Mabhengi e LED anomirira madhidhiyo anobudisa chiedza.
Chirevo chayo chinopenya ndechekuti iyo PN junction terminal voltage inoumba chimwe chingave chipingamupinyi, kana kumberi bias voltage yawedzerwa, iyo inogona kuvhara inodonha, uye vazhinji vanotakura munzvimbo dzeP neN vanopararira kune mumwe nemumwe. Sezvo kufamba kwerekitironi kwakakura kudarika buri rekufamba, nhamba huru yemaerekitironi ichapararira muP-region, zvichiita jekiseni revatakuri vashoma muP-region. Maerekitironi aya anosanganiswa nemaburi mubhendi revalence, uye simba rinobuda rinoburitswa sesimba rechiedza.
Maitiro ayo ndeaya anotevera:
1. Voltage: mabheji emwenje e LED anoshandisa magetsi emagetsi mashoma, magetsi emagetsi pakati pe2-4V. Maererano nemishonga yakasiyana-siyana, inotungamirirwa nemagetsi akachengeteka kupfuura magetsi emagetsi, kunyanya akakodzera nzvimbo dzevanhu.
2. Ikozvino: kushanda ikozvino 0-15mA, uye kupenya kunowedzera kupenya nekuwedzera kwezvino .
3. Kubudirira: 80% pasi pesimba rekushandisa pane mwenje weincandescent nechiedza chakafanana.
4. Kushanda: Chimwe nechimwe chikwata che LED chip ndeye 3-5mm square, saka inogona kugadzirirwa mumhando dzakasiyana-siyana dzemidziyo, uye inokodzera nharaunda inoshanduka.
5. Nguva yekupindura: Nguva yekupindura yemwenje waro incandescent ndeye millisecond level, uye iyo yemwenje ye LED i nanosecond level.
6. Kusvibiswa kwezvakatipoteredza: Hapana simbi inokuvadza mercury.
7. Rudzi: Rudzi runogona kuchinjwa nezvino, rinotungamirirwa kuburikidza nemakemikari ekugadzirisa nzira, gadzirisa bhandi chimiro uye bhendi gap rezvinyorwa, kuti uwane tsvuku, yero, girini, bhuruu, orange multi-color light. Semuenzaniso, kana yakaderera ikozvino iri tsvuku LED, nekuwedzera kwezvino, inogona kuchinja orenji, yero, uye pakupedzisira girini.
Zvikamu zvaro zvinotsanangurwa sezvizvi:
1.Kupenya
Mutengo we LED beads une chekuita nekupenya.
Kupenya kwakajairika kwemabhero ndeye 60-70 lm. Kupenya kwakawanda kwemwenje wegirobhu ndeye 80-90 lm.
Kupenya kwe1W mwenje dzvuku kazhinji 30-40 lm. Kupenya kwe1W girinhi mwenje kazhinji 60-80 lm. Kupenya kwe1W yero mwenje kazhinji 30-50 lm. Kupenya kwe1W mwenje webhuruu kazhinji 20-30 lm.
Cherechedza: 1W kupenya ndiko 60-110LM. 3W kupenya kusvika ku240LM. 5W-300W yakasanganiswa chip, ine nhevedzano / parallel package, zvakanyanya zvinoenderana nekuti yakawanda sei ikozvino, voltage.
LED lens: PMMA, PC, optical girazi, silica gel (soft silica gel, hard silica gel) uye zvimwe zvinhu zvinowanzo shandiswa kune yekutanga lens. Iyo yakakura kona, iyo yakakwirira yechiedza chekushanda. Iine diki Angle LED lens, mwenje unofanirwa kunge uri kure.
2. Wavelength
Same wavelength uye ruvara zvinoita mutengo wakakwira.
Chiedza chichena chakakamurwa kuva inodziya ruvara (ruvara tembiricha 2700-4000K), yakanaka chena (ruvara tembiricha 5500-6000K) uye kutonhora chena (ruvara tembiricha pamusoro 7000K).
Chiedza dzvuku: bhendi 600-680, iyo 620,630 inonyanya kushandiswa kumwenje mwenje uye 690 iri pedyo ne infrared.
Blu-ray: Band 430-480, iyo 460,465 ndiyo inonyanya kushandiswa kumwenje wedariro.
Chiedza cheGreen: Band 500-580, iyo 525,530 ndiyo inonyanya kushandiswa kumwenje wedariro.
3. Ruminous Angle
Maledhi ezvinangwa zvakasiyana anoburitsa mwenje pamakona akasiyana. Special luminous Angle inodhura zvakanyanya.
4. Antistatic kugona
Antistatic kugona kwe LED mwenje bead ine hupenyu hurefu, saka mutengo wakakwira. Kazhinji kupfuura 700V antistatic LED mwenje mabheji anogona kushandiswa kuvhenekesa LED.
5. Leakage current
Mwenje wemwenje we LED inzira imwe chete inopenya inopenya muviri. Kana paine reverse ikozvino, inonzi leakage, leakage ikozvino mwenje mabheji e LED ane hupenyu hupfupi uye mutengo wakaderera.
Eurborninogadzira Mwenje Wekunze muChina. Isu tinogara tichisarudza iyo inoenderana mhando maererano nemarambi uye tinoedza nepatinogona napo kuti zvigadzirwa zvive zvakakwana.
