At the 2011leds conference in San Diego, Calif., the US Department of Energy (DOE) lighting program director Jim Brodrick gave the report titled US LED Industry Status and Market Forecast, and Jim Brodrick introduced solid-state lighting (SSL) in the report. Successful technology and technical shortcomings that limit the use of LEDs in other applications.
Brodrick first introduced the Department of Energy's focus on SSL and investment in LED lighting technology, citing the Department of Energy report released earlier this year, Brodrick said that if all seven traditional lighting applications are replaced by LED lighting, energy savings may be achieved each year. 233 megawatt-hours (TWh) of electricity - enough to support the electricity used by 19 million homes.
In the middle of the report, Brodrick introduced the US SSL industry. When talking about LED lighting products, he introduced: If you start designing and taking out products from a blank sheet of paper, it is really good. He added that good design must address all aspects of a luminaire, including LED chips, optics, electronics, thermal management, and mechanical design.
According to Brodrick, LEDs are perfect for embedded downlighting, outdoor area lighting, 2x2 foot dark lighting and freezing lighting, but LEDs are used in small retrofit lamps with one light bulb, straight replacement lamps and The performance of the concave circular ceiling lighting is not so ideal. but. The linear 4-foot LED tube has been gradually improved, approaching the efficiency of fluorescent lamps, but the light output and distribution of directional LEDs are still not as divergent as the fluorescent lamps. Despite this, Brodrick said that the advantages of LED light bulbs in terms of light output and cost will be applied to longer-life LED tubes in applications such as those that are difficult to reach. He also said that LED tubes are still a good choice for areas with frequent vibrations and extreme weather. For example, those small retrofit lamps that contain only one light bulb, Brodrick said that although the technology used for LEDs has become better and better, they generally do not match the light output, light quality and light distribution of incandescent lamps.
Brodrick also introduced the Department of Energy's recent test: The Department of Energy purchased 33 LED light products for testing at eight major retail stores in the United States, and the results showed that most failed to meet basic performance parameters, and consumers were more satisfied with incandescent lamps or halogens. The lighting effect of the lamp.
In terms of color quality, Brodrick said that LED manufacturers have made significant improvements, and stricter grading is of great benefit to luminaire manufacturers. The Department of Energy will continue its SSL multi-year work program plan to increase lumen output and performance goals. In terms of performance, Brodrick said that we are striving to achieve the goal of 258 lumens per watt of cool white light by 2020.
