2-87: Broadband UV LED Radiometric Measurements Between 320 nm and 420 nm
Standard LED sources with different peak wavelengths (colours) and a standard broadband LED measurement procedure will be worked out to perform uniform, fast, and low-uncertainty radiometric LED measurements.

The standardized LED integrated radiance or the integrated irradiance from it and also the integrated responsivity of the reference radiometer can be determined. The reference scale will be propagated with the reference radiometer to field radiometers to perform one-step LED (broadband radiance or irradiance) measurements. The measurements can be applied for all kinds of LEDs and/or groups of different LEDs.

The purpose of this TC is to define an international standard for the optical measurements of semiconductor light sources (in particular LED packages and LED arrays as defined in CIE S 017-SP1) to the extent to which they emit incoherent optical radiation. Semiconductor light sources in terms of this standard are individual inorganic light emitting diodes or combinations of multiple objects of the same type in different two- or three-dimensional structures, which are distinguished and identified herein as LED packages and LED arrays. This document will not deal with e.g. LED lamps and luminaires as they are already covered by CIE S 025 or other applications of higher integration levels.
The standard shall describe in particular the geometrical arrangements, the electrical, thermal and temporal operating conditions and the measurement of the values of photometric, colorimetric and spectroradiometric quantities. Moreover, measurement quantities and associated measurement procedures are defined for describing the specific properties of LEDs and to take into account the restricted measurement options available during their manufacture or binning procedure.
The document does not cover semiconductor emitters for coherent optical radiation (lasers), nor limit values for evaluating radiation safety. The document does not cover measurements of bare LED dice (chip or wafer probing).

JTC 11 (CIE-ISO): Light and Lighting – Maintenance Factor – Way of Working
This deliverable will provide a standardized way of working for determining the maintenance factor for both indoor and outdoor installations using the methodology as described in CIE 154:2003 & CIE 97:2005.
The deliverable will combine insights from IEC standards w.r.t. product performance of luminaires and light sources currently in the market with the existing determination methodology from CIE technical reports. Furthermore, it will reference to the data in the CIE technical reports w.r.t. the impact of the environment on luminaires (accumulation of dirt on surfaces and luminaires).

JTC 12 (D1/D2/D8): The Measurement of Sparkle and Graininess
To provide a methodology to measure sparkle and graininess, and to develop a measurement scale. Measurands will be defined and the requirements for their measurements will be well normalized, in such a way that different instruments can provide the same spectrophotometric data from the same specimen. A psychophysical method will be recommended to obtain visual data, and its correlation with the spectrophotometric data will be worked out to develop the measurement scale for sparkle and graininess.

JTC 13 (D4/D3): Depreciation and Maintenance of Lighting Systems
To revise CIE 97:2005 and CIE 154:2003 in order to bring them up to date by incorporating recently used approaches for determination of lumen maintenance of LED lamps, dealing with lamp and ballast/driver survival factor and upgrading the luminaire maintenance factor according to current technologies and environmental factors. To deal additionally with distortion of luminous intensity distribution due to environmental influences. To extend the document by maintenance of LED luminaires regarding their cooling specific requirements.

JTC 14 (CIE-ISO): Integrative Lighting
To undertake an analysis of published scientific studies and review experience from published application studies on non-visual effects of light on humans, with the aim to provide guidance for safe and beneficial use in lighting applications beyond illumination for vision. The material to be analysed is existing material plus the outcome from studies that will become available during the period of this JTC. In particular, the work of the CIE on light as an input for all known photoreceptors in the human eye is included. The outcome of this JTC shall not cover subjects where no proper scientific validation is available and will concentrate on “low hanging fruit” or only provide the status of the different aspects of this topic.

JTC 15 (CIE-ISO): Lighting Of Indoor Workplaces
To revise ISO/CIE 8995-1 in response to its systematic review.

JTC 16 (D1/D8): Validity of Chromatic Adaptation
Recent experimental work revealed the incomplete chromatic adaptation under white light, especially those with low CCT and off-Planckian chromaticities, which are important to the performance of chromatic adaptation transforms. This was not considered in existing chromatic adaptation transforms (CATs). The TC will review the existing CATs and propose modifications by including a two-step transform to take the effect of white light chromaticity on degree of chromatic adaptation into consideration.

JTC 17 (D1/D2/D8): Gloss Measurement and Gloss Perception: A Framework for the Definition and Standardization of Visual Cues to Gloss
To describe recommendations for standardised visual assessment conditions of individual, established cues to gloss, to make reommendations for the definition of a standard gloss observer for individual diagnostic cues and, based on the findings from the above, to suggest optical methods and metrics for describing gloss in correlation with the established gloss cues.

JTC 18 (D3/D4): Lighting Education
The purpose of this JTC is to revise and update CIE 99:1989 and to provide recommendations on curricula for higher education and continuing education. To propose recommendations for education of lighting professionals and recommend options to improve and support continuing lighting education throughout the professional working life.
