根据透镜的调节值驱动透镜相对于光源转动，使透镜与光源之间的相对角位移得到快速调节。在本实施例中，通过驱动模块驱动透镜相对于光源转动，以使透镜相对于光源转动。
在其中一个实施例中，在根据透镜的调节值驱动透镜相对于光源运动的步骤之后，调节方法还包括：
将目标位置信息和相应的驱动信息存入数据库，以便下次直接调用，提高了灯具的调角效率及使用方便性。在本实施例中，当目标位置信息不属于多个预设位置信息的其中一个时，调节方法在步骤S103至步骤S107之间不断循环，直至当前位置信息与目标位置信息相等，即透镜的当前位置信息等于目标位置信息，同时将目标位置信息和相应的驱动信息存入数据库，以便下次直接调用，提高了灯具的调角效率及使用方便性。
在其中一个实施例中，本申请还提供一种调节系统，调节系统采用上述任一实施例调节方法进行调节。在其中一个实施例中，如图2和图3所示，本申请还提供一种调节系统400，调节系统400包括获取模块404、检测模块410、比较模块420以及驱动模块430。获取模块用于获取所述透镜与所述光源之间的目标位置信息。检测模块用于检测所述透镜与所述光源的相对位置信息，以得到所述透镜的当前位置信息。比较模块用于将所述当前位置信息与所述透镜的目标位置信息进行比较，得到所述透镜的调节值。驱动模块用于根据所述透镜的调节值驱动所述透镜相对于所述光源运动。
如图2所示，在其中一个实施例中，调节系统还包括建立模块402和调用模块406。建立模块用于将多个预设位置信息与多个驱动信息一一对应设置。调用模块用于在所述目标位置信息属于多个所述预设位置信息的其中一个，调用与所述预设位置信息相应的所述驱动信息，根据所述驱动信息调节所述透镜与所述光源的相对位置。在本实施例中，调节系统包括控制单元，控制单元包括调用模块406、检测模块410和比较模块420。
在其中一个实施例中，若所述目标位置信息不属于多个所述预设位置信息的其中一个，则检测所述透镜与所述光源的相对位置信息，得到所述透镜的当前位置信息。将所述当前位置信息与所述目标位置信息进行比较，得到所述透镜的调节值。根据所述透镜的调节值驱动所述透 镜相对于所述光源运动。
在调节透镜与光源的相对位置之前，先判断目标位置信息是否属于多个预设位置信息的其中一个，若是，则直接调用与预设位置信息相应的驱动信息，这样驱动整版透镜相对于光源运动至目标位置，实现灯具的快速调节，减少灯具的调节时间，提高了灯具调节速率和方便性；否则，检测透镜与光源的相对位置信息，得到透镜的当前位置信息，然后将当前位置信息与目标位置信息进行比较，得到透镜的调节值，然后根据透镜的调节值驱动透镜相对于光源运动，使透镜相对于光源进行调节。如此不断循环，直至透镜的当前位置信息等于目标位置信息，即透镜相对于光源调节至目标位置，实现灯具的调节。
如图2所示，在其中一个实施例中，控制单元通过有线或无线连接于驱动模块430的控制端。在其中一个实施例中，控制单元控制驱动模块430的转速和行程，进而控制整版透镜100的转动角度。在其中一个实施例中，驱动模块430与透镜100机械连接，以驱动整版透镜100相对于光源200转动，即对透镜100与光源200的相对位置进行调节，进而实现灯具的出光角度的无极调节。
如图2所示，在其中一个实施例中，检测模块410用来实时检测透镜100相对于光源200的角度信息，并与驱动单元之间反馈调节。在本实施例中，调角系统配合透镜100的透镜单元110的形状结构，共同实现灯具的出光角度的无级精准化调节。在其中一个实施例中，检测模块410包括照度采集探头或光强采集探头中的至少一种，如此检测模块410在驱动模块430的作用下能够检测得到完整的灯具的角度信息。
