Description

光源模组 技术领域
本申请涉及照明技术领域，特别是涉及一种光源模组。
背景技术
随着人们生活水平的提高，越来越多的人加入到了购车的行列，这也直接推动了汽车工业的发展，各大汽车公司都纷纷推出各种不同配置、不同价位的产品来满足不同的消费者。在汽车市场中，汽车的外形也变得越来越重要，作为汽车“眼睛”的汽车大灯模组自然也被更重视。
一般汽车的光源模组是利用椭球反光杯反射光源所发出的光线，并通过透镜将光线投射出去。然而，该技术方案难以兼顾照明光斑的中心亮度和照明光斑的宽度，导致照明光斑要么中心偏暗，要么光斑左右照射范围偏窄。为解决这一问题，一种技术方案是通过设置多个不同的光源，分别负责照明光斑的中心亮度和光斑的宽度，但该技术方案导致车灯结构臃肿，不利于紧凑型设计。
发明内容
本申请主要解决的技术问题是提供一种光源模组，能够通过紧凑型的光学设计，实现对出射光斑不同区域的光分布控制，改善光源模组的出光效果。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种光源模组，该光源模组包括光源、聚光元件以及凸透镜，光源用于发射光线；聚光元件设于光源的出光侧，聚光元件包括第一入射面和反射面，聚光元件用于将经过第一入射面的第一部分光线汇聚于第一汇聚点，并用于将经过反射面的第二部分光线汇聚于第二汇聚点；凸透镜设于聚光元件的出光侧，且凸透镜前焦点位于第一汇聚点上，第二汇聚点位于第 一汇聚点和凸透镜之间，凸透镜用于将第一汇聚点和第二汇聚点的光线投射出去。
通过上述方式，由于聚光元件将经过第一入射面的第一部分光线汇聚于第一汇聚点，且凸透镜前焦点位于第一汇聚点上，因此第一部分光源能够通过凸透镜的作用平行射出，由于聚光元件将经过反射面的第二光线汇聚于第二汇聚点，且第二汇聚点位于第一汇聚点和凸透镜之间，因此第二部分光源能够通过凸透镜的作用发散射出，从而使光源模组形成的光斑中间亮且面积大，故大大改善了光源模组的出光效果；另外，由于未设置多个不同的光源，因此能够使光源模组的结构更紧凑。
在一个实施方式中，聚光元件为全内反射透镜，聚光元件还包括第二入射面，第二入射面与第一入射面连接且环绕于第一入射面，反射面与第二入射面连接且反射面环绕于第二入射面，第一部分光线经第一入射面入射后直接透射至第一汇聚点，第二部分光线经第二入射面入射后在反射面进行反射至第二汇聚点。
在一个实施方式中，反射面沿垂直于聚光元件的主光轴的截面的离心率大于第一入射面沿垂直于聚光元件的主光轴的截面的离心率。通过上述方式，可以在较大程度上扩展第二部分光线的出光范围，从而得到大的光斑面积。
在一个实施方式中，聚光元件的主光轴经过第一入射面的中心。
在一个实施方式中，第一部分光线的外轮廓呈圆锥状，该圆锥状的圆锥角的范围为60°～120°。
在一个实施方式中，光源模组还包括活动挡光片，活动挡光片设置在第一位置时，活动挡光片在第一汇聚点处且活动挡光片靠近凸透镜的主光轴的侧边到达凸透镜的主光轴，光线经凸透镜射出后形成近光光型；在活动挡光片设置在第二位置时，活动挡光片不遮挡光线，光线经凸透镜射出后形成远光光型。通过上述方式，可以使光源模组实现远近光功能的切换。
在一个实施方式中，光源模组还包括驱动机构，驱动机构用于驱动活动挡光片动作，以使活动挡光片在第一位置和第二位置之间切换。通 过上述方式，可以使光源模组自动地实现远近光功能的切换。
在一个实施方式中，聚光元件还包括相邻设置的光出射面和光吸收面，光出射面和光吸收面之间的夹角小于170°，光出射面垂直于凸透镜的主光轴，以及光出射面和光吸收面的交线为阶梯状，光吸收面涂覆有吸光材料以形成吸光材料层。通过上述方式，由于光出射面和光吸收面之间的夹角小于170°，不仅可以减小聚光元件的体积，还可以使用户在涂覆吸光材料时更加容易。
在一个实施方式中，光源设置在聚光元件的主光轴上，光源的光轴与聚光元件的光轴不平行，且第一部分光线落入光出射面的光强大于落入光吸收面的光强。通过上述方式，可以使涂覆有吸光材料的光吸收面吸收少部分光线，而大部分光线通过光出射面投射出去，提高了光线利用率。
在一个实施方式中，凸透镜为非球面透镜，光源模组还包括散热器和灯板，灯板用于固定光源，散热器用于散出光源在工作时发出的热量。

光源模组包括光源11、聚光元件12以及凸透镜13。
