LED Chip Pixels DC 5V SK6812 WWA(White+Warm white+ Amber) SMD 5050 (similar WS2812B) Individually Addressable Digital
1. Product Overview :
SK6812WWA 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 24-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.

The Purposes of making Normand’s customers and users to have a clear understanding on the ways how to use the LED.
Generally. The LED can be used the same way as other general purposed semiconductors. When using Normand’s TOP SMD LED, the following precautions must be taken to protect the LED.
3.1. Dust & Cleaning
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.
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: 5c~30c 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:
70c±5c for more than 24 hours.
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.
