16、ea means the area of the orthogonal projection of the effective light-emitting surface of a lamp on a plane perpendicular to a defined direction relative to the axis of reference. Unless otherwise specified, the direction is coincident with the axis of reference. 3.2 EFFECTIVE LIGHT-EMITTING SURFACE
17、 Effective light-emitting surface means that portion of a lamp that directs light to the photometric test pattern, and does not include transparent lenses, mounting holes bosses, reflex reflector area, beads or rims that may glow or produce small areas of increased intensity as a result of uncontrol
18、led light from an area of 1/2 degree radius around a test point. That area of the light emitting surface projected on a plane at right angles to the axis of a lamp, excluding reflex reflectors (but including congruent reflexes), which is not obstructed by opaque objects such as mounting screws, moun
19、ting rings, bezels, trim, or similar ornamental feature areas. Areas of optical or other configurations, for example, molded-optical rings or markings, shall be considered part of the total effective projected luminous lens area. The axis of the lamp corresponds to the H-V axis used for photometric
20、requirements. 4. LIGHTING IDENTIFICATION CODE 4.1 Turn signal lamps for use on vehicles 2032 mm or more in overall width may be identified by the code: 4.1.1 “I6” for a rear-mounted turn signal lamp and for a front-turn signal lamp mounted 100 mm or more from the lighted edge of a lower beam headlam
21、p, as measured from the optical center of the turn signal, in accordance with SAE J759. 4.1.2 “I7” for a front-mounted turn signal lamp mounted less than 100 mm from the lighted edge of a lower beam headlamp, as measured from the optical center of the turn signal, in accordance with SAE J759. 4.1.3
22、“S2” for Stop lamps for use on vehicles 2032 mm or more in overall width, in accordance with SAE J759. 5. TESTS 5.1 SAE J2139 is a part of this document.

SAE INTERNATIONAL J2261 JUL2016 Page 4 of 10 5.1.5.4 Photometric Measurement Flashing Mode When measuring LED devices, or the need to take precautions to avoid overheating, the lamps may be measured in the flashing mode. 5.1.5.4.1 In the case of LED dev
25、ices this must be achieved with a switching frequency of 1.5 Hz 0.5 Hz with a pulse width greater than 0.3 seconds, measured at 95% peak light intensity. 5.1.5.4.2 In the case of replaceable filament lamps, they shall be operated at reference luminous flux during on time.

When a tail lamp or a clearance lamp is combined with a stop or turn signal lamp and the maxi
31、mum intensity of the tail lamp or clearance lamp is located below the horizontal and is within an area generated by a 1.0 degree radius around the test point, the ratio for the test point may be computed using the lowest value of the tail lamp or clearance lamps luminous intensity within the generat
