Description
Technical field
The present invention relates to a kind of LED street lamp.
Background technology
The energy consumption of lighting field accounts for 20% of whole electric energy, and that common illuminating lamp only has 30% electric energy to be used for is luminous, and all the other have changed into heat energy and have distributed to the external world.The heat that LED produces during because of its work is less, and luminous efficiency is higher, is regarded as cold light source.The LED street lamp is made up of substrate, lens and the cooling system etc. of band LED, compares with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%.Since it is born,, more and more be subjected to the attention of countries in the world with its efficient low-consume, energy-conserving and environment-protective, long characteristics of life-span.China is used for the electric power of street lighting present every year near 2,500 hundred million degree, and wherein if can have 1/3 to adopt the LED street lighting, annual just can the economize on electricity about 80,000,000,000 degree is equivalent to the annual electricity generating capacity in power station, Three Gorges basically.
Though LED is regarded as cold light source, still can produce certain heat during work.The operating temperature of LED generally should be less than 50 ℃.There is data to show that when the operating temperature of LED reaches 55 ℃, its life-span will reduce half.The heat radiation system of present LED street lamp is imperfection very, has become it and has applied stumbling-block in the process, and is even more serious for middle this kind of high-capacity LED street lamp situation.Therefore heat dissipation technology has become one of main direction of studying of person skilled.
Street lamp is in outdoor environment for a long time, requires waterproof and dustproof, protection against insect on the structure, and its lampshade must be the cavity of a sealing.The LED of LED street lamp will work in the environment of sealing equally, and this just means that it can't can only outwards dispel the heat by lampshade by cross-ventilation directly to external world's heat radiation.For this reason, some technical staff is provided with fin at substrate back, and the heat that LED is sent in time is dispersed in the air by fin.Limited but the lampshade inner space is sealed, can't form effective convection current, the heat transfer coefficient of air is low again, so this LED street lamp is only very fast to the heat radiation of fin from LED, and very slow from fin to external world's heat radiation, can't adapt to the long-term work requirement of street lamp.
