Products have been optically designed according to the application and are safe in normal use; the optical radiation emitted by some products may be harmful to human health. Some products may cause adverse effects when used under abnormal circumstances, which may cause photobiological radiation hazards. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has established safe photobiological exposure limits for incoherent light. According to the photobiological safety exposure limits stipulated by ICNIRP, the light emission limits for each risk level are determined to protect people with various potential light radiation hazards. The contact status of the body is classified to provide a basis for determining the optical radiation risk level of incoherent optical products. Compared with single-wavelength laser products, the assessment and risk control of optical radiation hazards of incoherent optical products are more complicated, involving The measurement of radiation is also difficult because it may measure a wide-spectrum, spatially extended surface light source, not a simple point light source; Moreover, the light beam may be changed by other diffusers or optical lenses in the product, and the spectral distribution may also be affected by related optical filters, diffusers, etc. The radiation results should be considered comprehensively. To evaluate an incoherent light product, such as an arc lamp, incandescent lamp, fluorescent lamp, LED lamp, or other lamp system, first, you need to determine The spectral distribution of light radiation reaching the human eye and skin. For the optical radiation system, due to the filtering of the optical devices in the light path, the beam changes (such as projection lens), etc. The spectral distribution of light radiation received by the human body may be different from the spectral distribution of the light emitted by the lamp itself. The hazard is related to the light source's luminous area or the apparent source after being imaged by the projection lens. Finally, the actual effective irradiance or radiance is related to the observed In addition, different viewing behaviors will produce different results; for example, lighting products for general lighting applications, whether intentional or not In the viewing state, the light source is imaged on the retina only occasionally during the 8-hour working day, and it is different from intentional viewing. Therefore, when determining the optical radiation risk level of incoherent optical products, it is necessary to consider the light source itself. The light emission state of the human body, the differences in potential hazards of different tissues in the human body, and the expected contact state.

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 Optical radiation may not be the primary function of a product; for example, a light source in a refrigerator. Note 3.Incoherent optical products are also commonly called light sources, optical radiation sources or incoherent light sources; they are mainly distinguished from directional emission of a single wavelength (very narrow bandwidth) and Laser products with obvious coherent characteristics. This document does not specify safety requirements for products for specific applications. General lighting (GLS) lamps and lamp systems, UV products and projectors The optical radiation safety standards developed for these specific application products will provide specific risk factors for specific products. Requirements for risk group assessment conditions, risk levels and safety control measures. Risk classification will assist in the risk assessment of the product and help determine the control measures required by the user. The products on the market are safe. Products in risk category 3 are usually not suitable for general consumption. 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 photosensitive chemicals or consumption of photosensitive drugs; ● Children under three years old, eyes with aphakia or eyes with artificial lenses; ● Circadian rhythm disruption caused by light radiation; ● Abnormal personal behavior, such as deliberately staring at a strong light source; abnormal behavior caused by alcohol or drugs. This document is applicable to incoherent optical products that are exposed to normal adults, people with healthy eyes and skin conditions. The radiation hazard types and corresponding emission limits only consider short-term use; for the risks that may arise from long-term use, such as long-term ultraviolet Possible skin cancer caused by radiation is not considered within the scope of this document. This document does not apply to electronic tanning lamps, ophthalmic instruments, or other equipment for special medical applications. The safety requirements of these products are determined by other He has corresponding standard provisions. 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.2 Normative referencesThe contents of the following documents constitute the essential clauses of this document through normative references in this document. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 30117.1-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 30117.1-2024_English as soon as possible, and keep you informed of the progress.
