Smart Lighting Parking Guidance Solution
An efficient, energy-saving and intelligent parking-lighting experience driven by IoT and AI vision
Includes light-based parking guidance, ramp running lights and smart energy management.
1. Project background
High-end residences, private clubs and hotels increasingly demand a higher-quality parking service. Traditional guidance relies on static signs, barriers and staff. Its limitations include:
Drivers must search for spaces themselves, and locating a space in a large underground garage takes time.
Ramps and aisles remain lit continuously, consuming energy without targeted control.
Guidance is uniform and cannot provide differentiated service for different user identities.
This solution combines license plate recognition, wireless IoT lighting control and microwave radar sensing to provide integrated light-based space guidance and ramp running lights.
It actively guides the vehicle from entry to parking while balancing experience and operating efficiency.
2. Market context and positioning
Parking guidance products generally fall into two groups: space detection and guidance systems using ultrasonic, video and guidance displays;
and smart-lighting control systems focused on dimming, colour and scene control.
The two groups have clear boundaries. Parking-guidance vendors generally cannot control individual luminaires or use light as a route.
Lighting vendors generally cannot recognise plates or plan routes. The market lacks an integrated solution that combines lighting with active space guidance.
This solution connects the two capabilities into a complete plate recognition -> route planning -> luminaire control loop.
It avoids separate procurement and deployment of lighting and guidance systems and provides differentiated value through both intelligent illumination and active space guidance.
3. Applicable scenarios
3.1 High-end villas and private estates
Independent underground garages can serve owners and visitors. Plate recognition automatically matches a dedicated space,
light paths guide the vehicle to it and ramp running lights illuminate along the route.
3.2 Private clubs and premium venues
Membership operation requires differentiated service. The system configures light-guidance strategies by membership level and switches lighting modes with one click for events.
3.3 Hotels and Grade-A office buildings
The system provides dedicated light guidance to VIP spaces and links to visitor reservations. A reserved visitor automatically enters the guidance process after arrival.
4. System components
4.1 Light-based space-guidance system
Entrance and exit cameras collect plates. The platform matches the plate to a space, plans a driving route and sends commands through a data gateway to the luminaires along the route.
The luminaires turn on in sequence to form a guiding light band.
Workflow
The vehicle enters; the camera captures the plate and uploads it to the platform.
The platform identifies the user, matches the space and selects the lighting strategy.
The platform plans the best route from the current position to the target space.
The gateway sends commands; luminaires along the route turn on sequentially.
4.2 Ramp running-light system
Microwave radar sensors are installed at both ends of the ramp. When a vehicle enters, the radar triggers luminaires section by section in a
defined sequence and interval to create a dynamic flow of light. After the vehicle leaves, the luminaires dim gradually after a delay. When no vehicle is present,
they remain at low brightness or enter sleep mode.
Workflow
The entrance radar detects a vehicle and triggers forward lighting from the first luminaire to the end.
When the vehicle exits, the exit radar triggers reverse lighting from the end back to the first luminaire.
After departure, the lights dim gradually to low brightness or sleep mode after the configured delay.
The system ignores new triggers until the current cycle ends to avoid conflicting light states.
5. System architecture
The solution uses four layers: sensing -> computing -> control -> display. A data gateway connects the layers and distributes commands.
| Layer | Function |
|---|
| Sensing | Plate-recognition cameras and microwave radar collect vehicle identity and position |
| Computing | Server platform and data gateway match plates, allocate spaces, plan routes and generate lighting strategies |
| Control | Constant-voltage controllers and IoT luminaires execute on/off, brightness , colour-temperature and timing control |
| Display | Energy-management platform and mobile terminals show luminaire status, energy data and guidance records and support remote strategy adjustment |
Deployment
All equipment uses a wireless self-organising networking protocol. Existing garages can be upgraded without damaging the current decoration,
and installation is significantly faster than traditional wired solutions.

7. Tiered service strategies
| User type | Light-guidance method | Scenario |
|---|
| Owner | Dedicated lights across the site; running lights welcome the vehicle along the full route | Private villa garage |
| VIP guest | Dedicated light band from entrance to VIP space | Club or estate reception |
| Family member | Direct light guidance to the member' s dedicated space | Daily villa parking |
| Visitor | Guide to a temporary visitor space and illuminate the route | Reserved or temporary visitor |
| Event mode | All lights linked on and running lights fully on | Tastings, banquets and parties |
8. Advantages
| Dimension | Traditional solution | This solution |
|---|
| Functional completeness | Lighting and guidance are separate systems | Integrated lighting and active space guidance |
| Guidance method | Static signs or displays ; driver judges the route | Active light guidance follows the light path |
| Differentiated service | Same guidance for every user | Strategies configured by user and scenario |
| Deployment | Wired installation damages decoration and takes longer | Wireless self-organising network ; install and use immediately |
| Energy management | Lights remain on and energy use is high | Lights turn on for vehicles and dim after departure with visible energy data |
| Expansion | Closed system with limited third-part y integration | Layered open architecture for integration and extension |
