SOWIN provides a human-centric adaptive tunnel lighting system for tunnel entrances, threshold zones, transition zones, interiors and exits. The control chain can connect portal luminance sensors, traffic inputs, CH-800 gateways, intelligent lighting cabinets, circuit controllers and SLC810/SLC910 lamp-level controllers.
Measured exterior luminance, traffic conditions and approved zone curves allow the system to coordinate output instead of relying on one fixed entrance scene. Project-configured CCT, ramp rates, local fallback and manual authority help preserve visual continuity when weather, traffic or communication conditions change.
Final luminance levels, zone lengths, sensor locations, dimming curves and CCT settings depend on tunnel geometry, design speed, pavement, portal orientation, luminaire optics, local standards and witnessed site acceptance.
Build the project around adaptive tunnel lighting, tunnel lighting control system, black-hole and white-hole mitigation and 2700K–6000K adaptive CCT with clear authority, local continuity and owner-readable evidence.
Procurement decision: Approve wider deployment only after a representative pilot proves the offered control chain, local behavior, failure response, returned states and recovery method.
Highway, mountain, urban, subsea and long tunnels where portal conditions, traffic speed, weather or operating mode change enough to make one fixed lighting curve inefficient or visually abrupt.
Short, low-speed tunnels that already meet verified visual and safety criteria with stable local scenes and do not require networked sensing, lamp feedback or adaptive operation.
Define power, communication, data, command priority, timeout, local fallback, manual control and third-party responsibilities before connecting systems.
Preserve owner access to settings, records, credentials, backups, compatible spares, restoration instructions and supplier-transition responsibilities.

| Condition | Required Behavior | Witness Method |
|---|---|---|
| Portal sensor error | Reject implausible or stale values and apply an approved conservative scene. | Inject missing, stale and out-of-range values during FAT/SAT. |
| Communication loss | Continue approved local zone schedules and safety scenes. | Disconnect the central route and verify local operation and later reconciliation. |
| Abrupt scene change | Apply approved ramp rates and transition limits. | Witness transitions under representative day, night and weather inputs. |
| Gateway restart | Restore the approved configuration without uncontrolled output changes. | Restart a representative gateway under load and confirm zone state recovery. |
Define topology, operating scenes, authority, interfaces, alarms, local continuity and required evidence.
Record field assets, electrical and communication conditions, environmental limits and owner dependencies.
Use a representative section to test the functions carrying the highest project uncertainty and confirm the rollback route.
Verify the offered hardware, software, configuration, failure cases, records, backups and data export.
Align field inputs, predefined commands, returned states, alarms, maintenance workflow and final recovery.
Deliver owner credentials, configurations, records, permissions, spares and tested restoration procedures.
Scale authorization: Proceed beyond the pilot only after exceptions are closed or formally accepted and the owner approves the FAT/SAT evidence format.
Record the responsible party, required evidence, approval method and long-term operating consequence.
