Mumakore achangopfuura,Magetsi emumugwagwa e LEDvave vachinyanya kufarirwa nekuda kwekuchengetedza kwavo simba uye kusimba. Zviedza izvi zvakagadzirirwa kuvhenekera migwagwa nenzvimbo dzekunze nechiedza chakajeka uye chakanangana. Asi wakambozvibvunza here kuti chii chiri mukati memwenje we LED? Ngatitarisei mashandire emukati meizvi zvigadziriso zvemwenje zvine hunyanzvi.
Pakutanga kuona, mwenje wemugwagwa we LED unoratidzika kunge uri nyore mwenje. Zvisinei, zvikamu zvayo zvemukati zvakanyanya kuoma. Izvo zvakakosha zvemagetsi emumugwagwa e LED zvinosanganisira machipisi e LED, madhiraivha, masingi ekupisa, uye michina yemaziso.
LED chips
LED machipisi ndiwo moyo uye mweya wemarambi emumugwagwa. Aya madiki semiconductor midziyo inopenya kana magetsi achipfuura mazviri. Tekinoroji yeLED yakashandura indasitiri yekuvhenekesa nekupa simba rakanyanya uye hupenyu hurefu. Iwo machipisi e LED anoshandiswa mumagetsi emumugwagwa anogadzirwa ne gallium nitride, chinhu chinoburitsa chakajeka, chinotungamira chiedza.
Mutyairi SPD
Mutyairi chimwe chikamu chakakosha che LED mwenje mwenje. Iyo inogadzirisa ikozvino ye LED chips, kuve nechokwadi kuti vanogamuchira chaiyo voltage uye ikozvino. Madhiraivha e LED akagadzirirwa kushandura iyo alternating ikozvino (AC) kubva pamagetsi ekuisa kune yakananga ikozvino (DC) inodiwa ne LED. Ivo zvakare vanopa akasiyana siyana ekudzora mabasa, senge dimming uye kugadzirisa kwemavara, zvichibvumira kushanduka kukuru mukugadzira mwenje uye kuchengetedza simba.
Heat sink
Kupisa kunyura kunoita basa rakakosha mukuchengetedza hupenyu hwemarambi emumugwagwa e LED. Nekuda kwekushanda kwakanyanya kwema LED machipisi, anogadzira kupisa kushoma pane echinyakare magetsi masosi. Zvisinei, kupisa kwakanyanya kunogona kuderedza hupenyu hwe LED uye kushanda. Iyo inopisa sink, inowanzo gadzirwa nealuminium, ine basa rekubvisa kupisa kwakanyanya uye kudzivirira iyo LED kubva pakupisa. Nekuve nechokwadi chekutonga kwakakwana kwekupisa, kupisa kunopisa kunowedzera kuvimbika uye kusimba kwemagetsi emumugwagwa.
Optics
Optics mu LED mwenje mwenje inodzora kugovera uye kusimba kwechiedza. Ivo vanobatsira kutungamira mwenje kubva kumachipi e LED kuenda kunzvimbo inodiwa uku ichideredza kusvibiswa kwechiedza uye kupenya. Malenzi uye maratidziro anowanzo shandiswa mukuvhenekesa mumigwagwa kuti awane chaiyo kugovera kwechiedza, kuwedzera kuvharika kwemwenje uye kugona. Optics inogonesa kurongeka kwebeam kune kunyangwe kuvhenekesa kwemigwagwa uye nzvimbo dzekunze.
Power unit
Pamusoro pezvikamu zvikuru izvi, kune zvimwe zvinotsigira zvinhu zvinobatsira mukushanda kwemwenje yemugwagwa we LED. Iyo magetsi unit ine basa rekugadzirisa nekugadzirisa simba rinopihwa kumutyairi. Inovimbisa kushanda kwakagadzikana pasinei nekupa magetsi kana kuchinja kunogona kuitika.
Dziviriro dzakavharirwa uye dzakavharirwa
Pamusoro pezvo, zvivharo zvekudzivirira uye zvakavharirwa zvinodzivirira zvinhu zvemukati kubva kune zvakatipoteredza zvakaita sehunyoro, guruva, uye tembiricha shanduko. Mwenje yemumugwagwa ye LED yakagadzirirwa kutsungirira mamiriro ekunze akaoma, kuve nechokwadi chekuita kwakavimbika kunyangwe mumamiriro akanyanya.
Mukufunga kwangu
Kufambira mberi mune tekinoroji yekuvhenekesa mumigwagwa yeLED kwakashandura nzira yatinovhenekera migwagwa yedu nenzvimbo dzekunze. Kuenzaniswa nemhinduro dzemwenje dzechinyakare, magetsi emumugwagwa e LED anogona kuchengetedza simba rakakura, nekudaro kuderedza kushandiswa kwemagetsi uye kubuda kwekabhoni. Pamusoro pezvo, hupenyu hwavo hwesevhisi hurefu hunodzikisira kudiwa kwekugara uchitsiviwa, zvichibatsira mukukosheswa kwemitengo kumadhorobha nenharaunda.
Uyezve, kutungamira kwema LED kunovimbisa kugovera kwechiedza, kuderedza kusvibiswa kwechiedza uye kuderedza kusagadzikana kune vagari. Iyi tekinoroji inoshanda yekuvhenekesa inoshandura mamiriro emudhorobha, ichipa migwagwa yakachengetedzeka, ine chiedza chakanaka kune vanofamba netsoka nevatyairi.
Muchidimbu
Mwenje yemugwagwa we LED inoumbwa nemhando dzakasiyana-siyana dzakaoma dzinoshanda pamwe chete kuti dzipe simba rinoshanda uye rakavimbika chiedza. Machipisi e LED, madhiraivha, masingi ekupisa, uye optics anosanganisa kugadzira inoshanda uye inogoneka yekuvhenekesa mhinduro. Sezvo tekinoroji yeLED ichiramba ichikura, tinogona kutarisira kune dzimwe nzira dzakasimba uye dzekuvandudza magetsi emumugwagwa mune ramangwana.
Kana iwe uchifarira marambi emumugwagwa, unogamuchirwa kubata solar led mwenje mugadziri TIANXIANG kuverenga zvimwe.
