具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施例对本发明进行详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。
请参阅图1，本发明导光装置10的较佳实施方式包括导光本体110、位于所述导光本体110第一端处的第一发光件130及位于所述导光本体110第二端处的第二发光件140，其中所述第一导光本体110的第一端与所述第二端相对设置。所述第一发光件130用于发出一条或多条第一光线，所述第二发光件140用于发出一条或多条第二光线，所述第一发光件130及第二发光件140发生的光线可在所述导光本体110内进行传输。
本实施方式中，所述导光本体110可包括位于第一端的第一光入射端面100、位于第二端的第二光入射端面102、光出射面104及与所述光出射面104相对设置的光反射面106。
所述光反射面106用于对所述第一光线及/或第二光线进行反射操作。本实施方式中，所述第一光线及/或第二光线中一部分光线可经由所述光反射面106的反射操作后由所述光出射面104出射；所述第一光线及/或者第二光线中的另一部分光线可沿所述导光本体110所在的传播路径进行传输。本实施方式中，所述导光本体110所在传播路径的开关可以为直线或非直线。例如，所述第一光线可由第一方向沿所述导光本体110所在的传播路径向第二方向传输；所述第二光线可由所述第二方向沿所述导光本体110所在的传播路径向所述第一方向传输。
本实施方式中，所述第一光入射端面100及所述第二光入射端面102可相对设置，如此，位于所述导光本体110第一端100处的第一发光件130所产生的第一光线与位于所述导光本体110第二端102处的第二发光件140所产生第二光线可在所述导光本体110在所述传播路径上进行混合、叠加，进而使得所述第一光线及第二光线可在所述导光本体110内及所述光出射面104出射可形成出光较均匀的光源。
可以理解地，所述第一发光件130可包括单色温的暖光或冷光发光元件的一种或者两种；所述第二发光件140可包括单色温的暖光或冷光发光元件的一种或者两种。
较佳地，当所述第一发光件130及第二发光件140均包括单色温的暖光发光元件时，所述导光装置10可形成双暖光的光源。当所述第一发光件130及第二发光件140包括单色温的冷光发光元件时，所述导光装置10可形成双冷光的光源。另外，在其他实施方式中，所述第一发光件130及第二发光件140亦均可包括2个暖光的发光件。所述第一发光件130及第二发光件140包含的发光元件的数量可根据实际需要进行相应的增减，以满足不同条件、场景下的光源的需求。
在其他实施方式中，所述第一发光件130可包括一个或者多个双色温的温光的发光元件，所述第二发光件140可包括一个或者多个双色温的温光的发光元件，以不同条件、场景下的光源进行搭配或者配制。
请一并参阅图2，所述第一发光件130及第二发光件140可均包含灯珠及反射杯。作为一举例说明，所述第一发光件130可包括灯珠131及反射杯133。所述灯珠131用于出射一条或多条的所述第一光线，所述反射杯133大致呈倒锥形，所述倒锥形的反射杯具有开口及底部。所述灯珠131设置于所述反射杯133的底部，所述反射杯133用于将所述灯珠131产生的一条或多条的所述第一光线进行反射，以使得所述灯珠131产生的第一光线尽可能多的由所述开口及所述第一入射端面100进入所述导光本体110内，以提高光源的利用率。较佳地，所述灯珠131产生的一条或多条件所述第一光线均可在所述反射杯133内产生全反射，进而使得所述灯珠131产生的第一光线均可入射至所述导光本体110。
在其他实施方式中，所述第一发光件130与所述第一入射端面100之间还可设置第一透镜(图未示)，所述第二发光件140与所述第二入射端面102之间亦可设置第二透镜(图未示)，所述第一透镜及第二透镜可用于对入射的光线进行扩散，以扩大入射光线的角度，进而使得进入所述导光本体110内的光线的分布较为均匀。较佳地，所述第一发光件130产生的第一光线可通过所述第一透镜的扩散后可产生具有较大的入射角度的光线，同理，所述第二发光件140产生的第二光线亦可通过所述第二透镜的扩散后产生具有较大的入射角度的光线。
所述第一发光件130及第二发光件140通过LED(Light Emitting Diode，发光二极管)封装(单色温/双色温芯片)，使得单位面积发光芯片输出光通量高，具有较大的驱动电流密度，可兼顾高显色，高亮度的效果。当然，所述第一发光件130及第二发光件140的显色及高度亦可通过控制电路板40(示于图7)进行调节。
请再参阅图1，较佳地，所述光反射面106上还设置有若干散射网点108。所述散射网点108的形状可为圆形、楔形中的一种或者多种。可以理解地，圆形散射网点具有各向同性散射；楔形散射网点可以适当补偿色散。因此，可根据实现需求，在所述光反射面106上设置不同数量的圆形散射网点或者楔形的散射网点。在其他实施方式中，所述散射网点108的形状亦不限于圆形、楔形，还可根据实际需要设置为其他形状，如椭圆等。
本实施方式中，由于采用对称双光源(包含第一发光件130及第二发光件140)，两个光源的衰减曲线应该满足对称衰减的特点，这样两个光源的叠加效果能够得到均匀的输出光。
可以理解地，单光源的衰减曲线：
P(x)＝P0e-cx
其中，C为散射网点的密度。考虑工艺和加工等方面的因素，可以采用均匀密度。
散射网点最大密度为：
Cmax＝lg(1-PC/P0)/xmax
其中，PC是材料传输光损耗和材料有关，xmax是导光板长度。
