4 Makiyi matekinoroji ekuvhenekesa kwe LED
Kusarudzwa uye kuronga kwe LED
Kune marudzi matatu makuru e LED maererano nekugadzirisa: imwe inotungamirira (lead angle) LED, iyo yakarongerwa ikozvino inowanzoita 20 mA, simba racho idiki, uye akawanda anowirirana anodiwa pakuvheneka; imwe yacho i-single-chip surface mount Chip LED, iyo yakayerwa ikozvino inowanzopfuura 50 mA (ikozvino iyo yepamusoro yakayerwa ikozvino ye LED inosvika 1000 mA), simba racho rakakura, uye rinogona kushandiswa roga; chechitatu kubatanidza akawanda madiki emagetsi machipisi kuti awane simba repamusoro, ndiko kuti, musanganiswa Power LED.
Kushandiswa kwema LED akawanda mukuwirirana kune mari shoma yekugadzira uye yakakodzera kuvhenekera-nzvimbo huru, asi inoda kurongeka kwakakodzera. Paunenge uchishandisa diode yakaderera-simba, kuitira kuti kuvhenekera kwerambi rimwe chete kuite zvinodiwa nechiso chekuchera marasha, diode dzakawanda dzinofanira kushandiswa zvakafanana. Izvi zvinounza mubvunzo wekuti ingani magetsi anoshandiswa uye maitiro ekudzora huwandu hwese hwema diode mukuwirirana uye muboka kuti asangane nezvinodiwa zvemukati akachengeteka wedunhu. Nekuda kwekuti voltage yedunhu rakachengeteka iri 24, 18, 12 V, zvichingodaro, mafungu anoenderana nezvinodiwa zvekuchengetedzwa kwemukati anofanira kunge ari 400, 600, uye 1000 mA. Kune epasi-simba akajairwa mwenje-emitting diode, iyo yekushanda mamiriro voltage anowanzo ari 3 kusvika 4 V uye inoshanda ikozvino 20 mA. Kana 18 V / 600 mA yakasarudzwa, mapoka makumi matatu anogona kubatanidzwa mune zvakafanana, 5 munhevedzano seboka, uye ipapo resistor yakakodzera inobatanidzwa munhevedzano. Kudonha kwevoltage yega yega diode isingasviki 3.6V, iyo inosangana nezvinodiwa zvemukati yakachengeteka mhando uye kupenya. Kana imwe kana boka ikakuvadzwa, haikanganisi basa remamwe diode kana kuvhenekera.
Kana ma LED akawanda akabatanidzwa mukufanana, simba re LED imwe iduku uye kupisa kunogadzirwa kunopararira. Chero bedzi ma LED akarongeka uye nzvimbo yeCu yebhodhi yakadhindwa yedunhu yakawedzerwa, zvinodiwa zvekupisa kupisa zvinogona kuzadzikiswa.
Kana ma diode emagetsi epamusoro achishandiswa, dhizaini yedunhu rakachengeteka haisisiri nyaya. Chinokosha ndechekuti marongedzero edhiodhi kuti asangane nezvido zvemarasha ekuchera chiso.
