Right now, Chinese LED lighting Products consumption accounts for almost 12% of the electricity. Lighting consumption almost accounts for 19% in the global content. Energy conservation has become a demand of the global world, many manufacturers hope to find more energy-efficient light, but energy-saving is not the only indicator. “LED is not the only lighting, the lighting also has a good purpose.” “forum held on the afternoon of April 26, 2012, fromFudan University, Professor Chen Yuming said, due to LED develops so fast, a lot of other lighting and advantages are coated. Between the solar powered led lighting, fluorescent lamps, ceramic metal halide, incandescent, oled, and many other light sources, there isn’t exist any difference. The key is where does this light source come from.
There is no doubt that LED should be a very important and promising light source. LED luminous efficiency has been greatly improved, the CREE laboratory level has reached 254lm / W. In addition to the luminous efficiency, the entire system of LED lamps, such as luminaires, intelliegent control, power and other factores may play an important role on the application of solar powered led lighting. Currently, LED light source also has a long way to go.
The present white LED are sparkled by the blue lights and added yellow fluorescent powder, it can extend the product color index more than 90 by the red band. But compared with the sunlight, the white LED spectrum of light in the 480mm range exists little, and in a wider area, which can affect the human biological clock.
But it does not say that LED is not good. We need to address the problem and solve the problem of intermediate spectrum missing. Right now, many munufacturies remedy the spectrum missing by phosphor technology, or by UV LED, the zinc oxide as a media and other ways. “If the LED spectrum have been made up, the promotion of solar powered led lighting is not the price problem.
The price is never a problem. Once LED street light has a real large-scale mass production, a light to spend few dollars will not be a problem. The biggest problem is that you can actually meet the needs of lights. That will be the target problem which dominate the marketing.
