Abstract

The luminaires utilizing high power LED are prevailing for general use. In the application, multiple numbers of LED are required to attain the desired brightness. It is important to control the light distribution to combine the luminous flux from each LED. We designed and fabricated the luminaire to control the luminous flux of the LEDs and succeeded to obtain the designed uniform light distribution with small deviation of chromaticity.
