What are Electroluminescent Lamps?

Thin, flexible and light weight surface illumination, which can be tailored for complex shapes for a variety of backlighting and sign applications. EL lamps are impact and vibration resistant, require low power consumption, generate low heat in operation, and are manufactured using cost effective screen print process on wide stock. EL lighting is finding wide use for a variety of backlight applications in portable consumer electronics and telecommunications, for instrument illumination in the transportation industry, and for a variety of sign applications in the advertising and point of purchase industries.
? The EL lamp is essentially a capacitor structure with phosphor sandwiched between the electrodes. Application of an AC voltage generates a changing field within the phosphor which causes the phosphor to emit light.
? EL lamps are constructed using screen printable Polymer thick film compositions.
? A compatible system which is including phosphor, dielectric, Ag conductor, carbon conductor, translucent conductor and encapsulant compositions.

Advantages of EL Lamps

Electroluminescent(EL) Characteristics
1. Super-thin surface emission panel (as thin as 0.2 mm, low space needs, light
weight and pastable)
2. Solid cold light source (no heat generation, good tenacity, can be arbitrarily bent without affecting the light emission, can be freely processed)
3. Shockproof (Can stand high surface pressure and severe external shock)
4. Abundant emission colors (EL can emit four primary colors of light: blue, green,

blue-green, and white. Through dopant mixture and our unique manufacturing
technique, we can produce all kinds of colors you need.)
5. Low power consumption (lowest among the electrically-powered devices)
6. Long life-span (over 10,000 hours)
7. No harmful radiation (not harmful to eyes, soft light emission, no UV and other harmful radiation)
8. High visibility (high ability to penetrate through smoke and fog)
9. Arbitrary pattern design (can design true-color pattern and freely
10. good ability to stand humidity(can light in the water)
