DEFINITIONS 3.1 BACKUP LAMP A lighting device used to provide illumination behind the vehicle and to provide a warning signal to pedestrians and other drivers when the vehicle is backing up (reversing) or is about to back up. 3.2 POINT OF VISIBILITY Any point on the lens surfa

10、ce which is within an area bounded by the intersection of the lens surface with a 25 mm diameter cylinder, the centerline of which passes through the light source center and is oriented horizontally and parallel with the longitudinal axis of the vehicle. 4. LIGHTING IDENTIFICATION CODE Backup Lamps

11、may be identified by the code “R” in accordance with SAE J759. 5. TESTS 5.1 SAE J575 is a part of this report. The following tests are applicable with modifications as indicated: 5.1.1 Vibration Test 5.1.2 Moisture Test 5.1.3 Dust Test 5.1.4 Corrosion Test 5.1.5 Photometric Test 5.1.5.1 Photometric

12、tests shall be made with the photometer at a distance of at least 3 m from the lamp. The H-V Axis shall be taken as the horizontal line through the light source and parallel with the longitudinal axis of the vehicle. 5.1.5.2 Photometric measurements shall be made with the bulb filament steadily burn

REQUIREMENTS 6.1 A device when tested in accordance with the test procedures specified in Section 5 shall meet the requirements as speci

14、fied in SAE J575 unless otherwise noted. 6.1.1 Vibration 6.1.2 Moisture 6.1.3 Dust Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-SAE J593 Revised AUG2010 Page 3 of 56.1.4 Corrosion 6.1.5 Photometry 6.1.5.1 The lamps of a two-lamp system shall be de

15、signed to conform to one of the following photometric requirements: a. Each lamp of the pair is tested to the photometric requirements of Figure 1; ORb. When two lamps of the same or symmetrically opposite designs are used, the photometric readings along the vertical axis and the average of the read

16、ings for the same angles left or right of the vertical axis for one lamp may be used to determine compliance with the requirements of Figure 1. ORc. When two lamps of differing designs are used, they shall be tested individually, and the photometric values added shall meet twice the zone total cande

17、la requirements of Figure 1. 6.1.5.2 When only one backup lamp is used on the vehicle, it shall be designed to conform to twice the photometric requirements of Figure 1 and its footnotes. 6.1.5.3 If a backup lamp has portions of its lens which project non white light, that light shall be excluded fr

18、om measurement made to determine compliance with 6.1.5.1 and 6.1.5.2. The lamp or lamps shall be designed to conform to the photometric requirements of this document with white light as defined by 6.2.

FIGURE 1 - PHOTOMETRIC PERFORMANCE REQUIREMENTS Minimum Luminous Intensity(cd) 6.2 Color The color of the light from a backup lamp shall be white, as specified in SAE J578. A backup lamp may project incidental red, yellow, or white light th

20、rough the reflectors or lenses that are adjacent to, close to, or part of the lamp assembly. If alamp has portions of its lens which project non white light, that light shall be regarded as incidental if, when only the nonwhite light is measured at each test point specified in Figure 1, the sum of s

21、uch measurements does not exceed 20% of the sum of the test point measurements of the total light output (white plus nonwhite). 6.3 Material Requirements Plastic materials used in optical parts shall meet the requirements of SAE J576. 6.4 Installation Requirements 6.4.1 Backup lamps shall be mounted

22、 so that the point of visibility of at least one of the lamps is visible from any eye point that is (a) 0.6 to 1.8 m above the horizontal plane on which the vehicle is standing and (b) rearward of a vertical plane perpendicular to the longitudinal axis of the vehicle, 0.9 m to the rear of the vehicl

23、e and extending 0.9 m beyond each side of the vehicle.

24、not be obstructed by any portion of the vehicle unless the lamp is designed to comply with all requirements when the obstruction is considered. 6.4.3 The backup lamp shall be lighted only when the ignition switch is energized and reverse gear is engaged. 7. GUIDELINES 7.1 Installation The following

25、guidelines apply to the backup lamps as used on the vehicle and shall not be considered to be part of the requirements.7.1.1 The luminous intensity of incandescent filament bulbs will vary with applied voltage. The electrical wiring in the vehicle should be adequate to supply design voltage to the l

26、amp filament. 7.1.2 Performance of lamps may deteriorate significantly as a result of dirt, grime and/or snow accumulation on their optical surfaces. Installation of lamps on vehicles should be considered to minimize the effect of these factors. 7.1.3 Where it is expected that lamps must perform in

27、extremely severe environments, such as off-highway, mining or fuel haulage, or where it is expected that they will be totally immersed in water, the user should specify lamps specifically designed for such use. 7.2 For requirements and gauges to be used in socket designs, refer to SAE J567. 7.3 For

28、additional information on photometric test accuracy guidelines, refer to SAE J1330. 8.
