The disclosed embodiments generally relate to extruding multiple layers of micro- to nano-polymer layers in a tubular shape. In particular, the aspects of the disclosed embodiments are directed to a method for producing a Bragg reflector comprising co-extrusion of micro- to nano-polymer layers in a tubular shape.

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.

Disclosed is a photosensitive resin composition for an optical waveguide containing a resin component and a photoacid generator. In the photosensitive resin composition, the resin component is constituted of an epoxy resin component containing both an aromatic epoxy resin and an aliphatic epoxy resin, and the content of the aromatic epoxy resin is 55 wt. % or more and less than 80 wt. % of the entirety of the epoxy resin component and the content of the aliphatic epoxy resin is more than 20 wt. % and 45 wt. % or less of the entirety of the epoxy resin component. Accordingly, for example, when a core layer of an optical waveguide is formed using the disclosed photosensitive resin composition for an optical waveguide, a core layer of an optical waveguide having satisfactorily low tackiness and high transparency while maintaining satisfactory roll-to-roll compatibility and a high resolution patterning property can be formed.

A lighting assembly is provided that includes a light fixture in combination with a support grid such as a drop ceiling t-bar. The light fixture can be configured to use a t-bar as the main form of support. The light fixture can be push-fit onto a t-bar or use a clip to join two or more portions of the light fixture to an installed t-bar. Once attached to the T-bar, the light fixture itself can provides support for a ceiling tile. Various embodiments are provided which achieve a variety of light distributions useful in typical illumination applications. Both recessed and suspended fixture types are achieved in various embodiments which are particularly well suited for LED lighting.
