1235878 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種色輪，特別是一應用於投影系統的 色輪。 【先前技術】 由於大顯示面積、小型化以及輕量化系統的多重需求 下’影像投影系統成為目前光電產業中最熱門的分項之 0 現今流行的投影系統共分為三大類型，分別是液晶投 影顯示器（Liquid Crystal Display Projector，LCD)、單晶石夕 液晶顯示器（Liquid Crystal on Silicon，LCoS)以及數位光源 處理器（Digital Light Processing，DLP)。其中，LCoS 與 DLP具有系統簡單化的優點，以下將以DLP為例說明。 DLP投影機係採用數位控制，同時係利用反射光原理 進行作動。首先，光源經由集光柱（Light Integration Rod ) 集光，再穿過色輪中之彩色濾光片分光後，投射至數位微 鏡晶片（Digital Micro_mirror Device，DMD)上。在此技 術中，係藉由數位微鏡晶片來取代傳統液晶投影機中，負 責呈現影像的液晶面版。由於數位微鏡晶片上具有許多微 小的可動鏡片，以驅動電極來控制可動鏡片傾斜角度 與偏轉時間，再藉由切換光的反射方向由鏡頭投射呈 像。 其中，色輪係由彩色濾光片以黏著膠黏合於馬達 1235878 上所組成，再藉由馬達的帶動俾使彩色濾光片沿著中 心旋轉。然而，由於系統内的光源溫度常高達950°C到 1000°C，進而導致整體投影系統的操作溫度亦居高不下。 由於黏著膠於高溫下容易脆化，是以光源所產生的高溫不 僅降低色輪的使用壽命，同時，其他元件的可靠度亦受影 響。 為解決此一問題，現行的做法係將風扇設置於光源、 色源以及數位微鏡晶片的附近，利用風扇所產生的風力， 來降低這些元件的環境溫度與自身溫度。但，目前電子裝 置的設計係趨向輕、薄、短、小，若要於原先的系統中再 另外設置風扇，勢必得增加整個系統的體積與重量。 發明人爰因於此，本於積極發明之精神，亟思一種可 以解決上述問題之「色輪」，幾經研究實驗終至完成此項 嘉惠世人之發明。 【發明内容】 有鑑於上述課題，本發明之目的係提供一種解決投影 系統内高溫問題的色輪。 緣是，為達上述目的，依本發明之一種色輪，包含一 馬達、一彩色濾光片以及一風扇葉片組，其中，馬達係由 一轴心蓋與一馬達本體所組成，軸心蓋係設置於馬達本體 的一側，軸心蓋與馬達本體係沿著一中心軸旋轉；彩色濾 光片係設置於軸心蓋；風扇葉片組係具有複數個葉片，風 扇葉片組係設置於彩色濾光片。 1235878 為達上述目的，依本發明之一種色輪，包含一馬達、 一彩色濾光片以及一風扇葉片組，其中，馬達係由一軸心 蓋與一馬達本體所組成，軸心蓋係設置於馬達本體的一 侧，軸心蓋與馬達本體係沿著一中心軸旋轉；彩色濾光片 係設置於轴心蓋；風扇葉片組係具有複數個葉片，風扇葉 片組係設置於馬達的周圍。 為達上述目的，依本發明之一種色輪，包含一馬達、 一風扇葉片組以及一彩色濾光片，其中，馬達係由一軸心 蓋與一馬達本體所組成，軸心蓋係設置於馬達本體的一 侧，軸心蓋與馬達本體係沿著一中心軸旋轉；風扇葉片組 係具有複數個葉片，風扇葉片組係與馬達相連結；彩色濾 光片係與風扇葉片組相連結。 承上所述，本發明之色輪係具有一風扇葉片組，藉由 風扇葉片組的轉動，進而將投影系統内部的熱源分散，甚 至導到系統外部。與習知技術相比，本發明僅於原來的色 輪上加設風扇葉片組，利用馬達帶動彩色濾光片的轉動作 動，同時帶動風扇葉片組的轉動。由於無需外加獨立的風 扇，不僅整個系統的體積不變，重量亦增加不多，花費亦 不大，非常適合工業界使用。另外’風扇葉片組所產生的 對流亦可降低馬達的溫度，俾使色輪的使用壽命增長。再 者，由於降低了整體系統的温度，亦提昇了其餘元件的可 靠度。 【實施方式】 1235878 ’ 5兒明依據本發明較佳實施例之 以下將參照相關圖式 色輪。 光= 發明較佳實施例之色#1包含-馬達η、-彩色滤 Μ 以及一風扇葉片組13，其中，馬達11係由一軸心 ^與一馬達本體m所組成，軸心蓋lu係設置於馬 體112的一側，軸心蓋lu與馬達本體I〗〕係沿著一 、軸八旋轉;彩色濾光片12係設置於軸心蓋111;風扇 j組13係具有複數個葉片m，風扇葉片組Η係設置 於彩色濾光片12。 請參照圖1A與圖1B，馬達n係由 達本體m所組成，軸心蓋lu係設置於馬達本體^之 的—側’軸心蓋U1與馬達本體112係沿著一中心軸八旋 轉。於本實_中，馬達本體112主要係由—殼體、一磁 鐵圈（未顯示於圖）、-石夕鋼片（未顯示於圖）以及一線 圈（未顯示於圖）所組成。#_通電時，仙片係產生 磁力以及磁場，且藉由通電電流的正負與強度讓磁場發生 有序的變化，亦即為一旋轉磁場，使得磁鐵圈與旋轉磁場 作用’進而形成轉動。 另外，本實施例之彩色濾光片12可為一由紅色 '綠 色以及藍色之二色扇形濾光片所形成的圓形濾光片。另 外，彩色濾光片12亦可為一以紅、綠、藍三色之多個區 塊所形成之圓形濾光片，或亦可為一以紅、綠、藍三色加 上白色透明區塊的多個區塊所形成之圓形濾光片或是由 一圓形透明板上形成紅、綠、藍三色之多個區塊的薄膜所 1235878 、、且成。