Imiba emithathu eMikhulu yoShishino loMthombo wokuKhanya kwe-LED kunye nokungaqondi kakuhle okuNtathu

Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe, imithombo yokukhanya ye-LED kwaye ngokuthe ngcembe ayinakwahlulwa kubomi bethu. Namhlanje, utshintshiselwano olutsha kunye noludala, ngokungathandabuzekiyo isikhundla esiphezulu semithombo yokukhanya ye-LED ehlala izibane zemihla ngemihla, yingxaki yoshishino lwe-LED kunye nokuthengwa kwe-LED. Umbuzo, yabelana nawe ngamathandabuzo aziswa yile miba: Ishishini lomthombo wokukhanya kwe-LED imiba emithathu emikhulu yeengxaki zomthombo wokukhanya we-LED 1: ixabiso. Ingxaki yexabiso leemveliso ze-LED ibisoloko ingomnye wemiba ethe yatsala ingqalelo enkulu kwishishini. Ukuba uphezulu, uya kuthathwa njengongekho kufutshane nabantu. Ukuba uphantsi, kuya kuthiwa ungumntu ozihlayo. Ngoko ke, imboni ayinayo umgangatho ocacileyo nocacileyo. “Ukuphakama okanye hayi ”Kwimeko ehlazo, ngelixa ixabiso lemveliso lithintelwe yindleko kunye nemarike, ibe yinto “Ngokukhawuleza kunokwenzeka ”Umbuzo, umnini-shishini uya kuthengisa kangangoko kunokwenzeka, kwaye kwimarike yabathengi, kubonakala ngathi kukho abantu abachitha imali ukuthenga iimveliso. Ingxaki yomthombo wokukhanya kwe-LED 2: umgaqo-nkqubo. I-United States iqalile ukuvala ngokupheleleyo izibane ze-incandescent, eziya kuba lithuba elikhulu lemveliso ye-LED ukukhuphisana kwindawo yemarike, kwaye lo mgaqo-nkqubo wokuthandeka okanye ofihliweyo kwishishini le-LED uye wavela ngokungapheliyo kwiminyaka yamuva. “Intyhefu yomgaqo-nkqubo ”Yenza ishishini le-LED lixhomekeke kakhulu kwinkxaso karhulumente. Nangona wonke umntu eqonda ukuba ishishini liya kuxhomekeka kwimarike yeshishini kwixesha elizayo, uninzi lweenkampani zisalindile kwaye zibone indlela urhulumente aqhuba ngayo kuphuhliso, kwaye ngokukhawuleza zitshintshe ingqwalasela yeshishini. Uninzi lweenkampani ze-LED “Utyheyu ”Iimpawu, cinga ukuba unokuma egxalabeni lesigebenga, ngubani ongayi kuvuma ukuma? Ingxaki yomthombo wokukhanya kwe-LED yesithathu: ingcamango. Lo mbono usemva ubandakanyeka kwiinkalo ezininzi. Ijelo, uyilo, uphawu, ukuthengisa kunye neminye imiba ayinakuphinda ilinganise kwaye icinge ngeekhonsepthi ezindala. Iinkampani eziye zaguquka kwizibane zendabuko zineenzuzo zetshaneli, kodwa kwiitshaneli okanye iiprojekthi zangaphambili, zineenzuzo zamatshaneli okanye iiprojekthi zangaphambili. Uhlaziyo lokuziqhelanisa nalo luyafuneka. Ngabaphi abathengi esijongene nabo? Ngawaphi amajelo abawaziyo ngeemveliso ngawo? Ngawaphi amajelo abazithengayo iimveliso? Namhlanje, ngophuhliso oluqhubekayo lwetekhnoloji eyahlukeneyo, siphatha igama lolu shishino lobugcisa obuphezulu. Ngaphambi komthombo wokukhanya kwe-LED ukuthenga ukungaqondi kakuhle okuthathu, imithombo yokukhanya kwe-LED, enye, kunye nokulindela ubomi benkonzo yangempela kuphezulu kakhulu. Umenzi we-LED ulindele ukuba ubomi be-LED buya kufikelela kwiiyure ze-100,000 ze-MTBF (ixesha lokungaphumeleli okuqhelekileyo, umgangatho wokulinganisa ukukhanya kubenzi bezibane zendabuko). Nangona kunjalo, njengayo yonke imithombo yokukhanya esisiseko, ukuhamba kokukhanya kokukhanya kwe-LED nako kubola ngokuhamba kwexesha. Ngoko ke, nangona ixesha lokukhutshwa kokukhanya kwe-LED linokuba lide, i-MTBF ayisiyiyo yodwa ingqalelo yokumisela ubomi benkonzo. Ukubola kwe-lumens ye-LED kuchaphazeleka kwiimeko ezininzi zokusingqongileyo ezifana nobushushu bendalo, ukufuma kunye nomoya. Impembelelo ye-attenuation engapheliyo iphinda ichaphazeleke kulawulo, ulawulo lwe-thermal, inqanaba langoku, kunye nezinye izinto