Lighting and light signal devices; --- Part 2. Retroreflective device; --- Part 3. Installation and use of illumination and retroreflective devices; --- Part 4. Bicycle lighting power supply lighting system; --- Part 5. Bicycles turn the lighting system that is not powered. This part is the first part of GB/T 31887. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 22791-2008 "Bicycle Lighting Equipment", compared with GB/T 22791-2008, the main technical changes as follows. --- Modified the standard name; --- Revised the scope of the content (see Chapter 1, Chapter 1 of the.2008 edition); --- Revised the normative reference document (see Chapter 2, Chapter 2 of the.2008 edition); --- Added "front position light", "brake light", "low beam", "high beam", "turning light", "parking light", "light with replaceable light source" The term "and HH plane", "VV plane", "public road", "short pulse" and "electric bicycle" with non-replaceable light source Meaning (see 3.1, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.13, 3.14, 3.15, 3.16, 3.17); ---Delete "two-wheeled bicycle", "filament light", "reference center", "beam center", "rated voltage", "test piece", "standard luminous flux", "system" Terms and definitions (see.2008, 3.2, 3.5, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12); --- Increased the "General Principles" for photometric requirements (see 4.1); --- Increased the "photometric requirements" of the front position lights (see 4.2); ---Modified the "photometric requirements" of the backlight (see 4.3.1.1, 5.1.1 of the.2008 edition); --- Increased the "lighting method" of the backlight (see 4.3.2); --- Removed the brightness value of the headlights, test pieces (see 4.1.1, 4.1.2 of the.2008 version); --- Increased the luminosity requirements and lighting methods of "brake lights", "low beam", "high beam", "turning light" and "parking light" (see 4.4, 4.5, 4.6, 4.7, 4.8); --- Modified the chromaticity coordinate values (see Chapter 5,.2008 edition 4.2); --- Modified the test method (see 6.1,.2008 version 4.1.3, 5.1.3); --- Added "power and light source for testing optical performance" and "test bench installation" (see 6.2, 6.3); --- Removed "Motor Motor" "Battery" "Switch Performance" "Environmental Test" "Mark" "Instructions" (see Chapter 6 of the.2008 edition, section Chapter 7, Chapter 8, Chapter 9, Chapter 10, Chapter 11); --- Added appendix "Flash Measurement" "Light Color" (see Appendix A, Appendix B); --- Removed the appendix "various typical filament lamps" and "vibration testing machine" (see Appendix A, Appendix B of the.2008 edition); --- Added references. This section uses the redrafting method to modify the use of ISO 6742-1.2015 "Bicycle lighting and retroreflective devices" Part 1. Photo Ming and light signal devices. The technical differences and reasons for this part and ISO 6742-1.2015 are as follows. ---About the scope, use "especially for two-wheel bicycles and GB 17761 electric bicycles that comply with GB 3565 and GB 14746" Instead of "especially for two-wheeled bicycles in accordance with ISO 4210 and ISO 8098" to meet the standards of bicycle products in China Claim; --- Added the term "electric bicycle" to explain the electric bicycle in the scope of this section (see 3.17); --- Added the "rear lights for the vehicle to turn on the power" requirements to remind the rider whether the backlight is lit and play a safety warning role (see 4.3.1.2); --- Increased the light distribution of the cone of the rear light of Figure 3, Figure 3 ~ Figure 6 of the original figure number is adjusted to Figure 4 ~ Figure 7; --- Added Table 3 bicycle low beam distribution "from M to H", "from IL to IR", "from JL to IL and from IR to JR" area The illuminance requirements of the field are required to ensure that the ground in front of the front wheel of the bicycle can be illuminated when the low beam is used at night. This standard has made the following editorial changes. --- Removed the notes of 4.2.2, 4.3.2, 4.8.2 in ISO 6742-1.2015, not applicable to China's standards; ---Modified ISO 6742-1.2015, the ordinate of Figure 4 and Figure 7 is "VV", the abscissa is "HH", and the description of the figure Consistent --- Revised references.
