Abstract
The spread of LED lighting is expected as one of the effective means of the prevention of global warming. It can contribute not only to reduce CO_2 emission to replace incandescent lamps with white LED sources, but also effective means on economy. By this report, the characteristic comparison of the luminaires is performed and technical issues for the LED lighting are examined. In addition, the latest LED luminaire is introduced. The performance enhancement of the white LED continues, and the application to the general lighting is expected.
