Ngingazi kanjani ukuthi i-PPFD ye-Light ifanelekile (kude kangakanani)?

L sethula kafushane lokho i-PPFD.

I-PPFD , noma  i-Photosnththetic Photon Flux density , ibhekisa kwinani lezinhlayiya ezikhanyayo (izithombe) ukuthi umhlaba we-Square MADE ngomzuzwana (i-PAR) Range esebenzayo ye-Photos (PAR).

Ungacabanga ukukhanya njengemvula yemvula ewa kuma-LED chip. I-PPFD isitshela ukuthi bangaki lawo awela endaweni ethile endaweni ethile okwesibili ngamunye. Njengoba ukukhanya kusakazeka njengoba kuhamba njengoba kuhamba, i-PPFD iyancipha njengoba indawo yokumboza inyuka.

1. Ukubuka okubonakalayo

Izici ezithinta i-PPFD yilezi:

• Ukusatshalaliswa kwama-chips aholwa

• I-beam angle yokukhanya

Ukuhlephula

Umehluko omkhulu phakathi  kwesitayela seBhodi (PCB)  kanye  nesitayela se-bar-style (bar)  sitholakala ngendlela ama-chip ahlelwe ngayo. Amalambu ebhodi agxilisa ama-LEDs endaweni encane, ngenkathi amalambu e-bar asakazeka. Ngakho-ke emandleni afanayo, ukufana kwabo okukhanyayo kuhlukile.

Kufana nokusebenzisa ithoshi - ngamandla ahleliwe, awukwazi ukuthola bobabili ugongolo olubanzi nokukhanya okuphezulu ngasikhathi sinye.

Beam angle

Enye into ebalulekile i-angle ye-beam. Ama-LED angahlonyiswa ama-lens ukulawula ukuthi abanzi kangakanani noma anciphise ukukhanya okusatshalaliswa - njengokugxila kwi-laser pointer.

Isibonelo esisodwa yiSanlight  GmbH  (Kwenye i-athikili, senze okufushane komkhiqizo wokuhlaziywa komkhiqizo okuphezulu okungu-20 kukhulisa imikhiqizo ekhanyayo ngo-2025. Chofoza lapha ukuze ugxume ) 

esebenzisa ama-lens ukwelula ukumbozwa kwamalambu alo wesitayela se-compact board. Umphumela uwukuhlanganiswa okuncane okufana nokukhanya okukhanyayo okufana nokukhanya kwebha - konke ngenxa yelensi.

Kodwa-ke, lo mklamo uza nezingozi:

I-Lens Material ikhwalithi ephansi → Ukulahleka okukhanyayo

Lokhu kudala umjikelezo omubi. Kungakho kubalulekile ukuthi unake  ikhwalithi yelensi  kanye  ne-dissipation yokushisa . I-Sanglight GmbH ibonakala ikwazi lokhu futhi okuvelele zombili izici zokuthengisa kwazo.

Lowo ngumqondo ojwayelekile ngemuva kwesakhiwo se-LED nama-beam angles. Kepha umklamo womkhiqizo uya ngokujulile - futhi inkinga eyodwa ebucayi ukukhanya okukhanyayo.

Ukukhanya okukhanyayo akwenzeki phakathi kwezibani ezahlukahlukene. Noma kungakapheli isitha esisodwa, i-chip ngayinye ye-LED ikhipha ukugcwala amaphethini akhanyayo. Kungakho abakhiqizi abaningi abathambekele emininingwaneni ebale amandla aholwa ngaphandle kunokuba bayeke ngokulinganayo.

2. Ukubona ngombono wokusebenzisa

Izici eziphambili ezithinta i-PPFD yilezi:  kokukhanya okukhanyayo & ukubekwa

Khulisa ukukhanya, namaconsi e-PPFD. Yehlisa, futhi kukhuphuka kwe-PPFD. Lapho amalambu amabili abekwe eduze ndawonye, ​​indawo egqamile ithola i-PPFD ephakeme. Ngalezi zimiso, ungaguqula ukusetha kwakho ukufeza i-PPFD ekahle yezitshalo zakho.

3. Ungafunda Kanjani Amashadi Wokukhiqizwa Kwe-PPFD:

Bheka ukuphakama kokuhlola 

- Amanye amashadi alinganiswa ngo-30cm, amanye ku-60cm. Ukuphakama okuhlukile kuholela kumanani e-PPFD ahluke kakhulu.

Hlola ukufana

 - Isibani esihle sokukhanya asivele nje sikhanye, sisakazeka ngokulinganayo.

Bheka ukuthi amanani angakanani ahlukane neshadi. Uma isikhungo singu-1200 μmol / m² / s kodwa imiphetho ingama-500 kuphela, ilungele kangcono izindawo ezincane ezikhulayo.

Isinyathelo 1: Wattage

Ukusuka esihlokweni nasemodeli, singasho ukuthi le mikhiqizo emibili yi-810w ne-1080W ngokulandelana.
Imodeli engu-1080W ngokusobala ine-wattage ephezulu, okusho ukuthi kungasho ukuthi kungaletha amandla aphezulu okukhanya (PPFD). Lokhu kwenza ukuthi ilungele izitshalo ezinezidingo eziphakeme zokukhanya noma izindawo ezitshalwe kakhulu.

Isinyathelo 2: Indawo embozwe
izibani zombili ihlolwe ezindaweni ze-3ft × 3ft (cishe 90cm × 150cm) noma i-150cm × 1500cm, ekhombisa ukuthi zenzelwe amasayizi afanayo wesikhala, njengetende elijwayelekile lesikhathi.

Isinyathelo 3: Ukuphakama kokuhlola
kunezindlela ezimbili zokuhlola: 30cm no-60cm. Uma uqhathanisa, kubalulekile ukuphakama kuyafana, njengokuphakama kuyinto ebalulekile ekulawuleni komabili ama-PPFD kanye nokufana okukhanyayo.

Isinyathelo 4: Ukuhlaziywa kwenani le-PPFD

Usebenzisa i-GL-QB810W njengesibonelo

• Ku-30cm:
  • I-Center Peak: 2005
  • Umehluko ophansi: 295
  → Kunomehluko omkhulu ekusakazweni okukhanyayo phakathi kwesikhungo nemiphetho.

• Ku-60cm:
  • Isikhungo: 1445 • I
  Edge: 402
  -

Ukusuka ekuhlaziyweni okungenhla, singabona cishe ukuthi amanani e-PPFD akhombisa ukusatshalaliswa kokukhanya okungalingani, ngokukhanya okwengeziwe endaweni eyodwa kunenye. Kunomehluko omkhulu phakathi kwesikhungo kanye nemiphetho, okuyisibonakaliso esiqinile sokuthi kungenzeka ukuthi lolu hlobo lwe-PCB lukhula ukukhanya.

Ekugcineni, cabanga ngokuthenga imitha ye-PPFD. Ithuluzi elilula elikuvumela ukuthi ulinganise ukukhanya ezikhundleni ezihlukile. Uzokwazi ukukwazi kahle ukuphakama kwakho okukhanyayo nokuhlukanisa izikhala, okwenza lonke uhlelo lwakho lokukhanyisa luqonde futhi lusebenze kahle

Lapho ukukhanya kukhula, kanjalo nolwazi. Ngiyethemba wonke umuntu uphefumulelwe ngokwabelana!
