Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ambience lighting systems face challenges when the number of light sources is large, as the central control unit must connect to each individual source, leading to impractical wire distribution and operational inefficiencies.
Innovation Solution
The system employs a central control unit that transmits color information to multiple local control units, which operate independently to manage light sources based on their position, allowing for efficient operation of a large number of light sources, including Light Emitting Diodes (LEDs), and can be connected in parallel or series.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a central control unit connects to each individual light source, then color control accuracy is improved, but device complexity and wiring complexity increase significantly
Solution Approach 1:
The system divides the control function into a central control unit that processes color information and multiple local control units that execute lighting control. Each local control unit is responsible for a specific region or set of light sources, segmenting the control task to reduce wiring complexity while maintaining color control accuracy through coordinated operation.
Solution Approach 2:
Local control units act as intermediaries between the central control unit and the light sources. The central control unit transmits color information to local control units, which then manage the actual light emission. This intermediary structure reduces the direct connection requirements between the central unit and numerous light sources.
2Area of stationary object
If the number of light sources is increased, then illumination coverage and visual effect are improved, but the number of connections from the central control unit becomes impractical
Solution Approach 1:
The control system is segmented into hierarchical levels: a central control unit for overall coordination and multiple local control units for regional management. This segmentation allows the system to scale to large numbers of light sources by distributing control functions locally, making the connection structure manageable even with extensive illumination coverage.
Solution Approach 2:
The control architecture transitions from a flat, direct-connect model to a hierarchical, multi-dimensional structure. Local control units are distributed across different spatial regions, creating a decentralized control network that can efficiently manage large numbers of light sources without requiring impractical connection densities from a single central point.
3Adaptability or versatility
If local control units operate independently, then system scalability is improved, but color consistency across different regions may deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms where local control units receive color information from the central control unit and adjust their operation accordingly. The central control unit coordinates the color output across all local control units based on the displayed image content, ensuring color consistency is maintained while allowing independent local operation for scalability.
Solution Approach 2:
Local control units are designed with universal functionality to handle various control tasks independently while following centralized coordination. Each local control unit can operate autonomously based on received color information, enabling the system to scale by adding more identical units without compromising overall color consistency through centralized color management.

AI summary
This invention relates to an ambience lighting system for use in conjunction with a display device including an image display region. A central control receives an incoming audio video stream (AVS) and to determines color information at the periphery of the image to be displayed. Light sources are disposed in a pre-fixed arrangement in relation to the periphery of the image display region, and local control units are coupled to open or more light sources selected from the multiple light sources for locally operating the at least one coupled light source. The central control unit is adapted to transmit the determined color information as a stream to each respective local control unit, which use a portion of the received color information to operate the at least one coupled light source, the portion being determined based on the position of the at least one coupled light source within the pre-fixed arrangement.
