Talabalar uchun ko'zni himoya qilish uchun stol chiroqida nima bo'lishi kerak?
Bugun biz ko'zni himoya qilish uchun stol chiroqlari haqida bilib olamiz. Odamlar ibtidoiy jamiyat evolyutsiyasi davrida tabiiy yorug'likka moslashganligi sababli, ko'zni himoya qilish uchun stol chiroqi tabiiy yorug'likka qanchalik yaqin bo'lsa, ko'zni himoya qilish shunchalik samarali bo'ladi.
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 ob'ekt rangini tabiiy yorug'likda haqiqatan ham tiklashi mumkin. Hatto yorug'likda ham, to'q ko'k va qora o'rtasidagi farqni ajratib ko'rsatish kerak, bu o'quvchilarga yanada real ranglarni ko'rish imkonini beradi.
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.
Yuqoridagi tavsifga asoslanib, biz ko'zni himoya qiladigan stol chiroqining nima ekanligini bilishimiz kerak.
Ko'zni himoya qiladigan stol lampalaridan xavfsiz foydalanish odatda quyidagi fikrlarga ega:
1. Kam porlashli dizayn;
2. Milliy AA darajasidagi yoritish standartiga rioya qiling;
3. Elektr ta'minotini miltillashsiz qabul qiling va EMC va EMI sertifikatidan o'tdi
4. Spektr tabiiy yorug'likka yaqin bo'lishi kerak va stol chiroqi quyosh nurlari spektriga qanchalik yaqin bo'lsa, ko'zni himoya qilish shunchalik yaxshi bo'ladi.
