SLR-30-22 Light sources in RID

„4.5. Light sources“ With the agreed objective to allow all light source technologies in all lamps (functions) the text of section 4.5.1. condenses significantly 4.5. Light sources 4.5.1. Restrictions on light sources  The lamps shall only be equipped with UN approved light source(s), provided that no restriction on the use is made at the time of application for type approval, and/or light source module(s), and/or non- replaceable  light source(s). [Where  more than one light source is used to provide a beam, the correlated colour temperatures of these light sources shall not deviated more than [1000] K.] [In the case of LED modules where the requirements of Annex 9 shall apply; compliance with these requirements shall be tested .] Additional  light sources may be used inside the “passing beam headlamp” to contribute to bend lighting and for the purpose of generating infrared radiation. … Where  more than one light source is used to provide the driving beam, these light sources shall be operated simultaneously. In such case … 4.5.2. General requirements for light sources (e.g. fixation, 2000lm limit, …) 4.5.3. Specific requirements for light sources (e.g. minimum source flux, …) New core text Such restriction needed? Would becomes part of test annex Leftover from old 4.5.1. To be carried over ?

„4.6. Testing of the lamp“ Different from the sections 4.7., 4.8., … the section 4.6. is covering testing aspects dealing with light sources only”. This technology-depending test requirements are moved to a new annex. Body Text: “Tests shall be carried out according to Annex X.” 4.6. Testing of the lamp with respect to light sources 4.6.x. In the case of … (filament, LED, non-replaceable, …, test voltages, …) 4.7. Testing of light transmitting components … 4.8. Testing of cut-off … 4.9. Tests for stability of photometric performance … … all in 4.6. to be carried over to Annex X What to do with other kind of testing requirements

„5.1. Driving beams“ Specific requirements are added per lamp (function), listing the time interval when the beam requirements have to be met 5.2. Technical requirements concerning driving-beam of the Class … 5.2.x. Photometric requirements Referring to Figure A4-II the luminous intensity distribution of the driving-beam shall meet the following requirements … 5.2.x.1. [Timing requirements] The required luminous intensities shall be fulfilled in the period between [1] minute after activation and photometric stability. In the period between [1] second and [1] minute after activation the driving-beam shall have a minimum luminous intensity in the reference point HV of [25]% of the intensity measured after photometric stability. This is required today in LED case This closes the “loop”. It is derived from HID case today.

„5.2. Passing beams“ Specific requirements are added per lamp (function), listing the time interval when the beam requirements have to be met 5.2. Technical requirements concerning headlamps to provide a passing-beam of Class … 5.2.x. Photometric requirements The passing-beam shall meet the luminous intensities at the test points referred to in Table 8 and in Figures A4-V or A4-VI … 5.2.x.1. [Timing requirements] The required luminous intensities shall be fulfilled in the period between [1] minute after activation and photometric stability. In the period between [4] seconds and [1] minute after activation the passing-beam shall have a minimum luminous intensity in the “reference point” 50V of [80]% of the intensity measured after photometric stability. This is required today in LED case This closes the “loop”. It is derived from HID case today.

Annex X „Testing [with respect to light sources]“ The new Annex X contains statements like the following example of filament/incandescent technology … The luminous intensity distribution is measured after photometric stability. The luminous intensity distributions at other points in time is calculated from the luminous intensity distribution measured after photometric stability by applying at each test point the ratio of luminous intensities measured at the reference point of the lamp (function) under consideration. In case of filament technology [Tests are carried out after photometric stability.] All lamps (functions) are deemed to [inherently] comply with minimum and maximum intensity requirements in the period between [200] milliseconds after activation and photometric stability, if the values measured after photometric stability are compliant. In case of a lamp (function) having specific requirements in the period before [200] milliseconds after activation, additional tests [or: measurements] are carried out at the required point(s) in time. … and covers the existing requirements from 4.6.x In the case of replaceable filament light sources … In the case of modules … See IEC 62493 as example (L3-0190)

Annex X „Testing [with respect to light sources]“ The new Annex X contains statements like the following example of gas-discharge technology … The luminous intensity distribution is measured after photometric stability. The luminous intensity distributions at other points in time is calculated from the luminous intensity distribution measured after photometric stability by applying at each test point the ratio of luminous intensities measured at the reference point of the lamp (function) under consideration. In case of gas-discharge technology [Tests are carried out after photometric stability.] All lamps (functions) are deemed to [inherently] comply with minimum and maximum intensity requirements in the period between [1] minute after activation and photometric stability, if the values measured after photometric stability are compliant.
