Jiangsu-born LIGHTING CO welcome you to consult the new rural LED solar street light LED street light factory direct smear Juan Ms. 18115103858 http://www.jianshengdy.com/ LED lights have a unique optical design, the LED street light shines on the area lighting need to further improve the efficiency of light in order to save energy. LED lights with environmental pollution, low power consumption, high luminous efficiency, long life and other characteristics that semiconductor LED street lights. It is based on a weak power semiconductor PN junction can be formed by high-efficiency solid-state light emitting source, in a certain forward bias voltage and the injection current injected into the P region of the hole and injecting electrons to the diffusion region N issued by the radiative recombination photons after the active region, the electrical energy directly into light. LED lights are widely used in major road projects, sports venues, squares, stations, terminals, tunnel lights and other outdoor lighting places LED lights features: energy conversion rate, compared with incandescent, energy efficiency up to 80 percent; long life The average life expectancy up to 50, 000 hours; low heat loss, without ultraviolet and infrared radiation; more high transmittance lens, light transmission rate of 85%. LED street light standards generally: 1, the conversion of light to 17% (the amount of solar energy per square 1000W, the actual utilization efficiency 170W). 2, the current market street lens material for improved optical materials, transmittance ≥93%, temperature -38- + 90 degrees. 3, LED street light lens, mainly for LED street light lens, spot rectangular material is PMMA optical materials, transmittance ≥93%, temperature -38- + 90 degrees, anti-yellowing UV UV `no rate 30,000 hours change. 4, the average intensity of road illumination uniformity 0.48. Spot ratio 1: 2. 5, in line with the road illumination. (Actually 1/2 central spot to reach 25LUX, 1/4 center light intensity reached 15LUX, 16 meters from the lowest light intensity 4LUX, overlapping light intensity of about 6LUX. 6, it has a very good application prospects in the new city lighting. Right depth of dimming, and the color and other characteristics do not change because of the dimming 7, adapted humidity:.. ≤95% Copyright http://www.jianshengdy.com/ (Jiansheng light industry) please indicate the source
