Abstract: A heat dissipation structure adapted to dissipate heat from a heat generating component includes a central housing and a first wing housing. The central housing includes a top portion and a bottom portion opposite to each other, an internal space located between the top portion and the bottom portion, and a first opening communicating with the internal space. The top portion includes multiple through holes. The bottom portion is connected to the heat generating component. The first wing housing is connected to the central housing and includes a first entrance distant from the central housing and communicating with the first opening. The first entrance has a dimension larger than the first opening. An air flow sequentially flows through the first entrance, the first opening, and the internal space and flows out from the through holes.

Abstract: An electronic device includes a housing, a dual-metal assembly, and a baffle. The housing has a through hole. The baffle is movably disposed in the housing. The baffle has at least one opening. The dual-metal assembly is connected to a side of the baffle and includes a first metal and a second metal. A thermal expansion coefficient of the first metal is different from a thermal expansion coefficient of the second metal, so that the dual-metal assembly is adapted to change between an initial state and a deforming state. When the dual-metal assembly is in the initial state, the opening is distant from the through hole. When the dual-metal assembly is in the deforming state, the dual-metal assembly drives the baffle to move, so that at least a portion of the opening is communicable with the through hole.

Abstract: A quick-release positioning member, including a fixing portion, a first elastic portion, and a second elastic portion, is provided. The fixing portion is adapted to fix the quick-release positioning member to an object. The first elastic portion is connected to a first side of the fixing portion, extends toward a first direction, and has a first bending area protruding away from the fixing portion. The second elastic portion is connected to a second side of the fixing portion, extends toward a second direction, and has a second blocking area protruding toward the fixing portion. The first and second elastic portions are adapted to be deformed upon exertion of force. The first elastic portion is adapted to move in a third direction. The second elastic portion is adapted to move in the second direction. The first, second, and third directions are substantially orthogonal. An openable and closable device is also provided.

Abstract: A lamp device includes a controller, a plurality of light-emitting elements, a plurality of current conversion modules and an interpretation module. The controller is configured to output a dimming signal. The current conversion modules are coupled to the light-emitting elements and configured to control the light-emitting elements to emit light. The interpretation module is coupled to the current conversion modules and configured to output, according to a comparison table, a plurality of control signals corresponding to the dimming signal to the current conversion modules respectively. The light-emitting elements are different in a luminous property, and one of the current conversion modules is configured to output a feedback signal to the controller.

Abstract: A light distribution module configured to control a light distribution of a light source is provided. The light distribution module includes a lens and an optical cover. The lens has a first light-incident surface, a first light-emitting surface opposite to the first light-incident surface, and an accommodating recess located at a side of the first light-incident surface, wherein the accommodating recess is configured to contain the light source. The optical cover covers the lens and has a second light-incident surface and a second light-emitting surface opposite to the second light-incident surface, wherein the second light-incident surface is located between the first light-emitting surface and the second light-emitting surface, and the second light-incident surface has a plurality of sub-curved surfaces. Boundaries between adjacent sub-curved surfaces are bent-shaped with respect to the adjacent sub-curved surfaces.
