LED lighting development focus shifted to quality and cost

LED chip because many manufacturers have to produce very high energy efficiency, thus reducing the quality of white LED lumen cost will be the priority among priorities for the development of led. As the LED market continues to expand, the output value in 2010 increased nearly doubled, semiconductor lighting bulbs more and more on the shelves of household goods. It seems to be telling people that the solid state lighting era has arrived. Over the past few years, the efficiency of white LED chips, packaging, lighting has been significantly improved, but the general lighting is still in a very early stage of development. Most of the assessment that the current LED in the field of general lighting penetration of less than 5%. Although various designers are keen to explore the application of LED lighting technology possible solutions, consumers will be willing to accept the lighting scheme so that they can save money, but LED wants to dominate the lighting market still has many problems to be solved. LED lighting application status is a "when", not "if"". PHILPS Lumileds, Europe, Middle East and Africa Mark van marketing director den Berg said, will now focus on LED lighting and system of quality and cost. Held earlier this month in the UK in 2011 in Coventry at eurOLED Mark van den Berg said: "the chip has a very high efficiency, however, we must provide a lower cost per lumen, in order to accelerate the popularity of LED lighting market. "Van den Berg quoted the U.S. Department of energy (DOE) latest MYPP plans 20 times mentioned the improvement goal, in order to discuss the application of LED packaging cost should be reduced to much. That is, by 2020 the cost of LED package to achieve $1 /1000lm, while LED lamps only $5 /1000lm. As of 2010, the most advanced LED packaging costs fluctuate from $10 to $/1000lm. However, because of the combination of blue and fluorescent powder to achieve the best efficiency, so this figure applies only to designers and consumers are disgusted with the cold white light. U.S. Department of energy estimates that in 2010 the cost of warm white LED package between $20 to $25 /1000lm. Recently reduced to $18 /1000lm. But even so, Mark van den Berg proposed nearly 20 fold improvement goal is achievable. U.S. Department of energy has also set to achieve the medium-term target of $7.50 /1000lm in 2015. LED TV Strategies Unlimited led growth analysts said that despite the 2010 general lighting market gained strong power in high-end applications, but 93% of the market growth is mainly driven by TV backlight. "LED products are widely used in TV backlight sources, and other mature markets, such as automotive lighting, in some key areas and different from general lighting. "Van den Berg said. Large scale production of TV sets or cars, choose a product that meets the requirements of the application LED. Therefore, its LED products will be a single type of product, it is easy to mass production. In other words there is no nuance. Millions of televisions or cars use almost the same equipment. However, in the field of general lighting, different types of application needs, whether it is working lights, residential, office or street lamp, the difference will be very large, making the LED light source in the field can not be a generic product. The specific application environment has a fundamental impact on the application of LED lighting in the commercial field. For example, Italy van den Berg Alpine tunnel in May by LED lighting solutions, because the tunnel lamp has been lit, so even the transformation of the huge cost, return on investment is also very fast. On the contrary, so far, office lighting has proven to be a very difficult market. Part of the reason is that T-5 fluorescent lamp is a very efficient and cheap products. In the retail industry, the demand is also different. With the emphasis on light and color quality, it is becoming more and more important to give the best CRI for each lighting application. At this point, the halogen lamp is the main competitor of the LED lamp, not the fluorescent lamp. Retailers also want to see their products "shine" in the perfect light, and at the same time, LED can do this skeptical. The change of domestic lighting, in the absence of burst stimulation factors, van den Berg that replace the light bulb for $10, you can achieve large-scale application. The typical price is $40. For outdoor lighting, such as street lights, has a wide range of enabling LED lighting. But the van den Berg still believes that the investment return period is too long, we should improve the efficiency and reduce the cost of the investment return period is less than 3 years. Only in this way can we achieve large-scale application. It is clear that the general lighting market is actually composed of many different markets, demand points are not the same. Of course, the cost requirements are consistent. Compared with traditional lighting, LED lighting has more potential. The retail sector opens the way to success in the retail sector is the success of the LED enterprise is the best. The California based chip maker in December 2010 to the Austria sports / fashion chain Intersport provides LED products for the entire store lighting. According to the European marketing director Tom van Puri den Bussche introduced a new lighting technology versatility means that it can more effectively guide shoppers. This is a classic case of "value added". Van den Bussche also said that the five stores are renovated in a similar pattern. So the development of the European Union may be in the short term there will be hundreds of chain stores using LED lighting. Another obvious advantage of LED lighting is that the LED lamp does not emit ultraviolet light
