The invention provides a lighting module for use in a reflector which comprises at least one first light source emitting first light having a first light distribution with a first main direction and at least one second light source emitting second light having a second light distribution with a second main direction opposite to the first main direction. A base connects the lighting module to a luminaire socket. The base has a longitudinal axis extending from the base. The first light source is positioned on the longitudinal axis and the second light source is positioned at a non-zero distance to the longitudinal axis. The first main direction and the second main direction are substantially perpendicular with respect to the longitudinal axis.

Lighting module and a luminaire

An elongated lighting device () having a first and a second suspension point (') for suspending the lighting device (), comprising: a plastic housing () extending from the first suspension point () to the second suspension point (&#x2032;); a light source carrier () having one or more solid state light sources () mounted on a surface thereof, the carrier () being arranged along the housing () so that the one or more light sources () emit light into the housing (). A wire () is arranged inside the housing () between the first and second suspension points (&#x2032;) so as to prevent the lighting device () from bending.

Elongated lighting device based on solid state lighting technology

A lighting device is disclosed. The lighting device comprises a light transmitting housing and a solid state light source carrier () arranged inside the housing. The carrier () includes a cylindrical support (), which has two polygon base surfaces () and a number of side surfaces (), and a flexible circuit strip () which has several solid state light sources () mounted thereon. The strip () is wrapped around the cylindrical support () so that the strip () extends at least once across each base surface (). A method for producing a lighting device is also disclosed.

A light unit () is disclosed including a plurality of lighting devices (), in particular a plurality of LEDs, for emitting light. The light unit comprises connection terminals () for connecting the light unit to an external power supply () and for receiving an input voltage (V) and/or an input current (I) from the external power supply. A first current path () and a second current path () are connected to the connection terminals each comprising at least one lighting device, wherein the first current path and the second current path are connected in parallel to each other. The second current path has a controllable resistor () for controlling an electrical current Iin the second current path and a current limiter () for limiting the current in the second current path. The light unit comprises a control unit () adapted to control the controllable resistor on the basis of the electrical current in the second current path and on the basis of an electrical current (I) in the first current path or a total current (I) in both current paths.

Light unit for emitting light and method for driving a light unit

According to an embodiment of the present inventive concept there is provided an arrangementcomprising: an optical deviceincluding a radially inner beam forming portionand a radially outer portion, at least partly enclosing the radially inner portion. The arrangementfurther comprises a reflectorarranged to reflect, in a first direction towards the radially outer portion, light emitted by a light sourcesuch that a first optical path is formed from the light sourceto the radially outer portion, via the reflector. The radially outer portionis transparent such that incident light reaching the radially outer portionalong the first optical path exits the radially outer portionin a direction parallel to the first direction, and at least one of scattering and attenuating for light reaching the radially outer portionalong a second optical path extending directly between the light sourceand the radially outer portion. The radially outer portionmay thus act as a clear exit window for reflected light R, contributing to the intensity of a central beam F formed by the radially inner beam forming portion, while preventing transmission of direct light D which otherwise could produce glare.
