Ceravision - Electrodeless Lamp

Electrodeless Lamp

Electrodeless lamps have been recognized, since Nikola Tesla filed a patent in 1894, as having a number of advantages:

• No electrodes to break - so potentially very long life
• No chemical degradation of the electrodes - so much lower lumen loss and discoloration during life
• No reactive metal inside the bulb - so the ability to use much more efficient fill materials

The main problems have been constraining the radio waves within the lamp, and generating RF power at low cost.
