The 12 v simple solar street light

Light, generally refers to the street for more than 15 meters high. Since the height of it so high, so it USES the light source power must be very great. General light, a light source power is 200 w and 400 w, 15 meters high lamp often use one or two light sources, but those

light, generally refers to more than 15 meters high street lamp. Because of its high altitude, so it's power must have a high light source. In general, the power of light, a light source for 200 or 400 watts, 15 meters high lamp usually use one or two light source, but 25 or 30 metres high lamp need more light, so light, the power consumption is very big. A few years ago, light, often using the traditional high pressure sodium lamp as a lamp holder, but now the light emitting diode technology has been mature, high lamp use more led light source. So do you know why the use of led light source in high lamp more beneficial? 1. High luminous efficiency, lighting effect is good. Led light source of luminous efficiency is a good light source on the market at present, the luminous efficiency has reached around twice the traditional sodium lamp. At night the whole lighting effect is very good. In addition, the led light source is very popular on the market at present energy-saving light source, it and save electricity and solar power are very compatible. Second, the energy consumption under the condition of the same brightness, light emitting diode light source power consumption is a third of the traditional sodium lamp. If use the traditional sodium lamp solar street lamps, they will need a higher configuration, this will raise the price of solar street light. LED light source, low energy consumption, however, has more advantages in the practical application of solar energy street light. Third, long service life. The service life of led light source of up to 50000 hours, suitable for all kinds of bad environment and working temperature, high stability. With solar street light led light source can almost 5 - without maintenance Six years, without the traditional high pressure sodium lamp needs frequent maintenance trouble. LED light source advantage is the key to energy conservation and environmental protection. Light is a kind of high power lighting appliances. Replace after with LED light source, a year can save a lot of electricity. The idea of how to promote energy conservation and environmental protection in China, make the light and LED light source has more advantages.
