Electroluminescent lamps driver on compatible flexible substrates

The electroluminescent lamps became more and more used in automotive industry and also in advertising industry domain or as backlight for LCD's. An electroluminescent lamp is basically a capacitor that contains a phosphor layer located between conductive layers that form the plates. With increasing field strength the phosphor absorbs energy and produces light. One of the capacitor electrodes is transparent and this way it is possible to use the structure as a light source. In most cases there are more lamp structures, manufactured together and presented as electroluminescent foils. The scope of the paper is to design a power supply capable to provide power to these foils under different conditions and under different environment factors. In this sense, measurement of electrical characteristics of these foils will be made. The influence of electrical parameters on light emission will be investigated.
