To provide an LED integrated fitting lamp having a large capacity for an LED lamp.

The LED integrated fitting lamp 1 constituted of more than one to a plurality of LED lamps 3 mounted in a translucent outer cylinder 2, and is equipped with a current-carrying end part 5 communicating with an external power source at one end of the lamp 1; and a non current-carrying end part 7 at the other end. In order to prevent the LED lamp from breaking due to overcurrent, a current-limiting thermostat 12 which breaks a circuit with the excess current and reconnects the circuit when the current is reduced in temperature, or a fuse 13 which breaks the circuit with the excess current, an I-0 type ground-fault interrupter 14a, or an IGR type ground-fault interrupter 14b is mounted to the LED integrated fitting lamp 1 or conventional fluorescent lamp fittings so that the LED lamp 3 can be guarded by preventing overheat.
