Wireless LED project Answered

i'm working on a project where i need a circuit board with about 15 LED's. But i need to have a switch turn them from a very shot distance, about 3 to 5ft. so i CAN NOT have any wires, and dont want wires. So i already assume a power supply should be mounted on the circuit board, and at the switch. But i don't know what else i need. Is there a tutorial i can find ? Could i get some help ?

I have an idea, make this project:

Then you will have to find a way to increase the range. WARNING the NPN transister WILL get very hot if left on for 1 min, so use less time.
