Description

照明设备 技术领域
本发明涉及一种照明设备，特别涉及一种舞台用照明设备。
背景技术
随着近年来半导体固体光源技术的发展以及困扰全球的能源紧张、全球气候变暖等问题日益突出，半导体发光二极管 (LED) 光源以其节能、环保、光亮度及色温可控等优点，在各行各业上被广泛应用，大有取代传统光源的趋势。有理由相信，在不久的将来，随着发光二极管 (LED) 成本的降低及光效率的提高，半导体发光二极管 (LED) 光源有可能全面取代传统光源。
针对舞台灯光电脑摇头图案灯，曾提出了大功率三基色（红 (R) 、绿 (G) 和蓝 (B) ） LED 光源（如图 1 所示）。在此光源装置中，所有的合成颜色都是通过分别控制红 (R) 、绿 (G) 和蓝 (B) 三基色发光二极管 (LED) 的驱动电流来实现颜色的配比。这种方案采用三基色 LED 直接发光，因为 LED 的发光光谱为窄谱，即其光谱的宽度较小（例如绿光 LED 的发光光谱的半高全宽为 50nm 左右），所以三基色发光的单色光的颜色饱和度较高，能够满足舞台演出对颜色鲜艳度的要求。
参照图 1 ，在现有技术的照明设备中，具有分别发出红光、蓝光和绿光的发光二级管 (LED) 阵列 1 、 2 、 3 ，所述阵列包括发光二级管 6 。其所发光线经合光装置 5 、匀光装置 7 、透镜 8 等汇聚到图案片 9 上。
上述光源中三基色 LED 发出的单色光的颜色饱和度非常高，因此能够满足舞台演出对于颜色鲜艳度的要求。但采用红 (R) 、绿 (G) 和蓝 (B) 三基色 LED 光源的一个缺点是光源整体亮度输出不高，尤其是白光的亮度输出不高。
 技术问题
针对上述现有技术中的缺陷，申请人研究发现，其主要原因是目前为止，绿光芯片的发光效率远低于蓝光芯片，也低于红光芯片，同时，在合成白光时，绿光的亮度成分也不足，因而造成光源整体亮度输出不高，尤其是白光的亮度输出不高。
针对以上问题，本发明要解决的问题主要是提高光源绿光的亮度，从而提高整个光源的效率。
本发明提出了一种照明设备，包括：第一光源，用于发出红光和蓝光；第二光源，包括第一发光二极管芯片和设置在所述第一发光二极管芯片上的荧光物质，所述第一发光二极管芯片所发出的光线能够激发所述荧光物质，从而使得所述第二光源发出绿光或黄光；合光装置，其用于将来自所述第一光源的红光和蓝光以及来自所述第二光源的绿光或黄光合并在一起并输出。
在一个实施例中，还包括第二发光二极管芯片，所述第二发光二极管芯片所发出的光被引导到所述第二光源的荧光物质上并激发所述荧光物质发光。通过第二发光二级管芯片的设置，以及光学器件和光路的设置，实现了荧光物质的二次激发，大大提高了第二光源（即绿光光源）的发光效率，弥补了现有技术中的不足。

 本发明的实施方式
下面将参照附图来详细地介绍本发明。
图 2 显示了根据本发明的照明设备 50 。照明设备 50 包括第一光源 100 ，用于发出红光和蓝光。
照明设备 50 还包括第二光源 200 。图 3 详细显示了第二光源 200 的结构。参照图 3 ，第二光源 200 包括第一发光二极管芯片 12 和设置在第一发光二极管芯片上 12 的荧光物质 13 ，第一发光二极管芯片 12 所发出的光线 14 能够激发荧光物质 13 ，从而使得第二光源 200 能够发出绿光。此次激发可以称作第一次激发。第一发光二极管芯片 12 的 发光可以通过电流来驱动。
在一个实施例中，第一发光二级管芯片 12 具有相应的收光装置 30 ，用来收集第一发光二级管芯片 12 激发荧光物质 13 后所发出的光线，并将其准直成有一定发散角的光线。
再次参照图 2 ，照明设备 50 还包括合光装置 11 ，其用于将来自所述第一光源 100 的红光和蓝光以及来自所述第二光源 200 的绿光合并在一起并输出。
在一个优选的实施例中，照明设备 50 还包括第二发光二极管芯片 20 。图 3 显示了第二发光二级管芯片 20 如何与第二光源 200 相互协作。参照图 3 ，第二发光二极管芯片 20 所发出的光 15 通过光学系统（例如合光装置 11 ）被引导到第二光源 200 的荧光物质 13 上并激发荧光物质 13 。此次激发可以称作第二次激发。
优选地，在第二发光二极管芯片 20 上布置有收光装置，用于将第二发光二极管芯片 20 的光线准直到 所设定 的发散角度内。如此可以提高能量利用率，减少光的耗散。准直后的光线经过合光装置 11 的反射，再经过与第一发光二极管芯片 12 所相应的收光装置而聚焦到相应的第一发光二极管芯片 12 上的荧光物质 13 上。
