Ambient Lamp Controller for Multi-Strip Lighting Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp technologies struggle to coordinate the lighting effects across multiple light strips, leading to inefficiencies and suboptimal performance in achieving desired lighting effects.
Innovation Solution
A method and device for coordinated playback of lighting effects across multiple light strips, involving the determination of a lighting-effect coordination mode and sub-frame duration, and the calculation of refresh time slots for each light strip based on the total number of lighting units in each group, allowing for synchronized or sequential playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single light strip control is used, then the control system is simple, but it cannot meet the actual needs of multi-light strip coordinated lighting effects
Solution Approach 1:
The patent segments the control system by introducing the concept of light strip groups, where each group contains one or more light strips. The controller divides multiple light strips into separate groups and controls each group independently through group control commands, enabling coordinated lighting effects across multiple light strips while maintaining manageable system complexity through modular group-based control architecture
Solution Approach 2:
The controller is designed with multi-functional capabilities to handle both single light strip control and multi-light strip group coordination. It can process group control commands that apply to multiple light strips simultaneously, while also maintaining compatibility with traditional single light strip control modes, thus providing universal control functionality that adapts to different application scenarios
2Manufacturing precision
If multiple light strips are controlled independently, then each light strip can be controlled precisely, but the coordinated playback of lighting effects across light strips is difficult to achieve
Solution Approach 1:
The patent introduces light strip groups as intermediary entities between the controller and individual light strips. The controller sends group control commands to light strip groups, which then coordinate the playback across member light strips. This intermediary structure simplifies coordinated control by abstracting away the complexity of individual light strip management while maintaining precise playback accuracy through group-synchronized control
3Reliability
If refresh time slots are determined based on total lighting units in each light strip group, then coordinated playback is achieved, but the calculation and distribution of time slots becomes complex
Solution Approach 1:
The patent changes the basis for determining refresh time slots from individual light strip characteristics to group-level parameters. By calculating time slots based on the total number of lighting units within each light strip group rather than individual strip properties, the system achieves coordinated playback through group-based parameterization, simplifying the overall calculation framework while improving reliability

AI summary
A lighting-effect coordinated playback method for an ambient lamp includes: obtaining a target lighting-effect including at least one sub-frame lighting-effect to be played by multiple light strips, and determining a lighting-effect coordination mode and a sub-frame duration of the target lighting-effect; determining a light strip group to which each light strip belongs according to the lighting-effect coordination mode, and determining a refresh time slot of each light strip relative to the sub-frame duration according to a total number of lighting units of the light strip contained in each light strip group; and according to the corresponding refresh time slot of each light strip, sending frame-slice control data of each frame slice of the light strip corresponding to the frame lighting-effect to the corresponding light strip at intervals, so as to control the light units of each corresponding light strip to coordinately complete playback of the sub-frame lighting-effect.
