Help me with LEDs !

[tonygiang]

Hi dear all !

I want help me on this forum that : Which type of LEDs both captures and emits the most efficient light? Thank you very much !

LED = light emitting diode
Light capturing diode = photo-diode

by an-ode to cath-ode current flow

by an-ode to cath-ode current flow ! NO IT DOES NOT !

WHAT Get a life so in a cathode ray tube your theory is electrons travel from the positive final anode to the cathode where
the heater is ! that would result in no picture !

In a thermionic valve the heater aids the emition of freeing electrons !  to travel to the Anode! ...... it's the same flow direction Diode.

HA HA HA!

From wesleys thread : Kapitsa-Dirac and de Broglie : the final countdown 'light-wave dualism ' theorem

light not wave=heat  AG : your theme is thermo-voltaic or therm-ionic or thermo-acoustic related thermal noise

Yes so why are you saying the opposite ?
