Sharp announced nine new LEDs with high color rendering

Jan 3, 2010 Sharp has developed a series of new High Color Rendering LED lighting devices in two package styles. The SMD (surface mount device) chip LEDs are based on a proprietary double molded structure adopted for use in the LED backlights of AQUOS LCD TVs, and feature improved light extraction efficiency to deliver a luminous flux of 38 lumens, the top level in the industry in the 0.5-Watt input power class (GM2BB50BM0C). Zenigata LED devices are now even more compact with approximately half (56%) the surface area of previous models, and provide easy “drop-in” integration into lighting fixtures and equipment.

1.  High color rendering that faithfully reproduces colors—SMD chip LEDs: color rendering index (Ra) of 85; Zenigata LED devices: color rendering index (Ra) of 87. These high color rendering index values are achieved by a combination of a blue LED die covered with a proprietary mixture of green and red phosphors. This structure improves the color distribution of green and red colors, which tend to be more subdued, and ensures beautiful reproduction of natural colors such as the color of flowers and fruits, and skin colors.
2.  The surface mount devices offer improved light extraction efficiency in a double molded structure package design. The SMD chip LEDs adopt Sharp’s own double molded package structure, which is also used in the LED backlights of AQUOS LCD TVs. This design reduces reflected light and improves light extraction efficiency. The 5000K-color temperature model delivers a luminous flux of 38 lumens, the top level in the industry for devices in the 0.5-Watt input power class (GM2BB50BM0C).
3.  Zenigata LED devices feature a package size approximately half that of previous models Optimizing the mounting substrate design enabled the surface area of the package to be shrunk by approximately half compared to previous models (56% of the previous surface area). Integrating these units into lighting fixtures such as bulb-type lamps or downlights is easy and straightforward. In addition, improving the reflectivity of light from the mounting substrate provides a luminous flux of 410 lumens (a 17% improvement compared to previous models) at an input power of 6.7 watts, making it possible to reduce power consumption to approximately one-sixth*7 of a conventional 40-W incandescent lamp of the similar brightness.
