Daylight Sensor Programming via Visible Light Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing daylight sensors and other lighting control devices are difficult to program once installed, as they may not be easily accessible, leading to challenges in initial and subsequent programming.
Innovation Solution
A system that uses visible light control signals transmitted via a mobile device to program daylight sensors, allowing users to input settings and adjust parameters through a user interface, with the mobile device modulating a light source to send corresponding signals to the sensor, which can then adjust its settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If push-button programming is used at the daylight sensor, then programming capability is provided, but ease of operation deteriorates due to inaccessibility after installation
Solution Approach 1:
A mobile device with a light source acts as an intermediary to transmit programming signals to the daylight sensor. The mobile device displays programming instructions and transmits visible light control signals that the sensor can detect and process, eliminating the need for direct physical access to the sensor's push buttons.
Solution Approach 2:
The mechanical push-button interface is replaced with an optical communication system. Instead of requiring physical button presses at the sensor location, the system uses visible light signals transmitted from a mobile device to convey programming information wirelessly to the sensor.
2Loss of time
If automatic set-point programming is implemented, then programming time is reduced, but manufacturing precision deteriorates due to automatic determination of parameters
Solution Approach 1:
The system provides dynamic programming modes that can switch between automatic and manual configurations. Users can select automatic set-point programming for quick setup or manual programming through the mobile device interface for precise parameter control, allowing the system to adapt to different user needs and situations.

Data Source
AI summary
A lighting control system includes a daylight sensor configured to receive visible light control signals to set or adjust one or more parameters of the daylight sensor including, e.g., a set point (i.e., an acceptable lighting level). The lighting control system also includes a non-transitory computer program product that includes programming instructions that may be downloaded to, e.g., a mobile device and/or may be executed by a processor or like device. The programming instructions may be configured to provide a user interface related to the daylight sensor, receive via the user interface one or more user inputs related to the daylight sensor, and modulate a light output of a light source to transmit visible light control signals corresponding to the received one or more user inputs. Methods of programming a daylight sensor with visible light control signals are also provided, as are other aspects.
