A linear lighting fixture is placed horizontally.

[Problem to be solved by the invention]

In the prior art as described above, since the brightness is low near both ends of the lamp 2, uneven brightness occurs on the surface of the panel 8, which is unfavorable in appearance and also reduces the illuminance of the surface to be irradiated (such as a desk top). There was a problem with the lack of balance. In order to solve this problem, as shown in FIG. 6, a groove-shaped instrument body 21 with an inverted U-shaped cross section and open ends
A pair of lamp sockets 23.24 for supplying power to one lamp 22 are arranged in each fixture main body 21, and in the vicinity of the lamp sockets 23.24, the lamp 22 and other It is conceivable that each end of the lamp 22a and the like are lined up. That is, lamp 22.22
By overlapping each end of the two lamps 22 and 22a, which are arranged offset in the longitudinal direction of the lighting fixture, the brightness near the end of the lamp 22a can be adjusted to a level close to the brightness at the center of the lamp 22. It is intended to compensate for this. However, in such a configuration, in order to ensure that the lamp 22 having a certain tube length is attached to the lamp sockets 23 and 24, it is necessary to adjust the distance between the lamp sockets 23 and 24, which are respectively fixed to different fixture bodies 2l. needs to be set accurately. However, due to manufacturing variations in the device body 21 and problems such as construction accuracy, the socket 23. It is expected that it will be extremely difficult to accurately set the positional relationship of the lamps 24 to the desired state, and problems such as the lamp 22 not being able to be installed or poor contact between the lamp 22 and the bottle may occur. It is possible, but it is difficult to realize it. An object of the present invention is to provide a lighting fixture that can solve the above-mentioned technical problems and realize a well-balanced lighting condition.
