Description
Technical field
The present invention relates to infrastructure control field, particularly relate to a kind of LED street lamp intelligent control based on ZigBee.
Background technology
Road lighting is the important component part of city illumination, and traditional street lamp often adopts, and high-pressure sodium lamp 360 degree of luminescences, the shortcoming that light loss is large causes the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at 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, supply of electric power comes into existence the situation of critical shortage, and energy-conservation is institute's urgent problem.Therefore, development of new is efficient, energy-conservation, the life-span is long, color rendering index is high, the LED street lamp of environmental protection is of great significance the energy-conservation tool of city illumination.
Road lighting and people's productive life closely related, along with the quickening of Urbanization in China, LED street lamp with directional lighting, the advantage such as power consumption is low, drive characteristic good, fast response time, shock resistance are high, long service life, environmental protection enter into gradually people the visual field, become the energy-conserving light source of new generation most in the world with alternative conventional light source advantage, therefore, LED street lamp will become the optimal selection of roadway illumination and energy saving transformation.
LED street lamp and conventional street lamp unlike, LED light source adopts low-voltage DC supply, by GaN base power-type blue-ray LED and the yellow efficient white light synthesized, there is the particular advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, color rendering index height, can road be widely used in.Outer cover with making, high temperature resistantly can reach 135 degree, low temperature resistantly reaches-45 degree.
LED street lamp is compared with conventional road lamp, and tool has the following advantages:
1, characteristic---the one-way of light own, does not have the diffusion of light, ensures light efficiency.
2, LED street lamp has unique secondary optical design, the illumination of LED street lamp is mapped to the region of required illumination, further increases light efficiency, to reach energy-conservation object.
3, LED reach 110-130lm/W, and also have very large development space, theoretical value reaches 360lm/W.And the luminous efficiency of high-pressure sodium lamp just increases to some extent with power increase, therefore, overall light efficiency LED street lamp is stronger than high-pressure sodium lamp; (this overall light efficiency is theoretic, and in fact the light efficiency of more than 250W high-pressure sodium lamp is higher than LED).
4, the light color rendering of LED street lamp is more much higher than high-pressure sodium lamp, and high-pressure sodium lamp color rendering index only has about 23, and LED street lamp color rendering index reaches more than 75, consider from visual psychology angle, reach equivalent brightness, the illuminance of LED street lamp on average can reduce by more than 20% than high-pressure sodium lamp.
5, light decay is little, and the light decay of a year, less than 3%, uses and still reaches rto request in 10 years, and high-pressure sodium lamp light decay is large, within about 1 year, has declined more than 30%, and therefore, LED street lamp can be lower than high-pressure sodium lamp in the design using power.
6, LED street lamp has automatic control energy-saving device, can realize at the reduction power meeting maximum possible in Different periods lighting requirement situation, saves electric energy.Can realize computer light modulation, time segment controls, and light controls, and temperature controls, the hommization functions such as automatic detecting.
7, the life-span is long: can use more than 50,000 hours, provides the quality assurance of 3 years.Weak point is exactly can not be guaranteed in life-span of power supply.
8, light efficiency is high: the chip of employing >=more than 100LM, relative to conventional high-tension sodium vapor lamp energy energy-conservation more than 75%.
9, simple installation: bury cable without the need to rectifier etc. without the need to adding, directly will be installed on lamp stand and to connect or by nested for light source original lamp housing.
10, radiating control is outstanding: summer temperature controls below 45 degree, and adopts passive radiating mode, and the heat radiation in summer ensures not enough.
11, reliable in quality: circuit power all adopts high-quality components and parts, every LEDs has independent overcurrent protection, without the need to fear of damage.
12, evenly photochromic: not add lens, do not sacrifice evenly photochromic to improve brightness, thus ensure evenly photochromic without aperture.
13, LED is not containing harmful mercury metal, can not work the mischief when scrapping to environment.
14, maintenance cost is low: relative to conventional road lamp, and LED street lamp maintenance cost is extremely low, through comparing, is recoverable whole input cost less than 6 years.
Existing LED controls to be substantially all directly by cable switch control rule, the brightness of LED is by the fixing voltage of LED street lamp itself and LED bulb decision itself, even if there is the system that can adjust its brightness, also be all by laying a large amount of cable to control, input cost is very large, and is unfavorable for maintenance.
