It´s an old 200Watt stained bulb where I removed the inner parts.
I replaced the inner parts by 10 RGB LEDs with automatic colour changing.
Yo can mount such a bulb on a stand like picture one or put it into a nice box like on licture two.
Have fun and lets see how to build it.
Step 1: The parts...
- An old bulb (never again throw bulbs away) ;-)
- Colour changing LEDs
- Some small aluminium tubes (used for the end of flexible wires)
- Some copper fittings an tubes
- A switch
- A battery holder
- Some wires
- Some glue
- Two component clay
- Shrinking hose
Step 2: Preparing the bulb
Picture 1 shows 2 LEDs crimped together. You can use solder as well. But crimping is a bit easier. ;-)
Use shrinking hose to insulate it and solder wires at the end.
All LEDs are parallel connected and they need 3V without any resistor!
If you are finished, just make a test, attach 3V: CLICK
Use two component clay to fix it inside the bulb.
If you attach power it looks like this: CLICK
Step 3: Put it into a case or build a stand
To do so you have to prepare a base plate.I used "Multiplex".
I drilled a hole for a switch and on hole for a copper tube (22mm).
I used wax stain to stain and polish the wood.
Than I soldered the tubes and fittings together, polished them.
The long tube will be the battery case.
