Conventional illumination systems struggle to simultaneously adjust the distribution angle of light in two directions effectively.
Innovation Solution
A control device for an illumination system that includes a detection device with a distribution angle adjustment region and a processing device to generate data for controlling the distribution angle of light based on the movement of an adjustment object on a touch sensor, allowing simultaneous adjustment in two directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional illumination systems use a light source combined with a thin lens or liquid crystal element to control light distribution, then the distribution angle can be adjusted in one direction, but simultaneous adjustment in two directions (X and Y) is not achieved
Solution Approach 1:
The patent extends the control from one dimension to two dimensions by arranging multiple detection elements in both X and Y directions on the touch sensor. The display panel shows distribution angle adjustment objects that can be moved independently in both directions, enabling simultaneous two-directional control of light distribution angles.
Solution Approach 2:
The touch sensor and display panel serve multiple functions: they detect user input, display the current state, and control both X and Y direction distribution angles through a unified interface. The processing device generates control signals for both liquid crystal cells simultaneously, making the system multi-functional.
2Measurement precision
If the distance between light source and thin lens is changed to adjust distribution angle, then light distribution can be controlled, but precise simultaneous control in two directions is difficult to achieve
Solution Approach 1:
The patent replaces mechanical adjustment mechanisms with a touch-based electronic control system. Users interact with the display panel to adjust distribution angles, and the processing device converts these inputs into control signals for the liquid crystal cells, eliminating complex mechanical linkages while improving precision.
Solution Approach 2:
The system provides visual feedback on the display panel showing the current position of distribution angle adjustment objects and the resulting light distribution pattern. This allows users to see the effect of their adjustments in real-time and make precise corrections.
