LED lamp, LED lighting device, LED lamp lighting apparatus, and LED lighting system

摘要

The object of the present invention is to provide a LED illumination system which does not cause heat generation and damage, even when a straight-tube fluorescent lamp is mistakenly fitted into a straight-tube fluorescent lamp luminaire in which the fluorescent lamp ballast has been replaced with a LED lighting device. The LED illumination system according to the present invention is configurated in such a manner that the LED lighting device is installed in an existing straight-tube fluorescent lamp luminaire, and the LED lamp is connected to the existing sockets. The characteristic of the output from the LED lighting device connected to either inter-terminal section A on the ends of the LED lamp is to be different from that of an existing fluorescent lamp lighting device. The LED lamp is provided with lighting device output detection means for detecting the output from the LED lighting device and also with protection means for cutting off the input to the LED lamp when the output detected by the lighting device output detection means is outside of a predetermined range.
