Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza Light Unit Converter kusukela Apogee Instruments sinquma nezingqungquthela phakathi ukukhanya units ezahlukene imithombo ehlukahlukene ukukhanya kuhlanganise T5 Sylvania fluorescent lights, halide metal, high pressure sodium, nokukhanya kwelanga. Units zihlanganisa emisebeni shortwave (SW), photosynthesis ikhasi lesikhwama sasekhaya ecucuza (PPF, PPFD), Lux (LX) no Foot-amakhandlela (fc, LM / ft2, noma ft-c).

Izincazelo:

Kushisa bhé Shortwave - radiation Shortwave (SW) ungamandla babugcwele yamaza in the ebonakalayo (Vis), eduze-ultraviolet (UV), futhi eduze-infrared (Nir) Spectra. Akukho standard cut-off for the uhla eduze-infrared; Ngakho, lo shortwave uhla emisebeni futhi ezihlukahlukene kuchazwa. Kungase kube emiphumeleni sichazwa ukuba ihlanganise wonke emisebeni nge inamandla phakathi 0.1μm kanye 5.0μm noma esinda kuchazwe ukuze ihlanganise emisebeni kuphela phakathi 0.2μm and 3.0μm. Kukhona ecucuza ngemisebe little (ngokwesigaba W / m²) ezindaweni eMhlabeni ngezansi 0.2μm noma ngaphezu 3.0μm, nakuba ikhasi lesikhwama sasekhaya ecucuza uhlala abalulekile kuze kufike 6.0μm, kuqhathaniswa mfushane inamandla fluxes. UV-C emisebeni emabhulohweni kusukela 0.1μm ukuba .28μm, UV-B kusuka 0.28μm kuya 0.315μm, UV-A kusuka 0.315μm kuya 0.4μm, nomkhakha isesihlalweni 0.4μm kuya 0.7μm, futhi Nir kunjalo kusukela 0.7μm kuya 5.0 μm, ngaphesheya lapho infrared kuba ezishisayo. Emisebeni Shortwave is zihlukaniswa emisebeni longwave.

Lux - The lux (symbol: LX) kuyinto SI unit of illuminance and emittance elikhanyayo, ekukaleni ecucuza elikhanyayo per unit ndawo. Kuyinto lingana kuze fike mafutha anciphisa isikhala esingaphakathi per imitha square. In photometry, lokhu isetshenziswa njengophawu elithile umfutho, njengoba ziqondakala iso womuntu, ukukhanya hits noma sidlula a surface. Kuyinto fanekiso ukuba radiometric unit Watts per imitha square, kodwa amandla at nombono ngamunye isisindo ngokusho umsebenzi luminosity, umfuziselo zifane of human visual ukugqama ukubona.

Photosynthesis Photon Flux - photosynthesis Photon Flux (PPF), owaziwa ngokuthi photosynthesis Photon Flux Density (PPFD) noma Photosynthetically Radiation Active (par), lisho uhla Spectral (wave band) emisebeni solar kusukela nanometer 400 kuya 700 ukuthi eziphilayo photosynthesis bayakwazi ukusebenzisa inqubo ye-photosynthesis. Ukumeda par isetshenziswa kwezolimo, ezamahlathi kanye Oceanography. Enye yezimfuneko for yokulima omuhle par okwanele, kanjalo par isetshenziswa ukuhlola ezolimo kubatshali zimali. Par izinzwa ababemi emazingeni ahlukahlukene semithi ehlathini ukukala isibonelo par ukutholakala nokusetjenziswa. Par ngokuvamile zifanekiswe njengoba μmol photon / m2 / s, okuyinto kukala ecucuza photosynthesis-albhamu yezithombe (ndawo) kwabantu, noma PPFD. Par kungabuye luboniswe energy units (irradiance, W / m2); lokhu iyafaneleka energy-balance ngokucabangisisa for eziphilayo photosynthesis. Ngoba photosynthesis kuyinqubo quantum, PPFD ngokuvamile esetshenziswa plant ososayensi bezinto eziphilayo.

Foot-candle - A foot-candle (ngezinye izikhathi foot candle; esifushanisiwe fc, LM / ft2, noma ngezinye izikhathi ft-c) iyinhlangano unit non-SI of illuminance noma ngegalelo ukukhanya esetshenziswa United States kakhulu izithombe, ifilimu, ithelevishini, ukulondolozwa ukukhanyisa, greenhouse ukulima, imboni ukukhanyisa, ubunjiniyela okuhlobene ukwakhiwa-futhi ekwakheni amakhodi. Igama "footcandle" lidlulisela "ukhonkolo illuminance on a surface by umthombo owodwa-kalale foot elilodwa away". The unit kuchazwa ngokuthi lemali okukhanyisa the Ingaphakathi indilinga one-foot-engaba bengiyokwamukela uma kwakukhona iphuzu umthombo umfaniswano of one kalale enkabeni esiqondile sphere. Kungenjalo, it ingachazwa ngokuthi illuminance on a one-square foot ebusweni lapho ecucuza nombala basakaza eyodwa mafutha anciphisa isikhala esingaphakathi. Ngakho ngonyawo olulodwa-candle ilingana omunye mafutha anciphisa isikhala esingaphakathi per ngezinyawo square noma cishe 10,764 lux. In ngokoqobo, njengoba lapho kulinganiswa ekamelweni okukhanyisa, kunzima kakhulu ukukala illuminance ngokunembile kuka ± 10%, nangezinhloso eziningi kwanele ngempela ukucabanga omunye footcandle njengoba eyishumi lux njengoba ngokuvamile kwenziwa embonini zokukhanya.
