Osaka, Feb 9, 2011 – (JCN Newswire) – Sharp Corporation has developed and will introduce high-output, high-color-rendering(1) 25W-class LED lighting devices that boast an industry’s highest luminous efficacy(2) of 91 lm/W for light sources such as store spotlights.
As long-lasting, energy-efficient LED lighting rapidly becomes mainstream, the expectation towards light sources such as product-display spotlights in stores to be using high-output, high-color-rendering LED lighting devices is increasing.
These 25W-class devices(3) have achieved incredibly low energy consumption through the adoption of LED chips and phosphor, which both have excellent high-temperature properties. They provide a high 2370-lm luminous flux and the industry’s highest luminous efficacy of 91 lm/W. In addition, it achieved a high color rendering index (Ra)(4) of 83 by faithfully reproducing the colors of objects. Furthermore, the LED emitting area has been made circular to make designing lighting instruments easy.
Sharp will also introduce a 15W-class lineup to meet a wide range of customer needs.
Main Features
1. Industry-leading luminous efficacy of 91 lm/W achieved within the 25W-class
2. Faithfully reproduces natural colors, with its high color rendering index (Ra) of 83
(1) Color rendering describes how colors are perceived depending on differences in the illuminating light source. The closer to natural light, the higher the color rendering capability.
(2) The brightness per watt. As of February 9, 2011, for LED lighting devices with an input power of 25W, a color temperature of 3000K (GW5DMC30M04), and a color rendering index (Ra) 83 (based on Sharp survey).
(3) GW5DMC30M04
(4) A numerical value expressing the level of color distortion compared to a reference light source. The closer the value to 100, the lower the color distortion.
