Supply Daqing rural road LED lights

Features LED lights with conventional high pressure sodium lamps is different, high-power LED street lamp light source using low voltage DC power supply, power-type GaN-based blue LED with yellow phosphor white LED efficient synthesis, efficient, safe, energy-saving, environmental protection, life long, fast response, unique advantages of high color rendering index, can be widely used in urban road lighting. Housing available PC pipe production, high temperature of 135 degrees, low temperature up to -45 degrees. Light-emitting diodes (LightEmittingDiode, abbreviated as LED) is based on a weak power semiconductor PN junction is formed of highly efficient solid state light source can emit light at a certain forward bias voltage and injection current injection region and the injection hole P N electron diffusion region in the active region to emit photons by radiative recombination, electricity directly into light. 3 Advantages 1, LED lights own characteristics - light, one-way, no light diffusion, guarantee lighting efficiency. 2, LED lights have a unique optical design, LED lights will light shines on the desired area lighting, and further improve the efficiency of light in order to save energy. 3, LED light source efficiency reached 110-130lm / W, but there is still much room for development, the theoretical value of 360lm / W. High pressure sodium lamp luminous efficiency is increased with the increase in power have, therefore, the overall luminous efficiency LED lights stronger than high-pressure sodium; (the overall light efficiency is theoretically, in fact, more than 250W high pressure sodium lamp luminous efficiency is higher than the LED) . 4, LED street light color than high pressure sodium lamp many, high pressure sodium lamp color rendering index of only 23, while the LED lights color rendering index of 75 or more, from the viewpoint of visual psychological point of view, to achieve the same brightness, illumination LED lights mean you can lower than the high pressure sodium lamp more than 20% (see the British lighting standards). 5, light is small, light failure a year less than 3%, with 10 years still to reach road use illumination requirements, and high-pressure sodium light fades large, about a year has fallen by more than 30%, therefore, LED lights in the use of power the design can be lower than the high pressure sodium lamps. 6, LED lights with automatic control energy-saving devices, can be implemented in time to meet the lighting requirements of different circumstances the maximum possible reduction in power and save energy. Spark LED lights can achieve computer intelligent dimming control sub-period, light control, temperature control, remote control, automatic inspection and other user-friendly features. 7, LED are low voltage, single LED drive voltage is safe voltage, series single LED power is 1 watt, so it is a more secure than the use of high voltage power supply, especially for public places (for example: street lighting, industrial lighting, automotive lighting, commercial lighting, etc.). 8, each LED die unit only a small volume, it can be prepared into various shapes of devices, and for the environment variable. 9, long life: can be used for more than 50,000 hours, provide three years of quality assurance. Deficiencies is the power of life can not be guaranteed. 10, high luminous efficiency: using ≥100LM more chips, as opposed to traditional high pressure sodium lamp can save more than 75%. 11, installation is simple: no Jiamai cable without rectifiers, etc., directly to the street light poles installed in or connected to the original light source nested shells. 12, excellent thermal control: summer temperature at below 45 degrees, and the use of passive cooling, lack of summer heat protection. 13, reliable: the power supply circuit used in all high-quality components, each LED has a separate over-current protection, without fear of damage. 14, light color uniform: without lens, not to increase the brightness at the expense of uniform light color, so as to ensure no aperture light color uniform. 15, LED does not contain harmful metal mercury, unlike high pressure sodium or metal halide lamps at end of life damage to the environment. The above principle, the energy saving effect of high-power LED lights significantly, replace the high pressure sodium lamp can save more than 60%. (To be fine) low maintenance costs: Compared with traditional lights, LED lights very low maintenance costs, by comparison, less than six years to recover the full cost of inputs.
