Description
本發明係關於一種色輪及其製造方法,特別是指安裝於於投影機內,用以讓投影機之光源通過並對投影機之光源進行分色之色輪者。 The present invention relates to a color wheel and a method of manufacturing the same, and more particularly to a color wheel mounted in a projector for passing a light source of the projector and coloring the light source of the projector.
現今一般之投影機大多係採用微鏡片反射技術(Digital Micromirror Device,DMD),並採用色輪(Color Wheel)來完成對色彩之分離和處理,色輪主要係由紅、綠、藍、及另外加入的其他顏色之彩色濾光片所組合而成。在應用DMD投影系統之投影機中,投影機之光源所發出的白光藉由透鏡聚焦於色輪上,且色輪係受投影機之高速馬達驅使而轉動,藉此將光源所發出之白光進行分色,並將具有顏色之光束發射到DMD表面上,DMD再將光束反射後經過透鏡投射出投影機。 Most of today's projectors use the Digital Micromirror Device (DMD) and use Color Wheel to separate and process the color. The color wheel is mainly red, green, blue, and A combination of color filters of other colors added. In a projector applying a DMD projection system, white light emitted by a light source of the projector is focused on a color wheel by a lens, and the color wheel is driven by a high speed motor of the projector to rotate, thereby performing white light emitted by the light source. The color separation is performed, and a color beam is emitted onto the surface of the DMD, and the DMD reflects the beam and projects the projector through the lens.
值得注意的是,習知之投影機之色輪係採用矽膠等高分子膠體與螢光粉混合後而製成螢光膠,其中,高分子膠體之熱穩定性差,隨著激發光源的功率增加,會造成螢光膠的劣化,例如矽膠僅可耐約150℃之溫度,及約2000流明之亮度,當溫度高於150℃時,矽膠將會老化及黃化,造成色 輪結構損壞,因此無法應用於高溫度或高流明數的光學系統。 It is worth noting that the color wheel of the conventional projector is made of a polymer colloid such as silicone and a phosphor powder, and is made into a fluorescent glue. Among them, the thermal stability of the polymer colloid is poor, and as the power of the excitation light source increases, It will cause deterioration of the fluorescent glue. For example, the silicone rubber can only withstand a temperature of about 150 ° C and a brightness of about 2000 lumens. When the temperature is higher than 150 ° C, the silicone will age and yellow, resulting in color. The wheel structure is damaged and therefore cannot be applied to optical systems with high temperatures or high lumens.
有鑑於此,本發明人潛心構思並更深入研究,終於發明出一種玻璃螢光體色輪及其製造方法。 In view of this, the inventors have conceived and further studied, and finally invented a glass phosphor color wheel and a manufacturing method thereof.
