Low Power & Intelligent Sensing: LongJoin New-Generation Streetlight Controller for More Energy-Efficient & Smarter Urban Lighting

Product Introduction

Selected Q&A for Daily Communication

Q1: How do streetlights equipped with intelligent controllers cope with complex and variable external environments at night?

1. The 7 Series microwave induction controller is equipped with anti-false-trigger microwave technology and dynamic adjustment, which effectively filter interferences such as wind, small animals, light flickering and microwave interference, avoiding false triggers while maintaining high sensitivity for human/vehicle detection.
2. It adopts a reflected light compensation mechanism. High-performance sensors combined with sophisticated software algorithms ensure anti-interference against the luminaire’s own light and ambient light from passing vehicles.
3. It supports light decay compensation. Through dynamic sensing and optimized software algorithms, it maintains stable lighting performance throughout the luminaire’s service life even as brightness degrades over time.

Q2: What are the energy-saving advantages of the 7 Series microwave induction controller compared with traditional light-sensing controllers?

1. The standard 7 Series features light sensor + microwave dual detection. Parameters can be customized via infrared remote control, supporting 0–10V / DALI 2.0 dimming.
   
   
   When no pedestrians or vehicles are present at night, the luminaire operates at low brightness; when people or vehicles pass by, brightness increases to meet lighting needs. This greatly reduces power consumption and extends luminaire lifespan.
2. The IoT version adds the LongJoin self-developed UM9900 Smart Streetlight Management System. Users can remotely set multi-period dimming strategies via the platform according to actual road lighting demands, achieving precise energy saving at scheduled times.

Q3: What are the highlights of the self-developed UM9900 Smart Streetlight Management System?

1. Users can monitor real-time streetlight status (brightness, voltage, current, signal strength, alarm information, etc.) and customize parameters and operating strategies via the UM9900 system.
2. The system supports access via web portal and WeChat Mini Program for flexible real-time monitoring and control, significantly reducing operation and maintenance costs compared with traditional manual inspection.

Core Technical Q&A

1. How energy-efficient is the low-power consumption of the 7 Series?

2. What is the difference between microwave induction and PIR induction?

• Microwave induction: Detects moving objects via electromagnetic waves, with strong penetration; not blocked by glass or walls, suitable for complex scenarios.
• PIR induction: Only detects human infrared radiation, with better anti-interference performance; ideal for residential areas, schools and other places with strict anti-false-trigger requirements.

3. What is the practical value of the wide DC voltage design?
