How to measure what is really in line with the lighting quality lighting products

At present, although the LED lighting products have not been widely used in the civil market, but the market is a dazzling LED lighting. However, due to the lack of awareness of LED lighting products, for ordinary consumers, how to determine what kind of LED lamps are in line with the quality of lighting products is still relatively difficult. In the recently held the first China photovoltaic LED Lighting Application Forum, deputy director of the national electric light source monitoring center, Shanghai lighting society.

In order to pursue the high efficiency and long service life, we introduce a generation of production equipment, update generation technology, so we are not to review whether we put the light output of LED products for effective allocation and utilization.

Yu Anqi: only that lm/w is a leaning branch phenomenon Yu Anqi said: "first of all there are several concepts, from an international perspective, lm/w should be called for the light source light efficiency for lamps is not replaceable light source: LED lamp, lm/w lamp efficiency should be called.

Although the same unit, but the two are essentially different, because the light is also responsible for the distribution of light, balance and other issues, so the two are different. But only about lm/w is clearly not enough complete, because if the light radiation lamp to don't need to go, the efficiency is reduced; and if the light to discomfort glare, but not simply the pursuit of lumen meaning.

"He thinks, only that lm/w is an obvious leaning branch phenomenon, not professionals, not on the grade of the pursuit of large international companies. The questions link, with the participants proposed to Yu Anqi without lighting lighting quality products in accordance with the preliminary judgment method, Yu Anqi pointed out: "people-oriented is necessary premise, products not tested out well, is manufacturing out of. He also stressed that it is very important that the product must be considered in the design and manufacture of the last application.

He said that even if the product is very good, if used in the wrong place, lighting design is not the same, can not play a very good lighting effect. Only fully meet the requirements, reflecting the people-oriented efficient lighting, rational lighting is the lighting we need.

Xiao Hongqing: Professor Xiao Hongqing efficient allocation using LED products the light output of national Taiwan University of science and technology said on this issue: "we are optimistic that lm/w, emphasize the LED industry for high luminous efficiency, we will not get lost.

In order to pursue the high efficiency and long service life, we introduce a generation of production equipment, update generation technology, so we are not to review whether we put the light output of LED products for effective allocation and utilization.

"He said, at present all the lighting design, lighting lamps with the biggest problem is very poor, if you can put LED lighting output through method of lamp design makes it the most effective allocation efficiency, such as a large area of the store, the classroom, in fact can reduce 1/3 of the amount of lamps. Reduce the number of lamps, energy efficiency is higher, the recovery rate will be faster for investors. He went on to say that the LED industry should not be as embarrassed as we are now.

We have been using high efficiency products, but not to put its energy use, this is the waste of lighting.

He stressed that the future in addition to light effect and lm/w, should go to discuss with the relevant part, the real effective luminous flux of the light output curve, both coupled with energy power of LED make more effective use of.

He concluded that LED is one of the options available for all of the available light sources, so do not over emphasize LED's energy saving and edge.

It is necessary for us to establish the overall assessment of the lighting design case effectively, to different designers of the case that is consistent with human requirements and meet the purpose of energy saving for total evaluation, thus promoting the development of industrial technology and lighting design.
