Description

一种利用混合光源的投光装置和投光方法 技术领域
本发明主要涉及投影灯领域，更具体地，涉及一种利用混合光源的投光装置和投光方法。
背景技术
随着科技的高速发展，现在人们对舞台灯具的美术造型的要求越来越高，功能要求也越来越多，该行业竞争越来越来激烈。高性价比、小型化是舞台灯市场的发展所趋。
现有技术中，舞台照明灯具的美术造型和灯光效果主要依靠图案盘的花样和数量表达。现有的图案片上一般只有一种形状，且图案形状比较单调，图案片安装在盘体上的结构比较复杂，图案片与图案片之间主要通过设置齿轮结构来转动和设置切换结构来切换形状。齿轮之间很容易出现卡死或转换不协调的情况，影响舞台效果。
为了满足不同光源照明的要求，人们对图案盘的设计要求越来越高。但目前使用的图案盘要么只是满足单一光源的使用；要么需要结合多种图案盘结构及其特定的驱动方式，才能实现在同一台舞台灯上同时满足不同光源使用的要求；且目前市场上的图案盘结构复杂、图案片图案单一、图案数量不够多，远远满足不了人们对舞台灯具美术造型的需求。
发明内容
为克服现有的技术缺陷，本发明提供了一种利用混合光源的投光装置和投光方法，本发明与现有技术相比，具有图案形状多，且结构相对简单，还可满足不同光源的使用要求，性价比更高的有益效果。

一种利用混合光源的投光装置，包括遮光板和至少两种光源，所述遮光板上至少设有两种图案，所述光源与所述图案一一对应，所述光源所发出的光束投射在所述遮光板上，呈现出与之对应的图案。
现有的舞台投影灯虽然能投影出各种色彩和形状的图案，但若要实现遮光板的形状转换则比较繁琐，技术也比较复杂，且投影出的图案效果比较单一。本发明设有至少两种光源，既可以满足不同投影灯对不同光源的需要，又可以通过点亮不同的光源来实现投影图案的多种多样，应用性更广。本发明的遮光板与现有 技术的遮光板也有很大的不同。虽然现有技术中的遮光板也设有各种图案，但其图案要么只能全部呈现，要么只能单个呈现，呈现的图案和方式还是比较单一。本发明的遮光板上至少设有两种图案，且光源与图案一一对应，点亮不同的光源能照亮不同的图案，即投影出的图案形状不仅由图案本身决定，还可以受光源的控制，实用性更强。
作为优选，所述遮光板上设有驱动遮光板盘体转动，使遮光板选择性地处于有效遮挡光束位置和不遮挡光束位置的驱动装置。
作为优选，所述至少两种光源包括呈分离或嵌套分布的第一光源和第二光源，所述至少两种图案包括呈分离或嵌套分布的图案A和图案B，所述第一光源/第二光源/第一光源和第二光源所发出的光束投射在所述遮光板上，至少投射出图案A的形状/图案B的形状/图案A和图案B共同组成的形状。
以所述的投光装置包括两种光源举例，两种光源的主要分布状态为分离和嵌套，其对应图案设置形式为分离或嵌套，分离状态的光源对应分离形式的图案，点亮不同光源，能呈现出光源所对应的图案。
作为优选，所述第一光源和所述第二光源呈左右/上下分布，所述图案A和所述图案B在所述遮光板上呈左右/上下分布，所述第一光源/第二光源/第一光源和第二光源所发出的光束投射在所述遮光板上，至少投射出图案A的形状/图案B的形状/图案A和图案B共同组成的形状。

