Trap Development: Hacking a Chinese Garden Lamp for Use as a UV LED Power Supply for Coconut Rhinoceros Beetle Traps

Cheap Chinese garden lights have some features which make them ideal for use as power supplies for UV LEDs being tested on CRB traps:

  • ruggedized, water resistant
  • solar powered rechargable battery
  • LED turns on at dusk; just in time for the CRB flight period
I tried replacing the white LED that come with the unit with one of our UV LEDs. It works!
To make the LED omnidirectional, it is simply a matter of scuffing the plastic lens with 400 grit sandpaper to turn it into a diffuser.
Here's an interesting YouTube article explaining how the cicuit works:
