An optical structure for controlling distribution of light generated by a light source is described. The optical structure includes a primary optics disposed relative to the light source and configured to reflect light generated by the light source towards a target region. The optical structure also includes a secondary optics disposed and aligned relative to the primary optics. The secondary optics is configured to at least partially block light generated by the light source from illuminating a region outside the target region.

A daylighting system (10) to be installed over an interior face (1001a) of a window pane (1001), the daylighting system (10) including: a light-transmitting device (20) to be disposed over an upper part of the interior face (1001a) of the window pane (1001); and a shading device (30) joined to the light-transmitting device (20) in such a manner as to be disposed over a lower part of the interior face (1001a) of the window pane (1001).

There is a category of situations which may have previously been considered direct replacement but in fact takes on many elements of a true retrofit; namely, replacing existing LED lighting systems (which they themselves were retrofits) with different LED lighting systems that (i) overcome a deficiency or inadequacy of the existing LED lighting system retrofit, (ii) adds a functionality to the existing LED lighting system retrofit, or (iii) reestablishes functionality that would otherwise be lost with the existing LED lighting system retrofit. Discussed herein are means to provide improved glare control, horizontal beam containment, playability and control functionality for interfacing with third party controls in these so-called retrofit-of-a-retrofit, or upgrade situations.

A light control device includes: a sheet-like light control member; and a support device supporting the light control member such that an orientation of the light control member is variable. The light control member includes: first portions arranged in a first direction along a sheet plane of the light control member, each first portion extending in a second direction that is in non-parallel with the first direction and along the sheet plane of the light control member; and second portions arranged in the first direction alternately with the first portions, each second portion extending in the second direction.

A daylighting device according to an aspect of the present invention includes a daylighting member and a support unit, disposed on an interior side of a window glass to support the daylighting member. The support unit includes an adjusting mechanism that adjusts a position of the daylighting member relative to the window glass.
