Model: HR-LA0028
An EL lamp consists of light emitting phosphor sandwiched between two conducting electrodes one of which is optically transparent allowing light to escape. As 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. Since the number of light pulses depends on the magnitude of applied voltage, the brightness of EL lamps can be controlled by varying the operating voltage and frequency.
