Ndi kudzipereka kwa China ku United Nations, dziko la China layamba kukonza kamangidwe ka msika wa nyali pang'onopang'ono, kuphatikizapo lamulo lakuti nyali za 100 watts ndi pamwamba sizigulitsidwanso tsiku la dziko chaka chatha. Msika wa babu la LED ukuwoneka kuti wagunda m'manja, malonda akukula pang'onopang'ono, mitundu yosiyanasiyana ya mitengo ya mababu a LED imasiyana kwambiri, ndipo, chifukwa palibe miyezo yoyenera, khalidwe lazinthu ndi zina zimakhala zovuta kwambiri kuti ogula azichita. ndi, sindikudziwa amene nyali LED kukwaniritsa mfundo dziko kupulumutsa mphamvu ndi kuchepetsa umuna, ndipo sindikudziwa ngati mfundo chitetezo.

Malinga ndi kafukufuku wamisika yowunikira akatswiri angapo mumzinda uno, mabizinesi ambiri agulitsa babu la LED ngati chinthu chachikulu. Komabe, mtengo wa babu la LED wamitundu yosiyanasiyana umasiyana kwambiri. Kutengera mwachitsanzo babu 9 watt LED, mtengo wake umasiyana yuan 1 mpaka 20 yuan, komanso mtundu wake ndi wosiyana kwambiri.

Kodi kusiyanitsa ubwino ndi kuipa kwa nyali

Pogula babu la LED, tiyenera kutsatira malingaliro a akatswiri, ndi kulabadira kwambiri ma CD mankhwala, kuyerekezera mtengo ndi zotsatira ziwonetsero. Choyamba, yang'anani ngati pali zizindikiro zilizonse zamalonda ndi ziphaso, monga certification 3C, CE certification, etc., ndikuwona ngati voliyumu yovoteledwa, mtundu wamagetsi, kutentha kwamitundu, kusamala, malangizo achitetezo, malo omwe akugwiritsidwa ntchito amalembedwa bwino. . Komanso, samalani ndi kusintha kwa mtundu wa nyali. Ngati m'kanthawi kochepa, kuwala kwachikasu kumakhala kuwala koyera, kapena kuwala koyera kumakhala kuwala koyera ndi buluu, izi ndizochitika Zotani zomwe ziyenera kusiyidwa. Chifukwa mwina ndi vuto lamagetsi kapena cholakwika chosankha gwero. Kuphatikiza apo, utoto wowala uyenera kukhala wokhazikika, osati wonyezimira, etc.

Kwa ogula, ndikofunika kugwiritsa ntchito mphamvu ndi moyo wonse, ndipo zizindikirozi zikhoza kuyesedwa ndi zida zamakono. Ogula wamba sangathe kuzindikira mtundu wa zinthu pokhapokha powonetsa ogulitsa. Komabe, mutatha kudziwa zambiri zotsimikizira zaukadaulo zomwe zatchulidwa pamwambapa, kuchuluka kwa zomwe mwasankha zomwe mwagula zakhala zikukulimbikitsani, zomwe zimapindulitsa pakugwiritsa ntchito bwino zinthu zopulumutsa mphamvu komanso zoteteza chilengedwe.
