GB 4599 Motor Vehicle Headlamps Equipped with Filament Lamps GB 4785 Prescription for Installation of the External Lighting and Light-Signalling Devices for Motor Vehicles and Their Trailers3 Terms and DefinitionsFor the purpose of this Standard, the terms and definitions given in GB 4785 apply.4 Classification4.1 Categories of direction indicators The categories and minimum angles of light distribution of devices are specified in accordance with their installation positions and functions on the vehicle (See Figure 1). 4.2 In Figure 1, the vertical angle V corresponds to the horizontal plane, with the positive above the horizontal plane and the negative below the horizontal plane; 5 Direction Indicators of Different Types Lamps which differ in such essential respects as.6 Specifications6.1 The devices shall be so designed and constructed that under normal conditions of use and notwithstanding the vibrations to which they may be subjected in such use, their satisfactory operation remains assured and they retain the characteristics prescribed by this Standard. 6.3 The devices equipped with replaceable light sources shall be equipped with filament lamps meeting the specifications of GB 15766.1 or ECE R37. 6.4 The light source modules used shall be so designed that even if in the dark, they can be installed at the correct positions; and that they can prevent maloperation. 6.5 Photometric performance 6.5.1 See Figure 2 for the requirements for light distribution. The numbers at the intersections of grid lines in Figure 2 indicate the minimum values of luminous intensity in the direction and the reference axis direction [categories 1, 1a, 1b, 2a, 2b, 3 and 4 (forward)] or the ratios of the minimum values of luminous intensity of direction A (category 6), direction A meaning the direction H = 5° and V = 0°. 6.5.3 Within the luminous intensity distribution field (see Figure 2), except in the reference axis direction and A direction. 6.5.4 The requirements for all categories of devices within the minimum angle of light distribution (See Figure 1). 6.5.4.1 The intensity of the light emitted shall be. 6.5.4.2 Outside of the field 10° (i.e. H = ± 10°, V = ± 10°), the luminous intensity of devices of categories 1, 2b (by night), 3 (forward) and 4 (forward) shall not be more than the limits of Table 2; in the zone (including boundary) between field 10° and field 5° (i.e. H = ± 5°, V = ± 5°), the allowable maximum luminous intensity of these devices shall also increase gently to the maximum values specified in Table 1. 6.6 In the case of devices of category 2b the time that elapses between energizing the light source(s) and the light output measured on the reference axis to reach 90 per cent of the initial values measured when the light sources give out a continuous light shall be measured while they are operated by day and by night. The corresponding time by night shall not be more than the time by day. 6.7 When a mounting height is less than 750 mm above the ground, the photometric intensity is verified only up to an angle of 5° downwards.7 Test Procedure7.1 The test darkroom, apparatus and equipment shall meet the specifications of GB 4599. 7.2 The limits of the apparent surface in the direction of the reference axis of a direction indicator shall be determined. 7.3 Photometric test voltage 7.4 Before photometric performance measurement, the light source shall be lit at the voltage of measurement, to make its photometric performance become stable. 7.5 However, depending on the construction of the device, for example, the use of light-emitting diodes (LED), or the need to take precautions to avoid overheating, it is allowed to measure the lamps in flashing mode. 7.5.1 This shall be achieved by switching with a frequency of f = 1.5 ± 0.5 Hz with the pulse width greater than 0.3 s, measured at 95 per cent peak light intensity. 7.6 Photometric performance measurement of all categories of devices. 7.6.1 For lamps equipped with non-replaceable light sources, the photometric characteristics should be verified with the light sources present in the lamp. 7.7 During photometric measurements, stray reflections shall be avoided by appropriate masking. 7.8 The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable. 7.9 The measuring equipment shall be such that the angular aperture of the receiver viewed from the reference centre of the light is comprised between 10' and 1 degree. 7.10 The intensity requirement for a particular direction of measurement in Figure 1 shall be deemed to be satisfied if that requirement is met in a direction deviating by not more than one-quarter of a degree from the direction of measurement.8 Inspection Rules8.1 Devices of different categories shall be determined according to the specifications of Chapter 5. 8.2 Devices shall be tested by type approval test and conformity of production test. When they meet the specifications of 8.3 or 8.4, it shall be deemed that they have passed type approval test or conformity of production test. 8.3 Type approval test 8.4 Conformity of production procedures 8.4.1 For the devices qualified by type approval test, use the sample lamps taken at random from the products mass-produced to determine their conformity of production. 8.4.2 The sample lamps taken at random shall meet the specifications of 6.1, 6.3 or 6.4 and 6.6. 8.4.3 The sample lamps taken at random shall meet the specifications of 6.2 when they are tested according to the specifications of Chapter 7. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
