Solution Overview
Lighting is about 20–30% of a building's electricity use. In China, lighting consumes more than 600 billion kWh a year. Conventional circuits are switched in coarse steps, cannot follow demand, have no scene logic, and depend on people to find faults, so a large share of that energy is wasted. The Green Building Evaluation Standard from the Ministry of Housing and Urban-Rural Development and national standard GB 50034, Standard for Lighting Design of Buildings, both set requirements for energy and visual comfort. This solution uses IoT control so lighting is finer, scene-based, and automatic, with lower energy use and a more comfortable visual result.
It covers homes, offices, retail, industry, roads, and landscape lighting. Smart luminaires, dimming drivers, sensors, and gateways support continuous dimming, color-temperature changes, one-touch scenes, occupancy and daylight sensing, schedules, and sunrise–sunset logic. DALI, Zigbee, Bluetooth Mesh, and LoRa connect through the IoT platform for central monitoring, fault alarms, and energy analysis. In practice, energy use falls 30–50%, lamps last longer, and maintenance costs drop.
| Conventional lighting | Smart lighting | |
|---|---|---|
| Control | Manual switches, fixed brightness | Sensing, dimming to demand |
| Energy | Baseline | 30–50% less energy |
| Maintenance | Walk-round inspections, late fault finding | Remote monitoring, early fault warning |
| Scenes | One mode | Several scenes, one command |
Where Energy Is Lost, and How to Start
Commercial buildings and industrial parks often leave lights on outside working hours. Road lighting follows a fixed clock and does not respond to traffic or weather. Offices rarely offer human-centric light, which shows up in comfort and in how people work. Start with the heavy loads: underground garages, corridors, and roads. Add sensors and a gateway in stages rather than replacing every fitting at once. Tie lighting into the BMS so it can follow air conditioning and blinds. Choose products that follow DALI-2 and Zigbee 3.0 so the devices can work together.
