进一步地,所述整形挡板16设于所述近光导光部件14远离所述LED近光灯源12的一端并用于使所述LED近光灯源12发出的光线形成明暗截止线,当采用所述LED车灯1的车辆行驶于路面上时,通过所述整形挡板16可使所述LED近光灯源12发出的光线尽量避开对应对面来车的驾驶座的位置,避免影响对面来车的驾驶员的视野,从而提升安全性。
优选地,所述自由曲面透镜17靠近所述散热基座11的一端设为入光面(图未示,下同),所述自由曲面透镜17远离所述散热基座11的一端 设为出光面171。所述出光面171包括近光透射区1711和远光透射区1712,所述近光透射区1711位于所述近光导光部件14的出光位置处,所述远光透射区1712位于所述远光导光部件15的出光位置处,所述近光透射区1711和所述远光透射区1712的出光角度不同。本领域技术人员可通过调整所述出光面171的面型使所述近光透射区1711和远光透射区1712能够实现不同的配光及聚光效果,通过一个自由曲面透镜17便能够满足近灯光和远灯光的光型透射需求,使所述LED近光灯源12和LED远光灯源13均能够实现特定的照明光型,无需额外配置反光杯进行集光,结构简单轻巧且光能损失小。
更优地,所述入光面上设有均匀排布的麻点结构(图未示,下同),所述麻点结构为在所述入光面切割形成的细小纹路,具体可为螺纹纹路,通过所述麻点结构使所述LED车灯1的出光更加均匀及平滑,避免光线过于锐利,提升照明效果。
在其他实施方式中,也可将所述麻点结构替换为菲涅尔透镜,即所述LED车灯1还包括设于所述入光面上的菲涅尔透镜(图未示,下同),通过所述菲涅尔透镜同样能够均匀化光源以及平滑化边缘。
在其他实施方式中,所述LED远光灯源13还可设有多个,多个LED远光灯源13等距阵列于所述散热基座11的远光安装面112,通过所述多个LED远光灯源13可直接提升所述LED车灯1的远光灯亮度的同时,还能通过调整所述多个LED远光灯源13的位置和角度组合出不同的远光光型,提升所述LED车灯1的个性度和识别度,进而提升产品竞争力。
优选地,所述LED车灯1还包括与所述LED远光灯源13电连接并可控制至少一个所述LED远光灯源13的亮度的远光控制模块(图未示,下同),通过所述远光控制模块控制不同LED远光灯源13的亮暗变化,可以选择特定区域进行照明或者选择特定区域进行遮蔽,从而进一步提升远光光型的多样化,使所述LED车灯1的远光灯输出更加智能化,能够 适应不同场景和不同的使用需求,具有较好的灵活性。例如,当所述LED车灯1被配置于右舵车上时,在对向来车时可通过所述远光控制模块降低左侧LED远光灯源13的亮度,保证右侧LED远光灯源13照明效果的同时,避免对其他车辆的正常行驶造成影响。
作为第二方面,本实用新型还涉及一种车辆(图未示,下同),包括车身和设于所述车身上的上述LED车灯1,由于所述LED车灯1结构简单紧凑、占用空间小、光能效率高且具备多样化的光型,使所述车辆的设计自由度高,可降低成本并实现轻量化,具有较好的灯光照明效果,提升夜间行驶的舒适性和安全性。
以上所述仅是本实用新型的部分实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。
