Description
本發明是有關於一種色輪及應用其之投影機，且特別是有關於一種具有凹槽之色輪及應用其之投影機。The present invention relates to a color wheel and a projector using the same, and more particularly to a color wheel having a groove and a projector for applying the same.
以投影機採用汞燈來作為發光源而言，由於汞燈的部份發光頻譜表現不佳而降低了產生之影像的品質，因此，目前部份之投影機藉由雷射光源作為發光源。雷射光源產生雷射光之後，雷色光經由色輪進行分色，以透過數位微鏡裝置來產生全彩的畫面。In the case of a projector using a mercury lamp as a light source, the quality of the image produced is reduced due to the poor performance of the partial light emission spectrum of the mercury lamp. Therefore, some projectors currently use a laser light source as a light source. After the laser source produces the laser light, the thunder light is separated by the color wheel to generate a full-color picture through the digital micro-mirror device.
一般來說，色輪係由膠材、螢光粉及玻璃所製成。螢光粉與膠材係相互混合，以塗佈且黏附在玻璃上。然而，由於雷射光的能量大且功率高，因此，當雷射光聚焦而投射到色輪時，膠材很可能會碳化而形成黑點。如此一來，一旦雷射光投射到色輪上的黑點時，雷射光係無法通過色輪，使得畫面會閃爍而降低品質。In general, the color wheel is made of glue, phosphor and glass. The phosphor powder and the gum are mixed with each other to coat and adhere to the glass. However, since the energy of the laser light is large and the power is high, when the laser light is focused and projected onto the color wheel, the rubber material is likely to be carbonized to form a black spot. As a result, once the laser light is projected onto the black spot on the color wheel, the laser light cannot pass through the color wheel, causing the picture to flicker and degrade the quality.
因此，如何提供一種讓雷射光投射到色輪時，可避免膠材碳化而對應地提升畫面的品質，乃為相關業者努力之課題之一。Therefore, how to provide a kind of laser light to be cast to the color wheel can avoid the carbonization of the rubber material and correspondingly improve the quality of the picture, which is one of the subjects of the related industry.
本發明係有關於一種色輪及應用其之投影機，其藉由凹槽來容置螢光粉，以提高畫面的品質。The invention relates to a color wheel and a projector using the same, which accommodates phosphor powder by a groove to improve the quality of the picture.
根據本發明，提出一種色輪，包括一主體及一蓋體。主體具有一凹槽及一穿透部。凹槽僅環繞部份之主體的周緣，用以容置一螢光粉。穿透部對應到未被凹槽環繞之另一部分之主體的周緣，且位於凹槽之兩個相對內壁間。蓋體設置於主體上且覆蓋凹槽。當一光線投射至主體的穿透部時，一第一色光係經由主體之穿透部投射出，或當光線投射到螢光粉時，光線係激發螢光粉而投射出一第二色光。第二色光的顏色相異於第一色光的顏色。According to the present invention, a color wheel is provided that includes a body and a cover. The body has a recess and a penetration. The groove only surrounds the periphery of the body of the portion for accommodating a phosphor. The penetrating portion corresponds to the circumference of the body of the other portion not surrounded by the groove and is located between the two opposite inner walls of the groove. The cover body is disposed on the main body and covers the groove. When a light is projected onto the penetrating portion of the body, a first color light is projected through the penetrating portion of the body, or when the light is projected onto the phosphor powder, the light system excites the phosphor powder to project a second color light. . The color of the second color light is different from the color of the first color light.
