JERCIO. SK6812 built-in IC - LED light ball four colors one SMD 5050RGB 256 grayscale adju

SK6812 built-in IC lamp bead product introduction:

SK6812 - built-in drive IC 5050RGB lamp bead

Is a built-in driver IC lamp bead upgrade, absorbed the advantages of previous generations of built-in lights, and experience Anew revise create an updated version of the built-in driver IC lamp bead.Obvious difference is that: before the driver IC for vertical fixed inside lamp bead, transverse fixed after the promotion, the big brand Ming micro IC compatible WS2812B, after the edition correction circuit is simpler transmission speed faster, lower pressure drop, a constant current, more stable performance...

Built-in IC lamp bead: to integrate the traditional driver IC encapsulation to 5050 RGB lights inside, all lines in the replace with gold thread, not only save the space to reduce the failure rate between the bonding pad, and shorten the transmission distance The transmission speed faster, more stable...

Traditional full-color series products need driver IC RGB lamp bead The mainest is need a lot of resistance capacitance, then one electronic components combined with a circuit board, experience among countless lines via sink copper, countless bonding pad...Although the customer's hand is just a small piece of finished product, it has been through countless processes.Inevitably sometimes there are "minor flaws" that are a failure rate.The presence of the built-in IC lamp has completely solved this traditional problem.Leap closer to the driver IC and the distance between the RGB lights, easy to eliminate the boss electronic engineers have a headache and inevitable problem will happen again...

SK6812 built-in IC lamp overview:

SK6812 is a set control charge.And luminescent electricity??An integrated intelligent external LED light source.Its exterior is the same as a 5050LED light bulb, each of which is a pixel.The inside of the pixels is included??Intelligent multiword interface data lock and plastic amplification drive.Power stabilized circuit, built-in constant current circuit, high accuracy RC oscillator, the output drive adoption patent PWM technology, valid guarantee??The color of the light within pixels is highly consistent. 

The data protocol is unipolar.Yards of communication methods, pixels in electricity after reset, DIN side accept from control machine transmission of data, first of all the 24 bit data is sent after the first pixel extraction, sent to the data latch pixels interior, the rest of the data through the internal plastic??Electricity??When the plastic is enlarged, the output is transferred from the DO port to the next level of pixels, each passing by a single pixel, and the signal is reduced by 24bit.The pixels point is the auto-shaping forward technology, so that the number of cascades in the pixels is the number of pixels.Restricted by signal transmission, only limited transmission speed??Requirements.

LED has low voltage drive, environmental protection energy saving,????High, scattering Angle??Big, consistent, low work??The advantages of super long life.Will control the electricity?Integrated with LED, electrical?Be??Simple, small, installation??Jane??It is.

SK6812 built-in IC lamp ball main application area:

LED full-color luminescent lamp string, LED full color module, LED, light bar, LED guardrail, LED appearance/scene lighting

LED point light source, LED pixel screen, LED screen, various electronic products, electrical equipment running lamp.

SK6812 built-in IC lamp character description:

Top SMD is integrated with high quality external single-strand serial cascade IC;

Control electricity??Integrated with RGB chips in the SMD 5050 components, a full external control pixel is formed, and the mixing effect is uniform and consistent.

Built-in data plastic??Any one pixel is received by the signal and then it is reprinted by the waveform, and the line is guaranteed.Waveform distortion?Will????Gal.

The built-in power reset and the power to reset the battery.You don't have any lights on.

Gray adjustment circuit (256 gray-scale adjustable),

The red light drives the special treatment, the color is more balanced,

Single line data transmission, infinite cascade.

Reconstructive retweeting technology, the transmission distance between two points exceeds 10M.

The data transmission frequency can be up to 800Kbps, when the speed is refreshed.30 frames per second, cascade??Less than 1024 points.

The built-in power back-up protection module is not damaged by the power supply.
