Ngokohlalutyo lweenkcukacha-manani, okwangoku, ixabiso lepetroli kwiinqanawa zokuloba e-China libalelwa malunga ne-50% ~ 60% yeendleko zokuloba, ngaphandle kwemivuzo yabasebenzi, ukugcinwa kweenqanawa zokuloba, ukongeza umkhenkce, ukongeza amanzi, ukutya kunye neendleko ezahlukeneyo, njl. , uninzi lweenqanawa zokuloba azinathemba ngengeniso yazo; Ukukhanya kokuloba kwe-LED kusekelwe kwinjongo yokunciphisa ukusetyenziswa kwamandla okuloba, kunzima ukuvuselela umnqweno wokuthenga, ukonga ukusetyenziswa kwepetroli akunamdla malunga nomnini wenqanawa, imveliso ekhulayo ibandakanyeka ekulobeni imfuno ebalulekileyo yokuloba, kunye nokonga amandla. ikakhulu ibonisa ukuziqhelanisa nomgaqo-nkqubo karhulumente.
Ukuvavanywa kwesibane sentlanzi ye-LED kugxininise ekugcinweni kwamafutha, ukungahoywa kweenzuzo zokunyusa isivuno eziziswa ngobuninzi bokukhanya kunye nomgangatho wokukhanya, eyona nto iphambili ukuba ukutshintshwa kwesibane sentlanzi ye-LED kunzima ukuba samkelwe yimarike; Ukuthengiswa kokukhanya kokuloba kwe-LED kukuba abalobi banokunyusa imveliso kwaye bafumane impumelelo ephezulu yokuloba kunye neenzuzo emva kokutshintshwa, le nzuzo iya kuphelisa ngempumelelo iindleko zokuthengaI-LED yokuloba ngaphantsi kwamanzi ukukhanya, kunye noyilo lwemveliso olunganikeli ingqalelo kwisiphumo sokwandisa imveliso kunzima ukufumana amandla okuthenga abalobi.
Ngokutsho kwedatha ekhoyo ekhaya nakwamanye amazwe, phantsi kwesiseko sokuqinisekisa ukunyuka kwemveliso, ukonga amandla okusetyenziswa kwamandla okuloba malunga ne-45% luphawu olufanelekileyo (idatha ibalwa ngumthombo wokukhanya oqaqambileyo oqinileyo weZiko loPhando).
Sikholelwa ukuba ingcamango yoyilo lweemveliso zezibane zeentlanzi ze-LED kufuneka ziqale ziqwalasele ukuba zingaphucula imveliso yokubambisa ekhoyo, iphucule intsebenzo yokuloba kumjikelezo wokuloba, ayinako nje ngenjongo yokonga amandla, ukuba awukwazi ukusungula imveliso kunye nemveliso. ukonga amandla, izinga lokuphelisa amashishini kwiminyaka embalwa ezayo liya kuba phezulu kakhulu.
I-5, udidi lweteknoloji yokukhanya kweentlanzi ze-LED
Injongo yobuchwephesha yokuqokelela izibane zeentlanzi kukufezekisa i-phototaxis ekhangayo yokungeniswa kokukhanya kweentlanzi ukunyusa ukubamba, okubizwa ngokuba yi-phototaxis, kubhekiselele kwiimpawu zezilwanyana ekuvuseleleni ukukhanya kwemitha yentshukumo ekhokelayo. Intshukumo ekhokelela kumthombo wokukhanya ibizwa ngokuba yi "positive phototaxis", kwaye intshukumo ekhokelela kude nomthombo wokukhanya ibizwa ngokuba "negative phototaxis".
Kukho ubuncinci bexabiso lokuphendula (ixabiso lomqobo) lokuziphatha kwentlanzi ekuphenduleni ukukhanya kwemitha yeentlanzi zaseLwandle ezinomsebenzi wokubonwayo, kwaye umlinganiselo osisiseko wexabiso lomqobo umiselwa ngethuba lokuqubha ixesha lentlanzi ukusuka kwindawo emnyama ukuya kwindawo eqaqambileyo. Nangona kunjalo, uphando lwangoku lwezemfundo lusebenzisa i-avareji yombono weliso lomntu oqaqambileyo, oya kuvelisa ingxaki yokukhanya okubangelwa kuphando ngoomatshini.
