Umzobo womphefumlo wokukhanya - Ijika loSasazo lokukhanya

isibanezizinto ezibalulekileyo nezibalulekileyo kubomi babantu bemihla ngemihla ngoku. Ekubeni abantu besazi indlela yokulawula amalangatye, bayayazi indlela yokufumana ukukhanya ebumnyameni. Ukususela kwimililo eqaqambileyo, amakhandlela, izibane ze-tungsten, izibane ze-incandescent, izibane ze-fluorescent, izibane ze-tungsten-halogen, izibane ze-sodium ezinoxinzelelo oluphezulu ukuya kwizibane ze-LED, uphando lwabantu ngezibane aluzange luyeke..

Kwaye iimfuno ziyanda, zombini ngokwembonakalo kunye neeparameters zokukhanya.

Uyilo oluhle ludala inkangeleko entle, ngelixa ukukhanya okuhle kunika umphefumlo

Kweli nqaku, sijonga ngokusondeleyo nangokunzulu ii-curves zokusasazwa kokukhanya. Ndingathanda ukubiza oku ngokuthi yi-sketch yomphefumlo wokukhanya.

Yintoni ii-curves zokusasazwa kokukhanya?

Indlela yokuchaza ngokwesayensi nangokuchanekileyo ukusasazwa kokukhanya. Ichaza ngokucacileyo imo, ubukhali, indlela kunye nolunye ulwazi lokukhanya ngemizobo kunye nomzobo.

 Ezintlanu eziqhelekileyoiindlela zokubonakalisa ukusasazwa kokukhanya

1.Itshathi yekhowuni

Ngokwesiqhelo yayisetyenziselwa izibane zokukhanya eluphahleni.

Njengoko kubonisiwe kumgca wokuqala womfanekiso, kuthetha ukuba ububanzi bendawo d=25 cm kumgama we-h=1 meter, umkhamo wokukhanya ophakathi Em=16160lx, kunye nomkhamo wokukhanya ophezulu Emax=24000lx.

Icala lasekhohlo yidatha. Okwangoku icala lasekunene yidayagramu eqondakalayo enamabala okukhanya avuselelekileyo. Yonke idatha ibonakala kuyo, kufuneka siqonde intsingiselo yoonobumba ukuze sifumane ulwazi.

2.ijika lokukhanya okulinganayo

(Izibane zesitalato ze-E-Lite Phantom Series LED)

Ukukhanya kwesibane sasesitalatweni kudla ngokusasazwa ngokubanzi, ngoko ke kudla ngokuchazwa ngegophe elilinganayo lokukhanya. Kwangaxeshanye, kulula ukusebenzisa iigophe zemibala eyahlukeneyo ukumela ukukhanya okwahlukileyo.

3.igophe elilinganayo

Isetyenziselwa ngokubanzi ukukhanya kwesitalato, ukukhanya kwegadi

I-0.0 ibonisa indawo esikuyo isibane, kwaye i-1 ibonisa indawo esikuyo isibane.^stIsangqa sibonisa ukuba ukukhanya yi-50 lx. Umzekelo, sinokufumana iimitha (0.6,0.6) ukusuka kwisibane, ukukhanya yi-50 lx kwindawo yeflegi ebomvu.

Lo mzobo ungentla ulula kakhulu, kwaye umyili akadingi kubala kwaye angayifumana ngqo idatha kuwo aze ayisebenzisele uyilo lokukhanyisa kunye noyilo.

4.Ijika lokusasazwa kokukhanya okulinganiselweyo kwePolar/Ijika lePolar

Ukuze uyiqonde ngokwenene, makhe sijonge ingcamango yezibalo - ii-polar coordinates kuqala.

Inkqubo yokulungelelanisa i-polar equlathe ii-engile kunye nezangqa ezimele umgama ukusuka kwindawo yokuqala.

Ekubeni uninzi lwezibane lujoliswe ezantsi, i-polar coordinate light distribution curve ithatha i-bottom njengendawo yokuqala ye-0°

Ngoku, makhe sijonge umzekelo weembovane ezitsala ibhendi yerabha ~

1^stIimbovane ezinamandla ahlukeneyo zarhuqa imitya yazo yerabha ukuze zinyuke ziye kwiindlela ezahlukeneyo. Ezo zinamandla angakumbi zinyuka zisiya kude, ngelixa ezo zinamandla angaphantsi zinokunyuka zisondele kuphela.

2^nd,zoba imigca ukuze udibanise iindawo apho iimbovane ziyeke khona

Okokugqibela, siza kuba negophe lokusasazwa kwamandla kweembovane.

Ukusuka kumzobo, singafumanisa ukuba amandla eembovane kwicala le-0° yi-3, kwaye amandla eembovane kwicala le-30° ayi-2.

Ngokufanayo, ukukhanya kunamandla—ukukhanya okunamandla

Qhagamshela amanqaku enkcazo yobukhulu bokukhanya kwiindlela ezahlukeneyo ukuze ufumane ijika lokukhanya "lokusasazwa kobunzima".

Ukukhanya kwahlukile kwiimbovane. Ukukhanya akusoze kuyeke, kodwa ubukhali bokukhanya bunokulinganiswa.

Ubunzulu bokukhanya bumelwa ngumgama ukusuka kwimvelaphi yegophe, ngeli xesha icala lokukhanya limelwa zii-angles kwii-polar coordinates.

Ngoku makhe sijonge i-curve yokusasazwa kokukhanya kwezibane zesitalato efana ne-polar coordinate light distribution curve njengoko ingezantsi:

Ngeli xesha sabelana ngeendlela ezi-5 eziqhelekileyo zokubonakalisa ukukhanya.

Kwixesha elizayo, masiyihlolisise kakuhle kunye. Luluphi ulwazi esinokulufumana kubo?
