PROBLEM TO BE SOLVED: To suppress decease of luminous fluxes and deterioration of appearance and easily insulate a lighting circuit by providing a partitioning member positioned between a light emitting tube and a lighting circuit and provided with a metal member face to face to the light emitting tube and a resin member face to face to the lighting circuit. SOLUTION: A fluorescent lamp apparatus 1 is attached to an appliance main body and when electricity is applied to an inverter circuit 15, a light emitting tube 22 is turned on. A partitioning plate 5 to partition the light emitting tube 22 and the circuit 15 is produced by joining a resin member 5a and a metal member 5b. Since the metal member 5b is set face to face to the light emitting tube 22, worsening and deteriorating of appearance of the partitioning plate 5 due to light rays and heat from the light emitting tube 22 can be suppressed and by keeping the reflectance of the partitioning plate 5, the lowering the luminous fluxes can be suppressed. Moreover, since the resin member 5a is set face to face to the inverter circuit 15, even in the case the inverter circuit 15 is brought into contact with the partitioning plate 5, no electric communication is produced and the circuit is easily insulated and at the same time noise generation, which is easily caused by resonance of a lighting circuit in the case a metal plate is adjacently installed in the lighting circuit such as the inverter circuit 15, can be suppressed. |
