4.3.2.2 The luminous intensity in any direction within the geometric visibility angle range shall not be greater than the maximum value specified in 4.3.1. 4.3.2.3 For rear parking lamps mixed with brake lamps, the luminous intensity in the area 5° downward from HH and below is allowed to be no more than 60cd. 4.3.2.4 In any direction within the geometric visibility angle range, the luminous intensity shall not be less than 0.05cd. 4.3.2.5 The luminous intensity within the range shown in Figure 1 shall be uniformly distributed, that is, the luminous intensity in any measurement direction within this range shall not be less than the minimum value of the specified test point in the grid where the measurement direction is located. 5 Test method
5.1 The test darkroom, devices and equipment shall comply with the provisions of GB4599. 5.2 Voltage or luminous flux during photometric test
5.2.1 For non-replaceable parking lamps, the voltage should be 13.5V or 28.0V. 5.2.2 For replaceable parking lamps, the corresponding standard bulbs should be used and the measurement should be carried out under the reference luminous flux specified in GB15766.1.
5.3 Before the photometric test, the bulb should be lit at the voltage used during the test so that its light performance tends to be stable. 5.4 The distance of the photometric test should ensure that the inverse square law of distance in photometry can be applied. 5.5 When observing from the reference center of the lamp, the test equipment should ensure that the detector angle is between 10' and 1°. 5.6 When measuring in any measurement direction in Figure 1, the angular deviation should not exceed 15'. 5.7 The measurement angle is measured based on the reference axis (determined by the manufacturer). 5.8 Photometric test for lamps with several light sources
5.8.1 For lamps with non-replaceable light sources or other light sources: If necessary, the manufacturer shall provide the special power supply required for such light sources and measure at the voltage specified by the manufacturer. 5.8.2 For lamps with replaceable light sources: When mass-produced bulbs are installed, at 13.5V or 28.0V, the luminous intensity shall be between the maximum value specified in this standard and the minimum value of the increase in the luminous flux deviation of this type of bulb specified in GB15766.1; or standard bulbs may be used in turn at each bulb position, measured at the specified reference luminous flux, and the measurement results at each position shall be accumulated.
5.9 Chromaticity inspection shall use standard light source A (color temperature is 2856K). For lamps with non-replaceable light sources, measurements shall be made at 13.5V or 28.0V.
