Abstract
We report generation of pure-white color by mixing red, green, blue (RGB) lights from LEDs through a novel 3??3 fiber optics color synthesizer (FOCS), which is made of hard plastic cladding fiber (HPCF). The three output ports provided an equal power for the synthesized white color with almost identical CIE color coordinates. The FOCS rendered tunable white color temperature and optical properties of the outputs were experimentally investigated in terms of uniformity in power, photometric luminance, and color coordinate. We further packaged the device and applied to small form factor back light unit (BLU) to show feasibility in illumination uniformity enhancement.
