Key Trends in the Development of LED Lighting Technology

Key Trendsinthe Developmentof LED Lighting Technology Developments in LED lighting technology are taking place at a dramatic pace, heavily influencing the LED industry chain as well as final products. LED lighting prices are expected to fall by 30% per year, with luminous efficacy approaching 200 Im/W in next couple of years. PRIE 30% Cree, the largest US-based LED manufacturer, had its 2W LED package products rated as high as 161 Im/W in 2011. CREE TM ØNICHIA It is higher than the maximum luminous efficacy of 133 Im/W for Nichia. German giant Osram achieved luminous efficacy of 146 Im/W. OSRAM OSRAM However, it is Japanese manufacturer Toyoda Gosei that has positioned itself at the top of the market with the launch of a TOYOD A GOSEI 170 Im/W LED. 200 Im/W 170 Im/W 161 Im/W 146 Im/W 133 Im/W Im/W CREE OSRAM ORAM ØNICHIA TOYODA GOSEI There have also been breakthrough developments in terms of capacitors, a key component affecting the lifespan of LED lighting products. Heat dissipation is another area where LED lighting manufacturers continue to make improvements. These various technological improvements should make a major contribution to increasing LED lighting uptake in the future, as they reduce the number of LED chips needed, reduce overall lighting costs, reduce power consumption, and improve LED usage rates.
