| Summary: | 碩士 === 國立成功大學 === 系統及船舶機電工程學系碩博士班 === 101 === The thesis present a novel full wavelength modulation LED (FWM-LED) light engine to improve traditional photobioreactors(PBRs) of single wavelength.
The FWM-LED light engine consists of RGBW LED light sources, coupling lens, and optical fibers. The coupling lens is designed using symmetrical luminous intensity distribution curves, LIDC Mapping, which computing light distribution curve and light energy mapping. This LIDC mapping method can simplify our design into correspondent with the LIDC angles of light sources and target. It is for fiber coupling lens, which is increasing the efficiency of coupling between entrance of fiber and RGBW light sources. In general, temperature could affect alga’s growth either, so providing air condition system to helping heat-dissipating is needed. Therefore, this study design and fabricate the FWM-LED light engine in outdoors then light would pass throughout the coupling lens. The bendable fiber could guide the light into the PBRs providing luminance.
Experimentally observed the biomass of case using FWM-LED light engine are 166% higher than the case only providing white light. Therefore, the FWM-LED light engine can provide spectrums near to the ideal for microalgae to enhance the biomass increasing remarkably in a unit period cultivation.
