  • Patent number: 11680690
    Abstract: The invention relates to a light fixture (100) having: an elongate light source, which is formed by multiple LEDs (60) or LED clusters arranged one behind the other in the longitudinal direction; a primary optical system (20), which is assigned to the light source and is formed by multiple pot-like reflectors (25), which are arranged one behind the other in the longitudinal direction and each widen in a divergent manner from the light source in a light emission direction of the light fixture (100); and a secondary optical system (30), which follows the primary optical system (20) in the light emission direction and is formed by a planar element consisting of a transparent material, wherein the element has light-refractive structures (35).

  • Patent number: 11391443
    Abstract: The lamp component includes a light orienting element having a light incident end, a light output end opposite the light incident end, and a side surface extending between the light incident and light output ends; and a housing configured to position the light orienting element adjacent a light source. The housing is at least partially translucent, and includes at least one sidewall and a main wall facing the light output end. The light orienting element is configured to deflect a fraction of the incident light towards the light output surface to be projected through the main wall as to direct light, and a fraction of the light towards the at least one housing sidewall to be projected as indirect light. The light orienting element is a first part formed by extrusion in a first direction, and the housing is a second part formed by extrusion in a first direction.

  • Publication number: 20210332968
    Abstract: The lamp component (1) has: a source region (2) to receive a LED light source (10), a light output surface (4) to output light, a light orienting element (6) to orient the received light towards the light output surface (4), and a housing to position the light orienting element (6) with respect to the source region (2), with a housing sidewall to let light pass through it. The light orienting element (6) i) deflects a fraction of the light towards the light output surface (4) so as to produce direct light, and ii) it refracts a fraction of the light towards the at least one housing sidewall so as to produce indirect light. The light orienting element (6) is formed by a first extruded part extending in an extrusion direction. The housing is formed by a second extruded part extending in the extrusion direction.

  • Publication number: 20150354806
    Abstract: In a hospital supply device with an elongated, substantially horizontally extending supply housing with a connector for an electrical power supply and/or for the provision of technical gases. At least one a patient reading light is arranged on an underside of the supply housing. The patient reading light is formed by a number of light modules arranged next to one another in the longitudinal direction of the supply housing, of which a subgroup corresponding to the desired position of the reading light can be activated in a reading light mode.
