Smart Lighting Systems

Smart lighting (e.g., tunable bulbs, smart switches, strip lights) requires components that support dimming, color temperature adjustment, wireless control, and energy efficiency. Key components include:

LED Drivers:

TI LM3445 (non-isolated, 85V–265V AC input, ±3% current accuracy) for dimmable smart bulbs, supporting TRIAC/0-10V/PWM dimming and 120dB wide dynamic range (WDR) for smooth brightness transitions.

Dialog iW3612 (isolated, 5W–20W output) for high-power strip lights, integrating PFC (power factor >0.95) to meet EN 61000-3-2 energy standards and reduce harmonic distortion.

Wireless Control Modules:

Nordic nRF52840 (BLE 5.3 + Zigbee 3.0 dual-protocol, <5μA standby current) for bulb-to-gateway communication, enabling group control (up to 50 bulbs per network) and scene automation (e.g., “movie mode”).

Silicon Labs EFR32MG24 (Matter-compliant, -104dBm receive sensitivity) for long-range connectivity (up to 100m line-of-sight), ideal for large homes or multi-floor installations.

Color & Brightness Control ICs:

ams AS7343 (8-channel spectral sensor, 350–900nm wavelength) for RGBW color calibration, ensuring ±2% color accuracy across bulb batches.

TI LP5024 (4-channel LED controller, 120mA per channel) for 256-level grayscale adjustment, supporting 2700K–6500K tunable white and 16 million RGB colors.
