Abstract: Example embodiments relate to systems and methods for driving and controlling light sources. One embodiment includes a luminaire system. The luminaire system includes a support that includes a plurality of first light sources and a plurality of second light sources. The luminaire system also includes one or more first optical elements associated with the plurality of first light sources. Further, the luminaire system includes one or more second optical elements associated with the plurality of second light sources. Additionally, the luminaire system includes a drive and control means configured to drive and control the plurality of first light sources according to a first profile and the plurality of second light sources according to a second profile different from the first profile. The first profile defines a first drive output as a function of time and the second profile defines a second drive output as a function of time.

Abstract: Luminaire assembly comprising: a light source (100), a support (200) for carrying the light source, a protector (300) for protecting the light source (100) from external environmental influences, the protector (300) having an open top (310) for accommodating the support (200), a bottom (320) facing the light source (100) and a peripheral wall (330) between the open top (310) and the bottom (320). The peripheral wall comprises a transparent or translucent portion. The light source is configured to send light in use through said portion of the peripheral wall. The protector is provided with a light absorbing surface arranged inside of the protector and facing the light source. The light absorbing surface is configured such that in use part of the light emitted from the light source is absorbed by the light absorbing surface to reduce upward light pollution.

Abstract: Example embodiments relate to luminaire assemblies with reduced light pollution. One embodiment includes a luminaire assembly that includes a light source. The luminaire assembly also includes a support for carrying the light source.
