The present invention relates to a lighting device (). The lighting device comprises a light source () arranged at a base () of the lighting device, the light source having a main forward emission direction (). The lighting device further comprises a radio frequency, RF, antenna () configured to receive signals for controlling the lighting device and a reflector () arranged to reflect light from the light source laterally and backwardly. The RF antenna is arranged at the reflector. The present invention is advantageous in that the RF reception of the lighting device is improved.

Lighting device with RF antenna

There is provided a lighting devicecomprising a light source, a driver arranged for powering the light source, which is separated in space from the light source. The lighting device has two separate heat sinks, a light source heat sinkto which the light source is thermally coupled, and a driver heat sinkto which the driver is thermally coupled. The light source heat sink and the driver heat sink are separated by an air gapto provide thermal decoupling of the light source heat sink and the driver heat sink.

Lighting device

A lighting device () for providing a homogeneous luminous intensity distribution in relation to an optical axis of the lighting device (), the lighting device () comprising: at least one light source (); a housing () arranged to enclose the at least one light source (), the housing () comprising an at least partly transparent housing portion being arranged in parallel to the optical axis of the lighting device (); and a reflector () arranged inside the housing (), the housing () and the reflector () together defining a single light mixing chamber (), wherein the reflector () is arranged to reflect light from the at least one light source () away from the optical axis of the lighting device () towards the at least partly transparent housing portion.

Single chamber lighting device

This invention relates to a lighting device having a light source (), a light output unit, a drive unit () arranged to drive the light source, an electrical connection unit connected with the drive unit and arranged to receive input power, and a heat sink (), which has been provided with multiple reception portions (). At least the light source and the drive unit are mounted at a first respectively a second reception portion of the heat sink. The heat sink is a formed sheet structure, which has been formed into a predetermined shape from a sheet shaped heat sink blank.
