The 505OLED built-in driver full-color lamp bead is simply a lamp bead, but it has a built-in driver IC, which is a very smart lamp bead! Expansion Optoelectronics does this, and the SK6812 they developed is a integrated control circuit. The intelligent external control LED light source integrated with the light-emitting circuit. Its appearance is the same as a 505OLED lamp bead, and each element is a pixel.
The pixel contains an intelligent digital interface data latch signal shaping and amplifying drive circuit. It also contains a high-precision internal oscillator and a 5V high-voltage programmable constant current control part, which effectively ensures the color of the pixel point light is highly consistent. The data protocol adopts a single-wire return-to-zero code communication method. After the pixel is power-on reset, the DIN terminal accepts the data transmitted from the controller. The first 24bit data sent is extracted by the first pixel and sent to the inside of the pixel. After the remaining data is reshaped and amplified by the internal shaping processing circuit, the remaining data is forwarded and output to the next cascaded pixel through the D0 port. After each pixel is transmitted, the signal is reduced by 24bit.
Pixels adopt automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, only limited by signal transmission speed requirements. LED has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra-low power, and ultra-long life. Integrating the control circuit on the LED makes the circuit simpler, smaller in size, and easier to install.
505OLED built-in driver full-color lamp beads characteristics
1. Less power consumption: LEDs with a luminous efficiency of 75Im/w reduce power consumption by 80% compared to incandescent lamps with the same brightness; 2. Long life: product life is up to 50,000 hours, 24 hours of continuous lighting can be used for 7 years
3. Nanosecond response speed makes dynamic control of brightness and color easy: dynamic color change and digital control can be realized
4. Large design space: it can realize the organic integration with the building, and achieve the effect of seeing only the light but not the light. 5. Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.
6. Color: Different wavelengths produce different colored lights, bright and saturated, no filter is needed, and can be controlled by the three primary colors of red, green and blue to form a variety of different colors, which can achieve various color changes such as full-color gradients
