Description

一种照明装置及应用其的汽车 技术领域
本申请涉及照明设备技术领域，特别涉及一种照明装置及应用其的汽车。
背景技术
ADB(Adaptive Driving Beam，自适应远光灯)是一种智能远光灯系统。传统的汽车头灯，在夜间会车时容易使对向车道驾驶者的眩目，存在安全隐患。相比之下，ADB汽车大灯通过检测装置，如激光雷达或红外探测器等来检测前方道路的车辆或者行人，同时判断车辆或者行人与本人之间的位置和距离，并相应调整汽车前灯的照明光图案，关闭或调暗对面车辆或者行人所在区域的照明光，避免对来车的驾驶员或者行人造成眩目，其将成为汽车安全照明的发展趋势。
现有的ADB灯，通常包括依次设置的LED(Light Emitting Diode，发光二极管)阵列、匀光棒阵列以及透镜，LED发出的光经匀光棒匀光后，被透镜投射至前方，实现照明。由于匀光棒实际加工时会存在物理尺寸上的公差以及匀光棒安装时存在的误差，均会使得经透镜成像在前方道路上的光斑会存在暗条纹，导致整个ADB灯的照明不均匀。
发明内容
本申请提供一种照明装置及应用其的汽车，以解决现有技术中的ADB灯的照明不均匀的问题。
为解决上述技术问题，本申请采用的一个技术方案是：提供一种照明装置，其中，所述照明装置包括：
多个LED芯片；
多个匀光棒，所述匀光棒位于所述LED芯片的出光光路上，且每一 所述匀光棒与所述LED芯片一一对应设置，其中每一所述匀光棒远离所述LED芯片的端面为所述匀光棒的出光面；
第一透镜，设置在所述匀光棒的出光面一侧，所述第一透镜的前焦点位于所述匀光棒的出光面所在的平面之外。
通过以上设置，第一透镜可将匀光棒的出光面之外的某一平面成像至外部，可减少由于匀光棒加工精度不够对照明光均匀性造成的影响，降低对匀光棒出光面的加工精度，同时也可使得多个经第一透镜成像后的照明光斑之间不存在暗条纹，进而提高照明光图案的均匀性。

本申请通过将第一透镜的前焦点设置在匀光棒的出光面所在平面之外，即第一透镜将匀光棒的出光面之外的某一平面成像至外部，可减少匀光棒加工精度不够对照明光均匀性造成的影响，降低对匀光棒出光面的加工精度，同时也可使得多个经第一透镜成像后形成的照明光斑之间不存在暗条纹，从而可以提高经第一透镜成像的照明光的均匀性；同时将第一透镜的前焦点设置在出光面靠近LED芯片的一侧，可以使得经第一透镜成像的照明光斑的边缘色散后呈黄色，进而使得照明装置出射的照明光可以满足光色需求。

请参阅图1-图3，本申请中的照明装置100包括依次设置的多个LED芯片110、多个匀光棒120以及第一透镜130，其中，每一个LED芯片110与一个匀光棒120一一对应设置。
以其中一个LED芯片110和匀光棒120为例：
匀光棒120的一端正对LED芯片110，用于接收LED芯片110发出的光，另一端为匀光棒120的出光面121，匀光棒120用于接收LED芯片110发出的光并将其接收的光从出光面121均匀导出，其中匀光棒 120的作用是对LED芯片110出射的光进行匀化整形处理，使得匀光棒120中的光能够从出光面121均匀射出；第一透镜130设置在匀光棒120远离LED芯片110的一侧，且第一透镜130的前焦点F设置在出光面121所在的平面之外。
这里所说的前焦点F设置在出光面121之外是指，通过调整第一透镜130与匀光棒120之间的间距，从而使得第一透镜130的前焦点F可以位于出光面121远离LED芯片110的外侧，如图2所示；或者也可以使得第一透镜130的前焦点F位于出光面121靠近LED芯片110的一侧，即将第一透镜130的前焦点F设置在出光面121和LED芯片110之间的区域，如图3所示。
LED芯片110是将黄色荧光层设置在蓝光LED芯片上制备而成，蓝光LED芯片出射的蓝光激发黄色荧光层出射黄光，黄光与未被黄色荧光层吸收转化的蓝光混合后可形成白光，通过设置黄色荧光层的厚度使得LED芯片110出射光为白光。
本实施例中，通过将第一透镜130的焦点设置在出光面所在的平面之外，即第一透镜将匀光棒120的出光面121之外的某一平面成像至外部，而非将匀光棒120的出光面121成像至外部，此时，第一透镜130的焦平面上的像不受出光面121表面形状结构的影响，即使匀光棒120的出光面121存在加工精度不够的情况，对成像后的照明光斑的影响较小，通过以上设置，可降低对匀光棒出光面的加工精度，同时可使得各匀光棒120的出光面121经第一透镜130成像后形成的照明光斑之间不存在暗条纹，从而可以提高经第一透镜130的成像的照明光的均匀性。
在光学透镜中，不同波长的光会产生不同程度的色散，其中，短波长的光较长波长的光发生更大程度的折射。如图4(a)所示，当透镜前焦点处的黄光经透镜折射后准直时，蓝光将发生更大程度的折射而靠近光轴的方向偏折，使得经透镜成的远场的照明光斑的边缘呈蓝色；如图4(b)所示，当透镜后离焦处的蓝光经透镜折射后准直时，黄光将远离光轴的方向偏折，使得经透镜成的远场的照明光斑的边缘呈黄色；如图4(c)所示，当透镜前离焦处黄光经透镜折射后向靠近光轴的方向偏折， 蓝光也将更大程度地向靠近光轴的方向偏折，经透镜成的远场的照明光斑的边缘呈蓝色。
