Mikanda ya LED imayimira ma diode otulutsa kuwala.
Mfundo yake yowala ndi yakuti PN junction terminal voltage imapanga chotchinga china, pamene mphamvu ya kutsogolo iwonjezeredwa, zotchinga zomwe zingatheke zimatsika, ndipo zonyamula zambiri m'madera a P ndi N zimafalikira wina ndi mzake. Popeza kusuntha kwa ma elekitironi kumakhala kokulirapo kuposa kusuntha kwa dzenje, ma electron ambiri adzafalikira ku P-region, kupanga jekeseni wa onyamula ochepa mu P-region. Ma electron awa amaphatikizana ndi mabowo mu gulu la valence, ndipo mphamvu zomwe zimatuluka zimatulutsidwa ngati mphamvu yowunikira.
Makhalidwe ake ndi awa:
1. Mphamvu yamagetsi: Mikanda ya nyali ya LED imagwiritsa ntchito magetsi otsika kwambiri, magetsi opangira magetsi pakati pa 2-4V. Malingana ndi zinthu zosiyanasiyana, zimayendetsedwa ndi magetsi otetezeka kuposa magetsi apamwamba, makamaka oyenera malo a anthu.
2. Panopa: ntchito yamakono ndi 0-15mA, ndipo kuwala kumakhala kowala ndi kuwonjezeka kwamakono .
3. Kuchita bwino: 80% yocheperako kugwiritsa ntchito mphamvu kuposa nyali za incandescent zokhala ndi kuwala komweko.
4. Kugwiritsa ntchito: Chip chilichonse cha LED ndi 3-5mm lalikulu, kotero chikhoza kukonzedwa m'mawonekedwe osiyanasiyana a zipangizo, ndi zoyenera kusintha malo.
5. Nthawi yoyankhira: Nthawi yoyankha ya nyali yake ya incandescent ndi mlingo wa millisecond, ndipo nyali ya LED ndi nanosecond level.
6. Kuipitsa chilengedwe: Palibe zitsulo zovulaza za mercury.
7. Mtundu: Mtundu ukhoza kusinthidwa ndi zamakono, motsogoleredwa ndi njira yosinthira mankhwala, kusintha mawonekedwe a gulu ndi kusiyana kwa gulu la zinthu, kuti akwaniritse kuwala kofiira, chikasu, chobiriwira, buluu, lalanje. Mwachitsanzo, pamene otsika panopa ndi wofiira LED, ndi kuwonjezeka kwa panopa, akhoza kusintha lalanje, chikasu, ndipo potsiriza wobiriwira.
Ma parameter ake akufotokozedwa motere:
1.Kuwala
Mtengo wa mikanda ya LED umagwirizana ndi kuwala.
Kuwala kowoneka bwino kwa mikanda ndi 60-70 lm. Kuwala kwakukulu kwa nyali ya babu ndi 80-90 lm.
Kuwala kwa 1W kuwala kofiira nthawi zambiri kumakhala 30-40 lm. Kuwala kwa 1W kuwala kobiriwira nthawi zambiri kumakhala 60-80 lm. Kuwala kwa 1W kuwala kwachikasu nthawi zambiri kumakhala 30-50 lm. Kuwala kwa buluu wa 1W nthawi zambiri kumakhala 20-30 lm.
Chidziwitso: Kuwala kwa 1W ndi 60-110LM. Kuwala kwa 3W mpaka 240LM. 5W-300W ndi chip Integrated, ndi mndandanda / kufanana phukusi, makamaka zimadalira kuchuluka kwa magetsi, magetsi.
Lens LED: PMMA, PC, galasi kuwala, silika gel osakaniza (soft silica gel, hard silica gel) ndi zipangizo zina zambiri amagwiritsidwa ntchito ngati mandala oyambirira. Kukula kwa ngodya, kumapangitsanso kuwala kwapamwamba. Ndi lens yaying'ono ya Angle LED, kuwala kuyenera kukhala kutali.
2. Wavelength
Mafunde omwewo ndi mtundu wake umapanga mtengo wokwera.
White kuwala anawagawa ofunda mtundu (mtundu kutentha 2700-4000K), zabwino woyera (mtundu kutentha 5500-6000K) ndi ozizira woyera (mtundu kutentha pamwamba 7000K).
Kuwala kofiyira: gulu 600-680, pomwe 620,630 imagwiritsidwa ntchito makamaka pakuwunikira kwa siteji ndipo 690 ili pafupi ndi infuraredi.
Blu-ray: Band 430-480, yomwe 460,465 imagwiritsidwa ntchito makamaka pakuwunikira magetsi.
Kuwala kobiriwira: Band 500-580, pomwe 525,530 amagwiritsidwa ntchito makamaka pakuwunikira.
3. Ngongole Yowala
Ma LED pazifukwa zosiyanasiyana amatulutsa kuwala kosiyanasiyana. Ngongole yapadera yowala ndiyokwera mtengo kwambiri.
4. Antistatic luso
Mphamvu ya Antistatic ya nyali ya LED imakhala ndi moyo wautali, kotero mtengo wake ndi wapamwamba. Nthawi zambiri kuposa 700V antistatic LED nyali mikanda angagwiritsidwe ntchito kuunikira LED.
5. Kutayikira panopa
Mikanda ya nyali ya LED ndi njira imodzi yowunikira thupi. Ngati pali chosinthira chapano, chimatchedwa kutayikira, mikanda ya nyale ya LED yotayikira imakhala ndi moyo waufupi komanso mtengo wotsika.
Eurbornimapanga Kuwala Panja ku China. Nthawi zonse timasankha mtundu wofananira malinga ndi nyali ndikuyesera zomwe tingathe kuti zinthuzo zikhale zangwiro.