对应光源与对应图案的尺寸相匹配是指小光源所发出光束的尺寸只能投射出小光源对应的小图案，但大光源所发出光束的尺寸因为覆盖了小光源的尺寸，所以能投射出大图案和小图案。例如当小光源为第一光源，小图案为图案A时，只有第一光源亮时，只能呈现出图案A的形状，只要有第二光源亮时，则能呈现出图案A和图案B的形状。
作为优选，所述第一光源和所述第二光源呈嵌套分布结构，所述图案A和所述图案B也呈嵌套分布结构，第一光源/第二光源所发出光束的形状与对应的图案A/图案B的形状相匹配，所述第一光源/第二光源/第一光源和第二光源所发出的光束投射在所述遮光板上，至少投射出图案A的形状/图案B的形状/图案A和图案B共同组成的形状。
对应光源与对应图案的形状相匹配是指对应光源所发出的光束的形状与对应图案的形状一样。例如第一光源所发出光束的形状为长方形，图案A的形状也是长方形；则光源所发出的光束投射在图案A上呈现出来的图案也是长方形；第二光源所发出光束的形状为圆形，图案B的形状也是圆形；因为图案A嵌套在图案B内，则光源所发出的光束投射在图案B上呈现出来的图案是内环为长方形，外环为圆形的环形图案；当两种光源同时亮时，则图案A和图案B的形状均能呈现。
一种利用混合光源的投光装置，包括遮光板和混合光源，其特征在于，所述遮光板上设有若干个图案区域，每个图案区域对应一种混合光源，所述每个图案区域中至少包括两个图案，所述混合光源中每个光源所发出的光束投射到与之对应的图案上，所述每个图案的尺寸与对应光源所发出光束的尺寸相匹配。
光源所发出的光束投射在其对应图案上的光斑大小与其对应的图案的尺寸相匹配，使得光源照射该图案区域时，投影出该图案的完整光斑。光源可以根据需要发射光束，投射出其对应图案上的图案形状，达到舞台灯光投射出特定图案形状的效果。
作为优选，所述遮光板上设有驱动遮光板盘体转动，使遮光板选择性地处于有效遮挡光束位置和不遮挡光束位置的驱动装置。
作为优选，所述若干个图案区域间隔设置并环绕在所述遮光板中心的周围。

上述方案中，通过在LED光源及第二导光组件正对第一导光组件的位置上设有开口，使得激光光源发射的光从第一导光组件穿射出后依次经过多个光学镜头组件后即可形成光束出光模式，LED光源发射的光从第二导光组件穿射出后依次经过多个光学镜头组件后即可形成图案出光模式，通过切换激光光源和LED光源的工作，即可切换光束效果和图案效果，该舞台灯光学系统，结构简单，降低了制造成本，而且在切换光束效果和图案效果时操作也比较方便，另外，由于使用激光光源形成光束出光模式，使得该舞台灯光学系统的光束效果更好。
作为优选，从第一导光组件穿射出的光与从第二导光组件穿射出的光具有相同的焦点。所述照明系统的第一光源和第二光源具有相同的焦点距离B1。
这样设置使得激光光源发射的光从第一导光组件穿射出后能与从第二导光组件穿射出的LED光汇聚到同一个焦平面上，以保证从多个光学镜头组件出来的光束效果和图案效果达到最佳。
作为优选，所述激光光源的光束中心与LED光源的环状光源中心均位于主光轴上。

