Description
本發明是有關於一種色輪裝置,特別是有關於一種應用於投影機中的色輪裝置。The present invention relates to a color wheel device, and more particularly to a color wheel device for use in a projector.
自投影機出現以後,隨著科技的發展被運用到各種領域,由消費性產品至高科技產品,其應用範圍一直在擴展當中,例如應用於大型會議演講上以投影系統放大投影物,或是應用於商業上之投影式螢幕或電視,以配合簡報之內容做即時圖式畫面之呈現。Since the advent of the projector, with the development of technology, it has been applied to various fields, from consumer products to high-tech products, its application range has been expanding, for example, for large-scale conference presentations to project projections with projection systems, or applications. For commercial projection screens or TVs, to match the content of the newsletter for instant graphic presentation.
常見的投影機架構大致可以分為光源模組及光學處理單元。光源模組一般係由光源發光,經由光學構件收集光線,經過濾鏡、色輪的濾光處理,將處理後之光線射向光學處理單元後投射至投影幕。隨著投影機的發展,亦有在光源模組中使用雷射光源搭配塗有螢光粉的色輪,以提供不同波長的光線。The common projector architecture can be roughly divided into a light source module and an optical processing unit. The light source module is generally illuminated by a light source, collects light through the optical member, and is filtered by the filter and the color wheel, and the processed light is directed to the optical processing unit and then projected to the projection screen. With the development of projectors, there are also laser light sources in the light source module with a color wheel coated with phosphor to provide different wavelengths of light.
然而,由於雷射光束的能量較為集中,使得色輪在接收雷射光束時,光斑上的單位能量密度甚大,產生極高的溫度,因而導致螢光粉損毀或發光效率降低。隨著投影機亮度需求的提升,雷射光束之能量亦隨之增加,此種螢光粉因溫度過高而損毀或發光效率降低的現象會越來越明顯。However, due to the concentrated energy of the laser beam, when the color wheel receives the laser beam, the unit energy density on the spot is very large, resulting in extremely high temperature, thereby causing the phosphor powder to be destroyed or the luminous efficiency to be lowered. As the brightness requirement of the projector increases, the energy of the laser beam increases, and the phenomenon that the phosphor powder is destroyed due to excessive temperature or the luminous efficiency is lowered is more and more obvious.
有鑑於此,本發明之一目的在於提出一種可解決上述問題的色輪裝置。In view of the above, it is an object of the present invention to provide a color wheel device that can solve the above problems.

依據本發明之另一實施方式,一種色輪裝置應用於投影機中。色輪裝置包含殼體、色輪、馬達以及導熱元件。殼體具有至少一穿孔供光束通過。色輪設置於殼體內,並包含基板以及螢光粉層。基板具有迎光面。螢光粉層設置於迎光面上。馬達設置於殼體內,用以驅動基板轉動。在基板轉動期間,光束照射於螢光粉層上的區域為環狀被照射區域,致使殼體上形成對應於環狀被照射區域的環狀熱區。環狀熱區大體上位於光束所投射的直線位置。導熱元件實質上設置於殼體上對應於環狀熱區的位置。According to another embodiment of the present invention, a color wheel device is applied to a projector. The color wheel device includes a housing, a color wheel, a motor, and a thermally conductive element. The housing has at least one perforation for the beam to pass through. The color wheel is disposed in the housing and includes a substrate and a phosphor layer. The substrate has a light-facing surface. The phosphor layer is placed on the light-facing surface. The motor is disposed in the housing to drive the substrate to rotate. During the rotation of the substrate, the region where the light beam is irradiated onto the phosphor layer is an annular illuminated region, so that an annular hot region corresponding to the annular illuminated region is formed on the casing. The annular hot zone is generally located at a linear position projected by the beam. The thermally conductive element is disposed substantially on the housing corresponding to the location of the annular hot zone.
於本發明的一或多個實施方式中,上述的環狀熱區的面積略大於環狀被照射區域的面積。In one or more embodiments of the present invention, the area of the annular hot zone is slightly larger than the area of the annular illuminated area.
綜上所述,本發明的色輪裝置在將導熱元件設置於殼體上時,係實質上設置於光束直接照射至螢光粉層的區域(實質上對應於基板轉動時,光束的光斑於螢光粉層上所形成的區域)映射至殼體的位置進行設置。藉此,光束直接照射至螢光粉層的光斑處所產生的大量熱能即可經由基板、殼體而就近且迅速地由導熱元件導離。因此,本發明的色輪裝置可避免大量熱能蓄積在光束直接照射至螢光粉層的區域,進而可增加螢光粉層的耐受性,並間接地提升螢光粉層的發光效率。In summary, the color wheel device of the present invention is disposed substantially in a region where the light beam directly illuminates the phosphor layer when the heat conducting member is disposed on the casing (substantially corresponding to the rotation of the substrate, the spot of the light beam is The area formed on the phosphor layer is mapped to the position of the casing to be set. Thereby, a large amount of thermal energy generated by the light beam directly irradiated to the spot of the phosphor layer can be guided away from the heat conducting element by the substrate and the casing. Therefore, the color wheel device of the present invention can prevent a large amount of thermal energy from accumulating in a region where the light beam directly illuminates the phosphor powder layer, thereby increasing the resistance of the phosphor powder layer and indirectly improving the luminous efficiency of the phosphor powder layer.

