LED high bay light may be more energy efficient but bring new problems to the environment

LED high bay light have gradually replaced incandescent bulbs because they typically consume less energy and the bulbs themselves can last a considerable amount of time. More efficient lighting means good things to the environment. Now that many modern cities are changing from outdated lighting technologies, the scientists point out that we may have made a big mistake.

In a new study published in the journal science advances, researchers set out to determine the extent of the global deterioration in light pollution. Their findings reveal bad news and even worse news. The bad news is that more and more parts of the world are being illuminated by artificial lights, and the worse news is that LED high bay light is likely to be the culprit.

Using observations from powerful weather satellites, the researchers could determine that the whole earth was brighter than a few years ago, with the rapid growth of "the disappearance of night" in Europe and the United States. But why does this happen?

According to the scientists, several factors are at play, including LED high bay light that are increasingly common, providing more illumination for cities and keeping the current energy budget. Many areas simply add more outdoor LED high bay light, rather than simply lowering the cost of LED high bay light.

Most importantly, as the size of the city expands and the first outdoor LED high bay light infrastructure is installed in previously underdeveloped areas, light pollution increases.

Experts stress that covered  LED high bay light illuminated only by reservation area can solve the problem, or at least significantly reduce the severity of the problem, but to meet this requirement needs the joint efforts of all countries.

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...
