          Taiwan LED lighting technology latest developments

          The US Department of Energy (DOE) speculated in the Multi-Year Program Plan in March 2010 that the price of 1,000 lumens of white light source in 2010 will fall to $13, and it is estimated to fall to $6 in 2012. 2 dollars, the price will be comparable to high-intensity gas discharge lamps (HID), even lower than the energy-saving lamps (Compact Fluorescent Lamp). At present, the manufacturing cost of 5W LED bulbs is about 12~14 dollars, and the price is still high. It can be reduced to 7~9 dollars in 2012. It is expected to have a penetration rate of 10%. In 2015, it is estimated to fall below 7 dollars. It is expected that With a 50% penetration rate, it will also be a mature period for LED lighting.

          DOE also estimated that the LED industry's cool white luminous efficiency in 2010 is 134lm/W, but the efficiency of the light, circuit and heat dissipation of the lamps is only 64%, and the LED lamps will only have 86lm/W. Therefore, through the technology to improve the photoelectric thermal efficiency of the lamps and LED luminous efficiency and heat dissipation capacity is the current direction of LED lighting industry in Taiwan.
