Kuunikira kumagwira ntchito yofunika kwambiri m'malo onse omanga. Ntchito yake yayikulu imatithandiza kuwona, komanso zimakhudza kwambiri kukongola ndi mawonekedwe.
Ichi ndichifukwa chake kutentha kwa mtundu wa kuyatsa kwanu ndikofunikira. Ndi mtundu wanji wa ambiance womwe mukufuna kuti malo anu azikhala nawo? Kodi mukufuna kuti nyumbayo iwoneke yofunda ndi yolandirika kapena yozizira komanso yofunda? Komanso, ndi mtundu wanji wa CCT womwe ungakuthandizeni kukwaniritsa zomwe mukufuna?
Nkhaniyi ikuthandizani kusankha CCT yolondola ya kuwala kwanu kwa LED.
Kutentha kwamtundu ndi kotani?
Kutentha kwamtundu ndi gawo la kuyeza komwe kumasonyeza chigawo cha mtundu chomwe chili ndi kuwala. Mwachidziwitso, kutentha kwa thupi lakuda kumatanthawuza mtundu wa munthu wakuda wakuda utatenthedwa kuchokera ku ziro (-273 ° C). Akatenthedwa, thupi lakuda limasintha pang’onopang’ono kuchoka pakuda kukhala lofiira, limasanduka lachikasu, limawala, ndipo pomalizira pake limatulutsa kuwala kwa buluu. Akatenthedwa ndi kutentha kwapadera, mawonekedwe owoneka bwino a kuwala kotulutsidwa ndi thupi lakuda amatchedwa kutentha kwa mtundu. Pa kutentha kumeneku, muyeso woyezera ndi “K” (Kelvin).
Kutsika kwa kutentha kwa mtundu, kumapangitsanso kutentha kwa mtundu wowala. Kukwera kwa kutentha kwamtundu, kumapangitsa kuti utoto wowala ukhale wozizira.
Masana, kutentha kwa masana kumasintha nthawi zonse, kuchokera ku 2000K kutuluka kwa dzuwa ndi kulowa kwa dzuwa kufika pa 5500-6500K masana.
Kutentha kwamtundu ndi muyeso womwe umagwiritsidwa ntchito pofotokoza mtundu wowala pa malo a Planckian komanso opangidwa ndi radiator ya Planckian. Iyi ndi metric yocheperako, chifukwa imagwira ntchito pamtundu wa kuwala kuchokera ku ma radiator a Planck. Chigawo chilichonse cha kutentha kwamtundu chimakhala ndi ma chromaticity coordinates mu danga lamtundu womwe wapatsidwa, ndipo ma coordinates ali pa Planckian locus.
Correlated color temperature(CCT) ndi muyeso womwe umagwiritsidwa ntchito pofotokoza mtundu wa kuwala womwe uli pafupi ndi malo a Planck. Metric iyi imagwira ntchito mokulirapo chifukwa imagwira ntchito pamagwero osiyanasiyana owunikira, iliyonse imapanga kugawa kwamagetsi kosiyana ndi kwa radiator ya Planck. Komabe, sizolondola ngati kuchuluka kwa kutentha kwa mtundu chifukwa mfundo zambiri pazithunzi za chromaticity pamodzi ndi isotherm zimakhala ndi kutentha kwamtundu womwewo.
Chifukwa chake, makampani owunikira amagwiritsa ntchito kutentha kwamtundu wolumikizana (CCT).
Zomwe muyenera kuziganizira posankha CCT?
CCT imatha kukhudza momwe anthu amamvera, choncho ndikofunikira kusankha CCT yoyenera. Nazi zina zomwe ziyenera kuganiziridwa posankha CCT.
kuwala
Kuwala kumakhudzanso mmene munthu akumvera.
CCT VS Lumens
Lumen ndi kufotokozera momwe kuwala kulili kowala.
CCT imalongosola mtundu wa gwero la kuwala. M'munsi mwa CCT, kuwala kwachikasu kumawoneka; kumtunda kwa CCT, kuwala kwa buluu kumawoneka. Palibe mgwirizano wachindunji pakati pa CCT ndi kuwala.
Kodi CCT imakhudza lumens?
Ma lumens apamwamba a CCT adzakhalanso apamwamba pamtundu womwewo wa LED.
Chifukwa chachikulu ndikuti maso aumunthu amakhudzidwa kwambiri ndi kuwala kwa CCT yapamwamba ndikumva kuwala.
Chifukwa chake posankha chingwe chotsika cha CCT LED, muyenera kuwonetsetsa kuti ma lumens akukwanirani.
Zotsatira za CCT pamalingaliro amunthu
Kutentha kwamtundu kumakhudza kwambiri malingaliro amunthu. Kuwala koyera kotentha kumapangitsa anthu kukhala ofunda komanso omasuka. Mosiyana ndi zimenezi, kuwala koyera kozizira kumapangitsa anthu kudzimva kukhala okhwima, ovuta, komanso otsika.
CCT yosinthika
Mukuganizanso, kodi pali mtundu wa CCT yowunikira ya LED yomwe ingasinthidwe malinga ndi zosowa zanu? Inde, athu Mzere wa LED wosinthika wa CCT imatha kukwaniritsa zosowa zanu.
Mutha kulumikiza chingwe chosinthika cha CCT LED kwa wowongolera ndikusankha CCT yomwe mukufuna kudzera mwa wowongolera.
Momwe mungasankhire CCT yoyenera?
The kwambiri ntchito mtundu kutentha ndi 2700K, 3000K, 4000K, ndi 6500K. Kutentha kwamtundu wanji kumadalira komwe tikufuna kuzigwiritsa ntchito komanso mtundu wa mlengalenga womwe tikufuna kupanga.
