Izixhobo kunye nezinto ezichaza ukusebenza kwe-LED Strip

Ukukhetha izixhobo ezifanelekileyo sisiseko somgangatho we-LED strip kunye nokusebenza kwexesha elide. Umbindi we-LED strip uquka ii-LED, ibhodi yesekethe eprintiweyo (i-PCB), ii-resistor okanye ii-constant-current drivers, ii-solder joints, kunye ne-protective encapsulation. Zonke ezi zinto ziza ngeendlela ezahlukeneyo, kwaye izigqibo ezenziwa kweli nqanaba ziqhuba ukukhanya, umgangatho wombala, ukusebenza kakuhle, ukuguquguquka, kunye nobomi bomsebenzi.

Iitships ze-LED ngokwazo ziyafumaneka njengeepakeji ezizimeleyo ezifana ne-SMD 3528, 5050, 2835, kunye neefomathi ezintsha ezisebenzayo. Uyilo lwetships luchaphazela ukuba zingaphi ii-emitters kwi-diode nganye, indlela ubushushu obulawulwa ngayo ngaphakathi, kunye nemveliso ye-lumen enokufezekiswa nge-watt nganye. Umzekelo, ezinye iipakeji ze-SMD zenzelwe ukuxhasa umbane ophezulu kunye nokuhanjiswa kobushushu okungcono, okuvumela ukukhanya okuphezulu ngaphandle kokuncipha kwe-lumen ngaphambi kwexesha. Ukongeza kwii-LED eziqhelekileyo, abavelisi banokusebenzisa itekhnoloji ye-COB (chip-on-board) ukubonakala kokukhanya okufanayo kunye nokunxibelelana kobushushu okuphuculweyo, okubonelela ngebha yokukhanya ethambileyo kodwa idla ngokufuna uyilo olwahlukileyo lwe-PCB kunye nolawulo lobushushu.

Ii-PCB ziyahluka ukusuka kwi-single-layer flexible substrates ukuya kwi-multilayer rigid-flex designs ezinobukhulu obahlukeneyo be-copper. Ubukhulu be-copper kunye nobubanzi be-trace bubalulekile kuba zichaphazela amandla okuthwala umbane kunye nokusasazeka kobushushu. Ubhedu olutyebileyo kunye ne-trace traces ezibanzi zinciphisa ilahleko zokumelana kunye nokufudumeza, okuvumela ukuba kusebenze ixesha elide ngaphandle kokwehla kwe-voltage kwaye kuxhase uxinano oluphezulu lwe-lumen. Ii-Flex PCB ziza kwi-polyimide okanye kwi-polyester bases; i-polyimide ayitshisi kakhulu kwaye ingcono kwiinkqubo zobushushu obuphezulu, ngelixa i-polyester ingabizi kakhulu kodwa ayinamandla xa ibonakaliswa ixesha elide. Uyilo lwee-pad kunye nokukwazi ukunyibilikisa kubalulekile ekuhlanganiseni okuthembekileyo; ii-pad eziyilwe kakuhle zinceda ukunciphisa uxinzelelo loomatshini kwi-solder joints ngexesha lokugoba.

Iiresistor kunye nabaqhubi zilawula umbane. Iiresistor zemveli zilula kwaye zingabizi kakhulu kwiistrips ezingabizi kakhulu, kodwa ii-constant-current drivers okanye ii-IC ezidibeneyo zibonelela ngemveliso ezinzileyo ngakumbi kubushushu kunye notshintsho lonikezelo—zibalulekile kwiistrips apho ukuhambelana kombala kunye nobomi obude kubalulekile. Kwiistrips ezinokulungiselelwa, iitships zomqhubi ezidibeneyo kwistrip (umz., abalawuli bohlobo lwe-WS281x) zilawula ii-LEDs nganye kodwa zifuna uyilo olucokisekileyo ukuze kuthintelwe imiba yokuthembeka kwesignali kumgama omde.

