图2为传统导光组件的结构示意图。
附图中各标号的含义为：
导光板10，发光部20，内表面21，外表面22，第一虚拟平面23，第三虚拟平面24，送光部30，出光面31，弧形面32，入光面33，第二虚拟平面34，光源40。
 本发明的实施方式
为了便于理解本发明，下面将对本发明进行更全面的描述。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
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。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。相反，当元件被称作“直接在”另一元件“上”时，不存在中间元件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只是为了说明的目的。
请参考图1，为本发明的导光组件，包括导光板10及光源40。导光板10包括发光部20及送光部30，发光部20呈环形状设置，发光部20具有内表面21及外表面22，送光部30设置在内表面21上。送光部30具有出光面31、弧形面32、以及连接出光面31和弧形面32的入光面33。出光面31贴合内表面21设置。弧形面32与出光面31之间的距离朝远离入光面33方向逐渐减小。入光面33位于送光部30的一端，入光面33相对倾斜设置。光源40靠近入光面33设置，光源40具有发光面，光源40的发光面与入光面33对应设置。
上述导光组件的光源40用于发出光线，送光部30用于将光源40发出的光线传递至发光部20中，发光部20用于将光线散射出来。可以理解地，光源40发出的光线经发光面及入光面33射入送光部30中，然后从出光面31传播至发光部20中，再通过发光部20散射出来。通过将入光面33倾斜设置，有利于延长光线从送光部30至发光部20入射的传播路径，尽可能多的入射到送光部30内，减少光线在未进入到送光部30之前就从侧面漏出送光部30外，使得光线在发光部20中的扩散性好，且因为延长了光线从送光部30至发光部20的入射传播路径，有效减弱发光部20中的局部亮斑，从而有效提高发光部20散射出来的光的均匀度，进而有效提高化妆镜的发光均匀度，使用效果好。
弧形面32的设置，使得进入送光部30中的光线能最大程度地导向至发光部20中，减少光线的损失，有效提高光的利用率，同时，由于弧形面32的设置，增加了光在发光部20中传导的长度，因送光部30的外侧设置为弧形面，从送光部30的内侧看所述弧形面32是呈现反弓形状的弧形面，光在经过反弓的弧形面的反射、折射，增大光的反射角度范围，从而使得光在进入到送光部30后经过反弓弧形面反射和折射，增加了光在导光板10中的反射次数和光折射次数，将光更大限度地导入至发光部20中，从而进一步有效提高发光部20散射出来的光的均匀度。需要加以说明的是，从送光部30射入的光在进入到发光部20后，经过导光板10中均匀分布的散射网点散射后将光散射布满整个导光板10，另外，设置的形状是弧形面，从而有效节约材料和降低成本。
发光部20可以为圆环、椭圆环、三角环或多边形环等。具体到本实施例中，发光部20为圆环，进一步地，发光部20为同心圆环，内表面21及外表面22均为圆弧面，且内表面21与外表面22同中心轴线p设置，由于出光面31贴合内表面21，从而出光面31也为圆弧面。在本实施例中，送光部30与发光部20一体成型制成。
在其中一个实施例中，送光部30的厚度小于发光部20的厚度，且送光部30的相对两侧均未延伸出发光部20。在另一个实施例中，送光部30的厚度大于发光部20的厚度，可以理解地，送光部30的一侧或相对两侧均延伸出发光部20。具体到本实施例中，送光部30的厚度等于发光部20的厚度，且送光部30的相对两侧面分别与发光部20的相对两侧面平齐，这里提到的相对两侧面指的是厚度方向的两个侧面，具体到本实施例中指的是发光部20和送光部30上下两侧的表面，可以理解地，送光部30的相对两侧表面分别与发光部20的相对两侧表面处于同一平面上。