在本实施例中，光源模组10可以为汽车灯模组，该汽车灯模组可以为汽车前灯模组或者汽车后灯模组等。光源模组10可以用于发出近光光型或者远光光型。在发出近光光型时，光束向地面侧倾斜，以避免迎面来车的驾驶员眩目；在发出远光光型时，光束向前方远处发射，以使光源模组10发出的光的强度高。
光源11用于发射光线。在本实施例中，光源11的个数可以为1个。在其它实施例中，光源11的个数可以大于1个，以增加光源11发射的光线的强度。在光源11的个数为大于1个时，大于1个光源的光轴可 以相互平行，也可以经过合光器件后合为一束光出射。
在本实施例中，光源11可以为LED光源。在其它实施例中，光源11可以为卤素光源、氙气光源或者激光光源等，还可以为激光荧光光源。其中，当光源为激光荧光光源时，光源包括激发光源和荧光片，荧光片可以替换到本实施例的LED的位置，从而达到与LED光源类似的效果。
聚光元件12设于光源11的出光侧，聚光元件12可以包括第一入射面121和反射面123，聚光元件12用于将经过第一入射面121的第一部分光线汇聚于第一汇聚点14，并用于将经过反射面123的第二部分光线汇聚于第二汇聚点15。在本实施例中，光源11的光轴与光源发出的最中心的光线重合，从而能够使得光源发出的光更多地在第一汇聚点14汇聚，保证光束照射区域的中心亮度达到要求。在本实施例中，第二部分光线环绕于第一部分光线，且光源的光轴在第一部分光线上，在其它实施例中，光源的光轴可以在第二部分光线上，此处不作限制。
第一汇聚点14和第二汇聚点15可以均位于聚光元件12的主光轴上，在本实施例中，第一汇聚点14和第二汇聚点15不重合。
聚光元件12可以为全内反射透镜。聚光元件12还包括第二入射面122，第二入射面122与第一入射面121连接且环绕于第一入射面121，聚光元件12的反射面123与第二入射面122连接且反射面123环绕于第二入射面122，第一部分光线经第一入射面121入射后直接透射至第一汇聚点14，第二部分光线经第二入射面122入射后在反射面123进行反射至第二汇聚点15。
聚光元件12的主光轴经过第一入射面121的中心。
第一部分光线的外轮廓呈圆锥状，圆锥状的圆锥角α1的范围为60°～120°，例如，该圆锥角α1可以为60°、90°或者120°。在本申请实施例中，可以通过改变光源与聚光元件之间的距离，从而改变圆锥角α1的角度。在圆锥角α1的角度越大时，第一区域16的亮度越高，第二区域17的亮度越暗，其中，第一区域16可以为光源模组出射的对应第一汇聚点的光线所形成的光斑区域，第二区域17可以为环绕第一区域16的区域，第一区域16的亮度比第二区域17的亮度高。
反射面123沿垂直于聚光元件12的主光轴的截面的离心率大于第一入射面121沿垂直于聚光元件12的主光轴的截面的离心率。
在本实施例中，反射面123沿垂直于聚光元件12的主光轴的截面可以为圆形，第二入射面122沿垂直于聚光元件12的主光轴的截面为椭圆形。在其它实施例中，反射面123沿垂直于聚光元件12的主光轴的截面和第二入射面122沿垂直于聚光元件12的主光轴的截面可以均为椭圆形，以及，第一入射面121和第二入射面122还可以有其它的形状，例如三角形、四边形、五边形、六边形等等，本实施例对此不作限定。
通过将第一入射面121沿垂直于聚光元件12的主光轴的截面设置为圆形，可以使光斑的第一区域16的形状呈圆形，以及将反射面123沿垂直于聚光元件12的主光轴的截面设置为椭圆形，可以使光斑的第二区域17的形状呈椭圆形。
凸透镜13设于聚光元件12的出光侧，且凸透镜13的前焦点位于第一汇聚点14上，第二汇聚点15位于第一汇聚点14和凸透镜13之间，凸透镜13用于将第一汇聚点14和第二汇聚点15的光线投射出去。由于凸透镜13的焦点位于第一汇聚点14上，因此凸透镜13能够将第一汇聚点14处的光线平行射出，第二汇聚点15位于第一汇聚点14和凸透镜13之间，即第二汇聚点15位于凸透镜13焦距内，因此凸透镜13能够将第二汇聚点15处的光线发散射出。
凸透镜13可以为双凸透镜13、平凸透镜13、凹凸透镜13或者非球面透镜。在本实施例中，凸透镜13为非球面透镜，在其它实施例中，凸透镜13可以为其它类型的凸透镜13，例如，双凸透镜13、平凸透镜13、凹凸透镜13等。通过将凸透镜13设置为非球面透镜，可以使凸透镜13具有更佳的曲率半径，从而使光源模组10出射的光更加符合用户的需求。
