A light fixture includes a lamp having a light source, a petal mechanism having a plurality of petals moveable between an open position and a closed position, and a petal actuator coupled to the petal mechanism to controllably move the petals of the petal mechanism between the open position and the closed position.

The present invention concerns a lamp (1) having a number of plates (3, 4, 5). The plates (3, 4, 5) are moveable between a position where the plates (3, 4, 5) form a common outer surface and a position where the plates (3, 4, 5) are separated from each other. By means of the plates the shape and appearance of the lamp (1) may be amended between having the form of for instance a closed sphere and a more or less open form. The plates (3, 4, 5) are placed on upper and lower curved arms (17, 26). The curved arms (17, 26) are connected to an upper ring (10) and a lower ring (9). The curved arms (17, 26) are moved by movement of the lower ring (9) towards and away from the upper ring (10).

A lamp shade is provided for covering a light source. The lamp shade has a hoodlike base body which is open at least at the bottom and at least partly transparent, which is placed over the light source and covers it. The base body can have on its outer surface at least one encircling indentation, in which a decorative ring is adapted to be fitted and braced there.

Light fixtures (100, 200, 400, 500, 600, 700) are provided, including a lighting element (10, 20, 40, 50, 60, 70), an oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72) disposed adjacent to or connected to the lighting element, and a control mechanism (14, 24, 44, 64, 74). The control mechanism is in electrical communication with the lighting element (10, 20, 40, 50, 60, 70) and controls an energy output of the lighting element and a temperature of the oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72). Typically, when the control mechanism changes the temperature of the oriented crosslinked semi-crystalline polymer, the shape of the polymer changes. A method of making a light fixture (100, 200, 400, 500, 600, 700) is also provided. The method includes providing a lighting element (10, 20, 40, 50, 60, 70), forming a crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72), and disposing the crosslinked semi-crystalline polymer adjacent to the lighting element (10, 20, 40, 50, 60, 70) or connecting the crosslinked semi-crystalline polymer to the lighting element. The method further includes electrically connecting a control mechanism (14, 24, 44, 64, 74) with the lighting element.

A light unit used in train tunnels is readily mountable and removable from a mounting bracket. The mounting bracket allows the battery backup system and light engine to be gravity mounted in manner that allows for quick and easy mounting and removal while also resisting vibrations and wind. A quick disconnect fitting can be used with the power cord to allow the units to be removed and replaced as needed. The light unit integrates the light engine with a battery backup system so that the entire light and battery unit is removed and replaced when necessary.

A leveling system for a lamp shade can include a bearing, a stud extension, and a weight. The bearing can be positionable around a stud of a lamp shade assembly and can be configured to be supported by a bracket of the lamp shade assembly. The bearing can define a bearing surface engageable with a hub of the lamp shade to provide an articulation surface for the hub. The weight can be releasably securable to a spoke of the lamp shade and can be positionable on the spoke to level the lamp shade about the bearing with respect to a plane.