Ukongezelela, ngenxa yemilinganiselo eyahlukeneyo yomzimba yokuphendula iintlobo ezahlukeneyo zeentlanzi, ukuthatha ixabiso lokukhanya njengomzekelo, uphando lwangoku lukholelwa ukuba ixabiso elibalulekileyo leeseli ze-cone zentlanzi yi-1-0.01Lx, kunye neeseli zekholomu: 0.0001 -0.00001Lx, ezinye iintlanzi ziya kuba ngaphantsi, iyunithi yokukhanyisa kukubonakalisa ukukhanya okukhanyayo okuqhelekileyo kwimitha yesikwere ngomzuzwana, ukusetyenziswa kwale yunithi ukuvakalisa ubungakanani bokukhanya kwi-lens ye-fish-iso kunzima ngokwenene, kufuneka. Qaphela ukuba umlinganiselo wexabiso lokukhanya kwimpazamo yomlinganiselo wokukhanya okuphantsi bukhulu kakhulu.
Masithi imbonakalo yembonakalo yesibane somqokeleli iboniswe kumzobo:
Ngokwexabiso lomgubasi weeseli zekholamu ye-fish-eye yi-0.00001Lx, inani elihambelanayo le-quantum yokukhanya lingabalwa nge-XD factor yefom ye-spectral, oko kukuthi, amandla emitha ye-1 yezigidigidi zeefotoni kwindawo ye-1 square micron. Ukusuka kweli xabiso lokuguqulwa, kunokubonwa ukuba ngokwenene kukho amandla aneleyo e-photon ukuvuselela iiseli zekholomu ye-fish-eye ukuvelisa ukuvuselela. Enyanisweni, umda wale mpendulo unokuba ngaphantsi, kwaye ngokusebenzisa i-quantum metric yokukhanya, sinokuseka ulungelelwaniso oluchanekileyo kunye nohlalutyo lwe-cytological.
Iyunithi yokukhanya ye-quantum ye-spectrum ingasetyenziselwa ukuhlalutya ngokuchanekileyo ixabiso lobungakanani bemitha yokukhanya, kwaye kwangaxeshanye utshintshe ingqiqo yangoku yomthamo kunye nomgama wemitha yokukhanya kumanzi olwandle ngokusekelwe kwixabiso lokukhanya, kwaye umisele impendulo ebonakalayo yemitha yokukhanya kunye neliso lentlanzi kwithiyori yophando olufanelekileyo lokudluliselwa kwamandla.
Impendulo yentlanzi kwimitha yokukhanya idinga ukwahlula phakathi kwempendulo yembonakalo kunye nempendulo yentshukumo, kwaye impendulo yentshukumo ifanele ummandla apho ibala lemitha yokukhanya lilingana ngokulinganayo. Ekubeni ukubonakaliswa kwe-quantum yokukhanya ayifuni ulwalathiso oluthile, kulula ukwenza imodeli kunye nokubala ukungena kwamehlo entlanzi echazwe yintsimi yokukhanya kwe-quantum emanzini olwandle.
Ukuguquguquka kweentlanzi kwibala lemitha yokukhanya, ngenxa yokuba ukukhanya kwemitha kumanzi olwandle kukhutshwe kwi-gradient, intlanzi ye-phototactic iya kuhamba kuluhlu lwe-adaptive yemitha yokukhanya, i-gradient nganye ichazwa yi-uniform light quantum field iya kuba nentsingiselo ngakumbi, emva kwayo yonke into, ixabiso lokukhanyisa lisiyalele.
Uphononongo lubonise ukuba uninzi lweentlanzi lunobuntununtunu bokusabela kumaza ahlukeneyo, kwaye umahluko kwimpendulo yembonakalo phakathi kweentlanzi eziselula kunye neentlanzi zabantu abadala awukho phezulu, kodwa uninzi lweentlanzi zineengxaki zokuqaphela ubude bobude (ezifana nobumfama bombala bomntu). Ukususela kumbono wendlela yokuphendula ye-spectral yeeseli ezibonakalayo, i-superimposed spectral form yeentlobo ezimbini ze-monochromatic light radiation iphezulu kunempembelelo ye-spectral ye-wavelength enye.
Impendulo yeentlanzi zaseLwandle kubude bemitha yokukhanya imalunga ne-460-560nm, ephezulu kwiintlanzi zamanzi acwengileyo, kwaye impendulo yamehlo eentlanzi kuluhlu lwe-wavelength inxulumene nokusingqongileyo. Ukusuka kwimbono yoluhlu lwemitha ye-spectral, ibhendi ye-spectral yolu luhlu inowona mgama omde wemitha kumanzi olwandle, kwaye ikwaluluhlu lobude bempendulo yamehlo entlanzi. Umatshini unengqiqo ngakumbi ukuchaza ukusuka kwitekhnoloji ye-spectral.
