How to choose a good LED corn lamp?

Current LED corn light fair ground are far quoted price of every trade, and they all said that their products have more than a lot of good, how to judge the quality of LED corn light as a layman?The LED corn lamp is based on several parameters:

1,Light decay. The better LED corn lamp declines by 30 per cent before 25,000 hours.The main factors that determine the light failure are the quality of the light source, the difference of the cooling structure.

Foreign original factory packaging of high power light source, such as CREE failure is better than  domestic packaging, as amateur can't see the light source, simple way of judging the main is the price , foreign light source of the original light source is higher than domestic packaging price .

So if you want to buy a good quality LED corn lamp ,you have to provide the manufacturer information about light source.

2, light effect. Namely each watt of lumens, the unit LM/W, it is to reflect the energy-saving performance of the lamps and lanterns, better lamps and lanterns, its light effect is higher. As leds light effect improve, TEK LED corn light is likely to produce 130LM/W this year.

3, light source. LED corn lamp using large power LED as light source, the price is higher;

4,Power supply. A good driver power supply can guarantee the life of the whole lamp, LED has a theoretical life of 50,000 hours, but general power supply life is less than 50,000 hours.

In order to guarantee the life of whole lamp, the driving power supply is also a key link.On the other hand, leds have to be constant current drivers, and low cost constant pressure drives shorten the life of the LED.

How to choose a high quality LED corn light? That is consumers care about this problem, according to above several factors to choose can avoid buy inferior LED corn light, choose the right LED corn light.

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...
