As a solid semiconductor light source, LED lamp beads have continued to improve in recent years and the price has continued to decline. Compared with traditional light sources, LED lamp beads have many advantages such as small volume, adjustable control, and long life. LED lamp beads have received rapid development and widespread attention in many application fields such as classroom lighting. At present, public opinion has many concerns about Blu -ray, but we cannot blindly deny Blu -ray.

First, Blu -ray is an important component of white light, which not only has an important role in ensuring color rendering, but also regulates physiological rhythm. Outdoor sunlight can meet the function of synchronizing the physiological rhythm (or biological clock) of the human physiological rhythm. The blue light received indoor is far less than the dose received by outdoor activities. Blu -ray and cold white light sources can be used to establish a suitable light environment to help people get the daily dose of Blu -ray to ensure the coordination of their physiological rhythms and natural day and night rhythm.

On the other hand, the "blue light harm" we hear usually refers to the 400-500nm Blu -ray band of the light source if the radiation is too high, and the eyes may cause the optical chemical damage of the retina after the eyes look directly at the light source. The blue light problem is essentially the combined function of radiation, blue light weighted function and time. From the perspective of the spectrum, the blue light ratio of the LED lamp spectrum when the color temperature rises is increased, but it is not special compared to the blue light of the fluorescent lamp spectrum. When the color temperature is the same, the blue light safety brightness of the LED lamp beads is similar to the fluorescent lamp.

There is a unified rating specification for Blu-ray retinopasus hazards at home and abroad. LED lamps with daily ordinary lighting belong to level 0 or 1 and belong to the category of safety.

Today, we mainly discuss the issue of "whether classroom lighting can use LED light sources" that currently caused discussions and doubts in society. It aims to discriminate and distinguish the concepts, and convey the correct understanding of relevant issues to people.

Second, the quality of lighting products has attracted increasing attention, and issues such as blue light hazards and frequent flashing have become hot spots in social. Is there any hidden safety hazard in vision health during development during development?

Whether it is LED lamp beads or traditional light sources, the corresponding parameters should meet the requirements of the lighting standards for various indicators when used for classroom lighting.

Due to the development and gradual popularization of LED lamp bead lighting products, the standard for classroom lighting LED lamp beads is needed. At present, the China Quality Certification Center (CQC) has released the "Technical Specifications for Energy -Saving Authentication for Lighting Products for Lighting Products in Primary and Middle Schools and Kindergarten Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Classroom Lighting Products. The LED lamp bead product parameters have been further regulated, and other standards for LED classroom lighting fixtures need to be improved.

Whether the LED lamp beads have hidden safety hazards, the light efficiency and lamp efficiency of white -light LED lamp beads used in ordinary lighting have exceeded the traditional light source, and it can achieve high color rendering and high stability, and meet the demand for smart lighting for lighting. The key to the use of LED lamp beads depends on whether the lamp can meet the requirements of lighting indicators and related lighting devices.

Regarding the optical safety issues of LED lamp beads, you can refer to the International Semiconductor Lighting Alliance, the National Semiconductor Lighting Engineering R & D and Industrial Alliance and the China Lighting Society in July 2013 "Ordinary Lighting LED and Blu -ray". The white paper clearly mentioned that the correct use of qualified ordinary photos to understand the light LED lamp products is completely safe for human eyes.
