Kutonga kana anChiedza che LEDsosi ndiyo yatinoda, isu tinowanzo shandisa nzvimbo yekubatanidza yekuyedza, tozoongorora zvinoenderana nedata rebvunzo. Iyo yakawanda yekubatanidza sphere inogona kupa anotevera matanhatu akakosha paramita: kupenya kupenya, kupenya kwemagetsi, voltage, coordination yeruvara, tembiricha yeruvara uye color rendering index (RA). (chaizvoizvo, kune mamwe akawanda ma parameter, akadai sepeak wavelength, main wavelength, dark current, CRI, etc.) nhasi tichakurukura kukosha kweaya ma parameter matanhatu kune chitubu chechiedza uye kupesvedzera kwavo.

Luminous flux: luminous flux inoreva simba remwaranzi rinogona kunzwiwa nemeso emunhu, ndiko kuti, iyo yakazara radiation simba rinoburitswa ne LED, unit: lumen (LM). Luminous flux ndiyo yakananga kuyerwa huwandu uye yakanyanya intuitive huwandu hwemuviri kutongakupenya kwe LED.

Voltage: voltage ndiyo inogona mutsauko pakati peiyo yakanaka uye yakaipa electrodes yeMwenje we LED mabhedhi, inova chiyero chakananga, chikwata: volts (V). Izvo zvinoenderana neiyo voltage level yechip inoshandiswa ne LED.

Kubwinya kunoshanda: kupenya kwakanaka, kureva chiyero cheiyo yakazara inopenya flux inoburitswa nemwenje sosi kune yakazara simba rekuisa, ndiyo yakaverengerwa huwandu, unit: LM / W. Kune maLED, simba rekuisa rinonyanya kushandiswa kuburitsa chiedza uye kupisa. generation. Kana chiedza chechiedza chakakwirira, zvinoreva kuti kune zvikamu zvishomanana zvinoshandiswa pakupisa chizvarwa, izvo zvakare kuratidzwa kwekunaka kwekupisa kupisa.

Hazvina kuoma kuona hukama pakati pezvinoreva zvitatu zviri pamusoro. Kana kushandiswa kwazvino kwatemwa, mwenje we LED unonyatso kutsanangurwa neinopenya flux uye voltage. Kana iyo luminous flux yakakwira uye voltage yakaderera, mwenje unoshanda wakakwira. Kana iri yezvino hombe-yeblue chip yakavharwa neyero yegirini fluorescence, sezvo imwechete yepakati voltage yeblue chip inowanzotenderedza 3V, inova kukosha kwakadzikama, kuvandudzwa kwechiedza chechiedza kunonyanya kuenderana nekuvandudzwa kweinopenya flux.

Colour coordinate: kurongeka kweruvara, ndiko kuti, chinzvimbo cheruvara mu chromaticity diagram, inova kuyerwa kwehuwandu. Mune inowanzo shandiswa CIE1931 yakajairwa colorimetric system, marongero anomiririrwa neX uye Y kukosha. Iko kukosha kwe x kunogona kutariswa sechiyero chemwenje dzvuku muspectrum, uye kukosha y kunoonekwa sedhigirii rechiedza chegirinhi.

Colour temperature: huwandu hwemuviri hunoyera ruvara rwechiedza. Kana mwaranzi yeabsolute blackbody pamwe nemwaranzi yechiedza munzvimbo inooneka zvafanana, tembiricha yemunhu mutema inodaidzwa kuti tembiricha yeruvara rwechiedza. Tembiricha yeruvara ihuwandu hwakayerwa, asi hunogona kuverengerwa nemavara anoronga.

Colour rendering index (RA): rinoshandiswa kutsanangura kugona kwechiedza kudzorera ruvara rwechinhu. Inotsanangurwa nekuenzanisa chitarisiko cheruvara rwechinhu pasi pechiedza chakajairwa. Ruvara rwedu rendering indekisi indekisi chaiyo ivhareji yakaverengerwa nenzvimbo yekubatanidza yezviyero zvisere zveruvara grey tsvuku, rima grey yero, yakazara yero yegirini, yepakati yero yegirini, yebhuruu girinhi, bhuruu, yepepuru bhuruu uye chiedza chitsvuku. pepuru. Inogona kuwanikwa kuti haisanganisi yakatsvuka yakatsvuka, kureva, R9. Sezvo kumwe kuvhenekera kunoda mwenje mutsvuku (senge nyama yekuvhenekesa), R9 inowanzoshandiswa seyakakosha parameter yekuongorora maLED.

Iyo tembiricha yemavara inogona kuverengerwa neakarongedzerwa mavara, asi kana iwe wakanyatso tarisisa chromaticity chati, iwe uchaona kuti yakafanana tembiricha yemavara inogona kuenderana neakawanda mapeji emarongedzero eruvara, nepo peya yemavara coordinates inongoenderana nekudziya kweruvara rumwe chete. Nokudaro, zvakanyatsorurama kushandisa mavara ekubatanidza kutsanangura ruvara rwechiedza. Iyo indekisi yekuratidzira pachayo haina chekuita neiyo color coordinate uye tembiricha yemavara. Zvisinei, kana tembiricha yeruvara yakwira uye ruvara rwechiedza rukatonhora, chikamu dzvuku mumwenje sosi ishoma, uye indekisi yekuratidzira inonetsa kuve yakakwira zvakanyanya. Kune inodziya mwenje sosi ine yakaderera ruvara tembiricha, iyo tsvuku chikamu chakawanda, iyo spectrum yekuvhara yakafara, uye spectrum iri padyo nechiedza chechisikigo, iyo index yemavara inogona kuve yakakwira. Ichi zvakare chikonzero nei ma LED ari pamusoro pe95ra pamusika aine tembiricha yakaderera yemavara.
