10. Controller Recommended Data Transmission Time
| Timing Name | Min. | Typical | Max. | Unit | |
|---|---|---|---|---|---|
| T | Symbol period | 0.9 | 1.20 | 20 | µs |
| T0H | “0” code, high-level time | 0.20 | 0.30 | 0.40 | µs |
| T0L | “0” code, low-level time | 0.70 | 0.90 | — | µs |
| T1H | “1” code, high-level time | 0.70 | 0.90 | 1.00 | µs |
| T1L | “1” code, low-level time | 0.20 | 0.30 | — | µs |
| Reset | Reset code, low-level time | > 200 | — | — | µs |
- The protocol uses a unipolar return-to-zero code. Each symbol must contain a low-level period.
- Each symbol starts with a high level; the high-level duration determines whether it is a “0” or “1” code.
- When writing firmware, the minimum symbol period should be 1.2 µs.
- The low-level time of “0” and “1” codes must be less than 20 µs.

13. 24-bit Data Structure

High bit is sent first. Data is transmitted in GRB order: G7 → … → G0, R7 → … → R0, B7 → … → B0.
14. Typical Application Circuit

In practical circuits, to prevent instantaneous high voltage damage to the IC signal pins caused by hot-plugging during
testing, series protection resistors should be added at both the data input and output terminals.
Decoupling capacitors between each LED are essential for stable operation.
- Application 1: For soft or hard light strips with short distance between LEDs, use protection resistors
R1 and R2 of approximately 500 Ω at the signal input and output. The exact value should be determined by actual signal tests. - Application 2: For modules or general shaped products with longer transmission distance between LEDs,
the value of the series protection resistors depends on wire type and distance, and should be determined by actual usage.
15. Photoelectric Characteristics
The device exhibits typical relationships between pad temperature and relative luminous flux, wavelength characteristics,
and a typical radiation pattern of 120°. For detailed curves, refer to the original graphs:
- Relative luminous flux vs. pad temperature (RED / GREEN / BLUE)
- Relative spectral distribution vs. wavelength
- Typical radiation pattern (120°)
16. Packaging Standards
Surface-mount LEDs are supplied on reels, packed in anti-static bags, and then placed in cardboard boxes.
The cardboard box protects the LEDs from mechanical impact during transportation but is not waterproof.
Moisture-proof and waterproof measures should be taken during storage and handling.
- Reel size: 165/330 × 12 mm
- Each reel can hold up to 2000 / 8000 LEDs
- Anti-static polyethylene bag with desiccant and humidity indicator card
- Outer hard cardboard box, up to 20 bags per box
