とができる。As described above, in the LED lighting device according to the first aspect, since the LED body can emit light of relatively high luminance at a low current by the LED body, a long life and a reduction in power consumption can be achieved. Since mercury does not adhere to a broken elongated tube like a conventional fluorescent lamp, disposal can be performed safely and easily. Further, since the rotation of the LED lighting lamp is prevented by the rotation preventing means provided on at least one of the base and the bushing, the emitted light is directed in the same direction even if there is only one electrode pin at each end.

Since mercury does not adhere to the elongated tube that has been damaged, it can be safely and easily disposed of. Further, since the LED bodies of the first LED series circuit and the LED bodies of the second LED series circuit are alternately arranged on the printed circuit board along the longitudinal direction, the LEDs of the first LED series circuit
When the body is cut, or when the LED body of the second LED series circuit 26 is cut, the LED bodies on the printed board are turned on and off alternately, that is, all the LED bodies on the printed board are not turned off. , Can be continuously used while maintaining a state in which the whole is uniformly lit.

業の労力を軽減して生産性を向上できる。Further, in the escalator according to the third aspect, since the LED body can emit light of relatively high luminance at a low current, power consumption can be reduced. Also,
The use of an LED body eliminates the need for a ballast that boosts the AC voltage and wiring for it, and also extends the life of the lighting device, thus reducing the frequency of step-detachment work associated with replacing LED lighting. It is possible to reduce the labor for escalator maintenance work and improve productivity.

きるエスカレータが得られる。Further, in the escalator according to the fifth aspect, since the plurality of LED units are arranged in a line along the moving direction of the plurality of steps, when the plurality of steps move at a constant speed, the gap between the adjacent steps is determined. The outgoing light propagates through. This allows the emitted light to be transmitted to the passenger in an intermittent state, even though the getting-on / off warning LED body is continuously lit. Therefore, the escalator according to claim 6 can further evoke the passenger's attention. In the escalator according to claim 1, a plurality of LED lighting lamps according to claim 1 are arranged side by side, and rotation preventing means provided on at least one of the base and the bushing. Thus, the rotation of the LED lighting is prevented, so that an escalator capable of directing the emitted light in the same direction even when the LED lighting has only one electrode pin is obtained.
