Description

一种新型激光与LED混色光源系统 技术领域
本发明涉及舞台灯光灯具技术领域，尤其涉及半导体光源和LED光源光学整形装置。
背景技术
很长一段时间以来，舞台灯光灯具都是采用高强度气体放电泡作为光源，它有着明显的缺陷，近年来，随着光源技术的发展，因为LED有着更高的使用寿命，更有利的环保性和更好的节能效果，所以世人都寄望用LED来取代高强度气体放电泡。但LED光源，由于其发光面积大、单位面积的光功率低，所以其实际使用的光效较低，为了提高其光源利用率，只能减小后续光学成像系统的F数，但由此又增加了后续光学成像系统的设计难度和复杂性，使成本也大幅上升，使得LED无法真正取代高强度气体放电泡在舞台灯光灯具中的应用。
目前舞台灯光的灯具的光源系统，是采用灯泡(高强度气体放电泡)或LED作为光源。其高强度气体放电泡的缺陷为：
1、高强度气体放电泡的极距较长(6毫米左右)，导致光源体积大，整体笨重。
2、近年来高强度气体放电泡的极距较短(1-2毫米)，导致光源与光学成像系统的匹配性差，影响灯具的整体成像质量和灯具出射光通量的分布(即均匀性)；且极距较短的气体放电泡还导致散热系统难以设计，其散热系统难以设计，则会导致光通量的提高很困难以及导致光衰迅速，使用寿命过短，大大提高使用成本。
3、显示色彩不丰富，色域窄，颜色呆板。
4、色温不可调节，通用性差。
5、含有汞等有害物质，频繁更换导致破坏环境。
LED的缺陷：
1、显示色彩不丰富，色域窄，颜色呆板。
2、发光面积大、单位面积的光功率低，所以其实际使用的光效较低。
3、如果提高其光源利用率，只能减小后续光学成像系统的F数，但由此又增加了后续光学成像系统的设计难度和复杂性，使成本也大幅上升。
4、色温不可调节，通用性差。
发明内容
为解决上述技术问题，本发明的目的是提供一种新型激光与LED混色光源系统，该系统光效高、色域广、使用寿命长、可调节色温、环保、与光学成像系统匹配性好的光源系统。
本发明的目的通过以下的技术方案来实现：
一种新型激光与LED混色光源系统，包括：
第一光源、第一透射系统、分光系统、第二透射系统、荧光色轮、第二光源、第三透射系统和第四透射系统；所述
第一光源，发出入射蓝色激光，蓝色激光经第一透射系统会聚到分光系统上；
第一透射系统，用于将第一光源发出的大口径蓝色激光光束整形压缩为小口径激光光束，并保持大口径激光光束平行性；
分光系统，将小口径平行激光光束反射得到反射激光光束，并保持光束口径及平行性；
第二透射系统，用于将反射激光光束整形压缩为更小口径的激光光束，且改变反射激光光束平行性，会聚到所述荧光色轮上；
荧光色轮，通过接收到的激光光束激发自身的荧光粉，使荧光粉发出红色可见光和绿色可见光的双色光组合，或单独黄色可见光；
红色可见光和绿色可见光的双色光组合，或单独黄色可见光通过所述第 二透射系统进行整形压缩，形成准直光束，并到达分光系统，通过分光系统出射得到准直的第一光束；
第二光源，发出入射蓝色可见光，蓝色可见光经第三透射系统会聚到分光系统上；
第三透射系统，用于将第二光源发出的可见光光束整形压缩为准直光束，并会聚到达分光系统；
分光系统反射会聚后的准直光束，出射得到准直的第二光束；
将准直的第一光束和准直的第二光束合成为准直的第三光束；
第四透射系统，将准直的第三光束整形压缩，会聚到舞台灯具上的光阀上。
与现有技术相比，本发明的一个或多个实施例可以具有如下优点：
1、本发明因同时采用激光和LED光源，且激光光源采用多组激光器，每组激光器电功率至少100瓦，从而能显著提升光效和亮度，克服了LED在舞台灯光灯具中有效利用的光效率低、亮度难以提高的缺陷。
2、设计精巧、结构简洁、各系统之间衔接合理，从而有效地提高了光能利用率。
3、不同于传统高强度气体放电泡难以设计散热系统从而令其光衰很快和频繁更换，激光光源的散热系统设计简易、加工成熟，从而令激光光源光衰缓慢，输出稳定。
4、采用激光光源，其中一个优势在于光衰缓慢和输出稳定，这就决定了激光光源具有比传统高强度气体放电泡更长的使用周期和更低廉的使用成本。
5、采用激光作为光源，其显示的颜色包含人眼能分辨颜色的百分之九十，因此能显示出更丰富的颜色，带来更宽的色域。
6、通过调节荧光色轮上荧光粉的比例和空间排列，能自如地调节灯具的色温，使灯具能在不同领域使用，增加其通用性。
7、不同于传统高强度气体放电泡含有汞等有害物质，完全无有害物质排放，符合国际环保意识和要求。
8、设计巧妙，各系统独立性高，因此只需更换某部分系统，便能适用于后续多种光学成像系统的设计，具有良好的成像系统匹配性。

以下为上述技术特征的详细描述：
上述第一光源1是由一个或若干个相同的激光器，按发光面积最小化的方式排列而成的激光器阵列(如图2所示)。激光器发出的蓝色激光，其波长介于445纳米至460纳米。由于激光具有很好的方向性，激光器发出的蓝色激光可视为平行光2。
