LED masanjidwewo: kufotokoza, ntchito

LED masanjidwewo akuimira LEDs munthu aliyense payekha kapena msonkhano LED, anapanga pa gulu timibulu. mawerengetsedwe oterowo aona ndithu ankagwiritsa ntchito mu machitidwe onse kuunikira ndi malo, misewu ndi nyumba pamakoma, ndi kuwagwiritsa ntchito kuti m'nyumba kuyatsa munthu Mwachitsanzo, mu spotlights. LED masanjidwewo akhonza kumupatsa, malingana ndi cholinga, monga mbali kuwala kamwazi, ndi zomwe zinachititsa.

Kufunika kuphunzira ndondomeko ya kulumikiza LED mkulu mphamvu nyumba, komanso kugwirizana ndi ndondomeko kapangidwe ndi luso mavuto panopa chifukwa cha kutchuka kukula mofulumira wa mankhwala, ndipo, ndithudi, chikoka cha kukuchititsa zimenezi makampani kuyatsa. Chifukwa chotero amadza chachikulu ndi chiwerengero cha madalitso amene akhala akwaniritsa chifukwa cha m'malo a fulorosenti, zingalowe, gasi kumaliseche gwero la insolation kuwala zipangizo zamakono michenga yopangira zida zamagetsi. Kale kuti palibe chinsinsi chimene ntchito diodes wapamwamba-mphamvu akhoza zayamba kuchepetsa mphamvu ankadya, komanso kuwonjezera mlingo wa kudalirika kwake ndi zachilengedwe ochezeka magwero kuwala.

Chifukwa ubwino pamwamba, chitukuko ndi kupanga njira zamakono atsopano m'munda zida LED lero ikuchitika mofulumira. Ziyeneretso za khalidwe la kupezeka kwa panamveka wowala kamwazi, wowala mphamvu michenga yopangira zida zamagetsi LEDs mowirikiza kuwonjezeka, ndipo izi zikutanthauza kuti zofuna chinawonjezeka ndi mawerengetsedwe.

LED masanjidwewo akuimira gulu timibulu m'gulu mfundo wosanganiza - mndandanda-yomweyi. Mtengo wa voteji ndi ziliri pa matrixes ndi LED pang'ono kuposa voteji ndi panopa pa LEDs wamba. Ichi ndi chifukwa chakuti zikuchokera masanjidwewo kumaphatikizapo gulu la zinthu michenga yopangira zida zamagetsi. Kuti ogwira ntchito nthawi yaitali zosiyanasiyana LED ayenera akhale okonzeka ndi wamphamvu ndi wolimba DC mphamvu zoyendetsera (kapena mphamvu gwero ndi dalaivala), ndi koziziritsira. Nthawi zambiri mu ntchito ya koziziritsira ntchito zotayidwa kapena heatsink mkuwa.

Khalani limasonyeza kuti tsiku wonse ndi wotchuka kwambiri mkulu-mphamvu LED zosiyanasiyana. Ndipotu, mankhwala amaloledwa zayamba kuchepetsa ndalama mkulu-mphamvu nyale kapangidwe ndi kaphatikizidwe tchipisi angapo chimodzi. kucheza walola opanga osati kuchepetsa ndalama yopanga mindandanda yamasewera kuunikira, koma ndithu kusintha khalidwe lawo. Ichi ndi chifukwa LED masanjidwewo dera ali kwambiri yafupika, ndi circuitry chosavuta, choncho ndi otetezeka.

An chizindikiro chofunika cha khamu aliyense LED ndi dzuwa wowala. Izo zimatengera mtundu wa makhiristo kuwala. Komabe, ayenera kumvetsa kuti ngakhale ndi ntchito timibulu mkulu kalasi, linanena bungwe kuwala kwa masanjidwewo adzakhala penapake poyerekeza zokolola akukhudzidwira ndi timibulu m'gulu kamangidwe. Ichi ndi chifukwa zotsatira za kukhotera (mwagwirizana mayamwidwe) wa kuwala, diodes anakonza pafupi yomweyo.
