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.

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 can form a

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

Image
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 as to realize the uniformity of illumination.

Rule of thumb: what are the installation instructions of DALI LED high bay light?

Image
DALI LED high bay light , also known as LED warehouse light, mainly used in factory workshop, warehouse, exhibition hall, etc., have gradually entered homes, because it is using the latest LED lighting energy saving technology, high reflectivity, high power, high utilization rate of light source. But good lamps and lanterns need specification installation, to highlight its advantages, below for everyone to explain the DALI LED high bay light installation: 1，Define DALI LED high bay light installation height according to the lighting environment, because the environment will change the reflection efficiency of lamps and lanterns. Usually the height of DALI LED high bay light  should be above 5 meters, thread is not close to the lamp shell. If installation height is less than 3 meters, protective measures must be taken to prevent a vehicle to touch. 2，TEK DALI LED high bay light protection class is IP65, choose waterproof transformer, chip packaging place with high temperature resi