上述第一透射系统3由一个或若干个光学玻璃或塑料材料组成的光学系统。第一透射系统内的镜片，可不含非球面镜片，也可含一个或若干个非球面镜片。分光系统5是一个或若干个光学玻璃或平板玻璃组成，其单面或双面镀膜，镀膜后使得可见光某波长带宽高度截止，可见光某波长带宽高度透过。分光系统5放置的角度，与第一透射系统3的光轴成45°。第一透射系统3把第一光源1发出的大口径激光光束2，整形压缩成小口径激光光束4，且小口径激光光束4依然保持大口径激光光束2的平行性，最终小口径平行激光光束到达在分光系统5上。
小口径平行激光光束，到达分光系统5后，由分光系统5反射得到反射激光光束6，保持其口径和平行性。
第二透射系统7是由一个或若干个光学玻璃或塑料材料组成的光学系统。第二透射系统7内的镜片，可不含非球面镜片，也可含一个或若干个非球面镜片。荧光色轮8是由不同颜色的荧光粉、按一种或若干种空间排列而成的装置。第二透射系统7把反射激光光束6，再整形压缩成更小口径的激光光束9，且改变反射激光光束6的平行性，以会聚的形式到达荧光色轮8上。
到达荧光色轮8的会聚激光光束9，激发荧光色轮上的荧光粉，从而使荧光色轮发射出红色可见光和绿色可见光的双色光组合，或单独黄色可见光10。红色可见光的波长介乎于600纳米至650纳米，绿色可见光的波长介乎于500纳米至550纳米，黄色可见光的波长介于520纳米-560纳米；此时的 红色可见光和绿色可见光的双色光组合，或单独黄色可见光呈发散状态。
第二透射系统7把红色可见光和绿色可见光的双色光组合，或单独黄色可见光，整形压缩成准直的红色可见光和绿色可见光的双色光组合，或单独黄色可见光11，准直红色可见光和绿色可见光的双色光组合，或单独黄色可见光11再到达分光系统5上。准直红色可见光和绿色可见光的双色光组合，或单独黄色可见光光束的口径介乎于φ25至φ35。
红色可见光和绿色可见光的双色光组合，或单独黄色可见光光束11到达分光系统5后，再从其出射，保持其准直性。此时从分光系统出射的准直光束为第一光束12。
第二光源13由一个或若干个相同的LED，按发光面积最小化的方式排列而成的LED阵列。LED发出的蓝色可见光14，其波长介乎于450纳米至470纳米，与第一光源1发射的激光波长不同。LED发出的蓝色可见光14呈发散状态。
第三透射系统15是由一个或若干个光学玻璃或塑料材料组成的光学系统。第三透射系统15内的镜片，可不含非球面镜片，也可含一个或若干个非球面镜片。第三透射系统15把第二光源13发出的蓝色可见光光束14，整形压缩成准直的蓝光光束16，准直光束再到达分光系统5上。准直蓝光光束16的口径介乎于φ25至φ35。
准直蓝光光束16，到达分光系统5后，由分光系统5反射使其出射，保持其准直性。此时从分光系统出射的准直光束为第二光束17。
第一光束12和第二光束17，因两者传播方向一致，两者都是准直光束，且两者光束口径相同，因此两者合成可得可见光全波段高度透过的白色可见光，且保持第一光束和第二光束的准直性。此时的准直白色可见光光束为第三光束19。
第四透射系统18是由一个或若干个光学玻璃或塑料材料组成的光学系统。第四透射系统18内的镜片，可不含非球面镜片，也可含一个或若干个非球面镜片。第四透射系统18把准直的第三光束19整形压缩，最后以会聚的形式到达舞台灯光灯具上的光阀20上。再者，只需更换第四透射系统18，前述所有系统不需改变，便可适应不同尺寸的光阀20。
舞台灯光灯具上的光阀20被照亮，为后续光学成像系统提供物。
上述实施例提供的光源，重点在于：
采用半导体蓝色激光和LED光源，且激光光源采用多组激光器，能显著提升光效和亮度，克服了高强度气体放电泡和LED光效低、亮度难以提高的缺陷。
设计精巧，结构简洁，各系统之间衔接合理，从而有效地提高光能利用率。
不同于传统高强度气体放电泡难以设计散热系统从而令其光衰很快和频繁更换，激光光源的散热系统设计简易、加工成熟，从而令激光光源光衰缓慢，输出稳定。
采用的激光光源，其中一个优势在于光衰缓慢和输出稳定，这就决定了激光光源具有比传统高强度气体放电泡更长的使用周期和更低廉的使用成本。
采用激光作为光源，其显示的颜色包含人眼能分辨颜色的百分之九十，因此能显示出更丰富的颜色，带来更宽的色域。
通过调节荧光色轮上荧光粉的比例和空间排列，能自如地调节灯具的色温，使灯具能在不同领域使用，增加其通用性。
不同于传统高强度气体放电泡含有汞等有害物质，完全无有害物质排放，符合国际环保意识和要求。
设计巧妙，各系统独立性高，因此只需更换某部分系统，便能适用于后续多种光学成像系统的设计，具有良好的成像系统匹配性。
虽然本发明所揭露的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所揭露的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
