Abstract: Disclosed is a light (1) comprising means (3a) for retaining and electrically connecting at least one elongate light source (2) and a light-influencing element (10) which is located next to the light source (2) and is composed of several individual elements (15). Said elements (15) that form the light-influencing element (10) can be swiveled or rotated independently of each other about an axis that extends substantially parallel to the longitudinal axis of the light source (2).

Abstract: The invention concerns a luminaire having a housing, which at the emission side of the luminaire has a housing opening, having, situated in the housing, connection means for at least one lamp which define the position thereof in the housing, having a light guiding element which is so positioned that, in the main emission direction, it is located in front of the lamp to be used, and having at least one diffuser arranged at the side neighbouring the light guiding element, which has a shaping projecting beyond the edge of the housing, having a flank rising towards the light guiding element. In order to improve the light guiding and/or light emission of the diffuser, the shaping has further a flank falling towards the light guiding element.
