Abstract:
A system and method are provided for retrofitting a fluorescent lighting system, for example a passenger cabin fluorescent lighting system on a vehicle such as an aircraft. The present system may include at least one LED lighting unit for replacing, in situ, at least one fluorescent light of the fluorescent lighting system, and a control module for replacing, in situ, at least one ballast-type unit of the fluorescent lighting system that illuminates the at least one fluorescent light. The present system may further include a master control module, which may replace, in situ, an inverter of the fluorescent lighting system. The present method may include steps of: replacing at least one fluorescent light, in situ, with at least one LED lighting unit; and replacing at least one ballast-type unit, in situ, with at least one control module configured to control illumination of the LED lighting unit.
Abstract:
A lighting fixture for providing illumination comprising a housing, a printed circuit board, and a plurality LEDs connected to the printed circuit board. Optionally an emergency LED may also be included. A heat sink is connected to the housing and printed circuit board. Each of the plurality of the LEDs is mounted on the heat sink. A reflector is disposed inside the housing such that the light from the LEDs is mixed together and projected out of the illumination end of the housing by the surface of the reflector. The lighting fixture is received into a mounting flange assembly. A method for providing illumination using the above.

Abstract:
The invention provides a light module (1) with a light source (2) for emitting a beam of light (5), an adjustable optical element (300) for adjusting the beam of light (5) from the light source (2) into an adjusted beam of light (25) with a scattering pattern that is electrically variable; and a controller (304) for controlling, in response to an adjusting control signal (371), at least one element of a group of elements comprising the adjustable optical element (300) and the light source (2) by means of at least one driving signal (375, 376). A multi-purpose light, for example for interior car lighting, is advantageously provided thereby.

Abstract:
Interior architectural structures and lighting for aircraft, particularly- commercial passenger airplanes. Light diff users (140, 142) and ceiling panels in a "wing-shape" and other secondary panels (72, 74) are utilized to create different interior designs and structures. A permeable secondary panel is utilized in one passenger cabin in order to provide a more private-type space. An enlarged ceiling arch with blended curves forming a "wing- type" configuration provides a more spacious cabin arrangement (70, 72, 74). Other features include air and light diff users (102, 104), passenger service modules (64), a "shelf-like configuration and lighting above the airplane entrance/exit door (150) , and bulkheads and monuments positioned at various positions in the cabin (e.g. 152, 154).
Abstract:
A lighting system and method and apparatus for adjusting same are described. The lighting system has LED lighting units. To adjust a lighting unit, a programmer is connected to the lighting unit, lighting information (such as color or brightness) is input into the programmer (either manually or electronically), and data representing the lighting information is transmitted from the programming device to the lighting unit. The data is stored in the lighting unit, and one or more of the LEDs emits light that corresponds to the transmitted data.
Abstract:
Ceiling/luggage-rack combination for the passenger cabin of an aircraft with two longitudinal aisles consisting of a central luggage rack and two lateral luggage racks. The ceiling consists of individual curved ceiling elements which extend approximately between the upper edges of the luggage racks. The combination has tubular fluorescent lamps arranged in the longitudinal direction of the aircraft and associated with each ceiling element. The ceiling element (5, 11) is approximately paraboloidal; its region of smaller curvature extends as far as the fluorescent lamp (6). The fluorescent lamp (6) is covered by a shade (12) so that essentially indirect light enters the cabin. A reflector (7) arranged on the face of the fluorescent lamp (6) remote from the ceiling element (5, 11) reflects most of the light emitted by the fluorescent lamp (6) onto the ceiling element (5, 11). It is particularly advantageous that, as half the number of fluorescent lamps can be dispensed with, so can an equal number of pre-switching devices. This results not only in a reduction in manufacturing costs but also in a considerable reduction in weight.
Abstract:
An arrangement and method for providing an elongated light source, such as for illuminating a sign or other display, which includes emitting light from an exterior light source (4) into an inner tube (2) having a portion lined with a high reflectance film of prismatic lenses, the tube having a light-transmissive opening (14) along its length, with a diffusing medium (12) opposite such opening and optionally a reflector (6) at one end of the inner tube. The inner tube (2) is concentrically surrounded by an outer tube (3) having light-transmissive portions of different colors. The emitted light propagates in the inner tube (2) by reflecting from the high reflectance lining and the reflector to impinge on the diffusing medium and thereby transmit light outwardly through the light-transmissive opening and thereafter through a selected one of the colored portions.
