Icho chinhu chinowanzoitika kuti mwenje we LED unosviba uye kusviba sezvaanoshandiswa.Pfupisa zvikonzero zvinogona kusvibaChiedza che LED, izvo zvisiri chimwe chinhu kunze kwezvitatu zvinotevera.

1.Drive kukuvara

Mwenje wemwenje we LED unodiwa kuti ushande pa low DC voltage (pazasi 20V), asi yedu yakajairika mains simba ndeye AC yakakwira voltage (AC 220V).Kushandura simba remagetsi musimba rinodiwa nemarambi emarambi, tinoda mudziyo unonzi "LED inogara iripo yekutyaira magetsi".

Nechepfungwa, sekureba ma paramita emutyairi achienderana nerambi bead ndiro, inogona kuramba ichigoneswa uye kushandiswa zvakajairwa.Mukati memutyairi wakaoma.Kutadza kwechero mudziyo (senge capacitor, rectifier, etc.) kunogona kukonzera shanduko yevoltage inobuda, uye zvoita kuti mwenje udzime.

Kukuvadzwa kwemutyairi ndiyo inonyanya kukanganisa marambi e LED.Kazhinji inogona kugadziriswa mushure mekutsiva mutyairi.

2.Led yakatsva

Iyo LED pachayo inoumbwa nemarambi mabheji rimwe nerimwe.Kana imwe kana chikamu chazvo chisina kubatidzwa, chinosungirwa kudzima mwenje wose.Marambi emarambi anowanzo kubatanidzwa munhevedzano uyezve achienderana - saka kana bhero remwenje rikapiswa, bhechi remarambi rinogona kusavheneka.

Pane mavara matema ari pachena pamusoro pebhedhi remwenje rakatsva.Zviwane, zvibatanidze kumusana netambo uye pfupi pfupi;Kana kuti bhanga remwenje idzva rinogona kugadzirisa dambudziko.

Led dzimwe nguva yaipisa imwe, zvinogona kuitika netsaona.Kana iwe uchipisa kazhinji, iwe unofanirwa kufunga nezve dambudziko redhiraivha - kumwe kuratidzwa kwekutadza kwekutyaira kuri kupisa mabheji emwenje.

3. LED chiedza attenuation

Izvo zvinonzi kuora kwechiedza ndechokuti kupenya kwechiedza kunowedzera kuderera uye kuderera - izvo zvinonyanya kuoneka mumarambi e-incandescent uye fluorescent.

Mwenje we LED haugone kudzivirira kuora kwechiedza, asi kukurumidza kwayo kuora kwechiedza kunonoka, uye kazhinji zvakaoma kuona shanduko neziso rakashama.Nekudaro, hazviregi kuti yakaderera-yemhando led, kana yakaderera-yemhando yemwenje bhedhi ndiro, kana nekuda kwechinangwa zvinhu zvakadai sekushayikwa kwekupisa kupisa, iyo LED mwenje yekuora kumhanya inova nekukurumidza.
