Right now, nearly 80% LED projects are used in public works. Applying LED technique in civilian projects still need the support of government. After ten years development, LED lighting lamp industry met with its first bottleneck. LED manufacturers thus desired to be involved in more civilian projects. Since LED lamps are normally more expansive than traditional lights, it is hard to be accepted by ordinary families. Due to the low demand of residential LED lighting products and also the low profit of low power LED lamps, manufacturers have no interest in this area. “LED is a more sophisticated lighting technology, consuming less energy, more environment friendly. Government should expand it to people.” Said Fangwei Huang, chairman of Shanghai Lighting Association. Marketing manager of ChangLight Qiang Liu also expressed his opinion “In past five years, we put most of our energy and money in high power LED area. We tried hard to win biddings of public projects, since only in this way we can earn money. Relatively, we are weak in residential LED area. We thought this part is unworthy of attention as the low profit. Now we knew that we were totally wrong. We did not spend enough energy and money in this area. We are lack of technique, which is rather crucial. Besides, we have not established a complete set of distribution channels. Now we have to face up the fierce competitions from overseas ravels, we are vulnerable. ” Within ten years development, LED lighting technique cannot be wide spread as traditional energy-saving lamps in residential lighting area. Government can promote this new technology to people though civilian works. That is the reason why LED merchants called for the support of government.
Bottleneck in technology and equipment. In the field of LED technology and epitaxy equipments, there is obvious bottleneck in domestic LED lighting lamp industry. Independent innovations and patents are concentrated on LED packaging area. In other crucial LED technology fields, like white LED, cooling design for high power LED applications, degeneration problem of fluorescent powder, were monopolized by LED giants from America, Europe and Japan.
Lack of an indentified price standard. Domestic LED manufacturers are generally small sized, resources separated. Most high power LED chips still rely on imports. Lacking of independent LED chip patents increases the cost of small sized LED manufacturers. Thus, it is very hard for them to work out an identified price list for their products.
