摘要： An optical construction includes an optical film between first and second prismatic films, which each include pluralities of parallel, linear first and second prisms. Each of the first and second prisms have opposing first and second sides extending from first and second ends of a base of the prism and meeting at a peak. The first and second sides make first and second base angles with the base of the prism. The peaks of the prismatic films face away from each other and the optical film. For a collimated, normally incident light, for at least a first wavelength in a first wavelength range, and for each of first and second polarization states: the optical film has an optical transmission of less than about 1%, and the optical construction transmits at least 1% of the incident light at an oblique angle greater than 5 degrees with respect to the optical film.

摘要： A planar illumination device of an embodiment includes a plurality of light sources, a substrate, and a reflector. The light sources are bidimensionally disposed on the substrate. The reflector is provided with a segment including a hole corresponding to each of the light sources and a reflecting surface extending obliquely from a periphery of the hole, is provided with outer walls at an entire outer peripheral portion of the reflector, and is disposed at an emission side of the substrate. In the segment disposed at an irregular portion of an outer peripheral portion of the reflector and unconfigurable into a predetermined shape by the outer walls, surfaces of the outer walls opposing the substrate are provided with recessed portions for accommodating the light sources or adjusting the amount of light.

摘要： A light module projects multiple light beams onto an installation surface to form multiple light indicia spaced apart in a pattern on the installation surface, with the light indicia identifying installation locations on the installation surface where construction mounts are then installed. Embodiments include systems in which the light module includes a light emitter that projects a source light beam and a diffractor that diffuses the source light beam into the multiple light beams, systems in which the light module is adjustably mounted to and movable with a handheld tool used to install the construction mounts, systems in which the light module is adjustably mounted to a static-use support, and methods of using these systems to install the construction mounts.

摘要： A portable lighting apparatus is provided with a gallium-and-nitrogen containing laser diode based white light source combined with an infrared illumination source which are driven by drivers disposed in a printed circuit board assembly enclosed in a compact housing and powered by a portable power supply therein. The portable lighting apparatus includes a first wavelength converter configured to output a white-color emission and an infrared emission. A beam shaper may be configured to direct the white-color emission and the infrared emission to a front aperture of a compact housing of the portable lighting apparatus. An optical transmitting unit is configured to project or transmit a directional light beam of the white light emission and/or the infrared emission for illuminating a target of interest, transmitting a pulsed sensing signal or modulated data signal generated by the drivers therein. In some configurations, detectors are included for depth sensing and visible/infrared light communications.
