General lighting the largest
General lighting including indoor lighting and outdoor lighting two categories. These two types of applications require lamp with high luminance efficiency, long life, environmental protection and other features, the main difference is that interior illumination of the lighting effects and quality (including color rendering, color consistency, the light source and the outgoing degree of uniformity, eye comfort, etc.) have higher requirements, and its consumer-oriented groups to more price-sensitive lighting. On the other hand, the luminous efficiency of blue chip advantage needs to be improved and the limited white China LED packaging technology, the current semiconductor lighting mostly cold white light of high color temperature, plus the consistency of color products compared with traditional lighting is not quite as were intended to make semiconductor lighting outdoor lighting in the current large-scale applications, and in the indoor lighting is just to start. Therefore, the limited cost and quality of lighting, semiconductor lighting will be the first large-scale applications in outdoor lighting, then as the technology continues to evolve gradually into the interior lighting.
A typical application of outdoor lighting is a street lamp, street lighting is an important part of the city, its electricity consumption accounts for much of the lighting. The traditional high pressure sodium lamps with high luminous efficiency of high pressure sodium color index is very low, making the irradiated object color distortion is very obvious; high pressure sodium color of color has improved, but the luminous efficiency, lifetime has the loss; limited by the short-lived, requiring expensive regular maintenance work at height. High pressure sodium lamp with the general performance of poor light, that when the uniformity of lighting is not good enough, and in order to meet the lighting requirements on the uniformity of the general high pressure sodium street light poles are used under the illumination than the demand for many of the rated power, thus resulting in energy waste, therefore, the development of new highly efficient, energy saving, long life, good color rendering index, environment-friendly energy-saving lamps lighting the city of great significance. Outdoor lighting huge market demand, and promote power type China LED street lamps lighting the skill level progresses, costs have been declining, new products are emerging.
Indoor lighting products are the most commonly used incandescent and fluorescent lamps. Inefficient incandescent light, only a dozen lumens / watt, while fluorescent lamps contain mercury and other harmful substances, is not conducive to environmental protection. Therefore, the interior lighting of the high demand for environmentally friendly lighting products more strongly. Although white LED device features such as light-emitting efficiency and environmental protection has been more than incandescent and fluorescent, but its composition and quality of lighting the lamp has not formed quickly the advantages of traditional lighting, interior lighting applications in only just begun. However, indoor lighting the huge market demand, will drive the applications for the interior lighting package and system-level application of technology's rapid development.