根據本發明，再提出一種投影機，包括一色輪、一馬達、一數位微鏡裝置、一鏡頭及一光源。色輪包括一主體及一蓋體。主體具有一凹槽，凹槽用以容置一螢光粉。蓋體設置於主體上且覆蓋凹槽。馬達連接於色輪，用以帶動色輪轉動。光源用以產生一光線，光線激發螢光粉產生一第一色光至數位微鏡裝置而投射至鏡頭，以產生一影像。According to the present invention, a projector is further provided, comprising a color wheel, a motor, a digital micromirror device, a lens and a light source. The color wheel includes a body and a cover. The main body has a groove for receiving a phosphor powder. The cover body is disposed on the main body and covers the groove. The motor is connected to the color wheel to drive the color wheel to rotate. The light source is used to generate a light, and the light excites the phosphor to generate a first color light to the digital micromirror device and is projected onto the lens to generate an image.
為了對本發明之上述及其他方面有更佳的瞭解，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下：In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:
請參照第1A、1B、2A及2B圖，第1A圖繪示根據本發明第一實施例之色輪的組設圖，第1B圖繪示第1A圖中之色輪的***圖，第2A圖繪示沿著第1A圖中之剖面線2-2’的色輪於光線投射到穿透部時之剖面圖，且第2B圖繪示於第2A圖中之色輪轉動後光線投射到凹槽時之剖面圖。Please refer to FIGS. 1A, 1B, 2A and 2B, FIG. 1A is a diagram showing the arrangement of the color wheel according to the first embodiment of the present invention, and FIG. 1B is a diagram showing the explosion of the color wheel in FIG. 1A, FIG. 2A. The figure shows a cross-sectional view of the color wheel along the section line 2-2' in FIG. 1A when the light is projected onto the penetrating portion, and FIG. 2B shows the light beam projected to the color wheel in FIG. 2A after the color wheel is rotated. A cross-sectional view of the groove.
色輪110包括主體111及蓋體113。主體111具有凹槽111r，凹槽111r用以容置螢光粉f1。蓋體113設置於主體111上且覆蓋凹槽111r。The color wheel 110 includes a main body 111 and a cover 113. The main body 111 has a groove 111r for accommodating the fluorescent powder f1. The cover 113 is disposed on the main body 111 and covers the groove 111r.
於本實施例中，凹槽111r環繞至少部份之主體111的周緣。此處係以凹槽111r僅環繞部分之主體111的周緣為例說明。也就是說，凹槽111r僅對應於部份之主體111的周緣。此外，主體111更具有穿透部111p。穿透部111p對應到未被凹槽111r環繞之另一部分之主體111的周緣，且位於凹槽111r之兩個相對內壁111rs間。In the present embodiment, the groove 111r surrounds the periphery of at least a portion of the body 111. Here, the circumference of the main body 111 in which the groove 111r surrounds only a portion is exemplified. That is, the groove 111r corresponds only to the circumference of the portion of the body 111. Further, the main body 111 further has a penetrating portion 111p. The penetrating portion 111p corresponds to the periphery of the body 111 of the other portion not surrounded by the groove 111r, and is located between the opposite inner walls 111rs of the groove 111r.
本實施例之色輪110係更包括膠體層115，配置於主體111與蓋體113之間，以貼合主體111與蓋體113。本實施例之膠體層115對應至主體111之凹槽111r及穿透部111p以外的區域。The color wheel 110 of the embodiment further includes a colloid layer 115 disposed between the main body 111 and the lid 113 to adhere the main body 111 and the lid 113. The colloid layer 115 of the present embodiment corresponds to a region other than the groove 111r and the penetrating portion 111p of the main body 111.
如第2A及2B圖所示，當光線L11投射至色輪110之不同位置時，下述的兩種情況可能會發生。如第2A圖所示，當光線L11投射至主體111之穿透部111p時，第一色光L11’係經由主體111之穿透部111p投射出。或者，如第2B圖所示，當光線L11投射至螢光粉f1時，光線L11激發螢光粉f1而投射出第二色光L12。第二色光L12的顏色相異於第一色光L11’的顏色。As shown in FIGS. 2A and 2B, when the light L11 is projected to different positions of the color wheel 110, the following two cases may occur. As shown in Fig. 2A, when the light ray L11 is projected onto the penetrating portion 111p of the main body 111, the first color light L11' is projected through the penetrating portion 111p of the main body 111. Alternatively, as shown in FIG. 2B, when the light ray L11 is projected to the phosphor powder f1, the light ray L11 excites the phosphor powder f1 and projects the second color light L12. The color of the second color light L12 is different from the color of the first color light L11'.
