Show transcript
Incandescent means emitting light due to high temperature.
Incandescent light bulbs use more energy than LEDs.
LEDs are more energy efficient due to the movement of particles directly creating light without high temperatures.
Electroluminescent materials are used in LEDs, these compounds can be changed to create different coloured LEDs.
LEDs can be used individually or grouped together in a matrix to display images or words.
