What is EL (Electroluminescence ) product?
The typical EL products are consisted of light emitting phosphor sandwiched between two conductive electrodes. When an AC voltage is applied to the electrodes, the electric field causes the phosphor to rapidly charge and discharge, resulting in the emission of light during each cycle. The number of light pulses is determined by the magnitude of applied voltage, so the brightness and color of EL products will vary subject to the change of the operating voltage and frequency......... |
