具体实施例
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本发明。
如图1-图7所示，根据本发明实施例的照明装置10可以为像素大灯，照明装置10包括：壳体1、光源30、DMD芯片40和反射镜7、分流结构2和送风装置。反射镜7可以为平面镜，光源30、DMD芯片40和反射镜7分别设置在壳体1内，DMD芯片40和光源30可以位于壳体1内的第一侧，壳体1内的第一侧可以是壳体1内的后侧，DMD芯片40与光源30在壳体1内的第一侧彼此相邻地间隔开布置，反射镜7位于壳体1内的与第一侧相对的第二侧，壳体1内的第一侧可以是壳体1内的前侧，光源30发出的光通过反射镜7的反射后射向DMD芯片40，然后光在DMD芯片40的作用下反射从镜头组件9射出照明装置10。
其中，本申请通过在壳体1内设置反射镜7，且DMD芯片40和光源30设置于壳体1内的第一侧，反射镜7设置于壳体1内的第二侧，照明装置10的散热结构只需设置于壳体1的设置有DMD芯片40和光源30的区域，与现有技术相比，本申请不需要在壳体1的设置有反射镜7的区域设置散热结构，能够降低散热结构的布置数量，可以减小照明装置10的体积，从而可以减小照明装置10的安装空间，并且，由于散热结构的布置数量减少，也可以降低照明装置10的生产成本。
壳体1的内壁面上形成有光源安装区域13和DMD安装区域14，光源30设置在壳体1内且位于光源安装区域13，DMD芯片设置在壳体1内且位于DMD安装区域14，壳体1的外壁面上形成有光源散热区域11和DMD散热区域12，光源散热区域11与光源安装区域13对应，DMD散热区域12与DMD安装区域14对应，DMD芯片通过DMD散热区域12散热，光源7通过光源散热区域11散热。送风装置设置在壳体1之外，分流结构2设置在壳体1的外壁面上，分流结构2处在光源散热区域11与DMD散热区域12之间，分流结构2用于引导风分别吹向光源散热区域11和DMD散热区域12，送风装置吹出的经由分流结构2引导后分别吹向光源散热区域11和DMD散热区域12。
当照明装置10工作时，光源30和DMD芯片40产生热量，然后DMD芯片40将热量传递给DMD散热区域12，光源30将热量传递给光源散热区域11，同时，送风装置向分流结构2吹风，在分流结构2的作用下，能够将 一部分风引导流向DMD散热区域12，也能够将另一部分风引导流向光源散热区域11，然后流向DMD散热区域12的风会对DMD散热区域12进行散热，流向光源散热区域11的风会对光源散热区域11进行散热，使光源散热区域11和DMD散热区域12上的热量散出，从而使光源散热区域11和DMD散热区域12的温度降低，这样设置能够将照明装置10产生的热量散出，可以避免照明装置10过热，从而可以保证照明装置10的工作可靠性，进而可以延长照明装置10的使用寿命，并且，本申请的分流结构2的结构简单，占用体积小，可以简化照明装置10的结构，也可以减小照明装置10占用空间，从而可以使照明装置10方便安装，也可以降低照明装置10的生产成本。
同时，通过使分流结构2间隔在光源散热区域11与DMD散热区域12之间，能够避免光源散热区域11的热风被吹到DMD散热区域12，也能够避免DMD散热区域12的热风被吹到光源散热区域11，可以保证使光源散热区域11和DMD散热区域12散热完全，从而可以保证光源30和DMD芯片40的工作可靠性，进而可以光源30和DMD芯片40的使用寿命。另外，通过设置送风装置，能够将风快速吹向分流结构2，可以提升对照明装置10的散热效率。
如图4所示，照明装置10还包括：热量传导断桥结构6，热量传导断桥结构6设置在光源安装区域13和DMD安装区域14之间，而且热量传导断桥结构6用于至少部分地阻断光源安装区域13向DMD安装区域14传导的热量，通过设置热量传导断桥结构6，能够降低光源安装区域13的热量传导至DMD安装区域14的量，也能够降低DMD安装区域14的热量传导至光源安装区域13的量，可以保证光源30和DMD芯片40的工作可靠性，从而可以延长光源30和DMD芯片40的使用寿命。
