Abstract:
A locomotive headlamp comprising one or more light emitting diode (“LED”) bulbs, wherein the headlamp is ideally suited for reducing the parasitic load of the locomotive by up to about 86 percent, and which is designed and installed in a locomotive's headlight housing to cause the heat generated by the one or more LED bulbs to prevent snow and ice impaction around the locomotive headlamp, and to prevent damage to the electronics and/or circuitry used to operate the one more LED bulbs from the locomotive's power source.
Abstract:
A device for controlling a lighting and/or signalling system of a vehicle that includes means adapted to determine a dew point temperature value inside the system from at least one value of the temperature inside the system and at least one value of the relative humidity inside the system.
Abstract:
A moisture removing lamp for a vehicle that autonomously generates electricity and may be charged with electricity by using a solenoid generator that uses vibration of the vehicle, thereby removing moisture in the lamp for a vehicle in an environmentally-friendly manner.
Abstract:
A headlamp of a vehicle is disclosed having an optical system arranged after a light source in a path of a light beam emitted by the light source. The light beam has a directed main beam and a component of undirected diffused light. A cover screen is arranged parallel to the directed main beam after the optical system. A plate for discharging heat is arranged after the cover screen. A lens cover in combination with the cover screen forms an in travelling direction front cover of the headlamp. The cover screen has an aperture which opens the space between the optical system and the cover screen in the direction of the plate and the optical system includes an optical lens body and the undirected diffused light of the light source substantially radiates through the aperture in the cover screen onto the plate.
Abstract:
The invention relates to a light guiding element (1) for a laser vehicle headlight (2), wherein the laser vehicle headlight (2) comprises at least one laser light source (3) and at least one luminous element (4) which can be irradiated by the laser light source (3) and can thus be excited to emit visible light. The light guiding element (1) has a first side (10), which is designed at least partly as a light entrance surface (5), and a second side (20) arranged opposite the first side (10), said second side being designed at least partly as a light exit surface (6) and being assigned at least one receptacle (7) for at least one luminous element (4), wherein the light entrance surface (5) is assigned at least one first reflection region (50) which is oriented in the direction of the interior of the light guiding element (1) and reflects light from the light entrance surface (5) in the direction of the receptacle (7) for the luminous element (4), and wherein the light exit surface (6) is assigned at least one second reflection region (60) which is oriented in the direction of the interior of the light guiding element (1) and reflects light from the luminous element (4) in the direction of the light exit surface (6). The invention furthermore relates to a vehicle headlight (2) comprising at least one light guiding element of this type.
Abstract:
A light retainer is provided with a grommet having a tubular body with an inner surface providing a cavity with a first inner groove and a second inner groove spaced lengthwise of the body from the first inner groove, the first inner groove configured to receive a heated lens and the second inner groove configured to receive a light. A heated light assembly is also provided with a grommet, a heated lens and a light.

Abstract:
A headlamp assembly for a vehicle, comprising: a housing for coupling the headlamp assembly to a vehicle, the housing including an inner surface defined by a reflector; a planar heat sink structure having a first surface, a second surface, a housing abutting edge and a substantially straight edge, the housing abutting edge being adapted to abut an inner surface of the housing, wherein the heat sink structure is adapted to separate the housing into first and second sections; a circuit board supported by the second surface of the heat sink structure, the circuit board being positioned near the substantially straight edge of the heat sink structure; a first light emitting diode being supported by the first surface of the heat sink structure and being electrically connected to the circuit board, the first light emitting diode lying in substantially the same plane as the first surface of the heat sink, and a second light emitting diode being supported by the second surface of the heat sink structure and being electrically connected to the circuit board, the second light emitting diode being positioned between the housing abutting edge of the heat sink structure and the circuit board, wherein the circuit board and the second light emitting diode each lie in substantially the same plane as the second surface of the heat sink structure and do not overlap.
Abstract:
Anti-icing solid state aircraft lamps are disclosed. The anti-icing solid state aircraft lamp includes at least one solid state light source, a substantially optically transparent cover optically coupled to the at least one solid state light source, and at least one defroster element coupled to the optically transparent cover.
Abstract:
In a light chamber formed in a housing case and a lens cover placed at a front part of the housing case in a headlamp assembly, a projection lens, a shade and a light source are arranged in line from the front side of the light chamber along an optical axis of the light source. A radiating member has radiating fins of a plate shape vertically placed in the light chamber, and radiates heat energy generated by the light source to surrounding air. A slit composed of a vertical slit part and an inclined-slit part is formed in each of the radiating fins. The formation of the slit generates a change of heat capacity and a temperature difference at upper and bottom parts of each of the radiating fins. The incline-slit part is extended from the top of the vertical slit part to the upper part of the radiating fin.
