Material	Electroluminescent materials
	Electroluminescent materials produce a brillant light of different colours when stimulated electronically (e.g. by AC current). While emitting light no heat is produced. Like a capacitor the materials is made from an insulating substance with electrodes on each side. One of the electrodes is transparent and allows the light to pass. The insulating substance that emits the light can be made of zinc sulphide or a combinatio They can be used for making light stripes for decorating buildings, or for industrial and public vehicles safety precautions.

Environmen- tal notes	Use: Energy consumption is low since no heat is generated. Lifetimes are quite long and the material is robust.
