Automotive lighting devices according to the requirements of the UNECE Regulations (112, 128, 98, 48, 19, 7, etc.)

Description

This program for measuring the characteristics of light devices installed on automobiles, trailers, motorcycles, etc. according to the requirements of the Uniform Regulations (UNECE Regulations) involves a full range of studies of lighting products (photometric, colorimetric and electrical parameters) with the conclusion that the measured parameters correspond to the specified in the indicated documents. The particular relevance of the proposed program is the possibility of implementing all the measurement techniques contained in the documents by the measuring complex of the ARCHILAYT laboratory. Thus, for example, Revision 3 of UNECE Prescriptions 112 (January 2013) contains the lighting requirements for the parameters of headlamps, expressed in units of luminous intensity (cd), while the previous Revision 2, as well as GOST R 41.112-2005 similar requirements treats in terms of surface illumination (lx) from headlights. This means that these circumstances make it impossible to comply with the international requirements of the UNECE Regulations for products whose certification tests were carried out within the framework of the Russian standard GOST R 41.112-2005. Similar requirements are also found in Rules 128, which contain requirements and methods for measuring light sources, including LED ones, used in automotive lighting devices.

The proposed program for studying the characteristics of automotive lighting devices involves measuring such complex elements as the cut-off parameters of headlights, the spatial distribution of colorimetric characteristics and the luminous intensity of optical elements of headlamps, and the localization of the luminous flux direction of light sources (UNECE Regulations No. 120, 128). Much attention is paid to the measurement of the parameters of such critical elements as braking signals, additional braking signals (DST), signals of direction indicators and running lights.

The proposed program is based on the high metrological characteristics of the measuring equipment of the ARCHILITE laboratory (Spekord spectrometric installation (State Register of SI No.39537-08), Flax goniophotometric installations (State Register of SI No. 39536-08 and No. 39535-08) (Patent No. 130394)) which underlie the measurement techniques adapted to it, as contained in the UNECE Prescriptions.
