5、the new more user-friendly photometry format balloted and approved in June 2006. There are no photometry requirements changes to this document. The current Table 1, Photometry Requirements is replaced with Figure 1, Photometry Requirements and current Figure 1, Test Point Orientation is changed to F
6、igure 2. Corresponding references to them in paragraph 6.1.5 are also changed. In the new Figure 1 the area defined by: 10U to 90U45L to 45R is now identified as Zone 1 and the Note 2 scan is shown as “A scan shall be performed in 1-degree increments both horizontally and vertically. If any point ex
7、ceeds 125 cd during the scan, a maximum of 500 cd is permissible if contained within a 2 degree conical angle.” which is the same procedure as currently in SAE J583 Front Fog Lamp. Also, the 4U, 2U, 1U and H45L to 85R are identified as Lines 1, 2, 3 and 4 respectively and Note 3 states: “All-line sc
8、ans are to be performed an lines 1, 2, 3 and 4 for maximum cd,” which is also the same note as used in SAE J583. 1. SCOPE This SAE Recommended Practice provides test procedures, performance requirements, and guidelines for front cornering lamps intended for use on motor vehicles. 2. REFERENCES 2.1 A

DEFINITIONS 3.1 Front Cornering Lamps Steady burning lamps used in conjunction with the turn signal system to supplement the headlamps by providing additional illumination in the direction of turn. They may be used independent of the turn signal to ease mane

IDENTIFICATION CODE DESIGNATION Front cornering lamps meeting the performance requirements of this document may be identified by the code K in accordance with SAE J759. 5. TESTS 5.1 SAE J575 is a part of this document. The following tests are applicable with the modifi
14、cations as indicated. 5.1.1 Vibration Test 5.1.2 Moisture Test 5.1.3 Dust Exposure Test 5.1.4 Corrosion Test 5.1.5 Photometry Test In addition to the test procedures in SAE J575, the following apply: 5.1.5.1 Photometry measurements shall be made with the light source of the lamp at least 3 m from th
15、e photometer. The H-V axis shall be taken as the horizontal line through the light source and perpendicular to the longitudinal axis of the vehicle. 5.1.6 Warpage Test on Device with Plastic Components 5.2 Color Test SAE J578 is a part of this document. 5.3 Plastic Materials SAE J576 is a part of th
16、is document. 6. REQUIREMENTS 6.1 Performance Requirements A device tested in accordance with the test procedure specified in Section 5 shall meet the following requirements: 6.1.1 Vibration SAE J575. 6.1.2 Moisture SAE J575.

The lamp shall be designed to conform to the photometry requirements contained in Figure 1. NOTE: Test poi
18、nts shown are for a lamp mounted on the left side of the vehicle L and R designations in Figure 1 should be reversed for a lamp mounted on the right side of the vehicle. Refer to Figure 2 for Test Point Orientation. 6.1.6 Warpage SAE J575. 6.1.7 Color Requirements The color of the light from a front
19、 cornering lamp shall be white to yellow as specified in SAE J578. 6.2 Material Requirements Plastic materials used in optical parts shall meet the requirements of SAE J576. 7. GUIDELINES The following guidelines apply to front cornering lamps as used on motor vehicles and should not be considered p
20、art of the requirements. 7.1 The front cornering lamps are intended for use only when the headlamps are operational. 7.2 Cornering lamp activation should coincide with turn signal activation to provide illumination in the direction of the intended turn. 7.3 Cornering lamps may be deactivated at high
21、 vehicle speed (lane change maneuver) or while stopped, to avoid discomfort to other road users. 7.4 Cornering lamp may be activated by steering angle. 7.5 Location Requirements The mounting height of the front cornering lamps shall be from 305 mm to 760 mm above the ground as measured from the opti
22、cal center of the lamp on an unloaded vehicle. 7.6 For requirements and gauges to be used in socket designs, refer to SAE J567.
