Kuwopsa kwa kuyatsa kwamagetsi

Chiyambireni kuunikira m'nthawi ya nyali za fulorosenti, nyali zoyatsidwa ndi magetsi zakhala zikusefukira m'malo athu.Kutengera mfundo yowala ya nyali za fulorosenti, vuto la kufinya silinathedwe bwino.Masiku ano, talowa m'nthawi ya kuyatsa kwa LED, koma vuto la kuwala kowala likadalipo.

Kodi flicker ndi chiyani

Flicker ndi kusintha kwa mphamvu ya kuwala kapena kuwala mu nthawi inayake.Kuwala kounikira kumachitika m'njira zambiri zowunikira, kuphatikiza kuwombera pang'onopang'ono pa TV, kuyatsa misewu, magawo osiyanasiyana owunikira komanso malo antchito pogwiritsa ntchito makina ozungulira mwachangu.Flicker idzakhudza thanzi la munthu, ndipo kuchuluka kwa momwe zimakhudzira zimatengera kuchuluka kwa kuthwanima komanso kukhudzika kwamunthu kuti ayende.Kuthamanga kwafupipafupi sikudzakhudza kwambiri thupi la munthu, koma kutsika kwafupipafupi pansi pa 120 Hz ndikosavuta kukhudza thanzi la munthu.

Kulemera kwa diso la munthu kukhudzika ndi kugwedezeka

Kuwopsa kwa kuyatsa kwamagetsi

Kuwala kochokera ku kuwala kumagwirizana kwambiri ndi mutu waching'alang'ala, mutu, autism, kutopa kwa maso, kusawona bwino ndi matenda ena a ubongo.Kafukufuku wasonyeza kuti otsika pafupipafupi, osiyanasiyana 3-70Hz scintillation gwero kuwala kungayambitse photosensitive khunyu kwa anthu ena tcheru;100Hz flicker frequency adadziwika kuti amayambitsa mutu ndi migraine;Gwero lounikira la 120Hz limatha kukhudza momwe anthu amakhalira, monga kutopa komanso nkhawa.Chinyengo chowoneka choyambitsidwa ndi mawonekedwe a flicker komanso kusuntha kwamakina ndikowopsa kwambiri m'malo ogulitsa.Chifukwa chake, kuyeza ndikuwunika molondola mawonekedwe a zinthu zowunikira ndizogwirizana mwachindunji ndi thanzi la anthu, lomwe ndi vuto lachangu lomwe likuyenera kuthetsedwa.

Zifukwa za flicker

Zifukwa za kufiyira kwa nyali za LED sizimaphatikizapo zinthu zokha za magetsi, komanso zomwe zimapangidwira luso la gwero la kuwala ndi kapangidwe kake kopanda nzeru.Kuthamanga kwamagetsi ndi chimodzi mwazinthu zofunika zomwe zimachititsa kuti magetsi aziyendera magetsi ambiri.Ripple current ndi gawo la AC lomwe likadalipo pambuyo pokonzanso ndikusefa.Ma Ripple current ali pamwamba pa DC ndipo ali ndi ma frequency ndi ma curve osiyanasiyana.Chigawo cha AC ichi chimapangitsa mphamvu ya module ya LED kusinthasintha, zomwe zidzasintha kuwala.Kuchuluka ndi kuchuluka kwa ma AC apamwamba kwambiri ndizomwe zimapangitsa kuti pakhale kunjenjemera.

Chithunzi chofotokozera za flicker index ndi kuchuluka kwa flicker

Momwe mungachotsere flicker

Kuphatikiza pa ntchito yochotsa mdima ndi kuunikira chilengedwe, kuyatsa kuyenera kuganizira za thanzi la zinthu.Kupanda chiwopsezo kwa anthu ndi gawo la magwiridwe antchito a nyali zomwe siziyenera kunyalanyazidwa.

Kukhudzidwa ndi kukonzedwanso kwa voteji yamagetsi (50Hz mu muyezo waku Europe), ma frequency a ripple current mu gawo lalikulu la ma drive a LED amawirikiza kawiri mphamvu yamagetsi, yomwe ili pafupifupi 100Hz.Kuphatikiza apo, poyerekeza ndi magwero anthawi zonse, ma LED amatha kusintha nthawi yomweyo kuwala komwe kumagwira ntchito.Kuti mukwaniritse kutulutsa kowala popanda kugwedezeka momwe mungathere, dalaivala wapamwamba kwambiri wa LED komanso kuyanjana pakati pa dalaivala, dimmer ndi gawo la LED ndizofunikira kwambiri.Chithunzi chotsatirachi ndi njira yodziwika bwino yowunikira chida chowongolera kudzera pa "output current ripple" kapena "superimposed AC".Nthawi zambiri, mtengo wowonetsedwa ndi 100Hz.Kutsika mtengo, m'pamenenso chiopsezo cha flicker chimachepetsa.

Zithunzi Zovomerezeka za IEEE Zosintha Ma LED Amakono Owala Kwambiri Pochepetsa Zowopsa Zaumoyo kwa Owonera

Nyali za Wellway za LED ndi zounikira, kaya zosawotchera madzi, nyali za bulaketi, mapanelo ndi nyali zosagwira fumbi, kuphatikiza zitsanzo zoyambira ndi zitsanzo zozindikira mwadzidzidzi, onse amazindikira ntchitoyi popanda kuthwanima.Mphamvu zapamwamba zomwe zimagwiritsidwa ntchito ndi nyali zimatha kuchepetsa kutulutsa kwamphamvu ndikuzindikira kufananiza koyenera ndi zigawo za nyali.

(Zithunzi zina zimachokera pa intaneti. Ngati pali zophwanya, chonde titumizireni ndikuzichotsa nthawi yomweyo)