在本实施例中，当第一透镜130的前焦点F位于出光面121远离LED芯片110的外侧，即前焦点F位于出光面121和第一透镜130之间的区域时，此时穿过第一透镜130的成像光斑的边缘发生色散后呈蓝色；当第一透镜130的前焦点F设置在出光面121靠近LED芯片110的一侧，即前焦点F位于出光面121和LED芯片110之间的区域时，此时穿过第一透镜130的成像光斑的边缘发生色散后呈黄色。
现有的汽车照明装置的标准中，对照明光的色度要求中，一般为允许穿过第一透镜130的光的边缘发生色散呈黄色，因此，本申请中优选将第一透镜130的前焦点F位于出光面121靠近LED芯片110的一侧，即将第一透镜130的前焦点F设置在出光面121和LED芯片110之间的区域。此时，经第一透镜130成像至外部的照明光图案的边缘为黄色，使得照明装置100出射的照明光图案不仅具有较高的均匀性，同时满足光色的需求。
在本实施例中，第一透镜130的前焦点F距出光面121的距离L大于0mm且小于1.0mm，此时，经第一透镜130成像的照明光的均匀性较好，照明光斑的边缘呈黄色，且此时照明装置100的光效保持较高，照明光的亮度不受影响。当距离L继续增大时，照明装置100的光利用率将降低，照明光的亮度降低。
请进一步参阅图1，本申请中的照明装置100包括多个LED芯片110，其中，多个LED芯片110可以间隔排布，以减少LED芯片110产生的热量的聚集及各LED芯片之间的热量的相互影响；每一个LED芯片110均可以对应一个匀光棒120，且所有的匀光棒120的出光面121可以设置在同一个平面内，且各匀光棒120的出光面121之间紧密排列在该平面内，以减少各出光面121形成的照明光斑之间的间隙，提高照明光的均匀性。
其中，为了提高匀光棒120的匀光和整形效率且减小照明装置的体积，在本实施例中，匀光棒120为方形光导体，即匀光棒120垂直于其 光轴的截面可以为正方形或者长方形。在其他的实施例中，匀光棒120还可以是圆形光导体或其多边形光导体，即匀光棒120的截面设置为圆形、椭圆形或者其他的多边形等，在此不做限定。通过采用方形光导体，可以提高多个方形光导体之间的排列和安装，减少由于安装误差造成的光效的降低。
请参阅图6，图6是图5所示照明装置中的匀光棒另一实施例的结构示意图。
其中，匀光棒120包括相连接的方形光导体122和锥形光导体123，其中，锥形光导体123设置在方形光导体122远离LED芯片110的一端，方形光导体122和锥形光导体123可以是一体成型的，也可以是分开成型后再胶合成一体。在本实施例中，LED芯片110出射的光进入匀光棒120后，先经方形光导体122匀光后，再经锥形光导体123准直和整形后从出光面121出射。相对比于仅采用方形光导体的方案，本实施例中，设置在方形光导体端面的锥形光导体可进一步对方形光导体出射的光进行准直和整形，使得从出光面121出射的光的角度较小，照射距离更远。
本实施例中，方形光导体122垂直于其光导的截面可以设置为正方形或长方形，锥形光导体123靠近方形光导体122的端面与方向光导体的截面大小相同，出光面121可以设置成一组对边的边长与方形光导体122的一组对边的边长相同，另一组对边的边长大于方形光导体122的另一组对边。
其中，为了进一步节省设置空间，还可以将多个匀光棒120并排且一一紧靠设置，且多个匀光棒120的出光面121可以紧密排列。
本实施例中，一个LED芯片110与一个匀光棒120对应设置，可以控制一个匀光棒120的出光面121的发光情况，通过对每一个LED芯片110进行单独控制，从而可以实现对照明装置100的照明区域进行分区域控制，从而实现照明装置100区域可调的照明方式。
进一步，照明装置100还包括多个第二透镜140，第二透镜140设置在匀光棒120和LED芯片110之间的光路上，第二透镜140与LED 芯片110一一对应设置，第二透镜140的作用是对LED芯片110射的光进行收集和准直。其中，第二透镜140可以是球面透镜，通过对LED芯片110发出的大角度的光进行收集和会聚，从而使得原本无法射入到匀光棒120中的大角度的光通过第二透镜140折射后能够进入匀光棒120中，因此可以提高LED芯片110发出的光的利用效率。
本实施例中，每一个LED芯片110和其所对应的一个匀光棒120之间设置的第二透镜140可以是一个透镜，也可以是由多个透镜组成的透镜组，这里的多个是指两个或者两个以上。其中，LED芯片110可以设置在第二透镜140的焦点上。
其中，第二透镜140可以采用玻璃等耐热材料一体成型，能承受更高的热量，防止出现第二透镜140受热发生变形从而导致影响第二透镜140对LED芯片110发出的光线的收集和会聚效果。
