Mis on LED-valgusriba kontroller?
LED-riba kontroller 1, simulatsioon
LED lights come in two basic types: analog and digital. They have different controls, so it's good to know which one you need for your project. Analog bars are available in monochrome (one color) or RGB (full spectrum). They are sold in scrolls and can be cut into small pieces. These segments are marked with metal contact pads, sometimes with scissor icon screens printed on them (love those!). . The strips shown here are 5cm and 10cm long and each segment contains 3 LEDs. Typically, the light bar uses 30, 32, 60 or 120 LEDs per meter, which changes the price and power consumption.
LED-riba kontroller 2, käitumine
Disappear together and stay together with the flashing LED. All LEDs on the light bar will act as one LED, and they are not addressable. One way to see it is that they don't have any drive chips visible on the strip (that's digital!). . The digital strip comes with RGB LEDs, and the strip has a driver chip to control the LEDs separately. These are also referred to as separately addressable or addressable only. The zone where the LPD8806 driver is used is shown here. Other popular drives you will see also use WS2801 drives, while using WS2812 RGB LED light strips, these drives are installed directly in the LED package! They can also be segmented and cut into bite-size pieces.
LED-riba kontroller 3, toiteplokk
Selleks, et teie LED-lambiriba element sobiva võimsusega helendaks, peate teadma elemendi tarbitavat voolu ja selle tööpinget. Kui olete need kaks asja teadnud, saate valida toiteallika. Pidage meeles, et praegune loterii võib olla keeruline äri. Siin võtame teabe andmetabelist ja sisestame selle mõnesse lihtsasse võrrandisse, et saada maksimaalne nõutav vool, sest andmetabelis on teave selle kohta, kas LED põleb täis heledusega.
