Winding String Dimmer

apparatus for controlling a light

The Winding String Dimmer light is so named because it uses the process of winding and unwinding a spool of string to control the strength of a light source.

When you slide the control towards "brighter", the spool of string engages with a low speed motor contained underneath the device, and unwinds the string wrapped around the bulb.

When you slide the control towards "dimmer", the bulb engages with the motor and winds string from the spool up the shaft of the bulb, concealing more of the light.

The use of coloured string results in the emission of a variety of tinted lights.

It's easier to understand if you view the simple illustration in the link:

       Which color light goes best with charcoal?

       Doesn't make much sense for a lightbulb which can have an electrical dimmer, but would absolutely work for a candle in a jar. A dimmer for a candle with that mechanism would be kind of cool.

       To save having to rotate the bulb (not that it's difficult), have the spool on an arm which rotates around the bulb, with a simple cam mechanism to control the height for smooth wrapping.

       Creates a rotating shadow if you do that. Believe me; I recorded several versions of achieving a mechanical dimmer control for a light bulb before settling on this one.
xenzag, Nov 25 2021
  

       True enough.

       Do you not have LEDs yet, [Rayford]?

       Okay, well done then. Sometimes I forget about art being a thing.
doctorremulac3, Nov 25 2021
  

       Not art. Halfbaked idea :-) Art version would feature a room full of these, all operating randomly.
xenzag, Nov 25 2021
  

       I do have LED's. Even ones on dimmers. But nothing about the idea mentions them.

       Might be kind of relaxing to watch.   

       The single one, the room full might be kind of stressful.

       So THAT’S why he came into the shop yesterday and bought up all of our string!

       I kept seeing "Winding String Dinner", and thought this was about someone playing the harp while you eat or something.

       Not if the arm/spool is mounted on an annular bearing above the bulb, with just the final string guide at the correct height.

       An orbiting spool also requires a much larger footprint than an oblong box. I had also considered an expanding and contracting latticed sleave that enclosed a similarly shaped light bulb to the one depicted.

       //expanding and contracting latticed sleave//
See, now THAT'S more like it. Hoberman-sphere-esque...
neutrinos_shadow, Nov 29 2021
  

       Hey, that's not what xenzag originally spec'd, but I'd bun a Hoberman light dimmer. Could absolutely see it as part of an art installation.
