Description
Technical field
The present invention relates to a kind of street lamp, especially the LED street lamp.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is big has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is institute's urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, colour rendering index is high, the LED street lamp of environmental protection has a very important meaning to city illumination is energy-conservation.
Road lighting and people's productive life are closely related, quickening along with Urbanization in China, advantages such as the LED street lamp is luminous with orientation, power consumption is low, drive characteristic good, response speed is fast, shock resistance is high, long service life, environmental protection enter into gradually people the visual field, become the energy-conserving light source of new generation that has alternative conventional light source advantage in the world most, therefore, the LED street lamp will become the optimal selection that roadway illumination and energy saving is transformed.
Technological merit has at present:
1, the characteristic of LED street lamp---the one-way of light itself does not have diffusion of light, guarantees light efficiency.
2, the LED street lamp has unique secondary optics design, and the illumination of LED street lamp is mapped to the zone of required illumination, has further improved light efficiency, to reach energy-conservation purpose.
3, the source efficiency of LED has reached 110-130lm/W, and also has very big development space, and theoretical value reaches 250lm/W.And the luminous efficiency of high-pressure mercury lamp is just to increase to some extent with the power increase, and therefore, the overall light efficiency LED street lamp is stronger than high-pressure mercury lamp; (this overall light efficiency is theoretic, and in fact the light efficiency of the above high-pressure mercury lamp of 250W is higher than LED).
4, the light colour rendering of LED street lamp is more much higher than high-pressure mercury lamp, the high-pressure mercury lamp colour rendering index has only about 23, and LED street lamp colour rendering index reaches more than 75, consider from the visual psychology angle, reach equal brightness, the illuminance of LED street lamp on average can reduce more than 20% than high-pressure mercury lamp, (with reference to Britain's road illumination standards).
5, light decay is little, and the light decay in 1 year use still to reach road use illumination requirement in 10 years, and the high-pressure mercury lamp light decay is big, has descended about 1 year more than 30% less than 3%, and therefore, the LED street lamp can be lower than high-pressure mercury lamp in the design of using power.
6, the LED street lamp has automatic control energy saver, can be implemented in the reduction power that satisfies maximum possible under the different period lighting requirement situations, saves electric energy.The Spark intelligent LED street lamp can be realized the computer light modulation, time segment control, and light control, temperature control, Long-distance Control such as patrols and examines automatically at the hommization function.
7, LED is low-voltage device, the voltage that drives single LEDs is safe voltage, series of products list LEDs power all is 1 watt, use the safer power supply of high voltage source so it is a ratio, be specially adapted to public place (for example: street lighting, factories and miness illumination, automotive lighting, domestic lighting etc.).
8, each unit LEDs small pieces has only very small size, thus can be prepared into the device of different shape, and be suitable for variable environment.
9, the life-span is long: can use more than 50,000 hours, the quality assurance in 3 years is provided.Weak point is exactly to can not get in life-span of power supply guaranteeing.
10, the above chip of light efficiency height: employing 〉=100LM can be energy-conservation more than 75% with respect to the conventional high-tension sodium vapor lamp.
11, simple installation: need not to add and bury cable and need not rectifier etc., directly road lamp cap is installed on that lamp stand connects or with the nested original lamp housing of light source.
12, radiating control is outstanding: summer temperature is controlled below 45 degree, and adopts passive radiating mode, and the heat radiation in summer ensures not enough.
13, reliable in quality: circuit power all adopts the high-quality components and parts, and every LEDs has independent overcurrent protection, need not to worry to damage.
14, photochromic evenly: do not add lens, do not sacrifice to improve brightness evenly photochromic, thereby guarantee that no aperture is photochromic even.
15, LED does not contain harmful mercury metal, environment is worked the mischief when scrapping unlike high-pressure mercury lamp or metal halide lamp.
Comprehensive above-mentioned principle, the energy-saving effect of high-power LED street lamp is remarkable, replaces high-pressure mercury lamp to economize on electricity more than 60%.(remaining to be investigated)
Maintenance cost is low: with respect to conventional road lamp, LED street lamp maintenance cost is extremely low, through relatively, is recoverable whole input cost less than 6 years.
But the problem of technology existence at present has:
1. single led power is low.High-power in order to obtain, need a plurality of in parallel uses.
2. colour rendering index is low.
3. hot spot.
4.LED irradiation uniformity problem
5.LED the light decay problem
6. there is not auto-switch function.
