No.7（2012）13.Application of rapid prototyping to a LED luminaire for the showcase

Takashi Hasegawa, Seiji Koganei, Hideko Sakai

  The present study aims to spread and expand the high-resolution modeling Rapid Prototyping (RP) business by developing a showcase for the display using RP. In the study, LED circuit design for low power consumption was investigated, and optimization of electronic components and circuit configuration was discussed. Moreover, the light diffusion plate, a part of the LED panels which was designed using RP, achieved inconspicuous glare. Although a showcase of the module type development was attempted, color unevenness of the light source occurred in the vertical plane. The prototype will be shown in an exhibition as a luminaire for base panels.
