EL (electro luminescence) by adding at the poles have AC voltage AC field, the electric field excited by electron impact fluorescent substance (zns), electronic energy levels caused by the jump, change, launching a high-efficiency compound and a physical view of cold Like, that is, the phenomenon of electrical excitation. EL sheet (EL Lamps) is the use of this principle, and made by a special process with extensive use of advanced electroluminescent sheet.
The use of EL sheet
Electroluminescent film using a wide range, with the EL film manufacturing process improvements decreased the cost of production is widely used in various industries:
Main purposes:
LCD backlight
Clocks and watches
Toys, electronic products
Art of advertising signs
Emergency signs
Signs, car license plate
Instruments, meters, dial
Night Light
EL characteristics of film
> Ultra-thin smooth (0.12 ~ 0.4mm), light weight
> may be emitting surface can be made into any shape
> LED color semi-rich, complex color flashing can be made
> even and soft light
> does not produce heat, does not contain UV
> luminescence efficiency, low power consumption
> long life (> 25000Hr)
> Anti-vibration, no maintenance
EL and LED, CCFL performance comparison:
Brightness uniformity of light form of the cost for power-power applications
LED light source 80Cd/m2 no good sizes low
EL extremely small area light source 50Cd/m2 are small and medium sized high
CCFL line source> 100Cd/m2 have a good large large size and high
