Introduction: UV LED Solar Light Modification
Change a yellow or white light solar path light to an Ultra Violet Path Light.
Step 1: Take a Solar Path Light and Remove the Top From the Clear Globe
--DO NOT look directly into a UV led when it is on...EVER. UV light is dangerous to unprotected eyes so throw on a pair of UV blocking sunglasses for this project--
Take the top off the solar light and place it on your workbench solar cell side down. This should cause the led to light up and shine into your face. If it is not on figure out where the photo cell is and tape over it to trick it into thinking it is night. You will need to have the light ON. When you have the light on use your wire cutters and snip off the LED.
Step 2: Polarity Check and Solder
Take your UV LED and touch the two wires that are now exposed from the light to the two ends of the LED. If it does not light flip it over so the ends(long and short) are reversed. LEDs are diodes and as such they will only allow current to flow one direction. Knowing that the light was ON when you cut it you can assume there is power(1.5 volts) in these exposed wires.
Step 3: Solder
Once you have a lighting diode you can solder it. Don't worry about the power being on it is only 1.5 v
Step 4: Paint It GLOW IN THE DARK
Step 5: Put It All Together
Put the painted glow tab in the cup and put the light on top of it. Turn out the lights!
You can use the patio light's original globe and paint the insides of it if you like also. I am using a glass votive cup here.
We have a be nice policy.
