Description

前照灯用LED光源
技术领域
本发明涉及一种光源,尤其涉及一种机动车前照灯用LED光源。
背景技术
根据已经公开技术,世界上开发LED汽车前照灯的较先进而又有实用价值的结构归纳如下:
1 、多镜头组式。一个聚光镜与一颗LED成一镜头组,投射一光束,在屏幕上照明一个光斑。根据远光或近光标准要求,用多个镜头组产生的光斑拼接成光带,以符合照度分布要求。此结构体积大、成本高、工艺难。
2 、自由面透镜式。前照灯由一个聚光镜与一颗LED组成,但是聚光镜的折光面不再是旋转曲面,而是自由曲面,使光束投射产生光斑符合照度标准要求。此结构要求LED发光密度极高,发光密度即是发光面上的Lm/mm2值,用于近光灯尚可,难以用于远光灯。
3 、半反光镜-透镜式。此结构与透镜式HID灯相同,仅把LED当做沿轴线剖开的半个HID灯泡,只能适用于近光灯。
以上结构体现出,在设计思想中隐含LED是点光源这一观念,因此沿用HID灯结构,终究不能取得满意结果。
LED 光源是典型的面光源,至今,单个LED最高发光密度100 Lm/mm2,想要达到200 Lm/mm2以上几乎是不可能的。HID的发光密度在1000 Lm/mm2以上,卤素灯的发光密度也在400 Lm/mm2以上。
因此上述结构在使用LED作为光源的结构上,结构复杂,光能利用率低。
发明内容
为了解决上述技术问题本发明提供一种前照灯用LED光源,目的是节约能源,降低成本,提高光能利用率。
为达上述目的本发明前照灯用LED光源,其特征在于LED光源为连续发光的光带。
光带的每点发光密度公式为A×E1×F2=E2×L2,其中A为成像镜头集光系数,F为成像镜头 的焦距 ,L为投射距离,E1为光带发光点发光密度,E2为E1发光点对应检测屏幕上的成像点标准要求的照度;光带上发光点坐标公式为X,Y=实际成像点坐标/ 放大倍率,放大倍率=照明距离/ 成像镜头 的焦距。
光带为近光光源时,光带为曲面。
光带为一体。
光带为分体式,连接处无发光死区。
光带的发散角小于60度,大于0度。
光带为远光光源时,光带为平面。
光带为近光和远光结合光源时,远光光源设在近光光源的中心。
近光和远光结合光源时,当需要为远光光源工作时按远光光源控制发光点的发光照度,当为近光光源时,控制中心的远光光源按近光光源的发光照度工作。
本发明的优点效果:如图1所示本发明利用成像原理,将光源设计成为面光源的光带,结构简单,减少了前照灯的零部件,成本低,易实施,照明效果好。即使发光密度低,成本低廉也可轻易实现。
