Pali njira ziwiri zazikulu zoyatsira nyali za LED.

Pali njira ziwiri zazikulu zoyatsira nyali za LED. Pamsika wamakono wapakhomo, pali njira ziwiri zopangira magetsi a nyali za LED: mawaya amtundu umodzi ndi maulendo awiri. Kupyolera mu kusanthula kwathunthu kwa matebulo awiri omwe ali pamwambawa, titha kuona kuti Philips pogwiritsa ntchito mawaya amtundu umodzi ndi otetezeka. Zogulitsa zamtundu ndizotetezeka, koma IEC salola kugwiritsa ntchito masiwichi, omwe sakwaniritsa zofunikira.

Komabe, kukhudzana kwamakono kwazinthu zina zitatu zomwe zimagwiritsa ntchito mawaya awiri-ziwiri ndizoposa 0.5 mA, ndipo pali chiopsezo cha kugwedezeka kwamagetsi panthawi yoika. Malinga ndi muyezo wa International Electrotechnical Commission (IEC), mawaya okhala ndi mbali imodzi ndi otetezeka kusiyana ndi mawaya awiri. Komabe, chifukwa cha mtengo wotsika wa machubu a kuwala kwapawiri-terminal mawaya a LED, komanso kusowa kwa chidziwitso chokhudza kuopsa kwa chitetezo chawo, ogula nthawi zambiri amasankha machubu owunikira a LED molakwika pogula zinthu.

Kuphatikiza apo, mawaya okhala ndi mbali imodzi ndi mawaya awiri amafunikira kulumikizidwanso pakukhazikitsa, koma anthu ambiri amangoganiza mozama kuti kuyimbanso mawaya amtundu umodzi ndikovuta kwambiri. Pazifukwa izi, nyali za LED zowirikiza kawiri ndizodziwika ku China, zomwe zimabweretsa ngozi zazikulu zachitetezo kwa ogula. M'mayeso omwe ali pamwambapa, ngakhale zinthu zamtundu wa Philips ndi A ndizabwino kwambiri pankhani yachitetezo, koma zopangidwa zamtundu wa A zimagwiritsa ntchito njira yosinthira yawiri-terminal wiring ndi switch yowonjezera. Kuphatikiza pakuwonjezera kuvutikira kwa kuyimbanso, sikukwaniritsa miyezo yachitetezo ya IEC. , zomwe zingayambitse zovuta zambiri kugwiritsa ntchito.

Ngati wogwiritsa ntchito magetsi aiwala kuyatsa chosinthira pa chubu cha nyali pomwe nyali yayikidwa, chosinthira khoma pansipa sichingayankhe chilichonse. Zitha kuwoneka kuchokera ku izi kuti chubu la nyali la Philips LED T8 lili ndi maubwino ambiri pakuyika kosavuta ndi chitetezo, limagwirizana ndi miyezo yoyenera ya IEC, ndipo limapereka chitsimikizo chofunikira pachitetezo cha moyo wa ogula ndi katundu.
