23、.1 BULBS An indivisible assembly which contains a source of light and which is normally used in a lamp. Unless otherwise specified, bulbs used in the tests shall be supplied by the test facility and shall be representative of bulbs in regular production. Where special bulbs are specified, they shall
24、 be submitted with the sample devices and the same or similar bulbs shall be used in the tests. Lighting devices designed for use in 6 V, 12 V, or 24 V systems shall be tested with 12 V system bulbs. 3.2 LIGHTING DEVICES An assembly (divisible or indivisible) which contains a bulb or other light sou
25、rce and generally an optical system such as a lens or a reflector, or both, and which provides a lighting function. Lighting device samples submitted for test shall be representative of the device as regularly manufactured and marketed, unless otherwise identified. Each sample shall be securely moun
26、ted on a test fixture in its designed operating position and shall include all accessory equipment necessary to operate the device in its normal manner. 3.3 TEST FIXTURE A device specifically designed to support the lighting device in its designed operating position during laboratory testing. This f
27、ixture, when used for the vibration test, shall not have a resonant frequency in the 10 to 250 Hz range. 4. TESTS The following sections describe individual tests which do not need to be performed in any particular sequence. The completion of the tests may be expedited by performing the tests simult
28、aneously on separately mounted samples. However, it is recommended that the design of each device be evaluated to determine if vibration or warpage tests might affect the results of other tests, in which case the vibration and/or warpage test(s) should be performed first. 4.1 Photometry Test This te
29、st measures luminous intensities at test points throughout the light distribution pattern as specified by the applicable SAE report for the sample device. 4.1.1 Photometric Test Equipment Unless otherwise specified, the following equipment shall be used to make the photometric measurements: 4.1.1.1
30、Positioner The positioner (goniometer) configuration shall be capable of positioning the sample device at the test point positions specified in 4.1.2.4 and in the applicable SAE report. (The recommended configuration is shown in SAE J1330.) Other systems may be used to achieve equivalent positioning
31、, but it may be necessary at compound angles greater than 5 degrees from H-V to calculate the position which is equivalent to that of the recommended goniometer. SAE INTERNATIONAL J575 AUG2015 Page 5 of 23 4.1.1.2 Photometer The photometer system consists of a sensor, amplifier, and indicator instru
32、ment. The system shall be capable of providing the luminous intensity readings (candela) of the output of the device being tested. The sensor shall be located at the distance from the device specified in the applicable SAE report and shall have the following characteristics: 4.1.1.2.1 Maximum Size U
33、nless otherwise specified, the maximum effective area of the sensor shall fit within a circle whose diameter is equal to 0.009 times the actual test distance from the light source of the sample device to the sensor. The sensor effective area is the actual area of intercepted light striking the detec
34、tor surface of the photometer. For systems with lens(es) that change the diameter of the intercepted light beam before it reaches the actual detector surface, the maximum size requirements shall apply to the total area of the light actually intercepted by the lens surface. The sensor shall be capabl
35、e of intercepting all direct illumination from the largest illuminated dimension of the sample device at the test distance. 4.1.1.2.2 Photopic Response The color response of the photometer sensor shall be corrected to that of V(O) as referenced in ASTM E 308-85. 4.1.2 Photometry Test Procedure The s
36、ample device shall be mounted on a test fixture and luminous intensity measurements made as follows: 4.1.2.1 Bulbs Unless otherwise specified, for lamps requiring incandescent bulbs, accurate rated bulbs (selected per SAE J387) shall be used and shall be operated at their rated luminous flux output.
37、 Where specified in the lamp design, other types of light sources or special bulbs may be used and operated at their rated luminous flux output and/or design voltage as appropriate after seasoning per SAE J387 shall be used only where appropriate for the light source type. Test Voltage 4.1.2.1.1 Whe
38、re light source(s) listed in SAE J573 and/or SAE J2560 and/or SAE J2650/J1889 and/or ECE R37 are used, and where the lamp does not have voltage modification circuitry, the light source(s) shall be energized so that they produce the rated (reference) luminous flux mentioned in the standards above (Fi
39、gures 1A and 1D). 4.1.2.1.2 Where light source(s) not listed in the standards above are used without voltage modification circuitry, they shall be seasoned per SAE J387 and operated at the rated (reference) luminous flux specified by the manufacturer of the light source(s). If the rated (reference)
40、luminous flux output is not available, operate the light source(s) at the design voltage specified by the lamp manufacturer (Figures 1A and 1D). 4.1.2.1.3 Where the lamp is designed to operate with integral voltage modification circuitry, operate the lamp at the design voltage specified by the lamp
41、manufacturer applied to the input of the lamp (Figure 1B). 4.1.2.1.4 Where the lamp is designed to operate with separate circuitry designed to modify vehicle operating voltage applied to the lamp, operate the lamp with this circuitry or circuitry with equivalent output and with the vehicle voltage a
42、pplied to the input of the modification circuitry (Figure 1C). 4.1.2.1.5 Where the lamp is designed specifically for a vehicle with a stabilized network (e.g., Pulse Width Modulation PWM), operate the lamp with the voltage specified by the vehicle manufacturer applied to the input of the lamp (Figur
43、es 1A and 1D). 4.1.2.1.6 Where the lamp is a sealed beam or a lamp comprised of a light source permanently sealed inside the lens and housing (reflector) with no additional circuits, operate the lamp with the voltage specified by the lamp manufacturer applied to the inputs of the lamp (Figure 1D). S
44、AE INTERNATIONAL J575 AUG2015 Page 6 of 23 Figure 1 - Lamp configurations for applying photometric test voltage 4.1.2.2 Test Distance The luminous intensity measurements shall be made at a distance equal to, or greater than, the minimum test distance between the center of the light source (or the fa
45、ce of a reflex reflector) and the photometer sensor as specified in the SAE document applicable to the function of the sample device. If no distance is specified, a distance of at least 3.05m (10ft) from the photometer is required for signal lighting, 18.3m (60ft) for forward lighting, and 30.5m (10
46、0ft) for reflex reflectors. The aperture of the receiving photocell shall be no greater than 1/1000 of the measuring distance. 4.1.2.3 Test Point Positions Test point positions are specified in the applicable SAE document. The following nomenclature shall also apply: The letters “V” and “H” designat
47、e the vertical and horizontal planes intersecting both the device light source (or center of a reflex reflector) and the goniometer axis. A device using a bulb with a major and minor light source shall be oriented with respect to its major light source. “H-V” designates the test point angle at the i
48、ntersection on the H and V planes (H = 0, V = 0 degrees). Unless otherwise specified, the intersection shall be parallel to the longitudinal axis of the vehicle in the case of the designed operating position of front and rear device functions and shall be horizontal and perpendicular to the longitud
49、inal axis of the vehicle in the case of side function devices. The letters “U”, “D”, “L”, and “R” (up, down, left, and right, respectively) designate the angular position in degrees from the H and V planes to the goniometer as viewed from a lamp, or to the source of illumination as viewed from a reflex reflector. This angular direction is defined as follows: 4.1.2.3.1 Horizontal Angle (L and R) The angle between the vertical pla
