Apa yang harus dimiliki lampu meja pelindung mata untuk siswa?
Hari ini kita akan belajar tentang lampu meja pelindung mata. Karena manusia telah beradaptasi dengan cahaya alami selama evolusi masyarakat primitif, semakin dekat lampu meja pelindung mata dengan cahaya alami, semakin efektif untuk melindungi mata.
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 benar-benar dapat mengembalikan warna objek dalam cahaya alami. Bahkan dalam cahaya, perbedaan antara biru tua dan hitam harus dibedakan untuk memungkinkan siswa melihat warna yang lebih realistis.
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.
Berdasarkan uraian di atas, kita perlu mengetahui apa saja yang dimiliki lampu meja pelindung mata.
Penggunaan lampu meja pelindung mata yang aman umumnya memiliki poin-poin berikut:
1. Desain silau rendah;
2. Memenuhi standar penerangan tingkat AA nasional;
3. Mengadopsi catu daya tanpa flicker dan lulus sertifikasi EMC dan EMI
4. Spektrum harus dekat dengan cahaya alami, dan semakin dekat lampu meja dengan spektrum sinar matahari, semakin baik perlindungan mata.
