Product Details
I. Solution Overview
II. Core Hardware Functions
-
Automotive-grade LED Driver Module
Designed for vehicle 12V constant power supply with flicker-free constant-current driving circuit, compatible with RGB, RGBW and dual-CCT LEDs. Stable output current ensures uniform brightness and eliminates flickering caused by voltage fluctuation and driving electrical interference.
-
Intelligent Control & Interaction Module
Equipped with dedicated low-power automotive MCU, supporting physical button, infrared remote, mobile APP via Bluetooth and voice control. Pre-programmed lighting effects include breath fade, running water chasing, music sync rhythm, strobe and zonal color shifting; users can customize brightness, color and running speed. Special vehicle logic such as welcome light upon door opening and delay-off after engine shutdown is available.
-
Multi-protection Vehicle Power System
Built-in multi-protection against overvoltage, undervoltage, reverse polarity, overcurrent, short circuit, surge and ESD static discharge to cope with engine cranking voltage swing, ignition EMI and extreme temperature. Power-off memory function automatically restores previous lighting mode after power reboot.
-
Signal Expansion Module
Optional CAN bus connection to original vehicle ECU for linkage with door signal, turn signal and brake lamp; cascade connection and independent zonal control for multiple light strips are supported. Reserved audio trigger interface enables auto color change synchronized with music beats.
-
Structure-Optimized Layout
Slender rigid PCB or flexible FPC design with miniaturized components, anti-bending and anti-vibration performance for narrow hidden interior installation, excellent high-temperature and moisture resistance.
III. Key Advantages
- Automotive-grade Reliability: Wide-temperature-range components with strong anti-EMI performance, stable operation without flicker or crash under vehicle vibration, drastic temperature difference and unstable power supply.
- Excellent OEM Compatibility: Universal 12V design fits most vehicle models, plug-and-play non-destructive wiring and original car host linkage to meet mainstream aftermarket refitting demands.
- Flexible Intelligent Customization: Lighting modes, linkage logic and APP functions can be developed on demand; expandable features include music rhythm, scene preset and timing switch.
- Cost-effective Mass Production: Standardized SMT layout with commonly used components guarantees high automated production yield for large-volume aftermarket orders.
