技术领域
本发明属于车辆照明装置技术领域,具体一种远光照明装置。此外,还涉及一种包括所述远光照明装置的车灯和车辆。
背景技术
随着车辆的普及,行车安全日益受到人们的关注。当车辆在夜间行驶且道路照明光线比较暗时,通常会使用远光灯来观看前方路面的情况,但是,对向车辆的远光灯在会车时会对驾驶员眼睛产生较大的刺激,造成驾驶员瞬间炫目。在炫目时间里,驾驶员如同闭眼开车,对周围环境的观察能力大大降低,不利于驾驶员安全驾驶。另外,车辆在夜间行驶时,后方车辆远光灯的灯光会照射到车内外的后视镜上,强光反射到驾驶员的眼睛上,同样会使驾驶员产生瞬间炫目,影响驾驶员视线,尤其当车辆高速行驶时,会使刹车距离大大增加,严重影响了夜间驾驶的安全性。
因此,越来越多的车辆上采用了防炫目远光灯,该防炫目远光灯可以将对方或前方车辆所在的区域形成暗区,而其他照明区域无影响,避免干扰其他车辆正常行驶的同时还能照亮自身车辆前方的道路,可有效解决上述远光灯对驾驶员产生的影响,提高夜间行车的安全性。公告号为CN207762807U的中国发明专利公开了一种机械式无炫目远光模组,其采用机械式转动汽车左灯和右灯的遮光结构,在汽车前方车辆的位置处形成暗区,实现无炫目,但是,其要单独设置遮光滚轮以及驱动遮光滚轮转动的驱动结构,系统结构非常复杂;另外,以反射单元作为初级光学元件的车灯模组,多采用LED光源,其单位面积的光通量只有300-400lm/mm 2,导致发光面积大,进而反射单元的反射面较大,与反射单元匹配的透镜尺寸也较大,从而使得整个车灯模组的体积很大,并且因光源集中设置,不利于其有效散热。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是,此处所描述的具体实施方式仅用于说明和解释本发明,并不用于限制本发明。
在本发明的描述中,首先需要说明的是,除非另有明确的规定和限定,术语“连接”、“安装”应做广义理解,例如,连接可以是固定连接,也可以是可拆卸连接,或者是一体连接;可以是直接连接,也可以是通过中间媒介间接连接,可以是两个部件内部的连通或两个部件的相互作用关系。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本发明中的具体含义。
在本发明的描述中,需要解释的是,在下文的描述中为清楚地说明本发明的技术方案而涉及的一些方位词,例如“前”、“左”、“右”、“上”指的是车辆正常行驶状态下的前方、左右方向或者上方。此外,在GB4599-2007中规定,车辆前照灯的配光性能应在距离前照灯基准中心前25m的配光屏幕上进行测量;明暗截止线是指光束投射到配光屏幕上,目视感觉到的明暗显著变化的分界线,其中,L形明暗截止线指的是呈“L”形的明暗截止线,反L形明暗截止线指的是与“L”左右对称的形状的明暗截止线。
本发明第一方面提供的一种远光照明装置,应用于左车灯和右车灯,如图1至图3所示,其包括远光模组1和辅助照明模组2,其中,所述远光模组1包括聚光元件11和远光透镜12,所述聚光元件11的前端靠近所述辅助照明模组2的一侧形成有倾斜面114,所述倾斜面114设有或形成为反射面;所述辅助照明模组2包括辅助照明元件21,所述辅助照明元件21位于所述聚光元件11和所述远光透镜12之间,所述辅助照明元件21靠近所述聚光元件11的一侧侧面上设有或一体形成有遮光面211,远离所述聚光元件11的一侧侧面形成为辅助出光面212;所述遮光面211能够遮挡所述聚光元件11的部分出射光线,所述倾斜面114的前边缘线与所述遮光面211的后边缘线位于沿前后方向延伸的同一竖直平面上,以能够使从所述聚光元件11射出的光线经所述遮光面211遮挡后射至所述远光透镜12并经所述远光透镜12投射形成为具有L形或反L形明暗截止线的照明光形;所述辅助出光面212的出射光线能够射至所述远光透镜12并经所述 远光透镜12投射后能够形成补充光形,所述补充光形位于所述照明光形的所述明暗截止线一侧的无光区域处。
