Punch the !ighting is a kinetic energy concept developed by designers Jun Bum Park Jin and Kim Sook that involves punching an LED lamp. Punch the !ighting was created to give people a fun way to release their stress. The lamp lights up when you hit it. The harder the hit, the more light it transmits.
It’s a cool idea because you can see how your body energy can convert to light instantaneously in a constructive, environmentally-friendly way.
