Yepamberi nhoroondo yekupenya kwemwenje ye LED uye mwenje unoshanda

Muna 2006, CREE yakazivisa kuvhurwa kweiyo nyowani inotonhorera chena LED, "XP.G”, iyo inoisa zvinyorwa zvitsva mukupenya kwakanaka uye kupenya.Kana iyo yekutyaira ikozvino iri 350 mA, inopenya inopenya inosvika 139 lm, uye inopenya inoshanda iri 1 kusvika lm/W.Kupenya uye kupenya kwakanaka kwakateerana 37% uye 53% yakakwirira kupfuura yeCree inopenya XR.ELED, iyo inonzi "iyo indasitiri inopenya uye yepamusoro-inoshanda yekuvhenekesa LED".

Muna 2007, Nichia akaburitsa rudzi rutsva rwe LED.Chigadzirwa chekuyedza chine kupenya kunopenya kunosvika 145 m pasi pemamiriro ekumberi ikozvino kwe350 mA, inopenya inopenya ingangoita 134 lm/w, chip saizi ye1 m.㎡, uye tembiricha yeruvara ye4 988K (mune Ir = 20 mA) , Iyo inopenya inopenya yakakwira se1 69 lm / W).

Muna 2007, kambani yeAmerican CREE yakakura kaviri heterojunction paSIC substrate, uye michina yakagadzirwa zvakare yakanaka.Iyo SiC substrate inogona kugadzira simbi electrode yeGabl-yakavakirwa LED pazasi peiyo substrate, uye yazvino inogona kuyerera yakatwasuka kuburikidza yakaderera-resistance conductive substrate, iyo zvakare inoisa hwaro hwekuvandudza kweimwe optoelectronic zvishandiso.

Mugore rimwe chetero, Nichia akaburitsa chizvarwa chinotevera chepamusoro-simba machena ma LED.Iyo mwenje inoyerera ye350 mA ikozvino yekupinda ndeye 145lm, uye inopenya inoshanda i134lm/W.Chikonzero chekushanda kwepamusoro kwechena LED ndeyekuona kugona kwakanyanya kweblue LED chip inoshandiswa.Kana iyo yebhuruu LED ichityairwa pa350 mA, simba rekuona i651mW, wavelength iri 444nm, yekunze quantum kunyatsoita 66.5%, uye WPE i60.3%.

Mugore rimwe chetero, Nichia akaisa mukugadzirwa kwema LED machena ane kupenya kwakanaka kwe150 lm/W.Kushanda kwe LED iyi kunomiririra danho repamusoro muindasitiri panguva iyoyo, uye mhando ine kumberi ikozvino kwe20 mA i1001m/W.

Mukutanga kwa2009, CREE yakazivisa kuti yakanga yawana chiedza che 161 lm/W uye tembiricha yeruvara ye4 689K.Iwo akajairwa bvunzo mamiriro eiyi LED anoitwa pakamuri tembiricha uye drive ikozvino ye350 mA.

Pakupera kwa2009, CREE yakazivisa kuti mwenje wayo chena-yakakwirira-simba LED inopenya inopenya yakawana 1 86 lm/W.CREE mhedzisiro yebvunzo inoratidza kuti kana yakabatana ruvara tembiricha iri 4577K, iyo LED inogona kuburitsa mwenje kubuda kwe1971m.Muedzo unoitwa munzvimbo yakajairwa yekuyedza ine dhiraivha ikozvino ye350 mA pane tembiricha yekamuri.

Mukutanga kwa2009, maererano nemhedzisiro yerabhoritari yaNichia, kupenya kwe LED kwakawedzera kusvika 2491 W kuramba pa20 mA.Nekudaro, kana iri iyo 350 mA ikozvino inowanzoshandiswa muindasitiri yeLED, kupenya kwakadzika kwadzika kusvika 1451 kumira W, izvo zvamutsa kutarisisa kweindasitiri.

Muna 2011, mainjiniya eOsram's R&D akavandudza matekinoroji ese ane chekuita nekugadzira LED.Mune bvunzo dzemurabhoritari, iwo achangobva kugadzirwa machena ma LED anoisa kupenya kwekambani uye marekodhi anopenya ekushanda.Pasi pemamiriro ekushanda kwemazuva ano ye 350 mA, kupenya kwe LED kunogona kusvika ku 1 55 lm, uye kupenya kunopenya kunosvika 1 36 lm / w.Iyo chena mwenje LED prototype inoshandisa 1 m㎡chip, tembiricha yeruvara rwechiedza chakabudiswa i5000K, uye chromaticity coordinate i 0.349/0.393 (cx/cy).

Muna 2011, CREE yakazivisa kuti chena yayo yemwenje ye LED inodarika 231lm/W.Kambani yakashandisa imwe-module chikamu, uye yakayera chena LED inopenya inopenya ye23llm/W patembiricha yeruvara ye450OK uye tembiricha yekamuri yekuyedza ye350mA.Parizvino, zviratidzo zvakasiyana-siyana zve LED zvichiri mukuenderera mberi.Nekuwedzera kweminda yekushandisa, izvo zvinodikanwa zvemwenje mwenje we LED zvinopatsanurwa zvishoma nezvishoma.
