RGB LED混光機構應用於口腔照明之研究
Study of RGB LED Color Mixing Mechanism for Oral Illumination
摘要
本論文主要在研究口腔照明檢測之手電筒燈具，透過手電筒內部的反射鏡架構設計來完成RGB LED色彩混色之燈具，從過去的研究中發現色彩混色通常要使用導光管、擴散片及透鏡等多個光學元件完成色彩混色，因此希望能利用光學設計自行研發出反射式之混光燈具拉長色彩混色的距離，並藉由Solidworks建立模型及ASAP模擬光線追跡情形。在各燈具前方放置一工作面，利用工作面來進行分析，分析的項目包括照度、照度均勻度及色彩混光效果。根據模擬的結果可以了解反射面設計的方法可以使照度更加均勻且結構簡單化，使其能達到節省成本的目的，而混光燈具可以透過調變LED的發光強度比例，改變其混色以應用在不同的照明上，因此在這種均勻且架構簡單的色彩混色方法可以做為色彩口腔照明燈具的架構設計方式。

This paper studies the detection of oral illumination flashlight lighting, through a flashlight inside the mirror architecture designed to perform the RGB LED color mixing lighting, from past studies typically use color mixing light pipe diffusion sheet and a plurality of optical components such as lenses to complete the color mixing, so we hopes to use the self-developed optical design of stretched the distance mixed light reflective color mixing lighting. By Solidworks modeling and ASAP ray tracing simulation scenarios, lighting placed in front of each one face, face to use for analysis ,project analysis, including illumination, illumination uniformity, color mixed effects. According to the simulation results can be designed to understand the method of the reflecting surface can be simplified and a more uniform illumination, it can achieve the purpose of saving costs, the mixed light lighting can change its color mixing through modulation of the LED luminous intensity in different lighting, so in the future will be for oral illumination medically helpful.
