LED illumination with fluorescent lamps cost gap has been less than 5 times. 10 times the cost per watt is still commonly used in fluorescent lamps and other efficient light sources, but because of the LED light source features a one-way, detailed product design and high efficiency driver circuit, which cost five times less illumination. The illumination corresponds to the number of lumens in a specific area, the user really care indicators. Costs and cost per watt illumination of the significance of the differences, LED lights will be more fluorescent lamps, which are about 50% of the energy-saving effect.
At present the cold white LED lighting lamps in the field of non-residents have with the economy. Estimates that take into account the effect of energy-saving LED lights use about 10,000 hours to recover costs, and product life is already significantly exceed this level. In order to consider the impact of time value, we use a discount rate of 20%, still found in current prices, 10 hours / day, 250 days / year use the occasion has been a positive economic value, which will include most of the non-resident lighting applications.
There is still a huge decline in the cost of space, including improved light efficiency, economies of scale and industrial return to reasonable profits. Chip prices have started, the end of 2011 the cost of LED light illumination will fall 30-40% lower than the current, we believe the price will start after the warm white light, or 4-6 hours / days and other applications, which include most of the non-resident lighting applications, while the 2012 home lighting, such as LED light lamps will also be large-scale application.
