Ki pi bon, dirije lanp biwo oswa lanp pwoteksyon je?
Why are there so few lamps in our daily life and learning? There are many people who use LED desk lamps and eye protection lamps, but I don't know which is better. The following eye protection lamp manufacturers will help you. For comparison, please read carefully.
Which is better, led desk lamp or eye protection lamp? Let's introduce them separately;
Lanp dirije biwo a gen bon direksyon epi li ka eklere sou demann. Li apwopriye kòm yon lanp biwo ijans. Lanp dirije biwo a adopte ekipman pou pouvwa DC, pa gen okenn stroboskopik, pa gen okenn radyasyon elektwomayetik, pwoteksyon anviwònman vèt, efikasite segondè ak ekonomize enèji. Anplis de sa, pèl yo lanp dirije gen yon lavi ki pi long. Anplis de sa, pi long lan lanp dirije biwo a limen, pi vit fosfò a nan sous la pouri limyè, ak kòm yon rezilta, limyè a nan gwoup la limyè ble ki kontak je imen an ap vin pi fò ak pi fò, kidonk sa ki lakòz domaj nan la. je moun. Se poutèt sa, lè je yo gade sous la limyè ki ap dirije pou yon tan long, li fasil fè moun santi tèt vire ak alèz, e menm lakòz domaj nan je, ki pral ogmante pwobabilite pou maladi je. Rapèl, pa kite je ou fikse nan sous limyè ki ap dirije klere pou yon tan long pou evite domaj nan je.
Let's talk about the eye protection lamp. The eye protection lamp uses a variable frequency electronic ballast to increase the electrical frequency from 50Hz to 30-50kHz, and the change in the brightness of the light becomes very small due to the afterglow effect of the phosphor, so the human eye There is basically no stroboscopic feeling, and the light uses tri-color phosphors to make the light soft, so as to reduce visual fatigue. The eye protection lamp first converts alternating current into direct current, and uses direct current to light the lamp, which also achieves basically no stroboscopic, which can avoid visual fatigue and has no electromagnetic interference.
Pi wo a se yon rezime detaye sou lanp ki ap dirije tab la ak lanp pwoteksyon je ki fèt pa manifakti lanp pwoteksyon je. Kòm pou youn ki pi bon, tout moun gen repons lan. Sepandan, editè a rekòmande pou ou sèvi ak lanp pwoteksyon je pou rezon ki endike anwo a. Kounye a, elèv yo anba anpil presyon pou yo etidye. Paran yo ka sèlman ede pitit yo achte yon lanp pwoteksyon je. Si ou vle konnen ki jan yo chwazi yon lanp pwoteksyon je elèv, editè a ap ba ou yon entwodiksyon detaye nan pwochen konferans lan sou founiti elèv yo. Tanpri peye atansyon.
