The present disclosure relates to a lighting apparatus. A lighting apparatus according to an embodiment of the present disclosure includes: a dome structure including a first opening opened in a circular or polygonal shape at least partially in one surface thereof, and a second opening opened in a circular or polygonal shape at least partially in the other surface so as to be larger than the first opening; a plurality of reflective plates configured to connect one line the first opening and one line of the second opening; a PCB provided in the dome structure and disposed at a predetermined first angle based on a region of the other surface that excludes the second opening in the other surface of the dome structure; and a light source disposed on the PCB, in which light outputted at the first angle from the inside of the dome structure through the light source is reflected through at least one of the plurality of reflective plates, and the reflected light is emitted through the second opening to an object disposed at a lower end of the second opening and spaced apart from the dome structure.

Described herein are high intensity illumination systems including lighting arrays of lights, such as light emitting diodes, configured to illuminate a surface. The lighting arrays are configured to illuminate the surface with illumination comparable to or multiple times brighter than the ambient illumination, such as sunlight. Also described herein are methods of using a high intensity illumination system to illuminate a surface for applications including imaging, object detection, and object localization. The systems and methods described herein may be applied to a range of industries including farming, agriculture, construction, and autonomous vehicles.

An apparatus for inspection of IV bags includes a base having a working surface. A conveyor is raised above the working surface with conveyor supports and includes a plurality of bag clips, each adapted to hold one of the IV bags in an inverted position at one of a plurality of workstations. A controller moves the conveyor such that the bag clips each move from one workstation to the next at set intervals. A loading workstation places one of the IV bags into one of the bag clips. A bubble mitigation station agitates a fluid within the IV bag to dislodge any air bubbles. Two particle agitation stations agitate the fluid and any debris particles. An inspection station includes a backlighting apparatus, a camera, a display, and a rejection chute leading to a disposal receptacle. An unloading workstation unloads IV bags that have passed inspection.

A method to minimize applying joint compound and sanding by illuminating an area of the gypsum board to show anomalies thereon includes a step of providing a plurality of wireless lighting devices operable by a common remote controller, a step of removably attaching these devices in a spaced-apart arrangement and using the remote controller to energize all lighting devices to identify remaining anomalies. All lighting devices are turned off once the next coat of joint compound is applied and then turned on after it dries to illuminate the remaining surface anomalies. Operation of lighting devices is accomplished without removing or repositioning thereof to assure consistency of illumination over the entire work period.

An inspection system is described. The inspection system includes a camera and a housing. The housing contains a reflective dome. The reflective dome includes an apex and a viewport. The viewport is offset from the apex. The camera is mounted to capture light exiting the reflective dome through the viewport. And, a plurality of light sources are arranged about the reflective dome such that light output from the plurality of light sources enters the dome.

A fused imaging device and method are disclosed. The device comprises a light source component, an image capture component, and a control component. The control component may be configured to control the light source component to illuminate a target object based on a preset plurality of first optimal lighting configurations. The control component may further control the image capture component to capture images of the target object to obtain multiple first images, under the illumination of the light source component and generate a target image of the target object, based on the first images. The control component may further adjust the incidence angle, pattern, and wavelength of the light source in the light source component, as well as the exposure, lens focus, and polarization of the image capture component, to detect target object defects in captured images of the target object.

Accuracy of detecting abnormalities on the surface of a workpiece is improved. An appearance inspection apparatus for inspecting the appearance of a workpiece is provided. The appearance inspection apparatus for inspecting the appearance of the workpiece includes a first lighting unit that irradiates the workpiece with light, a first imaging unit that images the workpiece irradiated by the first lighting unit, a first detection unit that detects a first defect from an image captured by the first imaging unit, a second lighting unit that irradiates the workpiece with light, a second imaging unit that images the workpiece irradiated by the second lighting unit, and a second detection unit that detects a second defect from an image captured by the second imaging unit. The first lighting unit uses coaxial epi-illumination, and the second lighting unit uses coaxial epi-illumination and dome illumination.

Near InfraRed NIR technology, including NIR cameras and detectors, is used to accurately identify surface irregularities on a veneer surface. A grade is then assigned to the veneer based, at least in part, on the detected irregularities. In one embodiment, the veneer is then provided to an improved veneer stacking system that produces more consistently graded veneer stacks and safer veneer stacks, is less expensive to operate, and is far safer than currently available methods and systems for full veneer sheet, veneer strip, and partial veneer sheet stacking.
