Patent ID: 7514881

Claim:
A discharge lamp lighting apparatus comprising: a power section operating to generate a high voltage to be applied to a discharge lamp to trigger electrical discharge within said discharge lamp and to generate an AC voltage to be supplied to said discharge lamp to keep said discharge lamp in a stable lighting state; and a control section controlling operation of said power section; wherein a power circuit board on which said power section is mounted and a control circuit board on which said control section is mounted are installed separately within an enclosure of said discharge lamp lighting apparatus, wherein said control section is constituted by at least an integrated circuit, a resistor, a capacitor and a transistor mounted on a control circuit board, wherein said power section includes an inverter circuit for generating said AC voltage and a starter circuit for generating said high voltage, wherein circuit elements constituting said inverter circuit of said power section are mounted on a power circuit board, and wherein said control circuit board and said power circuit board are connected to each other by wire bonding in order to electronically connect said control section and said power section with each other.
