Iyini i-WS2811?

I-ws2811 iyi-rgb led light control chip engaguqula idatha ibe amasiginali okulawula ngokusebenzisa amasiginali we-io ukuze kuzuzwe izilungiselelo zombala ezahlukahlukene.

I-ws2811 iyisekhethi ezinikele yokulawula idrayivu ye-LED eneziteshi ezintathu. I-chip iqukethe i-digital interface ehlakaniphile yedatha ye-latch yesignali ye-latch yomjikelezo wedrayivu yokukhulisa amandla, i-oscillator yangaphakathi enembayo ephezulu kanye nomshayeli ophumayo wamanje ozinzile ongu-12V. Amashaneli amathathu anomsebenzi othize wokulibaziseka wokuvula, onganciphisa ukugeleza kwesekethe.

I-chip isebenzisa indlela yokuxhumana yekhodi ye-single-wire-to-zero. Ngemuva kokuthi i-chip isethwe kabusha ku-inthanethi, itheminali ye-DIN ithola idatha kusilawuli. Idatha yokuqala ye-24-bit ethunyelwe ikhishwa yi-chip bese ithunyelwa ku-latch yedatha ngaphakathi kwe-chip. Esele Ngemva kokuba idatha ikhuliswe ukucutshungulwa kokubunjwa kwangaphakathi, idluliselwa futhi ikhishwe ku-chip yezinga elilandelayo ngembobo ye-DO, ukuze kuzuzwe ukudluliswa kwedatha ngesivinini esiphezulu.

I-latch yedatha ngaphakathi kwe-chip ikhiqiza amasiginali okulawula umjikelezo wemisebenzi ahlukene kumatheminali okulawula i-OUTR, OUTG, kanye ne-OUTB ngokusekelwe kudatha etholiwe ye-24-bit. Uma ulinde ukuthi isignali ye-RESET ifakwe kutheminali ye-DIN, wonke ama-chips athumela ngokuhambisanayo idatha etholiwe engxenyeni ngayinye, i-chip izophinde yamukele idatha ngemva kokuphela kwesignali. Ngemva kokuthola idatha yokuqala ye-24-bit, idlulisela imbobo yedatha ngembobo ye-DO. Ngaphambi kokuthi i-chip ithole ikhodi ye-RESET, okukhiphayo kwasekuqaleni kwezikhonkwane ze-OUTR, OUTG, ne-OUTB kuhlala kungashintshile. Ngemva kokuthola ikhodi yeleveli ephansi ye-RESET engaphezu kuka-280μs, i-chip izokhipha ububanzi be-pulse yedatha engu-24bit PWM esanda kutholwa ku-OUTR, OUTG, kanye nezikhonkwane ze-OUTB.

Amanothi ku-ws2811:

Izidingo zokukhanya zama-LED ziyahlukahluka kuye ngezikhathi nemikhiqizo ehlukene. Isibonelo, uma izibani zekhawunta zobucwebe be-LED zibekwe kwezinye izitolo ezinkulu, sidinga ukukhanya okuphezulu ukuze sikhange. Ngomsebenzi ofanayo wokuhlobisa, kunemikhiqizo ehlukene efana nezibani ze-LED nemichilo yokukhanya enemibala ye-LED.

Ikhono le-Antistatic: Ikhono le-Antistatic Ama-LED anamandla aqinile e-antistatic anempilo ende, kodwa intengo izoba phezulu. Ngokuvamile i-antistatic ihamba phambili ngaphezu kuka-700V.

Izici zomkhiqizo we-ws2811:

1.Isebenzisa amandla kagesi we-DC12V we-low-voltage ukuze ishayele kanye nokunikezwa kwamandla, okwenza kuphephe ukuthi abasebenzisi basebenzise.

I-2.Sebenzisa i-FPC eguquguqukayo njengento eyisisekelo yomugqa wokukhanya, onezici ze-conductivity kagesi enhle, ukuchithwa kokushisa okusheshayo, nokumelana nokugoba. Ingagotshwa ibe yizimo ezihlukahlukene ngokuthanda kwakhe.

3.Isebenzisa ubuhlalu besibani be-SMD?020RGB kanye ne-chip yangaphandle ye-WS2811 IC, okuyenza ibe umucu wokukhanya ohlelekayo.

I-4.Ingenziwa ibe yimiphumela ehlukahlukene engangeni manzi efana ne-glue evuzayo yokuvimbela amanzi, i-casing waterproofing, i-glue injection yokuvimbela amanzi ku-casing, njll okwenza isetshenziswe ezindaweni eziningi.

I-5.Imiphumela ehlukahlukene yokukhanyisa ingafinyelelwa ngohlelo lwesilawuli futhi ingasetshenziswa ezigcawini ezahlukene.

I-6.ws2811 iwumugqa wokukhanya wokulawula okukodwa okunombala wokukhanya ongaguquki. Kuwumugqa wokukhanya ongabizi kakhulu.

Izindawo zesicelo ze-ws2811:

1.Izintambo zokukhanya zohlamvu olukhanyayo ezinombala ogcwele we-LED, amamojula e-LED anombala ogcwele, imichilo yokukhanya okuthambile enombala ogcwele we-LED nemichilo yokukhanya okuqinile, namashubhu e-LED egada.

Imithombo yokukhanya yephoyinti le-2.LED, izikrini ze-pixel ze-LED, izikrini ezimise okukhethekile ze-LED, imikhiqizo ehlukahlukene ye-elekthronikhi, namatende ezinto zikagesi.
