Chii Chiri Nheyo yeRuvara rweMarambi eMarambi Bead?

Iro zita rakazara re LED is semiconductor emitting diode, iyo yakagadzirwa semiconductor zvinhu. Basa rayo rinoshanda nderokushandura zvakananga simba remagetsi kumagetsi emagetsi, uye nhamba yemagetsi inoshandurwa kuva chiedza chechiedza chechiedza -emitting device. Zvayakanakira ndezvekuti: kuderera kwekushandisa, kupenya kwakanyanya, ruvara rwakapfuma, kusimba kwakasimba kwekudengenyeka, hupenyu hurefu hwesevhisi (kupenya kwakajairika kunosvika maawa 80,000 kusvika ku100,000), mwenje unotonhora sosi, nezvimwewo, inogona kunzi ndeyechokwadi girini mwenje. Zvigadzirwa zvekuvhenekesa zvine LED semwenje mutsva zvichatsiva marambi machena ekuruka mune ramangwana rezana ramakore rechi21, richiva imwe shanduko mukuvhenekera kwevanhu. Mabheji emwenje e LED anoshandisa yakaderera-voltage magetsi, uye magetsi emagetsi anochengetwa pakati pe2-4V. Maererano nekusiyana kwechigadzirwa, mabheji emwenje e LED ane simba repamusoro-voltage pane kushandiswa kwesimba guru-voltage, iro rinonyanya kukodzera kushandiswa munzvimbo dzevanhu munzvimbo dzevanhu. Kuumbwa kwemavara emarambi emwenje e LED anosanganisira tsvuku (R), girini (g), uye bhuruu (b) matatu -base color LED. Wese munhu anoziva maviri-mavara LED. Kazhinji inosanganisira mwenje dzvuku LED uye girini LED. Inogona kuzvimiririra kubudisa chiedza chitsvuku kana chegirini. Kana mwenje dzvuku uye mwenje wegirinhi zviri maratidziro panguva imwe chete, iwo maviri marudzi echiedza chetsvuku uye girinhi anozosanganiswa kuita orenji -yero. Nheyo yekusandura kwerambi rekubvisa ruvara ndeye apo matatu ekutanga ma LED anovhenekera aine maviri maLED, anogona kuburitsa yero, yepepuru, cyan (senge matsvuku uye ebhuruu maLEDs pakuvheneka kunze kwechiedza chepepuru); Kana ma LED matatu echiedza chebhuruu panguva imwe chete, anobudisa chiedza chichena. Kana paine dunhu rinogona kuvheneka dzvuku, girini, uye bhuruu mwenje we LED zvichiteerana, kuvheneka kumusoro, uye kuvhenekerwa nemavara matatu ega ega, ipapo mavara manomwe akasiyana echiedza anogona kuburitswa, saka chiitiko chemavara emwenje e LED anooneka.
