Description

高效合光的舞台灯光照明装置
技术领域 本发明涉及照明装置或其***的功能特征或零部件， 具体来说， 尤其涉及主 要用于舞台灯光照明的照明***及其合光装置。
背景技术 LED (发光二极管）光源为绿色无污染的干净节能光源， 其可达到的光通量设 计指标在逐年提升。 目前 LED光源主要应用于一些小功率、 低端的换色灯产品上。 大功率舞台灯光光源主要采用金卤放电泡。 金卤放电泡为白色光源， 使用寿命较低， 一般为几百小时到数千小时不等。 因金卤放电泡的发光谱为白色连续光谱， 舞台灯光所需 的不同色彩只能靠彩色滤光片来滤光实现， 使得灯光投射出的图案具有较低的色彩饱和度， 色彩既不鲜艳， 也不丰富。 若舞台灯光采用 LED光源， 则可以省掉所述彩色滤光片， 并通过调节不同基色 LED的 电流来改变光源的颜色， 从而利用单色 LED 较高的色彩饱和度， 可使舞台灯光色彩的表现 自由度大为提高。 但目前 LED发热量大， 发光效率还不够高， 且单个 LED芯片不能承受高 功率， 因此大功率舞台灯光的高光通量往往要靠 LED阵列来实现。 申请号为 200720061982. 0的中国专利公开了一种舞台灯的光源组件， 釆用一个 LED阵 列和大型散热装置， 可以提供一百瓦的发光功率， 并可通过控制点亮该 LED 阵列中交错排 列的不同色的 LED来实现色彩调整。 上述现有技术的不足之处在于： 当控制 LED阵列中交错排列的 R、 G、 B不同色 LED来 产生白光时， 灯光装置输出光斑的亮度及颜色均匀性较差， 因此该类灯通常适用于对光均 匀度要求比较低的帕灯、 洗墙灯或泛光灯上； 且当对灯光装置输出功率要求较大时， 随着 LED阵列规模的扩大， 灯光装置的体积、 光学扩展量变大， 极可能造成对 LED光线的收集 效率下降。 因此， 现有技术难以满足大功率摇头图案灯对性能的高要求。 发明内容 本发明要解决的技术问题是针对上述现有技术的不足之处， 而提出一种舞台 灯光照明装置， 以高效的合光效率来提供光输出亮度及颜色的良好均匀性。 作为解决本发明技术问题而提出来的技术方案是， 提供一种高效合光的舞台灯光照明 装置， 包括至少两个封装在散热基板上的 LED阵列， 尤其是， 同一所述 LED阵列上的各 LED 芯片均为一同色 LED芯片； 还包括与各所述 LED阵列相对应的包括复数个透镜的透镜阵列， 每一所述透镜对准一 LED芯片以将该 LED芯片的输出光准直成***行光; 还包括一个分光 合色装置， 将源自各 LED 芯片的所述***行光汇聚成一束， 投射往一聚焦透镜, 通过该聚 焦透镜聚焦到该舞台灯光照明装置的光出口。 上述方案中， 该舞台灯光照明装置或者包括两个所述 LED 阵列， 所述分光合色装置为 一合色滤光片， 分别通过透射和反射的方式将源自该两个 LED阵列的***行光汇聚成一束; 或者包括三个所述 LED阵列， 所述分光合色装置为一个 X型合色滤光装置， 该 X型合色滤 光装置的三个光入口端分别对准一个 LED阵列及该 LED阵列所对应的透镜阵列。 上述方案中， 所述 X 型合色滤光装置或者是由三片合色滤光片垂直交又构成的分光合 色片组， 其中两片具有相同的光学特性， 分别紧贴另一片的两面； 或者是由四块分光合色 直角棱镜顶角相对粘合而成的分光合色棱镜组。 所述合色滤光片或者为二向色片， 或者为 镀有分光滤光膜的玻璃片。 上述方案中， 舞台灯光照明装置还包括固定各所述散热基板的定位装置， 在该定位装 置上包括对所述散热基板位置进行平移微调的至少一个调节装置。 上述方案中， 在所述定位装置上还包括对所述散热基板位置进行转动微调的至少一个 角度调节装置。 上述方案中， 舞台灯光照明装置还包括固定所述分光合色装置的定位装置, 在该定位 装置上包括对所述分光合色装置方位进行微调的调节装置。 上述方案中， 所述调节装置包括滑动槽、 齿轮、 调整螺钉、 紧定螺钉或弹簧。 上述方案中， 各所述 LED阵列紧贴所述透镜阵列， 使得各 LED与对应的透镜之间仅留 有厚度小于 1. 5亳米的空气隙。 上述方案中， 舞台灯光照明装置还包括图案盘， 该图案盘所携带的图案片之一正对所 述光出口。 采用上述各技术方案， 不仅使灯光装置具有良好的亮度及颜色合光效果， 还使灯光装 置提高输出功率的同时体积更为紧凑， 光学扩展量更小。 附图说明 图 1示意了本发明舞台灯光照明装置的结构之一；

