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.

Famous quotes containing the word lamp:
“With silent lips. “Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me.
I lift my lamp beside the golden door!””
—Emma Lazarus (1849–1887)
