Isibane sobungqina bokuqhuma kwe-LED luhlobo lwesibane sobungqina bokuqhuma.Umgaqo wayo ufana nesibane sobungqina bokuqhuma, ngaphandle kokuba umthombo wokukhanya ungumthombo wokukhanya we-LED, obhekiselele kwisibane esinamanyathelo athile ahlukeneyo athatyathiweyo ukukhusela indawo engqongileyo yothuli kunye negesi ekukhanyeni.Izibane ze-LED ezikhusela ukuqhuma okwangoku zizibane ezigcina amandla okuqhuma, ezisetyenziswa kwiikhemikhali zepetroli, imigodi yamalahle, izityalo zamandla, izikhululo zegesi kunye nezinye iindawo.
Sonke siyazi ukuba izibane zobungqina bokudubula ze-LED zineziphumo ezilungileyo zokonga amandla kunye nokuqaqamba okulungileyo.Ke yintoni echaphazela ubomi bezibane ze-LED ezingaqhushumba, kwaye ukugcinwa kunokuzisa njani iingenelo?
Izinto ezininzi ezichaphazela ubomi bezibane ze-LED ezibonisa ukuqhuma:
1. Umgangatho we-wick yimeko ephambili emisela ubomi besibane se-LED esingaqhumi.
Kwinkqubo yokwenziwa kwee-chips ze-LED, ezinye izinto ezingcolileyo ze-ion, iziphene ze-lattice kunye nezinye iinkqubo zobuchwepheshe ziya kuchaphazela ubomi babo.Ngoko ke, ukusetyenziswa komgangatho ophezulu wee-wicks ze-LED yimeko ephambili.
Isibane sikaKeming sobungqina bokudubula sithatha intsimbi yesibane esine-LED ephezulu esilinganisa ilume kunye noyilo lwetshiphu enkulu.Umthombo wokukhanya we-LED owenziwe ngokukodwa unombono ofanayo, ukuhanjiswa kokukhanya okuphezulu kunye nokukhanya okuphantsi.
2. Uyilo lwesibane ngumba ophambili ochaphazela ubomi bezibane ze-LED ezinokuqhuma
Ukongeza kokudibana nezinye izibonakaliso zesibane, idizayini yesibane esifanelekileyo ngumba ophambili wokuchitha ubushushu obuveliswayo xa i-LED ikhanya.Umzekelo, izibane ezidityanisiweyo zomthombo wokukhanya kwimarike (eyodwa 30 W, 50 W, 100 W), umthombo wokukhanya kwezi mveliso kunye nenxalenye yokunxibelelana kobushushu besiteshi sobushushu ayigudi, ngenxa yoko, ezinye iimveliso zibangela. ukukhanya emva kweenyanga ezi-1-3 zokukhanyisa.Ukubola kungaphezu kwama-50%.Emva kokuba ezinye iimveliso zisebenzisa ityhubhu yamandla aphantsi malunga ne-0.07 W, ngenxa yokuba akukho ndlela ifanelekileyo yokuchitha ubushushu, ukukhanya kubola ngokukhawuleza.Ezi zintathu zingezomveliso zinomxholo ophantsi wobugcisa, ixabiso eliphantsi kunye nobomi obufutshane.
3. Umbane wesibane ubaluleke kakhulu kubomi besibane sobungqina bokudubula kwe-LED
Ingaba unikezelo lwamandla lwesibane lunengqiqo luya kuchaphazela ubomi baso.Ngenxa yokuba i-LED sisixhobo esiqhutywa ngoku, ukuba umbane okhoyo ngoku uguquguquka kakhulu, okanye i-frequency spikes yamandla iphezulu, iya kuchaphazela ubomi bomthombo wokukhanya kwe-LED.Ubomi bombane ngokwawo buxhomekeke ekubeni uyilo lonikezelo lwamandla lunengqiqo.Kwisiseko soyilo lonikezelo lwamandla olufanelekileyo, ubomi bokunikezelwa kwamandla buxhomekeke kubomi bamacandelo.
4. Impembelelo yobushushu be-ambient kubomi bezibane ze-LED ezibonisa ukuqhuma
Ubomi obufutshane obukhoyo bezibane ze-LED ikakhulu ngenxa yobomi obufutshane bokunikezelwa kwamandla, kwaye ubomi obufutshane bokunikezelwa kwamandla ngenxa yobomi obufutshane be-electrolytic capacitor.Olunye uphawu lwesalathiso sobomi be-electrolytic capacitors kukuba kufuneka lubonise ubomi phantsi kobushushu bemekobume yokusebenza ukuba zingaphi iidigri, kwaye ngokuqhelekileyo lucaciswa njengobomi obuphantsi kobushushu be-ambient ye-105 ℃.Ukunciphisa ubushushu be-ambient, ixesha elide ubomi benkonzo ye-capacitor.Nokuba i-electrolytic capacitor eqhelekileyo eneeyure eziyi-1,000 inokufikelela kwiiyure ezingama-64,000 kwiqondo lobushushu obungama-45 ° C, elanele isibane esiqhelekileyo se-LED esinobomi obuqhelekileyo beeyure ezingama-50,000.Yisebenzise.
Ukugcinwa kwemihla ngemihla kwezibane ze-LED ezikhusela ukuqhuma:
Sithenga isibane esilungileyo sokukhanya kwe-LED singasetyenziselwa iminyaka emithathu, kodwa ngokuqhelekileyo awuhoyi ukugcinwa kwesibane sobungqina be-LED, ngoko unokusisebenzisa iminyaka emibini kuphela, elingana sichitha imali eninzi, sisenza njani isibane sobungqina bokudubula kwe-LED Ubomi obude bungundoqo, makhe sithethe ngokufutshane ngezinto ezimbalwa ezingezantsi:
1. Ukucoca rhoqo uthuli kunye nolunye udoti kwizindlu zesibane (ukuba alucocwanga ixesha elide, uthuli lunamathela kwisibane ukuze luthintele ubushushu obukhutshwa sisibane, nto leyo ebangela ukuba ubushushu bungacinywa. Isibane sobungqina bokudubula kwe-LED Isiphumo esihle sokutshatyalaliswa kobushushu), ukuchithwa kakuhle kobushushu yinto ebalulekileyo yokwandisa ubomi be-LED.
2. Ukulungiswa kwangethuba kunye nokuvalwa kwezibane.Kunconywa ukuba izibane zingasebenzi ngokungaphazamiseki kwiiyure ezingama-24, kuba ukushisa kwezibane kuya kunyuka ngokuthe ngcembe ngexesha lomsebenzi ongaphazamisekiyo.Ukuphakama kweqondo lokushisa, impembelelo enkulu kubomi besibane.Ukuphakama kweqondo lobushushu, bufutshane ubomi besibane..
3. Isigqubuthelo sokuhambisa ukukhanya sicoca rhoqo uthuli kunye nezinye i-debris ukuqinisekisa umphumo wokuhambisa ukukhanya
4. Jonga rhoqo i-voltage yesiphaluka.Ukuba i-voltage ayizinzile, isiphaluka kufuneka sigcinwe kwaye silungiswe.
5. Ubushushu be-ambient yezibane ze-LED zobungqina bokuqhuma akufanele bube ngaphezu kwama-degrees angama-60, kwaye ubomi benkonzo bunokufinyezwa ngokuthe ngqo nge-2/3 ukuba bungaphezulu kwama-60 degrees.
6. Izibane kufuneka zivulwe rhoqo ngexesha lokusetyenziswa kwesiqhelo.