Iindlela zokufaka ii-capsulation—akukho, i-silicone coating, okanye i-full potting—zichaphazela ukuqina kunye nenkangeleko. Ii-strips ezingafakwanga ii-capsulated zibiza kancinci kwaye zifanelekile ukusetyenziswa ngaphakathi. Ii-silicone okanye ii-epoxy coating zongeza ukufuma kunye nokumelana nokurhawuzelelwa kwaye zinokucaca ekukhanyeni okuphezulu okanye zisasazeke ukuze zibukeke zithambile. I-silicone inika ukuqina okungcono kwe-UV kunye nobushushu kunee-epoxies ezininzi. Kwizicelo zangaphandle okanye ezingaphantsi kwamanzi, ii-potting compounds kunye nee-resin ezenziwe ngokukodwa zibonelela ngokhuseleko oluphezulu kodwa zonyusa ukumelana nobushushu kwaye zinokunciphisa ukukhutshwa kokukhanya kancinci.

Izihlanganisi, izincamathelisi, kunye nezixhobo zokufakela zigqibezela umfanekiso wezinto ezibonakalayo. Umgangatho we-adhesive backing backup uchaphazela ukhuseleko lokufakelela ixesha elide, ngakumbi kwiindawo ezinobushushu obujikelezayo. Izihlanganisi kufuneka zilinganiswe ngokombane olindelekileyo kwaye kufuneka zihambelane neemfuno zoomatshini kunye nokusingqongileyo ze-strip. Xa ucacisa izixhobo, cinga ngokusebenzisana—umzekelo, i-strip enamandla aphezulu ene-PCB copper enganeleyo kunye ne-adhesive encinci iya kutshisa kakhulu kwaye ihlukane ngaphambi kwexesha. Ukucinga kwenkqubo ukusuka ekupheleni ukuya ekupheleni kubalulekile: yonke into inegalelo kwindlela esebenza ngayo umbane, i-optical, kunye ne-mechanical ye-strip.

Ukukhanya okuphumayo, Umgangatho woMbala, kunye neeMetriki zoBukhazikhazi

Ukuqonda indlela abavelisi abalinganisa ngayo baze babonise ngayo ukusebenza kokukhanya kubalulekile ekukhetheni umcu ochanekileyo we-LED. Ukukhanya akulona inani elinye; kuchazwa ziimetrikhi ezininzi ezichaza indlela umcu oza kusebenza ngayo ngokubonakalayo nangokusebenzayo. Iimetrikhi eziphambili ziquka ii-lumens, ukusebenza kakuhle kokukhanya (i-lumens nge-watt nganye), ubushushu bombala obuhambelanayo (i-CCT), isalathisi sokuboniswa kombala (i-CRI), ii-chromaticity coordinates, kunye nokusasazwa kwemitha.

Ii-lumens zibonelela ngomlinganiselo opheleleyo wokukhanya, kodwa ii-strips ezimbini ezine-lumen rating efanayo zinokubonakala zahlukile ngokuxhomekeke ekusasazekeni kwe-beam kunye nokufakelwa komphezulu. Ukusebenza kakuhle okukhanyayo kudibanisa ukukhanya nokusetyenziswa kwamandla. Ii-strips ezisebenzayo ngakumbi zibonelela ngee-lumens eziphezulu xa kusetyenziswa amandla aphantsi, kubalulekile kulawulo lobushushu kunye neendleko zokusebenza. Abavelisi badla ngokucaphula ii-lumens ngemitha nganye kwiimveliso ze-strip ukunika abayili inani elisebenzayo lokucacisa ukusebenza; nangona kunjalo, eli xabiso lixhomekeke kumbane we-drive, uyilo lwe-PCB, kunye nokukhetha i-encapsulation.

I-CCT ichaza umbala obonakalayo wokukhanya okumhlophe, ochazwa kwiiKelvins. Iinketho eziqhelekileyo ziquka umhlophe ofudumeleyo (2700–3000K), umhlophe ongathathi cala (3500–4000K), umhlophe opholileyo (5000–6500K), kunye nomhlophe oguqulwayo onokuguqulwa ngokwezifiso ovumela ukulungiswa okuguqukayo. Ukukhethwa kwe-CCT kuchaphazela imeko-bume kunye nokufaneleka kwemisebenzi; imibala efudumeleyo ikhethwa kwiindawo zokuhlala zokwamkela iindwendwe, ngelixa imibala epholileyo ingasetyenziselwa ukukhanyisa imisebenzi okanye indawo yokubonisa. Abavelisi kufuneka banike ukunyamezelana okuqinileyo kwe-CCT kunye nolwazi lokufaka izinto ezigciniweyo ukuqinisekisa ukuhambelana kuzo zonke iibhetshi zemveliso.