散射网点的尺寸原则上越小越好。但是考虑到工艺难度，一般在0.01～0.007mm左右即可。
在一实施方式中，所述散射网点108在所述光反射面106上分布的密度可随与光源距离的变化而变化。较佳地，所述散射网点108在所述光反射面106上分布的密度可随与光源距离成反向关系。例如，由于邻近发光件时，光通量较大，所述散射网点108分布的密度可较小；而远离发光件时，光通量较小，所述散射网点108分布的密度可适当增大，进而可使得所述导光装置10的出光较为均匀，可减少其因与发光件距离所带来的影响。
请一并参阅图3，所述导光本体110还包括内侧面112及外侧面114。所述导光本体110的内侧面112、外侧面114、光反射面106及光出射面104共同组成所述传播路径。所述导光本体110大致呈环形，所述第一发光件130及第二发光件140出射的光线可在所述环形的传播路径中传输。在另一实施方式中，所述内侧面112及外侧面114亦可涂上具有反光的材料，以使得所述第一光线及/或第二光线可较好的在所述传播路径上进行出射，以减少所述第一光线及/或第二光线从所述内侧面112及外侧而114出射，从而使得所述第一光线及/或第二光线尽可能多的由所述光出射端104出射。
在另一实施方式中，所述导光本体110的光反射面106上还可临近设置光反射装置70(示于图7)，所述光反射装置70可增加对所述第一光线及第二光线的反射强度，有利于减小光损耗，提高光的利用率。
本实施方式中，所述导光本体110的截面大致呈楔形，其中，所述内侧面112所在所述截面上的边的长度大于所述外侧面114所在所述截面上的边的长度，如此，可使得光向外扩撒开以至于不刺眼。
本实施方式中，所述灯珠131可靠近所述导光装置10的光反射面106设置，在其他实施方式中，所述灯珠131可靠近所述导光本体110截面中心轴线或者是楔形截面的窄边设置。例如，当所述内侧面112所在所述截面上的边的长度大于所述外侧面114所在所述截面上的边的长度时，由于所述传播路径在所述导光本体110内侧面与外侧面处传输的 路径不相同(外侧面的传播路径距离大于内侧面的传播路径)，如此，通过将所述灯珠131靠近楔形截面的窄边设置，可使得传播路径较长的一侧的光通量大于传播路径较短的一侧的光通量，有利于能够得到均匀的输出光。
请一并参阅图4，其为所述导光本体110的另一截面的较佳实施方式的示意图。所述导光本体110的截面大致呈楔形，其中，所述内侧面112所在所述截面上的边的长度小于所述外侧面114所在所述截面上的边的长度，如此，使得所述外侧面114的导光路径长，因此需要厚一些，可出射较多的光线，而所述内侧面112的导光路径短，因此需要薄一些使得出射光线在光出射面104的出射较为均匀。
另外，所述导光本体110上光出射面104可凸面圆弧形或者凹面圆弧形。可以使得出射光线按照特定光分布曲线在空间分布，如形成类蝙蝠翼型的IES曲线(如图5所示)，进而可使得在距离镜面10～50cm范围内(一般化妆范围)，使得光线较均匀分布于使用者面部，同时有利于降低眩光值。
请一并参阅图6、图7及图8，本发明化妆镜的较佳实施方式包括镜面30、收容所述镜面30及所述导光装置10的柔光装置20、用于控制所述导光装置10的色温及亮度的控制电路板40、用于支撑所述控制电路板40的支撑装置60、用于对所述控制电路板40散热的散热装置50及所述反光装置70。
所述柔光装置20包含第一收容空间202及第二收容空间204，所述第一收容空间202用于收容所述镜面30，所述第二收容空间204用于收容所述导光装置10。本实施方式中，所述柔光装置20可通过扣合部将所述镜面30扣合至所述第一收容空间202，以使得所述镜面30固定于所述第一收容空间202内。
本实施方式中，所述柔光装置20包括柔光部(图未示)，所述柔光部沿所述第一收容空间202的周长方向设置，并形成所述第二收容空间204。当所述导光装置10收容于所述第二收容空间204内时，所述导光装置10的光出射面104出射的光线可穿过所述柔光部，以对所述导光 装置10的出射光线进行柔光处理，进而使得所述导光装置10的出射光线均匀、柔和，也有利于降低眩光值。本实施方式中，所述柔光装置20可为具有雾化腐蚀透明的亚克力；在其他实施方式中，可在所述柔光装置20与所述导光装置10之间加入不影响显色的色粉，或者是在导光装置10与柔光装置20之间加入散光纸。

所述导光装置10大致呈环形，其具有开口200，所述开口200形成所述第一入射端面100及第二入射端面102。
所述支撑件60用于将所述控制电路板40及反光装置70与所述导光装置10及柔光装置20进行固定。本实施方式中，所述支撑件60的数量可为两个，所述支撑件60包括向上凸起的抵扣部600，邻近所述第一入射端面100的抵扣部600的外表面设有两个正对所述第一入射端面100的第一发光件130，邻近所述第二入射端面102的抵扣部600的外表面设有两个正对所述第二入射端面102的第二发光件140，如此，所述第一发光件130及第二发光件140发出的光线可分别从所述第一入射端面100及第二入射端面102入射至所述导光本体110。
本实施方式中，所述控制电路板40可包括控制电路，所述控制电路用于调节所述第一发光件130及第二发光件140的亮度及色温等信息。

所述电压输出引脚SW通过电感L1连接于所述电压输入引脚VIN，还连接于二极管D1的阳极。所述二极管D1的阴极通过串联的发光二极管D2、D3及电阻R6接地，所述二极管D1的阴极连接于所述侦测引脚OV，还通过电容C2接地。所述接地引脚GND接地。