请进一步参阅图1，本实施例中，照明装置100还包括LED芯片安装板150和散热组件160，LED芯片安装板150用于安装LED芯片110，其中，LED光源安装板150可以是设置有工作电路的电路板，如PCB(Printed Circuit Board，印制电路板)或者FPC(Flexible Printed Circuit，柔性电路板)，LED芯片安装板150与电源电连接以使得所有的LED芯片110可以与电源电连接而进行发光。其中，LED芯片安装板150上还可以设置控制器，控制器可以单独控制每一个LED芯片110的发光亮度或者是否发光。
本实施例中，LED芯片110通过LED芯片安装板150安装在散热组件160上，其中散热组件160包括基板161和设置基板161上的散热片162。其中，基板161上可以设置多个并排且间隔设置的散热片162，从而提高散热效果。在本实施例中，散热组件160包括主散热部160a和辅散热部160b，其中LED芯片110安装在主散热部160a处，辅散热部160b从主散热部160a沿LED芯片110的光轴方向延伸设置，用于对照明装置100中其他的光学组件进行散热，加强照明装置100的散热效果。
其中，本实施例中的照明装置100还包括外壳(图中未显示)，其 中外壳上设置有相应的固定结构以将第二透镜140、匀光棒120、第一透镜130以及散热组件160的位置固定，使得第二透镜140、匀光棒120、第一透镜130以及LED芯片110相对位置固定。
请参阅图图7。图7是图1所示照明装置中的发光单元的左视图。
本实施例中，一个LED芯片110及与其对应第二透镜140可以形成一个发光单元170。其中，照明装置100可以包括7个并排设置的发光单元170，在其他的实施例中，发光单元170的数量还可以是3个、5个、9个或者11个等，对于发光单元170的数量在此不做限定。
为了进一步提高照明装置100发光的均匀性，还可以在多个并排设置的发光单元170的边缘区域增设多个发光单元170。
请参阅图8，图8是图1所示照明装置中的发光单元另一实施例的左视图。
本实施例中，在中间区域设置有7个并排设置的发光单元170，且在这个7个发光单元170的周围可以均匀增设多个发光单元170，例如可以在7个并排设置的发光单元170的上下左右4个方向各增加一个发光单元170。在其他的实施例中，增设的发光单元170的数量还可以为多个，多个发光单元170在原有的并排设置的发光单元170的周围均匀分布。
进一步的，本申请还提供了一种汽车，请参阅图9，图9是本申请提供的一种汽车一实施例的结构示意图。其中汽车200可以包括如前文所述的照明装置100，其中照明装置100可以作为汽车200的大灯，其中汽车200内还可以设置检测装置210和控制装置220，控制装置220可以与照明装置100电连接并对每一个LED芯片110的发光情况进行单独控制，检测装置210用于检测照明装置100所对应的照明区域内是否有行人或者车辆，并识别具有行人或者车辆的照明区域所对应的LED芯片。
具体的，当汽车200在运行的过程中，检测装置210会对照明装置100的照明区域内的行人或者车辆进行检查，从而确定行人或者车辆在照明装置100的照明区域内的具体位置，进而可以确定行人或者车辆所 处的照明区域所对应的LED芯片110；当确定行人或者车辆所处的照明区域所对应的LED芯片110后，检测装置210会向控制装置220发出检测信号，控制装置220接收检测信号后根据检测信号控制与行人或者车辆所处的照明区域所对应的LED芯片110的发光情况，例如可以调节LED芯片110的亮度，使得此LED芯片110亮度下降或者直接关闭LED芯片110使得此LED芯片110停止发光。在此过程中，其余的LED芯片110还是处于正常的照明状态。
因此，本实施例中汽车200可以在不影响照明装置100的正常照明的同时，通过控制装置220对单一的一个或者两个以上的LED芯片110的发光情况进行控制，因此可以避免在照明装置100发出的光对行人或者车辆驾驶员造成眩目等不良影响，提高行车安全。
综上所述，本申请通过将第一透镜的前焦点设置在匀光棒的出光面所在的平面之外从而可以提高经第一透镜的成像的照明光的均匀性；同时将第一透镜的焦点设置在出光面靠近LED芯片的一侧，可以使得透过第一透镜发出的光的边缘色散呈黄色，进而使得LED芯片可以满足满足整个照明装置的光色要求；同时通过在匀光棒和LED芯片之间设置多个依次叠加设置的第二透镜，可以提高LED芯片的光利用效率；进一步的，通过控制装置对单一的一个或者两个以上的LED芯片的发光情况进行控制，因此可以避免在照明装置100发出的光对行人或者车辆驾驶员造成眩目等不良影响，提高行车安全。
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他相关的技术领域，均同理包括在本申请的专利保护范围内。
