近年來，光學投影機已經被應用於許多領域之中，且應用範圍也日漸擴大，例如從消費性產品到高科技設備。各種的光學投影機也被廣泛應用於學校、家庭和商業場合，以將信號源所提供的顯示圖案放大，並顯示在投影屏幕上。In recent years, optical projectors have been used in many fields, and the range of applications is expanding day by day, from consumer products to high-tech equipment.

為了達到上述目的，依據本揭露之一實施方式，一種光源模組包含光源、螢光環、反射器、驅動裝置以及分色鏡。光源配置以沿第一方向發射激發光。螢光環具有內側面且內側面與第一方向平行。反射器設置於螢光環中央並相對於第一方向傾斜設置。反射器配置以在第一方向上反射激發光，並使激發光沿第二方向於內側面上形成第一光點。驅動裝置配置以轉動反射器，致使第一光點於內側面上沿著環狀路徑移動。分色鏡相對於第一方向傾斜設置，並配置以透射激發光並且反射受激發光。第一光點用以激發螢光環而轉化為受激發光。受激發光可經由反射器反射後抵達分色鏡，而後再經由分色鏡反射而離開光源模組。To achieve the above object, according to an embodiment of the present disclosure, a light source module includes a light source, a fluorescent ring, a reflector, a driving device, and a dichroic mirror. The light source is configured to emit excitation light in a first direction. The fluorescent ring has an inner surface and the inner surface is parallel to the first direction. The reflector is arranged in the center of the fluorescent ring and is arranged obliquely relative to the first direction. The reflector is configured to reflect the excitation light in the first direction, and make the excitation light form a first spot on the inner side along the second direction. The driving device is configured to rotate the reflector, causing the first light spot to move along a circular path on the inner side. The dichroic mirror is disposed obliquely with respect to the first direction and is configured to transmit excitation light and reflect excitation light. The first light spot is used to excite the fluorescent ring to convert into excited light. The excited light can be reflected by the reflector and reach the dichroic mirror, and then be reflected by the dichroic mirror and leave the light source module.

於本揭露的一或多個實施方式中，光源模組進一步包含另一分色鏡。此另一分色鏡相對於第一方向傾斜設置，並位於螢光環中央且靠近反射器。此另一分色鏡配置以將一部分之激發光反射至內側面以形成第二光點，並透射另一部分之激發光至反射器而形成第一光點。驅動裝置配置以同時轉動此另一分色鏡及反射器，致使第一光點與第二光點於內側面的不同位置同時沿著不同環狀路徑移動。In one or more embodiments of the present disclosure, the light source module further includes another dichroic mirror. The other dichroic mirror is arranged obliquely relative to the first direction, and is located in the center of the fluorescent ring and close to the reflector. The other dichroic mirror is configured to reflect a part of the excitation light to the inner surface to form the second light spot, and transmit another part of the excitation light to the reflector to form the first light spot. The driving device is configured to simultaneously rotate the other dichroic mirror and the reflector, so that the first light spot and the second light spot move along different circular paths at different positions on the inner surface.

於本揭露的一或多個實施方式中，螢光環具有分別對應第一光點及第二光點的兩圈螢光區塊。此兩圈螢光區塊配置以將激發光分別轉換為不同色光後，經分色鏡反射而離開光源模組。In one or more implementations of the present disclosure, the fluorescent ring has two circles of fluorescent blocks respectively corresponding to the first light spot and the second light spot. The two circles of fluorescent blocks are configured to convert the excitation light into different colors of light, and then reflect off the dichroic mirror and leave the light source module.

