Seoul Semiconductor's New Top View LEDs with High CRI Gain Wide Market Acceptance
2008.07.24.
Seoul Semiconductor's release of High CRI, High Luminous Efficacy and High Reliability Top View LEDs has gained rapid market acceptance. In addition to their high CRI, Seoul Semiconductor's Top View LEDs have a luminous efficacy of 70lm/W and a life expectancy that exceeds 50,000 hrs. These new Top View LEDs enable lighting designers to achieve best-in-class indoor lighting.
Incandescent bulbs and halogen lamps have dominated the interior and display lighting market segments because of their high CRI (100). But because of their low luminous efficacy (10~15lm/W) government authorities worldwide have passed legislation, which will go into effect over the next few years, banning the sale of these products.
With high CRI, superior lumens per watt and long life, Seoul Semiconductor's new top view LEDs are poised to dominate the lighting market segments where high-performance light sources are a must.
Seoul Semiconductor's new Top View LED series: Warm White part (CAWT722-S) has a CRI of 96 and achieves 68 lm/W, while the Pure White (CWT722-S) has a CRI of 92 and produces 70 lm/W.
According to a Seoul Semiconductor official, these new items are said to provide 4 times higher luminous efficacy than previous lighting sources while meeting the stringent requirements of today's lighting designers.
