1 Scope
This document specifies the same type determination, overall requirements, light source
requirements, light color requirements, photometric performance, photometric stability,
test methods and inspection rules for road illumination devices and systems for motor
vehicles.
This document applies to the design, manufacture and acceptance of road illumination
devices and systems such as passing beam, driving beam, front fog lamps, corner lamps,
etc. used in M and N category vehicles.
2 Normative references
The following documents are referred to in the text in such a way that some or all of
their content constitutes requirements of this document. For dated references, only the
version corresponding to that date is applicable to this document; for undated references,
the latest version (including all amendments) is applicable to this document.
GB 4785, Prescription for installation of the external lighting and light-signalling
devices for motor vehicles and their trailers
GB/T 43081-2023, Lamps and light sources for road vehicles - Dimensional,
electrical and luminous requirements
IEC 60825-1.2014, Safety of laser products - Part 1.Equipment classification and
requirements
3 Terms and definitions
For the purpose of this document, the following terms and definitions, as well as those
given in GB 4785, apply.
3.1
road illumination device
A unit or group of units used to illuminate the road and objects in the direction of the
vehicle's advance to achieve one or more functions.
3.2
road illumination system
A system – consisting of left and right side units or unit groups and a controller – used
to illuminate the road and objects in the direction of the vehicle's advance.
3.3
lighting unit
The light-emitting component of the system, which provides a light beam for one or
more road lighting functions of the system.
3.4
installation unit
An inseparable housing (lamp body) containing one or more lighting units.
3.5
neutral status
The system is in use without any adaptive control signal input.
4 Determination of identical types
Devices that do not differ in the following main features are considered to be of the
same type.
5 General requirements
5.1 Beam adjustment device
5.2 Beam switching device
The device used to switch the light beam in the device or system shall meet the
following requirements.
5.3 Marking of device or system
5.3.1 The lamp body of the device or system shall be marked with the rated voltage.
Devices or systems that are applicable only to 12 V rated voltage systems or only to 24
V rated voltage systems shall comply with the provisions on voltage marking in
Appendix A.
5.4 Reference center marking
The device or system shall be marked with the reference centre, and the marking
method shall comply with the provisions of Appendix A. If two driving beam
headlamps are installed on each side of the vehicle, each driving beam headlamp shall
be marked separately.
5.5 Driver assistance projection function requirements
6 Light source requirements
6.1 Replaceable light source
6.2 Non-replaceable light source
6.2.1 For light sources that can only be replaced as a whole with the device or
installation unit, filament light sources or gas discharge light sources shall not be used.
This requirement does not apply to corner lights.
6.2.2 Headlamps may use LED modules or laser light source modules. If laser light
source modules are used, the passing beam and driving beam shall comply with the
requirements of 4.4 of IEC 60825-1.2014 and the requirements of BLH-C of IEC
62471-7.2023.Laser modules are not allowed to be used in front fog lamps and corner
lamps.
6.2.3 The LED modules or laser light source modules used in the device or system shall
be able to prevent misoperation and their design shall comply with.
7 Light color requirements
The light color of the device and system shall be white, and the light color of the front
fog lamp can also be selectively yellow. The chromaticity characteristics shall comply
with the relevant provisions of GB 4785.
8 Light distribution performance
8.1 General requirements
All light distribution performance tests required by this document shall be carried out
in the coordinate system specified in Appendix B.
8.2 Passing beam distribution performance
8.2.3 If the passing beam has an adaptive function, it shall comply with the provisions
of Part A of Table 1 under the conditions of use specified by the applicant or
manufacturer. Under the adaptive function state of the passing beam, when the driving
speed is greater than 70 km/h, if it cannot meet the provisions of Part A of Table 1, its
light distribution performance shall comply with the provisions of Part A of Table 2.
8.2.5 For the S50, S50LL, S50RR, S100, S100LL and S100RR test points, the front
position lamps may be turned on during the test.
8.2.6 When using the passing beam adaptive function, it shall be possible to manually
switch to the basic passing beam at any time. Manual switching is allowed between
different adaptive systems. The beams within the same adaptive system shall be able to
switch automatically. The same adaptive system shall include a basic passing beam
mode.
8.5 Corner lamp light distribution performance
8.5.1 The test points of light intensity are expressed as angles relative to the datum axis.
The coordinates and diagrams of all the following test points correspond to the device
installed on the left side of the vehicle. For the device installed on the right side of the
vehicle, the coordinates of the test points in the left and right directions need to be
mirrored.
9 Light distribution stability of devices or systems (except corner lamps)
9.1 General
According to the requirements of Appendix E, test the clean lamp, dirty lamp and
changes in the vertical position of the cut-off line under the influence of heat. The test
results shall meet the requirements of 9.2 ~ 9.4.
9.2 Clean lamp light distribution performance stability
9.2.1 Once the sample has stabilized to ambient temperature, a clean damp cotton cloth
shall be used to clean its lens. Visual inspection shall be carried out to find no obvious
deformation, distortion, cracks or discoloration of the lens.
9.3 Dirty lamp light distribution performance stability
After the dirty lamp test is carried out according to E.2.2 in Appendix E, the test results
shall meet the requirements of 9.2.
9.4 Changes in the vertical position of the cut-off line under the influence of heat
9.4.3 Calculate the average value of the two tests Δr' = (ΔrⅠ +ΔrⅡ)/2.If Δr' does not
exceed the limit given in Table 12, it is considered to meet the requirements.
10 Devices or systems equipped with LED modules or laser light source modules (except corner lamps)
10.1 General requirements
10.2 UV (ultraviolet) components
UV component KUV of the light emitted by the low-UV LED module or laser light
source module shall be calculated according to Formula (1), and KUV shall not be
greater than 10-5 W/lm.
