IPC: H05B45/50
Filed: 2010-12-20
Abstract: PROBLEM TO BE SOLVED: To prevent an LED lamp failure by restricting current flowing through the LED lamp when the LED lamp is inserted to a lamp socket.SOLUTION: During unloaded condition, if voltage more than or equal to the rating voltage of a LED lamp 110 has been output from a power conversion part 2, excessive current exceeding a rating value may flow immediately after the LED lamp 110 is connected to a lamp socket 120. However, in the LED lighting device of the present embodiment, a controller 5 stops operation of the power conversion unit 2 until a connection determination unit 6 determines for connection of the LED lamp 110. Then, when the connection determination unit 6 determines the presence of the connection (loaded condition), the controller 5 starts the operation of the power conversion unit 2. Therefore, since the voltage more than or equal to the rating voltage is not applied to the LED lamp 110, and the current flowing through the LED lamp 110 when the LED lamp 110 is inserted to the lamp socket is restricted, failure of the LED lamp 110 can be prevented.