Ukuboniswa kombala kulinganisa indlela imibala ebonakala ngayo ngokwemvelo phantsi komthombo wokukhanya. I-CRI yindlela eqhelekileyo yokulinganisa, kodwa inemida, ingakumbi xa kuthelekiswa imibala egcweleyo okanye ecacileyo; ukuboniswa okude okufana ne-TM-30 kunika ulwazi oluthe kratya. Kwizicelo apho ukuboniswa kombala ngokuchanekileyo kubaluleke kakhulu—ukuthengisa, iigalari, okanye useto lwezonyango—chaza amaxabiso aphezulu e-CRI (angaphezu kwama-90 akhethwayo). Ukukhanya okulula kwe-accent, i-CRI 80 okanye i-85 inokwanela.

Kwimigca ye-RGB okanye ye-RGBW, i-color gamut kunye nesisombululo solawulo zibalulekile. Imicu ekwaziyo ukulungiselelwa ivumela iipateni zemibala eziguqukayo kunye nee-animations kodwa ifuna abalawuli kunye nokusasazwa kwamandla okugcina ukuthembeka kombala okufanayo kulo lonke umgca. Ukuxuba umhlophe nezinto ze-RGB (RGBW, RGBWW) kunika umbala omhlophe otyebileyo kunye neethoni ze-pastel, kodwa umgangatho wokudibanisa—indlela ii-LED ezibekwa ngayo kwaye zisasazwa ngayo—uchaphazela ukudibana kombala.

Uvavanyo lwe-photometric lubalulekile. Khangela iifayile ze-photometric ezibonelelwe ngumvelisi (i-IES okanye i-LDT) ukuze ufumane ukuhlanganiswa okuchanekileyo koyilo kunye nokukhanya kunye nokufana kwemodeli. Ukongeza kwimilinganiselo yesimo esizinzileyo, cinga ngendlela ukukhanya okuncipha ngayo ngokuhamba kwexesha; iingxelo ze-LM-80 kunye neeprojektha ze-TM-21 zibonelela ngokugcinwa kwe-lumen elinganisiweyo yee-LED kunye noqikelelo lobomi obuvela kwi-extrapolated. Ekugqibeleni, ukukhanya kunye nomgangatho wombala kuvela kudibaniso lokukhethwa kwe-chip, iimeko zokuqhuba, ulawulo lobushushu, uyilo lwe-optical, kunye nolawulo oluchanekileyo lokuvelisa.

Ukuqina, Uvavanyo Lwendalo, kunye Nokuthembeka Kwexesha Elide

Ukuqina kwemicu ye-LED kudlula ubulukhuni obulula; kubandakanya ukumelana nokufuma, ukuzinza kwe-UV, ukumelana nokukrweleka, ukuqina kokujikeleza kobushushu, kunye nokuqina koomatshini. Ukulinganiswa kwendalo okufana ne-IP (ingress protection) kunye ne-IK (impact protection) kubonelela ngeendlela ezisemgangathweni zokunxibelelana ngendlela imveliso eya kumelana ngayo neengozi ezithile. Ukulinganiswa kwe-IP okufana ne-IP20, IP65, IP67, kunye ne-IP68 kubonisa amanqanaba okhuseleko akhulayo eluthulini nasemanzini, apho i-IP68 idla ngokubonisa ukufaneleka kokuntywiliselwa rhoqo kubunzulu obuchaziweyo xa ivalwe ngokufanelekileyo.

Izixhobo kunye nokuhlanganiswa kwazo zimisela ukuba umcu uhlangabezana njani nezi zilinganiso. Iintlobo ze-encapsulation—i-silicone ecacileyo, i-silicone esasazekileyo, okanye ii-resin ezizinzileyo ze-UV—zikhusela ekufuma kunye nokungena kwamasuntswana kodwa zahlukile ngokuguquguquka kunye nokuzinza kwexesha elide. Ii-encapsulants ze-silicone zikhethwa ukusetyenziswa ngaphandle kuba ziyamelana nokutyheli kunye nokuqhekeka phantsi kokuvezwa yi-UV kwaye zigcina ukuthamba kuzo zonke iinguqu zobushushu. Nangona kunjalo, i-silicone inokubiza kakhulu kwaye ifuna ulawulo oluthile lokukhupha kunye nokulungisa ngexesha lokwenziwa.

