Kū nā pahu LED no nā diodes māmā.
ʻO kāna kumu ʻālohilohi, ʻo ka PN junction terminal voltage e hana i kekahi mea hiki ke hoʻopili ʻia, ke hoʻohui ʻia ka uila bias mua, hāʻule ka pale hiki, a ʻo ka hapa nui o nā mea lawe i nā ʻāpana P a me N e pālahalaha kekahi i kekahi. No ka mea ʻoi aku ka nui o ka neʻe ʻana o ka electron ma mua o ka neʻe ʻana o ka lua, e laha ka nui o nā electron i loko o ka P-region, e hana ana i ka injection o nā mea lawe liʻiliʻi ma ka P-region. Hoʻohui kēia mau electrons me nā puka i loko o ke kaula valence, a hoʻokuʻu ʻia ka ikehu e like me ka ikehu māmā.
Penei kona mau ano.
1. Voltage: Hoʻohana nā kukui kukui LED i ka mana haʻahaʻa haʻahaʻa, ka uila uila uila ma waena o 2-4V. E like me nā huahana like ʻole, ua alakaʻi ʻia e kahi mana palekana ma mua o ka mana uila kiʻekiʻe, kūpono loa no nā wahi lehulehu.
2. I kēia manawa: ʻo 0-15mA ka hana o kēia manawa, a ʻoi aku ka māmā o ka ʻōlinolino me ka piʻi ʻana o kēia manawa.
3. Efficiency: 80% emi ikehu hoʻohana ma mua o incandescent kukui me ka like malamalama pono.
4. Ke hoʻohana ʻia: ʻO kēlā me kēia ʻāpana LED chip he 3-5mm square, no laila hiki ke hoʻomākaukau ʻia i nā ʻano like ʻole o nā mea hana, a kūpono hoʻi no ka hoʻololi ʻana.
5. Manawa pane: ʻO ka manawa pane o kāna kukui incandescent ka pae millisecond, a ʻo ke kukui LED he pae nanosecond.
6. ʻO ka hoʻohaumia ʻana i ke kaiapuni: ʻAʻohe mercury metala ʻino.
7. Ka waihoʻoluʻu: Hiki ke hoʻololi ʻia ke kala e ke ʻano o kēia manawa, alakaʻi ʻia ma o ke ʻano hoʻololi kemika, hoʻoponopono i ke ʻano o ka band a me ka ʻāpana ʻāpana o ka mea, e loaʻa ai ka ʻulaʻula, melemele, ʻōmaʻomaʻo, uliuli, ʻalani ke kukui. ʻO kahi laʻana, inā he ʻulaʻula ke kukui haʻahaʻa, me ka piʻi ʻana o kēia manawa, hiki ke hoʻololi i ka ʻalani, melemele, a me ka ʻōmaʻomaʻo hope.
Ua wehewehe ʻia kona mau palena penei:
1. Ka malamalama
ʻO ke kumukūʻai o nā lei LED e pili ana i ka mālamalama.
ʻO ka'ōlinolino maʻamau o nā peʻa he 60-70 lm. ʻO 80-90 lm ka ʻōlinolino maʻamau o ka ipukukui.
ʻO ka ʻōlinolino o ke kukui ʻulaʻula 1W he 30-40 lm. ʻO ka ʻōlinolino o ke kukui ʻōmaʻomaʻo 1W he 60-80 lm. He 30-50 lm ka olinolino o ke kukui melemele 1W. He 20-30 lm ka olinolino o 1W polū.
'Ōlelo Aʻo: 1W olinolino he 60-110LM. 3W kukui a hiki i 240LM. Hoʻopili ʻia ʻo 5W-300W i ka puʻupuʻu, me ka pūʻolo pūʻulu/parallel, e hilinaʻi nui ʻia i ka nui o kēia manawa, ka uila.
Lens LED: PMMA, PC, aniani aniani, silica gel (silica gel, hard silica gel) a me nā mea ʻē aʻe e hoʻohana mau ʻia no ka lens mua. ʻO ka nui o ke kihi, ʻoi aku ka kiʻekiʻe o ka pono māmā. Me kahi lens LED Angle liʻiliʻi, pono e mamao loa ke kukui.
2. Loʻihi nalu
ʻO ka lōʻihi nalu like a me ke kala ke kumu kūʻai kiʻekiʻe.
Ua māhele ʻia ke kukui keʻokeʻo i loko o ka waihoʻoluʻu mahana (2700-4000K), keʻokeʻo maikaʻi (5500-6000K) a me ke keʻokeʻo anu (ma luna o 7000K).
ʻO ke kukui ʻulaʻula: band 600-680, nona ka 620,630 i hoʻohana nui ʻia no nā kukui kahua a ʻo 690 kokoke i ka infrared.
Blu-ray: Band 430-480, nona ka 460,465 i hoʻohana nui ʻia no nā kukui kahua.
Māmā ʻōmaʻomaʻo: Band 500-580, nona ka 525,530 i hoʻohana nui ʻia no nā kukui kahua.
3. ʻAla ʻālohilohi
ʻO nā alakaʻi no nā kumu like ʻole e hoʻopuka i ka mālamalama ma nā kihi like ʻole. ʻOi aku ka pipiʻi o ka Angle luminous kūikawā.
4. Hiki i ka antistatic
He lōʻihi ke ola o ka hiki antistatic o ke kukui kukui LED, no laila ke kiʻekiʻe ke kumukūʻai. ʻOi aku ka maʻamau ma mua o 700V antistatic LED lamp beads hiki ke hoʻohana ʻia no ke kukui LED.
5. Leakage au
ʻO nā kukui kukui LED he kino kukui conductive hoʻokahi. Inā loaʻa kahi manawa hoʻohuli, ua kapa ʻia ʻo ia ka leakage, leakage o kēia manawa LED kukui beads he pōkole ke ola a me ke kumu kūʻai haʻahaʻa.
ʻEurbornhana i nā kukui waho ma Kina. Ke koho mau nei mākou i ka hōʻailona kūpono e like me nā kukui a hoʻāʻo i kā mākou mea maikaʻi loa e hoʻokō pono i nā huahana.
