9、of Objects by Using the CIE System SAE J2139 Revised MAR2001 -2- 3.Definitions 3.1Discharge Signal Lighting (DSL) SystemA vehicular lighting system used in signal and marking applications. The DSL system is composed of a discharge light source, interconnecting wiring, and a signal or marking lightin
10、g assembly. 3.2Discharge Light SourceAn electric light source in which light is produced by a stabilized electric discharge through an ionized gas. The light source consists of a sealed glass/tube envelope wall and ballast. The size, shape, and color will depend on the application. (For example, but
11、 not limited to: neon, or fluorescent lamps.) 3.3Light Emitting Diode (LED) Lighting DeviceA lighting device in which light is produced by an LED or an array of LEDs. 3.4Lighting Device Light CenterThe geometric center of the light source or sources used to illuminate the device function or the geom
12、etric center of the illuminated area if the light output is produced indirectly. 3.5Incandescent Lighting DeviceA lighting device in which light is produced by a filament being heated to incandescence by an electrical current. 3.6Integrated Electronic ComponentElectronic component(s) integrated with
13、in the housing of the lamp assembly or physically inseparable from the lighting device used to produce the desired output. 3.7SampleSamples submitted for test shall be representative of the device as regularly manufactured and marketed. Each sample shall be securely mounted on the test fixture in it
14、s design position and shall include all accessory equipment necessary to operate the device in its normal manner. 3.8Sealed Lighting DevicesLighting devices that do not allow the passage of gas or water between the interior environment and the exterior environment. 3.9Test FixtureFixture specificall
15、y designed to support the device in its designed operating position during a laboratory test. 3.10 Vibration Test FixtureA fixture specifically designed to support the device in its operating position during the vibration test. The fixture shall not have a resonant frequency in the test range. 4.Tes
16、tsThe following sections describe the individual tests which need not be performed in any particular sequence, except as noted in the test procedure. Unless otherwise specified all tests will be done at an ambient room temperature of 25 C 5 C. The completion of the tests may be expedited by performi
17、ng the tests simultaneously on separately mounted samples. However, it is recommended that the design of each device be evaluated to determine if the vibration test or the warpage test affect other tests, in which case, those tests shall be performed first. 4.1Vibration TestThis test evaluates the a
18、bility of the sample device to resist damage from vibration-induced stresses. This test is not intended to test the vibration resistance of bulb filaments, but may be used to evaluate the effects of vibration-induced stresses on shock-mounted devices. 4.1.1VIBRATION TEST EQUIPMENT 4.1.1.1See SAE J57
19、7 JUN73 for details of vibration test machine. SAE J2139 Revised MAR2001 -3- 4.1.2VIBRATION TEST PROCEDURES 4.1.2.1The DUT (Device Under Test), as mounted on the support supplied, shall be bolted to the anvil end of the table of the vibration test machine and vibrated at 750 cpm 10 cpm through a dis
20、tance of 3 mm 0.25 mm. The table shall be spring mounted at one end and fitted with steel calks on the underside of the other end. These calks are to make contact with the steel anvil once during each cycle at the completion of the fall. The rack shall be operated under a spring tension of 27.3 kg t
21、o 31.7 kg. 4.1.2.2Test duration is 60 +1/0 minutes. 4.2Moisture Test 4.2.1WATER-SPRAY MOISTURE TESTThis test procedure shall be used to test the ability of the device to resist moisture leakage into the device from a water spray and to determine the drainage capability of the device with drain holes
22、 or other exposed openings in the device. Devices tested to 4.2.2 and complying with 5.2.2 of this document can be excluded from this test. 4.2.1.1Water-Spray Moisture Test Equipment 4.2.1.1.1The water-spray cabinet shall be equipped with one or more nozzles which provides a solid cone of water spra
23、y of sufficient included angle to completely cover the DUT. The centerline of the nozzle shall be directed downward at an angle of 45 degrees 5 degrees to the vertical axis of the rotating test platform. 4.2.1.1.2The precipitation rate of the water spray at the DUT shall be 2.5 +1.6/0.0 mm minimum p
24、er minute as measured with a vertical cylindrical collector centered on the vertical axis of rotation. The collector shall be 100 mm high and the inside diameter shall be a minimum of 140 mm. 4.2.1.1.3The DUT shall rotate about its vertical axis at a rate of 4.0 rpm 0.5 rpm. 4.2.1.2Water-Spray Moist
