U.S. LED industry status and market forecast

San Diego, California in the United States held "2011LEDs conference," U.S. Department of Energy (DOE) program manager JimBrodrick lighting as the first spokesman issued a report entitled "The United States state of the LED industry and market forecasts," the report, JimBrodrick described in the report solid-state lighting (SSL) technology and limit the success of wholesale cheap LED light used in other applications of technical shortcomings.

    Energy concerns Brodrick first introduced SSL and LED lighting technology investments for the reasons cited in the Department of Energy report released earlier this year, Brodrick said that if the seven kinds of traditional lighting LED lighting applications all from the alternative, may be an annual energy savings 233 megawatt hours (TWh) of electricity - enough to support nineteen million households electricity.

    Brodrick in the middle of the report describes the SSL industry of the United States, spoke of LED lighting products, he introduced: "If you start from a blank sheet design and come up with products that really good." He added that good design must address all aspects of a lamp, including LED chips, optics, electronics, thermal management and mechanical design.

    Brodrick said, LED lighting used recessed downlights, outdoor area lighting, 2x2 feet in the dark and frozen lighting lamp trough lighting performance are perfect, but the LED bulbs used in only a small modification with lamps, linear replacement lamps and concave circular ceiling lighting performance is not so good. But. The four feet linear LED lamp has been gradually improved, close to the efficiency of fluorescent lamps, but the directional LED light output and distribution of fluorescent lamp as the light is still not as good as divergent as the cylindrical type.

    Nevertheless, Brodrick said, LED lamp because the light output and cost advantages in some applications or applications, such as those hard-to place for longer life on the LED lamp. He also said, LED lamp on the vibration often occurs in the region and climate extremes is still a good choice. Another example is that only a small light bulb with a modified lighting, Brodrick said that while LED technology has been applied to this getting better, but they are generally inferior to incandescent light output, light color quality and light distribution.

    Brodrick also recently introduced the Department of Energy test: Energy purchased the 33 LED light products in eight major U.S. retail stores for testing, the results show that the majority failed to meet basic performance parameters, consumers are more satisfied with incandescent or halogen the lighting effects.

    In color quality, Brodrick said,cheap LED bulbs manufacturers have made significant improvements, more stringent classification of lighting manufacturers is helpful. DOE will continue its multi-year program plan for SSL to increase lumen output and performance targets. In performance terms, Brodrick said, we are seeking to cool white 2020 258 lm / W this goal
