How do I choose an LED driver?
Choose a driver with a max wattage higher than the wattage of your light. Do not pair a driver with a light that exceeds the driver’s maximum wattage or with a light that uses less than 50% of the driver’s maximum wattage.
How do LED drivers work?
An LED driver is an electrical device that regulates power to an LED or a string of LEDs. Forward Voltage is the amount of volts the light emitting diode requires to conduct electricity and light up. As temperature increases, the forward voltage of the LED decreases, causing the LED to draw more current.
Why are addressable RGB LED strips so important?
Addressable RGB strips are really cool because they let you control much more than any of the previously mentioned strips. These allow you to individually choose which led is lit, what color it lights up and what brightness it lights up at. Or if it even lights up at all.
How many colors are in a 12V RGB LED?
By mixing those 3 colors you can get any of the 16.7million variations in the RGB spectrum. 12V RGB ones are mostly standard and compatible with all motherboard 12V headers as well as cheap external IR/WIFI controllers. The 5V ones are digital/addressable, which means each LED can shine a separate color at any time.
Why does a RGB LED have 6 legs?
According to the datasheet, it has six legs because it contains 3 LEDs, with nothing common: Many RGB LEDs have a common cathode or common anode, so need only 4 leads. For some applications that may not be acceptable.
How to determine the number of individually addressable LEDs?
This refers to the number of controllable nodes, so if you bought the kind of LED strip that has one controller for every 3 LEDs you’ll need to divide your total number of LEDs by 3. For our WS2812B leds, each led can be controlled individually, so my 57 LEDS needs to be declared as 57 controllable nodes.
