The present disclosure relates generally to light management constructions comprising microstructured prismatic elements useful in the preparation of sun-facing light redirecting films having reduced glare.

A light transmissive substrate for transforming a Lambertian light distribution into a batwing light distribution. The light transmissive substrate includes a first surface comprising a plurality of microstructures, and a second surface on a side of the substrate opposite the first surface. The substrate is configured to receive light in a Lambertian distribution from a light source at the first surface and transform the light into a batwing distribution exiting the second surface. The batwing distribution having a peak intensity at about ±30° to about ±60° from X and Y axes, and a minimum intensity at nadir.

A lighting device assembly includes a light source attached to a heat sink member, a first optic device and a mounting housing configured to be secured in or to a ceiling, wall or other object, and to hold the heat sink member. A second optic device including a second optic member is configured to receive light emitted in a first direction from the light emitting surface of the first optic device and to emit light in a second direction that is transverse to the first direction. A connection mechanism selectively connects the second optic device to the mounting housing, for selective disconnection from the mounting housing.

The present disclosure provides decorative lights using prismatic film such as Optical Lighting Film (OLF) available from 3M Company, and a diffuse partial reflector. The decorative lights generate design styles and comfort for a light fixture, and can use solid state lighting such as Light Emitting Diodes (LEDs) to generate the light. The decorative lights can have an appearance that changes with the viewing angle of the light.

Techniques disclosed herein relate to micro light emitting diodes (micro-LEDs) for a display system. A display system includes an array of micro light emitting diodes (micro-LEDs), an array of output couplers optically coupled to the array of micro-LEDs and configured to extract light emitted by respective micro-LEDs in the array of micro-LEDs, a waveguide display, and display optics configured to couple the light emitted by the array of micro-LEDs and extracted by the array of output couplers into the waveguide display. Each output coupler in the array of output couplers is configured to direct a chief ray of the light emitted by a respective micro-LED in the array of micro-LEDs to a different respective direction.

A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

A light distribution device includes a light transmissive substrate having first and second opposing faces and a plurality of substantially parallel linear prisms on the second face that extend in a longitudinal direction of the substrate. The light distribution device is configured to connect to a light assembly including a linear light source with the first face of the substrate facing the light source, with the linear prisms substantially parallel to a light source longitudinal axis and with and the substrate having a non-planar cross-sectional shape such that at least a major portion of the substrate is concave relative to the light source. When connected, the light distribution device is configured to receive light from the light source and distribute the light emerging from the second face of the substrate in a batwing distribution pattern in a plane perpendicular to the light source longitudinal axis.

The present disclosure discloses a projection lamp. The projection lamp includes a light-emitting assembly including at least one first non-coherent light source, a light-reflection medium, a first condensing lens, a driving device, a driving gear, and a driven gear. An inner wall surface of the light-reflection medium is formed by mutually connecting a plurality of irregular light reflection surfaces; the first non-coherent light source is arranged in the light-reflection medium; the first condensing lens is arranged above the light-reflection medium; the driving gear is connected to the driving device; and the driven gear is arranged on the light-reflection medium and is engaged with the driving gear to drive the light-reflection medium to rotate. The technical solution of the present disclosure effectively improves the diversity of the light effect of the projection lamp.

Disclosed are a lamp for an automobile and an automobile. The lamp for an automobile includes a micro lens array (MLA) module which is provided in front of a light source and into which light is incident. The MLA module includes a light-incident lens array and a light-emitting lens array. At least a portion of optical axes of a plurality of light-incident lenses provided in a first section of the light-incident lens array is aligned with one of optical axes of a plurality of light-emitting lenses provided in an A section of the light-emitting lens array. At least a portion of optical axes of a plurality of light-incident lenses provided in a second section of the light-incident lens array is misaligned with all of the optical axes of a plurality of light-emitting lenses provided in a B section of the light-emitting lens array.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.