當然’如圖1B所示，彩色濾光片12亦可以是如上 述任—型態之一環型濾光片。 再者，於本實施例中，彩色濾光片12係結合於馬達 11之軸心蓋1Π上。於此，彩色濾光片12係可以黏合或 礙合等方式設置於軸心蓋⑴上。另外，彩色滤光片12 亦沿著中心軸A旋轉。 再明參妝圖1A與圖1B，彩色濾光片12係位於馬達 Π與風扇葉片組13之間，其中，風扇葉片組13係具有複 數個葉片13卜且葉片131的材質係可以是工程塑膠。當 然，葉片m的材質亦可以是橡膠、金屬、碳纖維、陶莞、 木材或複合材料。料，如圖1B所示，風扇葉片 組13亦可包含一外殼132以方便與彩色濾光片12接合。 於本實施财，風扇㈣組π與葉片131的尺寸與形狀 可依照實際需求而作調整。於此，風扇葉片組13可為一 葉片組或環形風扇葉片組。另外，風扇葉片組13 亦沿者中心軸Α旋轉。 另外，如圖2A與圖2B所+，Γ7 g _ # 所不風扇葉片組13亦可位 =::2的周圍，卜風敗㈣係為-環 另外’如圖3所示，風扇荦片 扇葉片組线置於彩色縣Z2t13料以為環形風 再請參照圖1A，於本實施例中，色輪！更包含一定位 兀件14 ’定位元件14係為一定位板 固定於投影系統中。 ’、乂將色輪1 1235878 於本實施例中，當馬達u X ^ ^ ^ ^ ^ Φ u λΊ 门士 ^碰 轉勖時，不僅常動形色濾 先片12轉動，同時亦帶動風扃 羽葉片組13的韓動。由於涵 扇葉片組13的轉動而造成系㈣冑甶於風 1么 成糸統内部產生對流，不僅分散 了系統内部的熱源，當投影系絲 又〜糸統具有開口時，更可將埶源 =系，部，藉此降低系統内部的溫度二^ 其他元件的使用壽命。另外， ^ 乃外風扇葉片組13因轉動而產 生的對流亦可降低馬達U的溫痄 心幻/皿度，亦更加延長了色輪1 的使用哥命。 再請參考圖4,本發明另一較佳實施例之色輪】，包 3馬達21、一形色滤光片22以及一風扇葉片組μ，其 中’馬達21係由-軸心蓋211與一馬達本體212所組成， 軸心蓋211係設置於馬達本體212的一側，轴心蓋川與 馬達本體212係沿著-中心μ旋轉；彩色滤光片則、 設置於軸心蓋2 i i ;風扇葉片組2 3係具有複數個葉片 231，風扇葉片組23係設置於馬達21的周圍。 於本實施例中，色輪2更包含一定位元件24，定位元 件24係為一定位板，其係用以將色輪2固定於投影系統 中。 於本實施例中’風扇葉片組23係沿著中心軸b旋轉， 且彩色濾光片22係沿著中心軸B旋轉。 另外，本實施例中之元件的特徵與功能皆與上述實施 例中之相同元件相同，在此不再贅述。 另外，本發明又一較佳實施例之色輪3，包含一馬達 31、一風扇葉片組32以及一彩色濾光片33，其中，馬達 10 1235878 31係由一軸心蓋311與一馬達本體312所組成，軸心蓋 川係設置於馬達本體312的一侧，轴心蓋3ιι與馬達本 "*係著中心軸c旋轉；風扇葉片組32係具有複 數個葉片32卜風扇葉片组32係與馬達⑴目連結；彩色 濾光片33係與風扇葉片組32相連結。 於本實施例中’色輪3更包含—定位元件34，定位元 件34係為一定位板，其係用以將色輪3固定於投影 中。 、如圖5所不，風扇葉片組32係位於彩色濾光片％與 馬達31之間。另外，如圖6所示，彩色滤光片％亦可環 ，於風«片組32。再者，如圖7料，風扇葉片組％ 係設置於馬達31的周圍。 >另外，於本實施例中，風扇葉片組32得、沿著中心軸c 方疋轉且彩色滤光片33亦沿著中心軸c旋轉。 本貫她例中之元件的特徵與功能皆與上述實施例之 相同元件相同，在此亦不再贅述。 、去另外，於本實施例中’風扇葉片組32亦可以增加馬 達31與彩色濾光片33之間的黏合面積。 承上所述’本發明之色輪係具有—風扇葉片組，藉由 風扇#組的轉動’進而將投影系統内部的熱源分散，甚 ^‘到系統外部。與習知技術相比，本發明僅於原來的色 ^上加設風扇葉片組’利用馬達帶動彩色滤光片的轉動作 ’㈣帶動風扇葉片組的轉動。由於無需外加獨立的風 羽’不僅整個系統的體積不變，重量亦增加不多，花費亦 1235878 不大，非常適合工業界使用。另外，風扇葉片組所產生的 對流亦可降低馬達的溫度，俾使色輪的使用壽命增長。再 者，由於降低了整體系統的溫度，亦提昇了其餘元件的可 靠度。 以上所述僅為舉例性，而非為限制性者。任何未脫離 本發明之精神與範疇，而對其進行之等效修改或變更，均 應包含於後附之申請專利範圍中。 【圖式簡單說明】 圖1A係為本發明較佳實施例之色輪的一側視示意 圖， 圖1B係為本發明較佳實施例之色輪的一上視示意圖； 圖2A係為本發明較佳實施例之色輪的一剖面示意圖； 圖2B係為本發明較佳實施例之色輪的一上視示意圖； 圖3係為本發明較佳實施例之色輪的又一上視示意 圖， 圖4係為本發明另一較佳實施例之色輪的一剖面示意 圖； 圖5係為本發明又一較佳實施例之色輪的一側視示意 圖；以及 圖6與圖7係為本發明又一較佳實施例之色輪的另一 組剖面示意圖。 