值得一提的是，所述散热部本体111的结构形式是不限的，在此，作为一种可选的实施方式，所述散热部本体111呈圆柱形。
所述散热部本体111包括相对间隔设置的第一端面1111和第二端面1112和位于所述散热部本体111的外侧面且连接所述第一端面1111和第二端面1112的外侧面(图未标)；所述散热翅片112包括多个，多个所述散热翅片112沿自所述第一端面1111朝向所述第二端面1112的方向延伸且相互间隔设置。所述光源模块3设置于所述散热部本体111靠近所述第一端面1111一侧，所述光源模块3在运作的过程中能产生大量的热量，热量通过所述散热部本体111传导至所述散热器1以散发出去，通过多个所述散热翅片112的设置，有效地增加了散热器1与空气接触的面积，即提高了散热器1的散热面积，使得散热器1的散热性能优。
多个所述导流翅片12环设于所述散热部11周缘，多个所述导流翅片12沿自所述第一端面1111朝向所述第二端面1112的方向延伸且相互间隔设置，并与所述第二端面1112共同围成收容空间10，多个所述导流翅片12用以对所述风扇2产生的气流进行整流，以将述风扇2产生的气流引导至所述散热部11；进一步的，多个所述导流翅片12分别与多个所述散热翅片112连接，所述导流翅片12与所述散热翅片112一一对应设置。
更优的，为了提高散热翅片112和导流翅片12的连接的可靠性，散热翅片112和导流翅片12为一体成型结构。
所述光源模块3固定于所述散热器1靠近所述第一端面1111的一侧，而所述光源模块3与所述第一端面1111具体的位置连接关系是不限的，比如，本实施方式一中，光源模块3固定于导热管13并与第一端面1111相对间隔设置；当然，光源模块直接固定于第一端面上是可行的。所述光源模块3在运作的过程中能产生大量的热量通过所述散热部本体111传导至所述散热器1以散发出去。
所述风扇2固定于所述第二端面1112上，用以驱动气流吹向所述散热器1，以通过气流将所述散热器1的热量向外散发。

上述结构中，所述风扇叶22转动产生气流首先通过所述导流翅片12，由于所述导流翅片12的延伸方向与该气流的流动平行，所述导流翅片12对该气流进行整流，降低了该气流沿径向(即与气流的流动方向垂直的方向)向外的分速度，从而有效地减少了气流在流动过程中沿径向直接进入空气中的冷气量，提高所述照明装置100的散热性能；同时，所述导流翅片12的设置相当于增大了所述散热翅片112的面积，即增大了所述散热器1的散热面积，有效地优化了所述照明装置100的散热性能。
更优的，为了进一步提高所述散热器1的散热性能，本实施方式增设了导热管13，所述光源模块3通过导热管13将热量集中地传导至所述散热器1。
具体的，所述散热部本体111开设有贯穿其上的通孔(图未标)，所述导热管13插设于所述通孔内，导热管13由导热系数大于10000W/m*k的高导热材料制成；使所述光源模块3与所述导热管13连接，所述光源模块4产生的热量集中通过所述导热管13向所述散热器1传导，能够及时和有效地将热量快速向所述散热器1传导。
进一步的，所述散热部本体111还包括连接所述第一端面1111和所述第二端面1112且位于所述通孔内的内侧面1113。所述导热管13插设于所 述通孔内并与抵接于所述内侧面1113。
更进一步的，所述导热管13为实心的管状物，其可以为圆柱管或为多边形管；比如，在本实施方式一中，所述导热管13为实心的圆柱管，其包括导热段131和吸热端132。
所述导热段131插设于所述通孔内并抵接于所述内侧面1113，用以所述导热管13与所述散热器1之间的热量传导。
