  • linear lights For the illumination of indoor and outdoor spaces nowadays often longitudinal lights are used, which extend along a space or an object on which they are arranged. Such lights are commonly referred to as linear lights and can for example be mounted directly on walls, suspended or mounted on ceilings or attached to it.
  • linear lights typically include a straight or curved generally elongated or longitudinal base profile which is attached directly or indirectly to the object or wall or ceiling.
  • linear lights usually have a light bar, along which a series of bulbs such as LED bulbs and associated control gear are attached.
  • a primary optics is often used, which covers the bulbs so that the light emitted by the bulbs light has preferred radiation characteristics.
  • primary optics determine the hue, scatter and / or direction of the emitted light.
  • Linear lights are typically completed by an at least partially transparent cover or an outer diffuser as secondary optics, which surrounds at least the areas of the luminaire, which are not facing the wall or the ceiling.
