Beth ddylai fod gan y lamp desg amddiffyn llygaid ar gyfer myfyrwyr?
Heddiw rydyn ni'n mynd i ddysgu am y lamp desg amddiffyn llygaid. Gan fod bodau dynol wedi addasu i olau naturiol yn ystod esblygiad cymdeithas gyntefig, po agosaf yw'r lamp desg amddiffyn llygaid i olau naturiol, y mwyaf effeithiol yw amddiffyn y llygaid.
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>Gall 95 wirioneddol adfer lliw y gwrthrych mewn golau naturiol. Hyd yn oed mewn golau, dylid gwahaniaethu rhwng glas tywyll a du er mwyn galluogi myfyrwyr i weld lliwiau mwy realistig.
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.
Yn seiliedig ar y disgrifiad uchod, mae angen inni wybod beth sydd gan y lamp bwrdd amddiffyn llygaid.
Yn gyffredinol, mae gan y defnydd diogel o lampau bwrdd amddiffyn llygaid y pwyntiau canlynol:
1. Dyluniad llacharedd isel;
2. Cydymffurfio â'r safon goleuo lefel AA genedlaethol;
3. Mabwysiadu'r cyflenwad pŵer heb unrhyw fflachiad a phasio ardystiad EMC ac EMI
4. Dylai'r sbectrwm fod yn agos at olau naturiol, a pho agosaf yw'r lamp bwrdd i sbectrwm golau'r haul, y gorau yw'r amddiffyniad llygad.
