What aspects to consider LED street lamp ？

Luminous efficiency
LED lighting technology matures, high-power LED light source has been able to meet the general needs of luminous flux. In general, the luminous efficiency of high pressure sodium lamp is 100lm/W, but the color rendering is poor. The use of high power abroad the best LED chip can reach 100lm/W, the domestic LED lighting industry leader TEK LED street lamps can be developed more than 140lm/W. The higher the luminous efficiency, means that the better the energy saving effect, which is one of the most important indicators to choose LED street lamp. However, the LED standard is not clearly defined, so in the purchase of LED street lamps must be carefully confirmed.

Dissipate heat
LED because it is a semiconductor component, the chip temperature is reduced to 30% of the initial luminous flux, it will lose the meaning of lighting, that is, the end of life. In theory, the service life of high power LED street lamp is 3-50000 hours, but the important premise is to have good heat dissipation. For example, the domestic LED lighting industry leader in the production of TEK LED street lamp, the use of modular heat dissipation, good heat dissipation performance, to ensure the long life of lamps and stable reliability.

Three, LED street light manufacturer strengthen
LED street light with the choice of chip and how to strengthen of the cooling . Some businesses in order to reduce costs, the use of hundreds of 0.5W small power LED. However, the small power LED light is very serious, its decline to 80% of the life of only 1000 hours. So, as the need for long-term use of lamps is not allowed by this small power LED, LED street light with large power (power LED chip TEK is currently using 1--2W.)), the light a lot better.

What ways can see LED street lights to replace the high pressure sodium lamp?

Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
