Sponsored by the Taiwan Optoelectronic Technology, “Development of high power white LED packaging technology trends seminar-cum-variety of lighting applications,” in the 9 / 15 held, including the Taiwan Industrial Technology Research Institute, Everlight, lighting giant Osram brand lecturers have attended. According to the Taiwan Industrial Technology Research Institute IEK data show that in 2010 the global LED replacement light source (LED-based bulbs) value (market size) of about $ 1.08 billion, estimated in 2011 up to $ 2.2 billion, 100% annual growth rate of the point of view , 2014, will challenge the $ 10 billion more scale.
For the LED light source may be replaced by the growing popularity of Osram Opto Semiconductors Engineer Li? That, LED lighting to be universal, the cost must be the most important conditions. When the LED lighting ready to enter everyone’s life, there is no way to continue for high prices. LED die size, the decision part of the cost, the greater is basically Wafer LED die can produce more, the LED will be relatively low cost. But every cross a level, the yield on the factory so adjustments may be higher than the semiconductor is also difficult because the emphasis on LED brightness, wavelength uniformity, must be very stable, was successful from the 4? Converted to 6? Process.
Standards are also important factors. At present the region for LED lighting products, components, modules, systems with different standards, but overall, LED lighting standards for speed of development, or behind the pace of industrial development.
Others such as light quality, reliability, but also affect the popularity of LED lighting, a key condition. For example, in terms of quality, LED light source must be sub-bin (LED specifications in accordance to distinguish between different classification), manufacturing side to find a way to do a narrow bin, but in the application side is to find a way to get Bin was wide (to reconcile the light color).
In addition, LED lighting manufacturers experience, is also very important. For example, the LED does not heat, as well as traditional LED light source luminous flux is not as high, they have to rely on vendors to be addressed. Finally, manufacturers must also provide support for LED related applications, such as chips, packaging, etc., in order to promote the use of LED light source.
According to the survey, about 20% of global energy is used for lighting, visible lighting applications the high proportion of total global energy consumption. Analysts believe that if all the global lighting to LED lighting, the overall energy savings will be of great help.
The development of LED, many people think LED lights will be unlimited, but the Li? Stressed that, in fact, limit the efficiency of the cold white light of about 230 lumens / watt, warm white light efficiency limit of about 160 lumens / watt. If dimming through wisdom, we can achieve a good light effects.
CRI CRI value of the performance, development of LED lighting is also one of the key. The so-called CRI, in short, refers to the degree of natural light close, the sun is CRI100 Ethernet basis, CRI higher the value, showing that in the light closer to natural color. The CRI value depends on the different color LED chip and phosphor configuration. Now the market for outdoor lighting requirements of CRI CRI of 70, interior lighting requirements of 82 CRI, shops, museum lighting requirements up to 95 CRI, costs and how to strike a balance between the quality of light is an important issue.
