LED Street Lighting The Point Of Choose And Buy
Sep 30, 2017

LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance.

Road lighting is an important part of urban lighting. Traditional street lamps are often adopted, and the high pressure sodium lamp has a 360-degree glow. The disadvantages of large loss of light cause great waste of energy. At present, the global environment is deteriorating and countries are developing clean energy. With the rapid growth of the national economy, China's energy supply and demand contradiction is becoming more and more prominent, the power supply is beginning to have a serious shortage, and energy saving is an urgent problem to be solved. Therefore, it is of great importance to develop new high efficiency, energy saving, long life, high color index and green LED street lighting.

Road lighting is closely related to people production and living, with the speeding up of urbanization in our country, LED street lamp with directional light, low power consumption, good drive performance, fast response, high seismic ability, long service life, green environmental protection advantages of gradually into people's horizons, to become the world's most advantages instead of traditional light source of a new generation of energy-saving light source, therefore, LED lights will be the best choice of the road lighting energy saving reconstruction.

The point of choose and buy

Luminous efficiency

The technology is becoming more and more mature, and the high power LED light source can meet the needs of ordinary street lamps. General high pressure sodium lamp light efficiency is 100 lm/W, commonly used high power LED is 50 to 60 lm/W, with abroad the best LED chip can reach 80 lm/W, the higher luminous efficiency, energy saving effect means the better, which is to choose one of the most important indicator of LED street lamp. However, LED standards do not have specific provisions for this, so they must be carefully identified when purchasing LED street lamps.

droop

And some businesses, in order to reduce costs, use a few hundred 0.5w small power leds. However, this small power of LED light is very serious, its light and fall to 80% of life is only 1000 hours. Therefore, as a street lamp that needs to be used for a long time, it is absolutely not allowed to use this kind of small power LED, with the high power LED (generally referred to as over 30W), its light failure is much better.

Weight problems

Because of high technology content and complex components, LED street lamps will be much heavier than normal high pressure sodium lamps, so the requirements for supporting materials are higher. However, some LED lights manufacturer has as much as possible to reduce the weight of the LED lamp holder, from the original single lamp holder about 30 kilograms, dropped more than 10 kilograms, weight loss and the trend of decline further.

Heat dissipation

LED for semiconductor components, the wafer is affected by temperature and reduced to 30% of the initial luminous flux, will lose the meaning of lighting, or put an end to the life, the life of the high power LED street light in theory 3-50000 hours, but the premise is have good heat resistance. It is worth mentioning that domestic manufacturers have adopted the world's leading needle-like cooling technology.
