PURPOSE: A high intensity LED fluorescent lamp is provided to turn on a high intensity LED fluorescent lamp by using a charged battery power source part. CONSTITUTION: An on/off switch(11) switches power according to normal power. An AC-DC power converter(10) converts an AC voltage into a DC voltage when the switch is turned on. A battery receives the converted DC power when the switch is turned on. A battery is connected to a charger circuit(20). A changeover switch(50) is connected to the AC-DC power converter when the switch is turned on. The changeover switch is connected to the battery when the switch is turned on. A sensing circuit(30) senses whether power is disconnected and the switch is turned on. A control part(40) controls the location of the switch according to the signal of the sensing circuit. A high intensity LED fluorescent lamp(60) is connected to the changeover switch. |