以下將以圖式揭露本發明之複數個實施方式,為明確說明起見,許多實務上的細節將在以下敘述中一併說明。然而,應瞭解到,這些實務上的細節不應用以限制本發明。也就是說,在本發明部分實施方式中,這些實務上的細節是非必要的。此外,為簡化圖式起見,一些習知慣用的結構與元件在圖式中將以簡單示意的方式繪示之。The embodiments of the present invention are disclosed in the following drawings, and the details of However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not necessary. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

Fig. 1 is a rear elevational view showing a color wheel device 1 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view showing a color wheel device 1 according to an embodiment of the present invention. Fig. 3 is a front elevational view showing the color wheel 12 in Fig. 2.
如第1圖至第3圖所示,於本實施方式中,色輪裝置1可應用於投影機(圖未示)中。色輪裝置1包含殼體10、色輪12、馬達14、導熱元件16、複數個散熱鰭片18以及透鏡20。殼體10具有穿孔100供光束B(例如,雷射光束)通過。透鏡20係設置於穿孔100處。色輪12設置於殼體10內,並包含基板120以及螢光粉層122。基板120具有迎光面120a以及背光面120b。迎光面120a與背光面120b分別位於基板120的相反兩側(如第2圖中基板120的右側與左側所示)。螢光粉層122設置於迎光面120a上。馬達14設置於殼體10內,用以驅動基板120轉動。散熱鰭片18與導熱元件16熱性連接。As shown in FIGS. 1 to 3, in the present embodiment, the color wheel device 1 can be applied to a projector (not shown). The color wheel device 1 includes a housing 10, a color wheel 12, a motor 14, a heat conducting element 16, a plurality of heat sink fins 18, and a lens 20. The housing 10 has perforations 100 for the passage of a beam of light B (e.g., a laser beam). The lens 20 is disposed at the perforation 100. The color wheel 12 is disposed in the casing 10 and includes a substrate 120 and a phosphor layer 122. The substrate 120 has a light-incident surface 120a and a backlight surface 120b. The light-incident surface 120a and the backlight surface 120b are respectively located on opposite sides of the substrate 120 (as shown on the right and left sides of the substrate 120 in FIG. 2). The phosphor layer 122 is disposed on the light-facing surface 120a. The motor 14 is disposed in the housing 10 for driving the substrate 120 to rotate. The heat sink fins 18 are thermally connected to the heat conducting element 16.
舉例來說,於多個實施方式中,上述的投影機為一般的數位光處理(Digital Light Processing, DLP)投影系統,其基本架構為數位化微鏡元件(Digital Micromirror Device, DMD)搭配色輪裝置1。當光源(圖未示)所發射的光束B通過穿孔100而抵達色輪12的螢光粉層122時,會因其抵達的色區不同(因色輪12被馬達14驅動而改變),而被混光成有色光線。轉換後的有色光線大多以紅、綠、藍三色光為主。有色光線再藉由數位化微鏡元件將其反射投影至螢幕上,以形成平面影像。如第2圖所示,於本實施方式中,色輪12的基板120為反射式基板。也就是說,本實施方式的色輪裝置1為反射式色輪裝置。在光束B通過穿孔100而抵達螢光粉層122之後,被混光成的有色光線會被基板120反射而再經由穿孔100射出殼體10之外。For example, in various embodiments, the projector is a general digital light processing (DLP) projection system, and the basic structure is a digital micromirror device (DMD) with a color wheel. Device 1. When the light beam B emitted by the light source (not shown) reaches the phosphor layer 122 of the color wheel 12 through the perforation 100, it will be different due to the color region it arrives (because the color wheel 12 is driven by the motor 14 to change), It is mixed into colored light. Most of the converted colored light is mainly red, green and blue. The colored light is then projected onto the screen by a digital micromirror element to form a planar image. As shown in FIG. 2, in the present embodiment, the substrate 120 of the color wheel 12 is a reflective substrate. That is, the color wheel device 1 of the present embodiment is a reflective color wheel device. After the beam B reaches the phosphor layer 122 through the perforations 100, the colored light that is mixed is reflected by the substrate 120 and exits the casing 10 via the perforations 100.
在此先定義光束B照設於轉動之色輪12上的螢光粉層122上的區域為一環狀被照射區域Z1(如第3圖中內側的兩環狀虛線所示)。經實驗證實,在光束B長時間持續照射於螢光粉層122上的環狀被照射區域Z1會被具有能量的光束B加溫而累積大量熱能,而該些熱能則藉由熱輻射或對流的方式傳至殼體10上,致使殼體10上也形成對應於上述環狀被照射區域Z1的一環狀熱區H(如第5A圖所示)。在此須說明的是,由於環狀被照射區域Z1是以熱輻射(Radiation)或熱對流(Convection)的方式傳遞至該殼體10,因此殼體10上的環狀熱區H大體上係位於光束B所投射之一直線位置,而且環狀熱區H的面積由於殼體自身熱傳導(Conduction)的效應而會略大於環狀被照射區域Z1的面積。Here, the area defined by the light beam B on the phosphor layer 122 on the rotating color wheel 12 is an annular illuminated area Z1 (as indicated by the two circular dotted lines on the inner side in Fig. 3). It has been experimentally confirmed that the annular irradiated region Z1, which is continuously irradiated onto the phosphor layer 122 for a long time by the beam B, is heated by the beam B having energy to accumulate a large amount of thermal energy, and the thermal energy is radiated by heat or convection. The manner is transmitted to the casing 10 such that an annular hot zone H corresponding to the annular irradiated zone Z1 is formed on the casing 10 (as shown in Fig. 5A). It should be noted here that since the annular irradiated region Z1 is transmitted to the casing 10 by means of heat radiation or heat convection, the annular hot zone H on the casing 10 is substantially Located at a linear position projected by the beam B, and the area of the annular hot zone H is slightly larger than the area of the annular irradiated area Z1 due to the effect of the casing's own heat conduction.
