Electroluminescent Lamps

Solid-state, light-emitting devices. Allows keyboards to be used in low ambient light conditions.

Electroluminence (EL) is the emission of light under electric-field excitation: the conversion of electrical energy into light energy in the form of photons.

In electrical terms, an EL lamp is a light emitting capacitor and is driven from an AC power supply.

Advantages over conventional back-lighting:

Effective, economical means of back-lighting
Low power consumption
Low heat and infra-red emissions
Flexible
Uniform light source
Ultra-thin
High Life
Low tooling cost
Range of colours
