LED high bay light compared with high-pressure mercury lamp parameter

Traditional warehouse lamp with 250 w and 400 w high pressure sodium lamp and metal halide lamp, and compared the characteristics of the new type of LED lamps and lanterns has more obvious difference, as shown in the table below:

Considering the actual use of high pressure sodium lamp and metal halide light failure and secondary light problem, its actual luminous efficiency is far lower than the 80 lm/W, often cannot achieve the nominal 7.In this for the first time, we developed LED high bay light set about 80 w power, once the illumination effect is in line with expectations, than traditional lamps and lanterns namely energy saving more than 50%.

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 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...
