Luminous Diode 3535 Chiziviso Chekushandisa

3535 mwenje mabheji LED mwenje mabhero ane rakasiyana mukana, asi LED mwenje mabhero ari panjodzi semiconductor chigadzirwa, saka tinofanira kungwarira pakushandisa LED zvigadzirwa. Iye zvino tichapfupisa mamwe ekudzivirira kwekushandisa kwe LED. Ndapota isa kukosha kukuru kwairi. (1) Magetsi anofanirwa kushandiswa muDC magetsi. Vamwe vagadziri vevagadziri vanofanirwa kushandiswa kuitira kuderedza mutengo wezvigadzirwa. “Kurwisa ”Simba pane zvigadzirwa zve LED nenzira, izvo zvinokanganisa zvakananga hupenyu hwezvigadzirwa zvemwenje zve LED. Kutora yakakosha yekuchinja magetsi (ichida inogara ichiyerera sosi) chigadzirwa chinopihwa kune mwenje we LED mabhedhi zvigadzirwa hazvikanganise hupenyu hwesevhisi yechigadzirwa, asi mutengo wechigadzirwa wakakwirisa. (2) Anti-electrostatic matanho anofanirwa kutorwa mukugadzirisa uye kugadzirwa kwemarambi e LED. Magirovhosi, nezvimwewo, avo vane mamiriro vanogona kuisirwa ne-anti-static ion mafeni, uye zvakare ive nechokwadi chekunyorova kwewekishopu kunosvika makumi matanhatu neshanu muzana, kuitira kudzivirira mhepo kubva pakuoma zvakanyanya kugadzira magetsi akamira, kunyanya girini. Mabheji emwenje e LED ari nyore kukuvadzwa nekukuvara kwemagetsi. Uye zvakare, akasiyana mhando -giredhi LED anti -static masimba zvakare akasiyana. Mabhengi emwenje e LED ane giredhi remhando yepamusoro anofanira kunge akasimba. Panogona kunge paine shamwari dzakawanda dzisingazive magetsi akamira zvakanaka. Ini ndichasuma ruzivo rwemagetsi akadzikama mune zvakadzama pano: musimboti wemagetsi akamira ndiyo yakasara mutero. Charge ndiyo huwandu hwemuviri hwese essence ye static magetsi. Chirungu chinonzi ESD. Huwandu hunoenderana nezvinogoneka, munda wemagetsi, zvazvino, nezvimwe. iwo ese huwandu hwemuviri hunokonzerwa nekuvapo kwechaji kana kufamba kwechaji. Matambudziko mazhinji emagetsi anokonzerwa nevanhu vasina ESD kuziva. Kunyangwe ikozvino, vanhu vazhinji vanofungidzira kuti ESD ichakonzera kukuvadza kune zvigadzirwa zvemagetsi. Izvi zvinodaro nekuti kukuvara kwakawanda kweESD kunoitika pazasi pekunzwa kwemunhu, nekuti muviri wemunhu unoonekwa voltage ye static discharge inenge 3KV, uye akawanda emagetsi emagetsi achakuvadzwa kana ari mazana emavolts kana akawanda mavolts. Kazhinji, kana zvigadzirwa zvemagetsi zvakakuvadzwa neESD Hapana muganhu wakajeka, uye chikamu chacho chakaiswa paPCB chisati chaonekwa. Somugumisiro, kune matambudziko akawanda, uye kuongorora kwakaoma. Kunyanya kukuvadzwa kunogona kuitika, zvakaoma kuyera kuita kwekuita kwayo kunyangwe nezviridzwa zvine hunyanzvi, saka vese mainjiniya emagetsi nevagadziri vakafungidzira ESD. Mumakore achangopfuura, kuedza kwakaratidza kuti izvi zvinogona kukanganisa zvichava Kuvimbika kunoderera zvakanyanya. (3) Iyo tembiricha yemwenje ye LED mabheji inofanirwa kutarisisa kuwedzera kwekushisa kuchaita kuti kupikisa kwemukati kwemarambi e LED kuve kudiki. Mushure mekunge tembiricha yezvakatipoteredza yekunze ichiwedzera, kupikisa kwemukati kwemarambi e LED kunoderedzwa. Ikozvino inosimuka, kana ikozvino kushanda ikozvino kudarika basa rayo rakarongwa, inokanganisa hupenyu hwebasa rezvigadzirwa zve LED, izvo zvichange zvichikonzerwa zvakanyanya nemarambi e LED. “Kupiswa ”Naizvozvo, zvakanakisa kushandisa Hengli sosi magetsi ekupa kuti ive nechokwadi chekuti kushanda ikozvino kwe LED hakukanganiswe nekunze tembiricha. Iyo tembiricha yemwenje ye LED mabhedhi zvakare ndiyo inonyanya kukosha inokanganisa hupenyu hwe LED. Tapota ngwariro yacho. (4) Kuiswa chisimbiso chezvigadzirwa zvemwenje we LED, zvisinei nemwenje we LED bead chigadzirwa, chero bedzi ichiiswa kune kunze, iri kutarisana nedambudziko rekusapinda kwemvura uye hunyoro-uchapupu hwekuvhara matambudziko. Kana ikasabatwa zvakanaka, inokanganisa zvakananga hupenyu hwebasa rezvigadzirwa zve LED. Ikozvino kune vashoma vagadziri vane yakakwira chigadzirwa mhando zvinodiwa vanotora yechinyakare epoxy resin “Mvura ”Iyo nzira ndeyekuvhara zvigadzirwa zve LED. Iyi nzira inonyanya kunetsa kushanda. Iyo haina kunyatsokodzera ma LED mabhedhi zvigadzirwa zvine vhoriyamu yakakura, uye zvakare inowedzera huremu hwechigadzirwa. (5) Ikozvino yemarambi emwenje e LED haigone kudarika iyo IF ikozvino yemabheji emwenje e LED. (6) Mabheji emwenje e LED anofanirwa kutarisisa mabheji emwenje e LED haafanire kunge ari padyo necolloid kana kona kana kona yakakotama. Inofanira kuchengetwa kure neanopfuura 2mm kubva kune colloid. Nhamba yekupeta panzvimbo yacho haigoni kudarika katatu, uye kona yakanyura mukati 90 °Dzokera kunzvimbo yepakutanga kamwe chete. (7) Kupisa kwekushisa kwekushisa kwewelding inenge 260 C, nguva inodzorwa mukati me5s, uye nzvimbo yekugadzira iri pamusoro pe2.5mm kubva pasi pecolloid.
