  • Patent number: 10473300
    Abstract: A light source assembly comprises a base body and at least one light source module. The base body comprises a first and a second bearing base connected to each other. The first bearing base is configured for an image capture module to be disposed thereon. The second bearing base is located on the periphery of the first bearing base. The at least one light source module is slidably disposed on the second bearing base, and movable toward and away from the first bearing base. The at least one light source module forms an adjustable space. The adjustable space is configured for receiving the image capture module. The first bearing base has a first bearing surface configured for the image capture module to be disposed thereon. A sliding direction of the at least one light source module is not parallel to a normal direction of the first bearing surface.

  • Publication number: 20160112609
    Abstract: A monitoring apparatus includes a main body, a mounting plate, and a fixing plate. The mounting plate is connected to the main body and has a first bending rib structure protrusively formed thereon. The fixing plate is fixed to a mounting target and is disposed opposite to the mounting plate. The fixing plate has a first opening structure formed thereon corresponding to the first bending rib structure and a second bending rib structure laterally extending from the first opening structure. When the mounting plate is connected to the fixing plate to make the first bending rib structure pass through the first opening structure, the first bending rib structure rotates with rotation of the mounting plate relative to the fixing plate to be engaged with the second bending rib structure, so as to fix the mounting plate to the fixing plate.
