If there's one thing common in the Electroluminescent world, it's that hearing the loud, audible noise coming from the inverter is well, annoying. Since Ellumiglow began, we've been scheming on how to minimize the noise that are common with EL Inverters.
Why do they make that noise anyway?
Luminescence is a phenomenon that occurs around the world, like bioluminescence, where particular organisms produce a chemical reaction where light is produced. In the world of Electroluminescence, we take an Electroluminescent phosphor, and apply a charge to it to create that luminescence. In this case, we apply an AC voltage and high frequency which is necessary to excite these phosphor particles and create light. Typically when applying the high frequency component, this actually ends up in our audible range, and comes across as a "buzzing" sound. Over the years, we've worked on mitigating this noise through various architectures, but making a completely silent inverter is nearly impossible.
