混光器16包括有导光体161和导光筒162，导光筒162连接在导光体161前侧。
导光体161一侧间隔地设置有两个以上的导光柱1611，导光柱1611朝向灯珠15延伸。导光柱1611的数量与灯珠15的数量一致，布置方式一致，从而使得每颗灯珠15的前侧都对应有一根导光柱1611，每根导光柱1611用于将对应的灯珠15的光导出。每根导光柱1611对应布置的一个灯珠15的正前方。导光柱1611可以与灯珠15接触，也可以与灯珠15间隔一定距离。
导光体161的另一端具有一个导光端子1612，其朝向导光筒162延伸，并嵌入在导光筒162的后端中。导光端子412用于将各导光柱1611传来光混在一起，并传给导光筒162，最后由导光筒162将混合后的光传导出。
一部分光会经导光筒162的通孔直接传导出，一部分光会经导光筒162的筒壁传导出。从导光筒162传导出的光为两个以上的灯珠15的混合光，可以是颜色混合后的光，也可以是亮度混合后的光。
由此，本发明提供的灯体，通过在电路板上安装两个以上的灯珠，并配置混光器，可以将各灯珠发出的光混在一起，一方面可以提高光照 亮度，另一方面可以混合光的颜色，以达到混光效果，满足不同的照明和投影需求。
在其中一个实施例中，如图4所示，导光筒162中具有导光隔板1621，导光端子1612与导光隔板1621接触，使得从导光端子1612传导来的部分光经导光隔板1621传导至导光筒162的筒壁，再由导光筒162的筒壁传导出，还是得一部分光透过导光隔板1621从导光筒162的通孔直接传导出。
在其中一个实施例中，如图5-7所示，电路板14面向导热件13的一侧间隔地设置有导电部141和传热部142。
导热件13包括导热件基部131和设置在导热件基部131上的导热件凸起132，导热件凸起132与传热部142接触。
在导热件基部131上面向电路板14的一侧设置有绝缘隔热层133。
在绝缘隔热层133上设置有导电层134，在导电层134上设置有保护涂层135。
导电层134至少部分穿过保护涂层135，并与导电部141接触。
导电部141可以为导电安装盘，传热部142可以为传热安装盘，传热部142位于导电部141的中间，传热部142与导电部141间隔分离。
导电部141用于导通电路板14的电路，传热部142用于将电路板14上的热量传导出。
为了实现电路板14的导电路径与散热路径分离，采用如下方式布置：
导热件13包括导热件基部131和导热件凸起132，导热件凸起132一体设置在导热件基部131的中部。组装时，导热件凸起132与传热部142接触，使得灯珠15发出的热量可经电路板14、传热部142、导热件凸起132、导热件基部131传导至散热器12进行散热。
在导热件基部131的表面设置有至少一层绝缘隔热层133。绝缘隔热层133既具有绝缘功能，也具有隔热功能。
在绝缘隔热层133上布置有导电层134，导电层134可以为印刷电路层，也可以为导线层。导电层134与外界电路或电池连接。
在导电层134上涂覆有保护涂层135。保护涂层135可以为白油层。
导电层134具有凸起部分，组装时，导电层134的凸起部分穿过保护 涂层135，并与导电部141接触，导电层134中的电流可经凸起部分、导电部141传递给电路板14，从而实现导电。
绝缘隔热层133一方面可以起到绝缘作用，避免导电层134漏电；绝缘隔热层133另一方面还起到隔热作用，避免导热件基部131中的热量传导至导电层134影响导电性能。通过在导电层134与导热件基部131之间设置绝缘隔热层133，使得电路板14的散热路径与导电路径分离，相互不影响，提高了散热、导电性能。
绝缘隔热层133可以为橡胶层，其不仅具有绝缘效果还具有隔热效果。
在其中一个实施例中，如图1所示，导热件13面向散热器12的一侧具有导热件插接端130，散热器12的前端具有散热器插槽。导热件插接端130嵌入在散热器插槽内。
热件插接端130一体成型在导热件14的后端，散热器插槽设置在散热器12的前端。导热件插接端130从前向后嵌入在散热器插槽内，一方面提高了导热件13与散热器12的连接稳定性，另一方面还利于将导热件13上的热量快速传至散热器12内，以实现更好的散热效果。
如图8和图18所示，本发明一实施例提供的一种灯具，包括镜头2和前述任一实施例中所描述的灯体1。镜头2可拆卸地安装在灯筒11的前端上。

