DEFINITIONS 3.1 TAIL LAMP Tail Lamp (Rear Position) - Whether separate or in combination with other lamps, tail lamps are located on both the left and right rear of a vehicle to indicate the presence and width

15、of a vehicle by a steady operating, low intensity light when viewed from the rear. 3.2 The terminology contained in SAE J387 shall apply to this standard. 4. LIGHTING IDENTIFICATION CODE Tail lamps for use on vehicles 2032 mm or more in overall width may be identified by the code “T2” in accordance

16、with SAE J759. 5. TESTS 5.1 Tests for Lighting Devices, Reflective Devices, and Components Used on Vehicles 2032 mm or More in Overall Width SAE J2139 is a part of this document. The following tests are applicable with modification as indicated. 5.1.1 Vibration 5.1.2 Moisture 5.1.3 Dust 5.1.4 Corros

17、ion SAE INTERNATIONAL J2040 JAN2016 Page 4 of 8 5.1.5 Photometry Photometric measurements shall be made with the light source of the device at least 3 m from the photometer. 5.1.5.1 The H-V axis of the device shall be taken to be parallel to the longitudinal axis of the vehicle, when the device is m

18、ounted in its design position. 5.1.5.2 Photometric measurements shall be made with the light source steadily burning. Photometric measurements of multiple lamp arrangements may be made by either of the following methods. 5.1.5.2.1 All lamps shall be photometered together provided that a line from th

19、e light source of each lamp to the center of the photometer sensing device does not make an angle of more than 0.6 degrees with the photometer H-V axis. When lamps are photometered together, the H-V axis shall intersect the midpoint between the extreme light sources. 5.1.5.2.2 Each lamp shall be pho

20、tometered separately by aligning the axis of each lamp with the axis of the photometer. The photometric measurement for the entire multiple lamp arrangement shall be determined by adding the photometric outputs from each individual lamp at its corresponding test point. 5.1.5.3 The test methods and p

21、rocedures of SAE J1889 shall also be applied if LED light sources are present in the lamp. 5.1.6 Warpage Test on Devices with Plastic Components 5.2 Color SAE J578 is a part of this document. 5.3 Plastic Materials SAE J576 is a part of this document. 6. REQUIREMENTS 6.1 Performance Requirements The

22、device when tested in accordance with the test procedures of this document shall meet the requirements of SAE J2139 or as indicated. 6.1.1 Vibration 6.1.2 Moisture 6.1.3 Dust 6.1.4 Corrosion 6.1.5 The lamp shall be designed to conform to the zone total photometric requirements of Figure 1 and its fo

23、otnotes. The summation of the luminous intensity measurements at the test points in a zone shall be at least the value shown. 6.1.5.1 An arrangement of lamps may be used to meet the photometric requirements of Figure 1 provided the distance between adjacent light source does not exceed 560 mm for tw

24、o lamp arrangements or does not exceed 410 mm for multiple lamp arrangements. If the distance between light sources exceeds those distances detailed previously then, each lamp shall individually comply with the photometric requirements of Figure 1.

25、1 - PHOTOMETRIC REQUIREMENTS MINIMUM LUMINOUS INTENSITY (cd) SAE INTERNATIONAL J2040 JAN2016 Page 6 of 8 6.1.5.2 When a tail lamp is combined with the stop lamp or turn signal lamp, the stop lamp or turn signal lamp intensity shall be not less than three times the luminous intensity of the tail lamp

26、 at any test point, except that at H-V, H-5L, 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 tail lamp. When a tail lamp is combined with the stop lamp or turn signal lamp, and the maximum luminous intensity of the tail lam

27、p is located below the horizontal and is within an area generated by a 1.0 degree radius around the test point, the ratio for the test point may be computed using the lowest value of the tail lamp intensity within the generated area. 6.1.6 Warpage 6.2 Color The color of the light measured from the t

28、ail lamp shall meet red as specified in SAE J578. 6.3 Plastic Materials The plastic materials used in the optical parts shall meet the requirements of SAE J576. 6.4 Design Requirements 6.4.1 If a tail lamp is optically combined with a stop lamp or a turn signal lamp and a replaceable multiple light

29、source is used, the light source retention system shall be designed with an indexing means so 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 lamp housing in a random position, unless the la

30、mp will perform its intended function with random light source orientation. 6.4.2 The effective projected luminous lighted lens area of a single lamp shall be at least 75 cm2. 6.4.3 A tail lamp shall not be optically combined with a clearance lamp. 6.5 Installation Requirements The tail lamp shall m

31、eet the following requirements as installed on the vehicle. 6.5.1 The tail lamps shall be mounted on the permanent structure of the vehicle, facing rearward, at the same height and spaced as far apart laterally as practicable, so that the signal will be clearly visible. 6.5.2 Each tail lamp shall be

32、 designed to comply with all photometric requirements of Figure 1 with all vehicular obstructions considered. 6.5.3 Each tail lamp installed shall comply with one of the following visibility requirements. (Left hand shown, right hand symmetrically opposite) 6.5.3.1 Each tail lamp must provide a mini

33、mum of 13 cm2of unobstructed projected area when the light emitting surface area of the lens, excluding reflex reflector area, is projected parallel to a horizontal plane in any direction from 45 degrees outboard to 45 degrees inboard of the vehicle longitudinal axis, and parallel to a longitudinal

34、vertical plane from 15 degrees above to 15 degrees below the horizontal; (see Figure 2).

GUIDE

36、LINES 7.1 Installation Guidelines 7.1.1 Performance of lamps may deteriorate significantly as a result of dirt, grime, snow, and ice accumulation on the optical surfaces, therefore installation of the device on the vehicle should be considered to minimize the effects of these factors. 7.1.2 When det

37、ermined that the device must perform in extremely severe environments, or when it is expected to be totally immersed in water, the user should specify devices specifically designed for such use. 7.1.3 The luminous intensity of the light source may vary with applied voltage, therefore consideration o

38、f the electrical wiring design should be to supply adequate lamp voltage. SAE INTERNATIONAL J2040 JAN2016 Page 8 of 8 8.
