Most of general lighting will be the next big cake

General lighting including indoor lighting and outdoor lighting two kinds big. Applications require the two lamps with high luminous efficiency, long life, environmental protection features, the main difference between indoor lighting light source for illumination and quality (color, color consistency, exitance and uniformity of light source and the human comfort, etc.) have higher requirements, and geared to the needs of consumers more sensitive to prices of lamps and lanterns. Blue chips, on the other hand, the advantage of the luminous efficiency of further improve and is limited by the white light LED packaging technology, the semiconductor lighting lamps and lanterns is mostly high color temperature of white light, and color consistency compared with the traditional lighting is not satisfactory, the semiconductor lighting now has a large-scale application in outdoor lighting lamps and lanterns, in the indoor illumination is only just beginning. Is limited by cost and lighting quality, therefore, semiconductor lighting will take the lead in large-scale application in outdoor lighting, with the continuous development of technology after gradually enter indoor lighting area.

Outdoor lighting is a typical application of street lamp, street lamp is lighting is an important part of the city, its power consumption accounted for a large part of the whole lighting electricity. Traditional street lamp adopts high voltage sodium lamp, luminous efficiency of high pressure sodium lamp high color rendering index is low, illuminate objects color distortion is very obvious; High color rendering of high pressure sodium lamp color rendering have improved, but the luminescence efficiency, life has been lost; Is limited by its short life, so you need often expensive high-altitude maintenance operations. Generally high pressure sodium lamp light distribution performance is poor, also is the uniformity of road lighting is not good enough, and in order to meet the requirements of road lighting uniformity of high pressure sodium lamp lights are commonly use than the light pole illumination demand many rated power, resulting in energy waste, therefore, to develop new type of high efficiency, energy saving, long life, good color rendering index, environment friendly street lamps for urban lighting energy saving is of great significance. Outdoor lighting in the field of huge market demand, driving the power type LED street light, etc. The technology progress of lamps and lanterns, falling costs, new products are constantly emerging.

Interior lighting is the most commonly used product incandescent and fluorescent lamps. Incandescent lamp luminous efficiency is extremely low, only ten several lumens per watt, and fluorescent lights containing mercury and other harmful substances, is not conducive to environmental protection. Therefore, indoor lighting more strong demand for efficient environmental protection lighting products. Although the white LED the luminous efficiency and environmental protection device has features such as more than the incandescent lamp and fluorescent lamp, but made up of the lamps and lanterns of lighting effect and the quality is not quickly to form the advantages of traditional lighting light source, its application in indoor illumination is only just beginning. Indoor lighting, however, the huge market demand, will promote the indoor lighting application oriented encapsulation, and system level application technology of rapid development.
