What should the eye protection desk lamp for students have?
Today we are going to learn about the eye protection desk lamp. Since humans have adapted to natural light during the evolution of primitive society, the closer the eye protection desk lamp is to natural light, the more effective it is to protect the eyes.
But we all know that desk lamps are usually used at night, and cold light can help students/overtime dogs concentrate and increase their motivation level. Whenever cold light affects the secretion of melatonin, it will affect the quality of sleep. Take the eye protection desk lamp as an example. Yellow light can help you sleep, but most parents don't want students to be drowsy during homework. 4000K is the color temperature of the same student desk lamp that takes into account both health and learning power. The color rendering of student desk lamps is equal to 95RA, and almost more than 90RA. The color rendering index Ra>95 can truly restore the color of the object in natural light. Even in light, the difference between dark blue and black should be distinguished to allow students to see more realistic colors.
Use the high color rendering LED light source produced by the regular manufacturer BENWEI LIGHTING, and control the color temperature not to be greater than 6000K, so don't worry about blue light. The lower the color temperature, the lower the blue light ratio; the blue light ratio of the LED light source produced by the full-spectrum violet excitation technology is lower than that of the blue light excited LED light source. The working color temperature of the student desk lamp is recommended to be 3600-4000K. In case the students are prone to sleepiness, the color temperature of 4000-5000K can be selected.
Based on the above description, we need to know what the eye protection table lamp has.
The safe use of eye protection table lamps generally have the following points:
1. Low glare design;
2. Comply with the national AA level illumination standard;
3. Adopt the power supply with no flicker and passed EMC and EMI certification
4. The spectrum should be close to natural light, and the closer the table lamp to the sunlight spectrum, the better the eye protection.
