33、tive lighting system providing forward illumination comprised of one or more headlamps, discharge light sources, ballast/starting system and interconnecting wiring. 3.2 DISCHARGE SOURCE An electric light source in which light is produced by a stabilized arc. 3.3 RUN-UP TIME The period of time betwee

34、n when the DFL system is switched ON and when the DFL system reaches a specified output level. 3.4 HOT RESTRIKE The ability of a DFL system to restart operation, within a specified time period, after being switched OFF from a steady state (“hot”) condition. 3.5 PHOTOMETRIC MAINTENANCE Change in lumi

35、nous intensity (DFL system) or luminous flux ( light source) during operational life. 3.6 SUBSYSTEM A component or assembly of components, which comprise a portion of the entire system (assembly). 3.7 LIGHT SOURCE RATED LABORATORY LIFE A claim made by the manufacturer of operating time and starting

36、cycles, under laboratory test conditions, over which at least 50% of the light sources will meet the life test performance specifications in this standard. 3.8 COLOR RENDERING INDEX (CRI) Measure of the degree of color shift objects undergo when illuminated by the light source as compared with the c

37、olor of those same objects when illuminated by a reference source of comparable color temperature. 3.9 ULTRAVIOLET RADIATION Radiation in the spectral region between 100 and 400 nm. Definitions and terminology are adopted in accordance with IES RP-27.1-05. 3.10 STEADY-STATE A condition under which t

38、he light output of the device is considered to be stable or changing at such a slow rate as to be insignificant. This condition is generally measured in terms of a maximum percent change per time period. Steady-state parameters are established by allowing the system to operate for a designated time

39、after being switched ON. 3.11 AUTOMOTIVE BALLAST A device for stabilizing the operating characteristics of a discharge lamp. The ballast contains all the necessary circuitry to start a lamp and cause it to operate within a specified power profile range. It controls the required light output characte

40、ristics of the automotive discharge lighting system. The ballast may consist of one or more separate components. SAE INTERNATIONAL J2009 AUG2016 Page 6 of 17 3.12 SPECTRAL IRRADIANCE EO(O) The spectral concentration of irradiance in accordance with ANSI/IESNA RP-16-96. 3.13 SPECTRAL LUMINOUS EFFICIE

LIGHTING IDENTIFICATION CODES, MARKINGS, AND NOT

42、ICES 4.1 Lamps may be marked in accordance with SAE J759 for the applicable forward lighting system and discharge system, “HG”. 4.2 The DFL system shall contain a label indicating the presence of high voltage, e.g., the international electric shock hazard symbol (“lightning bolt”) per ANSI Z535.4 -

43、Product Safety Signs and Labels. 4.3 Subsystem components shall be marked per 49 CFR 564 Replaceable Light source Information (Part 564) for light sources and ballast subsystems. 4.4 If applicable, subsystem components shall be marked for mercury content per ANSI Z535.4 - Product Safety Signs and La

44、bels. 5. TESTS Unless otherwise indicated, all sample DFL systems shall be seasoned at design voltage and steady operation for 20 h prior to being subjected to the tests that follow. Alternatively, these tests shall be carried out with light sources which have been seasoned for a minimum of 15 cycle

45、s having the following switching cycle: 45 minutes on, 15 seconds off, 5 minutes on, 10 minutes off. The power supply used in a test shall be capable of supplying the proper current the subsystem requires during the specified conditions. A new DFL system may be used for each test. 5.1 Light Source P

46、hotometry 5.1.1 Nominal Operating Position The nominal operating position shall be horizontal within 10 degrees with the lead wire down. Seasoning and testing positions shall be identical. If the lamp is accidentally operated in the wrong direction, it shall be re-seasoned before measurements begin.
