Target Lighting Layer
Patent: US9894736B2
GIS-based maps specifying desired illumination levels for every zone in your coverage area.
- Crosswalks: 20 lux
- Major roads: 11-18 lux
- Local streets: 7 lux
- Sidewalks: 2 lux
- Building footprints: 0 lux
Dynamic variations for Halloween, late night, migratory bird protection, demand response, and special events.
Optimization Engine
Patent Pending: 18/660,680
AI-accelerated system that finds the optimal dimming level (0-100%) for each luminaire.
- Tests thousands of configurations in minutes
- Accounts for overlapping beam spreads
- Uses real-world geometry (slopes, intersections, mast arm positions)
- Generates in-house labeled training data
Human eyes cannot perceive brightness changes under 20%—significant optimization headroom exists.
Dynamic Scheduling
Priority-based calendar resolving which lighting instruction runs at any given time.
Priority hierarchy (highest to lowest):
- Emergency dispatch (CAD integration)
- Grid emergency (demand response)
- Transportation safety
- Crime prevention
- Special events
- Environmental protection (BirdCast)
- Default operating profile
Higher priorities are never degraded for lower ones.
NLC Integration
API communication with your existing lighting control platforms.
We receive:
- Asset inventory
- Luminaire locations
- IES file assignments
- Current schedules
We send:
- Optimized per-luminaire dimming
- Schedule assignments
Currently integrated with 2 major lighting control systems.
Processing Speed
For a 2,000-light project:
- Traditional method: Days to weeks
- Photometrics AI: 3-5 minutes
Standards Compliance
Photometrics AI optimizes to meet:
- ANSI/IES RP-8 (US roadway lighting)
- CIE 115 (International)
- AS/NZS 1158 (Australia/New Zealand)
Typical compliance rate: 91-97% of calculation points meet or exceed standards.
What Photometrics AI Adds (vs. NLCs alone)
Your networked lighting controls provide the infrastructure—communications, metering, health monitoring, on/off control.
Photometrics AI adds the intelligence:
- Photometric optimization based on actual physics
- Per-luminaire dimming (not one-size-fits-all)
- Standards compliance verification
- Dynamic context-aware scheduling
- Multi-priority resolution