本发明的遮光面211的后边缘线与倾斜面114的前边缘线位于沿前后方向延伸的同一竖直平面上,其能够保证聚光元件11的出光边界,避免聚光元件11的光线从遮光面211的一侧射出,形成杂散光或者对应形成U形明暗截止线,也就是说,该聚光元件11的出射光线被遮光面211遮挡后经远光透镜12投射能够形成具有L形或反L形的明暗截止线的照明光形。优选地,从上向下的俯视图上可以看出,倾斜面114的前端边缘向下投影形成的点与遮光面211的后边缘线的上部端点O点214向下投影形成的点重合。
如图28所示,远光模组1中远光光源13射出的光线经聚光元件11汇聚并经聚光元件11的出光部113射出后,一部分光线直接射入远光透镜12,另一部分光线射至遮光面211,经遮光面211反射后再射入远光透镜12或射至远光透镜12以外且位于车灯内的部位,光线经远光透镜12投射后能够形成具有L形或反L形的明暗截止线的照明光形。
上述具有L形截止线的照明光形和反L形截止线的照明光形叠加后能够形成远光光形,该远光光形可以是常规的全远光光形,也可以是位于全远光光形中心区域的远光中心区域光形,如将本发明的远光模组1和辅助照明模组2应用于形成远光中心区域光形,相应地,车灯还需配置辅助远光模组3,形成能够与远光中心区域光形相匹配的远光展宽区域光形,两者叠加后形成全远光光形,下文所述的辅助远光模组3即为其中一种实施方式。当本车辆前方或对方有车辆或行人时,根据车辆或行人的位置以及所在区域的宽度,左右移动上述具有L形截止线的照明光形和反L形截止线的照明光形,两者叠加后形成具有暗区的远光光形。暗区覆盖前方或对方车辆或行人所在区域,能够有效避免远光对前方或对方车辆驾驶人员或行人产生干扰,防止产生炫目。当本车辆前方或对方没有车辆或行人时,增大上述两个照明光形的重叠部分,使两者叠加后没有暗区,能够给本车辆驾驶人员提供足够的远光照明。
以下以本发明的远光照明装置的远光模组1能够形成位于全远光光形中心区域的远光中心区域光形即主远光光形为例详细说明该发明的具体结构,该主远光光形能够确保远光光形的中心区域照度;辅助照明模组2的出射光线经远光透镜12投射能够形成补充光形,该补充光形位于上述照明光形的明暗截止线一侧的无光区域处,可以填补该无光区域,从而可以弥补远光模组1在车辆前方、或者对方无车辆或行人时形成的主远光光形的不足,能够有效改善远光照明效果。补充光形可以位于上述远光模组1形成的照明光形的明暗截止线一侧的无光区域内,优选为,补充光形的边缘能够与明暗截止线重合,以能够较为完整地补充上述远光模组1形成的照明光形。
由此可以看出,本发明的远光照明装置中的远光模组1能够形成具有L形或反L形明暗截止线的照明光形,辅助照明模组2则能够形成弥补L形明暗截止线或反L形明暗截止线一侧无光区域的补充光形。并且,本发明的远光照明装置中各零件结构简单且紧凑,体积小,照明效果好。
作为本发明的一个优选实施方式,所述聚光元件11包括多个聚光部111、通光部112和出光部113,所述倾斜面114形成于所述通光部112上。
更优选地,所述远光模组1还包括远光光源13和远光电路板14,各所述聚光部111形成为至少一排,所述远光光源13设于所述远光电路板14上,且各所述聚光部111与所述远光光源13一一对应设置。
上述聚光元件11的实施例中,聚光元件11包括多个聚光部111、通光部112和出光部113,可以使远光模组1结构更加紧凑,占用空间小,与各聚光部111的一一对应设置的远光光源13能够相对分散的设置,远光光源13的散热效果好。
作为本发明的另一个优选实施方式,各所述聚光部111采用硅胶成型,所述通光部112采用PC或PMMA成型。
如图4至图6所示,优选地,本发明的聚光元件11采用嵌件注塑一体成型,其生产过程为:先生产聚光部111,再将聚光部111作为嵌件与通光部112一体成型,或者直接采用双色注塑一体成型。聚光部111与通光部112之间形成为分界面115,分界面115的两侧为不同材料,两者折射率不同,使得分界面115同时具备了二次配光的功能,即增加了聚光元件11的配光面,光线能够从聚光部111偏转入射到通光部112,射至分界面115上的光线可以改变照射方向,从而可以实现调配光形角度以及改善光形均匀性的目的,提高配光自由度。并且,本发明的聚光元件11结构简单,满足嵌件一体成型或者双色注塑一体成型的工艺要求,适于大批量生产。
