    Abstract: A light sensor includes an optoelectronic device and a light guide element. The light guide element has a first light incident surface and a light exit surface, so as to allow an incident light to enter the light guide element from the first light incident surface and then exit to the optoelectronic device from the light exit surface; wherein at least one of the light incident surface and the light exit surface has a single curved surface.

    Abstract: An calibration kit includes a base, a combination of calibration parts, and a manipulation part. The combination of calibration parts is disposed on the base and includes a first calibration part and a second calibration part. The first calibration part has a first calibration surface. The second calibration part has a second calibration surface. The first calibration part and the second calibration part are relatively movable in a movement direction and are movable relative to the base. The manipulation part is movably or rotatably disposed on the base. The manipulation part is configured to be operable to drive the first calibration part and the second calibration part to move in the movement direction relative to the base, so that the combination of calibration parts forms a three-dimensional calibration surface configuration through the first calibration surface and the second calibration surface.

    Abstract: A projector includes a casing, a lens, a bracket, a support member, a first spacer and a first fixing member. The lens is connected to the casing. The bracket is connected to the casing and has a through hole formed thereon. The support member is inserted into the through hole and abuts against the lens. The first spacer is disposed on the support member and has a first curved surface and the first curved surface faces the through hole. The first fixing member is disposed on the support member and pushes the first spacer towards the bracket, such that the first curved surface contacts a periphery of the through hole.

    Abstract: An electronic device includes a casing, a circuit board, an electronic component and a fixing member. The casing includes a fixing pillar and at least one rib. The rib is connected to a periphery of the fixing pillar. The circuit board includes a through hole. The fixing pillar is disposed in the through hole. The circuit board abuts against a second top surface of the rib. A thickness of the circuit board is smaller than a height between a first top surface of the fixing pillar and the second top surface of the rib. The electronic component includes a first metal member. A first ground end of the first metal member is disposed on the first top surface of the fixing pillar. A gap exists between the first ground end and the circuit board. The fixing member fixes the first ground end to the fixing pillar.
