ʻeleʻele oNā pale hōʻike LEDhe mea maʻamau.I kēia lā, e nānā kākou i nā kumu nui o kona ʻeleʻele.
1. Sulfurization, chlorination, a me ka bromination
ʻO ka ʻāpana kala kala ma ka pale hōʻike LED e hoʻohua i ke kālā sulfide i ka wā e hoʻopili ai me ke kinoea sulfur, a i ka wā e hoʻopili ai me ka chlorine a me ke kinoea bromine acidic, e hoʻohua mai ia i ka halide kālā photosensitive. ʻo ke kumu kukui e ʻeleʻele a hāʻule.Hiki ke loaʻa ka sulfur/chlorine/bromination o nā kumu kukui i kēlā me kēia pae o ka hana, mālama, ʻelemakule, a me ka hoʻohana ʻana i nā kumu kukui LED a me nā kukui.Ma hope o ka ʻike ʻia ʻana me ka sulfur/chlorine/bromination ma muli o ka ʻeleʻele o ke kumu kukui, pono ka mea kūʻai aku e koho i kahi hoʻolālā hoʻoneʻe sulfur kikoʻī e pili ana i ke kahua kahi e kū ai ka sulfur/chlorine/bromination.I kēia manawa, ʻo nā papahana ʻike sulfur/chlorine/bromine i hoʻokumu ʻia e Jinjian: ke kukui sulfur/chlorine/bromine (me ka hale i kūkulu ʻia.lako ikehu), kukui sulfur/chlorine/bromine (koe i waho o ka mana lako), mana lako sulfur/chlorine/bromine, mea kōkua sulfur/chlorine/bromine, hale hana sulfur/chlorine/bromine, hale hana kukui sulfur/chlorine/bromine, a reflow soldering hale hana sulfur/chlorine/bromine.Ma muli o ke kinoea i loko o ka sulfur, chlorine, a me ka bromine hiki ke komo i loko o ke kumu kukui ma o nā āpau i ke silicone a i ʻole nā brackets, ua hoʻokumu pū ʻo Jinjian i kahi hoʻolālā nānā ea e kōkua hou i nā mea kūʻai aku e hoʻomaikaʻi i kā lākou mau koi no nā kumu kumu kukui.
2. ʻOkiʻi
Hoʻopili maʻalahi ke kālā me ka oxygen ma nā wahi wela a me ka haʻahaʻa kiʻekiʻe, e hana ana i ka ʻeleʻele kala kala.Ma hope o ka hōʻoia ʻana ʻo ke kumu o ka ʻeleʻele ʻana o ke kumu kukui he oxidation o ka papa plating kālā, e ʻōlelo ʻo Jin Jian i ka mea kūʻai aku e hana hou i ka nānā ʻana i ka ea ma ke kumu kukui a me ke kukui e hoʻopau i ke ala o ka infiltration moisture.
3. ʻO ka hoʻolāʻau
Ma muli o ka ʻike, nā hemahema waiwai i nā kumu waiwai nui ʻeono o nā kumu kukui LED (chips, brackets, solid crystal glue, bonding wires, fluorescent powder, and packaging glue) a me ke kaʻina hana i nā kaʻina hana hoʻopihapiha nui ʻekolu (paʻa kristal, wiring, a me ka hoʻopili ʻana) hiki ke alakaʻi i nā wela kiʻekiʻe loa i ke kumu kukui, e hoʻoulu ai i ka ʻeleʻele kūloko a i ʻole holoʻokoʻa a me ka carbonization o ke kumu kukui.ʻO ka hoʻolālā hoʻoheheʻe wela kūpono ʻole o nā kukui LED, haʻahaʻa haʻahaʻa thermal conductivity o nā mea hoʻoheheʻe wela, hoʻolālā mana kūpono ʻole, a me ka nui o ka reflow soldering defects hiki ke kumu i ka carbonization o ke kumu kukui.No laila, i ka wā Jinjian preliminarily hōʻoia i ke kumu o ka blackening o ka malamalama kumu he carbonization, e olelo aku i ka mea kūʻai mai e hahai i ke kukui LED kumu a kukui hemahema ana ana ala ala, dissect ke kumu malamalama / kukui, a ike i ke kumu o ka hemahema a i ole. pale wela kiʻekiʻe.
4. ʻAʻole pili i nā kemika
ʻO ka ʻeleʻele o nā kumu kukui LED ma muli o ka hoʻohaumia ʻana i nā kemika, a ʻike pinepine ʻia kēia ʻano ʻeleʻele i nā kukui i hoʻopaʻa ʻia me ka liʻiliʻi a ʻaʻohe kahe o ka ea.
Ke hālāwai mākou i kahi kūlana i ʻeleʻele ai ka pale hōʻike LED, hiki iā mākou ke noiʻi i nā kumu i kēlā me kēia a hana i nā hoʻoponopono.
