LED street lights to replace the traditional street lamp - open the new era of green lighting

City road lighting light source basically traditional high pressure sodium lamp, fluorescent lamp, etc., among them, high pressure sodium lamp, with its characteristics of high photosynthetic efficiency, spray penetration, used in road lighting is the largest.There are more and more city road lighting using LED lighting technology to replace the traditional lighting technologies, its purpose is to reduce the consumption of electricity.

Combining with the characteristics of road lighting design in our country at present, the LED street lamp technology constantly improving, more and more used in our country's road reconstruction project.In the near future the traditional street lamps will exit the market, and using LED street light, let's look at the deficiency of traditional street lamps and the LED street light.

Using high pressure sodium lamp as road lighting exist the following deficiency :

(1) direct illuminate of lamps and lanterns on the ground, and high intensity of illumination, trunk road in some times also can reach more than 401 lx, but obviously, this belongs to excessive lighting illumination, and are responsible for a large number of energy waste.

(2) the efficiency of high pressure sodium lamp reflector are only about 50-60%, which suggests that, in the lighting by nearly 30-40% of the light irradiation inside the lamps and lanterns, the overall efficiency of 60%,there are serious waste phenomenon.

(3) theory, the life span of the high pressure sodium lamp is 15000 hours, but the influence of the power grid voltage fluctuation and running environment, its service life far cannot reach theory of life, the damage rate of lamps and lanterns is more than 60% a year.

Compared with the traditional high pressure sodium lamp, LED street lamp has the following advantages:

(1) as a kind of semiconductor devices, in theory, the useful lifespan of LED lights up to 50000 hours, compared with 15000 hours of high-pressure sodium lamp is much higher.

(2)LED street light CRI can reach more than 80 , very close to natural light, in this light, the eye of recognition can be effectively, thus ensuring road safety.

(3) in the street lamp open, high pressure sodium lamp needs a preheating process, the light from dark to bright need a certain amount of time, not only caused the waste of electricity, and affect the effective development of intelligent control.LED street lights at the instant of the open can achieve the best lighting, there is no such thing as an start time, therefore can achieve good intelligent energy-saving control.


Above all, compared with using high pressure sodium lamp road lighting, the LED street light to energy conservation and environmental protection.There is no doubt that with the progress of science and technology, energy-efficient light source will be constantly emerging, as a professional manufacturer of LED lamps and lanterns, TEK lighting innovation design, grasps the lighting the use of new technology and new equipment, always put the energy conservation and environmental protection work of the first place, TEK lighting is a good choice for you.
