>Researchers at MIT have shown that by surrounding the filament with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through.
Why can't/don't they use those same crystals on LED lights?
- fanf2 10y agoThe crystals reflect back heat in order to improve efficiency by keeping the filament hot. LEDs don't work by being hot.
- GigabyteCoin 10y agoThey do lose energy in the form of heat, though. Ever seen the massive heatsinks required for a high wattage LED to work?