如图4与图5所示的实施例中，透镜100(如图3中示出)包括透镜单元110，透镜单元110与光源200(如图6中示出)相对应。透镜单元110的一面开设有出光槽112，出光槽112的内壁为第一出光面。第一出光面的法向截面为第一弧形线112a，且出光槽112朝向光源200设置，且透镜单元110与光源200的相对位置可调。透镜单元110背离开设有出光槽112的表面的一面为第二出光面114，第二出光面114与第一出光面相对应，且第二出光面114的法向截面为第二弧形线114a。在透镜单元110的不同法向截面位置，第一弧形线与第二弧形线的相对位置不同，以形成不同的出光角度。垂直于透镜单元110的位置调节方向的法平面为法向截面。
如图2所示，在其中一个实施例中，调节系统400还包括存储模块440，存储模块440用于存储多个预设位置信息与多个驱动信息一一对应的数据库，以便使用过程中能够快速调用，同时保证下次启动精确调节。在本实施例中，存储模块440用于存储多个不同的预设位置信息及其相应的驱动信息。预设位置信息为角位移信息。预设位置信息相应的驱动信息为驱动模块430驱动透镜100相对于光源200转动的驱动位移信息。
如图2所示，在其中一个实施例中，调节系统400还包括供电模块450，供电模块450分别与建立模块、所述获取模块、所述调用模块、检测模块410、比较模块和驱动模块430电连接，使供电模块能够对调节系统的各个模块进行供电。在本实施例中，供电模块450还用于与光源200电连接，使供电模块450可以对光源200进行供电。
如图3所示，本申请还提供一种灯具，灯具10包括光源200和透镜100。透镜100盖设于光源200上，且光源200发出的光线能够通过透镜100折射出来。光源200与透镜100的相对位置可调。在本实施例中，灯具10为庭院灯。在一实施例中，透镜100包括多个透镜单元110，多个透镜单元110连接于一起，使多个透镜单元110的出光角度能够同步调节。在本实施例中，多个透镜单元110连接于一起形成闭合结构。在其中一个实施例中，多个透镜单元110依次连接形成环状结构，使透镜100可通过旋转的方式沿位置调节方向进行调节，提高了透镜100的位置调节的方便性。在其他实施例中，多个透镜单元110依次连接不仅限于形成环状结构，还可以形成矩形结构或其他多边形结构。在其他实施例中，多个透镜单元110依次连 接也可以不形成闭合结构。在其他一个实施例中，多个透镜单元110依次连接形成弧形结构。
在其中一个实施例中，每一透镜单元110与光源200对应设置，使光源200发出的光线能够通过透镜单元110折射出来。如图4与图5所示，在一实施例中，每一透镜单元110的一面开设有出光槽112，出光槽112的内壁为第一出光面。第一出光面的法向截面为第一弧形线112a，且出光槽112朝向光源200设置，且透镜单元110与光源200的相对位置可调，使光源200能够调节至与透镜单元110不同相对位置处。
如图4与图5所示，其中，法向截面为垂直于透镜单元110的位置调节方向的法平面，即法向截面为垂直于透镜单元110的位置调节方向的截面。在本实施例中，通过旋转的方式调节透镜单元110与光源200的相对位置。可以理解，在其他实施例中，也可以通过平移的方式调节透镜单元110与光源200的相对位置。对于第一出光面的不同位置的法向截面，第一弧形线112a的形状不相同。
如图4与图5所示，在一实施例中，每一透镜单元110背离开设有出光槽112的表面的一面为第二出光面114。第二出光面114与第一出光面相对应，使光源200发出的光线依次经过第一出光面和第二出光面114折射出来。在其中一个实施例中，第二出光面114的法向截面为第二弧形线114a。在透镜单元110的不同法向截面位置，第一弧形线112a与第二弧形线114a的相对位置不同，以形成不同的出光角度。对于第二出光面114的不同位置的法向截面，第二弧形线114a的形状不相同。
