'Blue LED' Yapera? 'Violet LED' Era Yauya Chinyararire

Pakutanga, nhandare yebhuruu ye LED inovhenekera baba \u0026 mdash; \u0026 mdash; Shuji Nakamura GaN aenda kumusangano akaratidzira shanduko yesimba, achishandisa bhuruu ye LED chena tekinoroji ye LED inopera nekukurumidza. Izvo zvakakonzera nhaurirano ine moyo yeindasitiri. backpfrontp Vamwe vaongorori vakaratidza kuti yepakutanga kugadzirwa yebhuruu LED uye kuwana Nobel Prize muFizikisiki muna 2014 Shuji Nakamura, zvino akapidigura tsvakurudzo yavo, zvichida kunze kambani yake yakatangwa Soraa chikuru kusunda yepepuru LED nhandare chiedza kushambadza. (Sekuziviswa kwandakaita kuti kambani iyi purofesa muUnited States musha weSoraa pamwe chete nemapurofesa matatu UCSB semubatsiri (co-founder) akagadzira LED venture) backpfrontp asi kune vamwe vanhu muindasitiri vakaratidza rutsigiro. Shuji Nakamura, semubayiro weNobel masayendisiti anofanirwa kunge aine maitiro ehutsika uye maitiro ehunyanzvi, nekuti akaona tarisiro huru yepepuru yakakwirira simba LED mafashamo magetsi , ichaisa yepepuru LED tsvakurudzo-based makambani. Hongli Opto-electronic product director Wang Gaoyang akadaro. backpfrontp zvakadaro, yakagara yakakurumbira semusayendisiti, tinotendawo kuti akaita kutonga kunofanira kubva pakunzwisisa kwake uye kutanga nzvimbo yebhuruu yayo LED maonero anotarisa akaipa, chero bedzi paine tsigiro yezvinyorwa, zvakasikwa, ine rationality. Asi \u0026 lsquo; blue LED \u0026 rsquo; kwete, violet LED uye chii chinonzi Baba backp blue 1000W LED mafashamo magetsi e \u0026 mdash; \u0026 mdash; Shuji Nakamura backpfrontp Maererano nehuwandu, zvakanakira zvepepuru LED zvakanyanya nekuda kwe:? Yakakwira CRI uye yakakwira inopenya inoshanda maitiro maviri. backpfrontp uko yakakwira color rendering index inonyanya kuratidzwa nenzira yekuwana yepepuru LED chena LED kuburikidza nepepuru LED inonakidza phosphor kuwana mwenje webhuruu, uye kusimba kwepamusoro kwechiedza chebhuruu hakuna kunyanya kukwira, uye yepepuru LED inogona kuburitsa uhwu hunoonekwa hurefu hwechiedza chese mukati, uye nekudaro hune ruvara rwakanyanya kupa indekisi, hunogona kuwana hunhu hwakafanana nechiedza chezuva chichena.
