Abstract: The disclosure provides an electronic device, including a circuit board, multiple semiconductor components, a first light reflecting structure, and a second light reflecting structure. The circuit board includes a substrate, and the substrate may have a first surface and at least one side surface. The multiple semiconductor components are disposed on the first surface. The first light reflecting structure is disposed on the first surface. The second light reflecting structure is disposed on the first surface and the at least one side surface.

Abstract: A rotary mechanism includes a supporter and a bracket. The supporter includes a body, a pivot portion and a support portion. The body whereon the pivot portion is disposed is disposed on a base. The support portion includes a bar and a guiding structure. A low end of the bar is connected to the body, and the guiding structure is disposed on a top end of the bar. The bracket includes a frame, a constraint portion, a pivot slot structure and a contact portion. The constraint portion and the pivot slot structure are disposed on the frame. The contact portion slides along the guiding structure when the bracket rotates relative to the supporter, so that position of the pivot portion moves from an end to the other end of the pivot slot structure structure, and the constraint portion contacts against the body for constraint rotation of the bracket.

Abstract: A rotary mechanism includes a supporter and a bracket. The supporter includes a body, a pivot hole structure and a guiding portion. The pivot hole structure and the guiding portion are disposed on the body. A slot is formed on the pivot hole structure. A top of the guiding portion is a cam structure. The bracket pivots to the supporter. The bracket includes a frame, a constraining portion and a pivoting portion. A bottom of the frame contacts against the guiding portion and slides relative to the cam structure. The constraining portion and the pivoting portion are disposed on the frame. The constraining portion can contact against the body to constrain rotation of the bracket relative to the supporter. The pivoting portion slidably pivots to the slot. The pivoting portion moves along the slot to contact the constraining portion against the body.

Abstract: A light-emitting device includes a light source, a panel and a light guiding structure. The light guiding structure includes a first light guiding tunnel and a second light guiding tunnel. The first light guiding tunnel includes a first end and a second end. A first opening is formed at the first end and close to the light source. The second light guiding tunnel includes a first end and a second end. The first end of the second light guiding tunnel communicates with the second end of the first light guiding tunnel. A diameter of the second end of the second light guiding tunnel is greater than a diameter of the first end of the second light guiding tunnel. A second opening is formed at the second end of the second light guiding tunnel. A diameter of the second opening is greater than a diameter of the first opening.

Abstract: An electronic device includes a case set and a case set detachment structure. The case set includes a first case with a plurality of fastening parts, and a second case with a plurality of fastening corresponding parts. The case set detachment structure includes a connecting board, a detachment rod, and an oblique stand. The connecting board is located on the first case and includes a moving part. The detachment rod includes a rod part, a moving corresponding part, and an oblique plate. The moving corresponding part is located on the rod part and is movably connected to the moving part. The oblique plate is connected to the rod part, such that the oblique plate and the rod part form an angle. The oblique stand is located on the second case and corresponds to the detachment rod, which includes an oblique surface.
