diffuseness to be distributed in air slowly by heat energy by this heat conduction structure, and radiating effect is the most very good.The further raising of current LED industry urgent needs heat dissipation technology, to reduce junction temperature, reduces light decay.
Attention energy-saving and emission-reduction worked along with country and the urgency of reducing energy consumption, most of areas are all using LED street lamp, but LED street lamp product has problems in many aspects, such as: light decay, heat radiation, light capabilities etc., this allows for roadway illumination and there is a lot of problem, thus affects road safety.
(1) heat dissipation problem
Street lamp is with out of doors, accomplish waterproof and dust-proof, so light fixture must seal, after sealing in light fixture the temperature of water vapour in the case of extreme climate more than 100 degree, LED works in the environment of such high temperature continuously, if LED street lamp thermal diffusivity is bad, light fixture is serious with regard to as easy as rolling off a log damage or light decay, causes product follow-up maintenance cost to increase.The heat dissipation problem of domestic high-power LED street lamp is fully solved not yet.
(2) illuminance is not enough
The electric energy saved under energy-conservation i.e. equal average illumination, this average illumination can not be only ground average illumination, the light intensity in space has anticipation the most in advance for the vehicle sailed at a distance, prevents traffic accident from occurring, and domestic installed LED street lamp is all to sacrifice illuminance to reach energy-conservation.
Summary of the invention
