Ibanga lokuxhuma lezibani zemikhosi zokuhlobisa ze-LED

Naka ibanga lokuxhuma kwezibani zokuhlobisa ze-LED zamaholide: Ngokuvamile, ibanga lokuxhuma izibani zokuhlobisa iholide zochungechunge lwezibani zokuhlobisa iholide zingamamitha angu-20, futhi ibanga lokuxhuma lika-5050 uchungechunge lwezibani zokuhlobisa iholide zingamamitha angu-15. Uma ibanga lokuxhuma lidluliwe, kulula ukukhiqiza ukushisa, okuzothinta impilo yesevisi ngesikhathi sokusetshenziswa. Ishubhu yengilazi ingaba nemibala noma inemibala, futhi udonga lwangaphakathi lungabuye luboshwe nge-phosphor.

Indlela yokuxhuma amandla okukhanya okuhlobisa kwe-LED: I-voltage evamile yomugqa wesibani se-LED yi-DC 12V, edinga ukunikwa amandla ugesi oshintshayo. Usayizi wokunikezwa kwamandla unqunywa ngokuya ngamandla nobude bokuxhuma komugqa we-LED. Uma ungafuni ukuthi umugqa wokukhanya we-LED ngamunye ulawulwe ukunikezwa kwamandla kagesi owodwa, ungathenga ugesi oshintshayo onamandla amakhulu uma kuqhathaniswa nawo wonke amandla okunikezwa kwamandla, bese uxhuma zonke izisetshenziswa zamandla okufakwayo komugqa wokukhanya we-LED ngokuhambisana (uma i-diameter yocingo inganele, ungayinweba ngokuhlukana), ugesi oshintshayo oyinhloko Hlanganisa.

I-silhouette yedolobha lasemini ichazwa ngokuma, umbala nesithunzi semiphetho yesakhiwo, futhi ebusuku izibani zokuhlobisa ze-LED zemikhosi yedolobha ziveza ngokucacile i-silhouette yedolobha, iyenza ihluke ezindaweni ezizungezile. Uma ubheka idolobha kusukela ekuphakameni ebusuku, i-silhouette iphelele futhi icacile, ebonisa intuitively ukuma nesikali somuzi. Ngemuva kokuthi ithubhu yesibani ikhishwe kancane, igcwele igesi eyodwa noma ngaphezulu ye-inert njenge-neon, i-argon, i-helium, njll, futhi inani elincane le-mercury lingagcwaliswa.

Ngokusho kombala wengilazi ye-tubular, imvelo ye-fluorescent powder kanye negesi yokugcwalisa, ungathola izibani ezihlukahlukene zeholide ezinemibala ehlukene yokukhanya. Amashubhu engilazi okuhlobisa emikhosini afakwe ama-electrode ethusi kuzo zombili iziphetho futhi aphathwa ngamakhemikhali ukuze amelane nokugqwala. Izintambo ezikhishwe kuma-electrode kanye namandla kagesi zibizwa ngokuthi umkhondo, okudingeka ukuthi zibe nezici ezifanayo zokunweba ezishisayo njengengilazi. Ukuze uvimbele ingilazi ukuthi ingaqhekeki, ama-alloys e-nickel ngokuvamile asetshenziswa. Ubukhazikhazi
