    摘要: According to one embodiment, a lighting device includes a device board, a rectification device connected to a commercial power supply, a series LED circuit, and a transistor (current limiter) which limits a maximum current flowing through the series LED circuit. The series circuit mounted on the device board is configured by connecting in series a plurality of LED elements. Each of the LED elements lights when an output voltage of the rectification device is applied to the series circuit. A number of LED elements included in the series circuit is set in a manner that a voltage applied to the series LED circuit is 70 to 90% of the output voltage of the rectification device.
