Step 6: Putting It All Together

Now that we have covered the major pieces of this project, it's time to put it all together.

You are going to want to attach the LEDs to some sort of heatsink, as they tend to get hot.  I mounted them onto spare TO-3 size transistor heatsinks, and then press-fit the fins of the heatsink onto another piece of drywall corner bead hot-glued to the base of the lamp. This gives the LED light a good exit angle for getting out of the lamp (so the light disperses around the room).

Stash the power supply in the corner or on the edge of your lamp where you have the best frame strength.  The circuit card is pretty light, and can be hot-glued anywhere.

I mounted my IR sensor in the middle of the lamp by cutting a hole in the cardboard and hot-gluing it in place.  I didn't have to cut a hole in the fabric outside because it was so thin the IR light went right through it.

Attach a piece of string to each corner of your lamp, tying it through a couple holes in your corner bead frame.  

How you attach it to the ceiling is a matter of personal preference.  Make sure you mount it to the solid ceiling joists so it doesn't fall down and break!  See the attached picture for my method - I made four custom hangers which I nailed into the ceiliing, then tied the string onto a washer which catches on the hanger.

You will also need to get power to your lamp.  For a long time I used an extension cord run discretely up the wall.  Recently I installed an always-on AC outlet above the lamp.

Put it all together, and there you go - a giant ceiling-mounted  remote-controlled RGB LED moodlight!
