The present invention relates to a light guide device for the introduction of sunlight into the interior of a building, having a multitude of movably mounted light deflection surfaces which are adjustable by control means depending on the position of the sun. According to the present invention the light deflecting surfaces of the light guide device are formed by serially arranged deflecting blades which may be swiveled about swivel axes which are approximately parallel to each other, the blades being mounted on a blade holder which is rotatable about a rotational axis which is essentially perpendicular to the direction of the swivel axes.

Light guiding device

An operating lamp includes at least one white light source for illuminating an operating area, a plurality of colored light sources for illuminating the operating area, and a controller adapted for dimming a light intensity and controlling a spectrum of a combined illumination from the white light source and the colored light sources on the operating area.

Operating table lamp

A lighting apparatus including a number of light modules oriented to illuminate a work site, an array of individually controllable lights disposed on each of the light modules, and a lighting controller configured to individually control the lights disposed on the light modules to selectively define concentric illumination zones.

Multiple module lamp

A luminaire for an elongate lamp has longitudinal reflectors running parallel to the lamp and a multiplicity of spaced-apart transverse lamellae. The lamellae have a bottom, tapering region with a bottom edge that is curved. The cross-section of the bottom, tapering region is of the same shape over the width of the transverse lamellae. The edges of the bottom tapering region have the same curvature, with the lower edge coinciding with the bottom edge of the transverse lamellae.
