Nyingchi solar street lamps, discussion the development advantages of led lights

As the demand of the modern development, the led street lamp that this kind of product, the more energy saving and emission reduction by the vast number of consumers love, here we make a brief introduction of the led street lamps in the street lamp industry, its competitive advantage is what aspects: 1 green environmental protection: the led does not contain harmful metals hg etc.

with the demand of modern development, led street lamp as product of energy conservation and emissions reduction, more and more get the favour of consumers. Let's briefly introduce led street lamps in the street lamp industry's competitive advantage: 1 green and environmental protection: light-emitting diodes (leds) contains no harmful metallic mercury and other heavy metals, and does not produce pollution, unlike high pressure sodium lamp or metal halide lamp, when the scrap will cause harm to the environment. 2 long service life: led street lamp light attenuation is small, light attenuation is less than 3% within a year, still can satisfy the requirement of road lighting, after 10 years of use and high pressure sodium lamp light attenuation is bigger, fell more than 30% a year or so. Therefore, compared with high pressure sodium lamp, led street lamp of lower power consumption, long service life. 3 high safety factor: LED street lamp is low voltage products, of course, this is a solar LED street lamp, 12 v is enough, still is 220 v mains LED street lamp. Energy saving: at present, the light-emitting diode light source efficiency is 110 - 130 lumens per watt, the theoretical value of 250 lumens per watt, still has great development. However, high pressure sodium lamp luminous efficiency as the only power increases. As a result, the overall luminous efficiency of LED street lamp was stronger than high pressure sodium lamp. Is made of high power led light source and high efficient power supply, after testing the actual lighting effect than the road use of high pressure sodium lamp comprehensive energy saving more than 60%, technological progress is still large, 0 +. With rapid increase the efficiency of the light emitting diode, light emitting diode lamp shows great potential in energy saving. 5 low maintenance cost: according to the current technical level and the test result, high power led light source can be normal use 10 years without replacement, and the traditional high pressure sodium lamp need to be replaced once a year and a half on average, so using led light source can be greatly reduced maintenance costs. 6 color WenKeXuan: light-emitting diodes (leds) can meet the requirements of different occasions on the color temperature, and indoor and outdoor temperature requirements are different. His family had different from commercial lighting lighting. In addition, some stores need to replace the led white light, to make their products more fashionable and delicate, and satisfy the appetite of consumers on the color. The color temperature and high pressure sodium lamp is too low, let a person feel depressed and hypnosis. Yellow light will give a person a kind of hot in summer. 7 no stroboscopic: led street lamp can rapid response, shorten the lighting time, and do not flicker, suitable for eye protection. Good color rendering: led street lamp light color reproducibility is far higher than that of high pressure sodium lamp. Light-emitting diodes, high color rendering index ( 75 ~ 80) , high pressure sodium lamp's color rendering index is only about 23. From the visual and psychological point of view, led street lamp light intensity of more than 20% lower than the average high pressure sodium lamp. In addition, the road looks brighter, feel more comfortable, the driver feel more secure.
