ABSTRACT:
A power supply includes a light source, a signal converting unit converting an externally supplied AC voltage into a DC voltage, a DC-DC converting unit converting a magnitude of the DC voltage, and a light source protecting unit. The light source protecting unit outputs the DC voltage of a predetermined range as a light source driving voltage to supply a stabilized source driving voltage to the light source and suspending an application of the light source driving voltage to the light source when a magnitude of the light source driving voltage is larger than a predetermined value, based on an externally supplied control signal.