Ndi liti pamene mungasankhe 2700K yowonjezera yoyera?
Magetsi owonjezera otentha a 2700K LED ali ndi kuwala kofewa, kwapafupi, kotentha koyera komwe timapangira muzipinda zochezera ndi zogona. Kuwala koyera kotentha kumawonedwanso kukhala kothandiza kumasuka. Mungafunike kuwala kotentha kuti mukonzekere kugona, chifukwa kuwala kwa buluu kumatha kupondereza mahomoni a melatonin omwe thupi limatulutsa mwachibadwa kuti mugone. Pazamalonda, kuwala kotentha kumapangitsa kuti pakhale malo odekha, aumwini, apanyumba m'malesitilanti, mahotela, ndi malo ogulitsira.
Ndi liti pamene mungasankhe 3000K yoyera yotentha?
Poyerekeza ndi 2700K, 3000K imawoneka yoyera.
Timalimbikitsa kugwiritsa ntchito kuyatsa koyera kwa 3000K m'khitchini ndi m'bafa.
Poyerekeza ndi 2700K, kuwala kotentha kwa 3000K kumapangitsa kuti pakhale mpumulo, koma malo ozungulira amakhala olondola komanso oyenera malo okhala komwe nthawi zambiri mumagwira ntchito. Kuwala kotentha kwa 3000K kumapangitsa kuti pakhale malo omasuka, okhala kunyumba kwa bizinesi m'zipinda za alendo, malo odyera, ndi malo ogulitsa zovala.
Ndi liti pamene mungasankhe 4000K yoyera?
White 4000K ili ndi kuwala koyera, kolunjika, kosalowerera ndale komwe kumakwanira bwino m'maenje, magalaja, ndi makhitchini. Poyerekeza ndi kuunikira kofunda, zoyera zopanda ndale zimakumasulani ndikukulolani kuti muyang'ane chidwi chanu. Pazamalonda, izi ndizabwino ku maofesi, malo ogulitsa zakudya, zipatala, makalasi, ndi malo ogulitsira zodzikongoletsera, makamaka omwe amagulitsa diamondi kapena siliva.
Ndi liti pamene mungasankhe 6500K yoyera yoyera?
White 6500K imayamikiridwa m'malo antchito omwe amafunikira chidwi komanso magwiridwe antchito. Malowa akhoza kukhala ma laboratories, mafakitale, ndi zipatala. Ntchito ina yofunika kwambiri ndi ulimi, makamaka munda wamkati.
Chifukwa chiyani kuwala komweko kwa CCT LED kumawoneka kosiyana?
Mutha kukumana ndi vuto kuti magetsi a CCT LED omwewo, koma mitundu imawoneka yosiyana. Chifukwa chiyani vutoli likuchitika?
zida mayeso
Makina omwe amayesa CCT amatchedwanso gawo lophatikiza. Pali mitundu yambiri ndi mitundu yophatikiza magawo, ndipo onse ali ndi zolondola zosiyanasiyana. Choncho, magetsi a LED ochokera kwa opanga osiyanasiyana adzakhala ndi mitundu yosiyanasiyana ya CCT yomweyi ngati akugwiritsa ntchito magawo osiyanasiyana ophatikizana.
Gawo lophatikizana liyenera kusinthidwa mwezi uliwonse. Ngati gawo lophatikizira silinawerengedwe pa nthawi yake, zoyesererazo zidzakhalanso zolakwika.
Kulekerera kwa CCT
Ngakhale magetsi a LED amalembedwa ndi 3000K, sizikutanthauza kuti CCT yeniyeni ndi 3000K. Opanga osiyanasiyana ali ndi kuthekera kosiyana kwa CCT kulolerana ndi kuwongolera, kotero nyali za LED zolembedwa ndi CCT yomweyo zitha kukhala ndi CCT ina yeniyeni. Opanga abwino amagwiritsa ntchito miyezo yololera mitundu mkati mwa masitepe atatu a macadam pakufananitsa mitundu.
Duv
Malinga ndi tanthawuzo la CCT, kuwala kwa CCT komweko kungakhale ndi makonzedwe amitundu yosiyanasiyana. Mtundu udzakhala wofiira ngati mfundo yogwirizanitsa ili pamwamba pa phiri la blackbody. Pansi pa mapindikidwe amtundu wakuda, idzakhala yobiriwira. Duv ndi kufotokoza khalidwe ili la kuwala. Duv amafotokoza mtunda wa malo olumikizira kuwala kuchokera pamapindikira amtundu wakuda. Duv yabwino imatanthawuza kuti malo ogwirizanitsa ali pamwamba pa poto wakuda. Pomwe choyipa chimatanthawuza kuti chili pansi pa piritsi la blackbody. Kukula kwa mtengo wa Duv, kumakhalanso patali kuchokera pamapindikira amtundu wakuda.
Kotero, CCT ndi yofanana, koma Duv ndi yosiyana; mtundu wa kuwala udzawoneka mosiyana.
Kuti mudziwe zambiri za Duv, chonde onani Pano.
Kutsiliza
Kwa polojekiti yowunikira kwambiri, kusankha CCT yoyenera ndikofunikira. Pamene ntchito yowunikira imagwiritsa ntchito mitundu ingapo ya nyali za LED, kufananitsa mitundu yosiyanasiyana ya nyali za LED zokhala ndi mtundu womwewo kungakhale kovuta, ngakhale mitundu yosiyanasiyana ya nyali za LED izi zili ndi CCT yodziwika bwino.
LEDYi ndi katswiri Mzere wa LED wopanga, ndipo timayika mikanda ya LED tokha. Timapereka ntchito zamaluso zofananira mitundu ndi CCT yokhazikika kwa makasitomala athu.