ezininzi zokuqwalaselwa koyilo lombane. Abathengisi abaninzi banokubonelela abathengi ngolwazi olungenangqondo ngezizathu ezithile xa bethengisa ii-LED, ezibangela ukulahlekisa. Ngokomzekelo, ubomi benkonzo ye-LED malunga neeyure ze-100,000. Iiyure ezingama-100,000 apha zibhekisa. Nangona kunjalo, njengomthombo wokukhanya wokukhanya, ukukhanya kwezibane kunenkqubo yokubola ngokuthe ngcembe kumnyama (njengokukhanya kwelanga, izibane zokulondoloza amandla). Le nkqubo ibizwa ngokuba kukubola kokukhanya. Ngoko ke, xa kuthengwa i-LED, abathengi kufuneka banikele ingqalelo kwisantya sayo sokubola kokukhanya, bangasebenzisi ixesha, kwaye abathengi abayi kulindela kakhulu malunga nobomi bokwenene benkonzo. Umthombo wokukhanya we-LED ukungaqondi ezimbini, thatha i-engile yokukhanya yokwenyani njenge-engile esebenzayo. I-angle ekhanyayo ye-LED ihlukaniswe kwii-angles ezisebenzayo kunye nee-angles zokukhanya zangempela. I-angle phakathi kwe-angle phakathi kolwalathiso lwamandla okukhupha isiqingatha solwalathiso lwamandla e-axial kunye ne-axial ekhupha ukukhanya (indlela) i-angle esebenzayo. Izihlandlo ezibini i-engile (okanye i-semi-power angle) yesiqingatha-i-engile yexabiso yeyona engile yokukhanyisa. I-angle ngaphaya kwe-angle yamandla e-axial, ngenxa yokuba ukukhanya kubuthathaka kakhulu kwisicelo sangempela, akubaleli kwi-angle esebenzayo. Ngoko ke, abathengi kufuneka banikele ingqalelo kwi-angle yokukhanya yangempela yemveliso xa kuthengwa iimveliso. Xa ubala inani leemveliso ezisetyenzisiweyo kwiprojekthi, isekelwe kwi-angle yokukhanya yokwenene. Umthombo wokukhanya kwe-LED ukungaqondi kakuhle kwesithathu, amandla amakhulu, okukhona ukukhanya okuphezulu. Ukukhanya kwe-LED kulinganiswa ngokukhanya okukhanyayo. Ukukhanya okukhupha amandla kubhekiselele kumandla okukhutshwa kokukhanya kwicala lomgca wendlela (kwi-cylindrical luminous pipe ibhekisela kwi-axis yayo), oko kukuthi, umthamo we-optical flux ekhutshwe yi-engile ye-dimensional yeyunithi. Ngenxa yamandla amancinci akhanyayo e-LED ngokubanzi, ukukhanya okukhupha ukukhanya kudla ngokusetyenziswa kwiiyunithi zelizwe. Ngokubanzi, umthombo wokukhanya uya kukhupha ukukhanya kwawo kumacala ahlukeneyo kumacala ahlukeneyo. Ukukhanya okubonakalayo kwemitha yokukhanya ekhutshwe kwi-engile ye-dimensional emithathu yeyunithi kwicala elithile kuthiwa yi-intensity yokukhanya, ekubhekiswa kuyo njengokukhanya kwe-axis. Ukususela kwingcamango yamandla ukuya kumandla ombane ngexesha elifanayo, i-current ikhawuleza, i-current ikhawuleza, umbane mkhulu; umsinga uyacotha, amandla ombane mancinci, okanye ngexesha elilinganayo, okukhona umsinga usenza umsinga, umbane mkhulu. Kwi-LED, amandla amakhulu, aphezulu ukuqaqamba kwemveliso. Ukuthatha ezintathu-ezikhanyayo ezibomvu ze-LED zenkampani ethile ye-elektroniki njengomzekelo, xa ukukhanya kwe-axial yi-1200mcd, okwangoku yi-40mA kunye namandla yi-0.48W; i-LED emhlophe ekhanyayo emithathu ikukukhanya okufanayo, okwangoku yi-18mA, kwaye amandla yi-0.24W kuphela; kunokubonwa ukuba kunokubonwa ukuba kunokubonwa Amandla ezibane ezibini phantsi kokukhanya okufanayo ahlukile. Ngoko ke, abathengi kufuneka banikele ingqalelo ekukhanyeni kwayo kwi-axis xa kuthengwa izibane ze-LED, kungekhona amandla. Zhuhai Co., Ltd. ngumvelisi wamaso wesibane se-LED onenani lamalungelo abenzi belizwe. Iimveliso eziphambili zibandakanya ukukhanya okumfusa kwe-LED, iintsimbi zesibane se-infrared, iintsimbi ze-ultraviolet ze-LED, umbala wesibane se-LED, njl. Ukumelana nokushisa okuphezulu, amandla aphezulu. Sineminyaka eyi-16 yamava e-patch ye-LED.