一般來說，以往的色輪係藉由螢光粉與膠材相互混合來塗佈在玻璃上而製成。當雷射光投射到此色輪時，能量大且功率大的雷射光往往易導致膠材碳化。相較之下，若欲透過本實施例之色輪110取得第二色光L12時，由於本實施例係以主體111之凹槽111r來容置螢光粉f1，且膠體層115位於主體111之凹槽111r以外的區域，因此，第二色光L12係透過光線L11(例如是雷射光)投射到凹槽111r處來激發螢光粉f1而產生。換言之，光線L11及第二色光L12皆不會經過膠體層115，而可避免膠體層115產生碳化的情況。另外，若欲透過本實施例之色輪110取得第一色光L11’時，由於本實施例之膠體層115更位於主體111之穿透部111p以外的區域，因此，第一色光L11’係經由主體111之穿透部111p投射出。換言之，光線L11及第一色光L11’不會經過膠體層115，而可避免膠體層115產生碳化的情況。In general, a conventional color wheel is produced by coating a phosphor powder and a rubber material on a glass. When laser light is projected onto the color wheel, the laser light with high energy and high power tends to cause carbonization of the rubber material. In the embodiment, the second color light L12 is obtained by the color wheel 110 of the embodiment. In this embodiment, the fluorescent powder f1 is received by the recess 111r of the main body 111, and the colloid layer 115 is located in the main body 111. A region other than the groove 111r, therefore, the second color light L12 is generated by the light ray L11 (for example, laser light) projected onto the groove 111r to excite the phosphor powder f1. In other words, neither the light L11 nor the second color light L12 passes through the colloid layer 115, and the carbonization of the colloid layer 115 can be avoided. In addition, when the first color light L11' is to be obtained by the color wheel 110 of the present embodiment, since the colloid layer 115 of the present embodiment is located further than the penetration portion 111p of the main body 111, the first color light L11' It is projected through the penetrating portion 111p of the body 111. In other words, the light ray L11 and the first color light L11' do not pass through the colloid layer 115, and the carbonization of the colloid layer 115 can be prevented.
本實施例之蓋體113的材料為可透光材料，例如是玻璃，以應用於穿透式投影機中(說明於第二實施例)。此技術領域中具有通常知識者應明瞭，蓋體113之材料可根據所欲之投影機的形式來決定。以所欲之投影機為反射式投影機來說，蓋體113之材料可例如是光反射材料，例如是鋁板或具有鏡面之結構(說明於第三實施例)。The material of the cover 113 of the present embodiment is a light permeable material, such as glass, for use in a transmissive projector (described in the second embodiment). It will be apparent to those of ordinary skill in the art that the material of the cover 113 can be determined depending on the form of the desired projector. In the case where the desired projector is a reflective projector, the material of the cover 113 may be, for example, a light reflective material such as an aluminum plate or a mirrored structure (described in the third embodiment).
請參照第3A圖及第3B圖，其繪示根據本發明第二實施例之穿透式投影機的色輪產生第一色光及第二色光的示意圖。Please refer to FIG. 3A and FIG. 3B , which are schematic diagrams showing the first color light and the second color light generated by the color wheel of the penetrating projector according to the second embodiment of the present invention.
第3A及3B圖中之色輪210的結構係類似於第一實施例之色輪110的結構，因此，此處並不重複說明。由於色輪210係應用在穿透式投影機200中，因此，色輪210的蓋體213的材料係為可透光材料，例如是玻璃。The structure of the color wheel 210 in the drawings 3A and 3B is similar to that of the color wheel 110 of the first embodiment, and therefore, the description thereof will not be repeated here. Since the color wheel 210 is applied to the transmissive projector 200, the material of the cover 213 of the color wheel 210 is a light permeable material such as glass.
