Njengomntu wangaphandle, ingaba wazi kangakanani naisibaneumthombo wokukhanya?
Ndiyakholelwa ukuba uqhelene kakhulu nesihloko esithi "indlela yokukhetha umthombo wokukhanya wangaphandle".Ngapha koko, bonke bangabantu bangaphandle.Banamava amaninzi ekuthengeni iitoti.Ngokuhamba kwexesha, banemigangatho yabo yemigangatho: iinkonkxa zangaphandle kufuneka ziqaqambe, zikhanyise, zinyamezeleke ngamandla, zikhuselwe kathathu, iinketho ezininzi zokukhanya, kunye nokutshaja ngokuthe ngqo kwe-USB kokona kulungileyo.
Ukukhanya, ukunyamezela, ubunzima, ukuxhathisa ukuwa kunye nokuphatheka kwezona zinto zicacileyo kunye nezaziwayo ze-flashlight yangaphandle.Ke ngoko, zikwayingqwalasela yokuqala kubasebenzisi abaninzi xa kuthengwa.Ziyafuneka nje.Namhlanje, makhe sithethe ngezinto ezibalulekileyo kodwa ezingaziwayo kangako zetotshi yangaphandle, njenge-CRI, ukukhanya kombala kunye nobushushu bombala.
Malunga ne-CRI
I-CRI sisishunqulelo se-English color rendering index, nto leyo ethetha ukuba umbala wonikezelo lwesalathiso ngesiTshayina.Idigri yonikezelo yombala wokwenyani wento ngomthombo wokukhanya iba lunikezelo lombala lomthombo wokukhanya.I-CRI lubungakanani bonikezelo lombala.Isalathiso sombala wonikezelo lomthombo wokukhanya osemgangathweni (ofana nokukhanya kwelanga) uchazwa njenge-100, kwaye isalathiso sombala seminye imithombo yokukhanya singaphantsi kwe-100 Okukhona unikezelo lombala luphezulu, kokukhona isalathiso sombala sisondela kwi-100, kokukhona unamandla. ikhono lokubuyisela umbala wento, kwaye kulula ukuba iliso lomntu likwazi ukwahlula umbala wento, ngoko imvakalelo ebonakalayo ingcono.
Ngaphandle, ukukhanya okuphezulu kwesibane kunokugweba inkcazo yento, kodwa iinkcukacha kunye namanqanaba kufuneka zixhaswe ngokunikezelwa kombala okulungileyo.Oko kukuthi, ukuba ufuna ukubona ulwandlalo lwento, kufuneka ujonge kuphela isalathisi sokukhanya.Nokuba ngumthombo wokukhanya oshushu onombala we-100 okanye ukukhanya oku-monochromatic ngaphandle konikezelo lombala, ukuqaqamba kuyafana.Ukuba sifuna ukugweba umbala, iinkcukacha kunye nomphakamo wento, umbala we-75 obonisa umthombo wokukhanya ufuna ukuqaqamba okungaphezulu ukuphumeza isiphumo seenkcukacha zombala we-100 womthombo wokukhanya.
Ngoko ke ziziphi iingenelo zemithombo yokukhanya enikezela ngombala ophezulu?Ngokucacileyo, okokuqala, vumela abantu babone izinto ngokucacileyo, nto leyo iluncedo ngakumbi ngaphandle.Ngenxa yokuba awukwazi ukubona ngokucacileyo ngokwaneleyo, ngamanye amaxesha ayisiyongxaki kuphela yokungaboni kakuhle, kodwa inokukhokelela kwingozi.Umzekelo, kuba ungaboni kakuhle, udibana nezinambuzane ezinobuthi ngempazamo, okanye ungaziboni iinyoka, awuboni umngxuma ophambi kwakho, kwaye ungxamile ungene esitratweni umzuzwana, njalo njalo. .Ezinye iimpawu, ezifana ne-Knight Cole, mhlawumbi zithathela ingqalelo oku, ngoko zibonelela ngokhetho lwenguqulo ye-CRI kunye nonikezelo oluphezulu lombala kwimigca emininzi yemveliso.
Malunga nobushushu bombala
Umgaqo we-LED emhlophe kukuba i-electron ikhupha ukukhanya okuluhlaza okwesibhakabhaka nge-chip, kwaye ivuselela i-phosphor ukuba ikhuphe ukukhanya okuphuzi, okuxutywe kukukhanya okumhlophe.Ukunikezelwa kombala wokukhanya okutyheli okuchulumancisayo yiphosphor kuphezulu kakhulu, ngelixa ukukhanya okuluhlaza kukukhanya kwe-monochromatic.Ngoko ke, ukuphucula unikezelo lombala, kufuneka sandise umlinganiselo wokukhanya okutyheli.
Ukusuka kulo mbono, ukufudumala kombala okhanyayo, bhetele ukunikezelwa kombala, kwaye kufanelekile kwimidlalo yangaphandle.Ukongeza, ukushisa kombala wokukhanya kombala ofudumeleyo kuphantsi, ubude be-waveleng bude, ukungena kunamandla kwimozulu yemvula kunye nenkungu, kwaye i-irradiation ide.Ezi mpawu ngokudibeneyo zimisela imfuno yokukhanya kombala ofudumeleyo we-LED kwimidlalo yangaphandle.
Nangona kunjalo, kwelinye icala, ukusebenza kakuhle kwe-fluorescence enomdla kuphantsi.Ukukhanya okupheleleyo kwe-LED emhlophe efudumeleyo kuya kuba ngaphantsi, kwaye umbala okhanyayo uya kubonakala umnyama kwaye utyheli, oya kudayya into ene-radiated njengesibane esine-incandescent esinamandla aphantsi.Ke ngoko, xa lilonke, kufanelekile ukukhetha iimveliso ze-LED ezimhlophe eziphakathi kwimidlalo yangaphandle, engenambala nje wonikezelo olufanelekileyo kunye nokungena, kodwa ikwanqanda ukuncitshiswa kokuqaqamba kunye nokudaya.
