Color scanner using White Led Light Source wins the Illuminating Engineering Institute of Japan's Lighting Technology Award 2011
TOKYO, September 21, 2011 - A color scanner using a white light-emitting diode (LED) light source developed by Fuji Xerox Co., Ltd. and Fuji Xerox Advanced Technology Co., Ltd., its affiliate company, received the Lighting Technology Award 2011 from the Illuminating Engineering Institute of Japan. The award ceremony was held on September 15.
The companies incorporate the white LEDs as the light source for the scanner units in their digital color multifunction devices. Having overcome LEDs’ non-uniform brightness and color variance, Fuji Xerox’s LED scanner has achieved the brightness 1.5 times greater than that of a xenon lamp at approximately one-third power consumption. The technology was highly rated for offering enhanced energy efficiency, convenience and productivity compared to former models.
White LED light source technology
In recent years, digital multifunction devices have been required to scan documents faster to enhance office work productivity. Higher scanning speed needs higher illuminance at the light source, however, while less power consumption is also required.
To overcome this challenge, Fuji Xerox and Fuji Xerox Advanced Technology decided to adopt white LEDs, which require less power than xenon lamps, as the light source. Although LEDs were considered to be difficult to use for this purpose because of their non-uniform brightness and color variance, the companies succeeded in achieving 1.5 times the brightness of a xenon lamp at one-third the power consumption while maintaining consistent scan image quality, by developing an optical component that achieves a uniform light dispersion, as well as an image processing technology that automatically performs digital color correction.
Lighting Technology AwardThe Lighting Technology Award commends excellent achievements expected to greatly contribute to the society including; development of light sources, fixtures and control systems with exceptional functions, performances and energy-saving performance, outstanding improvements to current methods, and unique ingenuity of designs or manufacturing methods

Introduction of the LED Scanners to Products
Fuji Xerox first introduced this award-winning color scanner to the eight models four models of ApeosPort-IV series multifunction device as well as four models of DocuCentre-IV series released in August 2009. Since then, the company has been incorporating the scanner into flagship models including a full-color digital multifunction device, ApeosPort-IV C2260 released in December 2009, and monochrome digital multifunction devices, DocuCentre-IV 3060/2060 released in July 2011.
