Matrix LED: inkcazelo, isicelo

matrix LED imele zombini ii-LED ngamnye okanye ibandla LED, senziwe iqela ziikristale. matrices ezinjalo baye bafumana kakhulu ngokubanzi kusetyenziswa kwiinkqubo zokukhanyisa jikelele kunye izakhiwo, iindlela kunye nezakhiwo olungaphambili, kwaye uzisebenzise ukukhanyisa endlwini yakho, umzekelo, kwi spotlight. LED matrix angakhupha, kuxhomekeke injongo, njengoko zemiyalelo ukubhobhoza ukukhanya, kwaye udlulele.

Imfuneko ukufunda inkqubo odibanisa izakhiwo amandla eliphezulu LED, kwakunye ezinxulumene iingxaki ngoyilo kunye nobuchwepheshe ngoku ezibangelwa ukuthandwa ezikhula ngokukhawuleza ezi mveliso, yaye, ke, impembelelo yalo mkhwa kwishishini zokukhanya. Isizathu sokuba ifuthe elikhulu enjalo eziliqela izibonelelo ezithe zafumana ngenxa ukutshintshwa ezijiko-jiko, lwepolitiki, igesi-nokukhululwa umthombo elihlala livelile ukukhanya izixhobo semiconductor mihla. Sele ke akukho mfihlakalo ukuba ukusetyenziswa ilight super-kungaba kakhulu ukunciphisa umlinganiselo wamandla osetyenzisiweyo, kwakunye nokwandisa umgangatho kukuthembeka, iyahlala ukhathalelo lwendalo zemithombo ukukhanya.

Ngenxa iingenelo ngentla, uphuhliso kunye nokuveliswa iiteknoloji ezintsha kwi entsimini kwezixhobo LED namhlanje wenziwe ngokukhawuleza. Iimfuno kuba umgangatho kwiintsali wobhobhozayo ezikhanyayo ukhutshiwe, ezikhanyayo LED amandla semiconductor ziyanda rhoqo, kwaye oku kuthetha ukuba Iimfuno ezongezelekileyo kunye matrices.

matrix LED imele iqela ziikristale ingabandakanywa umgaqo exutyiweyo - series-ngaxeshanye. Ixabiso ombane kunye ezikhoyo matrixes LED engaphezulwana nje kancinane kune ombane kwaye ngoku LED zesiqhelo. Oku kungenxa yokuba ukwakhiwa isizalo uquka iqela lweziqalelo semiconductor. Kuba ukusebenza ixesha elide olusebenzayo kwaye uluhlu LED kufuneka mayixhotyiswe DC umthombo onamandla nozinzileyo amandla (okanye umthombo wamandla kunye nomqhubi), kunye esinkini nobushushu. Ngokufuthi indima isinki ubushushu kusetyenziswa i-alumuniyam okanye heatsink ubhedu.

Practice ibonisa imihla yethu yonke ngakumbi zithandwa kakhulu eliphezulu-amandla LED uluhlu. Ngapha koko, ezi mveliso bavumelekile ukuba ukunciphisa kakhulu ixabiso yoyilo isibane ophezulu-amandla ngokuhlanganisa chips eziliqela omnye. Unxulumano olunjalo uye wavumela abenzi ukunciphisa kuphela iindleko zokuvelisa ngezinto izibane, kodwa kakhulu ukuphucula umgangatho wabo. Oku kungenxa yokuba wesekethe matrix LED yehliswe kakhulu, kwaye busebenze elula, ngoko ke ekhuselekileyo.

I parameter ebalulekileyo naluphi na uluhlu LED yi ukusebenza ezikhanyayo. Kuya kuxhomekeka kumgangatho ziikristale ukukhanya. Noko ke, kufuneka kuqondwe ukuba nkqu kunye nesicelo ziikristale eziphakamileyo kwibakala, ukuba imveliso Ukukhanya matrix kuya kuba ngaphantsi ngandlel ngaphezu isivuno iyonke ziikristale ifakiwe kuyilo. Oku kungenxa nefuthe lwe alpha (ukufakwa efanayo) ukukhanya, le ilight zicwangciswe kufutshane.
