Waa maxay LED?
LED waa erayga la soo gaabiyey LIGHT EMITTING DIODE, waa qayb bixisa iftiin monochromatic ah oo leh socodka korantada.
LED-yadu waxay siinayaan naqshadeeyayaasha nalalka leh qalab cusub oo cusub oo ka baxaya si ay uga caawiyaan inay gaaraan natiijooyinka ugu fiican oo ay horumariyaan xalal iftiin leh oo leh saameyn la yaab leh oo farsamo ahaan aan suurtagal ahayn in la gaaro.LED tayo sare leh oo leh CRI> 90 index oo lagu qiimeeyay 3200K - 6500K ayaa sidoo kale ka soo muuqday suuqa.kuwan dhowsanads.
Iftiinka, isku midka ah, iyo samaynta midabka nalalka LED ayaa la hagaajiyay ilaa xadka ay hadda loo isticmaalo noocyo kala duwan oo nalal ah.Qaybaha LED-ku waxay ka kooban yihiin tiro go'an oo ah daaydhyo iftiiminaya oo ku rakiban sabuurad wareeg ah oo daabacan (adag oo dabacsan) oo leh aalado nidaaminaya firfircoon ama aan toos ahayn.
Optics ama aaladaha haga iftiinka ayaa sidoo kale lagu dari karaa iyadoo ku xiran goobta codsiga si loo helo iftiin iyo iftiin kala duwan.Midabada kala duwan, cabbirka is haysta iyo dabacsanaanta cutubyadu waxay xaqiijinayaan fursado badan oo hal abuur leh codsiyo badan.
LEDs: sidee bay u shaqeeyaan?
LEDs waa qalab semiconductor ah oo koronta u beddela iftiin muuqda.Marka la tamarsiiyo (polarization toos ah), elektaroonnada waxay dhex maraan semiconductor-ka, qaarkoodna waxay ku dhacaan qayb tamar hoose ah.
Inta lagu jiro nidaamka, tamarta "badbaadisay" ayaa loo sii daayaa iftiin ahaan.
Cilmi-baaris tignoolajiyadeed ayaa oggolaatay in la gaaro 200 Im/W koronto kasta oo LED ah.Heerka horumarka ee hadda jira wuxuu muujinayaa in tignoolajiyada LED aysan wali gaarin awooddeeda buuxda.
Tilmaamaha farsamada
Waxaan inta badan ka akhrinaa badbaadada sawir-bioloji ee naqshadeynta iftiinka.Qodobkan aadka muhiimka u ah waxaa lagu go'aamiyaa cadadka shucaaca ee ka soo baxa dhammaan ilaha leh dhererka hirarka u dhexeeya 200 nm iyo 3000 nm.Soo-gaadhista shucaaca xad-dhaafka ah waxay waxyeello u geysan kartaa caafimaadka aadanaha.Heerka EN62471 wuxuu u kala saaraa ilaha iftiinka kooxo halis ah.
Kooxda Khatarta 0 (RGO): nalalka waa laga dhaafay khataraha sawir-bioloji iyadoo la raacayo heerka EN 62471.
Kooxda Khatarta 0 (RGO Ethr): luminaires waa laga dhaafay khataraha sawir-bioloji iyadoo la raacayo heerka EN 62471-IEC/TR 62778. Haddii loo baahdo, kala xiriir adeegga macaamiishayada fogaanta daawashada.
Kooxda Khatarta 1 (kooxda khatarta hoose): nalalka ma keenaan wax khatar ah sababtoo ah xaddidaadda dabeecadda caadiga ah ee qofka marka ay la kulmaan isha iftiinka.
Kooxda Khatarta 2 (Kooxda khatarta dhexe): nalalka ma keenaan wax khatar ah sababtoo ah dadka oo ka naca ilaha iftiinka aadka u ifaya ama raaxo la'aanta kulaylka awgeed.

Faa'iidooyinka isticmaalayaasha
Noocyo kala duwan oo midabyo kala duwan ah oo ay weheliyaan qaybo is haysta oo dabacsan ayaa awood u siinaya xalal naqshadeed oo badan oo hal abuur leh
Kharashka dayactirka oo la dhimay
Isticmaalka tamarta hoose, nolosha dheer ee shaqada iyo dayactirka oo la dhimay ayaa fududeynaya abuurista codsiyada xiisaha leh
Faa'iidooyinka guud
Meerkuri-free
Ma jiraan wax ka kooban IR ama UV oo laga heli karo spectrum iftiinka muuqda
Isticmaalka ilaha tamarta la cusboonaysiin karo iyo kuwa aan la cusboonaysiin karin oo yaraaday