為了將產生於色輪12上的大量熱能導離,本實施方式係將導熱元件16實質上沿著此環狀被照射區域Z1對應於殼體10的位置而設置於殼體10之外側,換言之即將導熱元件16設置於殼體10上對應於環狀熱區H的位置。藉此,螢光粉層122上的環狀被照射區域Z1所產生的大量熱能即可經由基板120、殼體10的環狀熱區H而就近且迅速地由導熱元件16傳導至散熱鰭片18,而散熱鰭片18可大面積與空氣進行熱交換,藉以再將熱量散逸至空氣中。因此,本實施方式的色輪裝置1可避免大量熱能蓄積在螢光粉層122上的環狀被照射區域Z1,進而可增加螢光粉層122的耐受性,並間接地提升螢光粉層122的發光效率。In order to guide a large amount of thermal energy generated on the color wheel 12, in the present embodiment, the heat conducting element 16 is disposed on the outer side of the casing 10 substantially along the position of the annular illuminated area Z1 corresponding to the casing 10, in other words. That is, the heat conducting element 16 is disposed on the housing 10 at a position corresponding to the annular hot zone H. Thereby, a large amount of thermal energy generated by the annular irradiated region Z1 on the phosphor layer 122 can be conducted to the heat dissipating fins by the heat conducting element 16 and rapidly and rapidly via the substrate 120 and the annular hot zone H of the casing 10. 18, and the heat dissipating fins 18 can exchange heat with air over a large area, thereby dissipating heat into the air. Therefore, the color wheel device 1 of the present embodiment can avoid a large amount of thermal energy accumulated in the annular irradiated region Z1 on the phosphor layer 122, thereby increasing the tolerance of the phosphor layer 122 and indirectly enhancing the phosphor powder. The luminous efficiency of layer 122.
從另一個角度來看,光束B於螢光粉層122上可形成光斑。在基板120轉動期間,光束B的光斑於螢光粉層122上可形成環狀路徑P(如第3圖中的中心線所示)。本實施方式係將導熱元件16實質上設置於環狀路徑P映射至殼體10的位置(如第5A圖所示)。具體來說,導熱元件16於基板120的迎光面120a上的正投影與環狀路徑P至少部分重疊(可參考第5A圖)。藉由上述所定義的環狀路徑P,即可在將導熱元件16設置至殼體10時提供明確的依據(因上述的環狀熱區H的位置大致對應於環狀路徑P的位置),並確實地達到上述就近且迅速地將色輪12上的大量熱能導離的目的。若為了達到較佳的導熱效果,於多個實施方式中,導熱元件16於基板120的迎光面120a上的正投影至少重疊環狀路徑P的一半以上。From another perspective, the beam B can form a spot on the phosphor layer 122. During the rotation of the substrate 120, the spot of the light beam B forms an annular path P on the phosphor layer 122 (as indicated by the center line in FIG. 3). In the present embodiment, the heat conducting element 16 is substantially disposed at a position where the annular path P is mapped to the casing 10 (as shown in FIG. 5A). Specifically, the orthographic projection of the thermally conductive element 16 on the light-facing surface 120a of the substrate 120 at least partially overlaps the annular path P (refer to FIG. 5A). With the annular path P defined above, a clear basis can be provided when the heat conducting element 16 is placed to the casing 10 (since the position of the annular hot zone H described above substantially corresponds to the position of the annular path P), And the purpose of guiding the large amount of thermal energy on the color wheel 12 in the vicinity and quickly is achieved. In order to achieve a better thermal conductivity, in various embodiments, the orthographic projection of the thermally conductive element 16 on the light-facing surface 120a of the substrate 120 overlaps at least half of the annular path P.
