LED general lighting commercialization process and solution selection analysis
Under the trend of energy conservation and environmental protection, LED lighting has become the target of many regulatory agencies. For example, the 1.1 version of the US Department of Energy's "Energy Star" program has entered into force in February 2009. The China National Institute of Standardization is also expected to be prepared in 2010. Released the Chinese version of LED lighting energy efficiency standards. It is estimated that by 2012, the market size of LED drivers and related discrete devices will increase from approximately US$688 million in 2008 to US$1,308 million, with a compound annual growth rate of 17.4%. LED general lighting is still in its infancy Although the LED prospects are now being heated up, the relevant data shows that in the general lighting market, which is dominated by light bulbs and fluorescent tubes, recessed lights, street lights and parking lights, and work lights (table lamps, cabinet lighting). The proportion of LED lighting applications is still less than 1%. Taking outdoor LED street lighting as an example, most of them are only used as government demonstration projects. The real commercial popularity seems to take time. Zheng Zongqian, senior application manager of OnSemi Hong Kong and China, believes that the reason why LED street lamps can be used as demonstration projects depends on their high luminous efficiency, low reflection loss of lamps, no need for high pressure, no mercury, and higher safety. Secondly, compared with ordinary lighting, LED lamps are easier to add digital or analog dimming functions, which is convenient for remote control, and can provide ultra-high brightness and color rendering in special cases such as foggy and rainy days. In addition, LED street lights are significantly superior to high-pressure sodium lamps in terms of laying costs, power consumption costs, and life. At the same time, however, the relatively high cost, low reliability of the power supply, and short range, which are not conducive to working at higher heights, are still important factors hindering the rapid development of LED street lights. On the other hand, if the government can introduce LED road lighting standards in time, it will be a very powerful means to popularize LED street lights. Li Yingyou, senior manager of Fairchild's PLM lighting technology marketing, said that LED street lighting is part of the government's energy efficiency program. The upgrade includes not only replacement of light bulbs, but also the use of long-life rectifiers. “The first step in the upgrade is to install LED streetlights in the newly developed area and then gradually replace the existing old streetlights. It is expected that most of today's streetlights will be replaced by LED lighting in the next five years.†Zhang Jing, sales manager of ADI Central China, believes that compared with outdoor lighting , LED indoor lighting is in its infancy, and the current cost performance is not high. This is because the lumen cost is too high, and on the other hand, LED indoor lighting products. There are too few types, lighting designers have no choice but to set an obstacle to the promotion of indoor lighting products. His suggestion is that the development and promotion of LED indoor lighting products should focus on product family, integration, intelligence and humanization, improve luminous efficiency and luminous flux utilization, and minimize overall integrated lighting costs.