由于透光单元的一面开设有出光槽112，且出光槽112朝向光源200设置，出光槽112的内壁为第一出光面，透镜单元110背离开设有出光槽112的表面为第二出光面114，又由于第二出光面114与第一出光面相对应，使光源200发出的光线能够依次经过第一出光面和第二出光面114折射而射出，实现灯具10的出光。由于在透镜单元110的不同法向截面位置，第一弧形线112a与第二弧形线114a的相对位置不同，这样光源200经过不同法向截面位置对应的出光槽112的内壁位置折射出来以形成不同的出光角度，这样在透镜单元110沿位置调节方向调节至相对于光源200的不同位置时，光源200的出光角度不同，实现灯具10的不同出光角度调节，以满足不同的配光角度要求，避免了传统的灯具10通过更换不同的二次透镜100来实现不同的配光角度的要求，解决了模具成本较高和时效性较低的问题。
在其中一个实施例中，出光槽112的延伸方向与透镜单元110的位置调节方向重合，使透镜单元110能够沿位置调节方向调节至与光源200对应的不同位置处，从而使光源200通过透镜单元110的不同位置折射出不同的光线，实现透镜单元110出光的连续性。在其中一个实施例中，出光槽112的延伸方向为曲线方向。在本实施例中，出光槽112的延伸方向为弧形方向，即出光槽112沿透镜100的圆周方向延伸的圆弧形方向。可以理解，在其他实施例中，出光槽112的延伸方向不仅限于为圆弧形方向，还可以为非圆弧形方向。在其中一个实施例中，出光槽112的延伸方向可以为不规则的闭合曲线方向。
如图4所示，为提高灯具10的照射角度范围，在其中一个实施例中，第二出光面114为弧形曲面结构，使第二出光面114具有较好的出光效果，同时使光线通过透镜单元110的第二出光面114在同一法向截面位置的不同位置折射出不同角度的光线，提高了灯具10的照射角度范围。
如图5所示，在其中一个实施例中，透镜单元110的一端的法向截面的出光角度大于透镜单元110的另一端的法向截面的出光角度。同时参见图6至图8，透镜单元110的出光角度从最大出光角度的端部向最小出光角度的端部递减，这样在透镜单元110沿位置调节方向调节过程中相应的出光角度递减或递增。
在其中一个实施例中，透镜单元110的出光角度范围为120°～135°，使透镜单元110的出光角度范围较大。如图6所示，在一实施例中，透镜单元110的最大出光角度为135°。当 透镜单元110的最大出光角度位置沿位置调节方向调节至与光源200的出光方向对应时，透镜单元110的出光角度最大。在本实施例中，当其中一个透镜单元110的出光角度调节至最大时，其他透镜单元110的出光角度同时调节至最大，此时整个透镜100结构的出光角度最大，此时的透镜单元110光斑图如图9所示，相应的透镜单元110配光曲线图如图10所示。
在一实施例中，透镜单元110的最小出光角度为120°。如图8所示，当透镜单元110的最小出光角度位置沿位置调节方向调节至与光源200的出光方向对应时，透镜单元110的出光角度最小。在本实施例中，当其中一个透镜单元110的出光角度调节至最小时，其他透镜单元110的出光角度同时调节至最小，此时整个透镜100结构的出光角度最小，此时的透镜单元110光斑图如图11所示，相应的透镜单元110配光曲线图如图12所示。在一实施例中，透镜单元110的最小出光角度位置对应的法向截面为两个同圆心的半圆结构，即透镜单元110的最小出光角度位置对应的法向截面的第一弧形线和第二弧形线均为半圆弧形线。可以理解，在其他实施例中，透镜单元110的最小出光角度位置对应的法向截面不仅限于两个同圆心的半圆结构。
如图7所示，在一实施例中，在透镜单元110的最小出光角度与最大出光角度之间存在一个中间出光角度。当沿透镜单元110的位置调节方向在透镜单元110的最大出光角度位置与最小出光角度位置之间调节至中间出光角度时，透镜单元110的出光角度为127.5°，此时透镜单元110的出光角度为中间出光角度。在本实施例中，当其中一个透镜单元110的出光角度调节至127.5°时，其他透镜单元110的出光角度同时调节至127.5°时，此时整个透镜100结构的出光角度为127.5°，此时的透镜单元110光斑图如图13所示，相应的透镜单元110配光曲线图如图14所示。
