'Ala ʻulaʻula' kahiko? Ua hiki malie mai ka Era 'Violet LED'

Ma mua, ke kukui LED kahua pāʻani makua \u0026 mdash; \u0026 mdash; Ua haʻi ʻo Shuji Nakamura GaN i ka wā e hele ai i ka seminar i ka hoʻololi ʻana i ka ikehu, me ka hoʻohana ʻana i ka ʻenehana LED keʻokeʻo LED polū e nalowale koke a ma hope paha. ʻO ka mea i hoʻoulu i kahi kūkākūkā ola o ka ʻoihana. backpfrontp Kekahi kanaka kālailai ua kuhikuhi mai i ka mea mua o ka uliuli LED a loaʻa i ka Nobel Prize in Physics ma 2014 Shuji Nakamura, i kēia manawa hoʻokahuli i kā lākou noiʻi, malia paha mai loko o kona hui ponoi i hoʻokumu 'ia Soraa nui pana poni LED kahua hoʻolaha kukui publicity. (E like me kaʻu i hoʻomaopopo ʻia he polopeka ka hui ma ke kauhale ʻo Soraa ʻAmelika Hui Pū ʻIa me ʻekolu mau polopeka UCSB ma ke ʻano he co-founder (co-founder) i hoʻokumu ʻia ʻo LED venture) backpfrontp akā aia kekahi poʻe i ka ʻoihana i hōʻike i ke kākoʻo no Shuji Nakamura, e like me ka Nobel Prize 'epekema pono e me ka kiʻekiʻe ethical hae a me ka 'oihana hana, no ka mea, ua ike nui prospects poni kiʻekiʻe mana LED kahawai kukui , e kau i ia poni LED noiʻi-ma muli hui. Ua ʻōlelo ʻo Hongli Opto-electronic product director Wang Gaoyang. backpfrontp naʻe, ua lōʻihi kaulana e like me ka 'epekema, mākou no hoi manaoio i hana ia i ka hoʻokolokolo 'ana e ma muli o kona hoomaopopo ana a me ka hoʻomaka wahi no kona uliuli LED ka nānā 'ana i ka ino, e like me ka mea he kākoʻo theoretical, maoli, he rationality.
