Abstract:
1. A driver for amplifying an operating voltage of a luminary, comprising: a driving circuit providing a first signal; and a negative multiple voltage circuit electrically connected to said driving circuit and said luminary respectively for transforming said first signal into a second signal to be transmitted to said luminary, thereby said luminary being driven in response to said second signal; wherein said negative multiple voltage circuit further comprises: a first capacitor electrically connected to said driving circuit; a first diode having an anode electrically connected to said first capacitor and a cathode grounded; a second diode having an anode and a cathode electrically connected to said first capacitor and said anode of said first diode simultaneously; and a second capacitor having one terminal electrically connected to said anode of said second diode and said luminary simultaneously and another terminal grounded.
