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.

The (LED or-and Laser) light source for bulb or light device such as garden light that has at least one of or more than one optics-lens, and light device has one top cover having shape of flat or ½ ball, ⅔ ball, sphere, dome shape for top cover. Foe laser light source incorporate with flat top protective lens and laser film or grating film to enlarge or created plurality of image, lighted patterns. For LED light source can has project assembly which is a built-in or add-on or assembled inside of said light device. Further can incorporated flexible bendable arms to change position, direction, orientation of (LED or-and Laser) light beam. The said Light device also can offer near-by and far-away illumination, or-and lighted image, pattern projection with desired light effects by rotating optic-lens or LED(s). It also can get desired effects while LED(s) controlled by IC or circuitry making LED(s) for color changing or on-off on desired time, duration, cycles. The light device further can have more than one function selected from USB charger, power failure, RF remote control, Infra-red controller, blue-tooth, wifi, internet, App software, motion sensor and wireless with multiple-way communication. Also, light device may have rechargeable circuit, batteries or rechargeable battery, USB ports for the (LED or-and Laser)-bulb be charged or supply other device current.

A battery assembly for a lighting fixture is provided. The battery assembly includes a battery unit comprising a battery unit housing and a first set of conductive pins. The battery unit housing is configured to accommodate one or more batteries configured to power one or more light sources of the lighting fixture. The first set of conductive pins are in electrical communication with the batteries. The battery assembly includes a battery interface comprising a battery interface housing and a second set of conductive pins. The battery interface housing is configured to accommodate the battery unit housing. The second set of conductive pins are coupled to the light source(s) so that the batteries power the light source(s) when the first set of conductive pins contact the second set of conductive pins. In some implementations, the battery unit can be inserted into the battery interface while the lighting fixture is energized.

A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.

A lighting device equipped at all times in a vehicle, which can be used for camping and leisure and has a function of a safety warning light of the vehicle, according to the present invention, comprises: a rectangular-shaped fixing plate having a pair of first magnet members which are disposed horizontally; a “C”-shaped front insertion groove which is formed on the front surface of the fixing plate and is formed to be adjacent to the edges of the fixing plate excluding the upper or lower edge of the fixing plate; a “C”-shaped first support member which is selectively fixed to the front insertion groove and is installed rotatably toward the front surface with respect to the fixing plate by the medium of a hinge; a pair of side surface insertion grooves which are longitudinally formed on the respective sides of the fixing plate; a pair of second support members which are respectively coupled to the inside of the side surface insertion grooves by the medium of a hinge, and are unfolded in a direction opposite to the first support member; a light unit which has, on the rear surface thereof, a second magnet member coupled to the first magnet members, has a battery embedded therein, and has a lighting device on the front surface thereof; and a cover which is rotatably coupled to the light unit by the medium of a hinge so as to selectively cover the lighting device, wherein the lighting device may flicker when the lighting device is covered by the cover.

A stable base supports a handle portion of an emergency light. The stable base has a stand portion and a base portion, which are separated from each other. The stand portion is assembled about the handle portion of the light, and has two pivotable legs extending therefrom. The handle portion itself together with the base portion forms a third leg. The base portion is formed from an upper and a lower portion assembled with a connecting member. A plate is formed on the lower base portion. In a first configuration, the legs are generally transverse to an axis of the emergency light handle, to form a tripod-like support on approximately level ground. In a second configuration, the legs are disposed downwardly so as to be generally parallel to the axis of the handle portion, such that the tips of the legs are disposed downward and are adapted to be inserted into the ground to resist high winds and gusts. In a third configuration, the legs are raised upward such that the tips of the legs are disposed adjacent to the handle portion of the emergency light, and are adapted to be inserted into a container for storage or shipping.

An emergency lighting unit includes a housing. The housing includes a base having a first portion and a second portion. A lamp assembly is rotatably connected to the housing and positioned in the lower portion. A cover is provided over the lamp assembly.

A lighting fixture configured to expand and collapse, and methods for expanding and collapsing a light fixture are disclosed. Embodiments of the lighting fixture include a lighting fixture with a movable section that collapses into at least one cavity in a base housing for storage and shipment, and extends from the cavity for operation. In the collapsed configuration the lighting fixture fits into a smaller container than when the lighting fixture is in the expanded configuration. In some embodiments a locking member locks the movable section into its extended position and can be retracted by a user by manually disengaging the locking member. Accessories and extenders that can be attached to the lighting fixture can be stored in the one or more cavities into which the movable section is stowed in the collapsed configuration.
