摘要： In one embodiment, a lighting device includes an LED lighting circuit and an LED load constituted by a plurality of parallel circuits formed by connecting a plurality of LED elements in parallel, and a series circuit formed by connecting the parallel circuits. The series circuit is connected with an output terminal of the lighting device. In case one LED element becomes open fault mode in one of the parallel circuit, the other LED elements continue lighting. In case two or more LED elements become the open fault mode, the other LED elements also become the open fault mode, and all the LED elements turn off.
