Kuyini ukukhanya kwe-LED strip?
Izibani ze-LED strip ziyizindlela ezintsha neziguquguqukayo zokukhanya. Kunokuhlukahluka okuningi nokungafani, kepha ingxenye enkulu, banezici ezilandelayo:
● Kuhlanganisa ama-enditter amaningi e-LED afakwe ebhodini elincane, eliguquguqukayo
● Sebenzisa amandla we-DC aphansi aphansi
● Atholakala ngombala ohlukahlukene we-Fixed and Okuguquguqukayo nokukhanya
● Thumela ku-reel ende (ngokujwayelekile amamitha ayi-16 / amamitha ayi-5), ungasikwa ubude, futhi kufaka phakathi ukunamathela kwezinhlangothi ezimbili
I-anatomy ye-LED strip
Ukukhanya kwe-LED strip kuvamisile i-inch (10-12 mm) ububanzi, kuze kufike kumamitha ayi-16) noma ngaphezulu ngobude. Bangasikwa ngobude obuthile besebenzisa isikere nje esikhaleni, etholakala njalo ngamasentimitha ayi-1-2.
Ama-LED ngazinye abekwe eceleni kwe-strip, imvamisa emihlanganweni engama-18- 36 e-LED ngonyawo (60-120 imitha ngayinye). Umbala okhanyayo nekhwalithi ye-LED yomuntu ngamunye kunquma umbala olula okhanyayo nekhwalithi ye-LED strip.
I-backside ye-LED strip ifaka ukunamathela okukhulu okusetshenzisiwe okufakiwe. Mane nje uphume ku-liner, bese ubeka umucu we-LED cishe kunoma iyiphi indawo. Ngoba i-Circuitboard yakhelwe ukuba iguquguqukayo, imichilo eholwayo ingafakwa endaweni egobile futhi engalingani.
Ukunquma ukugqama kwe-LED strip
Ukukhanya kwemichilo ye-LED kunqunywa kusetshenziswa i-metricamalensi. Ngokungafani nama-Incandescent Bulbs, imichilo ehlukile ye-LED ingaba namazinga ahlukene okusebenza kahle, ngakho-ke isilinganiso sokukhula asihlali sinenjongo ekunqumeni ukuphuma kwangempela kokukhanya.
Ukukhanya kwe-LED strip kuvame ukuchazwa kuma-lumens ngonyawo (noma imitha). Umucu oholwa yikhwalithi enhle kufanele ahlinzeke okungenani ama-450 ama-lumens ngonyawo ngakunye (ama-lumens ayi-1500 ngemitha ngayinye), enikeza cishe inani elifanayo lokukhipha okukhanyayo ngonyawo njenge-T8 Fluorescent Lamp. (Isib. 4-ft t8 fluorescent = 4-ft of LED strip = 1800 lumens).
Ukukhanya kwe-LED strip kunqunywa ngokuyinhloko yizici ezintathu:
● Ukukhishwa okukhanyayo kanye nokusebenza kahle kwe-Emitter ye-LED
● Inani lama-LED ngonyawo ngalunye
● Ukudonswa kwamandla kwe-LED strip ngonyawo ngonyawo
Ukukhanya kwe-LED strip ngaphandle kokucaciswa kokukhanya ku-lumens ifulegi elibomvu. Futhi uzofuna ukuqaphela ukuthola izindleko eziphansi ze-LED imichilo ebiza ukukhanya okuphezulu, ngoba ingakhipha ukwehla ukuze ukhiphe ama-LED aze ahluleke ngaphambi kwesikhathi.
Density ye-LED nokudweba kwamandla
Ungahle uwele kuwo amagama ahlukahlukene we-Emitter enjenge-2835, 3528, 5050 noma 5730. Ungakhathazeki kakhulu ngalokhu, njengoba okubaluleke kakhulu ku-LED stred unyawo ngonyawo ngalunye, kanye nokudweba kwamandla ngonyawo ngalunye.
Ubuningi be-LED bubalulekile ekunqumeni ibanga phakathi kwama-LED (pitch) nokuthi kuzoba nezindawo ezibonakalayo noma cha ezibonakalayo noma amabala amnyama phakathi kwama-LED Emitters. Ubuningi obuphezulu bama-36 ama-LED ngonyawo ngakunye (ama-LEDs angama-120 ngemitha ngayinye) ngokujwayelekile kuzohlinzeka ngomphumela wokukhanyisa omuhle kakhulu, osatshalaliswa kakhulu. I-LED Enditters iyingxenye ebiza kakhulu ye-LED strip ekhiqizayo, ngakho-ke qiniseka ukuthi ulandisa ngomehluko wobunzima be-LED lapho uqhathanisa amanani entengo e-LED.
Okulandelayo, cabanga ngamandla okukhanya okukhanya kwe-LED strip ngonyawo ngonyawo. Umdwebo wamandla usitshela inani lamandla uhlelo oluzodla, ngakho-ke lokhu kubalulekile ukuthola izindleko zakho zikagesi nezidingo zokunikezwa kwamandla (bheka ngezansi). Umucu oholwa yikhwalithi enhle kufanele ube namandla okuhlinzeka ama-watts ama-4 ngonyawo noma ngaphezulu (15 w / met).
