Lanzhou streetlight manufacturers, Lanzhou street price

Lanzhou streetlight manufacturers, Shaanxi King Cheng Lighting Factory, 2015 latest masterpiece, the latest research and development and production of national scientists and technical workers in the field of lighting one of the most recognized energy saving, environmental protection, new light -LED lights, street lights manufacturers as a luminous Lanzhou material, compared to other light-emitting materials, with its green, energy efficient, safe and reliable, rich colors, durability and longevity advantages, Shaanxi Jing Cheng QQ: 2489503706 Lanzhou street so that other luminescent materials manufacturers eclipsed. Lanzhou streetlight manufacturers as technology advances, luminous efficiency, process maturity, large-scale production costs, declining power LED, LED products will gradually replace traditional lighting, Shaanxi Jing Cheng URL: www.sxjczm.com Lanzhou street lighting manufacturers to become the new darling of the field. LED streetlight standards generally are: 1. Solar modules are generally 15% conversion rate, (monocrystalline silicon solar modules) 2. road illumination uniformity (uniformity of road surfaceilluminance) average illuminance 0.48, 0.42 higher than the national standard traditional lights. Spot ratio of 1: 2, 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. 3. Market street lens material for improved optical materials, transmittance ≥93 .%, temperature -38- + 90 degrees Lanzhou street road illumination uniformity lens manufacturers three street (uniformity of road surfaceilluminance) average illuminance 0.48, 0.42 higher than the national standard traditional street spot ratio 1: 2, in line with the road illumination (. Actual 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 4 advantages 1, LED streetlights own characteristics - light, one-way, no light diffusion, guarantee lighting efficiency; Lanzhou street factory 2, LED lights have a unique optical design, the LED street light shines area lighting needed to further improve the efficiency of light in order to save energy; 3 , LED light source efficiency reached 100lm / W, Lanzhou street manufacturers, but there is still much room for development, theoretical value of 250lm / W. The luminous efficiency of the high-pressure sodium lamp is only increased with the increase in power, therefore, the overall light efficient LED lights stronger than high pressure sodium lamp; 4, LED street light color is much higher than the high pressure sodium lamp, 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, light intensity LED lights can reduce the average more than 20% than the high pressure sodium lamp, street light manufacturers Lanzhou (see British sense lighting standards); 5, LED street light is small, light-year decline less than 3%, still use 10 years reach road use illumination requirements, and high-pressure sodium lights big decline, about a year has fallen by more than 30%, so, LED lights in the use of power can be lower than the design of high-pressure sodium lamp; 6, LED street lights with automatic control energy-saving devices, Lanzhou street manufacturers can achieve at different times to meet the lighting requirements of the situation may reduce the maximum power, save energy; 7, LED is a low-voltage devices, drive single LED voltage is safe voltage, single LED products are 1 watt of power, so it is a high-voltage power supply safer than the use of power, especially for public places (eg: street lighting, industrial lighting, automotive lighting, commercial lighting, etc.); 8, each unit LED small pieces only a small volume, it can be prepared into various shapes of the devices, and for the environment variable 9, long life: more than 50,000 hours can be used to provide quality assurance for 10 years, high luminous efficiency: Using ≥100LM more chips, Lanzhou manufacturers with respect to street traditional high pressure sodium lamp energy-saving more than 75% 11. Easy installation: without 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 controlled at about 45 degrees, and the use of passive cooling. 13, reliable: Lanzhou street circuit power supply manufacturers all use 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, thus ensuring no aperture light color uniform.
