¢û. Materials & Equipments for EL
¢ñ.What is electro-luminescent (EL)
An electro-luminescent (EL) lamp is structured with a phosphor layer sandwiched between two electrodes; it functions electrically as a capacitor. When AC voltage is applied across the electrodes, the light generated from the phosphor is radiated through the transparent top electrode. EL lamps have extremely low power draw and generate no heat under normal operating conditions. EL lamps are flexible ¨C they can bend to conform to a products¡¯shape and even operate while being flexed.
EL lamps are virtually shock-proof and are not subject to catastrophic failure. They¡¯re thin ¨C as thin as 0.008 inches,allowing them to provide light while using minimum space. Their soft, even light is completely non-glaring. You can use EL lamps with virtually any display technology ¨C LCD,conductive rubber keypads, membrane switches, control and instrument panels, and more.

III. Products Characteristics
1. |
Cool light source: EL doesn¡¯t emit heat and thus avoids the problem caused by heat accumulation. |
2. |
Flexibility: EL sheet can be curled into any shape, which is very convenient for the products¡¯ design and development. |
3. |
Small volume: The EL sheet can be as thin as 0.2mm which is specially fit for the locations of strict requirement. |
4. |
Rich colors: With different formula, it can emit lights of different colors like blue, blue green, green, orange, white, |
|
purple, pink and red. |
5. |
Even luminance: Its luminance is even, soft and stable. It has good penetration through the frog. It doesn¡¯t cause any |
|
harmful ray. |
6. |
Pressure proof and anti-vibration: Different from other light source. EL won¡¯t be disabled or damaged because of punch or |
|
pressure from outside.7. Long-life: Its life can last over 10,000 hours in good condition. |
IV. EL¡¯s Applications
1. |
Backlight for LCD: applied to various computers, home appliance, clock, watch, telephone, Beep pager, electronic dictionary |
|
and remote controller etc. |
2. |
Meters: back light and light plate for meter and apparatus for automobile, motorcycle, plane, ships. |
3. |
Informational Signs: entrance and exit signs, road sings, floor signs, fire apparatus signs, warning signs, vehicle number |
|
plates and direction signs etc. |
4. |
Advertisement band: indoor colored, flashing band, badge and company¡¯s logo. |
5. |
Accouterments of gifts: decoration light for toys, badges, photo frames, gifts, Christmas¡¯ gifts, clothes, hats and shoes. |
V. Directions of usage
1. Form of enclosure:
Direct Contact: Contact point connects to PCB with zebra strip without contacting the electrode.
Pin Contact: Contact point connects to PCB with pins (FFC/FPC/metal pins).
2. Driver power:
The voltage and frequency for EL is not easy to obtain from batteries or alternative electricity network. It needs a transformer (inverter) to transfer the DV from the batteries or the AV into the right voltage and frequency. Through the EL driver¡¯s circuit, the EL products¡¯ flashing speed, times, cycle and colors can be controlled. Our engineers can design the best configuration according to your requirements and provide you¡¯re the right EL driver and IC.
