There’s got to be a better way to make “swiveling” lamps to turning/rotating better. It has happened to me a few times that a “swiveling” lamp (one that rotates or turns) has eventually failed. The power chord that runs up the neck and out to the light bulb gets twisted up from all the times it has been rotated in a circle, and eventually it either gets so tight that it breaks or the “knot” that forms gets so big that the lamp structure cuts the power chord. The cut will either completely server the chord or expose the wires enough to cause it to short-out. I wonder if there is a lamp out there that does what I’m thinking, or if not, how come?
My idea would be for a lamp that had two “swivel” mechanisms that would allow the lamp/light to rotated without moving/turning the actual power chord inside. The swivel would be constructed to allow a power connection between two parts inside the swivel without any permanent connection – i.e. the original wire wouldn’t continue through the swivel “joint.” There would be one at the base of the lamp. From there, an internal wire would run up the neck to the next swivel joint where the light actually rotates. Then a new internal wire would run from there to the light or any other swivel joints as necessary – so on and so forth.
The trick is to allow enough electricity to pass through consistently while still be contained within the swivel so as not to release electricity out side the device and cause shocking.
For now I picture the swivel constructed with two small concentric metal/copper thin circles – basically like a small, thin washer. As the power chord comes into the swivel joint, the wire splits into two, separating the positive and negative wires. Each wire would connect to one of its respective copper rings. On the other side of those rings would be matching copper rings which then connect to the corresponding +/- wires and continue on from there. I guess there would be small ball bearings to allow the swivel. To protect against shocking, there would be rubber casing around the whole thing. It might need some additional rubber between the 2 concentric rings on each side to prevent crossover and shorting.
It might be difficult to keep the size of the whole thing small. I’m not sure how much rubber would be needed to fit in between to prevent the crossover. I still don’t understand why it hasn’t been done. I guess the size, price, and possible complexity could hold it back. Actually, I don’t think it would be that complex. Anyways, I’ll add a drawing later to better depict what I’m talking about.
