Ua ʻike ka ʻoihana pale LED i ka ulu nui ʻana a ua manaʻo ʻia ʻo ia kekahi o nā ʻāpana koʻikoʻi a hoʻohiki i ka mākeke honua. ʻO nā pahu kukui LED nā mea pono i lokoNā pale LEDhe kuleana koʻikoʻi ia i ka hōʻoia ʻana i ka maikaʻi o nā hōʻike. No ka hoʻomaopopo piha ʻana i nā pahu kukui LED, he mea nui e noʻonoʻo i nā helu i loko o ka ʻoihana.
Kuhi ʻia ka nui o ka mākeke honua no nā kukui kukui LED e ulu e 9.6%, a hiki i 240.9 miliona USD e 2028, mai ka 2022 pae. Hōʻike kēia ulu nui i ka hana koʻikoʻi o kēia mau pahu kukui i ka ʻoihana pale LED.
Inā ʻoe e hoʻolālā e hoʻolilo i nā hōʻike LED, ʻo ka hoʻomaopopo ʻana i nā lei kukui LED he mea nui. E ʻimi pū i nā ʻano ʻano leʻaleʻa LED i loaʻa.
He aha nā kukui kukui LED?
ʻO ka hoʻomaopopo ʻana i ke ʻano o nā pahu kukui ka hana mua i ka ʻike ʻana i ke kuleana o kēia mau mea e pāʻani ai i nā pale LED. ʻO nā pahu kukui LED, i ʻike ʻia ʻo nā pahu kukui a i ʻole nā emitters, ʻo ia nā semiconductors liʻiliʻi e manaNā huahana LEDe like me nā hōʻike LED. Hiki i kēia mau semiconductor i nā LED ke hoʻokuʻu i ke kukui a hana maʻamau ʻia mai nā mea e like me:
- Arsenic
- Galium
- Phosphorus
ʻO ke kala i hoʻokuʻu ʻia e ka LED e pili ana i ka mea i hoʻohana ʻia i ka semiconductor. ʻO nā kala maʻamau ka ʻulaʻula, melemele, ʻōmaʻomaʻo, a me ka uliuli. ʻO kēia mau kukui kukui LED ke kī i nā pale LED kiʻekiʻe. Hele mai lākou i nā ʻano like ʻole, e like me:
- Retangle
- huinaha
- Poʻapuni
- ʻaoʻao
- Micro
- ʻAlohilohi o ka ʻili
Loaʻa i kēlā me kēia pahu kukui ʻelua mau pilina e pili ana i nā uku maikaʻi a maikaʻi ʻole i ka semiconductor. Lawe ka anode i ka hoʻopiʻi maikaʻi, aʻo ka cathode e lawe i ka uku ʻino. Hiki iā ʻoe ke ʻike maʻalahi i kēia ma o nā hōʻailona (+) a me (-) i hoʻopaʻa ʻia ma luna o lākou.
Nā ʻano o nā ʻano hana hoʻoheheʻe LED
Hoʻopili ʻia nā pahu kukui LED ma nā ʻano like ʻole, hiki ke hoʻopili i kā lākou hana a me ka hāʻawi ʻana i ka maikaʻi o nā hōʻike LED. ʻO ka maʻamau, ua uhi ʻia lākou me kahi diffuser a i ʻole lens, e ʻae i ka semiconductor e hoʻokele i nā ʻano e like me ka ikaika a me ke kuhikuhi o ka mālamalama. Hoʻokomo pinepine ʻia nā pahu kukui LED ma luna o kahiPCB (Printed Circuit Board).
ʻO nā ʻano hana kaʻina hana maʻamau LED maʻamau ʻo DIP (Direct In-line Package),SMD (Surface-mount Diodes), aCOB (Chip on Board). Loaʻa i kēlā me kēia ala kona pono pono'ī e pili ana i ka hana, ke kumukūʻai, a me ka hoʻohana.
