ELECTROLUMINESCENT LIGHTING
EL is manufactured using a printing process. This gives great flexibility – we can print to customize 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 an AC source, typically 120AV at 400Hz. An inverter derive 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 lifetime. It is common to integrate a light sensor or timer within the circuit to switch the panel on and off to maximize 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
