Dhammaan fiilooyinka iftiinka ma leeyihiin UGR?

Halbeeg la yiraahdo UGR, ama Midaysan Glare Rating, ayaa loo isticmaalaa in lagu qiimeeyo sida aan raaxo lahayn ee dhalaalka ka imanaya isha iftiinka. Maadaama UGR ay inta badan ku xiran tahay qalabyo nalaleed oo rasmi ah oo loo isticmaalo goobaha ganacsiga iyo goobaha xirfada ah halkaasoo kontoroolka dhaldhalaalka uu muhiim u yahay, dhammaan xariijimaha iftiinka ma laha darajadan.

Xariijimaha khafiifka ah ma mari karaan shahaado ama habraacyada tijaabada ee aaladaha iftiinka caadiga ah ee caadiga ah, gaar ahaan haddii loogu talagalay iftiiminta jawiga ama qurxinta. Si kastaba ha noqotee, soosaarayaashu waxay bixin karaan qiimeynta UGR ama faahfaahin ku saabsan maaraynta iftiimaya haddii xariijinta iftiinka loogu talagalay in lagu isticmaalo deegaannada ay dhici karto in dhaldhalaalka ay tahay arrin.

Waxaa lagugula talinayaa inaad dib u eegto faahfaahinta alaabta ama aad la hadasho soo saaraha haddii aad raadinayso fiilooyin iftiin leh oo qiimee UGR gaar ah leh.

Maaddaama UGR ay tahay tiro lagu go'aamiyay cabbirro gaar ah, tijaabinta Qiimaynta Midaysan ee Glare (UGR) ee laydhka laydhka LED sida caadiga ah waxay ku lug leedahay raacitaanka nidaam go'an. Dulmar guud oo ku saabsan hababka loo baahan yahay si loo tijaabiyo UGR ayaa lagu bixiyaa hoos:

Habee Deegaanka:
Ku samee tijaabada meel la kontoroolo, sida qol leh nashqad horay loo sii go'aamiyay iyo daawaynta dusha sare. Ilaha kale ee iftiinka ee qalloocin kara xogta waa inaysan joogin qolka.
Qalabka lagu qiyaaso:
Si loo go'aamiyo sida iftiinka iftiinka iyo meelaha ku hareeraysan u iftiiman yihiin, isticmaal mitirka iftiinka. Hubi in mitirku uu saxan yahay oo ku habboon yahay cabbirka iftiinka aad u baahan tahay si aad u cabbirto.
Samee Qodobbada Qiyaasta:
Go'aami meelaha cabbirada. Booska kormeeraha (guud ahaan heerka isha) iyo meelaha ilaha iftiinka (nalalka laydhka LED) ayaa inta badan ku jira tan.
Xisaabi Iftiinka:
Marka laga eego aragtida goob-joogaha, cabbir iftiinka xariijimaha LED-ka dhalaalka xaglo kala duwan. Tani waxay ku lug leedahay cabbiraadda dhalaalka xaglaha ka tarjumaysa dhaldhalaalka suurtagalka ah iyo sidoo kale toos uga imanaya isha iftiinka.

Xisaabi UGR:
Isticmaal qaacidada UGR, taas oo tixgalinaysa qiyamka iftiinka ee la cabbiray, xaglaha ilaha iftiinka marka loo eego goobjoogaha, iyo iftiinka gadaasha. Habkani waa sida soo socota:
[
UGR = 8 \cdot \log_{10} \bidix( \frac{0.25 \cdot \sum_{i=1}^{n} L_i \cdot \Omega_i}{L_b} \right)
]

Halkee:

(L_i) = iftiinka isha iftiinka (candelas halkii mitir labajibbaaran)
( \ Omega_i ) = xagal adag ee isha iftiinka (ee steradians)
(L_b) = iftiinka asalka ah (ee candelas halkii mitir laba jibaaran)

Falanqee natiijooyinka:
Xaaladaha intooda badan, qiimaha UGR ee ka yar 16 ayaa loo arkaa mid la aqbali karo, si kastaba ha ahaatee qiimayaasha ka badan 19 waxay soo jeedin karaan dhalaal daran.
Diiwaanada:
Tixraaca mustaqbalka ama u hoggaansanaanta baahiyaha, diiwaangeli dhammaan cabbirada, xisaabinta, iyo xaaladaha tijaabada.
La hadalka khabiirka iftiinka ama shirkad diiradda saarta naqshadaynta iftiinka iyo cabbirka waxay ku caawin kartaa haddii aadan aqoon u lahayn habka tijaabada ama aadan haysan qalabka loo baahan yahay.

Waxaan haynaa xariijin cusub oo ka hortagi karta dhaldhalaalka, fadlannala soo xidhiidhhaddii aad rabto inaad wax badan ka ogaatoxariijimaha neon-ka-hortagga.
