The invention provides a lighting device and a vehicle, and relates to the technical field of lighting. When the light-emitting elements in the first lighting branch to the Nth lighting branch can work normally, the input ends of the adjacent lighting branches are connected through the first communication circuit to the (N-1) th communication circuit, and the starting circuit works to control the current mirror circuit to work, so that the light-emitting elements in the first lighting branch to the Nth lighting branch are lightened; and when the light-emitting element of the ith lighting branch circuit has an open-circuit fault, the ith communication circuit is disconnected, so that the starting circuit cannot work, the current mirror circuit cannot be controlled to work, and the light-emitting elements of the first to Nth lighting branch circuits are all extinguished, so that when any lighting branch circuit has an open circuit, the current mirror circuit cannot be controlled to work. And the OFAF function that the light-emitting elements of all the lighting branches are extinguished expands the application range of the lighting device.
本发明提供了一种照明装置及交通工具,涉及照明技术领域。在第一照明支路至第N照明支路中发光元件均可以正常工作时,第一连通电路至第N‑1连通电路将相邻照明支路的输入端之间相连通,开启电路工作而控制电流镜像电路工作,以对第一照明支路至第N照明支路中的发光元件进行点亮;而在第i照明支路的发光元件出现开路故障时,第i连通电路将断开而使得开启电路无法工作,导致无法控制电流镜像电路工作而使得第一照明支路至第N照明支路的发光元件均熄灭,由此实现了任意一照明支路出现开路时,所有照明支路的发光元件均熄灭的OFAF功能,扩大了照明装置的适用范围。