实施例1
如图1所示，一种利用混合光源的投光装置，包括遮光板2遮光板2上设有若干个图案区域1，每个图案区域1上至少设有两种图案，所述两种图案分别为呈嵌套分布的图案A和图案B。
如图2第一种情况所示，一种利用混合光源的投光装置，还包括至少两种光源，所述至少两种光源包括呈嵌套分布的第一光源301和第二光源401，所述光源与所述图案一一对应。所述光源所发出的光束投射在所述遮光板2上，呈现出与之对应图案的形状。
如图3所示，图3为某一图案区域1的放大示意图。本实施例的图案区域1上的图案A为正方形图案，图案B为十字架图案。图案A和图案B分别设有一个外切圆，图案A嵌套在图案B内，图案A与图案B的中心点一致。
如图4所示，所述每个光源的轴心在同一轴线上，且所述每个光源的轴心与所对应图案的中心在同一轴上。所述至少两个光源中每个光源所发出的光束投射到与之对应的图案上，所述每个图案的尺寸与对应光源所发出光束的尺寸相匹配。这样设置能使光源所发出的光发射在嵌套型图案中时，光分布得更均匀，进而使图案表达得更完整、清晰和均匀。
本实施例中，所述第一光源301射出的光束的尺寸与图案A的尺寸相匹配，所述第二光源401射出的光束的尺寸与图案B的尺寸相匹配。所述第一光源/第二光源/第一光源和第二光源所发出的光束投射在所述遮光板上，至少投射出图案A的形状/图案B的形状/图案A和图案B共同组成的形状。需要投影出不同的形状时，只需转动遮光板2使对应的图案与对应的光源相对并点亮光源即可。
其中，遮光板2上设有驱动盘体转动或摆动使图案片选择性地处于有效遮挡光束的位置和不遮挡光束的位置的驱动装置。这样设置便于精确驱动遮光板2转动到指定位置，以切换与激光光源3及LED光源4对应的图案，进而投影出不同的光束形状及图案形状。作为优选，本实施例采用的第一光源301为激光光源3，所述第二光源401为LED光源4。当激光光源3发光时，激光照亮图案A，呈现出图案A的形状；当LED光源4发光时，LED光会同时照亮图案A及图案 B，因此能呈现出图案A和图案B共同组成的形状；当激光光源3及LED光源4一起发光时，激光和LED光会同时照亮图案A及图案B，因此也能呈现出图案A和图案B共同组成的形状。
如图5所示，还包括沿第一光源301、第二光源401的主光轴D依次设置的第一导光组件8、第二导光组件9及多个光学镜头组件，第一导光组件8设置在激光光源3的出光面，第二导光组件9设置在LED光源4的出光面上，且LED光源4在第一导光组件8与第二导光组件9之间，LED光源4及第二导光组件9正对第一导光组件8的位置上设有开口41，激光光源3的光穿射第一导光组件8后或LED光源4的光穿射第二导光组件9后依次经过多个光学镜头组件形成光束出光模式或图案出光模式。
第一导光组件8上包括收光透镜组件81、嵌设于开口41内的汇聚透镜组件82和位于收光透镜组件81与汇聚透镜组件82之间的荧光粉盘83，荧光粉盘83内放置有用于激发激光的荧光粉。激光光源3发射的激光激发荧光粉产生白光，LED光源4发射的光从第二导光组件9穿射出。
本实施例中，从第一导光组件8穿射出的光与第二导光组件9穿射出的光具有相同的焦点。
本实施例中，只打开激光光源3，激光光源3发射的激光传输到第一导光组件8上并激发荧光粉产生白光，从第一导光组件8穿射出的光依次经过多个光学镜头组件后，即可形成光束出光模式，显示出图案A的形状；只打开LED光源4，LED光源4发射的光从第二导光组件9穿射出并依次经过多个光学镜头组件后，即可形成图案出光模式，因图案A的形状嵌套在图案B中，所以显示出图案A和图案B的形状。同时打开激光光源3和LED光源4，则光束出光模式和图案出光模式同时启动，也能显示出图案A和图案B的形状。
其中，多个光学镜头组件为依次连接的第一光学镜头组件5、第二光学镜头组件6及第三光学镜头组件7；激光光源3的光穿射第一导光组件8后或LED光源4的光穿射第二导光组件9后依次经过第一光学镜头组件5、第二光学镜头组件6及第三光学镜头组件7形成光束出光模式或图案出光模式。
另外，激光光源3的出光孔直径是L，LED光源4的出光孔的直径是n×L，有n＞1。本实施例的投光步骤包括：
(1)在投光装置上设置遮光板2，遮光板2能选择性地阻挡光源所发出的光束，遮光板上至少设有两个图案；
(2)在遮光板2的背后设置至少两种光源，每种光源所发出的光束投射在遮光板2上时，能呈现出与之对应的图案的形状；
(3)将遮光板2上的图案设计成呈左右/上下/嵌套分布，在遮光板的背后设置对应图案的光源，且光源呈左右/上下/嵌套设置，光源所发出的光束投射在遮光板上，至少能呈现出与之对应图案的形状；
因为遮光板2上设有若干个图案区域1，而每个图案区域1的后面均设有第一光源3和第二光源4，所以投射在舞台上的图案能呈现出多种多样的形状。另外，通过转动装置使遮光板2沿顺时针或逆时针转动，则投射在舞台上的图案也会转动起来，渲染舞台的气氛。通过设置光源的颜色还能使投射在舞台上的图案呈现多种颜色。
实施例2
如图2的第二种情况所示，本实施例与实施例1不同的是，第一光源302/第二光源402所发出光束的形状与对应的图案A/图案B的形状相匹配，只打开第一光源302，第一光源302所发出的光束照射在图案A上，只呈现出图案A的形状，只打开第二光源402，第二光源402所发出的光束照射在图案B上，只能呈现出图案B的形状，同时打开第一光源302和第二光源402，则同时能呈现出图案A和图案B的形状。
实施例3
如图2的第三种情况所示，本实施例与实施例1不同的是，遮光板2上的图案为两个且呈左右分布，遮光板2的背后设有对应图案的两种光源，且两种光源呈左右设置，两种光源分别为第一光源303和第二光源403，两个图案分别为图案A和图案B，第一光源303对应图案A，第二光源403对应图案B，只打开第一光源303，第一光源303所发出的光束照射在图案A上，只呈现出图案A的形状，只打开第二光源403，第二光源403所发出的光束照射在图案B上，只呈现出图案B的形状，第一光源303和第二光源403同时打开，则同时能呈现出图案A和图案B的形状。
