Description
Technical field
It the utility model is related to LED street lamp field, and in particular to a kind of environment-friendly street lamp of quick heat radiating.
Background technology
Street lamp, the light fixture that road provides illumination functions is showed, refers to the light fixture in the illumination zone of road surface in traffic lighting.In
State's street lamp storage is at 28,000,000-3,000 ten thousand.Newly-increased street lamp quantity was 15%-20% every year in recent years, about 3,000,000-600 ten thousand
Small cup.Calculated according to every 1000-2000 member, annual increment is in 3,000,000,000-60 hundred million yuans of market values, 2010-2015 compound year
It is 17.7% to spend growth rate.It will be apparent that the street lamp construction in China achieves development at full speed, road lighting quality constantly carries
Height, high-intensity gas discharge lamp are widely used, to improve China investment environment, promote rapid economic development, make things convenient for the people
Life, the construction of beautifying city and export-oriented modern city have played great role.
Traditional street lamp carries out 360 degree frequently with high-pressure mercury lamp and lighted, and the shortcomings that light loss is big causes the huge of the energy
It is big to waste.Currently, global environment is all developing clean energy resource in worsening, each state.And increase with the high speed of national economy
Long, China's energy supply and demand contradiction is outstanding day by day, and supply of electric power comes into existence the situation of critical shortage, and energy-conservation is is badly in need of solution
The problem of.Therefore, the LED street lamp efficient, energy-conservation, long lifespan, colour rendering index are high, environmentally friendly has very heavy to city illumination energy-conservation
The meaning wanted.Road lighting and people's production and living are closely related, and with the quickening of Urbanization in China, LED street lamp is with fixed
To it is luminous, power consumption is low, drive characteristic is good, fast response time, shock resistance are high, service life is long, the advantage such as green
Gradually enter into the visual field of people, as the energy-conserving light source of new generation of conventional light source advantage is most substituted, therefore, LED street lamp is
Optimal selection through being transformed as roadway illumination and energy saving.For LED street lamp unlike conventional street lamp, LED light source uses low-pressure direct
Stream power supply, the efficient white light synthesized by GaN base power-type blue-ray LED with yellow, have efficient, safety, energy-saving and environmental protection, life-span
The particular advantages such as length, fast response time, colour rendering index height, can be widely applied to different kinds of roads.It was predicted that before the year two thousand twenty, LED exists
The occupation rate of Chinese illumination market is up to 80%, and China will will surpass ten thousand as global maximum LED illumination market, market scale
Hundred million yuan.
But LED, because being semiconductor components and devices, its chip is influenceed by temperature and is reduced to the 30% of initial luminous flux
When, with regard to that will lose illumination meaning, that is, life termination, the life-span of high-power LED street lamp is in 3-5 ten thousand hours in theory, but
Its important prerequisite is that have good thermal diffusivity.Traditional LED street lamp designs major design emphasis on LED lumen number, and right
It is then less in the concern of radiating.In fact, with the continuous breakthrough of technology, existing LED lumen number rapidly rises,
Early in 2009, volume production LED single watt of lumen number reached 100 lumens, and is also rapidly increasing in recent years.But
The research for LED radiating is also rested in early stage level in the prior art, is mostly carried out by the way of heat conduction body heat transferring
Radiating is improved, its radiating effect is bad.
