Patent ID: 8067895

Claim:
A lamp adapter, comprising: a first adapter, being comprised of a T5 lamp coupling hole and a T8 socket connecting pin and being coupled between a first incoming end of said T5 lamp and a first supply end of said T8 socket; a second adapter, being comprised of a T5 lamp coupling hole and a T8 socket connecting pin and being coupled between a second incoming end of said T5 lamp and a second supply end of said T8 socket, said second adapter coupling of a pin pitch of the second incoming end of said T5 lamp; a short-circuit, having an insertion end identical to a starter of T8 socket, being assembled on the coupling portion of the starter of T8 socket, bringing about functional short-circuiting of the starter of T8 socket with the short-circuit, the T5 lamp have both ends supplied by current from the power supply to highlight T5 lamp through the circuit of first adapter and second adapter; a circuit board, being assembled within said first adapter, being fitted with a bridge rectifier, power factor correction circuit, high-frequency and DC common territorial circuit, and being comprised of two T5 lamp connector terminals, two T8 lamp connector terminals, an anode loop, a cathode loop, an input inductor, the input inductor being arranged between T5 lamp connector terminal and anode loop; and a shunt circuit, being arranged between a connecting circuit of the input inductor and T5 lamp connector terminal and the cathode loop, the cathode loop being provided with a capacitor.
