2014 semiconductor lighting applications will face challenges

Introduction: the development of semiconductor lighting in the field of lighting is irresistible, and it is of great significance to China's energy conservation and emission reduction. But at the same time, the future development of semiconductor lighting industry is also facing some challenges.

Recently, the alliance national semiconductor lighting project (CSA) in the middle of the semiconductor lighting industry development forum held in Hubei hosted by Yichang, the forum, vice president, China Construction Science Research Institute of architecture and Environmental Energy Research Institute CSA Application Promotion Committee put forward six major challenges facing the semiconductor lighting applications director Zhao Jianping. After 10 years of development, China's semiconductor lighting has been in the road, commercial lighting, public lighting and other fields to promote and apply, permeability gradually increased.

First, the development of China's semiconductor lighting enterprises need to be strengthened.

Semiconductor lighting products in the development and Reform Commission organized national demonstration project sampling, in addition to the "structure", "creepage distance and clearance", "surge" three indicators qualified rate is 100%, other indicators have different degrees of failure rate, the "mark" a qualified rate was only 4%, was ignored many enterprises.

Secondly, the performance of semiconductor lighting products need to be improved.

According to the three ministries demonstration project tracking and detection of luminous flux rate data show that the request of "testing technology of semiconductor lighting demonstration project (2010)" products 3000 hours luminous maintenance rate is 96%, while in the field in the four quarter (about 3600 hours) the average luminous maintenance rate is only 90%, the lowest is only 78% the product, far lower than the measured value, even single quarter (900 hours) light attenuation reached 25%. , the data were lower than expected.

Thirdly, the lack of product innovation ability.

Many of the products still remain in the imitation of the traditional forms of lighting lamps, such as bulb stage, the form is not the future direction of the development of semiconductor lighting, semiconductor lighting needs according to their own characteristics, to develop more creative products.

Fourth, enterprises need more understanding of lighting applications.

At present, many enterprises in the production of products is not conducive to the designer's selection, or to the enterprise product parameters provided by designer is not complete, the designers do not understand the product, and between products of different enterprises have not been able to form a standard production, the product market is not standard, the product price is not high, have hindered the popularization and application of semiconductor lighting product.

Fifth, many designers do not understand semiconductor lighting products, there are some doubts.

But the semiconductor lighting has low power, small size, can be any combination of light, high concentration; peak intensity; flexible control, fast response, variable power; abundant colors and images can be dynamic full-color control advantages are very suitable for the use of lighting designers. In the future application of the promotion process, enterprises need to strengthen communication with the designer, to play their respective strengths, learn from each other to create more excellent engineering design case.

Finally, the semiconductor lighting field there are still some key problems need to be studied, such as the blue light hazard problems, visual comfort, color evaluation, dimming effect on color temperature and color rendering index etc..
