Light - Emitting Diode (LED) is a solid - state light source with electroluminescence via the semiconductor PN junction. It uses electron - hole recombination to excite photons, boasting high electro - optical efficiency, long life, and fast response. Core principles: ① Semiconductor emission: Current through PN junction makes N - region electrons and P - region holes recombine, releasing energy to excite phosphors (e.g., blue LEDs + yellow phosphors for white light). ② Quantum well design: InGaN/GaN multiple quantum wells raise luminous efficiency to over 200lm/W (vs. 15lm/W for incandescent lamps).