由此，通过设置分流结构2以及送风装置，能够使一部分风对光源30散热，也能够使另一部分风对DMD芯片40散热，可以避免照明装置10过热，并且，也能够避免光源散热区域11的热风被吹到DMD散热区域12，还能够避免DMD散热区域12的热风被吹到光源散热区域11，可以保证DMD芯片40的工作可靠性，同时，本申请的照明装置10结构简单，占用空间小，可以方便安装，也可以降低照明装置10的生产成本。
在本发明的一些实施例中，如图6所示，壳体1可以包括：第一壳体50和第二壳体60，第一壳体50与第二壳体60相连，光源30和DMD芯片40可以设置在第一壳体50上，反射镜7可以设置在第二壳体60上，其中，第二壳体60位于第一壳体50的前侧，这样设置能够将反射镜7与光源30和DMD芯片40分开布置在不同位置，可以使反射镜7、光源30和DMD芯片40的布置位置更加合理。
在本发明的一些实施例中，如图6所示，DMD芯片40与镜头组件9之间形成有出射光路，在DMD芯片40处于打开状态时，光源30发出的光可以沿着出射光路从镜头组件9射出，实现照明装置10照明的工作目的。其中，照明装置10还可以包括：光吸收件91，光吸收件91可以设置在第二壳体60上，而且光吸收件91与反射镜7上下间隔开布置，反射镜7与光吸收件91之间具有出射光路。
在本发明的一些实施例中，光吸收件91的底部边缘和反射镜7的顶部边缘分别邻近出射光路设置，其中，光线从出射光路射出时，反射镜7和光吸收件91均不会影响光线从出射光路正常射出，如此设置能够减小照明装置10的体积，可以减小照明装置10的空间尺寸。
在本发明的一些实施例中，光吸收件91偏离于出射光路，而且光吸收件91用于在DMD芯片40处于关闭状态时，光吸收件91吸收由DMD芯片40反射的光线。其中，不需要照明装置10照明时，DMD芯片40处于关闭状态，光吸收件91将DMD芯片40反射的光线全部吸收掉，可以避免DMD芯片40反射的光线从照明装置10射出，从而可以保证不影响照明装置10的使用性能，并且，也能够使光吸收件91位于光吸收线路上，可以减小整个照明装置10的尺寸，从而可以节省车辆的安装空间。
在本发明的一些实施例中，光源30在第一壳体50上的安装面与水平面之间的夹角在40-50度之间，在上下方向以及前后方向上，这样设置能够降低光源30占据的尺寸空间，可以进一步减小照明装置10的体积。
在本发明的一些实施例中，光源30在第一壳体50上的安装面与水平面之间的夹角为45°，如此设置能够进一步降低光源30占据的尺寸空间，可以使光源30的布置形式更加合理。
在本发明的一些实施例中，如图7所示，照明装置10还可以包括：反 射镜姿态驱动装置8，反射镜姿态驱动装置8设置成用于驱动反射镜7动作，从而改变反射镜7相对DMD芯片40的朝向姿态。其中，反射镜7可以通过螺栓固定在第二壳体60上，在装配照明装置10的过程中，在安装反射镜7时，通过调整反射镜姿态驱动装置8，使反射镜姿态驱动装置8驱动反射镜7相对第二壳体60转动，从而实现调整反射镜7的位置的工作目的，这样设置方便调整反射镜7的位置，可以调整反射镜7相对DMD芯片40的角度，从而可以降低反射镜7的安装难度，进而可以提高照明装置10的装配效率。
进一步地，如图7所示，照明装置10还可以包括：调节轴70，调节轴70位于反射镜7的第一侧，反射镜姿态驱动装置8位于反射镜7的第二侧，反射镜7的第一侧和第二侧相对布置，反射镜姿态驱动装置8可以驱动反射镜7的第二侧绕调节轴70转动，如此设置能够实现驱动反射镜7绕调节轴70转动的工作目的，可以调整反射镜7相对DMD芯片40的角度。
在本发明的一些实施例中，送风装置的一部分对应光源散热区域11，送风装置的另一部分对应DMD散热区域12，需要说明的是，送风装置工作时，送风装置将一部分风吹向光源散热区域11，同时送风装置将另一部分风吹向DMD散热区域12，可以快速地对光源散热区域11和DMD散热区域12进行散热。
