Overview - ISO/IEC TR 15067-2:1997 (HES Lighting Model)
ISO/IEC TR 15067-2:1997 is a Technical Report from ISO/IEC JTC 1 that defines a lighting application model for Home Electronic Systems (HES). It provides a physical and logical model for lighting control in residential automation and supplies a preliminary set of HES messages for exchanging commands, status and data among lighting components. The report is intended as a reference for modeling lighting components, interactions and use cases within an HES environment.
Key topics and technical content
- Physical lighting model
- Defines physical components: fixture (illuminator), switch, dimmer, sensor, device concentrator, user interface, user interface concentrator, and lighting system controller.
- Describes how HES interfaces are required on components or provided via concentrators, and how physical units map to logical units.
- Logical lighting model
- Introduces logical elements lighting activator (source of control signals) and illuminator (light source).
- Covers architectural variants: simple, complex, hierarchical, and distributed lighting systems to accommodate different intelligence and control strategies.
- Lighting use cases
- Provides example scenarios illustrating practical deployments: single-switch control, sensor-based ambient modulation, occupancy detection with delays, predefined scenes (lighting “moments”), and security-driven pseudo-random lighting.
- HES message framework
- Offers a preliminary message set and overview for commands, status reports and data exchange. Message examples in the report include relationships such as Activator–Illuminator, Activator–User Interface, Coordinator–Activator, and Activator/Coordinator–Other controllers.
Practical applications and users
- Who benefits
- System architects and integrators designing residential lighting control and HES interfaces.
- Product manufacturers building intelligent fixtures, dimmers, sensors, concentrators, and lighting controllers.
- Software developers implementing HES messaging, scene management, or distributed control logic.
- Standards bodies and test labs validating interoperability between HES lighting components.
- Use cases
- Designing interoperable home lighting solutions that support scenes, occupancy and ambient-light compensation.
- Mapping physical hardware to logical control models for software control and system integration.
- Defining message-level interactions for coordinated operation with other home subsystems (security, life-safety).
