Description
本發明係有關於一種光學色輪組件及其光學色輪，尤指一種用於投影裝置上的光學色輪組件及其光學色輪。 The present invention relates to an optical color wheel assembly and optical color wheel thereof, and more particularly to an optical color wheel assembly for use on a projection device and an optical color wheel thereof.
投影機的特點之一乃是由於不需要固定的螢幕，因此不會被螢幕大小所限制，只要有一可用來投射影像的平面，即可輕易地投射出大尺寸的畫面。因此，已被廣泛的應用到各個領域，例如應用於大型會議演講上以投影機放大欲投影的畫面，或是應用於家庭劇院組。 One of the features of the projector is that it does not require a fixed screen, so it is not limited by the size of the screen. As long as there is a plane for projecting images, a large size image can be easily projected. Therefore, it has been widely applied to various fields, such as a large-scale conference presentation with a projector to enlarge a picture to be projected, or applied to a home theater group.
目前一般常見之投影機，乃利用被投影機內的高速馬達所驅動的色輪(Color filter或Color wheel)來完成對色彩之分離與處理。而傳統的色輪結構，用來藍光雷射光源穿透的部分，多為利用開設一槽體的方式來使藍光雷射光源穿透。雖然這種開設槽體的方式能夠使得藍光雷射完全穿透，不會有光源效率降低的問題，然而，此種開設槽體讓藍光雷射穿透的方式，容易因為色輪的高速旋轉，進而產生風切噪音，舉例來說，其噪音值可能高達80至90分貝。 At present, the common projector is to use the color wheel (Color filter or Color wheel) driven by the high speed motor in the projector to complete the separation and processing of colors. The traditional color wheel structure, which is used for the penetration of the blue laser light source, mostly uses a slot to penetrate the blue laser light source. Although the way of opening the trough can completely penetrate the blue laser, there is no problem that the efficiency of the light source is reduced. However, the way in which the trough is made to allow the blue laser to penetrate is easy to rotate due to the high speed of the color wheel. In turn, wind-cut noise is generated, for example, the noise value may be as high as 80 to 90 decibels.

In other words, the first side 1211 of the through hole 121 is joined to the first side wing portion 21 of the light transmitting unit 2, and the second side 1212 of the through hole 121 is joined to the second side wing portion 22 of the light transmitting unit 2, through the hole 121 The third side 1213 is joined to the third side wing portion 23 of the light transmitting unit 2, and the fourth side edge of the through hole 121 is joined to the fourth side wing portion 24 of the light transmitting unit 2. Therefore, the shape of the through hole 121 and the light transmitting unit 2 is roughly the same. Thereby, the light transmitting unit 2 can be directly embedded in the through hole 121 such that the light transmitting unit 2 is surrounded by the closed through hole 121 and completely sandwiched by the through hole 121.
此外，更進一步來說，請同時參閱圖2C至2D所示，圖2C為本發明第二實施例的光學色輪組件及其光學色輪的另外一立體分解示意圖，圖2D為本發明第二實施例的光學色輪組件及其光學色輪的另外一立體組合示意圖。以本發明第二實施例而言，貫穿孔洞121的數量可為複數個，透光單元2的數量可為複數個。舉例來說，如圖2C至2D所示，光學色輪C”中的基底單元1可再包括另外一貫穿孔洞121及另外一透光單元2，兩個貫穿孔洞121可彼此相對應設置，然本發明不以此為限。換言之，貫穿孔洞121的數量與透光單元2的數量彼此相互對應，亦即，貫穿孔洞121及透光單元2設置於基底單元1上的數量可以相同。 In addition, further, please refer to FIG. 2C to FIG. 2D, FIG. 2C is another perspective exploded view of the optical color wheel assembly and the optical color wheel thereof according to the second embodiment of the present invention, and FIG. 2D is the second embodiment of the present invention. A schematic diagram of another three-dimensional combination of the optical color wheel assembly of the embodiment and its optical color wheel. In the second embodiment of the present invention, the number of the through holes 121 may be plural, and the number of the light transmitting units 2 may be plural. For example, as shown in FIGS. 2C to 2D, the base unit 1 in the optical color wheel C" may further include another consistent through hole 121 and another light transmitting unit 2, and the two through holes 121 may be disposed corresponding to each other. The present invention is not limited thereto. In other words, the number of the through holes 121 and the number of the light transmitting units 2 correspond to each other, that is, the number of the through holes 121 and the light transmitting unit 2 disposed on the base unit 1 may be the same.
