PURPOSE: A power cable support of a light device for an apartment house is provided to fix the power cable in a concave part of a slide block through the rotation of a rotation block. CONSTITUTION: A support frame is fixed in an outer wall of an apartment house. A slide block is movably combined in the support frame. A rotation block is rotatably combined in the slide block. A reducer is arranged in the slide block. A brake controls the movement of the slide block and includes a coil(51), a plunger(52), an elastic spring(53), and a transformer. The plunger moves by the magnetic force of the coil. The elastic spring elastically supports the plunger to the direction of the support frame. The transformer boosts the DC electricity inputted to the power cable. A light device is fixed in the support frame to perform the light emitting function. |
