Diffusers get better at handling LEDs

In addition to eliminating obvious light source points, light diffusion materials can be used to tint the color of the transmitted light. LEDs commonly go into numerous applications such as displays, exit signs, automotive lighting and ambient lighting in which color options are advantageous. Use of the diffusion technology gives product designers a broad palette of colors to customize applications.

Experts at the Bayer MaterialScience Color Competence Center can put colorants into the diffuser package so transmitted light appears as different colors. It is advantageous to incorporate the color into the plastic resin which is then molded, rather than use a traditional post-mold painting process. The molded-in color will not chip or scratch off, and the process itself is more efficient and economical than secondary operations.

One application where such innovation can help set progressive OEMs apart from the competition is automotive interiors. LEDs can provide a tailored design that is distinctive while consuming less energy. The finishing touches of a stylish and luxurious cockpit include an illuminated odometer and HVAC and radio dials, made possible via customized diffusion.
