18、. TMC RP-702 C Trailer Lamp and Reflector Placement 3. DEFINITIONS 3.1 CLEARANCE LAMP A clearance lamp provides light to the front or rear of a vehicle to indicate the overall width and height. 3.2 SIDEMARKER LAMP Lighting devices used to indicate the presence and length of the vehicle by a steady o

19、perating, low intensity light when viewed from the side. 3.3 IDENTIFICATION LAMP A group of three lamps in a horizontal row which provide light to the front or rear or both, to identify vehicles 2032 mm or more in overall width. 3.4 COMBINATION CLEARANCE AND SIDEMARKER LAMP A combination clearance a

20、nd sidemarker lamp is a single lamp which simultaneously meets the requirements of a clearance and a sidemarker lamp. 3.5 For additional definitions refer to SAE J387 Terminology-Motor Vehicle Lighting 4. LIGHTING IDENTIFICATION CODE 45 degrees left to 45 degrees right. Zone totals should be reduced

21、 by the values at these test points, as listed in Figure 2, when testing a lamp for this application. The summation of the luminous intensity measurements at the test points in a zone shall be at least the value shown. SAE INTERNATIONAL J2042 Revised FEB2014 Page 5 of 8 1. The maximum luminous inten

22、sity for rear lamps only is 18 cd within the photometric pattern shown. 2. Ratio requirements of 6.1.5.1 apply. 3. Photometric requirements of 6.1.5 apply. 4. Combination clearance and sidemarker lamps shall conform with both clearance and sidemarker lamp photometric requirements. 5. The measured va

23、lues at each test point shall not be less than 60% of the required minimum value shown for that individual test point location. 6. The sum of the luminous intensity measurements at each test point within a zone shall not be less than the zone total shown. The luminous intensity measurements at each

24、discrete test point shown within the corresponding zone are the values used to calculate the specified zone total. 7. The listed maximum shall not be exceeded over any area larger than that generated by a 0.5 radius within the solid angle defined by the test points. When red clearance lamps are opti

25、cally combined with stop lamp and turn signal lamps, the maximum applies only on or above the horizontal. FIGURE 1 - PHOTOMETRIC REQUIREMENTS (RED) Minimum Luminous Intensity (cd) SAE INTERNATIONAL J2042 Revised FEB2014 Page 6 of 8 1. Ratio requirements of 6.1.5.1 apply. 2. Photometric requirements

26、of 6.1.5 apply. 3. Combination clearance and sidemarker lamps shall conform with both clearance and sidemarker lamp photometric requirements. 4. The measured values at each test point shall not be less than 60% of the required minimum value shown for that individual test point location. 5. The sum o

27、f the luminous intensity measurements at each test point within a zone shall not be less than the zone total shown. The luminous intensity measurements at each discrete test point shown within the corresponding zone are the values used to calculate the specified zone total. FIGURE 2 - PHOTOMETRIC RE

28、QUIREMENTS (YELLOW) Minimum Luminous Intensity (cd) 6.1.5.1 When a clearance lamp is combined with a stop lamp or a turn signal lamp, the stop lamp or turn signal lamp intensity shall be not less than three times the luminous intensity of the clearance lamp at any test point, except that at H-V, H-5

29、L, H-5R, and 5U-V, the stop lamp or turn signal lamp intensity shall be not less than five times the luminous intensity of the clearance lamp. 6.1.6 Warpage 6.1.6.1 Lamps utilizing LED light sources should meet SAE J1889 Thermal Cycle test. 6.2 Color The color of the light from the front clearance l

30、amps, the front identification lamps, and the front and intermediate sidemarker lamps shall be yellow. The color of the light from the rear clearance lamps, rear identification lamps, and the rear sidemarker lamp (aka a tracking lamp on a trailer) shall be red. The color shall meet the requirements

33、 may be combined with a side turn signal lamp. 6.4.6 A clearance lamp, identification lamp, or a sidemarker lamp may be combined with a reflex reflector. 6.4.7 If a clearance lamp is combined with a turn signal lamp or a stop lamp, or if a sidemarker lamp is combined with a side turn signal lamp, an

34、d a replaceable multiple light source is used, the light source retention system shall be designed with an indexing feature in order to insure that the light source is properly indexed. Removable light source retention systems shall have an indexing feature so that they cannot be reinserted into the

35、 lamp housing in a random position, unless the lamp will perform its intended function with random light source orientation. 6.5 Installation Requirements 6.5.1 Clearance lamps shall be mounted on the permanent structure of the vehicle as near as practicable to the upper left and right extreme edges

36、 of the vehicle. 6.5.2 Sidemarker lamps shall be mounted on the permanent structure of the vehicle not less than 380 mm above the road surface measured from the center of the device at vehicle curb weight. An intermediate yellow sidemarker lamp shall be mounted at the midpoint on vehicles 7.6 m or m

37、ore in overall length. The red, rear sidemarker lamp, used on vehicles, also referred to as a tracking lamp, shall be mounted on the permanent structure of the vehicle not less than 380 mm nor more than 1525 mm above the road surface measured from the center of the lamp at trailer curb weight. 6.5.3

38、 Identification lamps shall be mounted on the permanent structure of the vehicle as near as practicable to the vehicle centerline and to the top of the vehicle having a light center spacing of not less than 150mm nor more than 300mm apart. 6.5.4 When the rear identification lamps are mounted at the

39、extreme height of the vehicle, rear clearance lamps need not meet the requirement that they be mounted as close as practicable to the top of the vehicle. 6.5.5 The lamps shall be designed to comply with all photometric requirements of Figure 1 (red) and Figure 2 (yellow) as installed on the vehicle,

40、 with all vehicular obstructions considered, except that yellow clearance and identification lamps that are roof mounted need not meet the photometric requirements of 20 degrees down, 45 degrees left to 45 degrees right. SAE INTERNATIONAL J2042 Revised FEB2014 Page 8 of 8 7. GUIDELINES 7.1 Installat

41、ion Guidelines The following guidelines apply to devices used on the vehicle and shall not be considered part of the requirements. 7.1.1 Performance of the lamps may deteriorate significantly as a result of dirt, grime, snow, and ice accumulation on the optical surfaces. Installation of the device o

42、n vehicles should be considered to minimize the effect of these factors. 7.1.2 In instances where severe environments are expected, such as in off-highway, mining, fuel haulage, or where it is expected to be totally immersed in water, the user should specify devices specifically designed for such us

43、e. 7.1.3 When auxiliary lamps are mounted near identification lamps, the distance from the closest identification lamp shall be greater than twice the spacing between the identification lamps. 8.