穿透式投影機200包括色輪210、馬達220、數位微鏡裝置230、鏡頭240及光源250。馬達220連接於色輪210，用以帶動色輪210轉動。光源250用以產生光線L21。The transmissive projector 200 includes a color wheel 210, a motor 220, a digital micromirror device 230, a lens 240, and a light source 250. The motor 220 is coupled to the color wheel 210 for driving the color wheel 210 to rotate. The light source 250 is used to generate light L21.
當光線L21投射至主體211之穿透部211p時，第一色光L21’係經由主體211的穿透部211p投射出(第3A圖所示)。或者，當光線L21投射至主體211之凹槽211r內的螢光粉f21時，光線L21激發螢光粉f21而投射出第二色光L22(第3B圖所示)。如此一來，第一色光L21’或第二色光L22再穿透過為可透光材料的蓋體213，以藉由數位微鏡裝置230投射至鏡頭240而產生影像。換言之，無論是第一色光L21’或第二色光L22之取得，皆無需經過膠體層215，因此，本實施例之穿透式投影機200係可避免以往之色輪產生膠材碳化的情況，使得穿透式投影機200所產生的影像之品質良好。When the light ray L21 is projected onto the penetrating portion 211p of the body 211, the first color light L21' is projected through the penetrating portion 211p of the body 211 (shown in Fig. 3A). Alternatively, when the light ray L21 is projected onto the phosphor powder f21 in the groove 211r of the main body 211, the light ray L21 excites the luminescent powder f21 and projects the second color light L22 (shown in FIG. 3B). In this way, the first color light L21' or the second color light L22 penetrates through the cover 213 which is a light permeable material to be projected onto the lens 240 by the digital micromirror device 230 to generate an image. In other words, whether the first color light L21' or the second color light L22 is obtained does not need to pass through the colloid layer 215. Therefore, the transmissive projector 200 of the embodiment can avoid the carbonization of the rubber material of the conventional color wheel. The quality of the image produced by the transmissive projector 200 is good.
第3A及3B圖中之光行進路線皆以先穿透過主體211，再穿透過蓋體213為例說明。然而，於其他實施例中，色輪210亦可反向配置，使得光行進路線係為先穿透過蓋體213，再穿透過主體211。The light travel routes in FIGS. 3A and 3B are first described by penetrating through the main body 211 and then penetrating through the cover 213. However, in other embodiments, the color wheel 210 can also be reversely configured such that the light travel path penetrates the cover 213 first and then passes through the body 211.
此外，雖然第3A及3B圖中未繪示出例如是聚焦透鏡、光整合元件(light integrator)或稜鏡之光學元件，然而，此技術領中具有通常知識者應明瞭，光學元件係可配置於本實施例之穿透式投影機200中，以提供例如是聚光或導光之效果。In addition, although the optical elements such as a focusing lens, a light integrator or a cymbal are not shown in FIGS. 3A and 3B, it should be understood by those skilled in the art that the optical components are configurable. In the transmissive projector 200 of the present embodiment, an effect such as collecting light or guiding light is provided.
請參照第4A圖及第4B圖，其繪示根據本發明第三實施例之反射式投影機的色輪產生第一色光及第二色光的示意圖。Please refer to FIG. 4A and FIG. 4B , which are schematic diagrams showing the first color light and the second color light generated by the color wheel of the reflective projector according to the third embodiment of the present invention.
第4A及4B圖中之色輪310的結構係類似於第一實施例之色輪110的結構，因此，此處並不重複說明。由於色輪310係應用在反射式投影機300中，因此，色輪310之蓋體313的材料係為光反射材料，例如是鋁板或具有鏡面之結構。The structure of the color wheel 310 in Figs. 4A and 4B is similar to that of the color wheel 110 of the first embodiment, and therefore, the description thereof will not be repeated here. Since the color wheel 310 is applied to the reflective projector 300, the material of the cover 313 of the color wheel 310 is a light reflective material such as an aluminum plate or a mirrored structure.
