  • Review of LED Lighting and Technology

    Although realization of blue LED was said to be difficult within the 20th century, the study on gallium nitride by Professor Akasaki (present specially appointed professor at Meijo University/special professor at Nagoya University) laid the base of today’s blue LED and white LED, which was realized using blue LED technology. LED is used for backlights of mobile phones, notebook PCs and TVs. Recently, in particular, for the purpose of energy and electric saving, demand of LED for lighting has been increasingly expanding. In this lecture, the current conditions, strong points and other things of white LED for lighting obtained through activities of the Japan LED Association as well as the development history, technology evolution, future development, etc. of blue LED, the basis of white LED, will be introduced.

  • LED Past Perspective for Future Development and Growth

    The tremendous improvement in white LEDs, particularly over the last few years, is spurring significant growth in LED lighting. Clearly the improvements in efficiency, light output, reliability, stability, and color quality are impressive. Ten years ago white LED was no more efficient than incandescent lamps. Today, LED solutions can be more efficient that some fluorescent systems. In combination with global interest in energy saving, such LED improvement is now enabling LEDs to quickly replace other conventional lamps. As LED solutions gain share in the illumination markets, the performance requirements are becoming greater and more is being asked of the underlying LED technology. In this talk, we will review LED development so far and look ahead to what LED technology should be in the future.