綜上所述，於本揭露的光源模組中，藉由轉動的反射器將光源所產生的光沿著環狀路徑投射到固定不動的螢光環的內側面，即可利用螢光環的螢光區塊產生不同色光，且色光可再依序經由反射器及其他光學元件導引至投影機的光學引擎。由於螢光環是固定不動的，因此螢光環可彈性地擴充與其熱性連接之散熱結構（例如散熱鰭片、散熱器、熱導管、水冷系統等），且光源在螢光區塊上所產生的熱能可比習知轉動式的螢光輪更快地導離。藉此，本揭露的光源模組可輕易地採用更高功率的光源。不僅如此，轉動的反射器可完全在部分由螢光環構成之殼體的密閉空間內作動，因此可有效隔離空氣粉塵，從而避免反射器及螢光區塊的表面受污染而影響激發效率。To sum up, in the light source module of the present disclosure, the light generated by the light source is projected onto the inner surface of the fixed fluorescent ring along the circular path by the rotating reflector, so that the fluorescent light of the fluorescent ring can be utilized. The blocks generate different colored light, and the colored light can be guided to the optical engine of the projector through reflectors and other optical components in sequence. Since the fluorescent ring is fixed, the fluorescent ring can flexibly expand the heat dissipation structure connected to it (such as cooling fins, radiators, heat pipes, water cooling systems, etc.), and the heat generated by the light source on the fluorescent block It can lead off faster than the conventional rotating fluorescent wheel. Therefore, the light source module of the present disclosure can easily adopt a higher power light source. Not only that, the rotating reflector can operate completely in the enclosed space of the casing partially formed by the fluorescent ring, so it can effectively isolate air dust, thereby preventing the surface of the reflector and fluorescent block from being polluted and affecting the excitation efficiency.

以上所述僅係用以闡述本揭露所欲解決的問題、解決問題的技術手段、及其產生的功效等等，本揭露之具體細節將在下文的實施方式及相關圖式中詳細介紹。The above description is only used to explain the problems to be solved by the present disclosure, the technical means to solve the problems, and the effects thereof, etc. The specific details of the present disclosure will be introduced in detail in the following implementation methods and related drawings.

於一些實施方式中，環形散熱器252與平台251可相互組合而構成覆蓋環本體231的下開口的底座250。於一些實施方式中，底座250為單體結構（亦即環形散熱器252與平台251係一體成形）。In some embodiments, the annular radiator 252 and the platform 251 can be combined to form the base 250 covering the lower opening of the ring body 231 . In some embodiments, the base 250 is a single structure (that is, the annular heat sink 252 and the platform 251 are integrally formed).

於一些實施方式中，螢光環230的環本體231、環形散熱器252與平台251中的至少一者的材料包含金屬，但本揭露並不以此為限。In some embodiments, the material of at least one of the ring body 231 , the annular radiator 252 and the platform 251 of the fluorescent ring 230 includes metal, but the present disclosure is not limited thereto.

在前述結構配置下，由於螢光環230是固定不動的，因此螢光環230可彈性地擴充與其熱性連接之散熱結構（例如散熱鰭片、散熱器、熱導管、水冷系統等），且光源210在螢光區塊232上所產生的熱能可比習知轉動式的螢光輪更快地導離。Under the aforementioned structural configuration, since the fluorescent ring 230 is fixed, the fluorescent ring 230 can flexibly expand the heat dissipation structure (such as heat dissipation fins, radiators, heat pipes, water cooling systems, etc.) thermally connected to it, and the light source 210 The heat energy generated on the fluorescent block 232 can be dissipated faster than the conventional rotating fluorescent wheel.

The light guide assembly 220' includes a tube 221', a dichroic mirror 213c, and a plurality of lenses 223'. The light guide component 220' is located inside the inner surface of the fluorescent ring 230', and is fixed on the side of the light guide component 220 away from the rotating shaft 242. The dichroic mirror 213c is obliquely disposed in the tube 221' with respect to the first direction A1, and is located in the center of the fluorescent ring 230' and close to the reflector 222. The lenses 223' are arranged and disposed at one end of the tube 221'. The motor 241 can simultaneously rotate the light guide components 220, 220' via the rotating shaft 242. The dichroic mirror 213c disposed in the tube 221' can be inclined at an angle of 45 degrees relative to the rotation axis of the rotating shaft 242, so as to horizontally reflect a part of the excitation light incident vertically from above to the inner surface of the fluorescent ring 230', and allow the excitation The other part of the light passes to the reflector 222 below (ie, the dichroic mirror 213c is optically coupled between the light source 210 and the reflector 222 ). The excitation light reflected by the dichroic mirror 213c will form another light spot P' on the inner surface of the fluorescent ring 230', and the rotated light guide component 220' will make this light spot P' along the other side on the inner surface. Circular path movement. At this time, the light source module 200' will form two light spots P, P' at different height positions on the inner surface of the fluorescent ring 230' while moving along the circular path.

