A lighting fixture for providing illumination comprising a housing, a printed circuit board, and a plurality LEDs connected to the printed circuit board. Optionally an emergency LED may also be included. A heat sink is connected to the housing and printed circuit board. Each of the plurality of the LEDs is mounted on the heat sink. A reflector is disposed inside the housing such that the light from the LEDs is mixed together and projected out of the illumination end of the housing by the surface of the reflector. The lighting fixture is received into a mounting flange assembly. A method for providing illumination using the above.

In its broadest concept, the present invention relates to an improved gear oil comprising: a) a base oil having a viscosity range of 4 to 32 cSt at 100 DEG C; b) a maximum level of hydrocarbyl polysulfide with a minimum level of active S species; c) a dihydrocarbyl dithiophosphate ester or salt; and d) a dihydrocarbyl (mono)thiophosphate amine salt, essentially free of phosphite.

Escape path marking for aircraft, which has an afterglowing photoluminescing material which is placed in several elements on the floor, characterised in that at least one element has a bent shape.

The invention relates to an illumination apparatus having at least a first and a second illumination unit, wherein each of the illumination units comprises an LED arrangement and a supply device for supplying the LED arrangement, each of the LED arrangements comprising at least one LED group having a multiplicity of LEDs and the LED groups of the LED arrangements being similar, and having a control device for driving the at least two illumination units with a common nominal dim drive value, the nominal dim drive value driving the illumination units in such a way that the similar LED groups of the illumination units are operated in a dim mode. The invention also relates to a method for operating the illumination apparatus in the dim mode.

A kind of illuminating device (1) which forms with the medial top liners (2) of the vehicle separately, and is suitable to provide illumination for the passenger seat area (3) inner the vehicle.

An interior aircraft LED light unit includes at least one LED and a lens cover arranged over the at least one LED, the lens cover having a proximal side facing towards the at least one LED and a distal side forming an outside portion of the interior aircraft LED light unit, with the lens cover being made from a lens cover material exhibiting material-specific light transfer properties. The lens cover comprises a pattern of dots on the distal side, with each of the pattern of dots locally altering the material-specific light transfer properties of the lens cover.

The invention relates to escape path markings for aircraft and to an assembly consisting of an escape path marking and a floor fitting. The escape path marking (1) for aircraft comprises a lighting element (3), which luminesces in the dark and the emitted light of which exits on an outer face (2) of the escape path marking (1), and a transparent protective element (5) arranged between the lightingelement (3) and the outer face (2) of the escape path marking (1). A flat grid element (6) which comprises regularly alternating pure color-transparent and opaque regions (7, 8) is provided between the lighting element (1) and the outer face (2) of the escape path marking (1). A transparent colored element is formed and arranged between the lighting element (3) and the outer face (2) of the escape path marking (1) such that a specified first hue is produced on the transparent regions (7) of the grid element (6) in the event of external lighting according to at least one specified lighting scenario on the outer face (2) of the escape path marking (1). The assembly (10) comprises an escape path marking (1) and a floor fitting (11) arranged adjacently to the escape path marking (1). The escape path marking (1) according to the invention is designed such that a pattern which is adapted to the pattern of the floor fitting (11) is produced when the assembly (10) is externally lit accordingto at least one specified lighting scenario on the outer face (2) of the escape path marking (1).

A lighting system for an emergency exit from an occupied space: an array of lighting elements located around the emergency exit to illuminate the exit and facilitate egress for an occupant of the space; a control unit; and sensors to detect one or more trigger conditions and actuate the lighting elements in response to a first trigger condition from any of the sensors, the sensors comprising: an impulse detector operable to send a signal to the control unit indicating that the impulse detector has experienced an impulse; and a roll and / or pitch detector operable to send a signal to the control unit indicating that the roll and / or pitch detector has experienced roll and / or pitch, wherein upon detection of the first trigger condition the control unit actuates one or more of the lighting elements to illuminate the exit.

A rail vehicle emergency lighting system for a rail vehicle includes a main lighting system with light emitting diodes. When a main lighting power supply is active, the light emitting diodes of the main lighting system are lit with a main lighting intensity. When the main lighting power supply fails, the light emitting diodes of the main lighting system are lit with an emergency lighting intensity. The emergency lighting intensity is reduced compared to the main lighting intensity.

Emergency cabin illumination for an aircraft, including: at least one cabin component of an aircraft and at least one emergency lighting device, the at least one emergency lighting device being arranged in the cabin component so that the emergency lighting device in its switched-off state has no contrast to its environment, and in the switched-on state of the emergency lighting device, the light emitted emerges from the cabin component.
