Brief description of WS2815 and WS2813
The WS2813 digital led strip is an updated version of the WS2812B, It is DC5V, and with breakpoint continue to function, while one IC is broken, the signal can still pass through.
The WS2815 strip light is DC12v input instead of DC5v input, That is the main difference, and the same is One led broken, other led still work.
Advantage of WS2815 led strip
- WS2815 is a DC12V power supply, one IC with one led, individually addressable control.
- WS2815 had 4 wires: two power wires(12V and GND), two data wires(BI and DI)
- WS2815 is breakpoint continue led strip, one led broken and other still can work
- WS2815 IC: PWM 2KHz/m, Data transmit up to 800kbps, 256 grayscale effect
- We have 30/60/96/144 leds/M, high density led strip
- Also IP20/IP65/IP67/IP68 waterproof we can offer too.
Advantage of WS2813 led strip
(1) One-pixel damage will not affect other LEDs’ work.
(2) Power protection, if + 5V and GND reverse polarity, LED will not burn out.
(3) Dual signal line version, the signal can be jumped.
(4) Original electronic equipment integration will not cause virtual welding during installation.
(1) All electronic components are integrated into the 5050 lamp beads, it does not need any other peripheral auxiliary electronic components to form a complete external control pixel. Also reduce the product installation back soldering, resulting in bad.
2, serial cascade interface, two-wire signal transmission, to achieve the function of HTTP, it will not cause damage to its lower pixels normal lighting under a single pixel, silk who does not affect the overall effect.
3, intelligent reverse polarity protection, product installation access to 5V power supply, in the reverse case, will not cause damage to the lamp beads.
4, built-in signal shaping circuit, any one pixel received signal, through the waveform shaping and then output, to ensure that the line waveform distortion will not accumulate.
6, The transmission distance between any two points is less than 5 meters, without any additional signal amplification circuit.
7, When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points.
8, Data transmission speed up to 800Kbps. consistent light color, high-cost performance.
