What is D4i? 

The Smart Lighting Upgrade from DALI-2 Certification

Developed by the Digital Illumination Interface Alliance (DiiA), the D4i protocol (DALI for Intra-Luminaire) builds on the IEC 62386 standard and DALI-2 certification to deliver three groundbreaking IoT lighting capabilities:

(Keywords: D4i protocol, IEC 62386, IoT-enabled luminaires)

✅ IoT Lighting Integration: Embedded data collection (temperature/power monitoring)

✅ Smart Dimmable Drivers: NFC programming + 24V auxiliary power supply

✅ Lighting Energy Management: Real-time energy reporting & predictive maintenance

3 Key Benefits of D4i Certification｜Why Choose D4i Smart Lighting?

Energy-Efficient Lighting Technology

Compared to traditional DALI-2 systems, D4i-certified luminaires reduce energy consumption by 40% through adaptive dimming algorithms. Built-in energy metering (compliant with Part 252) enables per-fixture analytics for optimized lighting energy management.

Seamless Smart Lighting System Integration

Featuring D4i drivers with NFC connectivity, the system enables rapid deployment in applications like:

Remote fault diagnosis for smart street lighting

Automated light recipes in vertical farms

Multi-zone synchronization in sports venues

Robust IoT Lighting Infrastructure

IP67-rated D4i power supplies (e.g., Suretron series) operate reliably from -40℃ to +85℃, while Part 253-compliant diagnostics extend hardware lifespan by 50%.