Kwimeko yokukhanya kwemvelaphi yemitha yokukhanya, ifototaxis yentlanzi iyancitshiswa, ngoko ke kuyimfuneko ukunyusa isixa sokukhanya komthombo wokukhanya okanye uhlengahlengiso loluhlu lwamaza ukuze kuphuculwe i-inductance. Lo mcimbi uhambelana nendlela yokubona ukuba i-superposition two wavelengths yokukhanya iphezulu kune-wavelength enye, kwaye ingasetyenziselwa ukuchaza into efunekayo ukuqinisa ukukhanya okuqokelelwa yintlanzi phantsi kokukhanya kwenyanga. Ezi zifundo ziseludidi lwetekhnoloji ye-spectral ye-wavelength kunye nefom ye-spectral.
Ubuchwephesha be-fish-lamp spectroscopy kufuneka budibanise i-geometric optics kunye nendlela yokusasazwa kweefotoni ezisasazwa ngemidiya eyahlukeneyo. Ukususela kuhlalutyo lovavanyo, kunokubonwa ukuba ibinzana lokugqibela liyifom ye-spectral kunye ne-wavelength, engenanto yakwenza neeparameters zokukhanyisa.
Ukongeza, kwibhendi ye-UVR, ukubonakaliswa kolu luhlu lwe-wavelength alunakuchazwa ngenxa yeeparamitha zokukhanyisa, njengemeko yokukhanya kwe-zero, kodwa ingcaciso ehambelanayo inokufumaneka kubuchule be-spectral.
Kubaluleke kakhulu ukufunda i-phototaxis yeentlanzi kunye neyunithi efanelekileyo yokulinganisa umzimba wemitha yokukhanya yesibane sokuloba.
Undoqo wobuchwephesha betekhnoloji kuphononongo lwesiphumo sembonakalo yembonakalo yeso lentlanzi kunye nokuphendula okubonakalayo kubude bomsinga, ezi zifundo zinxulumene nempendulo enemiqathango kunye nempendulo engenamiqathango, ngaphandle kophando olusisiseko, amashishini akakwazi ukuvelisa okulungileyo. ukusebenza kwesibane sentlanzi ye-LED.
6, kufuneka bajonge ukukhanya kwemitha kwiliso lentlanzi
Ilensi yeliso lomntu yi-convex lens, kwaye ilens yeliso lentlanzi yilens engqukuva. I-lens ye-spherical inokunyusa inani leefotoni ezifakwe kwiso lentlanzi, kwaye intsimi yokujonga iliso lentlanzi imalunga ne-15 degrees enkulu kuneso lomntu. Ngenxa yokuba i<em>lens engqukuva ingenako ukuhlengahlengiswa, intlanzi ayikwazi ukubona izinto ezikude, ezingqinelana nendlela eshukuma ngayo i<em>phototropism.
Kukho umahluko phakathi kwebala elingasentla kunye nokukhanya okungaphantsi kwamanzi, okubangela ukuziphatha kweempendulo zeentlobo zeentlanzi ezahlukeneyo, okusisiphumo sokuphendula kweso lentlanzi kwi-spectrum.
Ixesha lokudibanisa kunye nexesha lokuhlala leentlanzi ezahlukeneyo kummandla wokukhanya kwemitha yahlukile, kwaye imowudi yentshukumo kwindawo yokukhanya kwemitha yokukhanya nayo yahlukile, okuyimpendulo yokuziphatha kweentlanzi kwimitha yokukhanya.
Iintlanzi zinempendulo ebonakalayo kwi-UVR, engafundwanga kakuhle.
Iintlanzi aziphenduli kuphela kwimitha yokukhanya, kodwa kunye nesandi, ivumba, imimandla yamagnetic, ubushushu, ityuwa kunye ne-turbidity, imozulu, ixesha lonyaka, indawo yolwandle, imini nobusuku, njl. . Nangona kunjalo, impendulo yeentlanzi kwi-radiation ye-spectral ayikho enye icandelo lobugcisa, ngoko ke kuyimfuneko ukuqwalasela ngokubanzi kwisifundo sobuchwepheshe be-spectral yesibane seentlanzi.