反射式投影機300包括色輪310、馬達320、數位微鏡裝置330、鏡頭340、光源350及分光鏡(dichroic mirror)360。馬達320連接於色輪310，用以帶動色輪310轉動。光源350用以產生光線L31a，且經由分光鏡360導引至色輪310。The reflective projector 300 includes a color wheel 310, a motor 320, a digital micromirror device 330, a lens 340, a light source 350, and a dichroic mirror 360. The motor 320 is coupled to the color wheel 310 for driving the color wheel 310 to rotate. The light source 350 is used to generate the light L31a and is guided to the color wheel 310 via the beam splitter 360.
如第4A圖所示，當光線L31a投射到色輪310時，第一色光L31a’經由主體311之穿透部311p投射出。為光反射材料之蓋體313係反射第一色光L31a’而產生第一色光L31b。第一色光L31b經由分光鏡360投射到數位微鏡裝置330，以再投射到鏡頭340而產生影像。As shown in Fig. 4A, when the light ray L31a is projected onto the color wheel 310, the first color light L31a' is projected through the penetrating portion 311p of the body 311. The cover 313, which is a light-reflecting material, reflects the first color light L31a' to generate the first color light L31b. The first color light L31b is projected to the digital micromirror device 330 via the beam splitter 360 to be re-projected to the lens 340 to generate an image.
如第4B圖所示，當光線L31a投射到主體311之凹槽311r內的螢光粉f22時，光線L31a激發螢光粉f22而投射出第二色光L32a。為光反射材料之蓋體313係反射第二色光L32a而產生第二色光L32b。第二色光L32b係經由分光鏡360投射至數位微鏡裝置330，以再投射到鏡頭340而產生影像。As shown in FIG. 4B, when the light ray L31a is projected onto the phosphor powder f22 in the groove 311r of the main body 311, the light ray L31a excites the phosphor powder f22 and projects the second color light L32a. The cover 313, which is a light-reflecting material, reflects the second color light L32a to generate the second color light L32b. The second color light L32b is projected to the digital micromirror device 330 via the beam splitter 360 to be re-projected to the lens 340 to generate an image.
如此一來，無論是第一色光L31b或第二色光L32b之取得，皆無需經過膠體層315，因此，本實施例之反射式投影機300係可避免以往之色輪產生膠材碳化的情況，使得反射式投影機300所產生的影像之品質良好。In this way, the first color light L31b or the second color light L32b is obtained without passing through the colloid layer 315. Therefore, the reflective projector 300 of the embodiment can avoid the case where the color wheel of the conventional color wheel produces carbonization. The quality of the image produced by the reflective projector 300 is good.
雖然第4A及4B圖中係繪示出分光鏡360來做說明，然而，此技術領中具有通常知識者應明瞭，其他之光學元件亦可配置於本實施例之反射式投影機300中，以提供例如是聚光或導光之效果。另外，光線L31a及第一色光L31b，以及第一色光L31a’與第一色光L31b係於第4A圖中略微地錯開，且第4B圖中之光線L31a與第二色光L32b，以及第二色光L32a及第二色光L32b係略微地錯開，以清楚地表達出各個光路位置。Although the spectroscope 360 is illustrated in FIGS. 4A and 4B for illustration, it should be apparent to those skilled in the art that other optical components may be disposed in the reflective projector 300 of the present embodiment. To provide, for example, the effect of concentrating or guiding light. In addition, the light L31a and the first color light L31b, and the first color light L31a' and the first color light L31b are slightly shifted in FIG. 4A, and the light L31a and the second color light L32b in FIG. 4B, and The dichromatic light L32a and the second color light L32b are slightly shifted to clearly express the respective optical path positions.