进一步优选地,本发明的分界面115可以为平面,也可以为曲面,或者是其他形状。
需要说明的是,硅胶的热变形温度高但是价格昂贵,体积占比较小且距离远光光源13较近的聚光部111采用硅胶成型,使得聚光部111不易受热变形,从而保障了出射光形的稳定性,而体积占比较大且距离光源较远的通光部112采用PC或PMMA成型,从而兼顾聚光元件11的成本控制和耐热性能要求。
作为本发明的又一个优选实施方式,所述补充光形的边缘能够与所述明暗截止线重合。
优选地,所述远光照明装置用于所述左车灯的情形下,所述遮光面211位于所述聚光元件11前方的左侧部分,其对应形成的所述明暗截止线形状为L形;所述远光照明装置用于所述右车灯的情形下,所述遮光面211位于所述聚光元件11前方的右侧部分, 其对应形成的所述明暗截止线形状为反L形。
作为本发明的一个具体结构形式,所述辅助照明模组2还包括辅助照明光源22和辅助照明电路板23,所述辅助照明元件21的入光端设有至少一个辅助聚光结构213,所述辅助照明光源22位于所述辅助照明电路板23上并与所述辅助聚光结构213一一对应设置。
如图29所示,辅助照明模组2中的辅助照明光源22射出的光线,经辅助聚光结构213汇聚进入辅助照明元件21,其中一部分光线直接由辅助出光面212射出,另外一部分光线射至遮光面211上,经遮光面211反射至辅助出光面212,所有经辅助出光面212出射的光线均射至远光透镜12后投射至无光区域。
作为本发明的另一个具体结构形式,如图9至图11所示,所述远光照明装置还包括辅助远光模组3,所述辅助远光模组3包括辅助聚光元件31、辅助远光光源32、辅助远光电路板33和辅助远光透镜34,所述辅助聚光元件31的入光面上设有多个聚光结构311,所述辅助远光光源32位于所述辅助远光电路板33上并与所述聚光结构311一一对应设置;各个所述辅助远光光源32可独立地点亮或者熄灭,所述辅助聚光元件31的出光面朝向所述辅助远光透镜34。
基于上述远光模组1和辅助照明模组2的实施例,如图1至图3所示,优选地,辅助照明元件21设于聚光元件11和远光透镜12之间,遮光面211一体成型于辅助照明元件21的尖角的一侧侧面上,将遮光面211与辅助照明元件21结合为一体,集成遮光和补充光形两个功能,优化了本发明的远光照明装置的结构。更具体地,辅助照明元件21靠近倾斜面114的一面上一体形成有遮光面211,辅助照明元件21上朝向远光透镜12的面形成为辅助出光面212,该遮光面211能够遮挡聚光元件11内射出的部分光线,能够使得这些光线不能投射至车辆前方而在车辆前方形成无光区域,使得远光模组1结合辅助照明模组2形成具有明暗截止线的照明光形。遮光面211与辅助出光面212呈尖角状,也可以理解为两者呈V形,此时,辅助照明光源22点亮时,辅助出光面212对应形成的补充光形的边缘与辅助照明光源22熄灭时遮光面211对应形成的明暗截止线能够更好地重合,对主远光光形的补充作用更佳,同时避免在远光模组1内单独设置遮光结构,使得远光模组1的结构简单,空间利用率高。
如图11所示,辅助聚光元件31的入光面上可以设有五个聚光结构311,五个聚光结构311分别对应一个辅助远光光源32,多个聚光结构311和对应的辅助远光光源32使得辅助远光模组3应用于左车灯或者右车灯时,能够分别形成多个在左右方向依次衔接的辅助照明区,相应地形成左车灯辅助远光光形或者右车灯辅助远光光形,各个辅助远光光源32可独立地点亮或者熄灭使得每个辅助照明区可单独地被控制点亮和熄灭, 以调整左车灯远光光形和右车灯远光光形的光形展宽角度。如图15所示,从上到下是左车灯辅助远光光形的辅助照明区从右往左依次熄灭所形成的不同展宽的左车灯辅助远光光形;如图16所示,从上到下是右车灯辅助远光光形的辅助照明区从左往右依次熄灭所形成的不同展宽的右车灯辅助远光光形;如图17所示,当左车灯辅助远光光形和右车灯辅助远光光形的辅助照明区全部点亮时,可形成完整的远光展宽区域光形;如图18所示,当本车辆前方或对方有车辆或行人时,根据车辆或行人的位置,将其所在区域对应的辅助远光光源32关闭,防止对车辆或行人产生炫目。
另外,本发明第二方面还提供一种车灯,包括根据第一方面技术方案中任意一项所述的远光照明装置和用于驱动所述远光照明装置左右移动的驱动机构。