再由另一個角度來看,在基板120轉動期間,殼體10的穿孔100於基板120的迎光面120a上的正投影係在迎光面120a上形成環狀投影帶Z2(如第3圖中外側的兩環狀虛線所示)。導熱元件16於基板120的迎光面120a上的正投影與環狀投影帶Z2至少部分重疊。藉由上述所定義的環狀投影帶Z2,同樣可在將導熱元件16設置至殼體10時提供明確的依據(因上述的環狀被照射區域Z1的位置大致對應於環狀投影帶Z2的位置),並確實地達到上述就近且迅速地將色輪12上的大量熱能導離的目的。於本實施方式中,如第3圖所示,環狀被照射區域Z1的面積係略小於環狀投影帶Z2的面積,但本發明並不以此為限。於實際應用中,環狀被照射區域Z1的面積也可等於環狀投影帶Z2的面積。From another point of view, during the rotation of the substrate 120, the orthographic projection of the perforation 100 of the casing 10 on the light-facing surface 120a of the substrate 120 forms an annular projection tape Z2 on the light-facing surface 120a (as shown in FIG. 3). The two outer circular lines in the middle and outer sides are shown). The orthographic projection of the thermally conductive element 16 on the light-facing surface 120a of the substrate 120 at least partially overlaps the annular projection strip Z2. The annular projection tape Z2 defined above can also provide a clear basis for the provision of the heat-conducting element 16 to the housing 10 (since the position of the annular illuminated area Z1 substantially corresponds to the annular projection zone Z2) Position) and indeed achieve the purpose of directing and rapidly diverting a large amount of thermal energy from the color wheel 12 as described above. In the present embodiment, as shown in FIG. 3, the area of the annular irradiated region Z1 is slightly smaller than the area of the annular projection tape Z2, but the present invention is not limited thereto. In practical applications, the area of the annular illuminated area Z1 may also be equal to the area of the annular projected strip Z2.
如第2圖所示,於本實施方式中,導熱元件16位於基板120靠近背光面120b的一側,並設置於殼體10外。然而,本發明並不以此為限。請參照第4A圖至第4C圖。第4A圖為繪示第2圖中的色輪裝置1於另一實施方式中的剖面圖。第4B圖為繪示第2圖中的色輪裝置1於另一實施方式中的剖面圖。第4C圖為繪示第2圖中的色輪裝置1於另一實施方式中的剖面圖。As shown in FIG. 2, in the present embodiment, the heat transfer element 16 is located on the side of the substrate 120 close to the backlight surface 120b, and is disposed outside the casing 10. However, the invention is not limited thereto. Please refer to Figures 4A to 4C. Fig. 4A is a cross-sectional view showing the color wheel device 1 of Fig. 2 in another embodiment. Fig. 4B is a cross-sectional view showing the color wheel device 1 in Fig. 2 in another embodiment. Fig. 4C is a cross-sectional view showing the color wheel device 1 of Fig. 2 in another embodiment.
如第4A圖所示,導熱元件16位於基板120靠近迎光面120a的一側,並設置於殼體10外。如第4B圖所示,導熱元件16位於基板120靠近背光面120b的一側,並設置於殼體10內。如第4C圖所示,導熱元件16位於基板120靠近迎光面120a的一側,並設置於殼體10內。在第2圖與第4A圖的實施方式中,由於導熱元件16係設置於殼體10外,因此導熱元件16的一端可直接延伸連接至散熱鰭片18。在第4B圖與第4C圖的實施方式中,由於導熱元件16係設置於殼體10內,因此導熱元件16的一端必須先穿出殼體10,再延伸連接至散熱鰭片18。此外,在第4A圖的實施方式中,導熱元件16設置於殼體10外時還需繞過透鏡20位置。As shown in FIG. 4A, the heat conducting element 16 is located on the side of the substrate 120 adjacent to the light-incident surface 120a and disposed outside the casing 10. As shown in FIG. 4B, the heat conducting element 16 is located on the side of the substrate 120 adjacent to the backlight surface 120b and is disposed in the housing 10. As shown in FIG. 4C, the heat conducting element 16 is located on the side of the substrate 120 adjacent to the light-incident surface 120a, and is disposed in the casing 10. In the embodiments of FIGS. 2 and 4A, since the heat conducting element 16 is disposed outside the housing 10, one end of the heat conducting element 16 may be directly extended to the heat sink fins 18. In the embodiments of FIGS. 4B and 4C, since the heat conducting element 16 is disposed in the housing 10, one end of the heat conducting element 16 must first pass out of the housing 10 and then extend to the heat sink fins 18. Furthermore, in the embodiment of FIG. 4A, the position of the lens 20 is also required to be bypassed when the heat conducting element 16 is disposed outside of the housing 10.
在上述的各實施方式中,雖然導熱元件16設置於殼體10的位置不盡相同,但只要符合使導熱元件16沿著上述定義的環狀路徑P設置於殼體10的原則(即,使導熱元件16於迎光面120a上的正投影盡可能與上述定義的環狀路徑P、環狀被照射區域Z1、環狀投影帶Z2或環狀熱區H重疊),就可達到就近且迅速地將色輪12上的大量熱能導離的目的。在其他的實施態樣,本領域的人也可根據實際需求使兩道以上的光束B分別由兩個以上的穿孔100進入殼體10而照射在色輪12上,此實施態樣同樣使用上述原則也能有效的將熱能移除。In each of the above embodiments, although the position of the heat-conducting element 16 disposed in the casing 10 is not the same, it is only required to conform to the principle that the heat-conducting element 16 is disposed on the casing 10 along the above-defined annular path P (ie, The orthographic projection of the heat conducting element 16 on the light-incident surface 120a is as close as possible to the annular path P, the annular illuminated area Z1, the annular projected strip Z2 or the annular hot zone H defined above, so that the near and rapid can be achieved. The purpose of guiding a large amount of thermal energy on the color wheel 12 is grounded. In other embodiments, one skilled in the art can also illuminate the color wheel 12 by inserting two or more light beams B into the housing 10 from two or more perforations 100 according to actual needs.

