Ezi micu zihlala zikhethwa kwiindawo ezivezwe kufutshane nemigca yokubona apho ukubonakala okungaphazanyiswanga kunceda ekubukekeni okuphezulu, kwanamhlanje. Ukukhanyisa iiphaneli ezikhanyayo kunye nokudala imiqondiso ethambileyo ekhanyayo, ukungabikho kwe-COB kwamanqaku abonakalayo kukhokelela ekugqibeleni okuphezulu. Nangona kunjalo, ukuba kufuneka utshintsho lombala okanye ulawulo oluchanekileyo lwe-pixel, i-COB isenokungabi yeyona ifanelekileyo ngaphandle kokuba kusetyenziswe iindlela ezikhethekileyo.

Iikhrayitheriya zokukhetha ezisebenzayo ziquka umgangatho wombala, iimfuno ze-lumen, umgama wokubukela, iimeko zokusingqongileyo, kunye nokufikeleleka kokugcinwa. Kwiindawo apho abantu baya kuba kufutshane nomcu—njengaphantsi kweekhabhathi zasekhitshini okanye iziboniso zemyuziyam—ukuphuma okuthambileyo kwe-COB kunciphisa ukukhanya kwaye kudala ukukhanya okukhululekileyo. Kwiindawo ezinkulu ezivulekileyo okanye ukufakelwa okufuneka kukhanye kumgama omde, imicu ye-SMD enoxinano oluphezulu eneelensi ezifanelekileyo kunye nee-reflectors inokuba yinto engcono. Ukuqwalaselwa kokufakwa kunye nokubekwa komqhubi kubalulekile: qinisekisa indawo eyaneleyo yeeprofayili ze-aluminium kunye nomoya owaneleyo womoya ukuze kuthintelwe iingxaki zobushushu, kwaye ukhethe abaqhubi abaneempawu ezifanelekileyo zokufiphala kunye nokukhusela.

Ibhajethi kunye nomjikelo wobomi nazo zidlala indima. Ii-SMD strips zinokuba nexabiso eliphantsi kwiindlela ezininzi zokusebenza eziqhelekileyo kwaye zinokuba nexabiso eliphantsi ukuzitshintsha kwiindlela zokuseta ezimiselweyo. Ii-COB strips, ingakumbi ii-variants ezikumgangatho ophezulu, zingabiza kakhulu ekuqaleni kodwa zinokubonelela ngexabiso eliphezulu lobuhle kwiindlela zokufakela ezikumgangatho ophezulu. Jonga iindleko zizonke zobunini—kuquka ukusebenza kakuhle komqhubi, ukusetyenziswa kwamandla, umsebenzi wokufakela, kunye nokugcinwa okulindelekileyo—kunokugxila kuphela kwiindleko zangaphambili.

Okokugqibela, xa uchaza nayiphi na iteknoloji, cela amaphepha edatha aneenkcukacha kunye nedatha ye-photometric yehlabathi lokwenyani kubavelisi. Khangela amaxabiso e-CRI, iziphumo zovavanyo lwe-LM79 okanye lwe-LM80, amaqondo obushushu acetyiswayo okusebenza, ukulinganiswa kwe-IP kokusetyenziswa ngaphandle, kunye neendlela zokufakela ezicetyiswayo. Xa kunokwenzeka, vavanya isampuli kwindawo ukuze uvavanye ukuhambelana kombala kunye nokufana phantsi kweemeko zokujonga zokwenyani. Ucwangciso olucingisisiweyo kunye nengqwalasela kwiimfuno zombane, ubushushu, kunye nobuhle kuya kuqinisekisa ukuba iteknoloji yestrip ekhethiweyo inika iziphumo ezibonakalayo nezisebenzayo ezicetywayo.

Ngamafutshane, eli nqaku lihlolisise umahluko ophambili phakathi kweetekhnoloji ezimbini ze-LED strip ezisetyenziswa kakhulu, lahlola indlela ezisebenza ngayo ngokubhekiselele kumgangatho wokukhanya kunye nokufana, laza laxoxa ngemiba esebenzayo yoyilo, ulawulo lobushushu, ukusebenza kakuhle, kunye nezicelo zehlabathi lokwenyani. Zombini ezi teknoloji zibonelela ngeenzuzo ezibalulekileyo, kwaye ukhetho olufanelekileyo luxhomekeke kwizinto ozibeka phambili—nokuba zimbonakalo engenamthungo, ukuguquguquka kombala, ukulula kokufakwa, okanye ukusebenza kwamandla ixesha elide.

Njengomzekelo wokugqibela, vavanye iprojekthi yakho ngokupheleleyo: cinga ngomgama wokubukela kunye neenjongo zobuhle, fanisa imveliso ye-lumen nomsebenzi, ubeke phambili ubushushu obufanelekileyo kunye nabaqhubi abasemgangathweni, kwaye ucwangcise ukufikeleleka kunye nexesha elide.
