Context-Aware Lighting Device Location Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart lighting devices struggle to automatically adjust their light output according to different locations and contexts without user intervention, as they lack efficient methods to determine and adapt to new locations and environmental changes.
Innovation Solution
A lighting device equipped with a receiver and processor that determines its location based on signals from other devices, compares it to stored associations, and adjusts its light output accordingly, allowing for automatic application of pre-set light settings when moved to new locations or contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lighting device automatically adjusts light output based on location, then adaptability to different environments is improved, but device complexity increases due to added sensors and processing requirements
Solution Approach 1:
The lighting device automatically determines its own location using signals from other devices in the network and autonomously selects appropriate light settings without requiring manual user input. The processor compares current location data with stored location information and automatically applies the corresponding light settings, enabling the device to serve itself in adapting to different environments.
2Adaptability or versatility
If the device stores multiple location associations, then adaptability to different contexts is improved, but memory requirements and data management complexity increase
Solution Approach 1:
The system pre-stores associations between locations and appropriate light settings in memory before the lighting device needs to adapt. By having this location-setting mapping data prepared in advance, the device can quickly retrieve and apply the correct settings when moved to a new location, avoiding the need for complex real-time analysis or extensive new data storage.
3Measurement precision
If manual user input is required for each location change, then control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The lighting device continuously receives location information from other devices in the network and uses this feedback to automatically adjust its light output. The processor monitors location data, compares it with stored associations, and automatically applies the appropriate settings, creating a closed-loop system that maintains control precision without requiring manual user intervention.

AI summary
A lighting device (100) arranged for rendering a light output is disclosed. The lighting device (100) comprises at least one light source (102) arranged for emitting light. The lighting device (100) further comprises a receiver (104) arranged for receiving at least one signal from at least one further device (110), which at least one signal is representative of a current location of the lighting device (100). The lighting device (100) further comprises a processor 106 arranged for controlling the light output of the at least one light source (102). The processor (106) is further arranged for determining the current location of the lighting device (100) based on the received at least one signal and for accessing a memory (108) storing associations between locations and light settings. The processor (106) is further arranged for comparing the current location to at least one stored location so as to determine whether a first similarity criterion is met, and for controlling, if the first similarity criterion is met, the light output of the lighting device (100) according to a light setting associated with the stored location. This allows a user to move the lighting device (100) between locations, and for each location the previously set light setting associated with that location may be applied to the lighting device (100). The processor (106) is further arranged for associating the current location with a current light setting if the first similarity criterion is not met, and the processor (106) is further arranged for storing the association in the memory (108).
