Energy trend, LED lighting opportunities and challenges coexist

From the first incandescent lamp lit up the world, to the LED lights set off a new wave of green, human lighting technology has gone through a long history of development. Today, when a variety of lighting needs can be well met, the future of the most important development direction of lighting is also more clear - that is "energy saving". Therefore, there is a "Ten City" strategic deployment, only the Olympic Games, "Water Cube" LED landscape lighting system, only a large number of World Expo LED lighting decisions. So what exactly is the scene of LED lighting? July 31st held in Shenzhen, China LED technology and Cooperation Forum opened the tip of the iceberg.

There is a certain gap between ordinary lighting costs

The topic of LED is now very hot, the meeting of several business executives are reminded to keep a clear head. Gong Weibin, chairman of Shenzhen Ruifeng photoelectron Limited by Share Ltd on the reminder, on the LED lighting industry, we must be objective and calm look at the problem, because ultimately people pay. Living in the United States for many years, high tech online CEO Zhang Xiaofei also said that the United States to deal with LED lighting projects more rational. After all, LED lighting also has a short board - the most significant of which is the cost problem.

LED lighting costs are still high, about 10 times more expensive than ordinary lighting. Experts attending the meeting said that the cost will certainly decline with the progress of technology and the development of the market. On the one hand, with the materials, equipment depreciation, preliminary research and development / maintenance cost along with the improvement of the production capacity gradually decreased, on the other hand, the epitaxial growth process, structure design, chip manufacturing and processing technology improvement and application package after the maturation of LED chip is bound to make the yield increase, thereby reducing the cost.

The question is, to what extent? From the material, technology, maintenance and other aspects, LED lights in order to reduce the cost of close to ordinary lighting, will be a very long process. Looking to the future, if the light efficiency of 200 lumens / watt, the cost can be reduced to the general lighting of the 5 times, the market is not a faster development?

In addition, for municipal lighting and so on a large system lighting project, the cost of the LED light is on the one hand, the system can effectively reduce the cost is also a problem. Dr. CREE technical director Shao Jiaping also acknowledged that the design of LED lighting system has a certain complexity, all aspects of the understanding of the LED technology, the outdoor lighting system, familiar with the circuit design and so on the understanding of knowledge and experience will affect the quality of design and the final effect. This puts forward higher requirements for the project implementation, if the future gives birth to a more professional team to complete this task, it is bound to cause the cost of spending.

Standards and patents

Currently in the small and medium power lighting market, with the growing range of LED lighting applications, industry tipping point is also coming. As one of the "ten city lights" covering the city of Shenzhen as an example, the upcoming Universiade, Metro two more than and 30 subway stations, street reconstruction project etc. will be large-scale use of LED lighting, decorative lighting in addition, driven by the consumer market with safe and convenient characteristics will increasingly be applied. No rules do not Cheng Fangyuan, detonated the market needs standards.

Dr. Shao Jiaping said that at present many national institutions such as CALI (China Association of Lighting Industry China Lighting Electric Appliance Association and CSA (China Solid - State Lighting Association) of the Ministry of industry standardization Chinese semiconductor lighting industry and research alliances, and other units are in the LED industry especially the formulation of related lighting standards. How long is the real standard? Ruifeng chairman Gong Weibin believes that the development of LED lighting devices too fast, the development of the standard has a certain degree of difficulty". In addition to the standard formulation also take into account the problem with international standards. Dr. Shao suggested that the United States Department of energy, the International Institute of illumination and other institutions IES work, learn from each other, that is, to adapt to national conditions, but also with the international synchronization. And Gong Weibin believes that the local enterprises to join hands with Taiwan, Hongkong, together with the development of standards applicable to greater China region more desirable.
