In the context of increasing attention to the quality of lighting products, and issues such as blue light hazards and stroboscopic flickering have become social hotspots, do LED lamp beads pose a safety hazard to the visual health of children during development?
Whether it is LED lamp beads or traditional light sources, when used in classroom lighting, the corresponding parameters should meet the requirements of the lighting standards for various indicators.
Due to the development and gradual popularization of LED lamp bead lighting products, there is a need for classroom lighting LED lamp bead standards. At present, the China Quality Certification Center (CQC) has issued the "Technical Specification for Energy-saving Certification of Classroom Lighting Products in Primary, Secondary, and Kindergarten" in 2016 , The LED lamp beads product parameters have been further regulated, and other standards for LED classroom lighting have yet to be improved.
Whether there is a hidden safety hazard in LED lamp beads At present, the luminous efficiency and lamp efficiency of white LED lamp beads for general lighting have exceeded traditional light sources, and can achieve high color rendering and high stability, which can meet the needs of smart lighting for dimming. The key to the use of LED lamp beads depends on whether the final luminaire can meet the requirements of lighting indicators and related lighting devices.
Regarding the photobiological safety of LED lamp beads, you can refer to the "General Lighting LED and Blue Light" white paper jointly issued by the International Semiconductor Lighting Alliance, the National Semiconductor Lighting Engineering R&D and Industry Alliance and the China Illuminating Society in July 2013. The white paper clearly mentions that the correct use of qualified general lighting white LED lamp beads is completely safe for human eyes.
What should I pay attention to when using LED lamp beads in the classroom?
At present, the use of LED lighting in school classrooms has problems such as disordered branding, uneven quality, irregular market, lack of regular maintenance, and unsound standards. However, the problems cannot be attributed to the LED lamp beads themselves.
The following issues should be paid attention to when using LED products in classroom lighting:
1. The selection of LED lamp beads should meet the specification requirements in terms of light color quality and other quality, including meeting safety level requirements, performance requirements, reliability requirements, environmental protection regulations, etc.;
2. The light source and lighting system should be used correctly, including the use of reasonable lighting design, correct installation methods, regular inspection and maintenance, etc.;
3. For all kinds of light sources and lighting system products, photobiological safety tests should be carried out. Even if they are safe based on standards and require no additional warning signs, users should still avoid looking directly at these light sources for a long time. Especially in the case of shorter distances.
