Solution Overview
Problem
Prior art lighting systems using passive infrared sensors can only detect moving objects but cannot determine their type or direction, leading to inefficient energy usage and unsuitable lighting activation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If passive infrared sensors are used to detect moving objects, then the lighting fixture can be controlled to turn on or off, but the system cannot determine the type of moving object, causing false activation when non-target objects like birds are detected
Solution Approach 1:
The patent introduces an image capturing device as an intermediary between the sensor and the control system. This device captures images of detected objects, and image processing analyzes these images to identify object types. This intermediary step enables accurate differentiation between target objects (humans) and non-target objects (birds), resolving the false activation problem while maintaining efficient lighting control
Solution Approach 2:
The patent replaces the insufficient passive infrared sensor detection mechanism with a more advanced image-based detection and recognition system. By substituting simple thermal detection with visual image capture and processing, the system gains the capability to identify object types, thereby eliminating false activations from non-target objects while preserving the automated lighting control function
2Ease of operation
If passive infrared sensors are used to detect moving objects, then the lighting fixture can be activated, but the system cannot determine the moving direction of objects and cannot turn on the lighting fixtures in advance
Solution Approach 1:
The patent implements preliminary action by using image processing to predict the moving trajectory of detected objects. The system analyzes the direction and speed of movement captured in images, forecasts where the object will be, and activates lighting in advance at the predicted location. This eliminates the time delay associated with waiting for objects to enter detection range, while maintaining automatic control
Solution Approach 2:
The patent employs feedback mechanisms where the image capturing device continuously monitors object movement, and the processing system uses this information to adjust and update lighting control decisions in real-time. This closed-loop feedback enables the system to track moving objects and maintain optimal lighting activation based on current object position and predicted trajectory, achieving both automation and timely response

AI summary
An illuminating control system for controlling a plurality of illuminating devices is disclosed herein. The illuminating control system includes an image capturing device and a processor. The image capturing device is configured to capture images of an object. The processor is coupled to the image capturing device. The processor is configured to receive the images and determine whether the object is a predetermined object based on the images. If the processor determines that the object is the predetermined object, the processor controls the image capturing device to track the object to obtain a moving condition of the object. The processor turns on one of the illuminating devices correspondingly based on the moving condition of the object.