可以理解，在其他实施例中，透镜单元110的出光角度范围不仅限于120°～135°。也就是说，透镜单元110的最大出光角度不局限于135°，同理，透镜单元110的最小出光角度也不局限于120°，透镜单元110的最大出光角度和最小出光角度均可以通过调整透镜单元110的相应位置的结构来进行改变。
如图3与图15所示，在其中一个实施例中，相邻两个透镜单元110关于法向截面对称设置，使相邻两个透镜单元110对称连接共同组成与一个光源200相对设置的透镜单元组110a，从而使透镜100可以沿透镜单元110的位置调节方向的正反两个方向进行调节均能够实现光源200出光角度的增大或减小。在本实施例中，相邻两个透镜单元110的法向截面的出光角度较大的端部连接于一起，或相邻两个透镜单元110的法向截面的出光角度较小的端部连接于一起，使相邻两个透镜单元110关于法向截面对称设置。由于每一透镜单元110的两端的法向截面的面积不相等，相邻两个透镜单元110关于法向截面对称设置，可以使相邻两个透镜单元110的法向截面的面积相等的端部连接于一起，使相邻两个透镜单元110的连接位置较为平滑，从而使整个透镜100的结构较为平滑连贯。在本实施例中，多个透镜单元110沿着封闭圆形状的轨迹首尾相接阵列，形成环状的整版透镜100结构。
如图3所示，在其中一个实施例中，透镜100还包括固定架120，至少一个透镜单元110与固定架120连接，使多个透镜单元110在沿位置调节方向进行调节时均随固定架120运动。在其中一个实施例中，固定架120包括固定轴122和多个连接板124，每一连接板124的一端与固定轴122连接，另一端与透镜单元110连接。在本实施例中，连接板124的数目为三个。在一实施例中，多个连接板124沿固定轴122的周向间隔分布，使固定架120更好地连接于透镜单元110。在其他实施例中，连接板124的数目不仅限于三个，还可以是四个或其他数目。
如图6-8所示，出光槽112朝向光源200设置，且透镜单元110与光源200的相对位置可调。在其中一个实施例中，光源200的数目为N个。透镜单元110的数目为2N个，如图15所示，相邻两个透镜单元110关于法向截面对称设置，即相邻两个透镜单元110组成透镜单元组110a，如此组成N个透镜单元组110a。N个透镜单元组110a与N个光源200一一对应， 即每一光源200与相应的透镜单元组110a对应设置，使每一光源200发出的光线可以通过透镜单元组110a折射至外界。
如图3所示，在其中一个实施例中，灯具10还包括线路板300，光源200设于线路板上并与线路板电连接，使光源200电连接于线路板上。在其中一个实施例中，N个光源200沿线路板300的周向间隔设置于线路板300上，使灯具10具有较好的照明效果。在本实施例中，线路板300为PCB，使线路板300的厚度较薄。在其中一个实施例中，N个光源200均设于线路板的同一面上，使N个光源200均朝同一方向射出光线。在其中一个实施例中，灯具10还包括散热器500，线路板300设于散热器500上，使散热器500对线路板300的热量进行散热，提高了灯具10的散热性能。在本实施例中，线路板贴附于散热器上，使线路板上的热量能够传递至散热器上进行散热。在本实施例中，每一光源200设于线路板的背离散热器的一面。在其中一个实施例中，灯具还包括导热胶层，线路板通过导热胶层粘贴于散热器上，使线路板上的热量快速传递至散热器上。
