• Madhiraivha e LED kune AC

Tichifunga, mutyairi we LED uyu anogona kumhanya halogen kana mwenje incandescent ine yakaderera voltage. Asi madhiraivha akajairwa haagone kushandiswa neAC LED madhiraivha nekuti havagone kutaura kana voltage yadzikira. Saka, vane matransformer asina hudiki hudiki.

• Dimmable LED Drivers

Neaya madhiraivha e LED, unogona kudzima mwenje wako we LED. Iyo zvakare inoita kuti iwe udzore kupenya kwe LEDs ine inogara voltage. Uye inoita izvi nekudzikisa huwandu hwazvino hunoenda kune mwenje we LED isati yabatidza.

Zvishandiso zveVatyairi ve LED

• Motokari LED Vatyairi

Nemadhiraivha emhando yepamusoro emotokari dze LED, unogona kutaura mutsauko pakati pemotokari yako mukati nekunze masisitimu emwenje munzira dzakawanda:

1. Boka remwenje
2. infotainment 
3. Kupenya kwemukati nekumashure 

• Backlight LED Vatyairi

LCD backlight LED vatyairi vanowanzo shandisa chaiyo dimming scheme kudzora kupenya kwebacklight.

• Kuvhenekera kwe LED Vatyairi

Iwe unogona kuseta zvishandiso zvako nemadhiraivha eLED kuti ave nemwenje we infrared. Inogonawo kuitwa nerubatsiro rwe-multi-topology inogara-ikozvino controller.

• RGB LED Vatyairi

NeRGB LED madhiraivha, unogona kuwedzera animation kana chiratidzo kune ako ma LED arrays ane anopfuura rumwe ruvara. Zvakare, ivo vanowanzo shanda neakawanda akajairwa interfaces.

• Mutyairi we LED kuratidza

Nerubatsiro rwemadhiraivha ekuratidzira e LED, unogona kudzora kuti ndedzipi tambo dze LED dzinoshandisa mashoma uye akawanda simba. Saka, madhiraivha aya anogona kushandiswa pamwe nehombe nhete pixel kana matrix mhinduro yediki kana mini LED dijitari signage application.

Ndeipi LED Driver yandinoda?

Kuti uone kuti ndeupi saizi ye LED mutyairi inosangana nezvido zvako, unofanirwa kuziva zvinotevera:

1. Iyo voltage yemagetsi mains auchange uchishandisa
2. Huwandu hwesimba hunoshandiswa nema LED ehurongwa
3. Ndeapi rudzi rwemagetsi kana anogara aripo anodiwa nema LED

Kana paine zvimwe zvinhu zvehunyanzvi, sekuda kwekunyatso kudzora ruvara kana mukana wekuratidzwa kwemvura, izvo zvinogona kukanganisa mashandiro anoita madhiraivha e LED. Iyo LED's IP rating inoratidza kuti inodzivirira sei kumvura; mwero wepamusoro unoreva kuti inoshingirira. Iine IP chiyero che44, chigadzirwa chinogona kushandiswa mumakicheni nedzimwe nzvimbo uko mvura inogona kupota ichipfapfaidza pachiri. Mutyairi ane yakakwira IP chiyero, senge 67, inogona kushandiswa kunze. Vatyairi vane IP rating ye20 vanofanira kungoshandiswa mukati, apo pakaoma.

Mamwe mashoko, unogona kuverenga Maitiro Ekusarudza Iyo Yakakodzera LED Power Supply.
