In structural principle the EL lamp is a kind of completely different backlight source as LED lighting, which is a full-plane light source with nearly 90% uniformity and no problem on any visual angle. EL lamp can show any color in single lighting color with customized design and control by its own inverter to present animated and flash performance.
Thin, Flexible, Vibration-resistant, resistant to flat pressure and no heat are EL features, even especially it has less restriction on the installation.


The full name of EL lamp is “Electro Luminescent Lamp”(EL). EL is an electrical phenomenon in which a material (phosphorus) emits light when electricity is passed through it. When EL is connected to AC power, a bias voltage field is generated, and electrons excited by the electric field collide with the luminescent particles to form an electric absorption state and then emit light. The light source is EL light.