請參照第5A圖,其為繪示第1圖中的導熱元件16的示意圖。於本實施方式中,色輪裝置1共包含四個導熱元件16,其中外圍的兩導熱元件16與環狀路徑P及環狀熱區H重疊,而內側的兩導熱元件16實質上沿著環狀熱區H的內緣設置。雖然內側的兩導熱元件16並未與環狀路徑P及環狀熱區H重疊,但也可達到輔助散熱的效果。然而,本發明並不以此為限。請參照第5B圖以及第5C圖。第5B圖為繪示第1圖中的導熱元件16於另一實施方式中的示意圖。第5C圖為繪示第1圖中的導熱元件16於另一實施方式中的示意圖。Please refer to FIG. 5A , which is a schematic diagram showing the heat conducting element 16 in FIG. 1 . In the present embodiment, the color wheel device 1 comprises a total of four heat conducting elements 16, wherein the outer two heat conducting elements 16 overlap the annular path P and the annular hot zone H, while the inner two heat conducting elements 16 substantially follow the ring. The inner edge of the hot zone H is set. Although the inner two heat conducting elements 16 do not overlap the annular path P and the annular hot zone H, the effect of assisting heat dissipation can be achieved. However, the invention is not limited thereto. Please refer to Figure 5B and Figure 5C. FIG. 5B is a schematic view showing the heat conducting element 16 in FIG. 1 in another embodiment. FIG. 5C is a schematic view showing the heat conducting element 16 in FIG. 1 in another embodiment.
如第5B圖所示,於本實施方式中,色輪裝置1同樣包含四個導熱元件16,其中外圍的兩導熱元件16與環狀路徑P及環狀熱區H重疊,而內側的兩導熱元件16實質上沿著環狀熱區H的內緣設置。要說明的是,相較於第5A圖所示的實施方式,本實施方式的導熱元件16於迎光面120a上的正投影與環狀路徑P及環狀熱區H重疊的比例更多,因此可增加總導熱量。As shown in FIG. 5B, in the present embodiment, the color wheel device 1 also includes four heat conducting elements 16, wherein the outer two heat conducting elements 16 overlap the annular path P and the annular hot zone H, and the inner two heat conducting. Element 16 is disposed substantially along the inner edge of annular hot zone H. It should be noted that, compared with the embodiment shown in FIG. 5A, the ratio of the orthographic projection of the heat conducting element 16 of the present embodiment on the light-incident surface 120a overlaps the annular path P and the annular hot zone H, Therefore, the total amount of heat conduction can be increased.
若僅為了達到本發明欲就近且迅速地將色輪12上的大量熱能導離的目的,色輪裝置1可以僅包含兩個導熱元件16,如第5C圖所示。於本實施方式中,中每一導熱元件16於迎光面120a上的正投影各與環狀路徑P重疊接近一半。更甚者,於其他實施方式中,色輪裝置1可以僅包含單一導熱元件16,且此導熱元件16於迎光面120a上的正投影與環狀路徑P重疊至少一半以上。The color wheel device 1 may only include two heat conducting elements 16 for the purpose of achieving the purpose of directing and rapidly directing a large amount of thermal energy on the color wheel 12, as shown in Fig. 5C. In the present embodiment, the orthographic projections of each of the heat conducting elements 16 on the light-incident surface 120a overlap with the annular path P by nearly half. Moreover, in other embodiments, the color wheel device 1 may include only a single heat conducting element 16, and the orthographic projection of the heat conducting element 16 on the light-facing surface 120a overlaps the annular path P by at least half.
於多個實施方式中,導熱元件16為熱管或冷卻流體管路,但本發明並不以此為限。於多個實施方式中,導熱元件16可以貼附或嵌合的方式固定至殼體10,但本發明並不以此為限。In various embodiments, the heat conducting element 16 is a heat pipe or a cooling fluid line, but the invention is not limited thereto. In various embodiments, the thermally conductive element 16 can be attached to the housing 10 in a manner that is attached or mated, but the invention is not limited thereto.
請參照第6圖以及第7A圖。第6圖為繪示本發明一實施方式的色輪裝置3的正視圖。第7A圖為繪示本發明一實施方式的色輪裝置3的剖面圖。Please refer to Figure 6 and Figure 7A. Fig. 6 is a front elevational view showing the color wheel device 3 according to an embodiment of the present invention. Fig. 7A is a cross-sectional view showing the color wheel device 3 according to an embodiment of the present invention.
