1. Product Overview :
SK6812RGBW is a smart LED control circuit and light emitting circuit in one controlled LED source,
which has the shape of a 5050 LED chip. Each lighting element is a pixel, and the intensities of the
pixels are contained within the intelligent digital interface input. The output is driven by patented PWM
technology, which effectively guarantees high consistency of the color of the pixels. The control
circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high
precision RC oscillator.
The data protocol being used is unipolar NRZ communication mode. The 32-bit data is transmitted
from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an
internal data latch, the remaining data is passed through the internal amplification circuit and sent out
on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic
shaping forwarding technology makes the number of cascaded pixels without signal transmission only
limited by signal transmission speed.
The LED has a low driving voltage (which allows for environmental protection and energy saving),
high brightness, scattering angle, good consistency, low power, and long life. The control circuit is
integrated in the LED above.
2. Main Application Field:
● Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube,
LED appearance / scene lighting

TOP SMD LED Application Notes
1. Features
The Purposes of making LEDCOLOR’s customers and user s to have a clear understanding on the ways how to
use the LED.
2. Description
Generally. The LED can be used the same way as other general purposed semiconductors. When using
OPSCO’s TOP SMD LED, the following precautions must be taken to protect the LED.
3. Cautions
3.1. Dust & Cleaning
This emitter has a silicone surface, There are many benefits to the silicone surface in terms of optical
properties and improved reliability. However, silicone is a softer material and prone to attract dust. While a
minimal amount of dust and debris on the LED will not cause significant reduction in illumination, steps
should be taken to keep the emitter free of dust.
These include keeping the LEDs in the manufacturer’s package prior to assembly and storing assemblies in
an enclosed area after installing the emitters.
Surface condition of this device may change when organic solvents such as trichloroethylene or acetone
were applied.
Avoid using organic solvent, it is recommended that isopropyl be used as a solvent for cleaning the LEDs.
When using other solvents, it should be confirmed beforehand whether the solvents will dissolve the
package and the resin of not.
Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence as ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power. Baking time and assembled
condition. Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will
occur.
3.2. Moisture Proof Package
In order to avoid the absorption of moisture during transportation and storage, LED are packed in the
aluminum envelop, A desiccant is included in the aluminum envelop as it absorbs moisture. When
moisture is absorbed into the AMT package it may vaporize and expand during soldering. There is a
possibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the
LEDs. For this reason, the moisture proof package is used to keep moisture to a minimum in the package.
3.3. Storage
In order to avoid the absorption of moisture, It is recommended to store SMD LED (in bulk or taped) in the
dry box (or the desiccator ) with a desiccant, Otherwise to store them in the following environment as
recommended.
a. Temperature: 5℃~30℃
b. Humidity: 60% RH Max
It is recommended to solder the LED as soon as possible after unpacking the aluminum envelop, But in case
that the LED have to be left unused after unpacking envelop again is requested.
The LED should be soldering within 1 hours after opening the package.
If baking is required, A baking treatment should be performed as follows:
70℃±5℃ for more than 24 hours.
3.5 Heat Generation:
Thermal design of the end product is of paramount importance. Please consider the heat generation of the
LED when making the system design. The coefficient of temperature increase per input electric power is
affected by the thermal resistance of the circuit board and density of LED placement on the board, as well as
components. It is necessary to avoid in tense heat generation and operate within the maximum rating given in
this specification. The operating current should be decided after considering the ambient maximum
temperature of LEDs
3.6 Electrostatic Discharge & Surge Current :
Electrostatic discharge (ESD) or surge current (EOS) may damage LED.
Precautions such as ESD wrist strap, ESD shoe strap or antistatic gloves must be worn whenever handling of
LED.
All devices, equipment and machinery must be properly grounded.
It is recommended to perform electrical test to screen out ESD failures at final inspection.
It is important to eliminate the possibility of surge current during circuitry design.
3.7 Moisture Proof Package
Cannot take any responsibility for any trouble that are caused by using the LEDs at conditions exceeding
our specifications.
The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent looking
directly at the LEDs with unaided eyes for more than a few seconds.
The formal specification must be exchanged and signed by both parties before large volume purchase begins.
The appearance and specifications of the product may be modified for improvement without notice.
