    • A lighting device for a vehicle comprises: a plurality of light source sections connected in parallel with each other; and a transformer for supplying an electric power to the plurality of light source sections. The transformer includes a primary coil and a plurality of secondary coils provided corresponding to the plurality of light source sections, for respectively supplying electric power to the corresponding light source sections. One end of each light source section is grounded and a semiconductor light emitting element is provided between one end and the other end of the light source section. The lighting device further comprises: a voltage detecting section for detecting voltages at the other ends of the plurality of light sources; and an output control section for controlling an electric current outputted from the transformer according to the voltage detected by the voltage detecting section.
    • 一种用于车辆的照明装置,包括:彼此并联连接的多个光源部; 以及用于向所述多个光源部提供电力的变压器。 变压器包括初级线圈和对应于多个光源部分设置的用于分别向对应的光源部分供电的多个次级线圈。 各光源部的一端接地,在光源部的一端与另一端之间设置有半导体发光元件。 照明装置还包括:电压检测部,用于检测多个光源的另一端的电压; 以及输出控制部分,用于根据由电压检测部分检测到的电压来控制从变压器输出的电流。
