Various embodiments of the disclosure relate to a heat radiating structure and an electronic device including the same. According to various embodiments of the disclosure, it is possible to provide an electronic device including: a housing including a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a third surface enclosing an internal space between the first surface and the second surface, wherein at least one portion of the third surface faces a third direction different from the first direction and the second direction, wherein a first opening is formed in the first surface, and a second opening is formed in the third surface; a substrate disposed in the internal space; an electronic component disposed on at least one surface of the substrate; and a mesh member disposed in the internal space and disposed adjacent to the first opening and the second opening.

A headset includes a thermal frame disposed within a housing. A printed circuit board is thermally coupled to the thermal frame. Heat generated by one or more electrical components on the PCB is transmitted to the thermal frame, which distributes the heat uniformly throughout the headset. The thermal frame provides a substantially rigid structural support to which components are coupled and is configured to transfer thermal energy away from the one or more electrical components of the headset and toward an environment located outside of the housing.

A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.

An imaging apparatus is mounted on a moving object and configured to capture an image while moving along a moving direction of the moving object. The imaging apparatus includes a sensor unit including a sensor substrate on which an image sensor is mounted, and a main unit including a main substrate on which an electronic component configured to process an output signal from the sensor substrate is mounted. The imaging apparatus further includes a heat dissipation fin configured to dissipate heat generated in at least one of the sensor unit and the main unit. The heat dissipation fin is provided in a direction substantially parallel to the moving direction.

A vehicular camera includes a PCB having an imager disposed thereat, a lens barrel accommodating a lens, and a lens barrel support structure that protrudes from the PCB and at least partially circumscribes the imager. The lens barrel has an outer surface between the ends of the lens barrel. The outer surface of the lens barrel is adhesively bonded to an inner surface of the lens barrel support structure via adhesive. The outer surface of the lens barrel opposes the inner surface of the lens barrel support structure. With the adhesive in its uncured state and contacting the opposed surfaces, the imager is aligned with the lens accommodated at the lens barrel. With the imager aligned with the lens, the adhesive is cured to adhesively attach the lens barrel at the lens barrel support structure.

It is provided a lens unit to be small-sized, while reducing deterioration in optical performance after experiencing thermal expansion. The lens unit includes an aperture member, a lens, an image sensor, and a holder. A range where the aperture member abuts on a flange part of the lens overlaps with a range where the holder abuts on the flange part of the lens. A first gap is provided between a holder inclined surface of the holder and a lens inclined surface of the lens over the entire circumference. A second gap is provided between an outer circumferential surface of the lens and an inner surface of the holder over the entire circumference.

A mirror unit includes a light scanning device and a package. The package has a main body portion provided with a light incident opening that opens on one side in a predetermined direction, a protrusion provided on a top surface of the main body portion, and a flat plate-shaped window member disposed on the top surface on an inward side of the protrusion and covering the light incident opening. An end surface of the protrusion on the one side is positioned more to the one side than the window member. A thickness of the protrusion is smaller than a height of the protrusion from the top surface. When viewed in any direction perpendicular to the predetermined direction, a length of a part covered by the protrusion in the window member is longer than a length of a part exposed from the protrusion in the window member.

A fluorescent color wheel includes a substrate, a phosphor layer, and a fan blade structure. The substrate has a front surface, a rear surface opposite to the front surface, and a plurality of through holes communicating the front surface and the rear surface. The phosphor layer is disposed on the front surface. The fan blade structure includes a heat-dissipating plate and a plurality of first fan blades. The heat-dissipating plate has a first surface attached to the rear surface of the substrate. The first fan blades are disposed on the first surface and respectively pass through the through holes to protrude out from the front surface of the substrate.

According to at least one aspect, the present disclosure provides a head-up display device comprising: a housing having a receiving space therein; a display unit disposed over the housing; a light source unit disposed so that a main optical axis is not directed at the display unit; a first reflector reflecting at least some of light emitted from the light source unit towards the display unit; and a diffuser disposed on an optical path of the light source unit reflected from the first reflector to uniformly make light.

A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein thermal expansion or contraction of the optical element with respect to at least one of the detector or the base bends each flexure of the two or more flexures in a respective second direction without bending the flexure in a respective third direction approximately perpendicular to the first direction and the respective second direction, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.
