1Length of moving object
If manual control or fixed communication channel remote control is used, then device operation is simple, but control range is limited and energy management is inefficient
Solution Approach 1:
The patent replaces traditional mechanical remote control systems (RF/IR buttons) with a photosensitive control system that uses light as the control medium. The light source device emits directional light that can be modulated to carry control signals, which are then detected by the photosensitive device to generate control signals for the controller. This substitution enables long-distance control without the range limitations of conventional remote controls.
Solution Approach 2:
The patent introduces light as an intermediary carrier for control signals. The light source device modulates light intensity or patterns to encode control information, which then travels through space to the photosensitive device. This intermediary approach allows control signals to be transmitted over long distances while maintaining simplicity in the control interface.
2Measurement precision
If directional light is used for control, then control precision is improved, but light guide device complexity increases
Solution Approach 1:
The light guide device is segmented into multiple light guide units, each corresponding to a specific photosensitive unit or control target. This segmentation allows the system to guide light precisely to different locations independently, improving control precision while keeping each individual light guide unit relatively simple in structure.
Solution Approach 2:
Different regions of the light guide device are designed with different optical properties to guide light to specific photosensitive units. Each light guide unit is optimized for its specific function, creating local quality variations that enable precise light direction while maintaining overall system simplicity.

AI summary
A photosensitive control system includes a light source device configured to provide a directional light beam and a photosensitive device which includes at least one pre-arranged photosensitive unit. Also, the photosensitive control system has a light guide device configured between the light source device and the photosensitive device for guiding the light beam to the at least one photosensitive unit and therefore the photosensitive device produces a sensing signal. In addition, the photosensitive control system includes a controller configured to receive the sensing signal and provide control data in accordance with the sensing signal.
