本研究利用LED為光源提出一個新設計的二次光學模組，此模組可使用在可見光通訊和照明上。利用非球面透鏡搭配不同高度和角度的反射杯進行封裝，讓LED的光線透過反射杯反射後與非球面透鏡折射後射出，使光線有高亮度和窄角光束之特性，此特性可大量降低在光通訊時光源的損失，有效的提高LED光源的使用率。並且，使用TracePro光學模擬軟體作此元件的優化設計，並依照優化設計後之參數製作元件。根據實驗的量測結果，此二次光學模組具有窄角的光源，不僅可以提高在此可視角範圍內的照射區域之亮度，並且能夠大量降低通訊時光源的損失進而有效的提高LED光源對傳輸元件的光耦合效率。且此二次光學模組可以達到批量製造以大量降低生產成本，以及兼具高必vLED可見光通訊的光源與照明裝置之功能。

The design creates proposes a new second optical component, which can be used in visible light communication and illumination. We use aspherical-lens with different highness and degree of the reflective cup to produce and package. When LED light travels the reflective cup to reflect and the aspherical-lens to refract, the LED light will be refracted to achieve a high-brightness and narrow-angle. This feature can greatly reduce the loss of optical communication light and effectively improve the utilization of LED light. Also, we use simulation software TracePro for this optimal design, and production of component in accordance with the optimum design parameters. By measuring the second optical module with a narrow angle of the light source can significantly reduce the loss of light in the visible light communication and effective to improve the optical coupling efficiency of the LED light source of transmission components, and improve the viewing angle in this range the brightness of the irradiated area and 0.2 meters transmission distance. The second optical module can achieve high-volume manufacturing to a large number of lower production costs, as well as both high-power LED light source of visible light communication and lighting device.
