Kuyini ukukhanya kwe-LED Strip?
Izibani ze-strip ze-LED ziyizinhlobo ezintsha nezishintshashintshayo zokukhanyisa. Kunokuhlukahluka okuningi nokuhlukile, kodwa ingxenye enkulu, banezici ezilandelayo:
● Iqukethe ama-emitter amaningi e-LED afakwe ebhodini lesifunda elincane, eliguquguqukayo
● Sebenzisa amandla e-DC ane-voltage ephansi
● Atholakala ngemibala ehlukahlukene engaguquki futhi eguquguqukayo kanye nokukhanya
● Umkhumbi ngosondweni olude (imvamisa engamafidi angu-16 / 5 wamamitha), ungasikwa ube ubude, futhi uhlanganise nokunamathelayo okunezinhlangothi ezimbili ukuze kufakwe
I-Anatomy yomugqa we-LED
Isibani somugqa we-LED ngokuvamile siwuhhafu weyintshi (10-12 mm) ububanzi, futhi kufika ku-16 amafidi (5 amamitha) noma ngaphezulu ubude. Zingasikwa zibe ubude obuthile zisebenzisa isikere nje eduze kwemigqa yokusika, etholakala njalo ngamasentimitha angu-1-2.
Ama-LED angawodwana agxunyekwe emgqeni, ngokuvamile ekuminyanisweni kwama-LED angu-18-36 ngonyawo (60-120 imitha). Umbala okhanyayo nekhwalithi yama-LED angawodwana kunquma umbala okhanyayo uwonke kanye nekhwalithi yomugqa we-LED.
Ingemuva le-strip ye-LED ifaka i-adhesive efakwe ngaphambili ezinhlangothini ezimbili. Vele ukhumule i-liner, bese ukhweza umucu we-LED cishe kunoma iyiphi indawo. Ngenxa yokuthi i-circuitboard yakhelwe ukuthi ikwazi ukuguquguquka, imichilo ye-LED ingafakwa ezindaweni ezigobile nezingalingani.
Ukunquma Ukugqama Komugqa We-LED
Ukukhanya kwemichilo ye-LED kunqunywa kusetshenziswa imethrikhilumens. Ngokungafani nama-incandescent bulb, imichilo ye-LED ehlukene ingaba namazinga ahlukene okusebenza kahle, ngakho-ke isilinganiso samanzi asihlali sisho okuthile ekunqumeni ukuphuma kokukhanya kwangempela.
Ukukhanya kwemichilo ye-LED ngokuvamile kuchazwa ngamalumen ngonyawo (noma imitha). Umugqa we-LED wekhwalithi enhle kufanele unikeze okungenani ama-lumens angu-450 ngonyawo (1500 lumens per imitha), ohlinzeka cishe inani elifanayo lokukhanya okukhiphayo ngonyawo njengesibani esivamile se-T8 fluorescent. (Isibonelo, i-4-ft T8 fluorescent = 4-ft ye-LED strip = 1800 lumens).
Ukukhanya kwemichilo ye-LED kunqunywa ngokuyinhloko izici ezintathu:
● Okukhipha ukukhanya nokusebenza kahle nge-emitter ngayinye ye-LED
● Inani lama-LED ngonyawo ngalunye
● Ukudonswa kwamandla komugqa we-LED ngonyawo ngalunye
Ukukhanya komugqa we-LED ngaphandle kokucaciswa kokukhanya kuma-lumens kuyifulegi elibomvu. Uzophinde ufune ukuqaphela imichilo ye-LED ebiza kancane ethi ifuna ukukhanya okuphezulu, njengoba ingase ishayele ngokweqile ama-LED aze ahluleke ngaphambi kwesikhathi.
I-LED Density & Power Draw
Ungase uhlangane namagama ahlukahlukene we-LED emitter afana no-2835, 3528, 5050 noma 5730. Ungakhathazeki kakhulu ngalokhu, njengoba okubaluleke kakhulu emgqeni we-LED inombolo yama-LED ngonyawo, kanye nokudonsa amandla ngonyawo ngalunye.
Ukuminyana kwe-LED kubalulekile ekunqumeni ibanga eliphakathi kwama-LED (iphimbo) kanye nokuthi kuzoba khona yini izindawo ezishisayo ezibonakalayo namachashaza amnyama phakathi kwama-LED emitters. Ukuminyana okuphezulu kwama-LED angu-36 ngonyawo (ama-LED angu-120 imitha) ngokuvamile azohlinzeka ngomphumela wokukhanya ongcono kakhulu, osabalaliswe ngokulinganayo. Ama-LED emitter ayingxenye ebiza kakhulu yokukhiqizwa kwe-LED strip, ngakho-ke qiniseka ukuthi ulandisa ngomehluko wokuminyana kwe-LED uma uqhathanisa amanani e-strip ye-LED.
Okulandelayo, cabanga ngomdwebo wamandla wesibani se-LED ngonyawo ngalunye. Ukudonswa kwamandla kusitshela inani lamandla azosetshenziswa isistimu, ngakho-ke lokhu kubalulekile ukuze unqume izindleko zakho zikagesi kanye nezidingo zokuphakelwa kwamandla (bona ngezansi). Umugqa we-LED wekhwalithi enhle kufanele ukwazi ukunikeza ama-watts angu-4 ngonyawo noma ngaphezulu (15 W/imitha).