如第6圖與第7A圖所示,於本實施方式中,色輪裝置3同樣可應用於投影機(圖未示)中。色輪裝置3包含殼體30、色輪32、馬達14、導熱元件16、複數個散熱鰭片18以及兩透鏡40a,40b。殼體30具有兩穿孔300a,300b供光束B(例如,雷射光束)通過。兩透鏡40a,40b係分別設置於穿孔300a, 300b處。色輪32設置於殼體30內,並包含基板320以及螢光粉層122。兩穿孔300a,300b係隔著基板320相互對齊。基板320具有迎光面320a以及背光面320b。迎光面320a與背光面320b分別位於基板320的相反兩側(如第7A圖中基板320的左側與右側所示)。螢光粉層122設置於迎光面320a上。馬達14設置於殼體30內,用以驅動基板320轉動。散熱鰭片18與導熱元件16熱性連接。在其他多道光束的實施態樣中,則可使每道光束B依上述原則設置穿孔,例如兩道光束B則設置有四個穿孔位於殼體30兩側,也就是說穿孔的數目為二的倍數。As shown in Fig. 6 and Fig. 7A, in the present embodiment, the color wheel device 3 is similarly applicable to a projector (not shown). The color wheel device 3 includes a housing 30, a color wheel 32, a motor 14, a heat conducting element 16, a plurality of heat sink fins 18, and two lenses 40a, 40b. The housing 30 has two perforations 300a, 300b through which a beam B (e.g., a laser beam) passes. The two lenses 40a, 40b are respectively disposed at the perforations 300a, 300b. The color wheel 32 is disposed in the housing 30 and includes a substrate 320 and a phosphor layer 122. The two through holes 300a, 300b are aligned with each other across the substrate 320. The substrate 320 has a light-incident surface 320a and a backlight surface 320b. The light-facing surface 320a and the backlight surface 320b are respectively located on opposite sides of the substrate 320 (as shown on the left and right sides of the substrate 320 in FIG. 7A). The phosphor layer 122 is disposed on the light-facing surface 320a. The motor 14 is disposed in the housing 30 for driving the substrate 320 to rotate. The heat sink fins 18 are thermally connected to the heat conducting element 16. In the embodiment of the other multi-beams, each of the beams B can be perforated according to the above principle. For example, the two beams B are provided with four perforations on both sides of the casing 30, that is, the number of perforations is two. Multiples.
如第7A圖所示,於本實施方式中,色輪32的基板320為穿透式基板。也就是說,本實施方式的色輪裝置3為穿透式色輪裝置。在光束B通過穿孔300a而抵達基板320之後,會繼續穿過基板320而抵達螢光粉層122並被混光成有色光線,接著再經由穿孔300b射出殼體30之外。As shown in FIG. 7A, in the present embodiment, the substrate 320 of the color wheel 32 is a transmissive substrate. That is, the color wheel device 3 of the present embodiment is a transmissive color wheel device. After the light beam B reaches the substrate 320 through the through hole 300a, it continues to pass through the substrate 320 to reach the phosphor layer 122 and is mixed into colored light, and then exits the casing 30 via the through hole 300b.
為了將產生於色輪32上的大量熱能導離,本實施方式係同樣將導熱元件16實質上沿著螢光粉層122上的環狀被照射區域對應於殼體30的位置而設置於殼體30上之外側,換言之即將導熱元件16設置於殼體30上對應於環狀熱區H的位置(可參考第8A圖)。藉此,螢光粉層122上的環狀被照射區域Z1所產生的大量熱能即可經由基板320、殼體30的環狀熱區H而就近且迅速地由導熱元件16傳導至散熱鰭片18。因此,本實施方式的色輪裝置3同樣可避免大量熱能蓄積在螢光粉層122上的環狀被照射區域Z1,進而可增加螢光粉層122的耐受性,並間接地提升螢光粉層122的發光效率。In order to conduct a large amount of thermal energy generated on the color wheel 32, the present embodiment also places the heat conducting element 16 substantially in the shell along the annular illuminated area on the phosphor layer 122 corresponding to the position of the housing 30. The outer side of the body 30, in other words, the heat conducting element 16 is disposed on the housing 30 corresponding to the position of the annular hot zone H (refer to Fig. 8A). Thereby, a large amount of thermal energy generated by the annular irradiated region Z1 on the phosphor layer 122 can be conducted to the heat dissipating fins by the heat conducting element 16 and rapidly and rapidly via the substrate 320 and the annular hot zone H of the casing 30. 18. Therefore, the color wheel device 3 of the present embodiment can also avoid a large amount of thermal energy accumulated in the annular irradiated region Z1 on the phosphor layer 122, thereby increasing the tolerance of the phosphor layer 122 and indirectly enhancing the fluorescence. The luminous efficiency of the powder layer 122.
從另一個角度來看,光束B於螢光粉層122上可形成光斑。在基板320轉動期間,光束B的光斑於螢光粉層122上可形成環狀路徑P(可參考第3圖中的中心線)。本實施方式係將導熱元件16實質上設置於環狀路徑P映射至殼體30的位置(如第8A圖所示)。具體來說,導熱元件16於基板320的迎光面320a上的正投影與環狀路徑P至少部分重疊(可參考第8A圖)。藉由上述所定義的環狀路徑P,即可在將導熱元件16設置至殼體30時提供明確的依據(因上述的環狀熱區H的位置大致對應於環狀路徑P的位置),並確實地達到上述就近且迅速地將色輪32上的大量熱能導離的目的。若為了達到較佳的導熱效果,於多個實施方式中,導熱元件16於基板320的迎光面320a上的正投影至少重疊環狀路徑P的一半以上。From another perspective, the beam B can form a spot on the phosphor layer 122. During the rotation of the substrate 320, the spot of the light beam B forms an annular path P on the phosphor layer 122 (refer to the center line in FIG. 3). In the present embodiment, the heat conducting element 16 is substantially disposed at a position where the annular path P is mapped to the casing 30 (as shown in FIG. 8A). Specifically, the orthographic projection of the thermally conductive element 16 on the light-facing surface 320a of the substrate 320 at least partially overlaps the annular path P (refer to FIG. 8A). With the annular path P defined above, a clear basis can be provided when the heat conducting element 16 is placed to the housing 30 (since the position of the annular hot zone H described above substantially corresponds to the position of the annular path P), And the purpose of guiding the large amount of thermal energy on the color wheel 32 in the vicinity and quickly is achieved. In order to achieve a better thermal conductivity, in various embodiments, the orthographic projection of the thermally conductive element 16 on the light-facing surface 320a of the substrate 320 overlaps at least half of the annular path P.
