Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stroboscope light sources, such as xenon flash lamps and RGB LEDs, struggle to provide high light energy with short light pulses and fail to achieve an equienergy mixture of visible wavelengths, limiting their effectiveness in creating stroboscope effects and colored illumination.
Innovation Solution
An illumination device with two sections: one section using variable-spectrum LEDs (e.g., RGB LEDs) and another using fixed-spectrum white LEDs, allowing for synchronized or asynchronous control to achieve high-energy light flashes and colored effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If xenon flash lamps or RGB LEDs are used as light sources, then high light energy with short light pulse can be achieved, but an equienergy mixture of visible wavelengths (white light) cannot be realized
Solution Approach 1:
The patent combines two different illumination sections with distinct spectral characteristics: one section produces white light (equienergy mixture of wavelengths) while the other produces colored light. This merging allows the system to achieve both high light energy and proper spectral distribution simultaneously, resolving the contradiction between energy concentration and spectral balance.
Solution Approach 2:
The illumination device is designed with multi-functional capability by incorporating both white light and colored light sections. The white light section provides the equienergy spectral mixture needed for stroboscope effects, while the colored section enables color variation, making the system universally applicable for both stroboscope and colored illumination purposes.
2Adaptability or versatility
If RGB LEDs are used for colored illumination, then color variability can be achieved, but energy density for stroboscope effects is insufficient
Solution Approach 1:
The illumination device is segmented into functionally distinct sections: one dedicated to white light production for stroboscope effects with high energy density, and another dedicated to colored light production for color variability. This segmentation allows each section to optimize its specific function without compromise, enabling both stroboscope effects and color variability to coexist.
Solution Approach 2:
By merging the white light section (optimized for energy density and stroboscope effects) with the colored light section (optimized for color variability), the system achieves both high power/energy density and adaptability. The sections work together to provide comprehensive illumination capabilities that neither section could achieve alone.
3Adaptability or versatility
If standard illumination means with color screens or colored LEDs are used, then colored stage lighting can be achieved, but stroboscope effects cannot be realized
Solution Approach 1:
The device is divided into specialized sections where the white light section is optimized for stroboscope effects with appropriate temporal characteristics (flash duration, frequency), while the colored section handles colored illumination. This segmentation ensures that stroboscope reliability is not compromised by the presence of colored illumination components.
Solution Approach 2:
The illumination device achieves multi-functionality by integrating both stroboscope-capable white light section and colored illumination section. This allows a single device to reliably perform both stroboscope effects and colored stage lighting, eliminating the need for separate devices and ensuring both functions can be realized simultaneously or independently.

AI summary
An illumination device includes two illumination sections. The first illumination section includes a plurality of illumination elements that are each configured to emit light in a light spectrum, wherein the light spectrum is variable. The second illumination section includes one or several illumination elements that are each configured to emit light in a fixed light spectrum, wherein the fixed light spectrum is white.
