EL is manufactured using a printed process. This gives great flexibility - we can print to customise the product to your specific application.
EL is a phosphor based technology, and has a definite life cycle. In a typical application this would be a half life of approximately 3000 hours
The EL panel is driven by a AC source, typically 120VAC @ 400Hz. An inverter derives this from DC supply of 5-24VDC
The higher the frequency, the higher the light output. The lifetime is also inversely correlated to the frequency - increase the light intensity, reduce the life time.
It is common to integrate a light sensor or timer within the circuit to switch the panel on and off to maximise the effective life.
Phosphors are available in a number of different colours - blue-green often the most popular. White is also available.
EL Panels are very sensitive to humidity and moisture, and also to UV light. Special allowances have to be made if they are used in these environments.
