为了便于理解，本申请对下文涉及的一些定义进行解释。
光通量：发光体出射的可见光总量。
照度：单位面积入射光的光量。
在目前主流灯具中，随着发光二极管(Light Emitting Diode，LED)成本的降低和效率的提升，大功率的LED光源在照明领域得到大规模的应用。大功率的LED光源一般由多个LED芯片以及LED芯片阵列按照一定距离组合而成，因此大功率LED光源光通量比较大，但其缺点在于，在灯具镜头输出时LED的照度较低。
而在舞台照明等专业的照明场景中，通常采用大功率激光作为照明光源。大功率激光输出的照度非常高，激光所输出的照度是目前LED技术难以比拟的。
有鉴于此，本申请提供一种照明装置，该照明装置可以将激光光源等小角度光源和LED光源组合为混合光源，使得照明装置兼顾照度和光通量的要求，照明装置可以应用于多种需求的照明场景中，照明场景包括但不限于居家、会客、舞台等。
请参见图1，图1是本申请提供的照明装置的一实施例的结构示意图。如图1所示，本申请实施例的照明装置包括混合光源10、第一会聚元件8、调节机构11、聚光机构13和光栏9。
混合光源10用于产生光线，其中，混合光源10包括但不局限于以发光二极管(LED)为发光体的光源、利用氙气放电而发光的电光源、以荧光物质作为发光材料的光源、以有机发光二极体(OrganicLight-Emitting Diode，OLED)为发光体的光源等，混合光源10至少包括具有高光通量的第一光源102和具有高照度的第二光源100，第一光源102可以是LED或OLED光源，第二光源100可以是短弧氙灯、超高压汞灯等高强度气体放电光源，第二光源100也可以为激光光源，第一光源102和第二光源100的结合使得照明装置能够兼具高照度、高光通量的特点。
第一会聚元件8设置于第一光线和第二光线的光路上，用于将混合光源10发射的光线会聚在光栏9或者汇聚在照明装置的输出面上。聚光机构13设置于调节机构11上，调节机构11用于调节聚光机构13的位置，以使聚光机构13位于经过第一会聚元件8出射的第二光线的光路上或位于经过第一会聚元件8出射的第一光线的光路外；第一光线经过第一会聚元件8传输至光栏9，或者，第二光线经过第一会聚元件8和聚光机构13传输至光栏9。
具体的，第一会聚元件8位于混合光源10与光栏9之间，第一光源102位于第二光源100和第一会聚元件8之间，调节机构11、聚光机构13位于第一会聚元件8与光栏9之间，调节机构11用于调整聚光机构13的位置，使其位于光线的光路上或者位于光线的光路外。可以理解的，在一实施方式中，混合光源10发射的光线的光路依次设置有第一会聚元件8、聚光机构13、光栏9；在另一实施方式中，混合光源10发射的光线的光路依次设置有第一会聚元件8、光栏9。根据照明装置的照明用途等，可以通过调节机构11调整聚光机构13的位置，使其位于光线的光路上，提高照明装置输出的光斑亮度；在照明装置没有亮度需求时，也可以调整聚光机构13使其位于光线的光路外。
进一步地，照明装置可以至少包括三个照明模式，第一照明模式为使用第一光源102作为主光源的照明模式，此时，通过调节机构11调整聚光机构13的位置使其位于第一光线的光路外，第一光线不经过聚光机构13而直接投射到光栏9上，以输出高光通量的照明光；第二照明模式为使用第二光源100作为主光源的照明模式，此时，通过调节机构11调整聚光机构13的位置使其位于第二光线的光路上，第二光线经过聚光机构13和第一会聚元件8聚焦到光栏9上，形成高照度高强度的照明光；第三照明模式为第一光源102和第二光源100均作为主光源的照明模式，此时，经过第一会聚元件8出射的第一光线的光路和经过第一会聚元件8出射的第二光线的光路不重合，通过调节机构11调整聚光机构13的位置，使其位于第一光线的光路外并位于第二光线的光路上，以形成高光通量、高强度的照明光。用户在使用照明装置时，可以根据照明需求选择不同的照明模式，提高用户的使用体验。
