This invention discloses a video advertising projection device for exhibitions with multi-wide-angle lighting functions, including an exhibition video advertising projector, a dynamic attitude adjustment component, an intelligent color-tuning and soft light diffusion component, and a light path shaping and light-cutting component. The exhibition video advertising projector has a spotlight drive chamber installed inside, and the dynamic attitude adjustment component is installed inside the spotlight drive chamber. The intelligent color-tuning and soft light diffusion component is installed on the outer surface of the dynamic attitude adjustment component, and the light path shaping and light-cutting component is installed inside the intelligent color-tuning and soft light diffusion component. This invention constructs a dynamic adjustment mechanism for the spotlight attitude through the coordinated operation of an electric push rod, a telescopic rod, a micro servo motor, and a counterweight. This avoids the defects of mirror reflection, whitening, and blurring caused by the fixed-angle wide-angle direct illumination of the spotlight on the advertising screen. Through the mutual cooperation of a dimming plate, a drive motor, and gears one and two, intelligent switching between warm and cool colors and stepless adjustment of light intensity are achieved.

A beamforming design method for intelligent metasurface arrays based on orthogonal time-frequency-space technology includes: aggregating multipath channels under direct illumination into cascaded channels with near-field direction vectors; randomly initializing the phase shift of intelligent metasurface units; establishing an effective channel matrix based on the cascaded channels; then establishing a multi-user and rate objective function; maximizing the objective function through phase shift optimization using a hierarchical search strategy; repeatedly executing the hierarchical search strategy to search and optimize subsequent blocks until the number of intelligent metasurface units in each block reaches a preset value; then performing an exhaustive search in the final block, thus completing one iteration; repeating the iteration until the maximum number of iterations is reached; outputting the final optimal phase shift; and implementing beamforming design based on the final optimal phase shift. This invention can reduce the complexity of beamforming design and ensure reliable transmission of high capacity during high-speed movement.

This invention discloses a non-direct three-dimensional light wall lighting system and method for stacked aquaculture channels, relating to the field of aquaculture lighting technology. The system includes multiple LED uniform light lamps arranged along the length of the stacked aquaculture channel. Each LED uniform light lamp includes an LED light-emitting component, a light-transmitting uniform light structure, and a lateral light-limiting structure. The lateral light-limiting structure limits the effective light output width of the LED uniform light lamp in the channel width direction, while the light-transmitting uniform light structure allows the light emitted by the LED light-emitting components to continuously diffuse in the channel height direction, thereby forming a three-dimensional light wall extending along the channel length direction, limited in the channel width direction, and covering multiple aquaculture layers in the channel height direction within the channel space between the stacked cages. The three-dimensional light wall is spaced apart from the facade of the stacked cages, so that the facade of the stacked cages is mainly illuminated by scattered light, refracted light, or diffused light within the channel space, rather than by direct illumination from the main beam of the lamps. This invention can improve the uniformity of illumination in the upper, middle, and lower layers of the stacked aquaculture cages, while allowing the low-position lamps to be installed at a higher height, avoiding obstruction of the passage of work vehicles, inspection vehicles, or inspection robots.
