Lifud LED Driver Paired With D4i Sensor Creates Smart Streetlight Upgrades
Leave a message
Every streetlight in the city at night is a beacon of light protecting travelers. When intelligent sensing meets efficient driving, Lifud's new D4i sensor SAD040M, paired with the D4i Lifud LED Driver power supply ACD series, creates a truly intelligent lighting control system. This makes every light an energy feedback node for smart cities, bringing a smarter, more energy-efficient, and more reliable solution for outdoor lighting.

1. Precise Sensing, Making Light "Understand" Scenarios
Imagine this scenario: automatically lowering brightness when no one is around at night to avoid light pollution and energy waste; accurately capturing the movement of pedestrians and vehicles, brightening the lights when they approach to ensure travel safety; automatically supplementing light in real-time monitoring of ambient brightness, rainy days, and smoggy days to maintain a comfortable lighting level… This is the charm of the Lifud SAD sensor!
Supports DALI Motion Sensor (303): Accurately detects moving targets, with a maximum sensing height of 12 meters and a maximum sensing range of 15 meters, perfectly covering standard road scenarios.
Supports DALI Light Sensor (304): Automatically determines whether to turn lights on or off or adjust brightness based on ambient light levels, making full use of natural light and further saving energy.
Based on Sensor-Based Autonomous Control: No complex host system is required; the sensor can independently complete policy control, allowing for more flexible deployment when used with Lifud D4i street light power supplies.

2. Standard Interface, Plug and Play, Strong Compatibility
The Lifud D4i sensor SAD040M adopts the international standard Zhaga Book18 interface, perfectly adapting not only to Lifud ACD series Lifud LED Drivers but also compatible with other brands of D4i lighting products. Plug and play, flexible adaptation, and simple and quick installation and maintenance!

3. Lifud LED Driver D4i Power Supply: The Heart of Smart Lighting
As the core driver of the entire system, the Lifud LED Driver LF-ACD series DALI-2 & D4i street light power supply provides powerful support for smart lighting:
- Data Energy Feedback: Supports DALI Part 251, 252, and 253, ensuring each light has a "health record."
- Comprehensive Protection: Includes input overvoltage/undervoltage, open circuit, short circuit, and overtemperature protection. It also supports external NTC resistor monitoring of lamp temperature. Lightning protection ratings reach L-N 6KV and L/N-PE 10KV, ensuring safer outdoor use.
