摘要： A smart lamp system and method for monitoring a status of LEDs. The system can provide LED status monitoring using a logic controller communicating with at least one strip of LEDs. The system can utilize the logic controller to assign a unique identifier (ID) to the at least one strip of LEDs based on a physical position of a plurality of dual-inline package (DIP) switches incorporated within a smart lamp housing. The system can provide a hardware architecture to interface the logic controller with a power-line communication (PLC) transceiver. The system can establish a communication protocol between the PLC transceiver and a PLC receiver to efficiently communicate the statuses of the LEDs. The logic controller can generate a payload including a binary representation of the unique ID of the smart lamp and the statuses of the LEDs and transmit the payload to the PLC transceiver.

摘要： A signal light assembly is provided that comprises a multi-position Fresnel lens having a circumference, a first side and a second side. The signal light assembly further comprises a main housing configured to attach to the multi-position Fresnel lens. The multi-position Fresnel lens includes a first plurality of pads and a second plurality of pads on the first side of the multi-position Fresnel lens such that the first plurality of pads and the second plurality of pads are different and alternatively disposed. The first plurality of pads corresponds to a first range operation related to a first focal length. The second plurality of pads corresponds to a second range operation related to a second focal length. The multi-position Fresnel lens is disposed in a first position corresponding to the first range operation or in a second position corresponding to the second range operation based on the use of either the first plurality of pads or the second plurality of pads for assembly between the main housing and the multi-position Fresnel lens.

摘要： A lamp system (200) includes a lamp assembly (210, 215) with a light source (212) coupled to a base (214), an electronic circuit (216) for operating the light source (212), and a switching device (218) for setting a flash rate of the light source (212). A lamp communication device (250) configured to transmit control signals to the lamp assembly (210). A communication network (260) interfaces with the lamp assembly (210) and the lamp communication device (250). The electronic circuit (216) is configured to operate the light source (212) in response to a control signal (262) transmitted by the lamp communication device (250) via the communication network (260), and in accordance with a set flash rate so that the light source (212) switches between an on state and an off state by default.

摘要： A light signal, in particular for rail-bound traffic routes, includes a control device which controls a light source, and an optical system for visualizing a signal term. In order to more precisely adjust brightness boundaries, light distribution and phantom light intensity, a transmission-controllable smart-glass element is provided in an aperture segment of the light flow.

摘要： The sign pole system disclosed simplifies the FRA requirement by incorporating many features into the sign pole system. The worker operating the pole can quickly raise the pole just by stepping on the lift bar. To lower the pole ‘remove the required safety’ is done by stepping on the release footstep. The built in LED features will activate only when it is nighttime and when the pole is in the vertical position. The sensitivity to actuate the LED's is adjustable to compensate for night yard overhead lighting. A solar panel keeps the battery charged. When required a pad lock (lock out device) can be inserted into the foot step base to secure the sign pole system in the up position until deemed safe by the worker to remove the sign protection. Manually attaching a night time blue light is no longer required because the LED light is now built into the sign pole and is automatically actuated.

摘要： A lamp driver card to control lighting of a lamp load located on a wayside of a railway system is provided. The lamp driver card comprises a light source controller module including at least one channel having a semiconductor switch or a relay to receive power on a copper cable sized at a selected gauge size from a power source to turn ON or OFF the lamp load. The light source controller module is configured to support a multi-voltage rating range operation extended from a limited voltage to an extended operating voltage and a current rating to light the lamp load such that the light source controller module is compatible with relatively higher DC/AC voltages. The copper cable is sized at the selected gauge size of a first size to a second size based on a selected voltage rating of a first voltage system or a second multi-voltage ranges system.

摘要： A circuit arrangement for revealing light signal errors, in particular for railway safety systems, includes an electronic signal generator, which can be disconnected in a reversible manner in the event of an error, and a control part, configured for incandescent lamps, for controlling and monitoring the signal generator. The device for revealing errors includes an error differentiator between the line-related interference voltage and error of the signal generator. The reliability of the error differentiation is improved and rendered independent of capacitive intermediate energy storage devices, in that the signal generator is connected to a resistance arrangement such that the signal generator voltage is greater, in high-resistance signal generators, than an interference voltage.
