General description:

WS2812B-V5 is an intelligent control LED light source in the control circuit and RGB chips are integrated into a package of 5050 Size. It internally includes an intelligent digital port data latch and signal-reshaping amplification drive circuit. Also includes a precision internal oscillator and a voltage-programmable constant current control part, effectively ensuring the pixel point light color height is consistent.

The data transfer protocol uses a single NZR communication mode. After the pixel power-on reset, the DIN port receives data from the controller, The first pixel collects initial 24bit data and then sends it to the internal data latch, and the other data which is reshaped 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 24bit. pixel adopt auto reshaping transmit technology, making the pixel cascade number not limited to the signal transmission, only depending on the speed of signal transmission. RESET time>280μs, it won't cause a wrong reset while interruption, and it supports the lower frequency and inexpensive MCU.
Refresh Frequency updates to 2KHz, Low Frame Frequency, and No Flicker appear in HD Video Camera, which improves excellent display effect.

LED with low driving voltage, environmental protection, energy saving, high brightness, a large scattering angle is large, good consistency, low power, long life, and other advantages. The control chip integrated with the LED above becomes more simpler circuit, a smaller volume, and convenient installation.

Top SMD LED Using Instructions

Summary:
To make the best use of WORLDSEMI’s LED, please refer to the below precautions, they are of the same usage method as other electronic components

Cautions:

2.1. Dust & Cleaning:

The surface of the LED is encapsulated with modified epoxy resin because it plays a very good role in protecting the optical performance and aging resistance. The modified epoxy resin is easy to stick with dust and must be kept clean. When there’s a certain amount of dust on the surface of the LED, it won’t affect brightness, but dustproof should be taken care of. Promoting the use of unsealed packages in preference to others and the assembled LEDs should be placed in a clean container.

Avoid using the organic solvents to clean the dust on the LED surface and it’s necessary to confirm whether the cleaning fluid will dissolve the LED.

Do not clean the LEDs by the ultrasonic. Some parameters affecting the LED performance must be evaluated if have no alternative but to the ultrasonic cleaning method, such as ultrasonic power, baking time assembly conditions, etc.

2.2. Moisture-proof packaging

TOP SMD LEDs are moisture-sensitive components. LEDs are packaged in aluminum foil bags to prevent them from absorbing moisture during transport and storage. A desiccant is placed in the bags to absorb moisture. If the LED absorbs moisture, then it evaporates and expands when in the reflow process, which may break the colloid from the bracket and damage the optical performance of the LED. For this reason, moisture-proof packaging is to prevent them from absorbing moisture during transport and storage. The moisture resistance rating of WORLDSEMI’s LED is LEVEL 5a.

2.3 Management after unpacking:

(1). Please use the LED under the condition of “T<30℃， RH<60%”
(2). Use up within 24 hours after removing the packages.
(3). We would recommend dehumidification if they exceed the valid storage period of products or are dampened due to other reasons.

2.4 Management of Dehumidification:

LED products exceed the prescribed time limit or are damp for other reasons. It is recommended to use them after dehumidification. Demand for dehumidification: 75℃/>24H.

3. SMT Reflow
   
   Referring to the parameters listed below, the experimental results prove that the TOP SMD LED meets the JEDEC J-STD-020C standards. As a general guideline, it is recommended to follow the SMT reflow temperature curve recommended by the solder paste manufacturer.

Remarks:
1). These general guidelines may not apply to all PCB designs and reflow soldering configurations.
2). All temperatures referred to are measured on the surface of the package body.

4. Assembly Precautions
5. Clip the LED from its side.
6. Neither directly touch the gel surface with the hand or sharp instrument, it may damage its internal circuit.
7. Not to be double stacked, it may damage its internal circuit.
8. Can not be stored in or applied in the acidic sites of PH<7.