另外，螢光環230’進一步複數個螢光區塊232’。螢光區塊232’沿著前述另一環狀路徑排列於環本體231’的內緣。換言之，本實施方式之螢光環230’具有上下兩圈螢光區塊232、232’。螢光區塊232’配置以將由分色鏡213c水平反射而來的激發光分別轉換為不同色光。色光可再沿著原光路被分色鏡213c反射而由環本體231’的上開口離開。由環本體231’的上開口離開的色光會被分色鏡213a反射，並依序通過分色鏡213b、聚光透鏡212c、顏色調整輪215以及積分柱216，最後抵達光學引擎300。In addition, the fluorescent ring 230' further has a plurality of fluorescent blocks 232'. The fluorescent blocks 232' are arranged on the inner edge of the ring body 231' along the aforementioned another ring path. In other words, the fluorescent ring 230' of this embodiment has two upper and lower circles of fluorescent blocks 232, 232'. The fluorescent block 232' is configured to convert the excitation light horizontally reflected by the dichroic mirror 213c into different colored light respectively. The colored light can then be reflected by the dichroic mirror 213c along the original optical path and exit through the upper opening of the ring body 231'. The colored light exiting from the upper opening of the ring body 231' will be reflected by the dichroic mirror 213a, and pass through the dichroic mirror 213b, the condenser lens 212c, the color adjustment wheel 215 and the integrating column 216 in sequence, and finally arrive at the optical engine 300.

如第4圖所示，於本實施方式中，光點P、P’分別位於螢光環230’的相反兩側。藉此，即可將光源210在螢光環230’上所產生的熱能更均勻地分散。As shown in FIG. 4, in this embodiment, the light spots P and P' are respectively located on opposite sides of the fluorescent ring 230'. Thereby, the heat energy generated by the light source 210 on the fluorescent ring 230' can be more evenly distributed.

相較於第1圖所示之實施方式，本實施方式之螢光環230’取消了透光鏡233，環本體231’不具有透光部231a，且對應之聚光透鏡212d與全反射鏡214亦取消。另外，本實施方式之光源模組200進一步包含另一風扇271。兩風扇270、271分別位於螢光環230’的相反兩側，並可產生氣流以將散熱鰭片234上的熱快速帶走。Compared with the embodiment shown in FIG. 1, the fluorescent ring 230' of this embodiment cancels the light-transmitting mirror 233, the ring body 231' does not have the light-transmitting part 231a, and the corresponding condenser lens 212d and the total reflection mirror 214 also canceled. In addition, the light source module 200 of this embodiment further includes another fan 271 . The two fans 270, 271 are respectively located on opposite sides of the fluorescent ring 230', and can generate airflow to quickly remove the heat on the cooling fins 234.

由以上對於本揭露之具體實施方式之詳述，可以明顯地看出，於本揭露的光源模組中，藉由轉動的反射器將光源所產生的光沿著環狀路徑投射到固定不動的螢光環的內側面，即可利用螢光環的螢光區塊產生不同色光，且色光可再依序經由反射器及其他光學元件導引至投影機的光學引擎。由於螢光環是固定不動的，因此螢光環可彈性地擴充與其熱性連接之散熱結構（例如散熱鰭片、散熱器、熱導管、水冷系統等），且光源在螢光區塊上所產生的熱能可比習知轉動式的螢光輪更快地導離。藉此，本揭露的光源模組可輕易地採用更高功率的光源。不僅如此，轉動的反射器可完全在部分由螢光環構成之殼體的密閉空間內作動，因此可有效隔離空氣粉塵，從而避免反射器及螢光區塊的表面受污染而影響激發效率。From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the light source module of the present disclosure, the light generated by the light source is projected along the circular path to the fixed The inner surface of the fluorescent ring can use the fluorescent blocks of the fluorescent ring to generate different colors of light, and the colored lights can be guided to the optical engine of the projector through the reflector and other optical components in sequence. Since the fluorescent ring is fixed, the fluorescent ring can flexibly expand the heat dissipation structure connected to it (such as cooling fins, radiators, heat pipes, water cooling systems, etc.), and the heat generated by the light source on the fluorescent block It can lead off faster than the conventional rotating fluorescent wheel. Therefore, the light source module of the present disclosure can easily adopt a higher power light source. Not only that, the rotating reflector can operate completely in the enclosed space of the casing partially formed by the fluorescent ring, so it can effectively isolate air dust, thereby preventing the surface of the reflector and fluorescent block from being polluted and affecting the excitation efficiency.