Ukusasazwa kwamandla kunye nokuhla kwe-voltage kuba yinto ebalulekileyo kwiindlela ezinde. Abayili kufuneka bacebe iindawo zokuphakela ezifanelekileyo okanye basebenzise i-daisy-chaining ene-conductors zamandla amakhulu. Kwiifekthi zamandla aphezulu, ii-DC power injection points rhoqo emva kwemitha ezimbalwa okanye ukusebenzisa ii-high-voltage strips (24V okanye 48V) kunciphisa ukuhla kwe-voltage kwaye kunceda ukugcina ukukhanya okufanayo kubude. Ii-addressable strips zinemida ethile yokuthembeka kwesignali yedatha; ii-termination resistor, ii-twisted pairs zemigca yesignali, kunye nobude obucetywayo be-segment obuphezulu bunceda ukugcina ukusebenza okuthembekileyo.

Ukulula kokugcinwa kuchaphazela ulwaneliseko lwexesha elide. Izihlanganisi zeModular, iindawo ezinokutshintshwa, kunye neendlela zokufakelwa ezifikelelekayo zenza kube lula ukulungiswa kunye nokulungiswa kwakhona. Kwiindawo ezisetyenziswa kakhulu okanye zorhwebo, cinga ngeemicu ezifakwe kwiiprofayili ezine-snap-in diffusers ezinokutshintshwa ngaphandle kwe-strip ngokwayo.

Ukhuseleko lomsebenzisi kunye nokuthobela ikhowudi nako kubalulekile. Qinisekisa ukuba imicu ichazwe ngezigqubuthelo ezifanelekileyo zokukhusela okanye iitshaneli kwiimeko apho zinokudibana nabantu okanye izinto ezitshayo. Qinisekisa ukuba ufakelo luhlangabezana neekhowudi zombane zasekuhlaleni kwaye naziphi na izixhobo zamandla zangaphandle zinemvume yokhuseleko efunekayo kunye nokhuseleko olugqithisileyo.

Okokugqibela, cinga ngezinto ezichaphazela abantu: ukuhambelana kokukhanya, ukusebenza kokukhanya, kunye nokuzinza kombala phantsi kweendlela ezahlukeneyo zokukhanya. Ii-triac dimmers, ii-PWM dimmers, kunye nabaqhubi be-constant-current basebenzisane ngokwahlukileyo ne-LED electronics. Ukukhetha iinxalenye kunye nabalawuli abenzelwe ukusebenza kunye kuthintela ukukhanya, ukutshintsha kombala, kunye nokunciphisa ixesha lokuphila. Ukubonelela ngezikhokelo zokufakela ezicacileyo, izixhobo ezicetyiswayo, kunye neendlela zokulungisa ezicetywayo kunciphisa iingxaki zasentsimini kwaye kuphucula amava omsebenzisi wokugqibela.

Ngamafutshane, ukukhetha okanye ukuvelisa izibane ze-LED ezithembekileyo nezintle kufuna ingqalelo kwizinto ezisetyenziswayo, ukusebenza kwe-optical, ukuqina, iindlela zokuvelisa, kunye noyilo lokufakela. Isigqibo ngasinye—ukusuka kubukhulu be-PCB yobhedu ukuya kwi-encapsulation chemistry, icebo le-LED binning ukuya kukhetho lwe-connector—sithwala urhwebo phakathi kweendleko, ukusebenza kakuhle, kunye nobude bexesha. Ngokuqonda indlela ezi zinto ezisebenzisana ngayo, ungacacisa ii-strips ezihlangabezana neenjongo ezibonakalayo kunye neemfuno zokusebenza.

Ukuze siphinde siqwalasele izinto ezibalulekileyo ekufuneka zenziwe: beka phambili ulawulo lobushushu kunye nomgangatho wezinto ukuqinisekisa ukuba zihlala ixesha elide, gxininisa kwidatha eneenkcukacha ze-photometric kunye nokuthembeka ukuqinisekisa ukusebenza, kwaye ucwangcise amaqhinga okufakela anciphisa ukuhla kwe-voltage, uxinzelelo loomatshini, kunye nokuvezwa kokusingqongileyo. Ukukhetha umenzi oneenkqubo zokuvavanya ezicacileyo kunye neendlela zokwenza ngokwezifiso eziguquguqukayo kuya konga ixesha kunye nemali kuyo nayiphi na iprojekthi yokukhanyisa.
