Most lightbulbs create light with a pair electrodes. Luxim does it with radio waves.
The Sunnyvale, Calif.-based start-up has come up with a way to get rid of the parts inside of high intensity discharge (HID) lamps that are often the first to fail. As a result, Luxim's LiFi (light fidelity) lamp provides more lumens per watt and lasts longer than competing products, according to the company.
In traditional HID lamps, high voltage pulses pass between two electrodes. The energy creates plasma from the ambient gases trapped inside the bulb and you get light. The electrodes, however, degrade … Read more
