learn to distinguish the quality of the LED corn light is very importance

Although LED corn light by office lighting consumers welcome more and more,  LED corn light market appeared a lot of poor quality of the lamps and lanterns at present,.If we do not pay attention to this problem, it is very easy to buy inferior products, so learn to distinguish the quality of the LED corn light is very importance.

1, identify the quality of LED corn light is unqualified or not, firstly should look at the appearance, ensure that the appearance of lamps and lanterns , There is no crack ,loose. When install and disassemble, cannot become loose or slanting phenomenon.Surface of lamps and lanterns use materials should be fire retardant.

2, the temperature. LED corn lights in the use of average surface temperature is relatively low, but if the cooling condition is poor, so in the case of high temperature is easy to appear the phenomenon of hot, light failure will also change, which affects the service life of lamps and lanterns.Inferior LED corn light In the process of use, can appear flashing phenomenon.

3, listen to the sound: electromagnetic compatibility of qualified LED corn lights is tested, so you can put the radio on nearby when in use of lamps and lanterns, the lower the noise of the radio to receive, clarify measured electromagnetic compatibility is better, on the contrary, the lamp is poor quality.

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...
