背景技术
投影灯，又称成像灯，是一种可以将图像或文字投射到地面或者幕墙上的电器设备。投影灯广泛应用于教学、实验测试及会议等领域当中。
相关技术的投影灯存在以下缺陷：

其次，相关的投影灯的光源大多数为常规发散光源，并非为点光源，易造成投影清晰度下降，甚至失真的情况。

具体实施方式
下面结合附图并通过实施例来说明本公开的技术方案。
在一实施例中，本公开实施例提供了一种投影灯组件，如图1所示，该投影灯组件包括：箱体1、前透镜组件2、镜头组件3、后透镜组件4以及位移调节组件5。
在一实施例中，前透镜组件2滑动设置于箱体1内部，镜头组件3位于前透镜组件2的前方，镜头组件3可拆卸连接于箱体1，且镜头组件3上刻印有图像31。后透镜组件4位于前透镜组件2的后方并滑动设置于箱体1内部。位移调节组件5设置于箱体1内部，位移调节组件5分别连接于前透镜组件2和后透镜组件4，并能够调节前透镜组件2和后透镜组件4之间的中心距。
在一实施例中，本公开实施例提供了一种投影灯，如图2和图3所示，该投影灯包括：箱体1、滑动设置于箱体1内部的前透镜组件2、位于前透镜组件2的前方的镜头组件3、位于前透镜组件2的后方的后透镜组件4、设置于箱体1内部的位移调节组件5及光源组件6，其中，镜头组件3可拆卸连接于箱体1，且镜头组件3上刻印有图像31。后透镜组件4位于前透镜组件2的后方并滑动设置于箱体1内部，且位移调节组件5分别连接于前透镜组件2和后透镜组件4，并能够调节两者之间的中心距。另外，光源组件6设置于箱体1上并位于后透镜组件4的后方，光源组件6发出的光线穿设后透镜组件4和前透镜组件2，以将镜头组件3上的图像31成像在屏幕7上。
在一实施例中，前方和后方为在同一水平参考方向上用于区分组件位置的描述，在不同的参考方向上，也可以用下方和上方进行区分描述。以投影灯在水平方向上或者接近水平方向上进行投影为例，光源组件6发出的光线依次穿设后透镜组件4和前透镜组件2，即发出光线的光源组件6在后方，光线依次穿设后透镜组件4和前透镜组件2后从前方的镜头组件3透射出去。
本公开实施例提供了一种投影灯，在箱体1内部从后到前依次设置有光源组件6、后透镜组件4、前透镜组件2及镜头组件3，使得光源组件6发出的光线穿设后透镜组件4和前透镜组件2，以将镜头组件3上的图像31成像在屏幕7上。采用此种方式，可以将非点光源发出的发散的光线，经过后透镜组件4和前透镜组件2的两次聚集之后，可以将图像31放大并投影在屏幕7上。
与相关技术中投影光仅进行单次投影相比，本公开实施例提供的投影灯组件汇聚光线效果明显，解决了非点光源成像失真的问题，提高了投影清晰度；同时，无需加大光的照射功率，就能保证良好的成像效果，减少了投影灯的能源消耗，进而提高了使用寿命；另外，避免了其他的补偿电路对成像质量做后期技术处理的情况，从而节约了能源，且降低了成本投入。
而且，该投影灯组件中的位移调节组件5分别连接于前透镜组件2和后透镜组件4，并能够调节两者之间的中心距，方便用户调整投影灯的放大倍数和清晰程度，以满足所需的成像效果。
另外，采用将图像31直接打印在镜头组件3上，与相关投影灯中的独立的字幕或者图像结构相比，简化了结构，节省了占用空间；且镜头组件3可拆卸 连接于箱体1，操作简单，便于及时更换和维护。
如图2和图3所示，光源组件6包括设置于箱体1上的光源底板61及设置于光源底板61上的投影光源62。其中，光源底板61和镜头组件3分别设置在箱体1两个相对的侧面上，且前透镜组件2和后透镜组件4位于光源底板61和镜头组件3之间，使得普通的发散光源发射的光线经过前透镜组件2和后透镜组件4的折射和聚集，将镜头组件3上的图像31投影在屏幕7上。采用此种方式，无需点光源，普通光源就能实现，降低了对光源的要求及制作成本，且提高了光源的通用性。
在一实施例中，投影光源62为传统灯泡光源、发光二极管(Light Emitting Diode，LED)光源或者激光光源，但并不限于此。
如图2和图3所示，前透镜组件2包括前固定架21以及设置于前固定架21内部的前凸透镜22，前固定架21起到了对前凸透镜22的固定作用，后透镜组件4包括后固定架41以及设置于后固定架41内部的后凸透镜42，后固定架41起到了对后凸透镜42的固定作用，并且前凸透镜22的宽度大于后凸透镜42的宽度。
如图2和图3所示，为了便于用户能够对前透镜组件2和后透镜组件4进行调节，位移调节组件5包括设置于箱体1上的驱动件和设置于箱体1内部的导轨(图中未示出)，前透镜组件2和后透镜组件4均设置于驱动件的输出端上且均与导轨滑动设置，驱动件能够驱动前透镜组件2和后透镜组件4沿导轨前后移动。
在一实施例中，为了保证成像质量，光源组件6的中心线、导轨的中心线、前透镜组件2的中心线和后透镜组件4的中心线在同一条直线上，当前透镜组件2和后透镜组件4在驱动件的驱动下沿导轨移动过程中，能够始终确保前透镜组件2的中心线和后透镜组件4的中心线共线。
在一实施例中，该驱动件为调节电机51，调节电机51的传动丝杠52为正反牙丝杠，正反牙丝杠的两端分别穿设于前固定架21的底部和后固定架41的底部，使得调节电机51能够驱动前透镜组件2和后透镜组件4向方向相反的方向移动，即前透镜组件2和后透镜组件4同时向靠近或远离正反牙丝杠的中部的方向移动；但不限于此，前透镜组件2和后透镜组件4亦可以同向运动。
本实施例提供的投影灯的工作原理如下；
当投影光源62发射的光线为发散光线，先经过后凸透镜42将光线第一次折射聚集，例如光线的夹角由170°变成150°；然后经前凸透镜22将该光线第二次折射聚集，光线的夹角由150°变成100°并将镜头组件3上的图像31放大并投影于屏幕7上，通过位移调节组件5调节后凸透镜42和前凸透镜22之间的中心距，调节放大倍数和清晰度；
当投影光源62发射的光线与后凸透镜42的中心线平行时，将镜头组件3上的图像31等大投影于屏幕7。
