PURPOSE:To provide a fluorescent lamp device and a lighting system where distortion of a globe is reduced and generation of a crack is prevented. CONSTITUTION:A partition disk 4 is fixed to one end of a cover 1 having a base 3 at the other end thereof. A lighting device 61 is contained inside the cover 1 divided by the partition disk 4. A fluorescent lamp 7 is secured outside of the partition disk 4, and is covered with a globe 8. The opening end of the globe 8 is joined to at least either one of the partition disk 4 and the cover 1 via a thermosetting adhesive 90. In this bulb type fluorescent lamp device, a hardness of the adhesive 90 is set to 20 or higher and 50 or lower. Consequently, the adhesive becomes more excellent in softness and elasticity than conventional. In the case where heat expansion or contraction is likely to be generated in the globe 8, it is possible to allow heat expansion or contraction, thus reducing generation of distortion in the globe 8 so as to prevent generation of a crack. |
