Scope

This document general requirements for the photobiological safety assessment, hazard
types, emission limits, risk level classification methods, labeling and safety control
measures of non-coherent light products.
This document applies to non-coherent light products with emission wavelengths
between 200 nm~3000 nm, including various lamps and lamp systems, intentional
viewing and unintentional viewing products, LED light-emitting devices, etc.
It also applies to non-coherent light products specified in GB/T 7247.1 that have similar
functions to traditional light sources but are excited by lasers, such as laser projectors,
automotive laser lighting, and other laser-excited broadband light sources. It does not
apply to general laser products specified in GB/T 7247.1.
NOTE 1.The main contents of this document are also applicable to the assessment of risks from
other sources of optical radiation that are not electrically generated, such as incandescent materials
and gas-fired space heaters.
NOTE 2.Light radiation may not be the primary function of the product; for example, the light
source in a refrigerator.
NOTE 3.Non-coherent light products are also commonly referred to as light sources, optical
radiation sources, or non-coherent light sources. They are primarily distinguished from laser
products that emit a single wavelength (very narrow bandwidth) in a directional manner and have
distinct coherent characteristics.
This document does not specify safety requirements for specific application products.
General lighting (GLS) lamps and lamp systems, ultraviolet products, and projectors
are all included in the scope of this document. Optical radiation safety standards
developed for these specific application products shall provide specific risk group
assessment criteria, risk levels, and safety control measures for each product.
Risk Classification facilitates risk assessment of products and helps determine the
control measures required by users. Its purpose is to ensure that products on the market
are as safe as possible. Products classified as Risk Category 3 are generally not suitable
for general consumer use.
The following situations may also pose optical radiation safety issues but are outside
the scope of this document.
• Distracting light;
• Glare;
• Flash blindness;
• Temporary visual impairment;
• Light flickering;
• Abnormal photosensitivity;
• Exposure to photosensitizing chemicals or medications;
• Children under three years old, or those with aphakia or artificial lenses;
• Circadian rhythm disruption caused by light radiation;
• Abnormal personal behavior, such as intentionally staring at a bright light source;
and abnormal behavior caused by alcohol or drugs.
This document applies to non-coherent light products intended for use by normal adults
with healthy eyes and skin. Furthermore, the optical radiation hazard types and
corresponding emission limits used in this document only consider short-term use.
Risks arising from long-term use, such as skin cancer caused by long-term ultraviolet
radiation exposure, are not considered in this document.
This document does not apply to electronic tanning lamps, ophthalmic instruments, or
other devices for special medical applications. The safety requirements for these
products are covered by other appropriate standards.
NOTE. In this document, adults refer to people who have received legally compulsory education
and have a certain level of knowledge, and are generally not less than 18 years old.
