The present invention relates to a lighting device (), comprising: at least one light source () adapted to emit light (b); a uniform diffuser () forming a light exit window of the lighting device; and a non-uniform volumetric diffuser () arranged between the at least one light source and the uniform diffuser.

Lighting device having a non-uniform volumetric diffuser with open and/or closed cells

An illumination device () provided with a support structure (), an array of a plurality of spatially separated solid state lighting elements () mounted on a first side of the support structure (), as well as an optical element () made from a light diffusing material for diffusing light emitted by the array of the plurality of spatially separated solid state lighting elements (), the optical element () being mounted on the first side of the support structure and provided with a pattern formed of an array of a plurality of recessed portions () and an array of a plurality of elevated portions ().

Illumination device, optical element and luminaire

A device for determining a type of a power source for powering a LED lighting unit, wherein one possible type comprises a ballast originally designed for a high intensity discharge lamp and repurposed for use with an LED lighting unit. The power source type determiner monitors at least one electrical parameter of either a load or the power source itself after a power drawn by the load whose characteristic is set to a critical value. A value of the electrical parameter is used to identify a type of the power source. A value of the electrical parameter is the pulse generated by the traditional ballast for gas discharge lamp, which pulse is detected to determine the type of the power source.

Power source type determiner

The invention provides a lighting module () for use in a luminaire (). The lighting module comprises a base () having a longitudinal axis (LA) which comprises an electrical connector () for connecting the lighting module () to a luminaire socket () of the luminaire (). The lighting module () further comprises a driver unit () which comprises a driver circuit () which is electrically connected to the electrical connector (). The lighting module () further comprises a light unit () which comprises at least one solid state light source () which is electrically connected to the driver circuit () and emits light. The lighting module () further comprises a heat sink () which removes heat from the at least one solid state light source (). The heat sink () comprises an elongated hollow tube () which extends in the direction of the longitudinal axis (LA) and comprises a fluid inlet () and a fluid outlet (), wherein the heat sink () is arranged between the driver unit () and the light unit ().

Lighting module and a luminaire comprising the lighting modulespe

A lighting module () for connecting to a luminaire, the lighting module extending along a longitudinal axis (LA) and comprising: a base () for connecting the lighting module () to a socket () of the luminaire (); a central body () carrying at least a first light source () and a second light source (), wherein the first light source () is configured to emit first light having a first light distribution with a first main direction pointing away from the longitudinal axis (LA), and the second light source () is configured to emit second light having a second light distribution with a second main direction pointing away from the longitudinal axis (LA), the first and second main directions being different from one another; and an optical element () including at least one optical portion () and a cover portion () extending all around the central body () and said optical element () being rotatable about the longitudinal axis (LA) in relation to the central body (), the at least one optical portion () having an optical property, such that the optical portion () is configured to affect light emitted from at least one of the light sources, the at least one optical portion () extends in an angular area around the longitudinal axis (LA), and the cover portion () is configured not to affect light emitted from the remaining sources.

Lighting module

A lighting module () for use in a luminaire, comprising a heat sink () for dissipating thermal energy, which heat sink () is polygonal in cross section, forming a number of surfaces () corresponding to the polygonal shape of the heat sink (), each surface () extending in a longitudinal direction, said longitudinal direction extending substantially perpendicularly to a plane of said cross section, each surface () having a centre line () extending in said longitudinal direction, at least two LEDs () being located on each of at least three of said surfaces (), wherein all of the LEDs () on a first () of said at least three surfaces () defines an accumulated light emitting area of said first surface (), which accumulated light emitting area is distributed asymmetrically in relation to the centre line () of said first surface ().

The invention provides a lighting module () for use in a luminaire (). The lighting module () comprises: a base () having a longitudinal axis (LA) and being constructed for rotatably connecting the base () to a socket () of a luminaire (). The lighting module () further comprises a carrier () connected to the base () and extending from the base () in the direction of the longitudinal axis (LA). The lightingmodule () further comprises a light unit () comprising a light source () and a heat sink () for dissipating thermal energy of the light source (). The heat sink () extends in the direction of the longitudinal axis (LA) and is positioned at a non-zero distance Dto the longitudinal axis (LA). The lighting module () further comprising a connecting construction () connecting the light unit () rotatably to the carrier () for rotatingthe light unit () both around the carrier () and longitudinal axis (LA).
