New Technology - Overview

LumiFlux's new, patented technology makes our electroluminescent (EL) lamps distinctly brighter and more efficient than conventional EL lamps.

By comparing LumiFlux EL lamps to conventional EL lamps, you can clearly see the advantages of the LumiFlux technology:

• Capacitance increase: 42%
• Brightness increase: 100-200%
• Efficiency increase: 58%
• Current increase: 61%
• Power increase: 21%

Our new electroluminescent (EL) technology is in the field of alternating current driven, thick film, inorganic electroluminescence (ACTFEL).

The heart of all EL lamps is the light-emitting layer, formed by EL phosphor particles, dispersed in a dielectric media.

When alternating current is connected to the electrodes, the layer is functioning as a light-emitting capacitor. The capacitor will charge up/discharge repeatedly, as the polarity changes. An alternating electric field is created across the layer itself, energising the EL phosphor particles to emit light via electroluminescence.

The intensity of emitted light (brightness of the EL lamp) depends on the amount of energy stored in the capacitor and transferred to the phosphor particles.

For conventional EL lamps the capacitance of the light-emitting layer is set and limited by the principles of the parallel plate capacitor, due to the fixed area and thickness. In the LumiFlux EL lamp construction the novel light-emitting layer structure increases the capacitance by enlarging the surface area on both sides of the light-emitting layer. This change markedly increases the brightness, as the electric field is stronger and more energy is available to excite the phosphor at any given voltage. An additional advantage of the curved structure is that the energy transmission through the light-emitting layer is significantly improved. The electric field becomes concentrated across the individual phosphor particles and the field direction is aligned to the surface contour of the phosphor particle, causing an even stronger and more efficient excitation.
