PROBLEM TO BE SOLVED: To provide a lighting device, whose light source is installed to be detachable, capable of ensuring a power supply for detecting detachment/reattachment of the light source without driving a switching element of a lighting circuit for lighting the light source while the lighting circuit is on standby.SOLUTION: While a lighting circuit 20 is on standby before installation of a light source module 200, a light source detection section 160 detects whether or not the light source module 200 has been installed by a second control power supply Vcc2 supplied by a second converter circuit 50. Thus, a power supply of the light source detection section 160 that detects detachment/reattachment of the light source module 200 without driving a switching element Q2 of the lighting circuit 20 can be ensured. |
