Kodi kalirole kalikonse ndi koyenera ku bafa?

Mfundo zoyendetsera magetsi a LED ndi nyali zopulumutsa mphamvu (CFLs) zimasiyana kwambiri. Ma CFL amatulutsa kuwala powotcha kuti atsegule zokutira za phosphor. Mosiyana ndi izi, nyali ya LED imakhala ndi chipangizo cha electroluminescent semiconductor chip, chomwe chimayikidwa ku bulaketi pogwiritsa ntchito zomatira zasiliva kapena zoyera. Chipcho chimalumikizidwa ndi bolodi la dera kudzera pa mawaya a siliva kapena golide, ndipo msonkhano wonse umasindikizidwa ndi epoxy resin kuteteza mawaya amkati, asanatsekedwe mu chipolopolo chakunja. Kumanga uku kumaperekaMagetsi a LEDkukana kwambiri mantha.

Pankhani ya mphamvu zamagetsi

Poyerekeza ziwirizo pakuwala kofanana (ie, kuwala kofanana),Magetsi a LEDamangodya 1/4 yokha ya mphamvu zomwe zimagwiritsidwa ntchito ndi CFL. Izi zikutanthauza kuti kuti mukwaniritse kuyatsa komweko, CFL yofuna mawati 100 amagetsi ingasinthidwe ndi nyali ya LED pogwiritsa ntchito ma watts 25 okha. Mosiyana ndi zimenezi, pogwiritsa ntchito mphamvu zomwezo, nyali za LED zimapanga 4 kuwirikiza kowala kwa CFLs, kupanga malo owala komanso owoneka bwino. Izi zimawapangitsa kukhala oyenera makamaka pazochitika zomwe zimafuna kuunikira kwapamwamba-monga kutsogolo kwa magalasi osambira, kumene kuwala kokwanira kumatsimikizira kudzikongoletsa bwino ndi zodzoladzola.

Pankhani ya moyo

Kusiyana kwa moyo wautali pakati pa magetsi a LED ndi CFL ndikodabwitsa kwambiri. Magetsi apamwamba kwambiri a LED amakhala ndi maola 50,000 mpaka 100,000, pomwe ma CFL amakhala ndi moyo pafupifupi maola 5,000 okha—kupanga ma LED kuwirikiza 10 mpaka 20 kukhalitsa. Kutengera maola 5 akugwiritsa ntchito tsiku lililonse, nyali ya LED imatha kugwira ntchito mokhazikika kwa zaka 27 mpaka 55, pomwe ma CFL amafunikira kusinthidwa ka 1 mpaka 2 pachaka. Kugwiritsa ntchito mphamvu pang'ono kumatanthawuza kuchepetsa kwambiri mtengo wamagetsi wanthawi yayitali, ndipo kutalika kwa moyo kumachotsa zovuta komanso ndalama zosinthira pafupipafupi.

Kumbali ya ntchito zachilengedwe

Magetsi a LED amakhala ndi mwayi wowoneka bwino kuposa ma CFL, ndipo izi zimawonekera kwambiriMagalasi osambira a LED. Kuchokera pazigawo zapakati mpaka kuzinthu zakunja, amatsatira mosamalitsa miyezo ya chitetezo ndi chilengedwe: tchipisi tawo tamkati ta semiconductor, epoxy resin encapsulation, ndi matupi a nyale (opangidwa ndi zitsulo kapena mapulasitiki ochezeka ndi zachilengedwe) alibe zinthu zapoizoni monga mercury, lead, kapena cadmium, zomwe zimachotsa zoopsa za kuipitsa. Ngakhale akafika kumapeto kwa moyo wawo wautumiki, zida zowonongeka zaMagalasi osambira a LEDitha kukonzedwa kudzera munjira zobwezerezedwanso nthawi zonse popanda kuwononganso nthaka, madzi, kapena mpweya—ndikuchita bwino kwambiri pa moyo wawo wonse.Mosiyana ndi izi, ma CFL, makamaka akale akale, ali ndi zovuta zachilengedwe. Ma CFL achikhalidwe amadalira mpweya wa mercury mkati mwa chubu kuti atsegule phosphor kuti atulutse kuwala; CFL imodzi imakhala ndi 5-10 mg ya mercury, pamodzi ndi zotsalira zazitsulo zolemera monga lead. Ngati zinthu zapoizonizi ziwukhira chifukwa chakusweka kapena kutayidwa kosayenera, mercury imatha kusungunuka mwachangu mumlengalenga kapena kulowa munthaka ndi madzi, kuwononga kwambiri manjenje ndi kupuma kwamunthu, ndikusokoneza chilengedwe. Ziwerengero zikuwonetsa kuti zinyalala za CFL zakhala gwero lachiwiri lalikulu la kuwonongeka kwa mercury mu zinyalala zapakhomo (pambuyo pa mabatire), ndi kuipitsidwa kwa mercury kuchokera kutayidwa kosayenera kumabweretsa zovuta zazikulu pakuwongolera zachilengedwe chaka chilichonse.

Kwa zipinda zosambira - malo ogwirizana kwambiri ndi thanzi la banja - ubwino wa chilengedweMagalasi osambira a LEDndi zatanthauzo kwambiri. Iwo samapewa kokha kuopsa kwa chitetezo cha mercury leage kuchokera ku CFLs yosweka komanso, pogwiritsa ntchito zinthu zopanda poizoni, amapanga chotchinga chosaoneka cha thanzi la zochitika za tsiku ndi tsiku monga kutsuka ndi skincare, kuonetsetsa mtendere wamaganizo ndi eco-ubwenzi ndi ntchito iliyonse.
