An apparatus, system and method for controlling airflow is described. The apparatus comprises a wall which delimits a flared bore. The apparatus further comprises at least one air guide member which retractably protrudes into the flared bore from the wall. The flared bore widens to an outlet, thereby to permit a diverging airflow to be expelled therefrom when each of the at least one air guide member is retracted. When the at least one air guide member protrudes into the flared bore, air flowing in the flared bore is guided by a surface, e.g. a concave surface, of the respective air guide member away from the wall and towards the outlet. The retractable air guide member thus enables the direction and/or degree of convergence of the air flowing out of the outlet to be controlled.

Apparatus, system and method for controlling airflow

The invention provides a lighting device, comprising a light exit chamber (), delimited by a light exit body (), a plurality of light sources (), positioned within the light exit chamber (), and arranged to emit light in the direction of the light exit body (), an optical processing element, adapted to process the light emitted from the plurality of light sources (), and a transparent antenna element (), extending into the light exit chamber () and positioned relative to the plurality of light sources () such that each light source is arranged to transmit light toward the antenna element, wherein said transparent antenna element () is separate from the optical processing elements, wherein the transparent antenna element () being transparent for the light emitted by the plurality of light sources (), and the antenna element () comprises: a transparent conductive material that is self-supporting.
