Led solar street lighting system status and market forecast
Department of Energy (DOE), lighting program manager JimBrodrick made a presentation entitled to the LED industry, led high bay state and Market Forecast ¡°report, the report describes the solid-state lighting (SSL) shortcomings of the technology and limitations of LED technology used in other applications.
Brodrick First Department of Energy, led solar street lighting system, concerned about the SSL and LED lighting technology investment reasons, Brodrick said that if the seven kinds of traditional lighting applications are replaced by LED lighting may be an annual saving of energy of 233 megawatt-hours (TWh) electricity ¨C enough to support the electricity of the nineteen million households.
Brodrick in the center of the report of the United States SSL industry,led solar street lighting system, talked about the LED lighting products, he said: ¡°If you start from a blank sheet of paper design and come up with products that are really good.¡± He also added that good The design must address all aspects of a lamp, including the LED chip, optical, electronic, thermal management and mechanical design.
Brodrick said that the LED used in recessed downlight lighting, outdoor area lighting, the performance of 2¡Á2 feet dark light trough lighting and freezer lighting is perfect, but LED application containing only minor alteration of a light bulb lamps, led solar street lighting system, linear replacement lamps and the performance of the concave circular ceiling lighting is not ideal. But. 4 feet of linear LED lamps has been gradually improved, close to the efficiency of fluorescent lamps, directional LED light output and distribution is still not as good as the fluorescent light to diverge into the entire cylindrical.
Nevertheless, Brodrick said, or LED lamp light output and cost advantages in some applications applications, led solar street lighting system, such as those hard to reach places for longer life of LED lamps. He also said that the LED lamp is a good choice often occurs in the areas of vibration and climate extremes. Another example those containing only a small modification of a light bulb lighting, Brodrick said that the LED used in this technology has been getting better and better, led solar street lighting system, but they are generally smaller than the incandescent light output, light color quality and light distribution.
