Web17 de abr. de 2024 · By definition, LED refers to light emitting diode, which means they are made up of small diodes created from semiconductor materials. The trick is to have varying levels of electrons in each layer of a diode, so one layer may have depleted electrons while the other will have excess electrons. WebAn even coating of yellow phosphor in a silicone resin binder material converts the blue light generated by the LEDs into light approximating white light of the desired colour temperature —typically 2700 K to match the warm white of an incandescent bulb.