再由另一個角度來看,在基板320轉動期間,殼體30的穿孔300a於基板320的迎光面320a上的正投影係在迎光面320a上形成環狀投影帶Z2(可參考第3圖中外側的兩環狀虛線)。導熱元件16於基板320的迎光面320a上的正投影與環狀投影帶Z2至少部分重疊。藉由上述所定義的環狀投影帶Z2,同樣可在將導熱元件16設置至殼體30時提供明確的依據(因上述的環狀被照射區域Z1的位置大致對應於環狀投影帶Z2的位置),並確實地達到上述就近且迅速地將色輪32上的大量熱能導離的目的。From another point of view, during the rotation of the substrate 320, the orthographic projection of the through hole 300a of the casing 30 on the light-incident surface 320a of the substrate 320 forms an annular projection tape Z2 on the light-facing surface 320a (refer to the third Two circular dotted lines on the outside in the figure). The orthographic projection of the thermally conductive element 16 on the mating surface 320a of the substrate 320 at least partially overlaps the annular projection strip Z2. The annular projection tape Z2 defined above can also provide a clear basis for providing the heat conducting element 16 to the housing 30 (since the position of the annular illuminated area Z1 substantially corresponds to the annular projection band Z2) Position) and indeed achieve the purpose of directing and rapidly diverting a large amount of thermal energy from the color wheel 32 as described above.
如第7A圖所示,於本實施方式中,導熱元件16位於基板320靠近背光面320b的一側,並設置於殼體30外。然而,本發明並不以此為限。請參照第7B圖至第7D圖。第7B圖為繪示第7A圖中的色輪裝置3於另一實施方式中的剖面圖。第7C圖為繪示第7A圖中的色輪裝置3於另一實施方式中的剖面圖。第7D圖為繪示第7A圖中的色輪裝置3於另一實施方式中的剖面圖。As shown in FIG. 7A, in the present embodiment, the heat conduction element 16 is located on the side of the substrate 320 close to the backlight surface 320b, and is disposed outside the casing 30. However, the invention is not limited thereto. Please refer to Figures 7B to 7D. Fig. 7B is a cross-sectional view showing the color wheel device 3 in Fig. 7A in another embodiment. Figure 7C is a cross-sectional view showing the color wheel device 3 of Figure 7A in another embodiment. Fig. 7D is a cross-sectional view showing the color wheel device 3 in Fig. 7A in another embodiment.
如第7B圖所示,導熱元件16位於基板320靠近迎光面320a的一側,並設置於殼體30外。如第7C圖所示,導熱元件16位於基板320靠近背光面320b的一側,並設置於殼體30內。如第7D圖所示,導熱元件16位於基板320靠近迎光面320a的一側,並設置於殼體30內。在第7A圖與第7B圖的實施方式中,由於導熱元件16係設置於殼體30外,因此導熱元件16的一端可直接延伸連接至散熱鰭片18。在第7C圖與第7D圖的實施方式中,由於導熱元件16係設置於殼體30內,因此導熱元件16的一端必須先穿出殼體30,再延伸連接至散熱鰭片18。此外,在第7A圖的實施方式中,導熱元件16設置於殼體30外時還需繞過透鏡40a,而在第7B圖的實施方式中,導熱元件16設置於殼體30外時還需繞過透鏡40b。As shown in FIG. 7B, the heat conducting element 16 is located on the side of the substrate 320 near the light-incident surface 320a and is disposed outside the casing 30. As shown in FIG. 7C, the heat conducting element 16 is located on the side of the substrate 320 near the backlight surface 320b and is disposed in the housing 30. As shown in FIG. 7D, the heat conducting element 16 is located on the side of the substrate 320 adjacent to the light-incident surface 320a and is disposed in the housing 30. In the embodiments of FIGS. 7A and 7B, since the heat conducting element 16 is disposed outside the housing 30, one end of the heat conducting element 16 may be directly extended to the heat sink fins 18. In the embodiments of FIGS. 7C and 7D, since the heat conducting element 16 is disposed in the housing 30, one end of the heat conducting element 16 must first pass out of the housing 30 and then extend to the heat sink fins 18. In addition, in the embodiment of FIG. 7A, the heat-conducting element 16 needs to be disposed outside the casing 30 to bypass the lens 40a, and in the embodiment of FIG. 7B, the heat-conducting element 16 is required to be disposed outside the casing 30. The lens 40b is bypassed.
