It is not necessary, but relates to a ballast hanger member of the configuration that can be easily grafted to the existing street light.

As is well known, a lamp commonly used in a street lamp is a discharge lamp that emits light by discharge in a low pressure mercury vapor. As a general property of a discharge lamp, when a current flows, a voltage required for discharge drops, thereby causing a discharge by applying a constant voltage. In the above process, if the current is excessively increased, the lamp may be destroyed, so that the stabilizer is provided to prevent the current from increasing.

Such ballasts are usually formed inside the lamppost at a certain height and then installed in the interior of the lamp. In the conventional ballast, when the ballast is manufactured, the ballast is hooked to a pre-configured bolt or the like by using a hook formed at the top of the lamp. At the same time, a board is provided around the ballast for fixing the disconnect switch and the wire connection terminal.

However, according to the conventional installation structure, there was a problem that replacement, inspection, repair, and installation of the ballast was very difficult, because the parts such as the disconnect switch and the terminal for connecting the wire to the ballast were connected by wires. However, because the weight of the ballast itself is heavy, if you do not hold the ballast, the wires may fall out or come into contact with street lamps or the human body by the weight of the ballast.
