An imaging device includes an imaging element that receives subject light, a lens that directs, to the imaging element, the subject light from an imaging range having a predetermined angle of view in at least a first direction, an illuminator including a light source that emits illumination light toward the imaging range and a cover covering the light source, and a housing including a top plate on a plane intersecting with an optical axis of the lens and a bottom surface facing the top plate. The housing accommodates the imaging element and the illuminator. The predetermined angle of view includes a direction from the lens toward the bottom surface in an area of the predetermined angle of view in at least one direction with respect to the optical axis of the lens. The top plate includes a slope with an inclination corresponding to the predetermined angle of view. The cover in the illuminator is parallel to the slope.

Inspection assemblies that include one or more sideview cameras for capturing images of an interior surface of a pipe or conduit include an elongate housing, a sideview camera within the housing and arranged to capture an image of a region within a field of view external to the housing, and a viewport element mounted in the housing and located such that light is transmitted through the viewport element and into said sideview camera, wherein the viewport element has a concave internal surface, closer to the camera, and a convex external surface, further from the camera, and wherein the centre of the radius of curvature of the internal surface is closer to the viewport element than the centre of the radius of curvature of the external surface.

A light source module comprising: a light source having an upper surface comprising a light emission surface; and a light guide member including a lens portion having a central axis that extends through a center of the light emission surface. The lens portion includes: an incidence surface, a reflection surface, and an emitting surface. The incidence surface comprises an upper incidence region positioned on an upper side, and a lower incidence region positioned lower than the upper incidence region, in a cross section that includes the central axis. The lower incidence region has 2-fold rotational symmetry. The lower incidence region includes a first lower incidence region, and a second lower incidence region at a position rotated by 45 degrees from the first lower incidence region. A height of the second lower incidence region is greater than a height of the first lower incidence region.

Camera head apparatus, systems, and methods for providing wide angle/panoramic images and/or video of the interior of pipes or other cavities using multiple imaging and illumination modules are disclosed.

A connecting system for lighting members includes a rotary hinge assembly with an internal electrical connection, an upper hinge portion, a lower hinge portion, a central axial bolt that resides within an axial channel in the upper hinge portion and the lower hinge portion; and at least one LED strip assembly with a translucent LED module cover, a LED module of at least one LED in an array, a strip frame and at least one end cap with a female electrical connection port. A method for assembling a connecting system for lighting members includes connecting a first LED strip assembly with a rotary hinge; connecting a second LED strip assembly with the rotary hinge; placing a mount on one of the LED frames and engaging the mount with a support device; and inserting a power cord into a power connection port and connecting the power cord to a power source.

A light source module includes: a light source having an upper surface comprising a light emission surface; and a light-guide member comprising a lens portion having a central axis. The lens portion includes: a concave incidence surface facing the light emission surface of the light source; a reflection surface disposed outside the incidence surface, the reflection surface being configurd to reflect part of light entering through the incidence surface, and being inclined at an angle of 45 degrees or more from a direction perpendicular to the central axis; and exit surface. The incidence surface includes: a first incidence area having four-fold symmetry about the central axis and having a curved concave shape in a cross section containing the central axis; and a second incidence area having a curved convex shape in a cross section rotated 45 degrees from the first incidence area and containing the central axis.

A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emittting diode (LED) is mounted on a printed circuit board (PCB), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.
