dim to dark conditions for momentary periods of

time. EL lamps typically consume less than LEDs

or bulbs making them ideal for battery powered

products. Also, EL lamps are able to evenly light

an area without creating "hot spots" in the display.

The amount of light emitted is a function of the

voltage applied to the lamp, the frequency at which

it is applied, the lamp material used and its size,

and lastly, the inductor used. There are many

variables which can be optimized for specific

applications. Sipex supplies characterization charts

to aid the designer in selecting the optimum circuit

configuration.
