I ka makahiki 2019-1911 i hala iho nei, he "kaumaha" no kaLEDʻoihana, ʻoi aku ka maikaʻi ma ke kahua o nā pahu LED. Ua uhi ʻia ka mana ma waena o ka ʻeleʻele a me ka haʻahaʻa haʻahaʻa a me ka emi ʻana o nā kumukūʻai i loko o ka puʻuwai o nā mea hana chip.

Hōʻike ka ʻikepili noiʻi GGII i ka nui o ka nui o nā chip LED o Kina ma kahi o 23.8 biliona yuan ma 2019 a me 27 biliona yuan ma 2020. E komo ka kaulahao ʻoihana LED i kahi manawa ulu haʻahaʻa i nā makahiki e hiki mai ana.

I ka makahiki 2019, ua koʻikoʻi ka overcapacity o ka chip a ua haʻahaʻa loa ka helu hana. Ua hele kekahi mau ʻoihana i ka waihona a ʻoki i nā kumukūʻai, a hāʻule ke kumukūʻai e 30-50%. Nui nā ʻoihana chip LED i hapa i kā lākou loaʻa kālā a i ʻole nalo kālā.

Hōʻike pū ka ʻikepili kālā i kēia. Mai ka hiʻohiʻona o nā mea hana chip nui ʻē aʻe e like me Sanʻan optoelectronics, Aoyang Shunchang, jucan optoelectronics, Huacan optoelectronics, Qianzhao optoelectronics a me Shilan micro, ka mea i hōʻike i ka hōʻike makahiki 2019 a me ka wānana hana 2019, ua emi ka loaʻa kālā i nā degere like ʻole. -ma ka makahiki.

Eia nō naʻe, i ke alo o ka "pilikia" e hiki mai ana o ka mākeke chip, ua hana pū nā ʻoihana i nā hoʻomākaukau kūpono, hoʻomaikaʻi i kā lākou ʻano huahana i kēlā me kēia, a ua hoʻāʻo e hoʻopili i nā ʻāpana mākeke.
