How to judge the merits and demerits of LED high bay light source?

As an industrial power, China occupies a certain amount of energy consumption in the energy consumption of factories. Therefore, the use of new LED light source for luminous raw materials lighting - LED high bay light, thus can achieve energy conservation and environmental protection effect, becomes the focus of attention. So which factors influence the quality of the lighting source of the LED high bay light, how to judge the light source?
UFO
1,Considering the electrical properties of the semiconductor luminescent diode in the electrical properties of LED high bay light

 The PN junction of LED is a one-way nonlinear conduction characteristic, low voltage drive and electrostatic sensitivity. Unlike the electrical characteristics of traditional light sources, the main measurement parameters include forward driving current, forward pressure drop, reverse leakage current, reverse breakdown voltage and electrostatic sensitivity.


2,The PN junction temperature of power LED is considered in terms of heat dissipation performance

 It is very important to solve the PN junction temperature and shell heat dissipation problem of LED high bay light with high power and luminous efficiency. The thermal properties of LED high bay light are generally used for thermal resistance, shell temperature and temperature.



3,The reliability and life span of LED
In particular, the lighting source of LED high bay lights is more important as LCD backlight source and large screen.We evaluate the lifespan of LED does not mean that used to damage the cycles are available, and it is the LED under the condition of rated power, luminous flux attenuation to the initial value of the specified percentage when the last time.The longer the duration, the longer the LED life.



4,Considering the radiation safety of LED light source for biological or human body

 Due to the LED high bay lamp light source is a narrow beam of light, high brightness light-emitting elements, the radiation may cause damage to the retina, so, the international electrotechnical commission IEC for application of LED light source used for different occasions.

The limit requirement and test method of the effective radiation are provided, which is an important factor to judge the quality of LED high bay light . Among them, the European Union and the United States make mandatory requirements for LED radiation safety testing.

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...