本发明的远光照明装置可以设置于左车灯和右车灯中,如图12所示,当用于左车灯时,遮光面211遮挡的光线(未经远光透镜12投射的光线)和未遮挡的光线(经远光透镜12投射的光线)以其右侧边缘和上侧边缘为界,使得左车灯形成具有L形明暗截止线的左车灯主远光光形;如图13所示当用于右车灯时,遮光面211遮挡的光线和未遮挡的光线以其左侧边缘和上侧边缘为界,使得右车灯形成具有反L形明暗截止线的右车灯主远光光形,左主远光光形与右主远光光形叠加后能够形成如图14所示的具有暗区的主远光光形,暗区位于左明暗截止线与右明暗截止线之间。
上述车灯的实施例中,具有以下几种灯光照明效果:第一,如果本发明的远光照明装置设置于左车灯中,打开左车灯中的远光光源13和辅助远光光源32,根据需要将左车灯中辅助远光模组3的部分辅助照明区对应的光源熄灭,可形成如图19的具有不同光形展宽角度且具有L形明暗截止线的左车灯远光光形;若本发明的远光照明装置设置于右车灯中,打开右车灯中的远光光源13和辅助远光光源32,根据需要将右车灯中辅助远光模组3的部分辅助照明区对应的光源熄灭,可形成如图20所示的具有不同光形展宽角度且具有反L形明暗截止线的右车灯远光光形。第二,如果左车灯内的远光光源13和辅助远光光源32同时打开,则能够对应形成如图21所示的左车灯全远光光形;若同时打开右车灯中主远光光源13和所有辅助远光光源32,可形成如图22所示的右车灯全远光光形;。第三,如果左车灯和右车灯内的远光光源13和辅助远光光源32同时打开,则能够形成如图23所示的全远光光形。在夜间驾驶过程中,可根据不同驾驶情况,通过驱动机构调节左车灯和右车灯中远光照明装置的位置,达到调整具有暗区的远光光形的暗区的宽度及位置的目的,使得对方车辆或前方同向车辆处于暗区中,同时分别控制左车灯和右车灯中辅助远光模组3中辅助照明区所对应的辅助远光光源32的点亮或熄灭状态,以使得左车灯辅助远光光形和右车灯辅助远光光形具有相适应的光形展宽角度,与已形成的主远光光形相配合,形成如图24和图25所示的驾驶所需的远光光形。 进一步地,继续参见如图21至图23,由于遮光面211对应形成的无光区域导致主远光光形和辅助远光光形(所有辅助远光光源32点亮状态下)叠加时,无光区域所在的光形区域(照度等值线呈L形)的照度值较低,该区域的光形照度不均匀,使得光形效果不理想,此时,借助辅助照明模组2的辅助照明功能,补充这部分无光区域带来的光形缺陷,具体地,点亮辅助照明光源22,左车灯中辅助照明模组2形成如图26所示的左补充光形,右车灯中辅助照明模组2形成相应的右补充光形,与左车灯远光光形和右车灯远光光形相配合,能够形成如图27所示的光形照度均匀的全远光光形。综上,本发明的左车灯和右车灯形成的暗区的宽度和暗区所在的位置均可调整,调整时远光光形的展宽角度基本一样,不会造成照明范围过小而影响本车驾驶者的驾驶安全或者照明范围过大而使车辆摄像头的探测范围以外的车辆炫目,同时辅助照明模组2形成的补充光形,进一步完善全远光光形的照明效果,弥补由遮光面211造成的无光区域对全远光光形造成的不足,有效提高夜间驾驶的安全性。
需要说明的是,本发明中对驱动机构不作特殊的限定,优选地,驱动机构采用AFS旋转机构(Adaptive Front-Lighting System旋转机构,即自适应汽车前照灯系统旋转机构),AFS旋转机构的具体结构可参考专利CN207049828U。当然,本发明的驱动机构还可以选用其他结构形式的AFS旋转机构。
本发明第三方面还提供一种车辆,包括第二方面技术方案中所述的车灯。
以上结合附图详细描述了本发明的优选实施方式,但是,本发明并不限于上述实施方式中的具体细节,在本发明的技术构思范围内,可以对本发明的技术方案进行多种简单变型,这些简单变型均属于本发明的保护范围。
另外需要说明的是,在上述具体实施方式中所描述的各个具体技术特征,在不矛盾的情况下,可以通过任何合适的方式进行组合,为了避免不必要的重复,本发明对各种可能的组合方式不再另行说明。
此外,本发明的各种不同的实施方式之间也可以进行任意组合,只要其不违背本发明的思想,其同样应当视为本发明所公开的内容。
