Foreword
Clauses 4, 5 and 6 of this Standard are mandatory and the rest are recommended. This Standard is drafted in accordance with the rules given in GB/T 1.1-2009. The technical contents of the Class A headlamps in this Standard replace GB 19152- 2003; the technical contents of Class B headlamps replace the relevant specifications on the use of S1, S2 lamps or similar closed headlamps in GB 5948-1998; and compared with the former version, the main changes are as follows.
- ADD the type of light sources allowed to be installed, that is, add the filament lamp, gas-discharge light source or LED module light source;
- Relative to the added type of light source, add the photometric characteristic requirements for a number of new classes of headlamps;
- ADD the photometric characteristic test method for semi-enclosed headlamps with adjustable reflectors;
- ADD the relevant contents of corner illumination;
- MODIFY the test voltage from 12 V to 13.2 V;
- MODIFY the measurement coordinate system from flat system to spherical system, and modify the measurement unit from lux to candela;
- ADD Annex A ?€?Voltage markings?€?;

3 Terms and definitions
For the purpose of this document, the following terms and definitions and those defined in GB 4599, GB 4785 and GB 25991 and apply.
3.1
complete headlamp
The entire lamp, including the lamp body parts around the lamp body that may affect the heat dissipation, and electronic light source controllers.
3.2
additional lighting unit
A headlamp system that provides corner illumination, independent of devices providing basic passing beam, may consist of optical, mechanical and electrical components, and may be combined and/or grouped with other lighting or optical signaling devices. 4 Class and different types of headlamps
4.1 Headlamps of different classes
Headlamps of different classes (Classes A, B, C, D or E) are headlamps that comply with particular photometric provisions.
4.2 Headlamps of different types
Headlamps which differ in the following aspects.
- The trade name or mark;
- The characteristics of the optical system;
- The inclusion or elimination of components capable of altering the optical effects by reflection, refraction, absorption and/or deformation during operation; - The kind of beam produced (passing beam, driving beam or both);
- The category and parameter (such as voltage, power, luminous flux, chromaticity, color rendering, etc.) of filament lamp(s), the gas-discharge light source or the light source/module;
c d and the luminous intensity at 0.86DV be not less than 2400 cd;
c) In addition to the additional light sources/additional lighting units that provides the corner illumination, it will obtain either passing beam or driving beam, and will not stop between the two positions;
d) Using the usual tools, the user cannot change the shape and position of moving parts.
5.1.4 The lamp body of the headlamp shall indicate the type of the filament lamp and/or the gas-discharge light source used; the headlamps with LED modules shall be marked with the rated voltage and the rated power on the lamp body; Class E headlamps shall be marked with the voltage marking shown in Annex A; the reference center mark indicated in Annex B may be marked on the photometric lens. If additional lighting units are used, the headlamps emitting basic passing beam shall be marked with the type of filament lamp used and/or the rated voltage and rated power of the LED modules used for additional lighting units.
5.2 Headlamp?€?s light color
The light color of the headlamp shall be white, and its chromaticity characteristics shall meet the requirements of GB 4785.
5.3 Headlamp?€?s light source