本实施例中，凸透镜13的主光轴和聚光元件12的主光轴重合，光源11设置在凸透镜13的主光轴或者聚光元件12的主光轴上。
可选地，凸透镜13在垂直于凸透镜13光轴的截面上的投影可以为 圆形、椭圆形或者多边形，其中多边形可以为三角形、四边形、五边形或者六边形等等。在本申请中，凸透镜13在垂直于凸透镜13光轴的截面上的投影为圆形。在其它实施例中，凸透镜13在垂直于凸透镜13光轴的截面上的投影还可以为其它形状，例如四边形或者六边形，本实施例对此不作限定。
光源模组10还可以包括灯板18，灯板18用于固定光源11。可选地，灯板18内还可以设置有控制电路(图未示)，控制电路用于控制光源11的亮灭。通过设置灯板18，可以使光源11发出的光仅照向灯板18的一侧，不仅可以提高了光的利用率，还可以增大了该侧光的强度。
光源模组10还包括散热器19，散热器19用于散出光源11在工作时发出的热量，以避免光源11在工作时发出的热量过高从而损坏光源11。可选地，散热器19还用于固定灯板18，进而固定在灯板18上的光源11。
请参阅图4～图6，图4是本申请第二实施例光源模组的活动挡光板遮光时的结构示意图，图5是本申请第二实施例光源模组的活动挡光板不遮光时的结构示意图，图6是本申请第二实施例光源模组发出的近光光型的第二光斑示意图。
在本实施例中，光源模组20包括光源(图未示)、聚光元件21以及凸透镜22。
其中，本实施例中的光源、聚光元件21以及凸透镜22可以为第一实施例中的光源11、聚光元件12以及凸透镜13。
光源模组20还包括活动挡光片23，活动挡光片23设置在聚光元件21和凸透镜22之间，活动挡光片23用于遮挡聚光元件21出射的部分光线，并在活动挡光片23遮挡部分光线时，未遮挡的光线经凸透镜13射出后形成具有明暗截止线的光型。
在本实施例中，活动挡光片23可以垂直于聚光元件21的主光轴设置。在其它实施例中，活动挡光片23可以不垂直于聚光元件21的主光轴设置。
更为具体地，活动挡光片23可以设置在第一汇聚点处，在活动挡 光片23设置在第一位置时，活动挡光片23在第一汇聚点处且活动挡光片23靠近凸透镜22的主光轴的侧边到达凸透镜22的主光轴，光线经凸透镜22射出后形成近光光型；在活动挡光片23设置在第二位置时，活动挡光片23不遮挡光线，光线经凸透镜22射出后形成远光光型。在其它实施例中，活动挡光片23还可以设置在第一汇聚点和聚光元件21之间或者第一汇聚点和凸透镜22之间，此处不作限定。
在本实施例中，近光光型所形成的第二光斑具有明显的截止线，第二光斑可以包括第三区域24和第四区域25，第三区域24较第四区域25明亮，第四区域25部分环绕第三区域24。远光光型所形成的光斑可以为第一实施例中的第一光斑。
可选地，光源模组20还可以包括与活动挡光片23连接的驱动机构(图未示)，驱动机构用于驱动活动挡光片23动作，以使活动挡光片23可以在第一位置和第二位置之间切换，进而使光源模组20发出近光光型和远光光型。
可选地，驱动机构可以有多种实现方式，例如可以采用通电磁吸的方式，即光源模组20需要发出近光光型时，驱动机构不动作，活动挡光片23靠近凸透镜22的主光轴的侧边在凸透镜22的主光轴的位置上，以挡住部分光源所发出的光，从而得到近光光型；在光源模组20需要发出远光光型时，驱动机构动作，此时驱动机构线圈通入电流，活动挡光片23靠近凸透镜22的主光轴的侧边向远离凸透镜22的主光轴的位置移动，以使挡光板不遮挡光线，从而得到远光光型。
活动挡光片23靠近聚光元件21的主光轴的侧边可以设置为台阶形。
台阶形可以分为第一段231、第二段232以及第三段233，第一段231、第二段232以及第三段233依次连接。在沿垂直于聚光元件21的主光轴的截面上，第一段231与第三段233的投影平行，第一段231和第三段233的投影还均与上述椭圆形的长轴平行。第一段231和第二段232之间的夹角可以为15°或者45°。其中，第一段231或者第三段233可以经过聚光元件21的主光轴，进一步地，第一段231与第二段 232的交点或者第三段233与第二段232的交点在主光轴上。
在其它实施例中，台阶形还可以分为第一段(图未示)和第二段(图未示)、第一段和第二段连接，第一段和第二段之间的夹角为15°。
通过将活动挡光片23靠近聚光元件21的主光轴的侧边设置为台阶形，从而可以使光线通过光源模组20射出的光为具有明暗台阶形截止线的光型。
