Amaso e-LED amele ii-diode ezikhupha ukukhanya.
Umgaqo wayo oqaqambileyo kukuba i-PN junction terminal voltage yenza umqobo othile onokuthi ubekho, xa umbane ocalanye we-bias wangaphambili wongezwa, umqobo onokuthi uhle, kwaye uninzi lwabathwali kwiindawo ze-P kunye no-N basasazeke omnye komnye. Ekubeni ukuhamba kwe-electron kukhulu kakhulu kunomngxunya wokuhamba, inani elikhulu lee-electron liza kusasazeka kwi-P-region, ebandakanya inaliti yabathwali abambalwa kwi-P-region. Ezi electron zidibanisa kunye nemingxuma kwi-valence band, kwaye amandla aphumayo akhululwa njengamandla okukhanya.
Iimpawu zayo zezi zilandelayo:
1. Umbane: Iintsimbi zesibane se-LED zisebenzisa umbane ophantsi kwamandla ombane, amandla ombane ombane phakathi kwe-2-4V. Ngokweemveliso ezahlukeneyo, iqhutywa ngumbane okhuselekileyo kunombane ophezulu wombane, ofanelekileyo ngakumbi kwiindawo zoluntu.
2. Okwangoku: ukusebenza kwangoku ngu-0-15mA, kwaye ukukhanya kuya kukhanya ngokunyuka kwangoku .
3. Ukusebenza kakuhle: I-80% yokusetyenziswa kwamandla angaphantsi kunezibane ze-incandescent ezinokukhanya okufanayo.
4. Ukusetyenziswa: Iyunithi nganye ye-chip ye-LED yi-3-5mm yesikwere, ngoko inokulungiswa kwiimo ezahlukeneyo zezixhobo, kwaye ifanele indawo eguqukayo.
5. Ixesha lokuphendula: Ixesha lokuphendula kwesibane sayo se-incandescent yinqanaba le-millisecond, kwaye isibane se-LED sikwinqanaba le-nanosecond.
6. Ungcoliseko lokusingqongileyo: Akukho mekyuri yentsimbi eyingozi.
7. Umbala: Umbala unokutshintshwa ngoku, ukhokelwa ngendlela yokuguqulwa kweekhemikhali, ulungelelanise isakhiwo sebhendi kunye ne-gap ye-band yezinto eziphathekayo, ukufezekisa ukukhanya obomvu, ophuzi, oluhlaza, ohlaza okwesibhakabhaka, o-orange onemibala emininzi. Ngokomzekelo, xa i-low current ibomvu i-LED, ngokunyuka kwangoku, inokujika i-orenji, iphuzi, kwaye ekugqibeleni ibe luhlaza.
Iiparamitha zayo zichazwe ngolu hlobo lulandelayo:
1.Ukukhanya
Ixabiso lamaso e-LED linxulumene nokuqaqamba.
Ukukhanya okuqhelekileyo kwamaso yi-60-70 lm. Ukukhanya ngokubanzi kwesibane sebhalbhu yi-80-90 lm.
Ukukhanya kwe-1W ukukhanya okubomvu ngokuqhelekileyo yi-30-40 lm. Ukukhanya kwe-1W ukukhanya okuluhlaza ngokuqhelekileyo yi-60-80 lm. Ukukhanya kwe-1W ukukhanya okutyheli ngokuqhelekileyo yi-30-50 lm. Ukukhanya kwe-1W ukukhanya okuluhlaza ngokuqhelekileyo yi-20-30 lm.
Qaphela: Ukukhanya kwe-1W yi-60-110LM. Ukukhanya kwe-3W ukuya kuthi ga kwi-240LM. I-5W-300W i-chip edibeneyo, kunye ne-series / parallel package, ngokukodwa kuxhomekeke kubungakanani bangoku, i-voltage.
I-LED lens: i-PMMA, i-PC, i-glass optical, i-silica gel (i-soft silica gel, i-silica gel enzima) kunye nezinye izinto eziqhelekileyo zisetyenziselwa i-lens ephambili. Inkulu i-angle, iphezulu ukukhanya kokukhanya. Nge-lens encinci ye-Angle ye-LED, ukukhanya kufuneka kube kude.
2. Ubude bamaza
Ubude obufanayo kunye nombala kwenza ixabiso eliphezulu.
Ukukhanya okumhlophe kwahlulwe kumbala ofudumeleyo (ubushushu bombala 2700-4000K), umhlophe omhlophe (ubushushu bombala 5500-6000K) kunye nomhlophe obandayo (ubushushu bombala ngaphezu kwe-7000K).
Ukukhanya okubomvu: ibhendi 600-680, apho i-620,630 isetyenziselwa izibane zesiteji kwaye i-690 isondele kwi-infrared.
I-Blu-ray: I-Band 430-480, apho i-460,465 isetyenziswa ikakhulu kwizibane zeqonga.
Ukukhanya okuluhlaza: I-Band 500-580, apho i-525,530 isetyenziselwa izibane zeqonga.
3. I-engile ekhanyayo
Iiledi ngeenjongo ezahlukeneyo zikhupha ukukhanya kwii-engile ezahlukeneyo. I-Angle ekhethekileyo ekhanyayo ibiza kakhulu.
4. Ikhono le-Antistatic
Isakhono se-Antistatic sesibane sesibane se-LED sinobomi obude, ngoko ke ixabiso liphezulu. Ngesiqhelo ngaphezu 700V amaso isibane LED antistatic zingasetyenziselwa izibane LED.
5. Ukuvuza kwangoku
Amaso isibane se-LED yindlela enye yomzimba okhanyayo okhanyayo. Ukuba kukho i-reverse yangoku, ibizwa ngokuba yi-leakage, ukuvuza kwangoku amaso isibane se-LED inobomi obufutshane kunye nexabiso eliphantsi.
Eurbornivelisa izibane zangaphandle eTshayina. Sihlala sikhetha uphawu oluhambelanayo ngokwezibane kwaye sizame konke okusemandleni ethu ukwenza iimveliso zigqibelele.
