A lighting system has a set of linear lighting elements and a set of suspension elements. Each suspension element comprises an upper fixing part and a lower connection part facing downwardly for making electrical and mechanical connection to an upward facing connector on a top face of an end of a linear lighting element. This enables a simple a push fit connection of the lighting elements to the suspension elements, after they have been suspended from a support structure above them.

Lighting system, lighting installation and ceiling installation

Disclosed is a luminaire () comprising: a heatsink () comprising a rim () 5 having a first rim section (), a second rim section () and an intermediate rim section () in between the first rim section and the second rim section; a first heatsink region comprising a mounting region () and a plurality of first fins () extending from the mounting region to at least one of the first rim section and the second rim section; and a second heatsink region comprising a plurality of second fins () looping from the 10 intermediate rim section; a light module () mounted in the mounting region () and thermally coupled to the first heatsink region, the light module comprising at least one light engine () and a controller () for the at least one light engine; and a sensor () mounted on the second heatsink region, the sensor being communicatively coupled to the controller, the controller being adapted to control the at least one light engine in 15 response to a sensor signal from the sensor.

Heatsink and luminaire

A lighting device including a glass tube; a solid state lighting assembly in said glass tube, said assembly including an electrically insulating optical film having at least one arcuate portion lining a part of the inner surface of the glass tube, wherein the glass tube includes a further part defining a light exit portion; and a plurality of solid state lighting elements on a carrier, said carrier contacting said optical film; a thermally conductive member in between at least a part of the solid state lighting assembly and the glass tube for thermally coupling the solid state lighting elements to the glass tube; and a transparent or translucent electrically insulating cover contacting the electrically insulating optical film and covering the solid state lighting elements. A luminaire including such a lighting device and a lighting device assembly method are also disclosed.

Lighting device, luminaire and lighting device assembly method

A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.