元件符號說明： 12 1235878 1 色輪 11 馬達 111 轴心蓋 112 馬達本體 12 彩色濾、光片 13 風扇葉片組 131 葉片 132 外殼 14 定位元件 2 色輪 21 馬達 211 軸心蓋 212 馬達本體 22 彩色濾光片 23 風扇葉片組 231 葉片 24 定位元件 3 色輪 31 馬達 311 轴心蓋 312 馬達本體 32 風扇葉片組 321 葉片 33 彩色濾光片 1235878 34 定位元件 A、B、C 中心軸 141235878 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a color wheel, especially a color wheel applied to a projection system. [Previous technology] Due to the multiple requirements of large display area, miniaturization and light weight system, the image projection system has become the most popular sub-item in the optoelectronic industry. Currently, there are three types of popular projection systems, which are liquid crystals. A Liquid Crystal Display Projector (LCD), a Liquid Crystal on Silicon (LCoS), and a Digital Light Processing (DLP). Among them, LCoS and DLP have the advantages of system simplification, and DLP will be used as an example for illustration below. DLP projectors are digitally controlled and operate using the principle of reflected light. First, the light source collects light through a light integration rod (Light Integration Rod), splits it through a color filter in the color wheel, and projects it onto a digital micromirror device (DMD). In this technology, a digital micromirror chip is used to replace the LCD panel in traditional LCD projectors, which is responsible for presenting images. Because the digital micromirror wafer has many tiny movable lenses, the driving electrodes are used to control the tilt angle and deflection time of the movable lens, and the image is projected by the lens by switching the reflection direction of the light. Among them, the color wheel system is composed of a color filter that is adhered to the motor 1235878 with an adhesive, and then the color filter is rotated along the center by the motor. However, as the temperature of the light source in the system is often as high as 950 ° C to 1000 ° C, the operating temperature of the overall projection system is also high. Since the adhesive is easily brittle at high temperatures, the high temperature generated by the light source not only reduces the life of the color wheel, but also affects the reliability