LEDs entering general lighting need to cross the technology and cost two hurdles
LED (Light Emitting Diode) is a light source that is energy efficient, environmentally friendly, long lasting and versatile. Professional consulting organizations predict that the global high-brightness LED market will reach $9 billion by 2011, with an average compound annual growth rate of 16.7%. With the rapid increase in LED luminous efficiency, the LED application market has moved toward general lighting. However, LEDs are also facing bottlenecks such as high cost and high performance uncertainty. In the current global tens of billions of dollars of lighting opportunities, the high price of LED is still the primary factor restricting its development.
High cost cannot be fully commercialized
Since the first commercial LED was introduced in the 1960s, LED has been used in the lighting industry for more than 40 years. The upper, middle and lower reaches of the industry have formed a relatively complete industrial chain. LEDs are being used in more and more In the industry, especially in the field of indoor lighting, it is recognized as an important development aspect of LED future.
In the field of indoor lighting, the main application is still traditional light sources, generally including incandescent lamps, tungsten halogen lamps, fluorescent lamps, metal halide lamps and the like. This type of light source consumes a large amount of electricity, has a single color and control mode, and has a large heat radiation source, and has been limited in some special places. The LED light source has the advantages of full color control, energy saving and environmental protection, which can create a high-quality light environment that cannot be replaced by other traditional light sources. It can fully meet the market demand of high-grade interior decorative atmosphere lighting, and provides a new design for indoor space lighting design. The idea. In particular, the emergence of high-power LEDs has found a breakthrough in the application of LED lighting in the field of indoor lighting, accelerating the application of LED in the field of indoor lighting.
According to reports, at present, the application of LED in indoor lighting engineering is mainly concentrated in the field of commercial lighting, mainly decorative lighting. At this stage, LEDs can be used in many places instead of traditional light sources, especially the emergence of high-power LEDs, which accelerates the speed of LEDs replacing traditional lighting sources, and makes LEDs more practical for large-area applications in indoor lighting. With the continuous maturity of the entire industry and the vertical development of LED product development, high-power LEDs will have a large range of changes in price and light efficiency. Coupled with the strong guidance of national policies and the active publicity of public opinion, we have reason to believe that In the next ten years, LEDs will fly into the homes of ordinary people like the current fluorescent lamps. However, due to the high production cost of white LED indoor lighting, it is still not fully commercialized in the global market.
Tang Guoqing, secretary-general of the Shanghai Optoelectronics Industry Association and director of the Semiconductor Lighting Professional Committee of the China Lighting Industry Association, stressed in an interview that LED enters indoor general lighting is a major trend of development, but because of its high cost, a large-scale upgrade to replace incandescent Lights and fluorescent light sources will take some time, but in the field of mood lighting (indoor museums, concert halls, high-end hotels, residential lighting, etc.), office or reception lighting, indoor public places (such as indoor parking lots, commercial fields, etc.) It has been gradually promoted. The ultimate realization of semiconductor lighting requires the popularization of indoor lighting, which is the keynote of development. Tang Guoqing said.
Peng Wanhua, secretary general of the Optoelectronic Devices Branch of China Optical Optoelectronics Industry Association, said that the cost of LED lighting products is too high, several times that of ordinary lighting, and some are ten times. The field of LED product application is currently in the stage of development and expansion, and has not yet formed a large-scale market, which needs further development and expansion.
