EL lamps are essentially a flat capacitor structure with microencapsulated zinc sulfide phosphor particles sandwiched between two electrodes. One of the electrodes is transparent to allow light to escape. Application of an AC voltage across the electrodes generates a changing electric field within the phosphor layer. This change of field causes the phosphor particles to emit visible light.
EL lamps draw very little power, and produce little heat. Because they don't contain filaments or mechanical parts, EL lamps are not susceptible to shock, vibration or catastrophic light failure, making them ideal for applications such as cellular phones, hand-held portable electronic devices, and automotive backlighting and “mood” lighting.
GSI is a recognized leader in EL production, testing, and qualification. GSI’s EL lamps are among the brightest available. We can design EL lamps for any size, shape, or form you can imagine. All that’s needed is a low electrical current to make the millions of tiny phosphor particles in the lamp glow.
