Abstract: 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.

Abstract: A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

Abstract: A light fixture usable in train tunnels provides normal mode downlighting for track and walkway lighting and a selective task lighting mode where higher-lumen lighting is provided in at least the same downlighting direction as the track and walkway lighting. The normal lighting illumination level is at least 0.25 to 2.00 foot-candles at the illuminated surfaces. The task lighting mode provides at least 5.00 foot-candles to the same illuminated surfaces. The task lighting mode is achieved with the same light source that provides the normal mode lighting or with additional light sources that are activated together with or instead of the normal lighting mode light sources. The light sources can be a plurality light emitting diode (LED) engines that include a plurality of LEDs. The task lighting mode can also use another light source to provide additional task lighting up from the fixture.

Abstract: A light fixture and wireway assembly is provided in a low-profile configuration wherein at least a portion of a plurality of wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine. In one configuration, at least portions of two to four individual wireways are disposed in a stacked configuration with a low-profile, edge-lit LED light engine powered by an LED power supply also disposed within the outer perimeter of the overall assembly. Each wireway can be accessed through a single wireway wall without requiring conduit outside of the outer perimeter of the assembly.

Abstract: 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.

Abstract: LED lighting systems, mounting configurations, and light fixtures are disclosed for original and retrofit configurations. Some configurations mount the light fixture with a mounting bracket that allows for the removal and replacement of the light fixture in about the same time as a traditional light bulb change. Some configurations provide for fuse removal and replacement without the need to dismount the light fixture from its mounting bracket or without the need to open the housing of the light fixture to access the fuses. Some configurations use a battery backup system and self-check methods with LED light fixtures configured for public transportation applications.

Abstract: The disclosure provides an LED light system that is easy to install and customizable by the user. The LED lighting system may be plugged directly into an existing power source. In one configuration, the system includes a power supply that accepts standard power inputs. A low voltage bus line extends from the power supply. The user may connect LED light modules at essentially any location along a low voltage bus line of the system so that the light modules are located exactly where the user desires light. Uneven spacing is possible. Different size lights, different lumen powers, and different-colored light modules may be disposed along the low voltage bus line. Security features may be used to reduce the value of the system components to a thief.

Abstract: Controlled environment light fixture configurations include an LED light source. The light fixtures can be installed and removed from below the ceiling. The light fixture can be installed and removed without opening the lens frame of the light fixture. The light fixture includes a sealed housing and seals to the ceiling when installed. The light fixtures are provided in exterior dimension sizes that allow the fixtures to be installed in a variety of controlled environment ceilings in recessed configurations. The lower surface exposed to the controlled environment is free of welds and grinds in order to provide a corrosion resistant surface.
