LED heat will be short-lived"

LED light quality expert clinic results

LED has many advantages, but the applications in general lighting, energy saving and long life can not do, this is the day before the Guangdong for the first time on the LED lamp "quality experts clinic results.

LED heat is not good will be short-lived"

"We have been to environmental protection, energy saving and long hanging in the mouth, but the practical application, there is still a big problem of longevity. "Professor of national quality supervision and inspection center of lighting engineering, senior auditor Yu Anqi said, in the backlight lighting landscape lighting, LED, has been basically can do long, but in the field of general lighting, LED also cannot achieve high efficiency and long service life.

LED most afraid of high temperature, when the heat is not good, it will cause low luminous efficiency, shorten the service life. Yu Anqi said, with the LED lamp experimental road lighting, tunnel lighting the national electric light source quality inspection center in more than and 70 batches, in the light of 1500 hours, about 70% of the products (luminous maintenance rate as an indicator of life) are below 80%. "The product is expensive, only the longer service life, better maintenance coefficient, otherwise there is no meaning. Yu Anqi said.

According to reports, the street life of the highest level of domestic LED is only about 20 thousand hours, less than 50 thousand hour in some promotional materials.

Guangdong xuelaite photoelectric technology Polytron Technologies Inc director Luo Nengyun believes that the next 35 years, for indoor lighting LED light will gradually increase, but in the high power LED lamp for indoor lighting technology is not mature.

Indoor LED lamp "color" is not good

Yu Anqi said, the color of the LED lamp is not good is one of the obstacle to the indoor lighting field. The use of a bad color, the color will be distorted. "In accordance with the standards, indoor lighting color to achieve 80 incandescent lamp and fluorescent lamp can reach LED, but the lamp has not reached, or color to light effect, and does not pass, you can't do both, this is the future direction. Yu Anqi said.
