Click here to purchase The CIE Colour Rendering Index (CRI), defined in CIE 13.3-1995, in particular the general colour rendering index, Ra, is widely adopted and used by the lighting industry, in regulatory documents and in international and regional standards and specifications. However, limitations of the CRI have been recently addressed, especially for solid-state light sources, whereby the...

Click here to purchase This new edition of the International Lighting Vocabulary (ILV) is the result of intensive work carried out by the Divisions of the CIE to update, and supplement where necessary, the contents of the previous edition (1987). Many new terms have been added, to reflect changes in technologies and practices, existing terms have been updated as necessary, and obsolete terms have...

Click here to purchase TThis standard provides requirements to perform reproducible photometric and colorimetric measurements on LED lamps, LED modules, and LED luminaires (LED devices). It also provides advice for the reporting of the data. The availability of reliable and accurate photometric data for LED devices is a basic requirement for designing good lighting systems and evaluating...

Click here to purchase LED light sources are now widely used in illuminating engineering as well as in information technology and are expected to be one of the major light sources in our future life. Despite the wide and rapidly growing use of LEDs, reliable methods for physical light measurement and visual and photobiological evaluation are still in question. The CIE had organized two successful...

Click here to purchase This symposium provides an outstanding example of true interdisciplinary collaboration among the worlds of medicine, biology, physiology, psychology and the world of "lighting practice".An exciting new discovery, two years ago, of a new photoreceptor in the eye - in addition to the rods used for night-vision and the cones used for colour-vision - was described in some...