具体实施方式 下面， 结合附图所示之最佳实施例进一步阐述本发明。 如图 1所示， 本发明舞台灯光照明装置包括至少两个封装在散热基板上的 LED阵列 1， 同一所述 LED阵列 1上的各 LED芯片均为一同色 LED芯片； 还包括与各所述 LED阵列相对 应的包括复数个透镜的透镜阵列 2， 每一所述透镜对准一 LED 芯片以最大限度地收集从该 LED芯片发出的大角度光， 并将该 LED芯片的输出光转为具有一定发散角的***行光， 此 ***行光角度越小越好； 还包括一个分光合色装置 3, 将源自各 LED的所述***行光汇聚成 一束， 投射往一聚焦透镜 4 , 通过该聚焦透镜 4聚焦到该舞台灯光照明装置的光出口 5。
该图中以包括三个 LED阵列为例， 主要便于利用 R (红）、 G (绿）、 B (蓝） 三基色的 LED来合成各种颜色的输出光。 所述分光合色装置 3为一个 X型合色滤光装置, 该 X型合 色滤光装置的三个光入口端分别对准一个 LED阵列及该 LED阵列所对应的透镜阵列。如图 2 所示， 所述 X型合色滤光装置可以是由三片合色滤光片 30 - 32垂直交叉构成的分光合色片 组， 其中两片 31、 32具有相同的光学特性， 分别紧贴另一片 30的两面。 所述合色滤光片 30 - 32 可以是二向色片， 也可以是镀有分光滤光膜的玻璃片。 通常根据其使用面积大小， 所述合色滤光片的厚度选择为 0.5毫米， 0.7亳米或是 1.1毫米。 如该图所示， 以镀有分光 滤光膜的玻璃片为例， 所述合色滤光片 30可以在 S1面上镀反蓝光透红、 绿光的滤光膜， 在 S2面上鍍增透膜来增加光线的透过率。 所述合色滤光片 31、 32可以在 S4面上镀反红光 透蓝、 绿光的滤光膜， 在 S3面上镀增透膜来增加光线的透过率。 则当所述 R、 G、 B LED 芯片均被点亮时， 该 X型合色滤光装置将输出均匀混合的白光； 相对于传统光合成方式， 该 X型合色滤光装置具有光学透过率高， 体积紧凑， 易于实现大功率光合成的优点， 尤其 可以使合成光的光学扩展量保持不变。
如图 3所示意， 所述 X型合色滤光装置 3可以采用由四块分光合色直角棱镜顶角相对 粘合而成的分光合色棱镜组 6 来替换。 其不足之处在于分光合色直角棱镜的制作工艺相对 较为复杂， 成本偏贵， 且对入射光的角度比较敏感， 对镀膜的要求会较高。 如图 5 所示， 本发明舞台灯光照明装置还包括固定各所述散热基板的定位装置， 在该 定位装置上包括对所述散热基板位置进行平移微调的至少一个调节装置，可以是滑动槽（如 图 5b )或齿轮， 用来修正由 R、 G、 B三色 LED芯片位置偏离所带来的合光偏色。 在所述定 位装置上还可以包括对所述散热基板位置进行转动微调的至少一个角度调节装置， 例如但 不限于（如图 5a所示的）调整螺钉或紧定螺钉、 弹簧， 用来修正 LED阵列角度倾斜所带来 的合光色彩不匀。
本发明舞台灯光照明装置还包括固定所述分光合色装置的定位装置。 可以用设置在该 定位装置上的对所述分光合色装置方位进行微调的调节装置来替代上述基于散热基板的调 节装置， 或作为该基于散热基板的调节装置的补充。 如图 4所示， 若在所述透镜阵列 2与芯片之间填充硅胶， 虽可增加光源的光通量（增 加的倍数小于 n2， 其中 n为透镜的折射率）， 但光学扩展量也将增加 n 2倍， 从而对投影 FN0 ( FN0 =焦距 /入射孔径或有效口径） 受限的***来说， 光会有很大的损失。 为此， 本发明 舞台灯光照明装置令各所述 LED阵列 1紧贴所述透镜阵列 2，中间例如但不限于用网状支架 11来支承和隔离， 使得各 LED芯片与对应的透镜之间仅留有厚度小于 1. 5亳米的空气隙， 将使光源保持最小的光学扩展量， 从而大大提高对 LED 芯片发光的利用率。 试验验证， 空 气隙越小， 越有利于光学收集。 本发明舞台灯光照明装置还可以包括图案盘， 携带有一张或一张以上的图案片。 被选 中的所述图案片可以正对所述光出口 5。 在***对颜色种类要求不高的场合， 本发明舞台灯光照明装置或许可以如图 6 所示， 仅包括两个所述 LED阵列 1 ; 所述分光合色装置 3为一合色滤光片， 分别通过透射和反射的 方式将源自该两个 LED阵列的***行光汇聚成一束。
