Cnam Lounched Research Project on Characterization of Colour Rendering of LED Light Sources
The CIE method applied since 1974 for defining the CRI (colour rendering index) allows the quantification of the "quality" of the light generated by artificial light sources. This index ranging from 0 to 100 defines the capacity of a light source to reproduce the various colours of objects, compared to a reference source, but does not apply correctly to LEDs. So, new studies are recommended to determine a new colour index or indices which take white light produced by LEDs into account.

Researchers Believe that New Technology Could Replace the Household Light-bulb Within Three Years
Light Emitting Diodes (LEDs), already used in electrical equipment such as computers and mobile phones, are several times more energy efficient than standard light-bulbs. However, because of their structure and material, much of the light in standard LEDs becomes trapped, reducing the brightness of the light and making them unsuitable as the main lighting source in the home.

Hybrid Semiconductors Show Zero Thermal Expansion
Thermal expansion can separate semiconducting materials from the substrate, reduce performance through changes in the electronic structure of the material or warp the delicate structures that emit laser light. Recently published research by scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and Argonne National Laboratory, and academic institutions has shed light on a semiconducting material with zero thermal expansion (ZTE).
