A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source; the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.

A lighting device including: a light guide, a reflecting sheet and a first prism sheet, in which a first white LED, a second white LED and a third white LED are disposed in a same interval on a first side surface and on a second side surface, which opposes to the first side surface, a first prism array extending in a first direction and arranged in a second direction is formed on the major surface, a second prism array extending in a second direction and arranged in a first direction is formed on the back surface, the reflecting sheet is disposed under the back surface of the light guide, the first prism sheet is disposed on the major surface of the light guide, and a third prism array, extending in the second direction and arranged in the first direction is formed on the back surface of the first prism sheet.

A mini-LED backlight structure and a backlight module are provided. The mini-LED backlight structure includes a backplate, a glass substrate, and reflective sheets. The glass substrate includes a line surface and a lineless surface close to a side of the backplate. Light emitting diodes and a connector are disposed on the lineless surface. Furthermore, a gap is between the backplate and the glass substrate for disposing the light emitting diodes and the connector. The connector is electrically connected to an external circuit through a conducting wire. Disposing a plurality of elements, the connector, and the light emitting diodes on a same surface of the lineless surface is unlikely affecting backlight effect and saves materials at a same time.

An extended field-of-view near-to-eye display system provides for AR/MR image viewing over about a 180° FOV. The display system may include a multiplicity of display panels per eye of a user and may include both high- and low-resolution display capabilities. The high-resolution displays may be positioned in front of the user's eyes in their primary visual field while the low-resolution displays may be positioned so as to be seen by the user's peripheral vision. The low-resolution displays provide cueing information to the user out to the limit of visual perception (for each eye), placing encoded light and movement in the periphery of the user's vision for enhanced situational awareness.
