  • Publication number: 20230332763
    Abstract: A light board structure includes a board body, a wireless transceiver module and a light-emitting member. The wireless transceiver module and the light-emitting member are both installed on the board body. The wireless transceiver module has a feeder wire and a ground wire. The board body has a collision avoidance area, which runs through the board body and disposed to avoid collision with the wireless transceiver module and the light-emitting member. The feeder wire and the ground wire are positioned on a side of the collision avoidance area. The collision avoidance area is configured to emit a radio wave, and solve a problem that the communication distance of a light board structure is short. A light fixture having the light board structure includes an installation cavity. The collision avoidance area of the light board structure matches an inner wall of the installation cavity to form a collision avoidance channel.

  • Publication number: 20230093105
    Abstract: A method of dynamically loading an encryption engine generates a relationship between encryption identifiers and information parameters. The information parameters includes information security levels, information sizes, and information access speeds. The encryption identifiers include a soft encryption identifier and a hard encryption identifier. A target encryption identifier of current to-be-encrypted information is obtained, and a target encryption mode of the current to-be-encrypted information is determined. An encryption engine corresponding to the current to-be-encrypted information is loaded according to the encryption mode. The method can reduce waste of resources, and improve an efficiency of encryption and decryption of information.
