LED Street Light An Important Part Of Urban Lighting

Road lighting is an important part of urban lighting, the traditional street lamps often used, high-pressure sodium lamp 360 degrees light, light loss caused by the shortcomings of a huge waste of energy. At present, the global environment is deteriorating, countries are developing clean energy. With the rapid growth of the national economy, China's energy supply and demand has become increasingly prominent, there is a serious shortage of electricity supply situation, energy conservation is an urgent need to solve the problem. Therefore, the development of new and efficient, energy saving, long life, high color rendering index, environmental protection, LED lights on urban lighting energy conservation is of great significance.

Road lighting and people's production and life are closely related, with the accelerated process of urbanization in China, LED lights to directional light, low power consumption, drive characteristics, fast response, high seismic capacity, long life, green and other advantages gradually Into the people's vision, to become the world's most alternative to the advantages of traditional light source of a new generation of energy-saving light source, therefore, LED lights will become the best choice for road lighting energy-saving transformation.

Although there are many LED street lamp manufacturers, but because of the application of LED lights is not a long time, consumers know little about LED lights technology, which also allows many consumers do not know how to buy LED lights, in order to make consumers better Choose their own LED lights, the following is for everyone to analyze a few points.

Power supply Power is also an important factor in measuring LED lights is good or bad, only the use of high efficiency, high precision power supply to ensure that LED lights high energy, long life. LED lights in a large number of applications, PFC is also an important indicator, highlight the lighting LED lights in the PFC level, often become an important factor in the approval of the project.

2. heat dissipation. LED lights on the life of the biggest factor is the temperature, the lower the temperature, highlight the longer the life of LED lights, light fade smaller. LED street lamp cooling is a university asked, its importance and technical difficulty as much as light distribution.

3. Light distribution. LED lights are lighting to the road, unlike spotlights. Spotlights require relatively concentrated light, which is what we usually say "flashlight effect." The LED lights are required to irradiate a large area, uniformity is good. Broadly speaking, the road is a rectangular, according to the characteristics of the road, it requires the road longitudinal (road direction) irradiation area, and the road

4. Waterproof and dustproof. LED lights mostly work outdoors, often by the wind and rain, so waterproof and dustproof is very important. Once the dust into the lamp inside, it will lead to LED lights reduce the luminous efficiency, brightness decreased. If you enter the water, it will lead to LED lights scrapped, so the protection of LED lights should be above IP65.
