在電子產品充斥生活的時代，投影裝置包括教育、商務、家用等各式機種在技術發展上已十分純熟。對消費者來說，除了高畫質的投影品質，其體積大小也是選購投影裝置時的考量重點之一。
In the era when electronic products are full of life, projection devices, including education, business, and home, are very skilled in technological development. For consumers, in addition to high-quality projection quality, its size is also one of the considerations when purchasing a projection device.
傳統投影裝置例如是包括光源裝置、光管(Light Pipe)、透鏡模組、成像元件及鏡頭等。投影裝置中，光源裝置係用以提供光線並使光線聚焦於光管之一端。光管接受聚焦後之光線並將光線均勻化。光管射出之光線匯聚至透鏡模組後，透鏡模組將光線投射至折鏡。經由折鏡反射之後，光線投射至成像元件。成像元件係接受光線並產生影像，鏡頭接受此些影像並將影像投射至屏幕。其中，光源裝置所佔的空間對於投影裝置之體積亦具有舉足輕重的影響。
Conventional projection devices include, for example, a light source device, a light pipe, a lens module, an imaging element, a lens, and the like. In a projection device, a light source device is used to provide light and focus the light on one end of the light pipe. The light pipe receives the focused light and homogenizes the light. After the light emitted by the light pipe is concentrated to the lens module, the lens module projects the light onto the folding mirror. After being reflected by the folding mirror, the light is projected onto the imaging element. The imaging element receives light and produces an image that the lens accepts and projects the image onto the screen. Among them, the space occupied by the light source device also has a significant influence on the volume of the projection device.
