Amasu Okubopha Nge-LED: Indlela I-Sunsred Esebenzisa Ngayo Idatha Ye-Spectral Ukuqinisekisa Ukungaguquguquki Kokukhiqizwa Kwesisindo？

Ekukhiqizweni kwamaphaneli okwelapha e-LED anamandla aphezulu, ukufeza ukukhishwa kokukhanya okufanayo kuyinselele enkulu yobunjiniyela. Izinqubo zokwenziwa kwe-semiconductor ngokwemvelo zikhiqiza ukwehluka kokwakheka kwe-wafer kanye nokuhlushwa kwe-dopant. Lokhu kwehluka okuncane kakhulu kubangela ukungafani okulinganiselwe ku-wavelength kanye ne-voltage yangaphambili yama-chip e-LED ngamanye. Ukuze kuxazululwe lokhu, imboni isebenzisa inqubo eyaziwa ngokuthi i-LED binning. Lesi sihloko sihlola ukuthi idatha ye-spectral, etholakala ekuhlanganiseni izilinganiso ze-sphere, isetshenziswa kanjani ukuphatha lokhu kwehlukahluka nokuqinisekisa ukuhambisana komkhiqizo.

Ukubopha ama-LED kuyinqubo yokuhlunga ama-LED ngamaqembu athile, noma ama-bin, ngokusekelwe ezicini zawo zokukhanya kanye nezikagesi. Amapharamitha ayinhloko okubopha ama-LED ubude be-wavelength, ukukhanya kwe-flux, kanye ne-forward voltage.

Ukuze i-photobiomodulation isebenze kahle, ukukhanya kumele kufane ne-biological absorption spectra ethile. Ngisho nokuphambuka okuncane kusuka ku-target wavelength kungashintsha ukujula kokungena kwezicubu kanye nokusebenza kahle kokwelapha. Ngakho-ke, ama-LED ahlelwa ngama-bins amancane e-wavelength, njengezigaba ze-660 nanometer noma i-850 nanometer.

I-flux ekhanyayo ibhekisela enanini eliphelele lokukhanya okubonakalayo okuphumayo. I-voltage yangaphambilini ithinta ukusebenza kahle kukagesi kwesekethe. Ngokuhlanganisa ama-LED ane-flux efanayo kanye namanani e-voltage, abakhiqizi bangaqinisekisa ukuthi wonke amadivayisi eqenjini asebenza ngendlela efanayo ngaphansi kwezimo zokushayela ezifanayo.

Ukunemba kwenqubo yokufaka izimpahla kuncike ngokuphelele ekunembeni kwemishini yokulinganisa. I-integration sphere​ isebenza njengethuluzi eliyinhloko lalo msebenzi.

Uma i-LED ifakwa ngaphakathi kwe-integrating sphere, idivayisi ibamba ukusatshalaliswa kwamandla okugcwele kwe-spectral. Lolu lwazi lunikeza ubude be-peak kanye ne-total radiant flux. Ngaphandle kwalokhu kulinganisa okuqondile, akunakwenzeka ukuhlukanisa i-LED ibe yi-bin efanele.

I-Sunsred isebenzisa ukuhlolwa kwe-sphere okuhlanganisiwe kweqoqo ngalinye lama-lamp beads angenayo. Idatha ye-spectral iyaqoshwa futhi ihlaziywe. Ngokusekelwe kulolu lwazi, ama-LED ahlukaniswa ngama-bin athile. Lokhu kuqinisekisa ukuthi izingxenye ezihlangabezana nemininingwane yomklamo kuphela ezikhethwayo ukuze zihlanganiswe.

Inzuzo engokoqobo yokufaka i-binning iyabonakala ngesikhathi sokuhlanganiswa kwephaneli yokwelapha.

Ngokugcwalisa iphaneli eyodwa kuphela ngama-LED avela kubude obufanayo be-wavelength kanye nama-flux bins, i-Sunsred iqinisekisa ukuthi ukusatshalaliswa kokukhanya kuyo yonke indawo kuyafana. Lokhu kuqeda izinkinga ezifana nokufiphala kombala noma izindawo ezishisayo, lapho izindawo ezithile zephaneli zibonakala zikhanya noma zihlukile ngombala kwezinye.

Ukubopha futhi kuqinisekisa ukuthi ikhasimende elithenga iphaneli namuhla lithola izici ezifanayo ze-spectral njengephaneli elithengiwe ezinyangeni kamuva. Lokhu kuvumelana kubalulekile ekusetshenzisweni kwezokwelapha lapho kudingeka khona umthamo ojwayelekile.

Ukufaka i-LED binning akuyona nje indlela yokuhlunga; kuyindlela ebalulekile yokulawula ikhwalithi. Kuguqula ukuguquguquka kwe-semiconductor eluhlaza kube yingxenye ebikezelwayo nejwayelekile. Ngokusebenzisa idatha ye-sphere ukushayela inqubo yokufaka i-binning, abakhiqizi bangaqinisekisa ukuthi umkhiqizo wokugcina uletha ukukhanya okuqhubekayo, okuthembekile, nokuphumelela ekwelapheni.

Ukuqaliswa kwe-Sunsred kwezinqubo eziqinile zokubopha, okusekelwa ukuhlolwa okuphoqelekile kokuhlanganisa i-sphere kweqoqo ngalinye lama-lamp beads, kubonisa ukuzibophezela kobunjiniyela obunembile. Le ndlela ehlelekile iqinisekisa ukuthi yonke iphaneli yokwelapha ekhiqizwayo ihlangabezana nezindinganiso eziphakeme ezifunwa yizimboni zezokwelapha nezempilo.
