With high-brightness LEDs (HB-LED) to improve light output, energy efficiency and cost, combined with small, low-voltage work and environmental protection, LED lighting is setting off a lighting revolution. In the trend of energy saving and environmental protection, LED lighting has naturally become the target of many regulatory agencies.
After three releases of the ENERGY STAR standard, the US Department of Energy (DOE) finally released a final confirmed version of the ENERGY STAR standard for LED light source fixtures, which is required to take effect on August 31, 2010.
The release of the ENERGY STAR standard clearly shows that the US Department of Energy is eager to follow the release of LED lighting standards, so that the LED lighting products of related industries can follow the rules, and the LED lighting industry will receive moderate protection. CFL coverage. The promotion of the early CFL, due to the uneven quality of the products, led to many negative experience, and became the trigger for the difficulty of product promotion.
Carefully review the new version of ENERGY STAR's solid-state lighting standards. One of the key points of the standard is to require a power factor (PF) for a variety of home lighting products, up to a minimum of 0.7. These products include portable desk lamps, cabinet lighting and outdoor corridors. Lights, etc. These LED lighting fixtures typically range in power from 1 to 12 watts and are low power applications, and the most suitable power topology for such low power applications is the isolated flyback topology. However, most of the current standard designs for designing these power supplies typically have a power factor of only between 0.5 and 0.6.
The ENERGY STAR standard provides new quantitative standards for solid-state lighting such as LEDs. This is a good thing for the LED lighting industry. It represents the energy-saving regulations that the LED industry can follow. In addition to the previously published safety regulations, LED lighting products have already Can slowly grow in the market of the public and private sectors.
