ABSTRACT:
The invention herein relates to a kind of improved floor lamp dimmer and the improvements include the electronic components required by the dimmer circuit enclosed in an oblong case, which is then installed inside the column of the floor lamp; moreover, there is a slot in the case and the column for the placement of an operating bolt which is linked to slide-type lever of the rheostat; the aforementioned operating bolt can be moved upward and downward along the the outside of the floor lamp column, thereby serving as the power switch and brightness adjuster; the dimmer is enhanced in that the design includes an LED indicator which is connected to the electrical circuit of the floor lamp and is capable of outputting a light signal, thereby making it possible to find the location of the dimmer in the dark.
