    Publication number: 20120286668
    Abstract: 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.