在本实施例中，送光部30的数量为两个，且两个送光部30中心对称，有效进一步提高发光部20散射出来的光的均匀度。当然，在其他实施例中，送光部30的数量还可以为其他数量，可根据需求进行设计。
弧形面32远离入光面33的一端与出光面31远离入光面33的一端相连接，即弧形面32远离入光面33的一端与内表面21相接，可以理解地，弧形面32与出光面31之间的距离自弧形面32连接入光面33的一端朝弧形面32连接内表面21的一端逐渐减小直至消失，从而送光部30与发光部20之间通过弧形面32平滑过渡连接。具体到本实施例中，弧形面32的弧长为小于或等于内表面21的二分之一周长，且弧形面32的弧长大于内表面21的八分之一周长。
具体地，入光面33为平面，设入光面33与弧形面32之间的相交线为第一相交线e，设经第一相交线e及发光部20的中心轴线p所形成的虚拟平面为第一虚拟平面23，入光面33相对第一虚拟平面23倾斜设置，可以理解地，入光面33的延伸面未经过发光部20的中心轴线p，且送光部30整体设于第一虚拟平面23的一侧，即入光面33设于第一虚拟平面23与出光面31之间。进一步地，入光面33与第一虚拟平面23之间的夹角a大于0°且小于或等于30°。具体地，入光面33与第一虚拟平面23之间夹角a为15°。设出光面31与弧形面32 之间的相交线为第二相交线f，设经过第一相交线e及第二相交线f所形成的虚拟平面为第二虚拟平面34，第二虚拟平面34与入光面33之间的夹角b为5°至180°。具体地，第二虚拟平面34与入光面33之间的夹角b为120°。设第一虚拟平面23与外表面22的其中一个相交线为第三相交线k，设经过第三相交线k并相切外表面22的虚拟平面为第三虚拟平面24，光源40发出垂直于入光面33的其中一条光线为光路线n。
例如，如图2 ,为传统导光组件的结构示意图，入光面33’与第一虚拟平面23’重合，即入光面33’平行于第一虚拟平面23’重合，可以理解地，入光面33’的延伸面未经过发光部20的中心轴线p，同时，光源40’的发光面平行于入光面33’，第三虚拟平面24’与光路线n’之间在发光部20’中的最大宽度L’为10.8mm。本申请方案在图2的基础上，入光面33相对入第一虚拟平面23绕第一相交线e朝送光部30内（顺时针）旋转15°，光源40相对第一虚拟平面23朝送光部30方向（顺时针）旋转15°，第三虚拟平面24与光路线n之间在发光部20中的最大宽度L为25.1mm，如图1，很显然，第三虚拟平面24与光路线n之间在发光部20中的最大宽度L大于第三虚拟平面24’与光路线n’之间在发光部20中的最大宽度L’，由于角度旋转后，光在通过送光部30进入到发光部20中的传播途径变长，增大了光线之间的密度，光的扩散性变好，从而可以有效减弱发光部20中的局部亮斑。
在本实施例中，光源40的发光面为平面，且光源40的发光面与入光面33平行设置，从而光源40的发光面也倾斜设置。当然，在其他实施例中，光源40的发光面也可以为弧面。另外，光源40的发光面可与入光面33贴合，也可与入光面33相对间隔设置，可根据需求进行设计。
需要说明的是，在本实施例中，由于送光部30的数量为两个，从而光源40的数量也为两组，两组光源40分别与两个送光部30的入光面33对应设置。进一步地，每组光源40包括两个并列设置的LED灯。
本发明还提供一种化妆镜，包括镜面及上述所述的导光组件，导光组件的发光部20沿镜面的周长方向设置，导光组件的送光部20设置在镜面的背部，可以理解地，发光部20位于镜面的外围，处于人眼可见发光区域，送光部在镜面的背部，处于人眼不可见区域。进一步地，化妆镜还包括壳体及电源模块，镜面安装在壳体的正面，电源模块给光源40供电，光源40发出的光线经发光面及入光面33射入送光部30中，然后从出光面31传递至发光部20中，再通过发光部20散射出来。通过将发光部20呈环形状设置，可以补光更加均匀，沿镜面的周侧照过来，补光效果好。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
