description PROBLEM TO BE SOLVED: To provide a drive for a light emitting diode (LED) lamp capable of lessening the power to sense a severance in the LED lamp. SOLUTION: The drive of the LED lamp is structured so that a plurality of LEDs to constitute one LED lamp are divided into a plurality of groups and performs sensing of severance for each group, when the severance sensing is conducted on the time sharing basis for each group.
