  In addition, a G5 base 2 having a bottomed cylindrical shell made of aluminum having an outer diameter of about 15 mm and a length of about 11 mm is joined to the sealing portions at both ends of the bulb 1 through an adhesive. However, an external lead wire led out from the stem is connected to a pair of terminal pins protruding from the bottom of the shell, and a straight tube type fluorescent lamp with a total length of lamp (including the base of both cap shells) including this cap 2 is about 1,200 mm. A lamp L is formed.

  Moreover, D1 is a lighting fixture and is provided with multiple sets, for example, 2 sets of housings 3 and 3 here. The casing 3 is formed of a cylindrical body having a rectangular cross section made of a steel plate coated with a white surface. The fluorescent lamp L is supported in the vicinity of one end of each side of the casings 3 and 3. Socket devices 4 and 4 for electrical connection are arranged facing each other.

  The pair of socket devices 4 and 4 are formed of an insulating-coated metal plate or a synthetic resin material, and correspond to positions 2 and 2 at both ends of the straight tube fluorescent lamp L (the straight tube fluorescent lamp L). It is fixed by screwing, engagement of protrusions, flanges and recesses, or adhesive or adhesive tape.

  In addition, a high-frequency lighting circuit device 5 using, for example, an electronic ballast (inverter) is provided in the housings 3 and 3 corresponding to the respective fluorescent lamps L, or connected to the socket devices 4 and 4. A lighting circuit device 5 for two lamps is provided in one housing 3. In the figure, 51 is a feed line, and 31 is a feed line insertion hole.

  Although not shown in the drawings, holes and projections for attaching the casing 3 to a ceiling, a wall, a column or the like are formed on the side surface of the casing 3 where the socket devices 4 and 4 are not provided, and screws or the like. It is fixed by using.

  It is a common practice to provide the housing 3 with a pair of socket devices 4 and 4. However, in the lighting fixture D1 of the present invention, the housing 3. Are connected via a connecting member 6.

  That is, in the luminaire D1 shown in FIGS. 1 to 4, each piece 62, 62 of the hinge 61 is a screw 64, as a connecting member 6 that connects the two housings 3, 3 near the end portions of one side surface. ... is installed.

  When the pieces 62 and 62 of the hinge 61 are overlapped in the state shown in FIG. 3 with the shaft 63 as the center, the casings 3 and 3 are arranged in parallel, and the overall length of the lighting fixture D1 is the shortest.
