Virtual Object Mapping for Luminaire Lighting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected lighting systems face challenges in rendering external lighting scenes designed by third-party users, as these scenes may not account for the specific setup of the user's lighting system, leading to difficulties in mapping lighting content effectively across different setups.
Innovation Solution
The use of 'virtual objects' defined by their location and influence value in a virtual space allows for the determination of lighting settings for luminaires in a physical space, enabling the rendering of lighting effects without prior knowledge of the specific lighting system setup, where the influence value acts similarly to a gravitational pull, adjusting light characteristics based on separation and influence radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting scenes are designed for specific lighting system setups, then the lighting effect can be precisely controlled for that setup, but the scene cannot be effectively applied to different lighting system configurations
Solution Approach 1:
The patent creates a virtual copy of the physical lighting environment by defining virtual objects that mirror physical luminaires. This virtual model allows lighting scenes to be designed and rendered without direct dependency on specific physical setup configurations, enabling cross-platform compatibility while maintaining precise control over lighting effects.
Solution Approach 2:
The patent introduces a virtual space dimension that separates lighting scene design from physical system constraints. By mapping physical luminaires to virtual objects in a conceptual space, the system enables lighting content to be created and adjusted independently of the actual physical configuration, then projected onto various setups through coordinate transformation.
2Reliability
If lighting scenes are customized for each user's specific setup, then the lighting effect is optimized for that setup, but the effort and time required to create and adapt scenes increases significantly
Solution Approach 1:
The patent performs preliminary mapping between physical luminaires and virtual objects during system initialization or setup phase. This pre-established correspondence allows lighting scenes to be quickly adapted to different configurations without requiring time-consuming manual adjustment, as the virtual model already contains the structural relationships needed for automatic rendering.
Solution Approach 2:
The system automatically adapts lighting scenes to different physical configurations by utilizing the pre-defined virtual object mappings. The control device autonomously calculates the appropriate transformation and applies the lighting scene without requiring manual intervention from the user, thereby maintaining high rendering quality while minimizing adaptation time.
3Adaptability or versatility
If a universal lighting scene format is created, then it can be applied to any lighting system setup, but it loses the ability to account for specific setup characteristics
Solution Approach 1:
The patent applies local quality by allowing different virtual objects to have specific properties and characteristics that correspond to their physical counterparts. Each virtual object can maintain unique attributes (such as position, intensity, color temperature) that preserve the specific characteristics of the physical luminaire it represents, while the overall system remains universally applicable through the virtual modeling framework.

AI summary
A method of controlling a luminaire at a first physical location in a physical space to render a lighting effect in the physical space, the method being performed by a control device and comprising steps of: receiving at least one data object for use in rendering the lighting effect, the data object defining at least one virtual object comprising an influence value for the virtual object and a coordinate vector denoting a virtual location of the virtual object in a virtual space; determining the first physical location of the luminaire in the physical space from a map of the physical space; determining a separation between the first physical location of the luminaire and a second physical location in the physical space corresponding to the virtual location of the virtual object in the virtual space; and controlling at least one characteristic of light emitted by the luminaire as a function of the determined separation and the influence value for the virtual object, thereby rendering the lighting effect.
