Driven by the electricity(AC),the particle of luminescent material (ZnS)produces excitation jumping,and when returns to ground state,it is emitting high-frequency cold light.(Phosphor powder)

EL Structure
EL is the interlayer type structure, there are respectively two electrodes. The top electrode has the electric membrane, from which the light projects,and the bottom one is back electrode ,whose material is mainly silver or carbon. The luminescent material of EL is zinc sulfide (ZnS), when, it has different activators, and driven by the electric field, it can emit light of different colours. The brightness of EL varies with the interelectrode voltage, and frequency’ changing. Usually, when the voltage and frequency increase, the brigtness also increases correspondingly.

EL Features
·
Low power waste- emitting light even under low voltage,milliwatt level
·
Super-thin-(up to 0.2mm)
·
Curved- can be fabricated to any shape as you design,shining,and even can be folded
·
No heat emitted- Cold light source ,uncalefactive,the work temperature is lower than fluorescence
·
Soft and stable light-no coruscating,it won't hurt your eyes with tension,tiredness
·
Excellent shockproof- different from other luminophor, it won’t expire because of outside impact.
·
Long service life—EL life is weighed through half life ((half brightness), which is3000-20000 hour.
