1. Types of Light Production

2. The production of light as a result of high temperature
Incandescence
The production of light as a result of high temperature

3. Electrical Discharge
The process of producing light by passing an electric current through a gas

4. Phosphorescence
The Process of producing light by the absorption of ultraviolet light resulting in the emission of visible light over an extended period of time

5. Fluorescence
The Immediate emission of visible light as a result of the absorption of ultraviolet light

6. Chemiluminescence
The direct production of light as the result of a chemical reaction with little or no heat produced

8. Biochemiluminescence
The production of light in living organisms as the result of a chemical reaction with little or no heat produced

9. Biochemiluminescence: Video

10. Triboluminescence
The production of light from friction as a result of scratching, crushing, or rubbing certain crystals

11. Light Emitting Diode (LED)
The production of light from an electronic device that allows an electric current to flow in only one direction.
