COB LED Strip Features

This product uses COB (Chip On Board) packaging technology, where multiple LED chips are directly integrated onto a substrate to form a continuous light‑emitting surface. Compared to traditional SMD LED strips, it offers the following characteristics:

• More uniform light emission: no visible granularity, presenting a continuous and soft light band effect
• Softer light: reduces point‑source glare, more suitable for close‑range illumination
• More compact structure: higher luminous density per unit area
• Cleaner visual appearance: ideal for ambient lighting, decorative lighting, and display applications

COB LED strips are particularly suitable for scenarios that require high light uniformity, such as indoor ambient lighting, cabinet lighting, backlighting, and commercial display illumination.

Cutting Point Description

The product supports cutting at 12.5mm intervals. Cut along the marked cutting points. Be sure to disconnect the power before cutting.

Protocol Description

This product uses a single‑wire serial communication programmable driver IC (compatible with WS2812B LED communication timing) and transmits data using NRZ (Non‑Return to Zero) code.

The LED strip has a segmented control structure. Each IC controls one light‑emitting segment, with 12 segments per meter (83.3mm/segment). Each segment supports three‑channel dimming (RGB), with 8 bits per channel, totaling 24 bits of data.

After power‑on, the IC receives data from DIN. After receiving 24 bits, it latches the current data and forwards the remaining data to the next stage via DO. During this process, it does not accept new data; it outputs corresponding PWM signals to control brightness based on the received data.

When a RESET signal (low level ≥ 200μs) is input, the IC updates the display and starts receiving data again. Until a RESET signal is received, the display state remains unchanged.

Data Transmission

Note: D1 is data sent by the MCU; D2, D3, D4 are data automatically reshaped and forwarded by the cascaded circuit.

24‑bit Data Structure

Note: Data is transmitted MSB first, in the order GRB.

Timing Waveform

This product uses a unipolar return‑to‑zero code; every symbol must have a low level. Each symbol starts with a high level, and the high level time width determines whether it is a "0" code or a "1" code.

Input Code Pattern

Symbol	Parameter	Typical	Tolerance	Unit
T	Symbol Period	1.2	-	us
T0H	0 code, high level time	0.3	±10%	us
T0L	0 code, low level time	0.9	-	us
T1H	1 code, high level time	0.9	±10%	us
T1L	1 code, low level time	0.3	-	us
Trst	Reset code, low level time	≥ 200	-	us

Note: When programming, the high level time of the "0" code and "1" code must strictly follow the specified ranges. The low level time of the "0" code and "1" code only needs to be less than 20 µs.

Current / Power Requirements

The maximum power consumption of this product is approximately 12W per meter, with an operating voltage of 5V, so the maximum operating current per meter is approximately 2.4A.

When selecting a power supply, it is recommended to leave some margin; the power supply rating should be at least 1.25 times the maximum power consumption to ensure long‑term stable operation.

When multiple strips are cascaded, voltage drop along the line may occur. It is recommended to provide power compensation at regular intervals via auxiliary power cables to avoid uneven brightness or color deviation.
