How to choose high quality of LED high bay light?
How to choose high quality of LED high bay light? This is what people care about, Now , let's take a look.
1, the luminous efficiency
LED lighting technology becoming mature, high power LED light source has can meet the general high bay light luminous flux as needed.The average high pressure sodium lamp light efficiency is 100 lm/W, but the color temperature is poor.The higher luminous efficiency, energy saving effect means the better, which is one of the most important indicator to choose LED high bay light .TEK LED high bay light are more than 130 lm/W, however, LED does not have explicitly stipulated in the standard, so must be carefully confirmed when purchasing LED high bay light.
2, light failure
light failure of LED high bay light is mainly related to choose what kind of chip as well as how to strengthen the heat dissipation.Some businessmen in order to reduce costs, with hundreds of small power LED 0.5 W.However, this kind of small power LED light failure is very serious, its light failure and 80% of life is only 1000 hours.Therefore, as the need for long-term use, lamps and lanterns is absolutely not allowed use of this kind of small power LED, selects the high power LED, the light failure will be much better.
3, heat dissipation
LED is semiconductor components, its wafer is affected by temperature and reduced to 30% of the initial luminous flux, will lose meaning of lighting, also is the life end.Theoretically the life of the high-power LED high bay light is 50000 hours, but the premise is to have a good heat resistance.such as TEK lighting product 180W LED high bay light, Adopt the acicular radiator cooling efficiency than conventional flake radiator is greatly improved, can make the LED junction temperature 15 ℃ lower than the ordinary radiator above, its good heat dissipation performance, ensure the service life of lamps and lanterns for a long time and stable reliability.
