Nkag siab txog Cov Ntawv Ntsuas Qiv Xim nrog LEDs

Sij hawm: 2020-04-16

Thaum nws hais txog qhov zoo ntawm cov teeb ci sib txawv, cov cim qhia ua xim (CRI) yog qhov ntsuas ntawm kev ntsuas, thiab nws yuav tsum them sai sai rau CRI thaum xaiv thiab siv lub teeb ci.


Tom qab ntawd peb yuav qhia luv luv kom pab koj nkag siab zoo txog lub tswv yim ntawm kev ua xim.


xim


Cov xim yog dab tsi? Qhov tseeb, tsis muaj tus kwv nws tus kheej muaj xim.

Txawm tias cov cuab yeej muaj xim ntau dhau los yuav ploj xim yog tias nyob hauv qhov chaw tsaus ntau.


Yog li ntawd, yog tias ib qho khoom yog nyob rau ntawm lub teeb rau xim, xim yuav tsum yog cov khoom ntiag tug ntawm lub teeb. Kev sib xyaw ntawm lub teeb ntawm cov yoj sib txawv feem ntau ua rau sib txawv ntawm cov xim.


Piv txwv li, thaum lub teeb ci hluav taws xob nkag mus rau hauv lub qhov muag-lub hlwb qhov kev sib tw los ntawm cov ntev ntev dua (saum 620 nm), xim liab tshwm.


* When most of the optical radiation is at an middle wavelength (around 530 nm), it will appear green.

* When the optical radiation is controlled by a shorter wavelength (about 450 nm), a blue color will appear.

* Mixtures of long and medium wavelengths may appear yellow, and mixtures of short and long wavelengths may appear magenta.


Rov qab mus soj ntsuam qhov kev paub dhau los ntawm kev saib cov khoom siv los cuam tshuam thiab tawg qhov xwm txheej teeb pom kev zoo, qhov no pab kom paub qhov txawv ntawm qhov kev paub xim uas tshwm sim thaum ib tus neeg saib ncaj qha rau ntawm lub teeb.



Xim Qhia Txog Qhov Ntsuas


Kev Ntsuas Cov Duab Uas Txaus Ntsuas, kuj tseem hu ua CRI, yog qhov ntsuas ntawm lub peev xwm ntawm kev rov ua xim. Nws nyob ntawm ib nplai los ntawm 1-100. Qhov qis dua CRI kev ntsuas, qhov tsawg dua cov xim yuav rov qab ua dua.


Rau cov phiaj xwm teeb pom kev zoo sab nraum zoov, sab nraum zoov CRI ntau yog RA70 txog RA80, thaum CRI sab hauv tsev yog RA85 rau RA90.Tab sis rau qhov chaw tshwj xeeb, xws li chav ua yeeb yam, chav ua haujlwm luam ntawv, lossis lwm qhov chaw uas xav tau kev hloov xim siab, CRI Performance index tuaj yeem ncav cuag RA95 rau RA98 lossis siab dua.


Qee lub teeb cov wil qhia kev dag. Qhov xim ntawm cov khoom hauv qhov tawm ntawm sab nraud yog txawv ntawm sab hauv tsev. Tias vim tias lub teeb muaj qhov sib txawv hauv cov xim muaj peev xwm.



Piv


In LED Lamps, CRI is associated with the phosphor with which the LEDs are made. To obtain a higher level of CRI, you need higher quality and higher prices, so few manufacturers use values above 90 to maintain Lower price and competitiveness.


If koj ua tibzoo saib ntawm pheej yig LED, koj yuav pom qhov txawv loj. Muaj ntau qhov chaw hauv cov xim spectrum uas tsis xa cov teeb pom kev zoo. Qhov no yog qhov ntxim nyiam heev uas yuav ua rau muaj suab nrov txawv txawv hauv lub suab tawv nqaij lossis lwm yam xim pov rau hauv cov duab, uas yog qhov xav tsis txog, tsis xav ua thiab tsis tuaj yeem.


Qhov siab tshaj plaws CRI uas tuaj yeem ua tiav hauv cov kab hluav taws xob hauv LED yog CRI 98, uas yog siv rau hauv tsev cia puav pheej, kos duab kos duab, khw muag khoom khaub ncaws, khoom siv tshuaj pleev ib ce khoom lag luam, thiab lwm yam kev siv uas xav tau cov xim zoo.



Qhov chaw teeb pom kev LED


Leej twg muaj qhov zoo tshaj teeb pom kev zoo xim? hnub ci, uas txhais tias yog CRI100.


Hnub ci ntuj muaj tag nrho cov xim hauv lub teeb pom kev pom, ntxiv rau lub zog lossis qib zog ntawm txhua qhov xim ntawm lub teeb yuav luag txhua yam hauv lub spectrum.


Feem ntau, txhua lub teeb ci nrog CRI kev ntsuas ntawm 90 lossis siab dua yuav ua siab zoo tso saib xim. Feem ntau qhov ua tau zoo tungsten yuav muaj CRI kev ntsuas 90 lossis siab dua (feem ntau dhau 95). Hnub ci yuav ua tau zoo tshaj plaws ntawm txhua qib CRI.


Ntxiv nrog rau nruab hnub nrig, yuav ua li cas kom ua tau lub teeb pom kev zoo tshaj plaws xim zoo? Lo lus teb yog kom muaj lub teeb ci nrog lub teeb pom kev ua tiav thiab cov teeb pom kev zoo tas mus li.


Yuav kom ua tiav lub hom phiaj, peb tau ua cov teeb ci LED ntawm lwm lub teeb pom kev zoo li cas pom pom lossis tsis pom.
