Malangizo Ogulira Magetsi a Kuphulika kwa LED

Msikawu wadzaza ndi mitundu yosiyanasiyana ya magetsi osaphulika a LED, iliyonse ili ndi mawonekedwe osiyanasiyana kuchokera kwa opanga osiyanasiyana. Choncho, munthu amasankha bwanji pagulu lalikululi lazinthu? Chifukwa pali zizindikiro zina zowunikira momwe zowunikira za LED zimayendera, nali chitsogozo chapadera chothandizira pakugula zinthu ndikuthandizira kupewa kutayika pamapulojekiti owunikira chifukwa chakusaka kosayenera.

1. Mtundu Wopereka Mlozera (CRI):

Musanagule, ndikofunikira kuyang'ana zomwe zagulitsidwa kapena kufunsa wogulitsa za CRI. Nthawi zambiri, Magetsi a LED okhala ndi CRI pakati pa RA80 ndi 100 kuwonetsa magwiridwe antchito abwino kwambiri; omwe ali pakati pa RA50 ndi 79 kukhala ndi mtundu wa ntchito, pomwe magetsi okhala ndi CRI pansi pa Ra50 ali ndi mtundu wosawoneka bwino. Choncho, Ndikoyenera kusankha zowunikira za LED zokhala ndi CRI yayikulu.

2. Pewani Kuwala:

Kuwala kumakhudza kwambiri mtundu wa kuyatsa ndipo kuyenera kuchepetsedwa. Sankhani magetsi omwe samatulutsa kuwala. Moyenera, sankhani zosintha zokhala ndi ma frosted diffusers omwe amatulutsa zofewa, ngakhale kuwala.

3. Kuthekera Kwapang'onopang'ono kwa Zowunikira Zowunikira za LED:

The “luso lowala” Kuwala kwa LED komalizidwa ndiko kutulutsa kokwanira kowala kotulutsa ndi LED pansi pa voliyumu yovotera yogawidwa ndi mphamvu zonse zomwe zimagwiritsidwa ntchito, kuyeza mu lumens pa watt (lm/W). Kukwera mtengo uku, bwino mphamvu yopulumutsa mphamvu, ndi magetsi ochepa omwe amagwiritsidwa ntchito. Choncho, sankhani zowunikira za LED zokhala ndi ma lumens apamwamba pa watt (makamaka wamkulu kuposa 80 lm/W; Mwachitsanzo, zokonza zokhala ndi mphamvu ya ≥85 lm/W ndi chisankho chabwino).

4. Kutentha kwa LED Kukwera:

Nthawi zambiri, zololedwa kutentha kukwera kwa magetsi a LED omwe akugwiritsidwa ntchito kuli pakati pa 25 ℃ mpaka 30 ℃. Mwachindunji, Kutentha kwa heatsink ya LED ndi kutentha komwe kumakhala komanso kukwera kovomerezeka. Izo zikutanthauza, ngati kutentha kozungulira ndi 37 ℃, kutentha pa heatsink ya LED kuyenera kukhala 67 ℃ (37℃+30 ℃). Ngati ipitilira izi, kukwera kwa kutentha kumaonedwa kuti sikunagwirizane. Kutentha ndiye mdani wa magwiridwe antchito a LED; kutentha kochepa kumapangidwa, kumapangitsanso kuwala kwa kuwala kwa LED. Kuphatikiza apo, kukwera kofulumira kwa kutentha pa heatsink kumawonetsa kukhathamiritsa kwamafuta kwambiri komanso kutsika kwamafuta kwamagetsi owunikira a LED..

5. LED Lifespan:

Kuwala koyambirira kwa kuwala kwatsopano ndi 100%. Popita nthawi, mphamvu yowala ya kuwala idzachepa. Kutalika kwa moyo wa LED ndi nthawi yomwe imatenga kuti kuwala kwake kuchepe 70% za kusintha koyamba. Mwachibadwa, nthawi yayitali bwino. Mwachitsanzo, Ma LED ochokera kuzinthu zodziwika bwino amatha kukhalitsa 30,000 maola, zomwe zimakhala zosavuta makamaka pama projekiti akuluakulu owunikira.

Awa ndi malangizo oti musankhe magetsi osaphulika a LED. Mwachiyembekezo, bukhuli lidzakuthandizani kupanga zisankho mwanzeru.
