ABSTRACT:
The present invention provides a lamp adapter, including a first adapter, a second adapter and a short-circuit. These two adapters are separately coupled between two incoming ends of T5 lamp and T8 socket. The first adapter contains a circuit board, and the second adapter is used for the coupling of the other pin pitch of the lamp. The short-circuit enables functional short-circuiting of the starter of T8 socket, so that the current from the power supply is fed from both ends of T5 lamp to highlight T5 lamp through the circuit of first and second adapters. The shunt circuit is arranged between the connecting circuit (of the input inductor and T5 lamp connector terminal) and cathode loop. The T5 lamp can be mounted onto the T8 socket without changing any structure and components, thus realizing energy-saving and environmental protection with higher intensity of illumination.
