The invention relates to a vehicle lamp power supply circuit and a vehicle, the vehicle lamp power supply circuit comprises a transformer, a first secondary side control circuit and a second secondary side circuit, the second secondary side circuit comprises a power supply branch and an alarm branch, and the transformer comprises a primary winding, a first secondary winding and a second secondary winding; the first secondary side control circuit is connected with the first secondary winding, the power supply branch circuit is connected with the second secondary winding and the alarm branch circuit, and the alarm branch circuit is used for rectifying the alternating current output by the second secondary winding to obtain the direct current of the target voltage. According to the corresponding relation between the target voltage and the vehicle input voltage, it is determined that the input voltage of the vehicle is too large, the too large input voltage of the vehicle is accurately prompted to a maintainer through the alarm information output by the alarm branch, the diagnosis time of vehicle faults can be effectively shortened, and the maintenance efficiency of the vehicle is improved.

    本公开涉及一种车灯供电电路及车辆,车灯供电电路包括:变压器、第一副边控制电路和第二副边电路,第二副边电路包括供电支路和报警支路,变压器包括初级绕组,第一次级绕组和第二次级绕组;第一副边控制电路,与第一次级绕组连接,供电支路,与第二次级绕组和报警支路连接,报警支路,用于对第二次级绕组输出的交流电进行整流,以得到目标电压的直流电,这样,能够通过在报警支路确定目标电压大于预设电压阈值的情况下,根据目标电压与车辆输入电压的对应关系,确定车辆的输入电压过大,并通过报警支路输出的报警信息,准确地向维修人员提示车辆的输入电压过大,能够有效减少车辆故障的诊断时间,提高车辆的维修效率。