在本申请实施例中，照明装置使用混合光源10产生光线，调节机构11将聚光机构13调至第一会聚元件8的第一光线的光路上或第二光线的光路外，使得光线经过第一会聚元件8后聚焦到光栏9上并形成具有高光通量和高照度的照明光斑，使得该照明装置能够满足高照度和高光通量输出的需求，有利于照明装置的广泛应用。
在一实施例中，第一光源102可以为LED发光板，第一光线可以为LED光线。
照明装置还包括匀光机构7，匀光机构7设置于第一光源102和第一会聚元件8之间，匀光机构7包括至少两列的透镜阵列，每列透镜阵列由若干小单元复眼透镜组成，第一列透镜阵列中的各个小单元透镜的焦点与第二列透镜阵列中对应的小单元透镜的中心重合，两列小单元透镜的光轴互相平行。
第一列透镜阵列用于将第一光源102形成的宽光束分为多个细光束，从第一列透镜阵列出射的细光束入射至第二列透镜阵列，第二列透镜阵列的每个小单元透镜将细光束重叠成像于照明面上，每个细光束的微小不均匀性由于处于对称位置细光束的相互叠加使细光束的微小不均匀性获得补偿，使得第二列透镜阵列在输出面形成的光斑的每一点均受到第一光源102的所有点发出的光线照射，从而起到均匀光斑的效果，以提高照明装置出光的视觉效果。
可选的，在使用第一光源102作为照明装置的主光源时，调节机构11用于调节聚光机构13位于经过第一会聚元件8的第一光线的光路外，以使第一光线依次经过匀光机构7和第一会聚元件8传输至光栏9。
可选的，调节机构11包括调节旋钮12和旋转轴14，调节旋钮12固定于旋转轴14上，调节旋钮12用于带动旋转轴14旋转，以使聚光机构13沿旋转轴14的延伸方向移动。
具体的，调节旋钮12用于带动旋转轴14旋转并调节聚光机构13在旋转轴14上的位置，以使得聚光机构13位于第二光线的光路上或者位于第一光线的光路外。在可选的实施方式中，聚光机构13设置于旋转轴14上并可沿旋转轴14上下滑动，第一光线和第二光线的光路部分重合，可以通过调节旋钮12将聚光机构13沿旋转轴14的延伸方向移动，以使得聚光机构13切入第二光线的光路或者切出第一光线的光路。
可选的，聚光机构13为具有聚光效果的凸透镜，聚光机构13沿旋转轴14的延伸方向移动，旋转轴14的延伸方向与聚光机构13的光轴方向垂直设置，以使得混合光源10产生的光线能够经第一会聚元件8后进入聚光机构13或者直接传输至光栏9。
在一实施例中，第一光源102为LED光源，照明装置包括用于收光的照明镜头，混合光源10产生的光线经照明镜头后照射至外部环境中，以达到照明的效果。照明镜头上形成有一输出面，第一光线经过光栏9后照射至输出面，以在输出面上形成有第二光斑。
第一光线照射至光栏9并在光栏9上形成有第一光斑，第二光斑的形状与第一光斑的形状不同，示例性的，第一光源102产生的第一光线在光栏9上形成的第一光斑为正六边形时，第一光线经光栏9后照射至输出面时形成的第二光斑的形状可以为圆形。光栏9可以改变光斑的形状，以提高照明装置出光的视觉效果，提高用户的使用体验。
具体的，第一光源102的发光芯片形成的阵列形状不同导致第一光斑的形状多样。例如，在使用第一光源102作为照明装置的主光源时，光线在光栏9上形成的第一光斑的形状可以为六边形，此时，光线经光栏9后在输出面上形成的第二光斑的形状可以为圆形，提高照明装置输出的照明光斑的美观度。
请参见图2，图2是本申请提供的照明装置的另一实施例的结构示意图。如图2所示，在本实施例中，混合光源10的第一光源102为LED发光板，第二光源100为激光光源，第二光线为激光光线。