在本发明的一些实施例中，送风装置的一部分的送风面积大于送风装置的另一部分的送风面积，也可以理解为，送风装置与光源散热区域11对应的面积大于送风装置与DMD散热区域12对应的面积，其中，在单位时间内，光源30产生热量大于DMD芯片40产生的热量，这样设置能够使更多的风吹向光源散热区域11，可以保证对光源散热区域11的散热效果，也可以保证对DMD散热区域12的散热效果，从而可以使送风装置的布置形式更加合理。
在本发明的一些实施例中，送风装置面向分流结构2设置，DMD散热区域12位于分流结构2的上面，光源散热区域11位于分流结构2的下面，也就是说，DMD散热区域12位于分流结构2的上方，光源散热区域11位于分流结构2的下方，分流结构2位于送风装置的旋转轴线与送风装置的旋转轨迹的上沿之间，如此设置能够使送风装置与光源散热区域11对应的面 积大于送风装置与DMD散热区域12对应的面积，可以保证对照明装置10的散热效果。
在本发明的一些实施例中，分流结构2与送风装置间隔开布置，其中，在图4中的前后方向上，分流结构2与送风装置间隔开设置，这样设置能够避免分流结构2与送风装置接触，可以防止分流结构2与送风装置相互产生干扰，从而可以保证分流结构2和送风装置的工作可靠性。
在本发明的一些实施例中，光源散热区域11上可以设置有散热翅片，散热翅片与送风装置间隔开布置，但是散热翅片与送风装置的间隔距离小于分流结构2与送风装置的间隔距离。其中，散热翅片具有散热作用，如此设置能够使光源散热区域11上的热量传递至散热翅片，散热翅片将热量散出，从而可以快速地对光源散热区域11进行散热，进而可以提升对光源散热区域11的散热效率，并且，也能够使送风装置快速将风吹向散热翅片，可以快速将散热翅片上的热量带走，还能够避免散热翅片与送风装置接触，可以防止散热翅片与送风装置相互产生干扰，从而可以保证散热翅片和送风装置的工作可靠性。
在本发明的一些实施例中，热量传导断桥结构6形成在壳体1(即第一壳体50)的内壁面和/或外壁面上，也就是说，热量传导断桥结构6可以只设置在壳体1的内壁面上，也可以只设置在壳体1的外壁面上，还可以同时设置在壳体1的内壁面和外壁面上，例如：热量传导断桥结构6可以只设置在壳体1的内壁面上。
在本发明的一些实施例中，热量传导断桥结构6可以包括凹槽，照明装置10工作时，凹槽可以减少光源安装区域13的热量传导至DMD安装区域14的量，也可以减少DMD安装区域14的热量传导至光源安装区域13的量，从而可以实现热量传导断桥结构6的工作性能，进而可以使热量传导断桥结构6的设置结构更加合理。
在本发明的一些实施例中，凹槽可以设置为连续不间断的凹槽，或者凹槽为多段间隔开的凹槽，这样设置能够进一步降低光源安装区域13的热量传导至DMD安装区域14的量，也能够进一步降低DMD安装区域14的热量传导至光源安装区域13的量，可以进一步保证光源和DMD芯片的工作可靠性，从而可以进一步延长光源和DMD芯片的使用寿命。
在本发明的一些实施例中，凹槽可以构造为向上弯曲的弧形，所述DMD安装区域14位于凹槽的上方，光源安装区域13位于凹槽的下方，如此设置能够使凹槽更好地阻隔热量在DMD安装区域14与光源安装区域13之间传递，可以使DMD安装区域14、凹槽、光源安装区域13的布置位置更加合理。
在本发明的一些实施例中，凹槽分别向两侧延伸跨越DMD安装区域14，其中，在照明装置10的宽度方向上，凹槽分别向两侧延伸跨越DMD安装区域14，这样设置能够增大凹槽的布置面积，可以保证将DMD安装区域14和光源安装区域13间隔开，从而可以避免光源安装区域13的热量传递至DMD安装区域14。
在本发明的一些实施例中，分流结构2与热量传导断桥结构6位置对应设置，其中，热量传导断桥结构6设置在壳体1的内壁面上，分流结构2设置壳体1(即第一壳体50)的外壁面上，分流结构2与热量传导断桥结构6相对布置。
在本发明的一些实施例中，分流结构2一体地从壳体1的外表面向远离壳体1的内壁面的方向延伸，也可以理解为，分流结构2向外凸出壳体1，这样设置能够保证将光源散热区域11和DMD散热区域12分隔开，可以保证将一部分风引导向光源散热区域11，也可以保证将另一部风引导向DMD散热区域12，从而可以使分流结构2的布置更加合理。
