[0003] 5见有应用于舞台灯领域的大功率 LED光源系统的原理如图 1所示, 若干辐射出 白光的 LED发光器件, 按一定规则排布成 LED阵列 (1) , 每个 LED单元与准直 透镜组一一对应设置; 多个准直透镜组构成准直透镜阵列 (2) , 用于准直 LED 阵列 (1) 发出的光线成近平行光出射; LED经准直透镜阵列 (2) 出射的光线进 入聚光镜 (3) , 聚光镜 (3) 把光线聚焦于特定的焦平面 (6) 上形成特定的照 明区域, 光源系统出射的光线夹角 (全角) 在 52°-60°之间。 而在应用端, 客户 为实现灯具颜色的多变性, 通常会在光源系统的焦平面 (6) 和聚光镜 (3) 中 间增加 CMY滤光片 (4) 来改变灯具的颜色, 以此实现灯具颜色的多样化效果。
[0004] 当在聚光镜 (3) 和焦平面 (6) 中间设置 CMY滤光片 (4) 时, 由于 CMY滤光 片 (4) 不但会透射一部分光线至焦平面 (6) , 而且也会反射一部分光线, 被 反射回来的光线至光源系统的聚光镜 (3) 上, 通过聚光镜 (3) 把反射回来的 光线给再次聚焦于安装 LED阵列 (1) 的 PCB板光轴中心区域上, 导致该区域温 度升高, 对整个光源光轴中心区域附近的光学元器件及 LED阵列 (1) 造成较严 重的损伤, 如光学元器件破裂等不良现象, 尤其是导致光轴中心区域附近的 LED 结温过高, 降低 LED寿命。
