FAQs :
1, Why LEDs?
The term LED stands for Light Emitting Diode, which are tiny light bulbs that fit easily into an electrical circuit. But LEDs last much longer than incandescent bulbs because they do not have a filament that will burn out, and the LEDs are always cool to the touch. They are illuminated solely by the movement of electrons in a semiconductor material. A semiconductor is something that will conduct electricity. This semiconductor material is referred to as Solid State Lighting. In a solid state, the LEDs resist vibration and are much more durable than traditional forms of lighting. LEDs use these Light emitting diodes instead of electrical filaments (incandescent) or the gas and mercury used in the compact fluorescent's (CFL's).
Benefits of LED lighting:
High efficiency, up to 80% more efficient than Halogen lights and 50% better than fluorescent, providing you with enormous cost savings.
Customizable Lighting, LEDs are directional, no more wasted light where it is not necessary, 30° 60° 90° or 120° light spread
Colors Available: Warm white (3000K)
Daylight (4500K)
Cool white (6000K)
Red, Green, Blue, Amber & selected custom colors
Most products available in multiple voltages upon request
Additional Benefits
· Safer, no burns when light is touched
· Simple to install (direct replacement for incandescent, CFL & Halogen)
· No RF wavelengths emitted to interfere with radio frequency
· Lights instantly (no warm up period like CFLs)
· Silent operation
· Won't cause migraines like CFLs
· Produce enhanced lighting colors conducive to alertness
· UV free - Won't attract bugs in outdoor applications
· Earth Friendly, keeps waste to a minimum in landfills
What is EL?
EL: Electroluminescent, through DC electric field result from both positive & negative voltage, bump ZNS on electronic stimulated by electric field, the change with active & positive feedback, composition of electrode which result in a physical phenomenon with high efficiency cold lighting, it is called electric lighting phenomenon. El is an advanced and worldwide lighting while using aforesaid principle.

EL Applications:
· LCD backlights
Since EL has even brightness, super-thin, low power consumption, EL lighting is the most appropriate light source for LCD backlights. lt results in unestimated
development of EL products. Currently our company has explored and applied EL to instrument/apparatus, acoustic, BP, mobile phone, portable computer, telephone, calculator, clothes, cap and so on.