Okokugcina, yenza ukuhlola okusheshayo ukuze uthole ukuthi ingabe ama-LED angawodwana ashayelwa ngokweqile yini ngokuhlukanisa amanzi ngonyawo ngalunye ngobuningi be-LED ngonyawo ngalunye. Ngomkhiqizo we-strip ye-LED, ngokuvamile kuwuphawu oluhle uma ama-LED engashayelwa ngaphezu kwama-watts angu-0.2 lilinye.
Izinketho Zombala We-strip ye-LED: Emhlophe
Izibani ze-strip ze-LED zitholakala ngemibala ehlukahlukene emhlophe noma enemibala. Ngokuvamile, ukukhanya okumhlophe kuyindlela ewusizo kakhulu futhi ethandwayo yezinhlelo zokusebenza zokukhanyisa endlini.
Ekuchazeni amathunzi ahlukene kanye nezimfanelo zomhlophe, izinga lokushisa lombala (CCT) kanye nenkomba yokunikeza umbala (CRI) amamethrikhi amabili okubalulekile ukukhumbula.
Izinga lokushisa lombala isilinganiso sokuthi umbala wokukhanya "ufudumele" noma "upholile" uvela kanjani. Ukukhanya okuthambile kwesibani sosiko se-incandescent kunokushisa kombala ophansi (2700K), kuyilapho okucwebile, okumhlophe okukhanyayo kokukhanya kwasemini kwemvelo kunokushisa kombala okuphezulu (6500K).
Ukunikezwa kombala isilinganiso sokuthi imibala enembe ivela kanjani ngaphansi komthombo wokukhanya. Ngaphansi komugqa we-LED we-CRI ophansi, imibala ingase ibonakale ihlanekezelwe, igezekile, noma ingabonakali. Imikhiqizo ye-High CRI LED inikeza ukukhanya okuvumela izinto ukuthi zibonakale ngendlela ebezingabonakala ngayo ngaphansi komthombo wokukhanya okahle njengesibani se-halogen, noma ukukhanya kwemini kwemvelo. Futhi bheka inani elingu-R9 lomthombo wokukhanya, elihlinzeka ngolwazi olwengeziwe mayelana nendlela imibala ebomvu enikezwa ngayo.
Izinketho Zombala We-strip ye-LED: Umbala Olungisiwe Noguquguqukayo
Ngezinye izikhathi, ungase udinge umphumela wombala ogqamile, ogcwele. Kulezi zimo, imichilo ye-LED enombala inganikeza ukugcizelela okuhle kanye nemiphumela yokukhanyisa yaseshashalazini. Imibala kuyo yonke i-spectrum ebonakalayo iyatholakala - violet, blue, green, amber, red - ngisho ne-ultraviolet noma infrared.
Kunezinhlobo ezimbili eziyinhloko zomugqa we-LED onemibala: umbala owodwa ongashintshi, nokushintsha kombala. Umugqa we-LED wombala ongashintshi ukhipha umbala owodwa nje, futhi umgomo wokusebenza ufana nje nemicu ye-LED emhlophe esixoxe ngayo ngenhla. Umugqa we-LED oshintsha umbala uqukethe amashaneli anemibala emugqeni owodwa we-LED. Uhlobo oluyisisekelo kakhulu luzobandakanya amashaneli abomvu, aluhlaza okwesibhakabhaka (i-RGB), okukuvumela ukuthi uhlanganise ngamandla izingxenye zemibala ehlukahlukene empukaneni ukuze uzuze cishe noma yimuphi umbala.
Abanye bazovumela ukulawula okuguquguqukayo kokushintsha kwezinga lokushisa lombala omhlophe noma kokubili izinga lokushisa lombala nemibala ye-RGB.
Okokufaka I-Voltage & Power Supply
Imichilo eminingi ye-LED ilungiselelwe ukuthi isebenze ku-12V noma ku-24V DC. Lapho uphela umthombo wamandla kagesi oyinhloko ojwayelekile (isb. indawo yokukhipha udonga lwasendlini) ku-120/240V AC, amandla kumele aguqulelwe kusignali ye-DC efanelekile ye-voltage ephansi. Lokhu kuvame kakhulu futhi kufezwa kalula kusetshenziswa ugesi we-DC.
Qiniseka ukuthi ugesi wakho waneleumthamo wamandlaukunika amandla imichilo ye-LED. Yonke indawo kagesi ye-DC izofaka ohlwini lwamanje olulinganiselwe lwamanje (kuma-Amps) noma amandla (ngama-Watts). Nquma umthamo wamandla ophelele womugqa we-LED usebenzisa ifomula elandelayo:
● Amandla = Amandla e-LED (ngeft) x ubude bomugqa we-LED (ku-ft)
Isibonelo sesimo sokuxhuma i-5 ft yomugqa we-LED lapho ukusetshenziswa kwamandla komugqa we-LED kungu-4 Watts ngonyawo ngalunye:
● Amandla = 4 Watts ngeft x 5 ft =20 Watts
Ukudonsa amandla ngonyawo ngalunye (noma imitha) cishe njalo kufakwe ohlwini lwemininingwane yomugqa we-LED.
Awuqinisekile ukuthi kufanele ukhethe phakathi kwe-12V ne-24V? Konke okunye kuyalingana, i-24V ngokujwayelekile ingukubheja kwakho okuhle kakhulu.
