Description

发光二极管舞台投射灯
技术领域
本实用新型涉及一种应用在舞台上的投射灯，尤其涉及一种采用发光二极管(LED)为光源的舞台投射灯结构。
背景技术
现代化剧场中面光、投光位置不仅安放聚光灯，还有一些成像效果灯具以及数字换色器等器材混合使用，有些剧场的面光灯光器材选用聚光、成像、变焦灯具混合使用并配加换色器，使灯光的表现能力得到提高。目前发光二极管运用在舞台上都是用作背景光源，用在背景上面，正在替代现有的灯饰；为了解决柔光问题，替换大功率的几何图形投射灯，有必要采用新的节能光源。
实用新型内容
针对现有技术存在的问题，本实用新型所要解决的技术问题是要提供一种能耗低、工作稳定可靠的发光二极管(LED)舞台投射灯，为了解决用发光二极管来做投射图案，采用程序控制发光二极管发光显示光亮，在发光二极管(LED)前面加上菲涅尔透镜，来对此光源投射，使其能够投射出一定距离的几何图形，其使用寿命长、可靠性高。
为达上述目的，本实用新型的发光二极管舞台投射灯结构，采用以下的技术方案：
一种发光二极管舞台投射灯，包含有机身，机身上设有程序控制电路板，程序控制电路板电连接发光二极管板，机身上设有发光二极管板，机身前端设有菲涅尔透镜。
进一步地，所述发光二极管板正前方设有菲涅尔透镜；
进一步地，所述机身上设有开关电源，开关电源电连接程序控制电路板；
上述的开关电源设有整流电路。
发光二极管在没有使用菲涅尔透镜进行投射的情况下，只能显示一种光亮和一些本质大小的图形，本实用新型现加上此菲涅尔透镜后可以将其远距离投射，并使图案本身变大；在烟雾机使用下可以很明显的看到所投射的光线。本实用新型解决用发光二极管(LED)来做投射图案，采用加菲涅尔透镜结构的新型舞台投射灯，菲涅尔透镜是用压克力俗称有机玻璃(即PMMA)材料所做成的一种光环镜，成份是聚甲基丙稀酸甲酯做成的，用来对发光二极管(LED)投射使其能够投射出一定距离的几何图形，本实用新型结构简单，工作稳定可靠。
附图说明
图1是本实用新型实施例的结构示意图；
图2是本实用新型实施例的工作示意图。
具体实施方式
为能进一步了解本实用新型的特征、技术手段以及所达到的具体目的、功能，下面结合附图与具体实施方式对本实用新型作进一步详细描述。
本实用新型相关结构主要包括以下零部件(或装置)：开关电源1、程序控制电路板2、发光二极管板3、菲涅尔透镜4、二极管光源5、机身6、投射光线7。
本实用新型在机身6上设有程序控制电路板2，程序控制电路板2电连接发光二极管板3，机身6上设有发光二极管板3，机身6前端设有菲涅尔透镜4。
发光二极管板3正前方设有菲涅尔透镜4，机身6上设有开关电源1，开关电源1电连接程序控制电路板2，开关电源1设有整流电路。
电源进入开关电源1进行整流，后再将电流进入程序控制电路板2，经过程序控制电路板2控制、处理的电信号进入发光二极管板3，使发光二极管(LED)进行发出不同的色度光亮，经过菲涅尔透镜4进行有效的投射。
菲涅尔透镜又称阶梯镜，即有“阶梯”形不连续表面组成的透镜，“阶梯”由一系列同心圆环状带区构成，又称环带透镜。
参见附图2，发光二极管板3是发光二极管(LED)组成的灯板，二极管光源5为发光二极管所发的光源，经过菲涅尔透镜4成为有效的投射光线7，并投射成图案灯，此光线的轮廓柔和。
以上所举实施例仅用为方便举例说明本实用新型，并非对本实用新型作任何形式上的限制，任何所属技术领域中具有通常知识者，若在不脱离本实用新型所提技术特征的范围内，利用本实用新型所揭示技术内容所作出局部更动或修饰的等效实施例，并且未脱离本实用新型的技术特征内容，均仍属于本实用新型技术特征的范围内。
