摘要： A resiliently flexible, rubberized light housing for sealingly enclosing and protecting a light bulb or fixture against moisture and other intrusion. The housing has an elongated, generally tubular body with an open first end and a closed second end. The open first end may receive and retain a bulb or fixture that has an exposed bulb or element or is environmentally sealed. If the bulb or fixture is sealed, then the same may hermetically seal the open first end. If the bulb or fixture is not sealed, then a lens may be included to hermetically seal the open first end with the bulb or fixture in the interior. Electrical wires for connection to the bulb or fixture may be passed through a sealing port on the closed send end. The plurality of ribs are configured for friction contact with the inside of a lighting can.

摘要： Gobo projection targeting devices have a light source, a lens assembly associated with the light source, the lens assembly having a first element, a second element, and an aiming figure, the first element being closer to the light source, and the second element having a smaller diameter than the first element, such that a first portion of light emitted by the light source and transmitted by the first element will bypass the second element and a second portion of light emitted by the light source and transmitted by the first element will not bypass the second element. The first and second elements may each be converging lenses. The second element may be adapted to generate an image of the aiming figure away from the illuminator. The first portion of light may be a field illumination pattern lacking a focused image. The lens assembly may be movable.

摘要： An optical element for use in front of a light source 102 for obtaining a skylight appearance, and a luminaire are provided. The optical element comprising a plurality of light transmitting cells in a raster structure 140, a diffuser 145 and an edge wall 130. A light source 102 emits light towards the raster structure 140. The raster structure 140 collimates a part of the light and transmits a further part of the light in a predetermined spectral range. White light 114 and colored light 112 that is transmitted by the raster structure 140 may impinge upon the side wall 130 of the optical element. One face of the side wall 130 is a region of specular reflectivity 135 and will reflect the light that impinges upon it back into the chamber 125 that is formed by the cooperation of the raster structure 140, the diffuser 145 and the edge wall 130. Light exits the optical element through the diffuser 145. A weak diffusion of the diffusing layer 145 is advantageous to obtain a light emission distribution which has a smooth transition between light 114 which directly originates from the light source 102 and the colored light 112 that is transmitted through the walls of the light transmitting cells.
