3.5 Extraction of a Heat from LED

Did you know? Generic structure of LED light source consists of an LED chip, a printed circuit board, and a cooling system attached:

  • LED chip
    source of a light and a heat
  • printed circuit board
    electrical connection to LED chip
  • heat sink
    enhances heat dissipation by conduction and convention
LED cooling
  How it works? When power up the LED chip, visible light and the heat are generated. The heat is extracted from LED chip by printed circuit board, heat sink, and subsequently released to the atmosphere.