图 3 中的箭头显示了光的传播路线。参照图 3 ， 第一发光二极管芯片 12 的朝向合光装置 11 的顶面上布置有荧光物质 13 ，第一发光二极管芯片 12 的远离合光装置 11 的底面能够反射光线（例如通过涂布反射膜来实现）。 由来自第二发光二极管芯片 20 的光线 15 激发荧光物质 13 （即第二次激发）所发出的光到达第一发光二级管芯片 12 的底面后被反射到合光装置 11 （图 3 中未示出）上。
由第二发光二级管芯片 20 所造成的荧光物质 13 的第 二次激发提高了荧光物质 13 的发光效率，从而提升了第二光源 200 的发光效率和绿光的强度。
为了使第二光源 200 发 出适合的绿光，在一个实施例中，第一发光二级管芯片 12 和第二发光二极管芯片 20 所发的光线为蓝光，所述第二光源 200 的荧光物质 13 为受激发产生黄光或绿光的荧光物质，例如黄色荧光粉、绿色荧光粉，而第二发光二极管芯片 20 表面没有设置荧光物质。
图 2 也示意性显示了照明装置 50 的几何构型。参照图 2 ，第一发光二极管芯片 12 封装到第二基板 22 上，第二发光二极管芯片 20 封装到第一基板上 23 ，而第一光源 100 包括封装到第三基板 24 上的红光发光二极管芯片和蓝光发光二极管芯片。
封装 LED 芯片的基板可以为陶瓷基板，或将 LED 芯片直接封装在金属基印刷电路板 (MCPCB) 上。
在一个实施例中，在第三基板 24 上，红光发光二极管芯片和蓝光发光二极管芯片的数量比处于 1/4 到 3/4 的范围内。具体数量比可根据白平衡需求来调节。第一光源 100 的红光发光二级管芯片和蓝光发光二极管芯片的排列可以为交叉排列，也可以根据具体设计需求以 所设定 的图案来排列。
在一个实施例中，第一基板 23 、第二基板 22 和第三基板 24 构成矩形的三条边，而第一基板 23 和第三基板 24 平行布置，合光装置 11 呈板状且 构成所述第二基板 22 和所述第三基板 24 的角平分线。
在合光装置 11 的第一实施例中，合光装置 11 包括滤光片，所述滤光片的朝向所述第二光源的表面上镀有透射绿光并反射红光和蓝光的滤光膜，另一面上镀有增透膜。其透光度曲线如图 4 所示，其中横轴为波长，纵轴为透光度。
在第一实施例中，来自第一光源 100 的红光和蓝光被合光装置 11 的滤光片反射朝向匀光装置 7 ，第二光源 200 中的第一发光二极管芯片 12 发出蓝光，荧光物质 13 为绿色荧光粉，则该蓝光激发绿色荧光粉发出绿光，而来自第二发光二极管芯片 20 的蓝光被合光装置 11 的滤光片反射到第二光源 200 ，并对第二光源 200 中的荧光物质 13 造成第二次激发，使得第二光源 200 整体再次发出绿光，该两次绿光透过合光装置 11 的滤光片，与来自第一光源 100 的红光和蓝光一齐投射向匀光装置 7 。该荧光物质 13 也可以是黄色荧光粉，从而受激发产生黄光。黄光达到合光装置 11 的滤光片，分出的绿光透射，而分出的红光被反射。
图 5 显示了第二实施例中的根据本发明的照明设备 50 的合光装置 11 的结构示意图。在第二实施例中，合光装置 11 包括滤光片，所述滤光片在第一表面上镀有反射蓝光并透射红光和绿光的第一滤光膜 25 ，所述滤光片在第二表面上镀有反射红光并透射蓝光和绿光的第二滤光膜 26 。如图所示，第一表面可以为朝向第二光源 200 的表面，而第二表面可以为朝向第一光源 100 的表面。
图 6 显示了第二实施例中的根据本发明的照明设备 50 的合光装置 11 的第一滤光膜 25 的透光度曲线 16 。其中横轴为波长，纵轴为透光度。优选地，第一滤光膜 25 的截止波长处于 470nm-510nm 的范围内；图 7 显示了第二实施例中的根据本发明的照明设备 50 的合光装置 11 的第二滤光膜 26 的透光度曲线 17 。其中横轴为波长，纵轴为透光度。优选地，第二滤光膜的截止波长处于 550nm-620nm 的范围内。
在第二实施例中，来自第一光源 100 的蓝光被合光装置 11 的滤光片的第一滤光膜 25 反射朝向匀光装置 7 ，来自第一光源 100 的红光被合光装置 11 的滤光片的第二滤光膜 26 反射朝向匀光装置 7 ，荧光物质 13 为绿色荧光粉，第二光源 200 中的第一发光二极管芯片 12 发出的蓝光激发荧光物质 13 以发出绿色的光线，而来自第二发光二极管芯片 20 的蓝光被合光装置 11 的滤光片的第一滤光膜 25 反射到第二光源 200 ，并对第二光源 200 中的荧光物质 13 造成第二次激发，使得第二光源 200 整体发出两次绿光，该两次绿光透过合光装置 11 的滤光片的第一滤光膜 25 和第二滤光膜 26 ，与来自第一光源 100 的红光和蓝光一齐投射向匀光装置 7 。同样，荧光物质 13 也可为黄色荧光粉，受蓝光激发产生黄光，其穿过第一滤光膜 25 ，并在第二滤光膜 26 上分出绿光透过第二滤光膜 26 ，而分出的红光被反射并透过第一滤光膜 25 出射。
