An integrated ceiling device includes integrated ceiling device including an electronic device housing, a heat dissipating structure, a light source, and a reflection/refraction assembly. An air gap is defined between the electronics housing and other components allowing ambient air to flow therethrough for cooling.

Method for controlling the light distribution of a traffic route luminaire (1) in a network of luminaires, which is preferably also organized as a mesh network. The luminaire has a luminaire head having a settable light module and a controller, the light distribution of the luminaire being variable. The luminaire communicates luminaire data to at least one server, the luminaire data being luminaire-specific and including the installation location of the luminaire. The method comprises the steps of: —automatically allocating a light distribution to the luminaire (1) in accordance with the communicated luminaire data; —automatically setting the light module on the basis of the allocated light distribution; and determining, by said at least one server, a light distribution class of the traffic route luminaire on the basis of a traffic route topology (2,3,4,5,6).

Various examples related to automatic light control for illumination of a feature of interest are presented. A lighting system can automatically track a feature of interest, and/or a target positioned in relation to a feature of interest, and position one or more light sources to maintain illumination of the feature of interest. The location of the target, or the feature of interest, can be tracked using images captured by an image capture device and the orientation of one or more light sources can be adjusted to direct beams of light at the feature of interest. The beams of light can produce substantially shadow free illumination of the feature of interest. The controller can automatically calibrate a light source based on identifiable features within a captured image to ensure accurate movement of the light sources when tracking the target or feature of interest in or near real time.

A thin aspect lighting system and method are shown. The system and method include at least one module having a reflector that is generally elliptical in one cross-section and generally parabolic in another cross-section. Each module is adapted to generate at least one of a flat beam pattern, a high beam pattern or a low beam pattern, such as a low beam pattern with a kink or elbow. Also shown is a headlamp assembly having a plurality of modules that generate the same or a different light beam pattern. Manipulation and variation of facets or positions of various components, such as at least one light source provides improved characteristics in one or more of the light beam patterns.
