CIE DIS 026/E
Abstract: This International Standard defines spectral sensitivity functions, quantities and metrics to describe radiation for its ability to stimulate each of the five photoreceptor types that can contribute, via the melanopsin-containing ... -
CIE 222
Abstract: Within this document, energy efficiency, user acceptance and lighting quality are evaluated on a qualitative scale from ‘none’ to ‘very high’. The document will not result in a calculation method ... -

CIE 228
Abstract: Introduction This report presents the calculation of a self-luminous neutral scale as a complement to the original use of CIE lightness, L*, as defined in the CIELAB and CIELUV colour spaces ( ISO/CIE, 2008; ISO/CIE, 2016), ... -
CIE 223
Abstract: Background Increasingly, colour imaging is being done with cameras capable of capturing more than three channels or bands. With its focus on promoting colour science, CIE Division 8 "Image Technology" established a technical ... -
CIE 229
Abstract: Introduction Flashing lights are widely used in many signalling applications in aviation, marine and land transportation. Flashing lights, such as aircraft anti-collision lights, marine aid-to-navigation lights, obstruction ... -
CIE 227
Abstract: Introduction Recently, energy conservation has become a global concern. Lighting is often the first thing to be turned off when electrical energy has to be conserved. For instance, after the Great East Japan Earthquake hit ... -
CIE 226
Abstract: Introduction This report and the Technical Report CIE 225:2017 on optical measurement of high-power light emitting diodes (HP-LEDs, see 3.3) (CIE 2017) are intended to extend the scope of the technical report CIE 127:2007 ... -
CIE 150
Abstract: This Guide is an update of Publication 150:2003 which sets out guidelines for assessing the environmental impacts of outdoor lighting and gives recommended limits for relevant lighting parameters to contain the obtrusive ... -
CIE 225
Abstract: This technical report deals with methods used by calibration and testing laboratories for the measurement of optical quantities (including photometric, radiometric, and colorimetric quantities) of HP-LEDs, with focus on ... -
CIE 224
Abstract: Summary 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 ... -

CIE 218
Abstract: Scope: Introduction Evidence that a separate photoreceptor detects irradiance and provides the entrainment signal for circadian regulation (Berson et al. 2002; Hattar et al. 2002) has galvanized lighting researchers, ... -

CIE 220
Abstract: Scope: The UV radiometers considered in this document are restricted to those designed for the wavelength range from 200 nm to 400 nm, i.e. in the spectral bands of UV-A (315 nm to 400 nm), UV-B (280 nm to 315 nm) and part ... -

CIE 217
Abstract: Scope: Introduction For a pair of colour samples, the magnitude of the visually-perceived colour difference between such samples, usually designated as ΔV, can be considered as much as the computed colour difference ... -
CIE 222
Abstract: Scope: Within this document, energy efficiency, user acceptance and lighting quality are evaluated on a qualitative scale from ‘none’ to ‘very high’. The document will not result in a calculation ...
