Indoor Switch Controls Outdoor Motion Light Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor lights with motion detection or dusk-to-dawn features often operate inefficiently, requiring users to manually adjust settings located outdoors, leading to energy wastage and security concerns due to limited control over the lights' functionality and timing.
Innovation Solution
A circuit arrangement that allows users to control outdoor lights from an indoor light switch, featuring a motion detector and mode actuator, enabling adjustments to detection angles, on-time settings, and override functions, thereby improving energy efficiency and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If motion detector and control features are integrated into the outdoor light itself, then the light can autonomously detect motion and control operation, but adjusting settings becomes difficult and requires outdoor access
Solution Approach 1:
The system divides the control functionality into two separate locations: the outdoor light contains the motion detector and execution circuitry, while the indoor light switch houses the control interface and setting adjustment features. This segmentation allows autonomous operation at the light while maintaining accessible controls indoors.
Solution Approach 2:
An electrical connection between the indoor light switch and outdoor light serves as an intermediary communication channel. This connection transmits control signals and setting adjustments from the indoor switch to the outdoor light, enabling remote configuration without direct outdoor access.
2Extent of automation
If dusk-to-dawn feature is implemented with fixed sensor sensitivity, then the light automatically switches based on ambient light levels, but the light operates for extended periods including times when natural lighting is sufficient
Solution Approach 1:
The system transforms the fixed sensor sensitivity into a dynamic, user-adjustable parameter. The indoor light switch provides controls that allow users to modify the ambient light threshold and operational timing, enabling the system to adapt to different environmental conditions and reduce unnecessary operation during times when natural lighting is sufficient.
Solution Approach 2:
The patent enables changing the operational parameters of the dusk-to-dawn feature through the indoor light switch. Users can adjust sensitivity thresholds and timing settings, allowing optimization of energy consumption by preventing operation during times when ambient lighting levels are already sufficient for visibility.
3Reliability
If motion detector settings are fixed at the outdoor light, then the detection parameters remain constant, but the light may not operate as intended for security purposes requiring adjustable detection angles and locations
Solution Approach 1:
The control system is segmented between the outdoor motion detector and the indoor light switch. The outdoor detector maintains consistent operation while the indoor switch provides adjustable parameters for detection sensitivity, detection angles, and operational timing. This allows reliable detection while adapting to different security requirements and environmental conditions.
