Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems lack the ability to efficiently control the intensity and color of LED light sources to create dynamic lighting effects and synchronized shows across multiple devices.
Innovation Solution
A lighting control system that includes a control circuit in each lighting device capable of receiving and storing show information and auxiliary information, allowing it to independently control the intensity and color of light emissions based on predefined functions and commands, enabling synchronized shows across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous communication is used for adjusting intensity and color of lighting devices, then real-time control is achieved, but communication bandwidth demands increase and delays or errors occur
Solution Approach 1:
The patent applies preliminary action by pre-defining show information including intensity tracks and color tracks that specify the desired lighting effects over time. The lighting control system receives this show information in advance, processes it locally, and executes the show without requiring continuous real-time communication during execution. This reduces communication bandwidth demands while maintaining timing accuracy through local processing of the pre-received show data.
2Stability of the object's composition
If multiple lighting devices are coordinated through continuous communication, then synchronized light shows are achieved, but communication delays and errors increase
Solution Approach 1:
The patent applies segmentation by dividing the show information into separate tracks (intensity tracks and color tracks) that can be processed independently by each lighting device. Each device receives the segmented show information and executes its portion locally based on its own characteristics, reducing the need for continuous inter-device communication and minimizing synchronization errors while maintaining coordinated output.
3Ease of operation
If show information is processed centrally with continuous instructions, then coordinated control is achieved, but communication requirements increase
Solution Approach 1:
The patent applies self-service by enabling each lighting device to autonomously process show information and generate control signals based on its own characteristics and the pre-received show data. The system performs local processing of intensity and color tracks, determining control signals independently without requiring continuous external instructions, thereby reducing communication bandwidth while maintaining coordinated control across multiple devices.
Data Source
AI summary
A lighting device may include one or more light sources, a load control circuit configured to control an amount of power delivered to each of the one or more light sources, and a control circuit for controlling the load control circuit to control an intensity level and a color of the cumulative light emitted by the one or more light sources. The control circuit may be configured to generate a show. For example, the control circuit may be configured to receive, via the communication circuit, show information and auxiliary information from a computing device in one or more messages. The control circuit may be configured to store the show information and the auxiliary information in memory of the lighting device. The control circuit may be configured to receive, via the communication circuit, a command to execute a show in a message, and in response, generate the show.
