U.S. LED lamp efficiencies above 140lm/W

According to the statistics of the US Department of Energy in 2006, lighting accounted for 11.6% of the US residential power consumption and 24.8% of the power consumption of commercial buildings. At present, the US LED lighting has reached a standard that can compete with traditional lighting in terms of efficiency, but it is popularized. The biggest problem is that the price is too high, and OLED lighting is not yet in mass production.

Based on the results of the seminar in San Diego in February 2005, the US Department of Energy has set a multi-year development plan to increase solid-state lighting performance and reduce its sales price by 2020. The plan clearly states that by 2020, The average luminous efficiency target of cold white LED lamps is 219lm/W, the target price of OEM is US$1 per 1,000 lumens, the luminous efficiency target of OLED lamps is 127lm/W, and the OEM price target is US$6 or per square meter per 1,000 lumens. 80 dollars.

DIGITIMESResearch stated that because the ultimate goal of solid-state lighting development is to replace traditional lighting and become a product commonly used in everyday life, in addition to the above-mentioned technological development goals, the Solid State Lighting Development Planning Council has also established market-oriented solid-state lighting by 2020. Milestones for development, 2020 target for the general level of commercial LED lamps (luminaire) luminous efficiency of 140lm / W or more, the price is less than 100 US dollars (this is to consider the United States price level, and consider lighting design and other factors).

In addition to setting solid-state lighting development goals, the US Department of Energy also provides subsidies for research and development, manufacturing, and promotion of solid-state lighting products in the market. Although the amount of investment in R&D-to-manufacturing is still fairly even, LED products The proportion of subsidies for manufacturing technology development has increased. This shows that the United States has begun to pay attention to LED manufacturing, and it hopes to achieve the goal of reducing costs by improving production technology.
