Yintoni i-suitbale lumen yokusetyenziswa ngaphakathi?

I-lumen yiyunithi yokulinganisa ubungakanani bokukhanya okukhutshwa ngumthombo wokukhanya. Ukukhanya kwesibane sestrip kudla ngokulinganiswa kwii-lumens ngenyawo okanye ngemitha, kuxhomekeke kwiyunithi yokulinganisa esetyenzisiweyo. Okukhona kukhanya ngakumbiisibane sokususa imicu, ixabiso le-lumen liphezulu.

Landela la manyathelo ukuze ubale imveliso ye-lumen yomthombo wokukhanya:

1. Chonga i-luminous flux: Isixa sisonke sokukhanya esikhutshwa ngumthombo wokukhanya, esilinganiswa kwii-lumens, sibizwa ngokuba yi-luminous flux. Olu lwazi lunokufumaneka kwiphepha ledatha okanye kwiphakheji yomthombo wokukhanya.

2. Bhala ubungakanani bendawo: Ukuba ufuna ukwazi i-lumen output nge-square foot okanye imitha, kufuneka ubhale indawo ekhanyisiweyo. Ukuze wenze njalo, yahlula i-luminous flux ngendawo yonke ekhanyisiweyo. Ukuba umthombo wokukhanya we-lumen oyi-1000 ukhanyisa igumbi le-100 square foot, i-lumen output nge-square foot yi-10 (1000/100 = 10).

3. lungisa i-engile yokujonga: Ukuba ufuna ukwazi i-lumen output ye-engile ethile yokujonga, kufuneka ulungise i-engile ye-beam yomthombo wokukhanya. Oku kudla ngokubonakaliswa ngamadigri kwaye kunokufumaneka kwiphepha ledatha okanye kwiphakheji. Ungasebenzisa ifomula ukubala i-lumen output ye-engile ethile yokujonga, okanye ungasebenzisa umthetho wesikwere esichaseneyo ukuze ufumane uqikelelo.

Khumbula ukuba ukusebenza kakuhle komthombo wokukhanya kunokwahluka ngokusekelwe kwezinye iiparameter, ezifana nokubonakaliswa kwemiphezulu kwindawo ekhanyisiweyo. Ngenxa yoko, ukuphuma kwe-lumen yinto enye ekufuneka iqwalaselwe xa ukhetha umthombo wokukhanya.

Ukukhanya okufanelekileyo kweumgca wokukhanyisa wangaphakathiiyahluka ngokuxhomekeke kuhlobo kunye nenjongo yokukhanya. Nangona kunjalo, uluhlu olufanelekileyo lokukhanyisa imicu ye-LED luya kuba phakathi kwe-150 kunye ne-300 lumens ngenyawo (okanye i-500 kunye ne-1000 lumens ngemitha). Olu luhlu lukhanya ngokwaneleyo ukunika ukukhanya okufanelekileyo kwimisebenzi efana nokupheka, ukufunda, okanye umsebenzi wekhompyutha, ngelixa lukwasebenzisa amandla kwaye lunegalelo ekudalweni kwendawo ekhululekileyo nethomalalisayo. Khumbula ukuba ubushushu bombala kunye nokuma komcu, kunye nomgama phakathi komcu kunye nomphezulu okhanyiswayo, konke oku kunokuba nefuthe kwimveliso ethile ye-lumen.
