Abstract: The present invention relates to a luminaire comprising one or more LED light sources (102) arranged within a light chamber that is enclosed by a translucent cover (302), having an inner surface (308), wherein the LED light source (102) is arranged to illuminate the inner surface (308) of the translucent cover (302). The translucent cover (302) comprises a prismatic optical structure (304) on the inner surface (308) for reflecting and/or refracting light from the LED light source (102) omni-directionally. The prismatic optical structure (304) is designed such that a direct view of the LED light source from outside the luminaire is obstructed by means of total internal reflection at the prismatic optical structure.

Abstract: A connector assembly comprising at least a first connector body provided with a first mechanical interconnection element and a first connector part having at least one first conductor. The connector assembly further comprises a second connector body provided with a second mechanical interconnection element, a housing and a second connector part having at least one second conductor. The first and second connector bodies are releaseably connectable to each other by means of the mechanical interconnection elements, whilst the first and second conductors are releaseably connectable to each other. The second connector part is mounted on a slider being slideable with respect to the housing along a longitudinal axis thereof. The slider is slideable against spring force from a first position, wherein the slider is located near a front end of the second connector body to a second position at a distance of the front end.

Abstract: A non-transparent light-emitting construction element (100; 200; 300; 400), comprising: a construction element having a mounting side and a user-facing side (104; 204; 304) to be facing a user when the light-emitting construction element is used in a construction; and a light-emitter (108; 404) embedded in the construction element, wherein the light-emitter is embedded in the construction element in such a way that the light-emitter is non-visible in its off-state and light from the light-emitter escapes from the construction element when the light-emitter is in its on-state