of other components. To solve this problem, the current practice is to set the fan near the light source, color source, and digital micromirror chip, and use the wind generated by the fan to reduce the ambient temperature and the temperature of these components. However, the current design of electronic devices tends to be light, thin, short, and small. If an additional fan is to be installed in the original system, the volume and weight of the entire system must be increased. Because of this, the inventor, based on the spirit of active invention, is thinking about a "color wheel" that can solve the above problems. After several research experiments, he has completed this invention that benefits the world. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a color wheel that solves the problem of high temperature in a projection system. The reason is that, in order to achieve the above-mentioned object, a color wheel according to the present invention includes a motor, a color filter, and a fan blade set.

On one side of the motor body, the shaft cover and the motor system rotate along a central axis; the color filter is provided on the shaft cover; the fan blade system has a plurality of blades, and the fan blade system is arranged around the motor . To achieve the above object, a color wheel according to the present invention includes a motor, a fan blade group, and a color filter.

On one side of the motor body, the shaft cover and the motor rotate along a central axis; the fan blade system has a plurality of blades, and the fan blade system is connected to the motor; and the color filter system is connected to the fan blade group. According to the above description, the color wheel system of the present invention has a fan blade group, and the fan blade group is rotated to further disperse the heat source inside the projection system and even lead it to the outside of the system. Compared with the conventional technology, the present invention only adds a fan blade set to the original color wheel, and uses a motor to drive the rotation of the color filter, and at the same time drives the fan blade set to rotate.
