LED lighting in the future of home lighting is inevitable
LED interior lighting, interior lighting can be adjusted in light of morning, noon, night changes in time, so that the indoor environment close to the light of the moon, stars, sun and natural light. It has now begun to enter in semiconductor lighting home lighting, holiday decorations, from the simplest lights, lamps, desktop system, chandeliers, lamps and a gallery of garden, especially the combination of solar cells has become a highlight of the conditions of modern life, play a role beautification quality of life.
Semiconductor lighting speed of development is basically the luminous efficiency every 18 months increased by 50% and cost reduced by 1 times. Semiconductor Lighting Program of the roadmap to know U.S. in 2007, and gradually the white LED lighting market in general. 2010, part of the white LED replace fluorescent lighting, home lighting, including access to the main market. Lighting applications in the semiconductor market in China has already overtaken United States, believe that 2010 will be lighting in the home occupy a large market share.
lighting conditions inside the light source are: to ensure that work, study and living environment to achieve a comfortable light illumination and good levels of quality, objective and color brightness of the display of objects, access to eye human to see the real effect of the external features. In a high light output, bright enough, you should also be close to the color temperature natural light and high color rendering index. Interior lighting semiconductor major problems first need to increase the luminous efficiency; Second Instead, color temperature, the current excited blue phosphor white LED yellow color temperature synthesis of relatively cold, third is the index color-representation, the ideal ratio of solar color spectrum Gaps; Fourth, life, real life is affected by many factors, from the theory of 10 million hours of life is still relatively far away, 5 is the power, power, and can meet the needs of interior lighting. LED semiconductor lighting interior lighting is to enter the general lighting market, the most important milestone, the technical problems faced by the most prominent, which has continue to develop the following aspects. First, to improve the quality of epitaxial silicon material, to improve the internal quantum efficiency and luminous efficiency, increase the life of the LED, and second, the improvement of LED packaging technology, to improve the luminous efficiency, and address high-power LED thermal problems, again, the large-scale production, lower production cost, LED; Finally, the development of new technologies to improve color temperature and color of the LED coefficient.
From the perspective of technology development at home and abroad, LED interior lighting in all homes is inevitable. Reasonable and effective government organizations, along with our capabilities and enterprise-related research foundation, we are fully confident of achieving this goal. Home Lighting LED lighting tools, if widely adopted, this market will be enormous. The next three to five years is an important period development, semiconductor lighting and general lighting will come. With the upstream chip R & D of new technologies mature and suppliers MOCVD capacity epitaxial furnace continues to expand, greatly reduce unit production costs of LED, thus ending the largest LED lighting barriers overall cost.
