Solid-state light-emitting plastics
Light Beam Industries has developed a new solid-state light emitting plastic. The LEC (light emitting converter) material is based on patents by inventor Daniel Naum.
This new substance uses fluorescent laser dyes and solid-state light sources in conjunction with optical waveguides to generate multicoloured or white light.
The light is generated by wavelength shifting through a photoptic process of absorption and emission in the plastic material, which is a cross-linked polymer. The shorter wavelengths of light from the solid-state emitting source are absorbed completely - or partially, if preferred - and re-emitted as light at longer wavelengths.
LEC material has a wide range of potential applications, as well as offering the opportunity to save energy. Other uses include architectural lighting, instrument panels and switches, as well as, solid-state laser dye rods.
Future research and development will focus on nano-crystalline lasing structures incorporated in a plastic matrix (paint-on nano lasers) with further potential applications in lighting, solar collection and visual displays, as well as search and rescue.
