SLR-30-02
Difference between regulated light source and light source modules
Approved Light Source
(R37, R99, R128)
Light Source Module
Category sheet (RE5)
Submitted to GRE;
approved by GRE and WP29
Does not exist.
A (limited) module description is submitted by the device manufacturer to the approval body
Tolerances (flux, position,..)
Clearly defined in the category sheet
Included in the description ?
COP requirements
Clearly defined in the Regulation and audited by the authority
Do not exist (on module level)
Keying / non-interchangeability
Fully defined in IEC 60061
Keying between modules (of different manufacturers) is not checked
Replaceable
By the car owner etc
Optional, but only by the luminaire maker during repair (?)
„after exchange the photometry shall be met“
SLR-29-06

3. Approved Light Sources and Light Source Modules (R-LSD)
SLR-30 PP
Approved Light Source
(R37, R99, R128)
Light Source Module
Non-replaceable Light Source
Responsibility for approval
LS manufacturer
Luminaire manufacturer (not for the module, but for the luminaire)
Luminaire manufacturer (only for the luminaire)
Category sheet (RE5)
Submitted to GRE;
approved by GRE and WP29
n/a
A (limited) module description is submitted by the device manufacturer to the approval body; the content and structure of the module description is not defined in the regulation
A description is maybe included in internal documentation
Tolerances (flux, position, voltage range..)
Clearly defined in the category sheet
Not required by the regulation.
Tolerances are maybe included in description or internal documentation
Tolerances are maybe included in internal documentation
COP requirements
Clearly defined in the Regulation and audited by the authority
e.g. 350lm +/-20%
Not defined on module level, only on luminaire level
e.g. for DRL minimum 400cd;
maximum 1200cd (800 cd +/- 50%)
Not defined on light source level, only on luminaire level
Keying / non-interchangeability
Fully defined in IEC 60061
Keying between different modules (whether from the same or from different supplier) is not required and not checked during type-approval (only if several modules are used in one luminaire; source: R112 Annex 10)
Designed for replaceability
yes
Optional, “with the use of tools”;
„after exchange the photometry shall be met“ (source: R112 Annex 10)
who is allowed to do the exchange is not defined. no
Road-side replaceability
Mandatory for R37 light sources
Optional for R128 light sources (as indicated in the vehicle manual)
Not specified by the regulation;
Maybe described in the vehicle manual