在本发明的一些实施例中，如图2-图4所示，分流结构2可以具有第一分流面21和第二分流面22，第一分流面21朝向DMD散热区域12导风，第二分流面22朝向光源散热区域11导风。其中，风吹向分流结构2后，一部分风与第一分流面21接触后被第一分流面21引导至DMD散热区域12，另一部分风与第二分流面22接触后被第二分流面22引导至光源散热区域11，从而可以避免对DMD散热区域12散热的风与对光源散热区域11散热的风产生干扰，进而可以保证对DMD散热区域12和光源散热区域11的散热效果。
在本发明的一些实施例中，分流结构2可以构造为分流板23，但本发明不限于此，分流结构2也可以构造为与分流板23起到相同作用的结构。分流板23沿照明装置10的宽度方向延伸布置，这样设置能够增大分流结构 2在照明装置10的宽度方向上的长度，可以更好地把DMD散热区域12与光源散热区域11间隔开，从而可以进一步防止光源散热区域11处的热风被吹至DMD散热区域12，也可以进一步防止DMD散热区域12处的热风被吹至光源散热区域11。
在本发明的一些实施例中，如图4所示，光源散热区域11位于壳体1的下部，光源散热区域11构造为后端高而前端低的倾斜的斜面，光源散热区域11上可以设置有光源散热翅片3(即散热翅片)，光源散热翅片3具有散热作用，如此设置能够使光源散热区域11上的热量传递至光源散热翅片3，光源散热翅片3将热量散出，从而可以快速地对光源散热区域11进行散热，进而可以提升对光源散热区域11的散热效率。
在本发明的一些实施例中，如图3和图4所示，DMD散热区域12位于壳体1的上部，DMD散热区域12上可以设置有DMD散热翅片4，这样设置能够使DMD散热区域12上的热量传递至DMD散热翅片4，DMD散热翅片4将热量散出，从而可以快速地对DMD散热区域12进行散热，进而可以提升对DMD散热区域12的散热效率。
并且，如图5和图6所示，照明装置10还可以包括：安装支架5和送风设备51，送风设备51可以设置在第一壳体50之外,送风设备51可以将风吹向第一壳体50，安装支架5适于安装送风设备51(即送风装置)，送风设备51可以为风扇，安装支架5连接于第一壳体50，安装支架5固定安装在第一壳体50的外表面上，DMD散热翅片4的一部分位于安装支架5内，而且DMD散热翅片4的另一部分伸出安装支架5外。其中，送风设备51工作时，可以将风快速地吹向DMD散热翅片4、光源散热翅片3、DMD散热区域12、光源散热区域11和分流结构2，从而可以提升照明装置10的散热效率，进而可以避免照明装置10过温。同时，安装支架5能够阻挡风随意流动，可以使空气在金属散热翅片之间的流道内流动，从而实现空气与散热翅片之间的换热。
在本发明的一些实施例中，第一分流面21和第二分流面22为分流结构2的两个彼此背对的表面，例如：在照明装置10的上下方向上，第一分流面21位于分流结构2的上表面，第二分流面22位于分流结构2的下表面，如此设置能够保证第一分流面21可以将风导向DMD散热区域12，也能够 保证第二分流面22可以将风导向光源散热区域11，可以使第一分流面21和第二分流面22的设置位置更加合理。
在本发明的一些实施例中，如图2所示，多个DMD散热翅片4沿照明装置10的宽度方向间隔开布置，多个DMD散热翅片4配置成：位于最中间的一个DMD散热翅片4沿竖直方向上下延伸，也可以理解为，位于最中间的一个DMD散热翅片4在照明装置10的上下方向延伸布置，其它的任意一个DMD散热翅片4的下端与中间的DMD散热翅片4的距离小于其上端与中间的DMD散热翅片4的距离。其中，相邻的DMD散热翅片4之间形成流道，对DMD散热区域12散热的风沿流道流动，这样设置能够延长流道的长度，可以使流道内的风与DMD散热翅片4、DMD散热区域12进行充分换热，从而可以带走DMD散热区域12上的更多热量。
在本发明的一些实施例中，分流结构2可以设置成将风向上引导至DMD散热区域12以及向下引导至光源散热区域11，需要解释的是，分流结构2可以将风向上引导至DMD散热区域12，也可以将风向下引导至光源散热区域11，从而可以进一步保证将风引导至DMD散热区域12和光源散热区域11。
