Chojambula cha mzimu wa kuwala -Light Distribution Curve

nyalendi zinthu zofunika kwambiri pa moyo watsiku ndi tsiku wa anthu tsopano.Popeza kuti anthu amadziwa kulamulira malawi, amadziwa mmene angapezere kuwala mumdima.Kuchokera pamoto, makandulo, nyali za tungsten, nyali za incandescent, nyali za fulorosenti, nyali za tungsten-halogen, nyali za sodium zothamanga kwambiri kupita ku nyali za LED, kafukufuku wa anthu pa nyali sizinayimepo..

Ndipo zofunikira zikuchulukirachulukira, potengera mawonekedwe ndi mawonekedwe a kuwala.

Kupanga kwabwino kumapanga mawonekedwe osangalatsa, pomwe kuwala kwabwino kumapereka mzimu

M'nkhaniyi, tikuyang'anitsitsa & mozama ma curve ogawa kuwala.Ndikufuna kuchitcha chithunzi cha mzimu wa kuwala.

Kodi ma curve ogawa kuwala ndi chiyani?

Njira yofotokozera mwasayansi komanso molondola kugawa kwa kuwala.Imalongosola momveka bwino mawonekedwe, kulimba, mayendedwe ndi zidziwitso zina za kuwala kudzera pazithunzi & zojambula.

 Zisanu zofanananjira zofotokozera za kugawa kuwala

1.Cone chart

Nthawi zambiri amagwiritsidwa ntchito popanga zowunikira padenga.

Monga momwe zasonyezedwera pamzere woyamba wa chithunzichi, zikutanthauza kuti m'mimba mwake d=25 cm pamtunda wa h=1 mita, kuwala kwapakati Em=16160lx, ndi kuwala kwakukulu Emax=24000lx.

Mbali yakumanzere ndi data.Panthawiyi, mbali yakumanja ndi chithunzi chowoneka bwino chokhala ndi mawanga opepuka.Deta yonse ikuwonetsa momwemo, timangofunika kumvetsetsa tanthauzo la zilembo kuti tidziwe zambiri.

2.equiangular kuwala mwamphamvu pamapindikira

Kuwala kwa kuwala kwa mumsewu nthawi zambiri kumagawidwa mofala kwambiri, choncho nthawi zambiri kumafotokozedwa ndi mphira wofanana wa kuwala kwamphamvu.Panthawi imodzimodziyo, ndizomvekanso kugwiritsa ntchito ma curve amitundu yosiyanasiyana kuyimira kuwala kosiyana.

3.equiluminous pamapindikira

Nthawi zambiri amagwiritsa ntchito kuwala kwa msewu, kuwala kwa dimba

The 0.0 imasonyeza malo a nyali, ndi 1^stkuzungulira kumasonyeza kuti kuwala ndi 50 lx.Mwachitsanzo, tithanso kutenga (0.6,0.6) mita kuchokera pa nyali, chowunikira ndi 50 lx pamalo ofiira mbendera.

Chithunzi chomwe chili pamwambapa ndi chowoneka bwino, ndipo wopanga sayenera kuwerengera ndipo atha kupeza mwachindunji deta kuchokera pamenepo ndikuigwiritsa ntchito popanga zowunikira & kapangidwe kake.

4.Polar coordinate light distribution curve/Polar Curve

Kuti timvetse bwino, Tiyeni tiwone lingaliro la masamu- polar coordinates poyamba.

Dongosolo la polar coordinate lokhala ndi makona ndi mabwalo omwe amayimira mtunda kuchokera komwe adachokera.

Popeza magetsi ambiri amawongoleredwa kumunsi, njira yolumikizira kuwala kwa polar nthawi zambiri imatenga pansi ngati poyambira 0 °.

Tsopano, tiyeni tiwone chitsanzo cha nyerere zikukoka gulu la rabala ~

1^st, nyerere zokhala ndi mphamvu zosiyanasiyana zinakoka mphira zawo kuti zikwere mbali zosiyanasiyana.Amene ali ndi mphamvu zambiri amakwera kutali, pamene omwe ali ndi mphamvu zochepa amatha kukwera pafupi.

2^nd,jambulani mizere yolumikiza malo omwe nyerere zinaima

Pomaliza, Tidzakhala ndi mphamvu kugawa pamapindikira nyerere.

Kuchokera pachithunzichi, titha kudziwa kuti mphamvu ya nyerere mu 0 ° mbali ndi 3, ndipo mphamvu ya nyerere mu 30 ° ndi pafupifupi 2.

Mofananamo, kuwala kuli ndi mphamvu—kuchuluka kwa kuwala

Lumikizani malo ofotokozera kukula kwa kuwala m'njira zosiyanasiyana kuti mupeze-"kufalikira kwamphamvu" kopindika kwa kuwala.

Kuwala kumasiyana ndi nyerere.Kuwala sikudzatha, koma mphamvu ya kuwala ikhoza kuyezedwa.

Kuwala kowala kumayimiridwa ndi mtunda kuchokera komwe kumayambira pamapindikira, pomwe kuwongolera kwa kuwala kumayimiridwa ndi ma angles mu ma polar coordinates.

Tsopano tiyeni tiwone momwe magetsi amisewu a polar coordinate agawira kuwala monga pansipa:

Nthawi ino tikugawana 5 njira zodziwika bwino zowunikira.

Nthawi ina, Tiyeni tione bwinobwino pamodzi.Kodi tingapeze uthenga wotani kwa iwo?