在上述的各實施方式中,雖然導熱元件16設置於殼體30的位置不盡相同,但只要符合使導熱元件16沿著上述定義的環狀路徑P設置於殼體30的原則(即,使導熱元件16於迎光面320a上的正投影盡可能與上述定義的環狀路徑P、環狀被照射區域Z1、環狀投影帶Z2或環狀熱區H重疊),就可達到就近且迅速地將色輪32上的大量熱能導離的目的。In each of the above embodiments, although the position of the heat-conducting element 16 disposed in the casing 30 is not the same, it is only required to conform to the principle that the heat-conducting element 16 is disposed on the casing 30 along the above-defined annular path P (ie, The orthographic projection of the heat conducting element 16 on the light-facing surface 320a is as close as possible to the annular path P, the annular illuminated area Z1, the annular projected strip Z2 or the annular hot zone H defined above, so that the near and rapid can be achieved. The purpose of guiding a large amount of thermal energy on the color wheel 32 is grounded.
請參照第8A圖,其為繪示第6圖中的導熱元件16的示意圖。於本實施方式中,色輪裝置3共包含四個導熱元件16,其中外圍的兩導熱元件16與環狀路徑P及環狀熱區H重疊,並繞過透鏡40a(於第8A圖中以虛線表示),而內側的兩導熱元件16實質上沿著環狀熱區H的內緣設置。雖然內側的兩導熱元件16並未與環狀路徑P及環狀熱區H重疊,但也可達到輔助散熱的效果。然而,本發明並不以此為限。請參照第8B圖以及第8C圖。第8B圖為繪示第6圖中的導熱元件16於另一實施方式中的示意圖。第8C圖為繪示第6圖中的導熱元件16於另一實施方式中的示意圖。Please refer to FIG. 8A, which is a schematic diagram showing the heat conducting element 16 in FIG. In the present embodiment, the color wheel device 3 comprises a total of four heat conducting elements 16, wherein the outer two heat conducting elements 16 overlap the annular path P and the annular hot zone H and bypass the lens 40a (in FIG. 8A The dashed lines are shown, while the inner two thermally conductive elements 16 are disposed substantially along the inner edge of the annular hot zone H. Although the inner two heat conducting elements 16 do not overlap the annular path P and the annular hot zone H, the effect of assisting heat dissipation can be achieved. However, the invention is not limited thereto. Please refer to FIG. 8B and FIG. 8C. FIG. 8B is a schematic view showing the thermally conductive element 16 in FIG. 6 in another embodiment. FIG. 8C is a schematic view showing the heat conducting element 16 in FIG. 6 in another embodiment.
如第8B圖與第8C圖所示,若僅為了達到本發明欲就近且迅速地將色輪32上的大量熱能導離的目的,色輪裝置3可以僅包含單一導熱元件16,且導熱元件16於迎光面320a上的正投影與環狀路徑P重疊至少一半以上,並繞過透鏡40a(於第8B圖與第8C圖中以虛線表示)。要說明的是,第8B圖中的導熱元件16的兩端的延伸方向相反,而第8C圖的導熱元件16的兩端的延伸方向相同。因此,若投影機內部在殼體30的兩邊皆有足夠空間可容置散熱鰭片18,則可採用第8B圖中的導熱元件16的設計;若投影機內部僅在殼體30的某一邊有足夠空間可容置散熱鰭片18,則可採用第8C圖中的導熱元件16的設計。As shown in FIGS. 8B and 8C, the color wheel device 3 may include only a single thermally conductive element 16 and the thermally conductive element for the purpose of achieving the near and rapid derivation of a large amount of thermal energy on the color wheel 32. The orthographic projection on the light-incident surface 320a overlaps the annular path P by at least half or more, and bypasses the lens 40a (indicated by broken lines in FIGS. 8B and 8C). It is to be noted that the extending directions of both ends of the heat conducting member 16 in Fig. 8B are opposite, and the extending directions of both ends of the heat conducting member 16 of Fig. 8C are the same. Therefore, if the inside of the projector has enough space on both sides of the casing 30 to accommodate the heat dissipation fins 18, the design of the heat conduction element 16 in FIG. 8B can be adopted; if the inside of the projector is only on one side of the casing 30 If there is enough space to accommodate the heat sink fins 18, then the design of the heat conducting element 16 in Figure 8C can be employed.
由以上對於本發明之具體實施方式之詳述,可以明顯地看出,本發明的色輪裝置在將導熱元件設置於殼體上時,係實質上設置於光束直接照射至螢光粉層的區域(實質上對應於基板轉動時,光束的光斑於螢光粉層上所形成的區域)映射至殼體的位置進行設置。藉此,光束直接照射至螢光粉層的光斑處所產生的大量熱能即可經由基板、殼體而就近且迅速地由導熱元件導離。因此,本發明的色輪裝置可避免大量熱能蓄積在光束直接照射至螢光粉層的區域,進而可增加螢光粉層的耐受性,並間接地提升螢光粉層的發光效率。From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that the color wheel device of the present invention is substantially disposed on the light beam directly irradiated to the phosphor layer when the heat conducting member is disposed on the casing. The region (substantially corresponding to the region where the spot of the light beam is formed on the phosphor layer when the substrate is rotated) is mapped to the position of the casing. Thereby, a large amount of thermal energy generated by the light beam directly irradiated to the spot of the phosphor layer can be guided away from the heat conducting element by the substrate and the casing. Therefore, the color wheel device of the present invention can prevent a large amount of thermal energy from accumulating in a region where the light beam directly illuminates the phosphor powder layer, thereby increasing the resistance of the phosphor powder layer and indirectly improving the luminous efficiency of the phosphor powder layer.
