Photobiological safety of lamps and lamp systems - Part 2:
Guidance on manufacturing requirements relating to non-
laser optical radiation safety
1 Scope
This part of GB/T 30117 provides the basis for optical radiation safety requirements of
non-laser products, serving as a guide for development of safety requirements in
vertical product standards and assisting lamp system manufacturers in the interpretation
of safety information provided by the lamp manufacturers.
This part provides guidance on:
-- requirements for optical radiation safety assessment;
-- allocation of safety measures;
-- labelling of products.
This part does not address safety requirements of intentional exposure to optical
radiation from sun tanning equipment, ophthalmic instruments or other
medical/cosmetic devices whose specific safety issues are addressed through
appropriate standards.
2 Normative references
The following documents are essential to the application of this document. For the dated
referenced documents, only the versions with the indicated dates are applicable to this
document; for the undated referenced documents, only the latest version (including all
the amendments) is applicable to this document.
IEC 62471 Photobiological safety of lamps and lamp systems
IEC 60825-1 Safety of laser products - Part 1: Equipment classification,
requirements and user's guide
IEC 60825-2 Safety of laser products - Part 2: Safety of optical fiber

IEC 60050-845 International electrotechnical vocabulary
be reported as irradiance or spatially averaged radiance values at a distance that
produces an illuminance of 500 lx. Only lamps and lamp systems that are classified as
Exempt Group with respect to the skin hazard when assessed at the location of the 500
lx illuminance level, shall normally be used for GLS applications. In addition, if the
application requires skin access to the optical radiation from the source where the
illuminance is likely to exceed 500 lx for periods of exposure longer than 1 h, the user
shall be warned that an exposure assessment may be required.
NOTE: The above is intended to ensure that applications are considered where, for example, the UV
emission limits may be exceeded. This may be of concern for some lamps where the emission limits are
not exceeded at 500 lx, but may be exceeded at a higher illuminance level where the hands, for example,
may be located during fine detail task illumination, or where the head is closer to the source than the
surface illuminated at 500 lx.
The required illuminance measurement of the GLS lamp systems takes into account
contributions from all the elements of the lamp system. In contrast to the radiance
measurement for risk group determination, the acceptance angle for the illuminance
measurement of GLS sources is not limited. When multiple lamps or modifying optics
are applied to a GLS product, the ultraviolet and infrared emission of the product in
many cases may be reduced; thus, the corresponding risk is reduced. Furthermore, if
lenses or arrays increase the 500 lx distance, the angular subtense of the component
sources decreases (and the spatially averaged radiance decreases), so that the risk
remains essentially the same.
In cases where the classification by the lamp manufacturer is based on radiance or time-
integrated radiance and where irradiance-dependent hazards can be neglected (LEDs or
by the use of appropriate filters), the GLS-classification of the lamp can directly be
transferred to the lamp system/luminaire.
5.3.3 Multi-purpose lamps
The following general approach shall be followed in the course of risk group
determination of lamp systems. In cases where the risk classification of the lamp is
based on the most restrictive radiance or time-integrated radiance criteria, these values
remain unchanged or are decreased by integration of the lamp into a system or by
adding optical elements. Such measures or elements, in contrast, may change the
irradiance or radiant exposure produced by a source and shall be considered in cases
where the risk grouping of the incorporated lamp is based on those criteria. However,
the possible variation of the most restrictive classification criterion, i.e., from radiance
to irradiance, shall be considered in case of radiance-based classification of the
incorporated lamp.
5.3.4 Determination of the hazard distance
In order to be independent of the use condition, the risk group classification of lamps
