| Summary: | 碩士 === 清雲科技大學 === 電子工程所 === 101 === In recent years, the rise of the plant factory has promoted the agricultural development in Taiwan. Besides, the illuminant light source of the plant has been gradually replaced by an artificial light source. Because LED is with the advantages such as a small size and low power consumption over the traditional light source, it has been widely used as the artificial light source of the plant factory in the United State of American, Japan, Taiwan, and other countries.
In fact, it has been successfully demonstrated that LED provides the necessary light of the growth of the plants, e.g., butterfly orchids, oriental lilies, lettuces, cabbages, strawberries, etc. In the past few decades, there has been attracted much attention on the light source of the plant factory. Among the articles, the researchers almost focused on the effect of light source on the plant growth in wavelength and light intensity.
In the thesis, a new method based on optical design is used to improve the lighting way of the plant factory by way of the software named as Advanced System Analysis Program (ASAP). In this research, the parallel light is used as the light source by combining the mining color light, which is formed by using white, red, and blue LEDs, and Fresnel Lens. However, the improved light source is with the merits of power saving compared to the traditional light source. In addition, the light intensity and uniformity can be analyzed by ASAP. Of course, the optimization of the optical model can be also obtained by the improved method. And its feasibility is demonstrated.