可选地，活动挡光片23的材质可以为金属或者高分子等材料。还可以在活动挡光片23上涂覆第一吸光材料，以在活动挡光片23上形成第一吸光材料层(图未示)。通常第一吸光材料层呈现为黑色，因为黑色物质可以吸收所有颜色的光，当然也可以根据其他具体设计需求，采用其他的深颜色。该吸光材料层的材料可以为：氧化铁、炭黑、松烟怠、石墨、苯胺黑、硫化苯胺黑等。
请参阅图7～图8，图7是本申请第三实施例光源模组的结构示意图，图8是本申请第三实施例光源模组的截面示意图。
在本实施例中，光源模组30包括光源31、聚光元件32以及凸透镜33。同样地，聚光元件32包括第一入射面321、第二入射面322以及第三入射面323，第一入射面321、第二入射面322以及第三入射面323的连接关系可以与第一实施例中的第一入射面121、第二入射面122以及第三入射面123的连接关系相同。
其中，光源31、聚光元件32以及凸透镜33可以为第一实施例中的光源11、聚光元件12以及凸透镜13。
聚光元件32还可以包括相邻设置的光出射面323和光吸收面324，光出射面323和光吸收面324之间的夹角小于180°，光出射面323垂直于主光轴。可选地，光出射面323和光吸收面324之间的夹角范围可以为120°～175°之间。例如，光出射面323和光吸收面324之间的夹角可以为120°、165°或者175°。
光出射面323和光吸收面324的交线为阶梯状，光吸收面324涂覆有吸光材料以在光吸收面324的表面形成第二吸光材料层(图未示)。可选地，第二吸光材料层的颜色和材料可以和第二实施例中的第一吸光 材料层的材料相同。
通过将光出射面323和光吸收面324之间的夹角设置为小于180°，不仅可以减小聚光元件32的体积，还可以使用户在涂覆第二吸光材料时更加容易。
在本实施例中，光出射面323和光吸收面324的交线可以分为第一段325、第二段326以及第三段327，第一段325、第二段326以及第三段327依次连接，第一段325与第三段327平行，第一段325和第三段327还均与上述椭圆形的长轴平行。第一段325和第二段326之间的夹角可以为15°或者45°。其中，第一段325或者第三段327可以经过聚光元件32的主光轴。进一步地，第一段325与第二段326的交点或者第三段327与第二段326的交点在聚光元件32的主光轴上。
在其它实施例中，光出射面323和光吸收面324的交线可以分为第一段325和第二段326，第一段325与第二段326连接，第一段325与第二段326之间的夹角可以为15°。
在本实施例中，光源31设置在聚光元件32的主光轴上，光源31的光轴与聚光元件32的主光轴不平行，且第一部分光线落入光出射面的光强大于落入光吸收面的光强。可选地，光源31的光轴与聚光元件32的主光轴之间的夹角范围可以为5～60°。例如，光源31的光轴与聚光元件32的主光轴之间的夹角可以为5°、30°、45°或者60°。
例如，将本实施例中的光源模组30安装在汽车前灯时，可以将光源31向远离地面或者操作平台的一侧旋转，使光源31的光轴与聚光元件32的主光轴之间的夹角范围可以为5～60°，从而使光源31发出的大部分光线能够通过光出射面323射出，小部分光线被光吸收面324吸收，从而提高了光线的利用率。
区别于现有技术的情况，本申请的光源模组包括光源、聚光元件以及凸透镜，光源用于发射光线；聚光元件设于光源的出光侧，聚光元件包括第一入射面和反射面，聚光元件用于将经过第一入射面的第一部分光线汇聚于第一汇聚点，并用于将经过反射面的第二部分光线汇聚于第二汇聚点；凸透镜设于聚光元件的出光侧，且凸透镜前焦点位于第一汇 聚点上，第二汇聚点位于第一汇聚点和凸透镜之间，凸透镜用于将第一汇聚点和第二汇聚点的光线投射出去。
由于聚光元件将经过第一入射面的第一部分光线汇聚于第一汇聚点，且凸透镜前焦点位于第一汇聚点上，因此第一部分光源能够通过凸透镜的作用平行射出，由于聚光元件将经过反射面的第二光线汇聚于第二汇聚点，且第二汇聚点位于第一汇聚点和凸透镜之间，因此第二部分光源能够通过凸透镜的作用发散射出，从而使光源模组形成的光斑中间亮且面积大，故大大改善了光源模组的出光效果；另外，由于未设置多个不同的光源，因此能够使光源模组的结构更紧凑。
以上所述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它相关的技术领域，均同理包括在本申请的专利保护范围内。
