Solution Overview
Problem
Existing lighting control systems for large facilities, such as warehouses and factories, face challenges in adjusting lighting parameters like sensor thresholds and timing intervals due to their physical location at or near the ceiling, making adjustments difficult, time-consuming, and risky.
Innovation Solution
A remote control system using infrared (IR) signaling allows users to adjust lighting parameters, including sensor thresholds and timing intervals, from a distance, and incorporates an ambient light sensor and dimmer to maintain light intensity, enabling safe and efficient control of lighting systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is positioned at or near the ceiling to control lighting in large facilities, then the lighting control function is achieved, but adjusting sensor thresholds and timing intervals becomes difficult, time-consuming, and risky
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the ceiling-mounted controller. This remote device communicates with the controller via infrared signals, allowing users to adjust lighting parameters from ground level without needing to physically access the ceiling-mounted controller, thereby eliminating safety risks while maintaining full control functionality
Solution Approach 2:
The patent replaces the mechanical approach of physically accessing and adjusting the controller at ceiling level with an infrared-based wireless communication system. The remote control device uses infrared signals to transmit adjustment commands to the controller electronically, substituting manual mechanical adjustment with automated electronic control
2Productivity
If the controller is positioned at or near the ceiling, then proper illumination control is achieved, but adjustment operations become time-consuming
Solution Approach 1:
The remote control device serves as a mediator that enables instantaneous parameter adjustment from ground level. Users can modify sensor thresholds, timing intervals, and other lighting parameters by simply pressing buttons on the remote device, which immediately transmits infrared signals to the controller, eliminating the time-consuming process of climbing ladders or using scaffolding to reach the ceiling-mounted controller
Solution Approach 2:
The system allows users to pre-configure and store multiple sets of lighting parameters in the controller's memory. When adjustment is needed, users can quickly recall and activate pre-configured parameter sets using the remote control device, significantly reducing the time required for adjustment operations compared to manually configuring each parameter from scratch

Implementation Method 1
A remote control device using infrared (IR) signaling permits a user to quickly and safely communicate with the lighting controller to adjust such parameters
Implementation Method 2
the lighting controller also includes an ambient light sensor and a dimmer that work in conjunction to maintain the light intensity of an activated light at a predetermined level
Data Source
AI summary
A lighting system includes a light emitting element operable to emit light at a level between zero and 100 percent, a light level sensor positioned to detect a total level of light, and a motion detector positioned to detect a motion in a predefined space. A controller is coupled to the light emitting element, the light level sensor, and the motion detector and is operable to compare a measured total level of light to a set point and to activate the light emitting element in response to the measured total light level being below the setpoint. The controller is further operable to activate the light emitting element in response to the detection of motion within the space.
