General Description
WS2815-MINI is an intelligent control LED light source that the control circuit and RGB chip are integrated in a
package of 3535 components,outlook is the same as 5050 LED;Any components is a pixel;Its internal includes
intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal
oscillator and a programmable constant current control part,which achieves highly consistent color effect.Realize double
signal transmission,if any pixel failure,it won’t affect the whole display;
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port
receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data
which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port.
After transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology,
making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal
transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if
DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's
damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after
power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
300us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and

inexpensive MCU.

WS2813 LED

WS2813 Signal Break-point Continuous Transmission LED

Refer to WS2813 LED, everyone may think of the ws2812b led,though they are all 3ch integrated digital rgb led (built-in ic led),but they have much different,firstly,ws2813 is dual-signal wire version in ws series leds,secondly the ws2813 have one more function:signal continuous transfer when there some break led,which can greatly improve the stability of the digital leds;the third one is tha the capacitance and resistance also package inside the led,this also will be much convenience for the pcb component designer,and reduce some SMT ,and save many space for other element.




General description
WS2813 LED is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package
of 5050 components. Its internal include intelligent digital port data latch and signal reshaping amplification drive circuit.
Also include a precision internal oscillator and a 12V voltage programmable constant current control part,
which achieves highly consistent color effect.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive
data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which
reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After
transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology, making
the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN
do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage
does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
250us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and
inexpensive MCU.
There’re in a choice of 18mA or 5mA current version, and also in a choice of high brightness or cost-effective version.
That is to say, WS2813 is provided with four versions

2835 constant current led strip

2835 constant current led strip

     Constant current led strip has its great advantage,for it is using the constant current IC(constant current transistor) in each group,so the current of the strip is almost the same,also the voltage of each group is the amost the same as the power supply without little voltage drop.
Each pcs of dc24v 2835 60led/m cc led strip can be as long as 25m with totally the same color,even as long as 50m when adding extra power on both side of the strips.
Our 2835 constant current led strip is dc24v safe low voltage with the long distance connection and 50000h lightspan,can be use to replace the high voltage led strip lights(high voltage is not so safe and just can be use in one year).
It is good choice for the led lighting projects with less power wire and easy installation.
