OSRAM released 1A input current can be obtained 191lm luminous flux green LED

[BP] the Nikkei news agency reported Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors GmbH) developed the 1A drive time, luminous efficiency of 48lm/W flux is 191lm, wavelength of 527nm, green LED, and Las Vegas in the United States at the "ICNS-7" (September 2007 16 ~ 21 days) show: (speech serial number: D1). Chip size 1mm square. 350mA drive time flux of 100lm, luminous efficiency of 81lm/W, wavelength of 532nm. In addition, the chip size of 460 m * 532nm 255 m, 20mA drive when the luminous efficiency of 107lm, the oscillation wavelength of the product. These two products are higher than the company's original product brightness. Conceived as a light source for LED projectors and other image display devices.

This by improving the "Droop" phenomenon and so improve the brightness. Droop refers to the blue LED, green LED, such as InGaN as the light-emitting layer of the LED to improve the input current density when the luminous efficiency decreased.
