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
Features and Benefits
 The control circuit and the LED share the only power source.
 The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.
 Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of
signal takes place.
 Built-in power-on reset and brown-out reset circuits.
 The gray levels of each pixel are of 256 levels, which achieves “256*256*256=16777216” full-color display, and
the refresh frequency reaches to 2KHz/s.
 Serial cascade interface, data receiving and decoding depend on just one signal line.
 Dual-signal wires version, signal break-point continuous transmission.
 Any two point the distance more than 3m transmission signal without any increase circuit.
 When the refresh rate is 30fps, cascade numbers are far more than 1024 points.
 Data transmitting at speeds of up to 800Kbps.
 Good color consistency reliability, high cost-effective.
Applications
 Guardrail tube series, point light display series, flexible/rigid strips series, module series applications.
 Lighting stage costumes, innovative gadgets or any other electronic products.

Addressable S Shape led strip

Addressable S Shape led strip

    Our dc5v sk6822 60led/m addressable s type led strip is using the sk6822 integrated led as the color lighting source,sk6822 has another advantage:one leds broken down,the signal still transfer will jump the broken IC and continue transfer,so the other ICs still work without any influencing.
 
   Digita RGB S Shape led strip is using flexible copper pcb with good ductility,as well as our creative idea for special shape of pcb. digital rgb S shape led strip not only can 360 degree bend,but also can be 90 degree twist,and it is easy installation,and suitable for the creative Art lighting and advertising word...
here are some pictures about it:

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.

UV LED: UVA 400~315nm,UVB 315~280nm,UVC 280~100nm 


Ultraviolet LED Ultraviolet (UV) LED stands for ultraviolet light emitting diode. A UV LED is an electronic light source with electromagnetic radiation that has a wavelength shorter than that of visible light but longer than x-rays.The UV led has different wavelength which have special function.
we can divide the uv leds into three levels according to their wavelenght:
UVC (200~280nm),is shortwave UV or sterilization UV LED,
UVB (280~315nm),also known as the medium wave UV light,
UVA(315~400nm),Known as long wave violet light or "black light".
And great application in the area of curing,Disinfection,UV Attraction for the flying insects and so on,

The normal application of UV led can be summarized as follows:
 
1. Mosquoto killing 
2. plant growing
3. Counterfeit Detection/Security  
4. Printing 
5. Coating  
6. Crime Inspection

9. Dental Curing 
10. Medical equipment 
11. Cosmetic equipment

SK9822 LED STRIP

SK9822 LED STRIP

     Nowadays,we have newly developed a type of digital led smd,it is sk9822 led,sk9822 is a type of 3 channels integrated digital led with 256 gray scale,and the size of it is 5.0*5.0mm.This type of addressable led has one data cable and one independent clock cable,which has much faster signal and much more stable quality than other ic ,such as sk6812,apa104 ,ws2812b...,
SK9822 LED is upgraded version of APA102 LED,so the sk9822 led tape has the good nature of apa102 led strips,and can use the same code and control system as APA102.

    And we have find a better solution for the outdoor use led strips--half silicone tube led strip,the back of the silicone gel is half silicone and the upper surface is open which can be filled with colloid(silicone gel or epoxy),so the color much more gorgeous and brightness with better lighting color effect,the most importance is sk9822 half silicone tube strip can be outdoor use.

Here are some picture about sk9822 half silicone tube led strip lights:
