Why we need use LED high bay light replace matal halide lamp?

In the past years, Lighting using scandium sodium metal halide lamp, the lamps and lanterns has high luminous efficiency, good color rendering performance, long service life etc., is a kind of new light source color close to the sun's energy saving, widely used in sports stadiums and exhibition centers, shopping malls, industrial buildings, streets, square, station, wharf and other places indoor lighting.It has high photosynthetic efficiency (65 ~ 140 lm/w), long life (5000 ~ 20000 h), good color rendering (Ra65 ~ 95) compact structure, stable performance, etc.It has both the advantages of fluorescent lamp, high pressure mercury lamp, high pressure sodium lamp, overcomes the defect of the lamp, metal halide lamp brings together the main advantages of gas discharge light source.Especially high photosynthetic efficiency, long life, light color three advantages.
So the development of metal halide lamp soon, use more and more widely. However in the market with other gas discharge lamp, metal halide lamp with mercury in the padding in the lamp, mercury is toxic substances, making light of mercury injection, careless handling, can cause to the production environment pollution and damage to workers' health, arc tube exhaust, there are traces of mercury vapor discharge, if not handled properly, will be directly discharged into the atmosphere, when using the lamp broken, all can cause pollution to the environment.

Now people use led high bay light replace metal hailde lamp , it is famous in the world with environmental protection , energy saving. The light source of led high bay light use solid cold light source , Without thermal radiation, to eyes and skin without any damage.Do not contain lead, mercury and other pollution elements, realize the true sense of the green,People don’t afraid body hurt . In front of the same brightness of dike, than 700 w high pressure sodium lamp 500 w LED high bay light power saving 60%,its life more than 50000 hours.

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