請參照第5A~5C圖，第5A圖繪示根據本發明第四實施例之色輪的前視圖，第5B圖繪示沿著第5A圖中之剖面線A-A’的色輪於光線投射到凹槽的第一區塊時之剖面圖，且第5C圖繪示於第5B圖中之色輪轉動後光線投射到凹槽的第二區塊時之剖面圖。5A-5C, FIG. 5A is a front view of a color wheel according to a fourth embodiment of the present invention, and FIG. 5B is a color wheel along the section line A-A' of FIG. 5A. A cross-sectional view of the first block when projected onto the groove, and FIG. 5C is a cross-sectional view of the second block when the color wheel is rotated after the color wheel is rotated in FIG. 5B.
相較於第一實施例之色輪110，本實施例之色輪410的凹槽411r包含第一區塊411r1及第二區塊411r2。第一區塊411r1用以容置螢光粉f31，且第二區塊411r2用以容置螢光粉f32。Compared with the color wheel 110 of the first embodiment, the groove 411r of the color wheel 410 of the present embodiment includes a first block 411r1 and a second block 411r2. The first block 411r1 is for accommodating the phosphor powder f31, and the second block 411r2 is for accommodating the phosphor powder f32.
如第5B圖所示，當光線L40投射至螢光粉f31時，光線L40激發第一區塊411r1內之螢光粉f31產生第一色光L41。或者，如第5C圖所示，當光線L40投射至螢光粉f32時，光線L40激發第二區塊411r2內之螢光粉f32產生第二色光L42。第二色光L42的顏色相異於第一色光L41的顏色。換言之，藉由填充不同種類之螢光粉f31及f32於凹槽411r之第一區塊411r1及第二區塊411r2中，不同顏色之色光(第一色光L41及第二色光L42)係可產生，以增加色輪410可提供不同顏色之色光的數量而提高色輪410之實用性及應用面。As shown in FIG. 5B, when the light ray L40 is projected to the phosphor powder f31, the light ray L40 excites the phosphor powder f31 in the first block 411r1 to generate the first color light L41. Alternatively, as shown in FIG. 5C, when the light ray L40 is projected to the phosphor powder f32, the light ray L40 excites the phosphor powder f32 in the second block 411r2 to generate the second color light L42. The color of the second color light L42 is different from the color of the first color light L41. In other words, by filling different types of phosphors f31 and f32 in the first block 411r1 and the second block 411r2 of the groove 411r, color lights of different colors (the first color light L41 and the second color light L42) can be The utility model and the application surface are improved to increase the number of color lights of the color wheel 410 that can provide different colors.
根據本發明上述實施例之色輪及應用其之投影機，其藉由凹槽來容置螢光粉，且膠體層配置於主體之凹槽以外的區域，以避免膠體層被高功率之光線照射而產生碳化的情況。如此一來，應用上述實施例之色輪的投影機係可產生良好的投影影像。於一實施例中，膠體層除了配置於主體之凹槽以外的區域外，更配置於主體之穿透部以外的區域，以進一步避免膠體層碳化的情況。於另一實施例中，凹槽包括兩個區塊，以可容置不同之螢光粉。如此一來，當光線激發此兩個區塊內之螢光粉時，不同顏色之色光係可產生，以增加色輪之實用性及應用面。According to the color wheel of the above embodiment of the present invention and the projector using the same, the phosphor powder is accommodated by the groove, and the colloid layer is disposed in a region other than the groove of the main body to prevent the colloid layer from being irradiated with high power. The case of carbonization by irradiation. As a result, the projector using the color wheel of the above embodiment can produce a good projected image. In one embodiment, the colloid layer is disposed outside the region other than the groove of the main body, and is disposed outside the penetration portion of the main body to further avoid carbonization of the colloid layer. In another embodiment, the recess includes two blocks to accommodate different phosphors. In this way, when the light stimulates the phosphor powder in the two blocks, different color light systems can be generated to increase the practicality and application surface of the color wheel.
