Surface-mounted or wall-mounted luminaire

Abstract

The invention relates to an elongate light fixture having a substantially triangular cross-section. The light fixture is screwed to a supply duct with the rear wall thereof. A front rail runs parallel to the rear wall. Transparent panels and are inserted detachably between the rear wall and rail. In the interior of the light fixture, a fluorescent lamp is provided as the luminous element. The light emitted by said fluorescent lamp is reflected upward by way of reflector surfaces that open in the shape of a funnel and is scattered diffusely in the direction A by means of the frosted panel. The panel surfaces, which likewise open in the shape of a funnel, reflect the light exiting downward from the lamp in the direction toward the panel, the grooved structure of which ensures that the light is deflected substantially in the direction B, while the portion of the side light exiting in the direction C is reduced. With this reflector and panel configuration, firstly good illumination of the space and secondly specific and glare-free workplace lighting is made possible.
