Description

用于运行机动车用的照明装置的方法以及照明装置
技术领域
本发明涉及一种按照权利要求1的前序部分所述的用于运行机动车用的照明装置的方法以及一种按照权利要求7的前序部分所述的机动车用的照明装置。
背景技术
由CN101945513A已知前述类型的方法和装置。在该文献中说明的装置具有多个发光二极管(LED)。当这些发光二极管中的其中一个发光二极管失效时，这样驱控其它的发光二极管，使得它们更为明亮地发光。由此就从照明装置射出的光的总强度方面补偿了该发光二极管的失效。
通过叠加各个发光二极管的光产生了LED矩阵大灯的光分布。在此，矩阵大灯可以包括100个发光二极管。在诸如所谓的μAFS-LED大灯或带有基于LC显示器的像素光圈(Pixelblende)的大灯这样的高分辨率的大灯中，发光二极管或像素的数量明显可能更高。一些发光二极管或用作调制器件的LC显示器的一些区段的失效可能导致光分布中的空缺并且因此导致了光分布的干扰性的不均匀性。若在故障情况下未低于法定最低要求，那么通常不必更换大灯。尽管如此，在光分布中的空缺仍可能引起干扰性的视觉效果，所述干扰性的视觉效果降低了在机动车用户中的可接受度。
发明内容
本发明的任务是说明一种在开头提及类型的方法以及给出一种在开头提及类型的装置，所述方法和装置能避免或降低在由照明装置产生的光分布中的干扰性的视觉效果。
按照本发明，该任务通过带有权利要求1的特征部分的特征的在开头提及类型的方法以及通过带有权利要求7的特征部分的特征的在开头提及类型的装置解决。从属权利要求涉及本发明的优选的设计方案。
按照权利要求1规定，这样驱控光调制器件的所述至少一个未故障的区段或未失效光源中的所述至少一个光源，使得光分布的与所述至少一个失效的像素相邻的至少一个像素就其亮度被降低。以这种方式使单个光源或一些光源或一些像素的失效不那么明显，从而提高了用户的可接受度。
可以规定，这样驱控光调制器件的所述至少一个未故障的区段或未失效光源中的所述至少一个光源，使得光分布的与所述至少一个失效的像素相邻的多个像素就其亮度被降低。尤其可以规定，所述至少一个与光分布的所述至少一个失效的像素相邻的像素这样降低其亮度，使得从所述至少一个失效的像素到所述至少一个相邻的像素的过渡不具有生硬的梯度或者反差(Gradient)。由此可以避免从失效的像素到相邻的像素的生硬的过渡或光边缘，由此获得均匀的照明。
存在这样的可能性，即，这样驱控光调制器件的多个非故障的区段或多个所述未失效的光源，使得光分布的距离所述至少一个失效的像素不一样远的多个像素就其亮度被不同程度地降低，其中，与光分布的所述至少一个失效的像素相邻的至少一个第一像素比距离光分布的所述至少一个失效的像素更远的至少一个第二像素更为强烈地降低其亮度。以这种方式尽可能柔和地塑造从光分布的故障的部位到该部位周边的过渡，从而使一个像素或多个像素的失效几乎无法觉察。
例如可以规定，与光分布的所述至少一个失效的像素相邻的所述至少一个像素或处在该像素附近的像素就其亮度降低了10％至50％、特别是降低了20％至40％。通过相应地调整光源的调光值或像素的调光级可以这样来设计从所述至少一个失效的像素到该像素周边的过渡，从而使所述失效的像素不那么突出。
存在这样的可能性，即，计算新的光分布，该新的光分布考虑到了光调制器件的一个区段的故障或其中一个光源的失效并且在此具有从所述至少一个失效的像素到该像素周边的尽可能柔和的过渡，其中，根据重新计算的光分布来驱控光调制器件或光源。以这种方式能使光调制器件的多个区段或多个光源参与塑造从光分布中的空缺到该空缺周边的柔和的过渡。
按照权利要求7可以规定，控制器件可以执行按本发明的方法。