具体的，LED发光板包括基板和发光芯片，其中，基板的形状包括但不局限于圆形、多边形等，基板的中心位置处设置有一通孔，第二光源100发射的第二光线通过该通孔传输至光栏9，发光芯片的阵列排布在基板上通孔以外的其他位置。
其中，照明装置进一步包括第二会聚元件4，第二会聚元件4设置于第二光源100与第一光源102之间，第二会聚元件4用于将第二光源100发射的第二光线会聚至通孔处，第二光线穿过通孔并传输至光栏9。
可选的，照明装置包括波长转换元件5，设置于通孔，用于将第一波长的第二光线转换为第二波长的第二光线。
具体的，波长转换元件5通过通孔设置于基板，波长转换元件5可以为荧光滤光片，用于将第一波长的第二光线转换为第二波长的第二光线，以改变第二光线的颜色和波长范围，使其适用于不同的照明场景。其中，荧光滤光片包括但不局限于黄光荧光片、绿光荧光片或红光荧光片，根据实际使用需求可以选择不同滤光范围或转换范围的波长转换元件5，在此对波长转换元件5的滤光范围不做具体限定。
可选的，调节机构11用于调节聚光机构13位于经过第一会聚元件8的第二光线的光路上，以使第二光线依次经过第一会聚元件8和聚光机构13传输至光栏9。
具体的，在使用第二光源100作为照明装置的主光源时，调节机构11用于调节聚光机构13位于经过第一会聚元件8的第一光线的光路上。由于激光光线为单个发光点，在使用激光光线进行照明时无需使用匀光元件进行散射处理；匀光机构7具有多个匀光板，例如图2所示，在第一匀光板71和第二匀光板72并列设置时，第一匀光板71和第二匀光板72之间设有间隙，第二光源100发射的第二光线在经过通孔后从第一匀光板71和第二匀光板72的间隙穿过并依次经过第一会聚元件8和聚光机构13传输至光栏9。
进一步地，在其他实施方式中，在使用第二光源100作为照明装置的主光源时，调节机构11还可以用于调节聚光机构13位于经过第一会聚元件8的第一光线的光路外。此时，照明装置可以设置有多个亮度模式，例如，在调节机构11调节聚光机构13位于经过第一会聚元件8的第一光线的光路上时，光栏9上形成的照明光斑的照度更高，处于第一亮度模式；在调节机构11调节聚光机构13位于经过第一会聚元件8的第一光线的光路外时，光栏9上形成的照明光斑的照度较低，处于第二亮度模式，使得用户在使用照明装置时可以根据照明需求选择多种亮度，提高用户的使用体验。
可选的，混合光源10包括准直机构101，准直机构101设置于第一光源102与第一会聚元件8之间，准直机构101的焦平面在第一光线和/或第二光线的光路上，准直机构101用于调整第一光线和/或第二光线的发散角。
具体的，准直机构101设置于第一光源102远离第二光源100的一侧，或者，准直机构101设置于第一光源102出射的第一光线的光路上。准直机构101用于收集第一光源102发出的第一光线并调整第一光线的发散角，发散的第一光线经过准直机构101后变成平行的第一光线；第二光源100发射的第二光线经过通孔后聚焦到准直机构101的焦平面上，准直机构101调整第二光线的发散角，提高照明装置的照明效率。
在一实施例中，照明装置还可以设置有第三照明模式，第三照明模式可以同时使用第一光源102和第二光源100作为照明光源，此时，可以根据使用控制调节机构11调节聚光机构13的位置。照明装置可以根据照明光源的选择、聚焦强度的选择等对照明模式进行配置，以满足用户对于不同强度、不同光通量的照明设备的需求，提高用户的使用体验。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