如图3所示，在其中一个实施例中，灯具10还包括转轴600，转轴600与固定架120连接。线路板300开设有第一通孔310，散热器500开设有与第一通孔310连通的第二通孔410。转轴600分别位于第一通孔310和第二通孔410内，且转轴600分别与线路板300和散热器500转动连接，使固定架120随转轴600相对于线路板300转动，由于固定架120与至少一个透镜单元110连接，且多个透镜单元110连接于一体，使N个透镜单元组110a(未示出)均随固定架120转动，从而使N个透镜单元组110a(未示出)均相对于相应的光源200运动，使每一透镜单元组110a(未示出)沿位置调节方向相对于光源200调节至不同的位置，实现灯具10的不同出光角度的调节。
可以理解，转轴600可以通过人工手动的方式沿位置调节方向调节灯具10的不同出光角度。在其他实施例中，转轴600也可以通过动力驱动的方式沿位置调节方向调节灯具10的不同出光角度。
在其中一个实施例中，灯具10还包括上述任一实施例的调节系统400。所述获取模块获取所述透镜与所述光源之间的目标位置信息。检测模块410检测透镜100与光源200的相对位置信息。比较模块将当前位置信息与透镜100的目标位置信息进行比较，并根据透镜100的调节值输出控制信号。驱动模块430根据控制信号驱动透镜100相对于光源200运动。
上述的灯具及调节系统400，灯具包括光源200、透镜100和调节系统400，由于光源200与透镜单元110的相对位置可调，调节系统400的驱动模块430驱动透镜100相对于光源200运动，由于调节系统400采用上述的调节方法进行调节，可以适应灯具的调节位置范围内的任意目标位置的调节，实现灯具配光的无级调节。
再次参见图3，在其中一个实施例中，驱动模块430的动力输出端与转轴600连接，使驱动模块430驱动转轴600分别相对于散热器500和线路板300转动，实现灯具10的不同出光角度的自动调节。在本实施例中，驱动模块430包括电机433和连接轴435，连接轴的一端与电机的动力输出端连接，连接轴的另一端与转轴600连接。当电机驱动连接轴转动时，连接轴带动转轴600和固定架120转动，使透光单元随固定架120相对于线路板300转动，从而使每一透光单元组相对于相应的光源200运动，实现灯具10的出光角度的调节。在其他实施例中，电机还可以采用旋转气缸进行替换。
如图2所示，在其中一个实施例中，灯具还包括远程控制中心460，获取模块还与远程控制中心460连接。在本实施例中，获取模块与驱动模块430的控制端连接。获取模块还与远程控制中心460连接，使获取模块与远程控制中心460通信连接。具体在本实施例中，获取模块通过有线或无线连接于远程控制中心460。可以理解，远程控制中心460可以是远程中央集控中心或现场遥控单元，以控制单个或区域内的多个灯具的出光角度的调节。
在其中一个实施例中，灯具的工作过程为：远程控制中心460发出可调角度范围内任意角度信号给获取模块，控制单元判断此角度是否在存储模块440中。如果存储模块440中有此角度数据，驱动模块430驱动转轴带动整版透镜100转动至目标角度位置，点亮所有的LED，可以得到所需的灯具的出光角度。如果存储模块440中没有此角度数据，检测模块410检测透镜100的当前角度位置，通过检测模块410与驱动模块430之间的多次反馈优化，得到整版透镜100的目标角度位置，点亮所有LED，可以得到所需的灯具的出光角度，同时存储此时的目标角度位置信息及相应的驱动信息，便于下次调节时条件调用。
当对于上述的灯具的出光角度没有具体要求时，可以通过远程控制中心460的触摸屏或者实体按键，发出无级调节信号，从大到小或者从小到大调节灯具的出光角度，直至灯具使用现场的效果满意为止。当有系列的N个灯具组成的灯具系统需要统一调节时，即对N级灯具系统需要统一调节时，由远程控制中心460向各个灯具统一发出控制信号即可实现N级调控。如图16为灯具系统的拓扑示意图。
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申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请的保护范围应以所附权利要求为准。
