PURPOSE:To control moderately the light irradiation to one side with the simple structure and facilitate the lamp exchange by positioning and fitting the connecting part of a socket to the lower surface side, and providing a base, in which connecting pins vertically projected in outline to the luminous tube surface is provided, in the recessed part to be engaged with the main frame of the socket. CONSTITUTION:A socket fitting stand 6 is internally provided in the main frame of a box-shaped illuminator having the supporting material fitting part 3 at one end and having a projection opening 2 at the lower surface. A recessed part 19 to be engaged with the main frame of the socket 9 is provided in one side surface of a base 16 of a lamp 13, and four connecting pins 20 to be connected to the connecting part 11 of the socket 9 are provided in parallel-crosses shape in outline and projecting vertically in outline to the surface of a luminous tube 14. The lamp 13 can be mounted by pushing up the connecting pins 20 to the upper and connecting it to the connecting part 11 of the socket 9. At this stage, a rising part 7 provided in the socket fitting stand 6 can be mounted as a guide for positioning. Thereby, undesirable light leakage can be satisfactorily prevented, while the connecting operation can be facilitated. |
