光源系统 The light source system

技术领域 FIELD

[0001] 本发明涉及一种光源系统,特别涉及一种用于投影装置的光源系统。 [0001] The present invention relates to a light source system, and particularly relates to a light source system for a projection apparatus.

背景技术 Background technique

[0002] 发光二极管(LED)具有启动时间短及使用寿命长的优点,已广泛取代传统高压汞灯作为一般投影装置的光源。 [0002] The light emitting diode (LED) having a short start-up time and the advantage of long life, has been widely replace conventional high pressure mercury lamp as a light source of a general projector apparatus.

[0003] 一般而言,投影系统通过发光二极管提供不同方向投射的三原色光束(红、绿、蓝),经过合光元件合成一道全色光(白光)后,射出至投影装置的光阀(例如DMD、IXD或LCoS)。 [0003] In general, the projection system to provide different directions projected light beam by the light emitting diodes of three primary colors (red, green, blue), the light combination element synthesizing a full-color light (white light) passes to the emitted light valve projection device (DMD e.g. , IXD or LCoS). 但由于绿色发光二极管提供的绿色光束的强度与红色或蓝色发光二极管的红色或蓝色光束的强度相比,较为弱,会导致投影装置投射出的影像的绿色亮度偏低,造成该影像看起来不自然。 However, the strength or intensity of the blue green light red green LED to provide a light emitting diode or a blue light beam as compared to red, it is weak, green luminance projection device will cause the projected image is low, causing the image to see it is not natural.

[0004] 因此,业界发展出一种可增加绿光强度的光源系统。 [0004] Accordingly, the industry developed a green light intensity of the light source system may be increased. 请参阅图1,光源系统I包括一红色发光二极管11、二蓝色发光二极管13、15以及一紫外光发光二极管17。 Please refer to FIG. 1, a light source system I comprises a red light emitting diode 11, and two blue light emitting diode 13, 15 an ultraviolet light emitting diode 17. 红色发光二极管11与蓝色发光二极管13是分别用以提供光源系统I的红色光束及蓝色光束。 A red LED 11 and the blue light emitting diode 13 are used to provide a red light beam and the blue beam light source system I. 蓝色发光二极管15及紫外光发光二极管17分别通过二分光镜19a、19b,激发一绿色焚光粉12,以提供光源系统I亮度足够的绿色光束。 Blue light emitting diodes and ultraviolet light emitting diodes 15 through 17 are two beam splitter 19a, 19b, a green excitation light burning powder 12 to provide a light source system I sufficient brightness green beam.

[0005] 由于上述的光源系统I需要有多个分光镜,且每个发光二极管皆需配置一透镜,使得投影装置的尺寸增加。 [0005] Since the above light source system needs to have a plurality of I beam splitter, and each light emitting diode units are required to configure a lens, so that the size of the projection apparatus is increased. 若减小投影装置的体积,则需将光源系统的光源架构缩小,其亮度亦会相对降低。 When the volume is reduced projection apparatus, light is required to source system architecture is reduced, the brightness will be relatively reduced. 且光源系统I所提供绿色光束仍不具有足够的强度能与红色或蓝色光束的强度匹配。 The light source and the green light beam provided by the system I still have sufficient strength to match the intensity of the red or blue light beam.

[0006] 有鉴于此,提供一种可增加特定颜色的光线(例如绿光)的强度及缩减体积的光源系统,乃为此一业界亟欲达成的目标。 [0006] In view of this, there is provided capable of increasing the target light of a specific color (e.g., green) strength and reduce the volume of the light source system, is anxious to reach the industry for this purpose a.
