Spatial Light Coding for Lighting System Commissioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of commissioning lighting systems with multiple light sources is tedious and requires manual entry of addresses, making it difficult to control and configure light sources effectively for desired light effects.
Innovation Solution
A spatial coding system is used to create and capture light patterns, allowing light sources to encode their attributes, such as position and address, which can be decoded by a light pattern capturing device to simplify the commissioning process and enable easy control of lighting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual address entry is used for commissioning light sources, then individual addressability of light sources is achieved, but the commissioning process becomes tedious and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical process of address entry with an automated optical detection system. A detection device captures images of light patterns emitted by light sources, and a processing unit automatically decodes the spatial information to assign addresses, eliminating the need for manual address input and significantly reducing commissioning time while maintaining accurate address assignment
Solution Approach 2:
The light sources themselves provide the commissioning information through emitted light patterns that encode their spatial position and identity. The detection device automatically reads these self-generated patterns, allowing the system to commission itself without external manual intervention for address assignment
2Adaptability or versatility
If temporal light coding is used for controlling light sources, then light source identification is enabled, but wallwasher light sources cannot be properly commissioned
Solution Approach 1:
The patent transitions from temporal light coding (time-based modulation) to spatial light coding (position-based patterns). By projecting distinct spatial light patterns in different dimensions and positions, the system can encode information that is readable by the detection device, enabling proper commissioning of wallwasher light sources while maintaining compatibility with other light source types
3Quantity of substance
If a high number of light sources are installed, then comprehensive lighting coverage is achieved, but the complexity of determining and programming addresses increases
Solution Approach 1:
The patent replaces the complex manual process of determining and programming addresses for numerous light sources with an automated image-based detection system. The detection device captures spatial light patterns and the processing unit automatically extracts position information to assign addresses, reducing the commissioning complexity from O(n) manual operations to a single automated scanning process regardless of the number of light sources
Solution Approach 2:
The system creates a digital copy of the physical light source arrangement by capturing images of spatial light patterns and processing them to generate address assignments. This digital representation automatically maps the physical configuration to the control system, eliminating the need for manual address programming for each light source

AI summary
Disclosed are methods and systems for controlling of a lighting system with a plurality of light sources, particularly to the semi-automatic commissioning of light sources of the lighting system or controlling of the creation of lighting scenes with the lighting system. A spatial coding of light is used for controlling a lighting system, particularly for commissioning of light sources of the lighting system. Some exemplary systems for controlling a lighting system with a plurality of light sources, include a light system controller for controlling the light sources to create a spatial light pattern coding one or more attributes of the light sources, and a light pattern capturing device comprising a scanner for capturing the created spatial light pattern and a communication unit for communicating with the light system controller in order to enable the controlling of the one or more light sources based on the captured spatial light pattern.