DIP (Poloke Laina pololei)
ʻO nā pahu kukui LED i hoʻohana ʻia ma ke ʻano DIP e lilo i mea maʻamau i ka mākeke a me ka ʻoihana pale LED. Eia naʻe, hāʻawi lākou i kekahi mau pono a me nā hiʻohiʻona:
- Kūpono no ka hoʻohana ʻana i waho
- Kiʻekiʻe olinolino
- Paʻa maikaʻi loa
- Liʻiliʻi ka nānā ʻana i ke kihi kihi (H/V 120/60 degere)
SMD (Surface-mount Diodes)
ʻO ke kaʻina hana SMD ka mea kaulana loa ma waena o nā ʻano kukui kukui LED āpau, ʻoi loa i ka ʻoihana hōʻike LED. Aia kekahi mau hiʻohiʻona maʻamau o nā SMD:
- Hana maʻalahi a maʻalahi
- Kumukuai pono
- ʻO ka huina nānā ākea (H/V 120/120 degere)
- Loaʻa i nā liʻiliʻi liʻiliʻi
COB (Chip on Board)
ʻO ka mea hope loa, ʻo Chip On Board (COB) e pili ana i ke ʻano hana kahi e kau pono ʻia ai nā pahu kukui LED ma ka papa kaapuni, ʻaʻole like me ke ʻano maʻamau kahi e kau ʻia ai nā pahu kukui LED ma kahi kumu. Ua ʻike ʻia kēia ʻano hana no kēia:
- ʻO ka inoa inoa Glop-top
- ʻO ka hoʻokaʻawale kūpono o ka chip
- Palekana o kona mau pili
Nā hiʻohiʻona o nā lei kukui LED
I ka hoʻomaopopo ʻana i nā pahu kukui LED, aia kekahi mau hiʻohiʻona i kaʻana like ʻia e nā pahu maʻamau:
- Hoʻonohonoho laina chip
- Māmā (e like me 1 mg no kēlā me kēia LED)
- ʻili i mālama ʻia i ka noe
- ʻAlohilohi pale mālie
- Puke ʻeleʻele RGB
Nā Lei kukui LED vs. LED (Light-emitting Diodes)
ʻO nā pahu kukui LED a me nā kukui-emitting diodes (LEDs) pili i nā ʻāpana like ʻole, me kekahi mau hiʻohiʻona like a me nā ʻokoʻa nui. Eia ka hoohalike ana o ko lakou mau ano.
| Nā hiʻohiʻona | Lei kukui LED | Nā Diodes Māmā (LED) |
|---|---|---|
| Semiconductor | ʻAe | ʻAe |
| Hoʻopiʻi | maikaʻi | maikaʻi |
| Voltage | Haʻihaʻi hope | Haʻihaʻi hope |
| ʻōlinolino | ʻOi aku ka maikaʻi o ka luminous | ʻO ka hana haʻahaʻa |
| ʻIke uila | ʻOi aku ka maʻalahi i kēia manawa | ʻAʻole pili i kēia manawa |
| ʻAno hoʻokomo | SMD | Pākuʻi |
ʻO nā pōmaikaʻi o ka hoʻohana ʻana i nā kukui kukui LED
Hoʻohana mau ʻia nā peʻa kukui LED i nā hōʻike LED ma muli o nā pono he nui a lākou e hāʻawi ai. Eia kekahi o nā pōmaikaʻi āu e manaʻo ai.
Micro-Spacing
Hoʻohana nui ʻia nā peʻa kukui LED i nā pale splicing LED micro-spacing, ʻoi aku no nā hōʻike e koi ana i ka ʻōlinolino kiʻekiʻe a me ka hana ʻole. Ua kaulana kēia mau lei no ka micro-spacingnā pale LED i loko.
Kūlike
Hāʻawi nā kukui kukui LED i ka ʻōlinolino like, ke kaulike keʻokeʻo, a me nā pae chromaticity. ʻAʻole like me kekahi mau pale LED e hōʻike ana i nā pae ʻālohilohi like ʻole mai nā kihi like ʻole, ʻo nā mea i hoʻolalelale ʻia e nā kukui kukui e mālama i ka like ʻole o ka hōʻike.
Nānā Angle-Dependant
Ke koho ʻana i nā lei kukui LED, ʻo ke kihi ʻike ka mea nui e noʻonoʻo ai.Hōʻike LED wahopono i kahi kihi ʻike ākea, no laila pono e hāʻawi i nā ʻōlinolino kaulike e hoʻokō i kēia koi.
Nui
Hoʻopili ʻia ka nui o kahi hōʻike LED e ka hoʻohana ʻana i nā pahu kukui. Ua kūpono lākou no nā pale liʻiliʻi, i loko o ka hale, e hoʻolilo iā lākou i mea kūpono no nā hoʻonohonoho e koi ana i nā hōʻike paʻa a maikaʻi.
Kau ola
Hoʻolālā ʻia nā hōʻike LED e hoʻohana ana i nā pahu kukui e lōʻihi ma mua o nā mea me nā ʻano semiconductor ʻē aʻe. Hiki i kēia mau pale ke lōʻihi a hiki i 100,000 mau hola, e hāʻawi ana i ka lōʻihi a me ka ikaika ma muli o kā lākou PCB thermal structure paʻa.
