I have set up a small solar array, controller and a storage battery. I wanted to make some low power lighting that I can use in my office that would not consume a lot of power.
I had a bunch of scanner parts lying around and decided to put them to good use.
Step 1: Get Your Parts
1. Scanner Head
2. 6' Lamp cord and switch - $3.99
3. Low voltage lighting base - 2 for $5.95
4. PVC 1" adapter threaded on one end, slip to fit on the other - $.87
5. 12" x 1" diameter PVC threaded pipe, (nipple) - $1.12
1 1/4" hole saw
hot glue gun
solder iron & solder
Remove the lens and camera electronics and save for your next project.
Keep the displayed power circuit in place on the scanner head.
Step 2: Trim the Low Voltage Base
Rotate the base and trim all the ridges.
Step 3: Remove Upper section from Base Plate
The 1" PVC adapter will not fit unless you remove this section.
Step 5: Attach and Trim PVC Pipe
I trimmed my pipe to 12" from the base plate. You can adjust yours to fit your needs.
Lower for brighter focused light, Higher for wider disfused light.
Step 6: Remove reflector side of Scanner Head
Remove the screws and carefully remove the base plate.
Be careful not to damage the light tubing when you remove the cover.
Notice the light tube reflectors that run along the slot for the light tube.
Step 7: Length Measurment
Step 8: Measure center point for drill hole
Step 9: Drill your mounting hole
You will need to drill an 1 1/4" hole in the base plate.
This hole is slightly under sized. You will need to file the hole slightly larger to fit the PVC pipe.
I used an old soldering iron to enlarge the hole.
Step 10: Install the Scanner Head
After hot gluing, turn the lamp right side up and make sure that the scanner head is aligned.
It takes a minute for the hot glue to cool enough to become solid. This will give you plenty of time to align the scanner head.
Step 11: Trim the Power Circuit wires
Step 12: Solder the lamp Cord
Be sure that you run some heat shrink tubing onto the leads before you connect the leads.
After soldering slide the heat shrink tubing on to the bare sections of wire and heat with the soldering iron to secure the connections.
Step 13: Finish Up
You may want to attach the lamp cord to an AC to DC adapter.
Notice the voltage and current readings on my power supply.
The lamp is running off of 12 volts and consuming 370ma of current.
The lamp could be just a bit brighter, for my taste, but it is enough light to read by.
I am thinking of adding a second light tube and power supply from another scanner head that I have.
