Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a dimming sheet is used to shield the light emitting area or electronic dimming is used for LED light sources, then the luminance of the stage light can be adjusted from 0 to 100%, but the color temperature of the light changes with luminance, causing the stage atmosphere to not meet requirements
Solution Approach 1:
The patent applies color changes principle by using a color temperature compensation sheet with different color values that can be switched in and out of the light path. When the dimming sheet reduces luminance, the compensation sheet adjusts the color temperature by filtering specific wavelengths, ensuring the color temperature remains consistent across different luminance levels. The compensation sheet contains color temperature compensation regions with different color values (e.g., blue for warm light compensation, yellow for cool light compensation) that are selectively positioned in the light path based on the required color temperature adjustment.
2Temperature
If a color temperature compensation sheet with different color values is switched in and out of the light path, then the color temperature can be compensated in real time, but the device structure becomes more complex
Solution Approach 1:
The patent merges the color temperature compensation sheet with the existing dimming sheet mechanism, allowing both sheets to be controlled by the same driving mechanism. The compensation sheet is positioned adjacent to or integrated with the dimming sheet in the light path, sharing common mounting structures and control systems. This merging approach reduces overall device complexity while maintaining color temperature compensation functionality.
Solution Approach 2:
The driving mechanism is designed to control both the dimming sheet and color temperature compensation sheet, making it a multi-functional device. The same motor and control system that adjusts luminance also manages color temperature compensation by switching the compensation sheet in and out of the light path. This universal control approach reduces the number of separate components and simplifies the overall system structure.
