[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus using a single-ended lamp.

[0002]

2. Description of the Related Art Conventionally, in a lighting apparatus using a straight tube fluorescent lamp having a long specified lamp length, such as a 110 W straight tube fluorescent lamp having a substantially straight discharge path, the lamp length is limited. Correspondingly, the length of the fixture is long, there is a problem in handling, and in order to increase the brightness, two straight tube-type fluorescent lamps must be installed side by side. There is a problem.

Further, as described in, for example, Japanese Patent No. 2649108, there is a lighting fixture using a single-ended lamp having a substantially U-shaped discharge path. Compared to a lighting fixture using a straight tube fluorescent lamp, it is about half as short, and handling is improved. By arranging such lighting fixtures in a straight line using, for example, two lighting fixtures, the lighting fixtures can be installed in place of one lighting fixture using a straight tube fluorescent lamp.

[0004]

However, in the case of a lighting device using a single-base type lamp, the size of the lighting device using a straight tube fluorescent lamp can be reduced one by one in the longitudinal direction of the lighting device. In the case where two lighting fixtures using one-sided lamps are installed instead of one lighting fixture using a straight tube fluorescent lamp, these two lighting fixtures are replaced by one.
They must be installed individually for each stand. The installation place of the apparatus main body is located at a high place such as a ceiling surface, and the worker climbs on a stepladder or the like. Therefore, there is a problem in workability such as frequent climbing and descending.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has been made in consideration of the above problem.
An object of the present invention is to provide a lighting fixture with improved workability by enabling installation at any time.