Ekugcineni, yenza isheke elisheshayo lokuthola ukuthi ngabe ama-LED ngamunye ahoxiswa ukwehlukanisa i-wattage ngonyawo ngonyawo lwe-LED ngonyawo nge-LED ngonyawo nge-LED ngonyawo nge-LED ngonyawo ngonyawo. Ngomkhiqizo we-LED strip, kuvame ukuba yisibonakaliso esihle uma ama-LED akhishwe ngaphezulu kwama-watts angu-0,2 yileso.
Izinketho zombala we-LED strip: mhlophe
Izibani ze-LED strip zitholakala ngemithunzi ehlukahlukene yabelungu noma imibala. Ngokuvamile, ukukhanya okumhlophe kuyindlela ewusizo kakhulu futhi ethandwa kakhulu yezinhlelo zokusebenza zokukhanyisa ngaphakathi.
Ngokuchaza izithunzi ezihlukile nezimfanelo zokushisa okumhlophe, okushisa kombala (i-CCT) kanye ne-Colour Rendering Index (CRI) ngamamethrikhi amabili abalulekile ukukhumbula.
Ukushisa kombala kuyisilinganiso sendlela "efudumele" noma "epholile" umbala okhanyayo. Ukukhanya okuthambile kwesibalo sendabuko sendabuko kunamazinga okushisa anemibala ephansi (2700k), ngenkathi i-crisp, emhlophe emhlophe yemvelo yemvelo inamazinga okushisa aphezulu (6500k).
Ukuhumusha kombala kuyisilinganiso sendlela imibala eqondile evela ngaphansi komthombo wokukhanya. Ngaphansi komlomo ophansi we-CRI LED, imibala ingahle ibonakale ihlanekezelwe, igezwe, noma ihlupheke. Imikhiqizo ephezulu ye-CRI LED inikela ngokukhanya okuvumela ukuthi izinto zibonakale ngendlela ezokwazi ngaphansi komthombo wokukhanya omuhle njenge-halogen lamp, noma ukukhanya kwemini yemvelo. Futhi funa inani le-R9 elikhanyayo, elinikeza eminye imininingwane mayelana nokuthi imibala ebomvu ihunyushwa kanjani.
Izinketho zombala we-LED strip: umbala oguquliwe noguquguqukayo
Kwesinye isikhathi, ungahle udinge umphumela we-punchy, ogcwele umbala. Kulezi zimo, imichilo ye-LED enemibala inganikeza imiphumela emihle yokukhanyisa nemidlalo yesethi. Imibala kuyo yonke indawo ebonakalayo ebonakalayo iyatholakala - i-violet, eluhlaza okwesibhakabhaka, eluhlaza okotshani, i-amber, ebomvu - ngisho ne-ultraviolet noma infrariolet noma infragilet.
Kunezinhlobo ezimbili eziyinhloko zomucu we-LED onemibala: umbala owodwa olungiselelwe, kanye nokushintsha kombala. Umugqa we-LED COLOCED olungiselelwe ukhipha umbala owodwa nje, futhi inqubo yokusebenza ifana nemichilo eholwa elimhlophe esixoxe ngenhla. Umucu we-LED oguqula umbala uqukethe iziteshi zombala eziningi emgqeni owodwa we-LED. Uhlobo oluyisisekelo oluyisisekelo luzofaka iziteshi ezibomvu, eziluhlaza futhi eziluhlaza okwesibhakabhaka (RGB), okukuvumela ukuba uhlanganise ama-Colour Colon ahlukahlukene ku-Fly.
Ezinye zizovumela ukulawulwa okunamandla kwe-White Colour Temperative Tuning noma ngisho nokushisa kombala kanye nama-RGB aues.
Vertage Off Voltage & Amandla
Imichilo eminingi ye-LED ilungiselelwe ukusebenza ku-12V noma i-24V DC. Lapho usuka kuma-mains ezijwayelekile ahlinzekela amandla omthombo wamandla (isib Lokhu kuvame kakhulu futhi kumane kufezeke kusetshenziswa amandla kagesi we-DC.
Qiniseka ukuthi ukunikezwa kwamandla kwakho kwaneleAmandla Amandlaukunika amandla imichilo ye-LED. Wonke ama-DC Power Supply azofaka ohlwini lwamanje alinganiselwe alinganiselwe (kuma-amps) noma amandla (kuma-watts). Nquma ukudonswa kwamandla okuphelele komucu we-LED usebenzisa ifomula elandelayo:
● Amandla = Amandla we-LED (nge-PER FT) X LED strip ubude (ku-ft)
Isibonelo Isimo Ukuxhuma 5 ft of LED strip lapho ukusetshenziswa kwamandla oku-LED strip kungu-4 watts ngonyawo ngonyawo olungu-4:
● Amandla = 4 Watts per ft ft x 5 ft = =Ama-Watts angama-20
Ukudweba kwamandla ngonyawo (noma imitha) cishe kuhlale kubhalwe ku-datasheet ye-LED strip.
Awunasiqiniseko uma kufanele ukhethe phakathi kwe-12V ne-24V? Konke okunye okulinganayo, i-24v ngokuvamile ukubheja kwakho okuhle kakhulu.
