PROBLEM TO BE SOLVED: To prevent an error in fitting a luminescent lamp and forgetting removal of a protective cover. SOLUTION: The surface of the luminescent lamp is protected by the protective cover 10 so as to reduce a damage that is caused even when the luminescent lamp containing an enclosed high-pressure gas bursts during transportation. The protective cover 10 is provided with an IC chip 6, which retains information on the luminescent lamp. The information is read out of the IC chip 6 when the protective cover 10 is fitted to the lighting device, this preventing an error in fitting the luminescent lamp. As removing the protective cover 10 breaks the IC chip 6, it makes impossible to read the information out of the IC chip 6. Thus, removal of the protective cover 10 is detected to prevent forgetting removal of the protective cover 10. COPYRIGHT: (C)2007,JPO&INPIT