在灯筒11的前端安装有透镜固定环18，灯筒透镜17安装在透镜固定环18中。透镜固定环18通过螺钉181安装在灯筒11的前端。胶片托架环4通过螺钉连接在透镜固定环18的前侧。
连接环5通过螺钉连接在胶片托架环4的前方，第一镜筒211与连接环5通过螺纹或卡扣连接，使得第一镜筒211与连接环5可拆卸连接，方便更换第一镜头21。
优选地，在灯筒11内间隔设置有两片灯筒透镜17，在第一镜筒211中间隔地设置有两片第一透镜210。
在使用时，胶片安装在胶片托架41上，胶片托架41插入在开口槽40中。灯珠15发出的光经混光器16混光后，经灯筒透镜17后照射到胶片上，光再经第一透镜210投射出，从而将胶片上的图案信息投射出。在该过程中，可以滑动第一透镜210，调节其与胶片之间的距离，进行调焦，使得图案信息可以清晰的投射出。
本发明提供的灯具，通过在灯体的前端配置第一镜头，可以实现精确调焦，提高投影的清晰度。

第一卡环7上间隔地设置有两个以上的卡爪72，第二卡环8上相应地设置有卡槽。当朝向第一方向转动第一镜头21，并带动第二卡环8转动时，可以使得第二卡环8的卡槽与第一卡环7的卡爪72卡接，将第一镜头21安装在连接环5上；当朝向与第一方向相反的第二方向转动第一镜头21，并带动第二卡环8转动时，可以使得卡槽与卡爪72脱离，将第一镜头21从连接环5上拆下。
在第一卡环7上设置有第一定位孔71，在第二卡环8上设置有第二定位孔81，随着第一镜头21的转动，第二定位孔81可以与第一定位孔71对齐，也可以错开。
定位销51设置在连接环5中，在连接环5上设置有朝向第二卡环8延伸的定位柱53，定位销51的后侧具有滑槽512，定位柱53插入在滑槽512内，两者间隙配合，使得定位销51可以在定位柱53上前后滑动。定位销51的前端可滑动地配置在第一定位孔71中。定位销51的直径小于第一定位孔71的直径，也小于第二定位孔81的直径。
定位销驱动弹簧54套在定位柱53上，其预紧在定位销51与定位柱53的后端之间。定位销驱动弹簧54用于驱动定位销51朝向第二卡环8侧移动，以使的定位销51的前端插入在第二定位孔81中，从而将第一卡环7和第二卡环8锁定在一起，第二卡环8不能相对第一卡环7转动，两者不能拆开。
驱动按钮52设置在连接环5上，其用于驱动定位销51后移从第二定位孔81中移出，此时第二卡环8可以相对于第一卡环7转动，可以将第一镜头21从连接环5上拆卸下来。

当按压按钮部头部5201时，触头521朝向凸起部斜面5111移动，并与凸起部斜面5111接触，从而推动定位销51向后移动，使得定位销51的前端从第二定位孔81中脱离。此时第二卡环8可以相对于第一卡环7转动，可以将第一镜头21从连接环5上拆卸下来。
当释放作用在按钮部头部5201上的力时，在柱体部驱动弹簧55作用下，触头521离开凸起部斜面5111，在定位销驱动弹簧54的作用下，定位销51前移并插入在第二定位孔81中。此时，第二卡环8不能相对第一卡环7转动，两者不能拆开，第一镜头21不能从连接环5上拆卸下来。

调焦镜头225可以与第二镜筒221螺纹连接，以能够相对于第二镜筒221前后移动，调节调焦镜头225与胶片224之间的距离，进行焦距调节。当然，调焦镜头225也可以自身能够伸缩，例如采用两个螺纹连接套筒，调焦镜片安装在套筒中，两个套筒相对旋转，即可调节调焦镜片与胶片24之间的距离，进行焦距调节。
灯珠15发出的光，经混光器16混光后，投射到第二透镜220，再经第二透镜220聚焦后投射到胶片224上，再经调焦镜头225投射出，从而可以将胶片224上的图案信息投射出。
当胶片224投射出的图案信息角度不满足要求时，可以转动第二镜筒221，调节胶片224的角度，以使得投射出的图案信息对正，方便操作。
