<p>According to one embodiment, a lighting light source (12) including a current control element (41) and a voltage-dividing resistor (46, 47) is provided. The current control element (41) has a first main electrode, a second main electrode series-connected with respect to a lighting light source (16), and a control electrode for controlling a current flowing between the first main electrode and the second main electrode, and controls a current supplied to the lighting light source (16). The voltage-dividing resistor (46, 47) is parallel-connected with respect to the lighting light source (16) and connected to the control electrode, and inputs a voltage obtained by division of a voltage of the lighting light source (16) to the control electrode.</p> |
