Solution Overview
Problem
Gaming machines with dedicated lighting controllers face inefficiencies such as increased power consumption, electromagnetic interference, and complex programming, which can increase costs and development time.
Innovation Solution
Integrate a display controller that extracts lighting data from graphical data and converts it into lighting control parameters, eliminating the need for a separate lighting controller, thereby reducing power draw and electromagnetic interference while simplifying programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If a dedicated lighting controller is used to control lighting assemblies, then lighting control functionality is achieved, but power consumption increases
Solution Approach 1:
The patent combines the lighting control functionality with the existing display controller into a single integrated component. The display controller is modified to include both display output capabilities and lighting control capabilities, eliminating the need for a separate dedicated lighting controller. This merging reduces the overall power consumption of the system while maintaining full lighting control functionality.
Solution Approach 2:
The display controller is designed to perform multiple functions: it controls both the display device and the lighting assemblies. By making the display controller universal, the system eliminates redundant components and reduces power consumption associated with having separate dedicated controllers for each function.
2Object-affected harmful factors
If a dedicated lighting controller is used, then lighting control is achieved, but electromagnetic interference increases
Solution Approach 1:
By merging the lighting control function into the display controller, the patent reduces the number of separate electronic components in the system. Fewer separate controllers mean fewer sources of electromagnetic interference, thereby reducing overall EMI while maintaining lighting control capabilities.
3Ease of operation
If a dedicated lighting controller with separate programming protocol is used, then lighting control precision is achieved, but programming complexity increases
Solution Approach 1:
The display controller is enhanced to handle both display and lighting control using a unified programming interface. This allows developers to control both display content and lighting effects through the same codebase and programming logic, significantly reducing programming complexity while maintaining precise synchronization between display and lighting.
Solution Approach 2:
The patent implements a homogeneous control approach where both display and lighting are controlled through the same controller using consistent programming methods. This eliminates the need to learn and manage multiple different programming protocols, making the system easier to program while maintaining precise control synchronization.

Function Achieved in This Case
This approach reduces power consumption and electromagnetic interference, simplifies lighting control development, and enhances synchronization between display content and lighting effects.
Implementation Method 1
a lighting assembly including at least one light-emitting device
Data Source
AI summary
A gaming machine includes a cabinet, a display device, a lighting assembly including at least one light-emitting device, game-logic circuitry that conducts one or more casino wagering games and generates graphical data, and a display controller communicatively coupled to the display device and the lighting assembly. The graphical data includes display data and lighting data as pixel values. The display controller causes the display device to present display content associated with the one or more casino wagering games. The display controller receives the graphical data from the game-logic circuitry, extracts the lighting data and the display data from the graphical data, converts the lighting data from pixel values to lighting control parameters accepted by the lighting assembly, causes the display device to present the display content based on the display data, and causes the lighting assembly to emit light based on the lighting control parameters of the lighting data.
