LED matrix: hauj lwm, daim ntawv thov

LED matrix nruab nrab yog tag nrho ob qho neeg LEDs los yog LED rooj sib txoos, ua rau ib pab pawg neeg ntawm muaju. Tej matrices tau pom heev lug siv nyob rau hauv kev teeb pom kev zoo systems thiab thaj chaw, txoj kev thiab tsev facades, thiab siv lawv rau tus kheej sab hauv tsev teeb pom kev zoo, piv txwv li, nyob rau hauv lub spotlights. LED matrix yuav muab, nyob ntawm seb lub hom phiaj, raws li ib tug directional teeb flux, thiab diffused.

Qhov yuav tsum tau mus kawm tus txheej txheem ntawm kev txuas cov LED muaj hwj huam lug, raws li zoo raws li txuam nrog cov txheej txheem tsim thiab technology teeb meem tam sim no tshwm sim los ntawm lub loj hlob sai muaj koob meej ntawm cov khoom, thiab, ntawm chav kawm, tus ntawm no qauv nyob rau hauv lub teeb pom kev zoo kev lag luam. Yog vim li cas rau xws li ib tug loj feem yog ib tug xov tooj ntawm cov kev pab uas muaj tau tiav raws li ib tug tshwm sim ntawm kev hloov ntawm fluorescent, lub tshuab nqus tsev, roj-paug qhov chaw ntawm insolation teeb niaj hnub semiconductor pab kiag li lawm. Twb yog tsis muaj daim card uas siv cov super-power diodes yuav tshuam txo tus nqi ntawm lub zog noj, raws li tau zoo raws li rau kom cov theem ntawm kev ntseeg, durability thiab tej friendliness ntawm lub teeb qhov chaw.

Vim mus rau saum toj zoo, txoj kev loj hlob thiab zus tau tej cov tseeb technologies nyob rau hauv lub teb ntawm LED khoom hnub no yog nqa tawm sai heev. Cov uas yuav tsum tau rau qhov zoo ntawm dispersion ntawm lub txim liab luminous flux, luminous hwj chim semiconductor LEDs tas li nce, thiab qhov no txhais tau tias lub zog xav tau thiab rau matrices.

LED matrix nruab nrab yog ib pab pawg neeg ntawm muaju muaj los ntawm lub mixed ntsiab cai - series-thaum uas tig mus. Tus nqi ntawm voltage thiab tam sim no nyob rau hauv lub LED matrixes me ntsis ntau tshaj li qhov voltage thiab tam sim no nyob rau ntawm lub zoo tib yam LEDs. Qhov no yog vim lub fact tias cov muaj pes tsawg leeg ntawm lub matrix muaj xws li ib pab pawg neeg ntawm semiconductor ntsiab. Rau zoo long-term lub lag luam thiab cov LED array nws yuav tsum tau nruab nrog ib tug haib thiab ruaj khov DC fais fab qhov chaw (los yog hwj chim qhov twg los thiab tus neeg tsav tsheb), thiab lub tshav kub tog. Feem ntau cov feem ntau nyob rau hauv lub luag hauj lwm ntawm ib tug kub tog yog siv txhuas los yog tooj liab heatsink.

Xyaum qhia tau hais tias nyob rau hauv peb hnub tag nrho cov ntau thiab ntau nrov high-power LED array. Tom qab tag nrho, cov khoom uas yog tau tso cai rau yuav luag txo tau tus nqi ntawm high-power teeb tsim los ntawm ua ke ob peb daim rau ib tug. Tej lub koom haum tau tso cai manufacturers xwb tsis txo tau tus nqi ntawm zus tau tej cov teeb pom kev zoo fixtures, tab sis muaj nuj nqis txhim kho lawv zoo. Qhov no yog vim hais tias cov LED matrix Circuit Court yog significantly txo, thiab cov zauv circuitry, ces nws yog kev ruaj ntseg.

Ib qho tseem ceeb parameter ntawm tej LED array yog lub luminous efficiency. Nws nyob rau ntawm qhov zoo tshaj ntawm lub teeb muaju. Txawm li cas los, nws yuav tsum tau to taub hais tias txawm nrog rau daim ntawv thov ntawm qib muaju, lub teeb tso zis ntawm lub matrix yuav me ntsis qis dua lub zuag qhia tag nrho tawm los ntawm muaju muaj nyob rau hauv tus tsim. Qhov no yog vim cov nyhuv ntawm blending (kev sib nrig sib haum) ntawm lub teeb, lub diodes teem nyob rau hauv lub tam sim ntawd cheeb tsam.