綜上所陳，當光學色輪(C’,C”)被投影機內的高速馬達所驅動時，由於透光單元2的每一個側翼部都被貫穿孔洞121的每一個側邊所環繞而夾合，使得透光單元2不會在高速旋轉的情況下飛旋而出。更詳細地說，由於貫穿孔洞121的第四側邊1214乃設置於基底單元1的側端部131上，藉此，當光學色輪(C’,C”)在高速旋轉的情況下，透光單元2可通過側端部131的頂抵，而可以緊 固於貫穿孔洞121內。此外，透光單元2的每一個側翼部(21,22,23,24)與貫穿孔洞121的每一個側邊(1211,1212,1213,1214)之間還可以再通過一黏膠(圖未示)將其彼此更牢固地貼合在一起，而可以有助於避免透光單元2飛片的情形產生。進一步來說，通過在貫穿孔洞121設置有一透光單元2，也可以使光學色輪(C’,C”)在高速旋轉的情況下所產生的風切噪音，降低置60至70分貝。 In summary, when the optical color wheel (C', C") is driven by the high speed motor in the projector, since each side wing portion of the light transmitting unit 2 is surrounded by each side of the through hole 121, The sandwiching is such that the light transmitting unit 2 does not fly out at a high speed. In more detail, since the fourth side 1214 of the through hole 121 is provided on the side end portion 131 of the base unit 1, When the optical color wheel (C', C") is rotated at a high speed, the light transmitting unit 2 can be abutted by the top end portion 131, and can be tight It is fixed in the through hole 121. In addition, each of the side flap portions (21, 22, 23, 24) of the light transmitting unit 2 and each of the side edges (1211, 1212, 1213, 1214) of the through hole 121 may further pass a glue (Fig. Shows that they are more firmly attached to each other, and can help to avoid the situation in which the light transmitting unit 2 is flying. Further, by providing the light transmitting unit 2 in the through hole 121, the wind cut noise generated by the optical color wheel (C', C") at the time of high speed rotation can be lowered by 60 to 70 decibels.
進一步來說，為了提高投影機藍光雷射光源在設置有透光單元2的透光區域12上的穿透率，透光單元2上可設置有一介電層25，介電層25可通過例如化學氣相沉積儀或濺鍍等薄膜技術來設置於透光單元2的表面上。舉例來說，介電層25可以為五氧化二鈮(Nb2O5)、二氧化鈦(TiO2)或二氧化矽(SiO2)所組成的多層膜結構，其中該多層膜結構可採用以五氧化二鈮及二氧化矽的交疊層(alternate layers)。 Further, in order to improve the transmittance of the blue laser light source of the projector on the light-transmitting region 12 provided with the light-transmitting unit 2, the light-transmitting unit 2 may be provided with a dielectric layer 25, for example, the dielectric layer 25 may be A thin film technique such as chemical vapor deposition or sputtering is provided on the surface of the light transmitting unit 2. For example, the dielectric layer 25 may be a multilayer film structure composed of niobium pentoxide (Nb 2 O 5 ), titanium dioxide (TiO 2 ) or cerium oxide (SiO 2 ), wherein the multilayer film structure may be used in five Alternate layers of cerium oxide and cerium oxide.
另外，考慮到一不同的面向，當透光單元2設置於貫穿孔洞121的過程中，由於投影機藍光雷射光源穿透介電層25與透光單元2的順序對於所穿透的藍光雷射光源可能會有所影響，因此，以正確的方向設置透光單元2於貫穿孔洞121內是非常重要的，藉此，可以賦予透光單元2及貫穿孔洞121有著特殊的幾何形狀，使得透光單元2的設置方向不至於相反。 In addition, in consideration of a different orientation, when the light transmissive unit 2 is disposed in the through hole 121, the sequence of the blue laser light source penetrating the dielectric layer 25 and the light transmissive unit 2 is penetrated by the blue light. The light source may have an influence. Therefore, it is very important to arrange the light transmitting unit 2 in the through hole 121 in the correct direction, thereby providing the light transmitting unit 2 and the through hole 121 with a special geometric shape. The arrangement direction of the light unit 2 is not reversed.
本發明第二實施例所提供的一種光學色輪(C’,C”)，通過將光學色輪(C’,C”)上的貫穿孔洞121以一側端部封閉，並同時通過在貫穿孔洞121上設置有一透光單元2，能夠降低光學色輪在高速旋轉的情況下所產生的噪音。且通過基底單元1上的側端部131以頂抵透光單元2，以防止透光單元2在光學色輪(C’,C”)的高速旋轉下而旋出。此外，通過設置在透光單元2上的介電層25，能夠提高投影機藍光雷射光源的穿透率。 An optical color wheel (C', C") provided by the second embodiment of the present invention is closed at one end by the through hole 121 on the optical color wheel (C', C"), and simultaneously passes through A light transmitting unit 2 is disposed on the hole 121, which can reduce noise generated when the optical color wheel rotates at a high speed. And passing through the side end portion 131 on the base unit 1 to abut against the light transmitting unit 2 to prevent the light transmitting unit 2 from being unscrewed under the high speed rotation of the optical color wheel (C', C"). The dielectric layer 25 on the light unit 2 can increase the transmittance of the projector's blue laser light source.