存在这样的可能性，即，照明装置除了光调制器件外还包括至少一个光源，所述光源的光在照明装置运行中射到光调制器件上并且由所述光调制器件在一些像素或成组的像素方面有针对性地反射或遮蔽或偏转，其中，由调制器件这样调制的光至少部分从照明器件射出。调制器件尤其可以构造成数字的微镜装置或者LCoS或LC显示器或者包括数字的微镜装置或者LCoS或LC显示器。
备选存在这样的可能性，即，光源构造成发光二极管或激光二极管，其中，发光二极管或激光二极管尤其布置成矩阵，例如其中，发光二极管集成为固态LED阵列。
照明装置可以是大灯、特别是高分辨率的大灯。
附图说明
接下来借助附图详细阐释本发明。附图中：
图1是带有深色区域的光分布的一部分的示意图，在该深色区域中，至少一个像素或多个像素基于光调制器件的一个区段的故障或基于其中一个光源的失效而失效；
图2是在按本发明对深色区域的周边沿水平方向调整下光分布的对应图1的图示；
图3是带有深色区域并且带有按本发明对深色区域的周边沿水平方向和垂直方向的调整的另一种光分布的一部分的示意图，在该深色区域中，至少一个像素或多个像素基于光调制器件的一个区段的故障或基于其中一个光源的失效而失效。
在附图中，相同的和功能相同的部分用相同的附图标记标注。
具体实施方式
在第一个实施例中，照明装置构造成高分辨率的大灯，其具有布置成一个矩阵的多个发光二极管。各发光二极管尤其能集成为固态LED阵列。大灯还包括控制器件，该控制器件计算光分布并且能通过相应地驱控各个发光二极管产生光分布。
在其中一个发光二极管失效时，在光分布1中产生了一个空缺，该空缺对应光分布1的一个像素2或多个像素2的失效。带有至少一个像素2失效的相应的空缺在图1中的光分布1中示出。在用按本发明的方法调整之前，到相邻像素3的过渡极为生硬。
控制器件可以作为对其中一个发光二极管的失效的反应而计算新的光分布1，新的光分布考虑到了其中一个发光二极管的这种失效并且在此尤其具有从在光分布1中的空缺到该空缺周边的尽可能柔和的过渡。根据这种重新计算的光分布1，由控制器件这样驱控各发光二极管，使得与在光分布1中的所述空缺相邻的像素3降低其亮度。
图2仅针对水平相邻的像素3示出了这一点。图3则针对水平和垂直相邻的像素3、4示出了这一点。像素3、4的降低的亮度用或多或少密集的点栅格表示。
在此，与光分布1的所述至少一个失效的像素2紧邻的像素3、4尤其比距离光分布1的所述至少一个失效的像素2更远的像素5、6就其亮度被更为强烈地降低。以这种方式获得了从光分布1中的空缺到该空缺周边的柔和过渡。在图3中示意性示出了亮度的相应的梯度7。
在第二个实施例中，照明装置构造成高分辨率的大灯，该大灯具有例如构造成发光二极管或激光二极管的光源和调制器件(Beeinflussungsmittel)。调制器件可以用于有针对性地在一些像素或成组的像素方面反射或遮蔽或偏转从光源射出的光。调制器件尤其可以构造成LC显示器。备选例如也考虑数字的微镜装置。大灯还包括控制器件，该控制器件计算光分布1并且能通过相应地驱控LC显示器的各个区段产生光分布。
在LC显示器的一个区段失效时，在光分布1中产生了一个空缺，该空缺对应光分布的一个像素2或多个像素2的失效。控制器件可以作为对LC显示器的一个区段的失效的反应而计算一个新的光分布1，该新的光分布考虑到了LC显示器的一个区段的这种失效并且在此尤其具有从在光分布1中的所述空缺到该空缺的周边的尽可能柔和的过渡。根据重新计算的光分布1，由控制器件这样来驱控LC显示器的各个区段，使得与在光分布1中的空缺相邻的像素3、4降低它们的亮度。
在这个实施例中，与光分布的所述至少一个失效的像素2紧邻的像素3、4比距离光分布1的所述至少一个失效的像素2较远的像素5、6就其亮度被更为强烈地降低。以这种方式获得了从光分布1中的空缺到该空缺周边的柔和的过渡。
