先前技術 在目前的市場上,投影機因所使用之顯示技術的不同 而可分為四類·· CRT (Cathode Ray Tube)投影機、LCD (Liquid Crystal Display)投影機、DLp (DigitalPrevious technologies In the current market, projectors can be divided into four categories depending on the display technology used.

燈或氙氣燈等發光,經集光至面板以將面板的影像經反射 或透射投射出影像,再經過分光、合光系統,最後將影像 投射到屏幕顯像。而其中DLP投影機之關鍵性技術為利用 一種由二位元脈衝調變控制的半導體元件D〇 ( Digi tal Micromiirror Device,數位微鏡元件)來作為反射裝置並 進以可投射圖像到螢幕。其中DMD能很快速且具反射性的 控制數位光學開關之外,亦能準確的控制光源。又每個 DMD晶片包含成千上萬微小的正方形反射鏡片(微鏡)。 由光源(1 ight )發射的光經交替投射到D〇表面後,DMD 晶片上的所有微鏡,根據自身對應的圖元中各顏色(紅或 綠或監)的數量’決定了其對該色光處於開位置的次數, 也即決定了反射後通過投影鏡頭投射到螢幕上的光數量。 由於D M D具有反射性及焉填滿率的特性,可產生較高的 光學效率’因此DLP投影機非常適用於需要高亮度及高 解像度的用途。較佳的散熱性,也使得DLp投影機可以 使用高瓦數的光源,而不會減低DMD的壽命;同時DLP 的全數位化設計’也提供了更為正確並穩定的再生影像。 目前D L P投影機產品已出現0 · 8公斤的產品,但產品小变化 在市場應用需求上有其極限,再往更小型化發展的意義就| 已不太大,技術的競賽將由輕薄短小化轉向顯.影技術的改 善’例如提供高色彩飽和度、高亮度、高解析度、快速反 應速度等性能之投影機以為未來追求的主流。’ 在幾何學上,有一個形容發光或是收光的幾何極限值 稱為etendue,e tendue是一個與光束截面積以及光束發散 .A light such as a lamp or a xenon lamp emits light, collects the light to the panel to reflect or transmit the image of the panel to project the image, and then passes through the beam splitting and combining light system, and finally projects the image to the screen for display. The key technology of the DLP projector is to use a semiconductor device D0 (Digital Micromiirror Device) controlled by two-bit pulse modulation as a reflecting device and to project an image to the screen. Among them, DMD can control the digital optical switch very fast and reflectively, and it can also control the light source accurately. Each DMD wafer contains thousands of tiny square reflective lenses (micromirrors). After the light emitted by the light source (1 ight) is projected onto the surface of D0 alternately, all the micromirrors on the DMD chip are determined by the number of each color (red or green or monitor) in the corresponding graphics element. The number of times the colored light is in the on position, which determines the amount of light that is projected onto the screen through the projection lens after reflection. Since D M D has the characteristics of reflectivity and radon fill ratio, it can produce high optical efficiency ’. Therefore, DLP projectors are very suitable for applications requiring high brightness and high resolution. The better heat dissipation also allows DLp projectors to use high-wattage light sources without reducing the life of the DMD. At the same time, the all-digital design of DLP also provides a more accurate and stable reproduced image. At present, DLP projector products have appeared 0.8 kg products, but small changes in products have their limits in market application requirements, and the significance of further miniaturization | is not too great, the technology competition will shift from thinness to shortness Improvements in display technology. For example, projectors that provide high color saturation, high brightness, high resolution, and fast response speed are the mainstream pursued in the future. ’In geometry, there is a geometric limit value that describes light emission or light reception, called etendue, and e tendue is the cross-sectional area of the beam and the beam divergence.

DLP機雖為各類投影機中光能利用效率較佳的機 種彳一各廠商仍致力於提高其對於光能的使用效率,進以 確保其f商用投影機市場上能持續位於領先地位。Although DLP projectors are the ones with better efficiency of light energy utilization in various types of projectors, various manufacturers are still committed to improving their efficiency in the use of light energy to ensure that they can continue to be in the leading position in the commercial projector market.
目刖’各腐1商在光學引擎的設計中多已改採用具有雙 燈泡的新照明系統來取代傳統僅具有單一光源的照明系統 以便提局光能的利用效率。但是DLp投影機之et endue值乃 取決於所使用之DMD的規格。而雙燈泡照明系統直接合成 之光束的etendue值多較DMD所需值為大。因此若想確實提 南光能的利用效率’提供一套能適度縮小合成光束 etendue值以與DMD所需相吻合的雙光源照明系統實具有極 佳的產業價值。 職是之故,申請人鑑於習知技術之缺失,乃經悉心試 驗與研究,並一本鍥而不捨之精神,終研發出本案之「高 效率之雙燈泡照明系統」。 , 發明内容In the design of optical engines, many commercial companies have changed to adopt new lighting systems with dual light bulbs to replace traditional lighting systems with a single light source in order to improve the efficiency of light energy utilization. However, the et endue value of the DLp projector depends on the specifications of the DMD used. The etendue value of the beam directly synthesized by the dual-bulb lighting system is more than the required value of DMD. Therefore, if we want to really improve the utilization efficiency of solar energy ’, it is of great industrial value to provide a two-light source lighting system that can moderately reduce the etendue value of the synthetic beam to meet the requirements of DMD. Due to the lack of know-how, the applicant has carefully studied and researched and persevered, and finally developed the "high-efficiency dual-bulb lighting system" in this case.

Description of the invention (10) ~~ '— In addition, the size of the first plane mirror 15 and the second plane mirror 16 can be changed appropriately, and the size of the new beam can also be controlled (only after rotation The first plane mirror 15 and the second plane mirror 16 should maintain the state of the condensing lens 17 and the second condensing lens 18 to avoid unnecessary overflow of light energy. The combined light of the lens 17 and the second condenser lens 18 can control the entering light homogenization duct 19ietendue value. As mentioned above, in addition to the problem that the general spherical lens is not easy to align, the design of the present case can also achieve the purpose of reducing the volume and the size of the light spot through the design of the confocal condenser lens combination. The plane reflection i (for example, the first plane mirror 15 or the second plane mirror 16) used in this case is a movable plane mirror. Therefore, when reflecting, the plane can be adjusted as required. The angle of the mirror can be adjusted as long as it reflects. The light reflected by a parabolic mirror (such as f-parabolic mirror 13 or second parabolic mirror 14) can be received by the binocular lens combination; this can control the etendue value to meet the demand. Another advantage of this case is 1 = 2 of the mirror (the first-plane mirror 15 or the second-plane mirror 16). However, the plane mirror needs to maintain a condensing lens group that can shield the part, so as to avoid unnecessary loss of light energy), the purpose of controlling the e ten due value can be achieved by changing the size of the synthetic beam. Therefore, even if the case has been detailed from the above example ^ ancient nine warriors 4 shi r ^ m examples. The description can be taken from, Shen: People can be modified in any way, but it is not as good as the scope of the attached patent protector.
