| 1.Principle of EL |
| |
|
| |
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. |

| 2.Structure of EL |
| |
|
| |
 |
The basic structure of EL consists of a transparent electrode layer on a flexible substrate,a phosphor layer,a dielectric layer,a back electrode layer,and a protective layer.A simplified structure of EL is shown in the figure. |

| 3.Features of EL |
| |
|
| |
EL lamps are flexible,thin,light,and cold illumination source that can be cut into any desired shape for lighting LCD displays,aircraft instrument panels, architectural accents,advertising signage,and special effects for theaters,studios and sports stadiums.
①Broad visual angel,plane solid light source,which no other lamps can compare with
②Super-thin and flat,they're thin as 0.2mm.
③Flexible and can be fabricated to any shape as you design.
④Strength in shock proof EL lamps are shockproof.
⑤Soft and stable
⑥Low power waste it can work with very low power consumption.
⑦No heat emitted
⑧Long lift cycle the lasting lighting time can be up to 25000hours. |