所述吸热段132连接于所述导热段131远离所述风扇2的一端且凸出于所述第一端面1111，用以所述光源模块3与所述导热管13之间的热量传导，所述电路板31贴设于所述吸热段132，所述吸热段132向外延伸有一定高度，使得所述电路板132与所述第一端面1111间隔设置，在安装过程中，所述吸热段132为所述光源模块3起到定位的作用，避免了所述光源模块3与所述导热管13的安装错位问题，确保安装的可靠性，而且保证所述导热管13优先与所述光源模块3直接接触；更具体的，所述吸热段132远离所述第一端面1111的端面1321连接所述光源模块3，所述端面1321作抛光处理，有效降低了所述端面1321的表面粗糙度，增加了所述端面1321与所述光源模块3之间的有效接触面积，从而提高了所述光源模块3与所述端面1321之间的热量传递的效率。
值得一提的是，所述吸热段132到所述第一端面1111的垂直距离即为所述吸热段132的延伸高度，该距离是不限的，其可以根据实际使用的需求进行具体的设置，而作为一个可选的实施方式，所述吸热段132到所述第一端面1111的垂直距离为0.05毫米至0.10毫米。
作为一个更优的实施方式，所述照明装置100还包括风扇外壳4；为了方便所述风扇外壳4的安装，所述导流翅片12靠近所述风扇叶22的一侧凹陷形成让位槽120，所述风扇外壳4固定套设于所述让位槽120且环绕所述风扇2设置。
通过所述风扇外壳4的设置，气流在经过所述导流翅片12时，保证了气流的流动方向与所述导流翅片12的延伸方向平行，从而达更好的整流效果，进一步增加了吹向所述散热器1的冷气量，使得所述照明装置100的 散热效果更优；同时，所述风扇外壳4充当所述风扇2的保护罩，避免了所述风扇外壳4受到外界的破坏，提高所述风扇2工作的稳定性，实现了所述照明装置100可靠地进行散热工作。
本实用新型还提供一种车灯200，其包括本实用新型所述的照明装置100以及光导模块5。

上述结构中，所述LED芯片32在工作中产生的热量传导至所述电路板31，并传导至所述散热器1进行散热，所述照明装置100能够及时将所述LED芯片32产生的热量及时散发，有效地提高所述车灯200的散热性能；同时，避免了所述LED芯片32内部的热量的积聚导致的老化问题，有效地提高了所述LED芯片32的工作的稳定性和可靠性，进而提高所述车灯200的可靠性。
值得一提的是，所述电路板31可以直接贴设于所述第一端面1111上，此时，所述光源模块3直接与所述散热部本体111接触，直接将热量传导至所述散热器1；当然，为了使得导热效率更高，作为一种更优的实施方式，所述散热器1可以增设导热管13，所述电路板31远离所述LED芯片32一端贴设于所述吸热段132的端面1321上，由于所述导热管13具有高导热性能，有效地将所述LED芯片32集中地更高效地将热量传导至所述散热器1中，提高了导热效率，进一步优化了所述车灯200的散热性能和可靠性。
所述LED芯片32与所述吸热段132对应设置，所述LED芯片32的横截面积小于所述吸热段132的横截面积，使得所述LED芯片32完全落在所述吸热段132的范围内，有效地确保所述吸热段132及时吸收所述LED芯片32产生的热量，从而使得所述照明装置100的散热效果更优，更进一步地提高所述车灯200的散热性能和可靠性。
更优的，所述电路板31与所述第一端面1111之间填设有高导热系数 材料，比如，本实施方式中，所述光源模块3与所述第一端面1111间隔形成间隙空间(图未标)，所述间隙空间内填充有用以所述光源模块3与所述第一端面1111之间导热的导热硅脂(图未标)，即将所述导热硅脂填充于所述电路板31与所述第一端面1111之间，所述电路板31一部分的热量通过导热硅脂直接传导至所述散热部本体111，从而更进一步增加所述电路板31与散热部本体111之间的导热面积，更有效地优化了所述车灯200的散热性能，使得所述车灯200的可靠性更高。

下面请同时参阅图5-10所示，将本实用新型的车灯200与相关技术的车灯200a进行对比，下面展开说明：
