Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light source systems for stage lighting and image projection fail to provide two distinct multi-color light sequences suitable for different working modes, such as 2D and 3D projection displays, resulting in unsatisfactory color saturation and brightness.
Innovation Solution
A light source system incorporating a color wheel with multiple segments that can rotate to generate different light sequences by switching between areas with distinct wavelength conversion materials, allowing for the generation of red, green, blue, and white lights, and tailored light sequences for specific display modes using a driving device and switching mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional color wheel with single set of segments is used, then the system structure is simple, but only one light sequence can be generated which cannot satisfy different working modes
Solution Approach 1:
The color wheel is divided into multiple independent segment sets (first segments and second segments), each set capable of generating different light sequences. This segmentation allows the system to switch between different working modes by selecting different segment sets, thereby improving adaptability while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The color wheel is designed with multi-functionality by incorporating multiple segment sets that can generate different light sequences (first light sequence and second light sequence) for different working modes. This universal design enables a single color wheel structure to serve multiple purposes: generating RGBW light sequence for one mode and RGB light sequence for another mode, eliminating the need for separate color wheels for each function.
2Adaptability or versatility
If a color wheel with multiple segment sets is implemented, then different light sequences for different working modes can be generated, but the device complexity increases
Solution Approach 1:
The color wheel incorporates dynamic switching capability through the driving device, which can rotate the color wheel to different positions to select between first segments and second segments. This dynamic configuration allows the system to adapt between different working modes in real-time, improving versatility while the automated driving mechanism helps manage the complexity of having multiple segment sets.
Solution Approach 2:
The driving device acts as an intermediary mechanism that manages the complexity of switching between different segment sets. By providing automated control for rotating the color wheel to appropriate positions, the driving device simplifies the operation of the multi-segment color wheel, making the increased structural complexity manageable through intelligent control.
3Illumination intensity
If a conventional light source system is used, then the system structure is simple, but color saturation is poor and brightness is insufficient
Solution Approach 1:
Different segment sets in the color wheel are designed with specific local qualities optimized for different working modes. The first segments are configured with wavelength conversion materials optimized for generating the first light sequence with high brightness and saturation, while the second segments are optimized for the second light sequence. This local optimization ensures high illumination quality for each mode without requiring a completely different light source system.
Solution Approach 2:
The color wheel segments incorporate wavelength conversion materials that convert excitation light to specific wavelengths, creating composite optical structures. These composite materials enable the system to generate highly saturated colors and high brightness by converting a single excitation source into multiple wavelength components, improving illumination quality without proportionally increasing system complexity.

AI summary
A light source system using an excitation light source and a multi-segmented color wheel device with wavelength conversion materials is disclosed. The color wheel device includes a first area having two or more first segments and a second area having two or more second segments for receiving the excitation light. The color wheel device is driven by the driving device periodically, so that a first light sequence is generated by the two or more first segments in the first working mode and a second light sequence is generated by the two or more second segments in the second working mode. The first light sequence is different from the second light sequence. The first and second working modes are switched by a switching device. The light source system may be used in image projection system generating two or more different lights sequences in different working modes.
