A New Choice for Smart Streetlight Upgrades: Lifud D4i Sensor — Empowering Every Light with Intelligence!
Every streetlight in the city at night is a glimmer of light safeguarding your journey. Lifud’s new D4i sensor SAD040M combines with the D4i streetlight LED driver ACD series, where smart sensors meet efficient LED drivers to create a truly intelligent lighting control system. This turns every light into an energy feedback node for the smart city, delivering a smarter, more energy-efficient, and more reliable solution for outdoor lighting.

Precise Sensing, Making Lights “Scene-Aware”
Picture this: Lights dim automatically in the empty dead of night, cutting light pollution and energy waste; they detect the motion of pedestrians and vehicles with precision and brighten up as they approach, ensuring travel safety; ambient brightness is monitored in real time, with automatic light compensation on rainy or smoggy days, maintaining a comfortable lighting level at all times... This is the power of the SAD sensor!

1. DALI motion sensor (303) supported: Precisely detects moving targets, with a max sensing height of 12m and a max detection range of 15m, perfectly covering standard road scenarios.
2. DALI light sensor (304) supported: Automatically switches lights on/off or adjusts brightness based on ambient light, making the most of natural light for greater energy savings.
3. Sensor-based autonomous control: No complex host system required. The sensor can independently execute strategic control. When it is paired with Lifud D4i streetlight LED drivers, the deployment is more flexible.
Standard Interface, Plug and Play, Strong Compatibility
The Lifud D4i sensor SAD040M features the international standard Zhaga Book18 interface. It not only perfectly matches Lifud ACD series drivers but also is compatible with D4i lighting products of other brands — realizing plug-and-play, flexible adaptation, and easy installation and maintenance!

D4i LED Driver: The Heart of Smart Lighting
As the core of the entire system, the LF-ACD Series DALI-2&D4i Street Light Driver provides robust support for smart lighting:
1. Data & energy feedback: DALI Part 251, 252, 253 supported, creating a “health profile” for every street light.
2. Comprehensive protection: Complete with over/under voltage, open circuit, short circuit and over-temperature protection. It also supports external NTC resistors for temperature monitoring, with a protection level of up to L-N 6KV and L/N-PE 10KV, ensuring total peace of mind for outdoor use.
