DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting fixture in which a pair of straight tube lamps are installed.

[Prior Art] Conventionally, in a lighting fixture in which a pair of straight tube lamps are internally installed in the main body of the apparatus, the straight tube lamp may be attached, for example, as a sixth example.
As shown in the figure, one end of the straight tube lamp 1 is inserted into a socket 7 provided at the end of the fixture body 3, and the other end of the straight tube lamp 1 is attached to the fixture body 3 by rotating the socket 7. It is attached by engaging with the support tool 2 attached to the end. When attaching the straight tube lamp 1 to the support 2, each straight tube lamp 1 is held by a holding portion 8 formed in a substantially U shape as shown in FIG. 1 is attached to the support tool 2 so that 1 is lined up left and right. By the way, the light distribution of the pair of straight tube lamps 1 is in the orthogonal line direction b orthogonal to the straight tube lamp 1 rather than the extension line direction a of the straight tube lamps 1 arranged in parallel as shown in FIG. The one with more light distribution. Therefore, when the pair of straight tube lamps 1 are arranged horizontally as shown in FIG. 7, the degree of lateral illumination of the luminaire A is low, and the straight tube lamp 1 is vertically moved. It is arranged vertically so that they are arranged side by side. And in this thing, a pair of straight tube lamps 1
By arranging the support tool 2 supported by the mounting tool 16 in the vertical direction, the straight tube lamp 1 is arranged in the vertical direction together with the support tool 2. As shown in FIGS. 9 and 10, the connecting portion 4 of the support 2 is attached to the lower end of the inverted L-shaped mounting base 16 by the fixing tool 17, and the upper end of the mounting base 16 is fixed by the fixing tool 17. It is attached by being connected to the inside of the instrument body 3.

[Problems to be Solved by the Invention] However, in the conventional example as described above, in order to arrange the straight tube lamp 1 in the vertical direction, it is necessary to use the mounting base 16 which is a separate member from the support tool 2. Therefore, the cost of parts is high, and it is necessary to mount the support tool 2 on the mounting base 16 and the mounting base 16 on the fixture main body 3 at the time of mounting, which increases the number of man-hours for mounting work. Then, there was a problem that it took time to install. Further, when the straight tube lamp 1 is turned on, the light from the straight tube lamp 1 is largely cut off by the support tool 2 and the mounting base 16, and the shadow of the support tool 2 is generated as shown in FIG. 10 (b). The shadow a of the mounting base 16 is clearly reflected on the translucent cover 5, and there is a problem that the appearance is deteriorated.

The present invention is intended to solve the above problems, and an object thereof is to prevent the lamp light from being cut from a straight tube lamp as much as possible and to save a support tool for holding the straight tube lamp without trouble. It is an object of the present invention to provide a luminaire which can be mounted in the main body of the luminaire, and in which the work of inserting the straight tube lamp into the support is facilitated.
