Plasma Light Emitting Polymer

The new PLEP PLASMA Lighting

This superior lighting technology PLEP (Plasma Light Emitting Polymer) produces more than 123lum/w. This next generation of compact energy efficient lighting is circa 30% more efficient than LED. Available colour temperatures are 2250 to 6000k, degradation is 1% over 5 years.

What is PLEP?

In 1977, Alan J. Heeger, Alan MacDiarmid and Hideki Shirakawa found out that a thin film of polyacetylene could be oxidized with iodine vapors, turning the material into a conductor. This remarkable finding earned them the 2000 Nobel Prize in Chemistry.
When a low voltage is applied across the material it produces light. The challenge was converting this phenomena into a useable product for the lighting industry. PLEP lighting works using these electroluminescent materials.
Following years of research by a team of engineers from Mexico, Japan and Taiwan the PLEP module was developed into a useable lighting product.
