Kutonga kana anChiedza che LEDsosi ndiyo yatinoda, isu tinowanzo shandisa sphere yekubatanidza kuyedza, tozoongorora data rebvunzo. Iyo yakawanda yekubatanidza sphere inogona kupa anotevera matanhatu akakosha ma paramita: kupenya kupenya, kupenya kwemagetsi, voltage, coordination yeruvara, tembiricha yeruvara, uye mavara ekupa index (Ra). (Chaizvoizvo, kune mamwe akawanda maparameter, akadai sepeak wavelength, dominant wavelength, dark current, CRI, etc.) Nhasi, ngatikurukurei kukosha kwezviyero zvitanhatu izvi zvemwenje manyuko nemhedzisiro yawo.

Ruminous flux: Ruminous flux inoreva simba remwaranzi rinogona kunzwiwa neziso remunhu, kureva, iro rakazara remwaranzi simba rinoburitswa ne LED, mulumens (lm). Luminous flux chiyero chakananga uye yakanyanya intuitive yemuviri huwandu kutonga kupenya kwe LED.

Voltage:Iyo voltage ndiyo inogona mutsauko pakati peiyo yakanaka uye yakaipa matanda eiyoMwenje we LEDbead, inova kuyerwa kwakananga, mumavolts (V). Inoenderana nevoltage yechip inoshandiswa ne LED.

Kupenya kwakanaka:kupenya kwakanaka, kureva kuti, reshiyo yezvose zvinopenya zvinobuda nechiedza kusimba rose rekuisa, ndiyo chiyero chakaverengerwa, mu lm/W. Kune LED, iyo yekuisa simba remagetsi rinonyanya kushandiswa kuvhenekesa nekudziya. Kubwinya kwepamusoro kunoratidza kuti kune zvikamu zvishomanana zvinoshandiswa pakupisa, izvo zvinoratidzirawo kunaka kwekupisa kupisa.

Zviri nyore kuona hukama pakati pevatatu vari pamusoro. Kana iyo yazvino yatemwa, kupenya kwe LED kunotemerwa neinopenya flux uye voltage.High luminous fluxuye yakaderera voltage inotungamira kune yakakwira inopenya kushanda zvakanaka. Nezvezvino hombe-yeblue chip yakaputirwa neyero yegirini fluorescence, nekuti imwechete yepakati voltage yeblue chip inowanzoita 3V, inova kukosha kwakadzikama, kuvandudza kushanda kwemwenje kunonyanya kuenderana nekuwedzera kupenya kunopenya.

Colour coordinate:kurongeka kweruvara, ndiko kuti, nzvimbo yeruvara mudhayagiramu yechromaticity, ndiko kuyerwa kwehuwandu. Mune inowanzo shandiswa CIE1931 yakajairwa colorimetric system, marongero anomiririrwa ne x uye y kukosha. Iko kukosha kwe x kunogona kutariswa sechiyero chemwenje dzvuku muspectrum, uye kukosha y kunoonekwa sedhigirii rechiedza chegirinhi.

Tembiricha yemavara:huwandu hwemuviri hupima ruvara rwechiedza. Kana mwaranzi yemuviri mutema chaiwo wakanyatsofanana nemwaranzi yechiedza munzvimbo inooneka, tembiricha yemuviri mutema inodaidzwa kuti tembiricha yeruvara rwechiedza. Tembiricha yeruvara ndeye kuyerwa kwehuwandu, asi inogona kuverengerwa nemavara coordinates panguva imwe chete.

Indekisi yekupa mavara (Ra):rinoshandiswa kutsanangura kugona kudzoreredza kwechiedza paruvara rwechinhu. Inotaridzirwa nekuenzanisa ruvara rwezvinhu pasi pechiedza chemazuva ose. Ruvara rwedu rendering indekisi iavhareji yezviyero zvisere zveruvara rwechiedza zvakaverengerwa nechikamu chekubatanidza chegrey dzvuku, rima grey yero, yakazara yero yegirini, yepakati yero yegirini, yebhuruu yebhuruu, yebhuruu, yepepuru, uye yepepuru yakatsvuka. . Inogona kuwanikwa kuti haisanganisire yakatsvuka, iyo inowanzozivikanwa seR9. Nekuti kumwe kuvhenekesa kunoda mamwe mwenje mutsvuku (senge nyama yekuvhenekesa), R9 inowanzoshandiswa seyakakosha parameter yekuongorora LED.

Iyo tembiricha yemavara inogona kuverengerwa nemavara coordinates. Nekudaro, kana iwe ukanyatso tarisa iyo chromaticity dhizaini, iwe uchaona kuti imwechete tembiricha yemavara inogona kuenderana neakawanda emavara macoordinates, nepo peya yemavara inoronga inongoenderana nekudziya kweruvara rumwe chete. Nokudaro, zvakanyatsorurama kushandisa mavara ekubatanidza kutsanangura ruvara rwechiedza. Iyo indekisi yekuratidzira pachayo haina chekuita nekurongeka kweruvara uye tembiricha yeruvara, asi iyo yakakwira tembiricha yeruvara, kutonhora kweruvara rwechiedza, zvishoma zvitsvuku zviri muchiedza chechiedza, uye zvakaoma kuwana yakanyanya kuratidzwa index. Kune magetsi anodziya ane tembiricha yeruvara yakaderera, kune zvimwe zvikamu zvitsvuku, kuvharika kwehupamhi, uye padyo nenzvimbo yemwenje wechisikigo, saka iyo color rendering index inogona kunge yakakwira. Ichi ndicho chikonzero ma LED ari pamusoro pe95Ra pamusika ane tembiricha yakaderera yemavara.