图 8 显示了第三实施例中的根据本发明的照明设备 50 的合光装置 11 的结构示意图。参照图 8 ，在第三实施例中，合光装置 11 包括两个滤光片 111 、 112 ， 最靠近第二光源 200 的滤光片 111 的朝向第二光源 200 的表面上镀有反射蓝光并透射红光和绿光的第三滤光膜 27 ，最远离第二光源 200 的滤光片 112 的背向第二光源 200 的表面上镀有反射红光并透射蓝光和绿光的第四滤光膜 28 。优选地，可以在其余的滤光片表面上镀增透膜 29 ，以增大透光度。
在第三实施例中，来自第一光源 100 的蓝光被合光装置 11 的滤光片 111 的第三滤光膜 27 反射朝向匀光装置 7 ，来自第一光源 100 的红光被合光装置 11 的滤光片 112 的第四滤光膜 28 反射朝向匀光装置 7 ，第二光源 200 中的第一发光二极管芯片 12 发出的蓝光激发荧光物质 13 以发出黄色或绿色的光线，而来自第二发光二极管芯片 20 的蓝光被合光装置 11 的滤光片 111 的第三滤光膜 27 反射到第二光源 200 ，并对第二光源 200 中的荧光物质 13 造成第二次激发，使得第二光源 200 整体发出绿色光，该绿色光透过合光装置 11 的滤光片 111 和滤光片 112 ，与来自第一光源 100 的红光和蓝光一齐投射向匀光装置 7 。
在上述实施例中，两个滤光片之间具有宽度位于 0.1mm-5mm 的范围之内的气隙。当然，这两个滤光片也可以通过光学胶粘贴到一起而不具有气隙，其胶合面不镀膜。
在另一个附图未示出的实施例中，照明设备 50 也可以具有不同的光学几何构造。其中，上述第一基板、第二基板和第三基板构成矩形的三条边，而第一基板和所述第二基板平行，同时合光装置 11 呈板状且 构成第二基板和第三基板的角平分线，同时合光装置 11 能够反射绿光并透射红光和蓝光。即将图 2 中的第一光源 100 和第二光源 200 交换位置，同时相应改变合光装置 11 的光学性质。如此布置，照明设备 50 的光学效果不变，同样可以提升第二光源的发光效率和绿光的饱和度。
再次参照图 2 ，根据本发明的照明设备 50 还包括用于将来自合光装置 11 的光线均匀化的匀光装置 7 、将均匀化后的光线聚焦的透镜 8 以及图案片 9 ，透镜 8 将光线聚焦到图案片 9 上。
参照图 9 ，当合光装置 11 的带宽比较宽时，绿光的颜色饱和度不高，颜色不鲜艳，另外，其色域也比较小，特别是蓝绿光的表现。因此，在一个优选的实施例中，当要表现饱和的绿光或蓝绿光时，照明设备 50 还包括按照光路方向设置在图案片 9 下游的透射绿光并反射红光和蓝光的下游滤光片 10 ，用于保证绿光的饱和度。优选地，下游滤光片 10 的短波段截止波长可以为 500nm 附近 ，长波段截止波长可以为 550nm 附近 。
下游滤光片 10 的光谱透过率也可如图 4 所示。参照图 4 ，其带宽较窄 ， 以保证透过绿光的饱和度，其短波段部分截止波长位于 500nm 左右，长光波段的截止波长位于 550nm 左右。当需要高亮度的白光时，可以将下游滤光片 10 旋转到光路外，这样可以获得高亮度的白光。
根据本发明的照明设备 50 具有如下优势：第一，由于绿光亮度的提高，可以显著提高系统的整体亮度；第二，由于绿光为宽光谱，在由三基色合成白光时，可以提高光谱的连输性，提高光源的显色性；第三，虽然光源的显色性提高，仍然可以通过滤光片来获得高饱和度的绿光，而且不会影响 RGB 系统的混色；第四，根据实际需要，可以获得宽色域高饱和的绿光和高亮度白光的高显指色域系统。
图 10 显示了根据本发明的照明设备 50 的光谱对比图。其中横轴为波长，纵轴为功率。可以从中看出本发明的增设下游滤光片 10 的优选实施方案所带来的有益效果。
图 11 显示了根据本发明的照明设备 50 的白光光谱对比图。其中横轴为波长，纵轴为功率。可以看到根据本发明的增设第二发光二极管芯片和进行荧光物质的二次激发的优选实施方案所带来的有益效果。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
