Thread: Work light el cheapo conversion to LED

I had to change the bulb on my work light and discovered the reason behind its poor performance, the reflector was heavily corroded.



Splitting the glass from the reflective part is easily acheived by applying heat from a heat gun and a prying with a thin blade.



The source of the LED lights is burned LED light bulbs commonly found these days at homes and offices. You need to cut the wires that link the disc carrying the LEDs from the electronic circuit board at the board side.



They are supplied either for 12V or 220V dismanteling the bulb is easy and is covered by this video

You will need a piece of aluminum to act as a cooler for the LEDS and a base for the construction. I measured the distance between the base of the Halogen bulb and the glass to select the appropriate aluminum plate thickness that places the LEDs at the same distance.

Place as many LED units s you can fit on the aluminum base, make sure to use thermal paste between the LED units and the base.



Parallel Connection is requiered, all RED(+) wires connected together and BLACK(-) wires with BLACK wires together.



Test the system before soldering the wires. Proceed to finalize your work by isolating the wires and linking them to the light plug socket paying attention to the polarity.



All is left is to re-assemble the work light making sure to waterproof it with silicone.

Voila!

The led emitters don't need a reflector.
