Izibane zeLed Basic Parameter Definition

1.I-Luminous Flux (F) 

Isimbuku samandla akhutshwa ngumthombo wokukhanya kwaye afunyenwe ngamehlo omntu yi-flux ekhanyayo (iyunithi: lm(lumen)). Ngokubanzi, amandla aphezulu ohlobo olufanayo lwesibane, lukhulu ngakumbi ukukhanya okukhanyayo. Umzekelo, ukukhanya okukhanyayo kwesibane se-incandescent esiqhelekileyo se-40 yi-350-470Lm, ngelixa ukukhanya okukhanyayo kwe-40W eqhelekileyo yesibane esiqhelekileyo se-tube fluorescent malunga ne-28001m, engama-6 ~ 8 amaxesha wesibane se-incandescent.

 

2.Ubukhulu obukhanyayo(I)

Umbane okhanyayo okhutshwa ngumthombo wokukhanya kwiyunithi eqinileyo ye-engile kwicala elinikiweyo ubizwa ngokuba bubunzulu obukhanyayo bomthombo wokukhanya kwelo cala, kwaye ngokungathanga ngqo kuthiwa bubunzulu obukhanyayo (iyunithi yi-cd (candela)), 1cd=1m/1s. .

3.Illuminance(E)

Ukukhanya okukhanyayo okufunyenwe kwiyunithi nganye yendawo ekhanyisiweyo kubizwa ngokuba yi-illuminance (iyunithi yi-1x(lux), oko kukuthi, 11x=1lm/m². Ukukhanya komhlaba emini enkulu nokukhanya okunamandla ehlotyeni kumalunga ne-5000lx, ukukhanya komhlaba ngemini enelanga. ebusika malunga ne-20001x, kunye nokukhanya komhlaba ngobusuku benyanga obucacileyo malunga ne-0.2lX.

4.Ukukhanya (L)

Ukukhanya komthombo wokukhanya kwicala elithile, iyunithi yi-nt (ii-nits), yi-flux ekhanyayo ekhutshwa yiyunithi yendawo eqikelelweyo kunye neyunithi ye-engile eqinileyo yomthombo wokukhanya kwelo cala. Ukuba yonke into ithathwa njengomthombo wokukhanya, ke ukukhanya kuchaza ukuqaqamba komthombo wokukhanya, kwaye ukukhanya kuphatha nje yonke into njengento ekhanyisiweyo. Sebenzisa ibhodi yeplanga ukubonisa. Xa umtha othile wokukhanya ubetha ibhodi yeplanga, kubizwa ngokuba kungakanani na ukukhanya kwebhodi, kwaye kungakanani ukukhanya okubonakaliswa yibhodi kwiliso lomntu, kubizwa ngokuba kungakanani ukukhanya kwebhodi, oko kukuthi, ukukhanya. ilingana nokukhanya kwandiswe ngokubonakalayo, kwindawo enye kwigumbi elinye, iqhekeza lelaphu elimhlophe kunye neqhekeza Ukukhanya kwemarike emnyama kuyafana, kodwa ukukhanya ezahlukeneyo.

5.UkuSebenza okuLuminous koMthombo wokuKhanya

Umlinganiselo wokukhanya okukhanyayo okuphuma kumthombo wokukhanya kumandla ombane (w) asetyenziswe ngumthombo wokukhanya kubizwa ngokuba bubuchule obuLuminous bomthombo wokukhanya, kwaye iyunithi yilumens/watt (Lm/W)

6.Ubushushu boMbala(CCT)

Xa umbala wokukhanya okhutshwa ngumthombo wokukhanya ukufutshane nombala osasazwa ngumzimba omnyama kubushushu obuthile, ubushushu bomzimba omnyama bubizwa ngokuba bubushushu bombala (CCT) bomthombo wokukhanya, kwaye iyunithi yi-K. . Imithombo yokukhanya enobushushu bombala obungaphantsi kwe-3300K inombala obomvu kwaye inika abantu imvakalelo efudumeleyo. Xa ubushushu bombala budlula i-5300K, umbala uba bluish kwaye unika abantu imvakalelo epholileyo. Ngokuqhelekileyo, imithombo yokukhanya enobushushu bombala obungaphezulu kwe-4000K isetyenziswa kwiindawo ezinobushushu obuphezulu. Kwiindawo ezisezantsi, sebenzisa imithombo yokukhanya engaphantsi kwe-4000K.

7.Isalathiso sokuBonelela ngoMbala(Ra)

Zombini ukukhanya kwelanga kunye nezibane ze-incandescent zikhupha i-spectrum eqhubekayo. Izinto zibonisa imibala yazo yokwenyani phantsi kokukhanya kwelanga okukhulu kunye nezibane ze-incandescent, kodwa xa izinto zikhanyiswa zizibane zokukhupha igesi ye-spectrum engapheliyo, umbala uya kuba needigri ezahlukeneyo zokuGqwetha, iqondo lomthombo wokukhanya ukuya kumbala wenyani wento. iba lunikezelo lombala lomthombo wokukhanya. Ukulinganisa unikezelo lombala lomthombo wokukhanya, ingqikelelo yesalathiso sombala iyaziswa. Ngokusekelwe kukukhanya okusemgangathweni, isalathisi sombala sichazwa njenge-100. Isalathiso sombala weminye imithombo yokukhanya singaphantsi kwe-100. Isalathisi sombala sichazwa nguRa. Ixabiso elikhulu, kokukhona unikezelo lombala lomthombo wokukhanya.

8.I-Avareji yoBomi

Umndilili wobomi ubhekisa kwinani leeyure ezithi i-50% yezibane ezikwibhetshi yezibane zikhanyise xa zonakele.

9.Ubomi bezoqoqosho

Ubomi bezoqoqosho bubhekiselele kwinani leeyure xa ukukhutshwa kwe-beam edibeneyo kuncitshiswa kumlinganiselo othile, kuthathelwa ingqalelo umonakalo webhalbhu kunye nokuthotywa kwe-beam output. Umlinganiselo yi-70% yemithombo yokukhanya yangaphandle kunye ne-80% yemithombo yokukhanya yangaphakathi.

10.Ubuchule obuqaqambileyo

Ukusebenza okukhanyayo komthombo wokukhanya kubhekiselele kumlinganiselo wokukhanya okukhanyayo okukhutshwa ngumthombo wokukhanya kumandla ombane we-P asetyenziswe ngumthombo wokukhanya.

11.Dazzle ukukhanya

Xa kukho izinto ezigqame ngokugqithisileyo kwibala lokujonga, iya kuba ingakhululeki ngokubonakalayo, ebizwa ngokuba yi-dazzle light. ukukhanya kwedazzle yinto ebalulekileyo echaphazela umgangatho wemithombo yokukhanya.
