Application of led Power Amplifier and Signal Amplifier for Low Voltage led Strip lighting
我们常说灯带分2类,第一类控制器方式是直通电流的:
there are two types control method for led strips lighting . The first type of controller is a direct current: 第二类是数字信号,控制器只供信号,补电由变压器单独计算,根据板厚和电压等因素选择不同的位置补偿电压。
The second type is digital signal, the controller only supplies the signal, [...]
Built-in breakpoint resumable transmission
Main features:
1.The control circuit and the RGB chip are integrated in a 5050 packaged component to form a complete external control pixel.
2.The 12V power supply voltage effectively reduces the working current of the entire pixel, and reduces the voltage drop of [...]

Hi everyone ! Here share a Led grid project for a tunnel in Stone mountain City , CA, the USA !
1.It is a 23m length tunnel ,with peremeter length is about 7 meter like the following :
2.The project we use is 161 sqaure [...]
Let’s talk about the difference between SK9822A and apa102 /HD107s/HD108 led.
all of them have Data and Clock signal input and output ,which make their signal more stable ,
and as we know there are extra capacitor on the PCB in some led strip ,
as they need capacitor [...]
APA107-5050 RGB LEDs is the new addressable LED chip on 2018 years, PWM refresh rate can be 9khz, Oscillator frequency can be 30Mhz, can replace APA102 LEDs directly,
and APA102/APA107 use same PCB to produce LED strip. But APA102-5050 RGB LEDs is 20Khz,
so APA107 LEDs [...]

This is Mr Miguel Call eros from MCG who came to visit us and take a 25 hours long trip by plane
Thanks to his professional skill in in Sound& Lighting project and work with us ..
we have cooperated a important 3D dmx led strip [...]
There is some summary after more than 1000 pcs pixel led strip project
第一要点,电和信号分离
firstly , the power wire and signal wire need to be separated! 第二要点:单线接DAT,断点续传BI和 GND 拧一起接GND
secondly, for one dual signl pixel led strip , there is two data wire ,
the second data wire [...]
from Tom’s blog
Two years ago we took a deeper look into the APA102. Although it was more expensive than the common WS2812, and harder to come by, it had some intriguing properties.
The main benefits are a timing-insensitive SPI interface, allowing easy interfacing to standard periphery, [...]
