| 20140254185 | Railcar Shove Light - A railcar shove light for attachment to a railcar rear coupler, the railcar shove light incorporating a turbine; a turbine case having a compressed air input port and an air output port, the turbine being rotatably mounted within the turbine case; an electrical alternator; a rotary drive linkage interconnecting the turbine and the electrical alternator; an array of electrical light emitters; electrical wires interconnecting the electrical light emitters and the electrical alternator; a light case housing the turbine, the turbine case, the alternator, the drive linkage, and the light emitter; and incorporating a brake line connectable air conduit for supplying and driving the turbine; the light case being mounted to a support post having lower end coupler engaging pin. | 09-11-2014 |
| 20150078019 | LIGHT STRIP FOR A PASSENGER COMPARTMENT OF A RAIL VEHICLE - A light strip, lighting fixture or lamp band for installation in an interior passenger compartment of a rail vehicle includes a plurality of elongate light covers that can be connected to each other in the longitudinal direction thereof to form the light strip. A double-walled intermediate cover is provided between at least two successive light covers in the longitudinal direction of the light strip. The inner wall of the light strip protrudes opposite the outer wall in the longitudinal direction of the light strip so that a gap resulting between the intermediate cover and the adjacent light cover is concealed. | 03-19-2015 |
| 20150138788 | OPTICAL MEMBER AND LIGHTING DEVICE USING THE SAME - Provided are an optical member capable of implementing optical images having a desired shape and a lighting device using the optical member. The optical member can include a base substrate and a plurality of unit patterns sequentially arranged on a first surface of the base substrate and each having an inclined surface with respect to the first surface. Each unit pattern can be extended in a pattern extension direction, respectively. The plurality of unit patterns and the inclined surfaces thereof can be structurally arranged on the first surface of the base substrate such that any beam of incident light that strikes a unit pattern at a right angle to the pattern extension direction in which said unit pattern extends is guided away from the optical member. | 05-21-2015 |
| 20160025293 | LED LIGHTING ASSEMBLY FOR A SCHOOL BUS LAMP - An LED lighting assembly for a school bus lamp has a reflector and an LED module. The reflector has a base, a reflecting wing, and a connector. The reflecting wing is formed around the base. The connector is formed on the base. The LED module is mounted on the reflector and has at least one LED. The LED lighting assembly can be mounted on the seat of the school bus lamp by the connector and is covered with the lampshade of the school bus lamp. The LED lighting assembly can be directly mounted on the seat of the school bus lamp for reducing the replacement cost, and a lighting element of the school bus lamp is replaced by the LED lighting assembly. So the LED lighting assembly is suitable for the seat and the lampshade of the school bus lamps. | 01-28-2016 |

| 20090021955 | CONTROL NETWORK FOR LED-BASED LIGHTING SYSTEM IN A TRANSIT VEHICLE - A transit vehicle lighting system has a plurality of LED-based lighting fixtures for providing interior illumination. A control network comprises a plurality of slave nodes for controlling the LED-based lighting fixtures, and a master node for controlling the slave nodes. The master node may be connected to the slave nodes by a combined power/communication bus in a daisy chain fashion. The slave node may include a power regulator and a controller for providing a target current command to the power regulator, and may adjust the target current based upon temperature measurements or a recorded age of the LEDs. An optical sensor may provide automatic dimming. A reduced number of LEDs may be used in an emergency mode. The lighting fixture may include a ceiling panel fixture and a riser panel attachable by way of a hinge mechanism. | 01-22-2009 |
| 20090237950 | LOW GLARE LIGHTING FOR A TRANSIT VEHICLE - A low glare overhead lighting fixture for a transit vehicle comprises a lighting fixture base assembly for mounting one or more light sources (e.g., LEDs or fluorescent tubes), and a light permeable cover adapted to reduce glare. The light permeable cover may include a light guide embodied as a grid-like structure with holes or perforations for directing the light from the light source in a manner reducing light spread. The light guide may be disposed between a front and rear lens covers. The lighting fixture may also utilize a light permeable cover having an anti-glare surface element, such as a privacy filter screen or mesh which may be formed using microlouver technology. The lighting fixture base assembly may have separate compartments, each lined with a highly reflective coating, housing one or more deeply set LEDs. | 09-24-2009 |
