The fraudulent means about buying LED chip

LED chip, also called light bead, critical components of  LED high bay light,  luminous flux and electricity are determined by it. Because the LED chip is encapsulated inside, so we can’t directly observe, but as long as you don't covet little advantages, you can buy high quality LED high bay light light.Here said the LED chip common fraudulent means.


Use small chip , deceive consumers that is big chip
LED chip is a very important part of the LED high bay lighting, with the development of technology, the chip size changing. the greater ,the resistance to voltage, electric current ability is stronger, but the cost will be higher.

Some vendors use small chip packages, specification identify larger forward current, due to good engineers often only use about 75% of the forward current to ensure the service life of lamp bead, reduce droop, so on the surface the brightness of the light bead is the same as the other suppliers or even higher than that of other suppliers, but in fact is greatly reduce service life of LED lamp bead.


Use unco chips to counterfeit famous chip
people lack knowledge.Some of the LED high bay light factory from the above consideration save cost, using domestic chip which technology is not enough stable . And pretend to be CREE , Osram , so the easiest to make people spend a high price to buy low quality products caused a direct economic loss, as the same time,  LED high bay light products have serious quality hidden trouble.


Everyone must polish eyes when choosing LED high bay light, you must believe that cheap goods is not good. So must choose high quality manufacturers .

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...
