Shenzhen Shengwei's WS2812 family is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. effectively ensuring the pixel point light color height consistent.
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. pixel adopt auto resha-ping transmit technology, making the pixel cascade number is not limited the signal transmission, only depend on the speed of signal transmission.
    LED with low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED   above becoming more simple circuit, small volume, convenient installation.
Product upgrading
  WS2812B is the development and new generation of product based on WS2812. It not only inherited all the good qualities of WS2812 but also improved the IC from mechanical arrangement outside to the structure inside, further enhance the stability and efficiency. Compared to the ws2812 ws2812b, we add a reverse protection circuit. It will ensure you to reverse connection of power supply without any damage to the product, to increase the stability of the product which in effect.
                                                   
WS2812 Adanced Type   
WS2812B and WS2812 consistent in size, but the PAD number of the former are reduced to 4 Pin, with the decrease of the spacing between adjacent legs increases greatly, reduces circuit applications due to some causes problems such as short circuit. an the chip power supply PIN( VDD) and VSS are arranged diagonally, when in PCB layout area of copper foil bearing power, the power and ground can be very wide, power capacity is stronger, the higher the stability.
The brightness is higher
An extrude advantage of is that the RGB chip on WS2812B has a higher brightness and color uniformity than WS2812.
Internal structure improved
  WS2812B has a better structure than WS2812, after we modified the structure, the control circuit and the RGB light have been separated, it has a better heat dissipation performance. The two modules work independently, one does not relate to the other, line distance is shorter and makes the work more stable than that of before. 

Product Feature

• The control principle, an IC control three LED to form a loop (group a), the controller through the inside of the control IC for FPCB to control circuit, so as to control LED lights change different effects; Such as flashing, chase and jump, monkey clockwise and anticlockwise monkey, monochromatic monkey, monkey discoloration, single chase from beginning to end, flowing water, simulation of lightning, etc.; This article lamp change effect is not limited to the current controller built-in 94 kinds of effect, can according to customer needs, to write; Line screen can display, in the form of words, letters, pictures, animations, and so on.
• Environmental protection, safety, high quality highlight SMD LED 5050. The advantages of small power consumption, low heat, no glare, impact resistance, etc. Low voltage dc 5 v power supply, high safety and reliability.
• Color is rich and varied according to customers need to be adjusted by the controller.
• Long service life, the life expectancy of 50000 hours.
• Cutting, welding and convenient freedom: each group of LED can form a loop, can be arbitrary along the tangent truncation and welding meet customer requirements of various light length requirements.
• Soft: use soft FPCB board as the substrate, optional docking, bending, cutting and arbitrary fixed on the concave and convex surface.
• Light, thin, fit in narrow space installation.

Specification

● Protection class: non-waterproof

5V WS2812 Family: 5VDC 30pix/m, 5VDC 60pix/m, 5VDC 96pix/m, 5VDC 144pix/m.





Application

• Support in the underwater lighting engineering
  Canopy, and the edge of the bridge arch/park/theatre/aircraft cockpit lighting
  
  Strip Instruction
  
  

• Indoor installation: LED lights for indoor installation is simple, because do not have to withstand the wind and rain. Installation can go directly to tear light bar on the back of 3 m double-sided adhesive on the surface of the sticker, then a fixed in the place where you need to install the lamp according to the flat. If there are any corner or article lamp is too long too short, LED lights can be brought in each group with scissors logo tangent place any cutting or welding used alone.
• Outdoor installation: outdoor installation due to withstand the wind rain, can't use 3 m glue fixed, therefore often adopt the way of card slot fixed outdoor installation, need to cut and connection, methods as well as indoor installation, just need additionally equipped with waterproof glue, in order to consolidate the join waterproof effect.
• Power supply connection methods: general voltage for the dc DC5V LED magic lantern belt, so you need to use the switch power supply, power supply according to the size of the LED lights with the power and the connection of length.
• Controller connection mode: the LED with entertaining diversions and RGB lights need to use the controller to achieve change effect, and each of the controller control distance, in general, a simple controller control distance for 10 to 15 meters, remote controller to control a distance of 15 to 20 meters, the longest can control to 30 meters distance. If the LED with the connection of the distance is longer, the controller can't control so long lamp tape, you will need to use power amplifier for tapping.
