摘要： An illumination apparatus including: a power supply circuit which outputs a DC power obtained by rectifying an AC voltage and stepping up the rectified voltage; a light source unit having semiconductor light emitting elements turned on by the DC power; and a housing formed of a conductive material that is grounded through a ground path and on which the power supply circuit and the light source unit are mounted. When one of power feed lines is cut off, the light emitting elements are supplied with an AC power from an AC power source through the ground path and a stray capacitance formed between the light source unit and the housing, and a forward voltage of the light emitting elements has a light emission level hardly recognizable.

摘要： A lighting device includes a plurality of LED light sources, an LED substrate mounted with the LED light sources, and at least one protector element mounted on the LED substrate to protect the LED light sources. The LED light sources are divided into a plurality of LED light source groups. The protector element is arranged in at least one of the LED light source groups while being electrically connected to the LED light sources of each of the LED light source groups.