在开始说明之前，先对相关技术的车灯200a的结构进行简单的说明，所述车灯200a包括散热器1a以及分别装设于所述散热器1a相对两端的风扇2a和光源模块3a；所述散热器1a包括散热本体部11a以及固定于所述散热本体部11a且环绕所述散热本体部11a设置的散热翅片12a；所述光源模块3a包括贴设于所述散热本体部11a的电路板31a以及贴设于所述电路板31a远离所述散热本体部11a的一端的LED芯片32a。
图5为相关技术的车灯200a的气流流场示意图，未设置用于对气流进 行整流的结构，因此通过散热器1a的气流沿径向(即与气流的流动方向垂直的方向)向外的分速度大，从而导致大量冷气沿径向向外流出，其散热效果差；而图6为实用新型的车灯200的气流流场示意图，设置了导流翅片12对气流进行整流，降低气流沿径向(即与气流的流动方向垂直的方向)的分速度，减少不经过所述散热翅片112沿径向出流的冷气，同时增大了散热的面积，极大地提高所述照明装置100的散热能力，从而及时将所述LED芯片32产生的热量通过冷气流向外散发。
图7为相关技术的车灯200a的气流流场俯视图，气流的流线更加杂乱无章；而图8为实用新型的车灯200的气流流场俯视图，气流的流线有秩序地向外流出，减少沿径向远离所述散热翅片112的气流，保证吹向所述散热器1的冷气量。
图9为相关技术的车灯200a的温度分布示意图，如图所示，车灯200a中心的温度最高，即设置LED芯片32a的位置的温度达到最高，最高温度为131℃；而图10为实用新型的车灯200a的温度分布示意图，如图所示，LED芯片32贴设于导热管13，导热管13及时将LED芯片32的热量吸收并通过照明装置100向外散发，有效降低设置LED芯片32的位置的温度，此处的最高温度为117℃，本实用新型的最高温度较相关技术的最高温度降低了14℃。
实施方式二
请同时参阅图1-3及图11所示，实施方式二的车灯200’的结构及散热原理与实施方式一的车灯的结构及散热原理基本相同，在此不再赘述相同的部分，下面主要描述不同之处。
实施方式二的车灯200’与实施方式一的车灯的不同之处在于两者的导热管的结构形式不同。所述车灯200’的导热管13’包括导热段131’、吸热段132’以及放热段133’。
所述导热段131’插设于散热部本体111的通孔(图未标)内，所述吸热段132’连接于所述导热段131’远离风扇2的一端且凸出于第一端面1111。所述放热段133’连接于所述导热段131’靠近所述风扇2一端，且 所述放热段133’抵接于所述散热部本体111靠近所述风扇2的端面上，具体为所述放热段133’抵接于所述第二端面1112，且所述放热段133’呈扁平状，其有效地增强了所述导热管13’靠近所述风扇2一端径向的热量传导，增加了所述导热管13’与所述散热部本体111的接触面积，大大增加了散热的面积，提高了所述导热管13’与所述散热部本体111的热传导效率，更好地优化了散热器的散热效果，从而使得车灯200’的散热性能进一步优化和可靠性进一步提高。
需要说明的是，为了保证散热的效率，更优的，所述通孔包括至少两个且相互间隔设置，所述导热段131’包括至少两个且分别插设于所述通孔内，且所述导热段131’与所述通孔一一对应设置；所述放热段133’包括至少两个且分别与所述导热段131’靠近所述风扇2的一端连接，所述吸热段132’连接至少两个所述导热段131’远离所述风扇2的一端。当然，通孔、导热段131’以及放热段133’的数量是不限的，其可以根据实际上使用的情况进行具体的设置。
比如，在本实施方式二中，通孔包括两个且相互间隔设置，导热段131’包括两个，其中一个导热段131’插设于其中一个通孔内，另一个导热段131’插设于另一个通孔内；放热段133’包括两个，其中一个导热段131’连接于其中一个放热段133’连接，另一个放热段133’连接于另一个导热段131’。上述结构中，有效地保证了所述导热管13’与所述散热部本体111之间的散热面积，从而更进一步地提高所述车灯200’的散热性能和可靠性。
