Disclosed herein are various embodiments related generally to computer vision, graphics, image scanning, and image processing as well as associated mechanical, electrical and electronic hardware, computer software and systems, and wired and wireless network communications to form at least three-dimensional models or images of objects and environments.

A complex device that integrates a beam shaping aperture in a printed circuit board of the complex device (e.g., scanner or barcode reader or optical module) is provided. The complex device has a light-emitting diode pattern projection system. The pattern projection system includes one or more light-emitting diodes and a printed circuit board. The printed circuit board has one or more apertures and one or more receptacles. The one or more receptacles are positioned behind the aperture and receive the one or more light-emitting diodes. The printed circuit board with receptacle offer self-alignment for the light emitting diodes. The beam shaping aperture in front of the light-emitting diodes allows light to pass through the aperture that is part of the printed circuit board layer of the complex device.

A vehicle visual element includes a substrate defining a lamp cavity; at least one light source positioned within the lamp cavity; at least one of a holographic and a diffraction grating, disposed over the lamp cavity; a proximity switch positioned close to the lamp cavity; and a controller configured to activate the light source in response to a signal provided by the proximity switch.

A pointer includes a case housing an LED device and including a light emission hole through which light from the device is emitted to an external space, a first plate between the device and the light emission hole and including a first light passage hole that allows passage of the light from the device, and a second plate between the first plate and the light emission hole and including a second light passage hole that allows passage of the light having passed through the first light passage hole. The light passage holes and the light emission hole are located on a central axis of the device. The device and the first and second plates are disposed such that H/2<S<H, where H denotes a distance between the device and the first plate, and S denotes a distance between the first and second plates.

Methods and apparatus are presented for retaining a dome lens in a lighting element that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting elements includes a dome lens that is removably positioned proximal to a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.

A shield for a lighting fixture includes a panel that is optically transparent and a screen attached to the panel. The screen has opaque segments, where the opaque segments have gaps therebetween. The screen is screen printed onto the panel. The opaque segments are distributed on the panel in a pattern.

A luminaire system is provided that has directional light projection optics combined with a light distribution modifier to produce a non-uniform angular light intensity distribution from a single or array of light sources. The luminaire system provides for light intensity distribution with directional asymmetry meeting the specifications and requirements of aviation obstruction lights. The light distribution modifier component or subassembly redirects, scatters, refracts, diffracts and/or blocks part of the projection light in the distribution of the primary optics that would otherwise produce ground scatter. Unlike peripheral light shields at the marginal limits of the light distribution from the luminaire light system, the light distribution modifier is located near to the optical axis of the projection optics system.
