What is SK6812 addressable LED strip light?
SK6812 LED is an intelligent externally controlled LED light source that integrates a control circuit and a light-emitting circuit. It is composed of multiple individually programmable pixels; the pixel contains an intelligent digital interface, a data latch signal shaping，amplifying drive circuit, a power supply voltage regulator circuit, and built-in Constant current circuit, high precision internal oscillator and high voltage programmable constant current control part. The output driver adopts patented PWM technology, which can be matched with Raspberrypi/Arduino UNO development board or dream color LED controller to achieve 256-level grayscale adjustment and mix RGB to produce 16 million colors.
How do addressable LEDs work?
The data transmission adopts the communication mode of unipolar return-to-zero code protocol. After the pixels are powered on and reset, the data is input at the DIN terminal, the first pixel IC stores the extracted data in the internal data latch, the remaining data is amplified by the internal shaping processing circuit and transmitted to the next pixel point, but the 24bit signal is weakened after each pixel point transmission, the number of pixel cascade is only affected by the signal transmission speed, the data transmission speed of SK6812 chip is 800Kbps, there is no flicker phenomenon. The performance of SK6812 driver IC is stable, built-in signal shaping circuit and power-on reset and power-down reset circuits (converting digital signals into analog signals). The IC has high quality, intelligent reverse connection protection, and good LED safety.
What is the feature of SK6812 LED strip?
SK6812 LED strip supports DC5/12/24V low voltage input; DC5V(individually addressable), single LED cuttable, 5m powered at both ends; DC12V, 3 LEDs cuttable, 10m powered at both ends; DC24V, 6 LEDs cuttable, 10m independently powered, The length of the LED strip can be customized. At the same time, we also provide a variety of LED strip light lengths, waterproof grades, different LED densities, and lighting directions to choose from. SK6812 addressable LED strip can produce a single white color (single color/WWA/CCT/RGB/RGBW multiple color temperature options), compatible with 98% of the SPI controllers on the market, suitable for home lighting or industrial lighting.
What is the difference between SK6812 and WS2812B addressable LED strip light?
WS2812B addressable LED strip, by mixing red, green and blue channels in a certain ratio, produces cold white light, overload lighting, not recommended, while SK6812 addressable LED strip can produce separate white light (purer and safer), with a variety of color options for single color/WWA/CCT/RGB/RGBW; SK6812 LED strip supports DC5/ 12/24V low voltage input, a wide range of voltage options, and LED color is less affected by voltage drop than WS2812B; WS2812 only supports DC5V input, long distance lighting, with more obvious voltage drop.
