Chimiro uye hunhu hwemarambi e LED mabheji anonyanya kusanganisira machipisi e LED, zvinhu zvekurongedza, zvinotungamira, conductive zvinhu uye mwenje-kutumira zvinhu.
1. Chipu che LED: Chikamu chepakati chemwenje ye LED mabheji ndeye LED chip, iyo yakagadzirwa semiconductor zvinhu. LED machipisi anowanzo kuumbwa neP-mhando uye N-mhando semiconductor zvinhu. Kana yapiwa simba, PN junction inoumbwa pakati peP-type neN-type. Charge recombination inowanikwa nekupinza maerekitironi nemakomba, zvichikonzera photoelectric effect.
2. Encapsulation zvinhu: LED chips dzinoda kuchengetedzwa ne encapsulation zvinhu. Kazhinji encapsulation zvinhu zvinosanganisira epoxy resin, porcelain glue, silica gel, nezvimwewo. Iyo yekurongedza zvinhu inogona kupa dziviriro uye kugadzirisa kweiyo chip, uye ine zvimwe zvinopisa zvinopisa uye zvinodzivirira kupisa.
3. Inotungamira: Chipu che LED chinoda kubatanidzwa kubhodhi redunhu, uye vatungamiri vanoita basa rekutumira uye kutumira zviratidzo zvemagetsi. Zvishandiso zvinotungamirira zvinozivikanwa zvinosanganisira waya yegoridhe uye waya yemhangura. Waya yegoridhe ine yakanaka conductivity yemagetsi uye kusagadzikana nekuora.
4. Conductive zvinhu: mwenje we LED mabhesi anoda kuendesa masaini emagetsi kune chip kuburikidza ne conductive zvinhu. Conductive zvinhu zvinowanzoita simbi, senge sirivheri, mhangura kana aruminiyamu, ine yakanaka conductivity yemagetsi uye kusagadzikana kwekuora.
5. Translucent zvinhu: mwenje we LED mabhedhi anoda translucent zvinhu kuti uwane kubuda kwechiedza. Zvakajairika translucent zvinhu zvinosanganisira epurasitiki uye girazi. Zvishandiso zvinofambisa mwenje zvinoda kuve nemwenje wakanaka wekufambisa uye UV kuramba kuti uve nechokwadi chekubuda uye kunaka kwechiedza.
Hunhu hwemwenje mwenje we LED zvinosanganisira:
1. Kushanda kwepamusoro uye kuchengetedza simba: Mabheji emwenje e LED ane high photoelectric conversion performance. Kuenzaniswa nemagetsi echinyakare masosi, LED ine yakaderera simba rekushandisa, iyo inogona kuchengetedza simba uye kuderedza kushandiswa kwesimba.
2. Hupenyu hurefu: Mabhero emwenje e LED ane hupenyu hurefu, kazhinji anosvika makumi ezviuru zvemaawa, anodarika kure kunobva mwenje wekare.
3. Kugadziriswa kwakanaka: Mabheji emwenje e LED anogona kuve akagadziridzwa ruvara maererano nezvinodiwa, uye anogona kuwana akasiyana emhando tembiricha uye kupenya kushanduka.
4. Miniaturization uye kuiswa kwakakodzera: Mabheji emwenje e LED madiki muhukuru uye akabatana muchimiro, uye anogona kuiswa nyore uye kuiswa kunze.
5. Kuramba kwakasimba kwekudengenyeka kwenyika: Mabheji emwenje e LED ane kusagadzikana kwekudengenyeka kwenyika uye haakuvadzi nyore.
6. Kushamwaridzana kwezvakatipoteredza uye kusina kusvibiswa: Mabheji emwenje e LED haana zvinhu zvinokuvadza zvakadai se mercury, zvinoenderana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza, uye hazvizobudisi kusvibiswa panguva yekushandiswa.
Kupfupisa, mabheji emwenje e LED ane hunhu hwepamusoro-soro, kuchengetedza simba, hupenyu hurefu, kuchinjika kwakasimba, kuchengetedzwa kwezvakatipoteredza uye kusvibiswa-kusina kusvibiswa, saka anoshandiswa zvakanyanya mukuvhenekesa, kuratidza, kushongedza kwemukati uye zvigadzirwa zvemagetsi nemimwe minda.
Zvese mune zvese, tekinoroji ye LED inoshanda zvakanyanya maererano nekushandiswa kwesimba, hupenyu hurefu, kubuda kwechiedza uye kudzoreka. Simba rayo rakaderera kushandisa, hupenyu hurefu, kubuda kwechiedza chepamusoro uye kushanda-pakarepo kunoita kuti ive sarudzo yakanakisa yekuvhenekesa kana ichienzaniswa neyekare incandescent uye mwenje wefluorescent. Sezvo kudiwa kwemagetsi ekuchengetedza uye ane hushamwari mwenje mhinduro kuri kuramba kuchikura, tekinoroji yeLED inotarisirwa kuita basa rinowedzera kukosha mukuumba ramangwana remwenje.
