A railing assembly includes a bottom rail and a top rail extending parallel thereto and spaced apart therefrom. Both rails include a beam defining through-holes and corresponding pocket-holes located opposite from the other rail to define ledges facing away from the other rail. A plurality of balusters of light-transmissive material each extend between the bottom rail and the top rail, through a corresponding through-hole and pocket-hole in each railing. Retaining rings are disposed around each of the balusters within each of the pocket-holes for engaging the ledges and thereby holding the balusters to each rail. Each rail may include a plate of light-transmissive material extending in a plane adjacent the beam and configured to project light along a length thereof. One or more illumination sources are disposed in the top rail and/or the bottom rail to direct light into the balusters and/or the plate(s) to provide options for multiple illumination effects.

Provided is an illumination device comprising a support structure and a light-emitting component being provided on one side of the support structure. The support structure also has an opening on one of its sides and an optical component cooperating with the opening to form an accommodating space. The illumination device also comprises an integrally formed light transmission portion provided above a light-emitting side of the light-emitting component. The light transmission portion is configured to transmit light from the light-emitting component. The illumination device additionally comprises a plurality of sealing portions being integrally formed.

A system and method for reducing bird collisions with glazing utilizes a UV light source and a perforated opaque object. The UV light source is located adjacent an edge of a glass panel and is configured to project UV light rays onto a planar surface of the glass panel. The perforated opaque object is located between the UV light source and the planar surface of the glass panel, such that UV light rays passing through the perforated object cast onto the planar surface of the glass panel a UV shadow visible to birds and substantially invisible to humans.

A light fixture for a public transportation train system powers an antenna used for train signaling. The antenna can provide to the train a location marker associated with the location of the antenna. The antenna can provide to the train other data communicated to the light fixture through the light fixture communication system.