Ka helu hāʻule
ʻOi aku ka haʻahaʻa o ka hāʻule ʻana o nā hōʻike LED me nā lei kukui. Hiki ke hoʻopau i ka hana o ka pale holoʻokoʻa i kahi hemahema i nā kaukani pika (ʻulaʻula, ʻōmaʻomaʻo, ʻulaʻula, akā hoʻemi nui nā pahu kukui i kēia pilikia.
Hiki Anai-Static
Ua ʻike ʻia nā pahu kukui LED no ko lākou mau waiwai anti-static. No ka mea ʻoi aku ka maʻalahi o nā diodes māmā i ka uila paʻa, hiki iā lākou ke hāʻule. Eia nō naʻe, ʻo ke kūʻē ʻana o nā pahu kukui i ka static e hōʻemi ana i ka likelilike o nā hāʻule pili static i ka pale LED.
Pehea e hoʻouka ai i nā kukui kukui LED
Ke kau ʻana i nā lei kukui LED, he mea nui e hahai i nā ʻanuʻu kūpono. Hiki iā ʻoe ke hilinaʻi i nā poʻe loea no ka hoʻonohonoho ʻana, akā inā makemake ʻoe e hana iā ʻoe iho, eia kahi alakaʻi maʻalahi:
- E ʻike i ke ʻano o ke ʻano hana hoʻoheheʻe kukui LED i hoʻohana ʻia.
- E nānā i nā uea ʻehā i hoʻokomo ʻia i loko o ke kukui LED ʻano patch-type.
- E kaha i na kiko nui ma na uwea (maa mau no ka mika) a e oki akahele ma na wahi i kahaia (Eia kekahi, hiki ia oe ke noi i na lei i oki mua ia mai kou mea hoolako mai ma mua o ka lawe ana).
- E nānā i ka pahu hoʻokomo a wehe i ka uhi plastik mai ka pahu.
- E hoʻohui i ke kukui hoʻāʻo, akā e pale i ka uhi ʻana a i ʻole e hoʻopili pololei iā ia i ka uhi.
- E hoʻomaka i ka hoʻokomo pono ʻana ma ka hoʻopaʻa ʻana i ke kumu kukui.
- E kau pono i ke kukui kukui SMD me ka hoʻohana ʻana i ka pahu huelo a me ke kiʻi.
Pehea e koho ai i nā kukui kukui LED pono
ʻO ke koho ʻana i nā lei kukui LED kūpono e pili ana i ka noʻonoʻo ʻana i nā kumu nui e hiki ke hoʻoholo inā ʻoluʻolu ʻoe i kāu hoʻoholo a mihi paha. No ka hōʻoia ʻana e hoʻopau ʻoe i kahi hōʻike LED hana a kiʻekiʻe, eia kekahi mau ʻōlelo aʻoaʻo nui:
- E nānā pono i nā hui solder.
- E koho i kahi puʻupuʻu paʻa e hōʻoiaʻiʻo i kahi pale LED kiʻekiʻe.
- E hōʻoia i ka maʻemaʻe o ka ʻili o nā LED, me ka ʻole o nā stains, a me nā mea haumia ʻē aʻe.
- E nānā i ka maikaʻi o ke kāpili i hoʻohana ʻia i loko o nā pahu kukui ma ke kaomi mālie ʻana iā lākou (hiki i ke kāpili haʻahaʻa ke hana i ka haki ʻana a i ʻole ka deformation).
- He kuleana koʻikoʻi ka ʻenehana Packaging i ka hana ʻana o kāu mau kukui kukui LED a me nā hōʻike a lākou e hana ai.
- E kūʻai wale i nā huahana mai nā mea hoʻolako hilinaʻi a hilinaʻi.
Ka hopena
ʻO ka hoʻomaopopo ʻana i nā pahu kukui LED he mea paʻakikī paha, akā ʻo ka ʻike ʻana i nā ʻāpana o kāu hōʻike LED hiki ke kōkua iā ʻoe e koho i nā pale kiʻekiʻe a hana i ka hapa nui o ko lākou hiki. Hoʻopili ʻia kēia mau pahu i nā LED, akā ʻaʻole lākou nā diodes ponoʻī. ʻO lākou nā semiconductor e mana i ka pale LED holoʻokoʻa a hiki i nā diodes ke hoʻokuʻu i ke kukui.
Inā ʻaʻole maopopo ʻoe e pili ana i ka luʻu hohonu ʻana i nā pahu kukui LED, maikaʻi loa ia. E hōʻoia i ka loaʻa ʻana o ka ʻike maʻamau o lākou, no laila ke koho ʻoe i kāu mau hōʻike LED, hiki iā ʻoe ke kaupaona pono i ko lākou mau pono a me nā hemahema.
