NettetEach recombination radiates light or Photons. LED's do have a polarity and hence do not work if they are connected in Reverse bias. The easiest method to check the polarity of common LED is by holding the LED close to your eye. You will see that there are two electrodes. The thicker one is the Cathode(-). Light is emitted from the Cathode.

Nettet3E) Determine if your LED tube light is compatible with the shunted or non-shunted tombstone configuration. If your LED tube light is single-ended, it is NOT compatible with shunted tombstones. This is because each of the two contacts in the tombstone must be opposite polarity for a single-ended LED tube light to work. NettetLEDs.
