Ngokuvuthwa kwetekhnoloji ye-LED, i-lumen ephezulu ye-lumen ekhokelela ityhubhu ngokuthe ngcembe iqhelekile ukubonwa, ngoko ke intengiso ilindele ngakumbi kumandla aphantsi kodwa ngeemveliso eziphezulu ze-lumen.

NgoSeptemba 2013, iJapan ikhanyisa i-Endo Lighting iphakamisa ityhubhu ye-LED enobuchule be-lumen ye-140lm / W, eyabangela ukuqhuma kweengxoxo kunye nehlombe!Nangona ukusebenza kwe-lumen ye-chip ye-LED kunyuswe kakhulu kutsha nje, kodwa ukusebenza kakuhle kwe-lumen kwityhubhu ye-LED nako kuyamangalisa abantu abaninzi.

Kamva malunga nenyanga enye kamva, i-PVTECH evela e-Xiamen yase-China iphakamisa ityhubhu ye-LED ene-145lm / W yokusebenza kakuhle kwe-lumen.Le ityhubhu ye-LED inokubizwa ngokuba yi-artifacts kwishishini le-LED.

Kulula ukwenza ukukhanya okuphezulu kwe-lumen xa ukongeza izixa ze-chip ze-LED.Kodwa kuphela uyilo lolwakhiwo olufanelekileyo kunye nomqhubi osebenza kakuhle kakhulu odibanisa kunye unokuqonda ukusebenza kakuhle kwe-lumen yetyhubhu ye-LED.Oku kwakhona kubonisa ukuba iteknoloji ye-LED yelizwe laseTshayina sele igqithile eTaiwan naseKorea, kwaye isondela ngakumbi kuleyo yaseJapan.
