Seoul semiconductor top view LED three high performance

Seoul semiconductor (Seoul Semiconductor) said that the color index in May last year listed (CRI: Color Rendering Index) close to 100Ra suitable for 0.2W lighting market top view (Top View) LED has been put into application in multiple projects.

Seoul semiconductor said, in addition to the high color rendering index advantage, these 0.2W class top view LED luminous efficiency of 70lm/W, reliability of up to 50 thousand hours. In April this year, held in Germany Light&building exhibition and the Light Fair exhibition held in the United States in May, this product has been a great response from the lighting and decoration design industry application manufacturers.

As is known to all, the color rendering index of 100Ra is currently used as a fluorescent tube or a halogen lamp. However, due to the low efficiency of 10~15lm/W, the world will limit the use of this light source, is expected to be banned after 2010. In order to adapt to market changes in energy efficiency and green environmental protection awareness and increasing awareness of the climax of the lighting industry, many attempts to use high color LED to replace the light source, but it is usually considered that LED high efficiency will reduce the color index, not suitable for lighting.

Therefore, Seoul semiconductor in April this year launched a warm white Warm White (commodity name: CAWT722-S) and pure white Pure White (Name: CWT722-S). Which:

CAWT722-S: color rendering index of 96, that is to achieve the current light source 3~4 times more than 68lm/W. CWT722-S: luminous efficiency of 70lm/W, not only can emit pure white light, but also has a 92 color rendering index, which is higher than the current value of the light source of 30%. Moreover, through the technical research and development of Seoul semiconductor to solve the current color rendering index is higher, it will reduce the reliability of the problem, to ensure the service life of 50000 hours.

Seoul semiconductor is expected, with the recent expansion of the government to accelerate the pace of popularization of LED, these top LED will be due to its excellent high color, high efficiency, high reliability and other features have been used for indoor lighting.
