LED's are used in class lighting.

LEDs are used in class lighting.

At present, there are two main conflicts about "can use the LED light source in the classroom lighting at this stage".

1) In the rapid development of LED technology, LED lamps are gradually replacing the main Clarinda rare earth trichromatic fluorescent lamps “used in class lighting. Does it allow and recommend the use of existing national standard LED light sources for class lighting?

2) Blu-ray hazards in the context of the quality of increased lighting products, stroboscopic and other issues have become a hot topic in the community. Are there potential safety hazards for the visual health of children during the development of the LED light source?

LED light source has safety hazards

At present, the effectiveness of white LEDs for general lighting and armature efficiency can achieve higher and higher color reproduction and higher stability than traditional light sources and can meet the demand for smart lighting to be reduced. The key to the use of LEDs depends on whether the final luminaire meets the lighting specifications and the relevant lighting conditions.

Please refer to the "General Lighting LED and Blu-ray" white paper, jointly published by the International Semiconductor Lighting Alliance, the National Semiconductor Lighting Engineering R & D, and Industrial Alliance and the China Lighting Society, in July 2013 for the LED's photo bio cognition problem. The correct use of qualified general purpose white LED products on white paper is clearly stated to be completely safe for the human eye.

LED Lamp in Class Room

At the moment, the public has many concerns about Blu-ray, but we can't neglect it for Blu-ray.

On the one hand, blue light is an important component of white light; it plays an important role not only in creating color but also in the circadian rhythm. The outer daylight can perform the function of synchronizing the circadian rhythm of the human body (or circadian clock) synchronously, and the exposure of the blue light to the interior is much less than the dose taken by outdoor activities. Blue and cool white light sources can be used to create a suitable light environment to help people receive the daily dose of blue light to allow circadian rhythms to be coordinated with the natural circadian rhythm.

On the other hand, the -5 blue light hazard fade that we usually hear refers to the light band's 400-500 nm blue light band. If the brightness is too high, the eye may cause photochemical damage to the retina after a long time direct viewing of the light source. The blue light problem is basically a combination of brightness, blue light weighting function and time. From a spectral point of view
