Editor's Notes
- Once again, ladies and gentlemen, good evening. Tonight we are to discuss
- 1. LED (Light Emitting Diode) is a semiconductor device that produces a range of visible light when an electrical current passes through it 2. Semiconductors are materials with ability to conduct electrical current
- 1. Incandescent Lamp – heats up a thin wire to produce light 2. Compact Fluorescent Lamp – dissolves mercury to produce light 3. LED Lamp – uses a semiconductor diode to produce light

- Thermal Management – conducts heat away from the LED using a heat sink and then moves it away from the lamp.
- Driver – an electronic device that provides the correct current and voltage to the LEDs for proper operation.
- Array - an array is composed of several chips or emitters, mounted to a printed circuit board to emit light.
- Optics – May be a lens, diffuser, reflector or a combination. Can be made of glass or plastic. Efficiently distributes the light coming from the LEDs.
