TC 2-80 Spectroradiometric measurement of light sources
To specify current procedures for the spectroradiometry of continuous, line and mixed sources of optical radiation. Such procedures apply to measurements of irradiance, radiance and radiant flux in the near ultraviolet, visible and near infrared regions of the spectrum.
TC 2-78 The Goniophotometry of Lamps and Luminaires
To update CIE 121-1996, CIE 070-1987 and the relevant parts of CIE 084-1989 and combine these into the one technical report, incorporating new techniques and the absolute goniophotometry of lamps in their own right.
TC 2-76 Characterization of AC-driven LED Products for SSL Applications
To prepare a technical report on the measurement of characteristic quantities of AC driven LED products, including operational conditions, and photometric quantities focused on those influenced by the effect of flicker.
TC 2-72 The Evaluation of Uncertainties in Measurement of the Optical Properties of Solid State Lighting Devices, including coloured LEDs
To expand the supplements to CIE 198-2011 to include further principles and examples for evaluation of the uncertainties associated with the measurement and testing of LEDs and other solid state lighting devices. Examples include distribution photometry, spectral measurement and derived quantities, goniospectroradiometry and other priority measurements as advised by industry.
TC 2-70 Standards for Measurement of Reflectance and Transmittance Properties of Materials
To draft three new CIE standards that describe the minimum requirements for any instrument intended to measure the optical properties of planar, uniform, homogeneous (or nearly so) materials, The standards will define the geometric and spectral requirements, the processes for calibration or standardization of the scales and the required level of uncertainty for the measurement of spectral diffuse reflectance and reflectance factor, spectral regular transmittance and spectral diffuse transmittance, and spectral regular reflectance.
TC 2-67: Photometry of lighting and light-signalling devices for road vehicles
To prepare guidelines for the measurement of photometric performance of lighting and light-signalling devices for road vehicles Note: This technical committee is related to GTB Working Group Photometry. The TC will start their work based on an existing internal GTB Working Group Photometry Guide (GTB identification: CE-3874) and will incorporate the rules for the determination and the statement of measurement uncertainties as defined in the ISO publication "Guide to the Expression of Uncertainty in Measurement" ISBN 92-67-1018-9 (1995).
To prepare a technical report on high speed testing methods for electrical, thermal and optical quantities during the production of LEDs and the conversion of the values to DC operational conditions including the related time dependent functions.
To prepare a CIE recommendation on the methods for characterisation and calibration of imaging-photometry- based near-field goniophotometers and for determination and conversion of photometric data of lamps and luminaries for both near-field and far-field applications.
TC 2-60: Effect of Instrumental Bandpass Function and Measurement Interval on Spectral Quantities
To prepare a Technical Report that describes the effect of instrumental bandpass functions and measurement wavelength interval on spectrally resolved quantities and to provide recommendations on suitable methods to minimise the error introduced by instrumental bandpass functions on spectrally integrated or weighted quantities.
TC 2-51: The Calibration of Multi-Channel Spectrometers
To produce a technical report for the calibration of detectorarray spectroradiometers primarily for the determination of colorimetric and photometric quantities, including performance characteristics, calibration methods and guidance in the applications of methods for the determination of uncertainty.
Prepare a CIE guide on methods for the characterization of the linearity of detectors of optical radiation, including different principles by which the linearity of detectors can be determined and causes of non-linear behaviour, to aid users of optical radiation detectors in the selection and use suitable devices for specific applications.
