Definitions

  • the invention relates to an elongated luminaire with built-in mirror optics for a rod-shaped lamp according to the preamble of claim 1.
  • Luminaires of this type are mostly referred to as wallwashers and have an extremely asymmetrical light distribution for uniform illumination of vertical surfaces such as walls, shelves and counters.
  • the luminaires must be mounted at a certain distance from the vertical surface in order to achieve uniform illumination. This optimal installation distance is set at a ratio of 1: 3 to the suspension height or wall height. Due to structural conditions or subsequent changes, this requirement can practically often not be met and therefore no ideal lighting conditions are achieved.
  • an electric lamp with a rod-shaped light source in which a partially movable reflector with variable light distribution is installed in a housing.
  • the reflector is formed from a cylindrical part which is fixed to the housing and surrounds the lamp approximately semicircularly and a flat leg which is articulated thereon.
  • the light is emitted either downwards or in an approximately horizontal direction. This does not result in an extremely obliquely radiating luminaire, but the light is emitted in the upper half-space.
  • a luminaire is known from DE-A 33 16000 in which an elongated light source faces a channel-shaped reflector arrangement which is open at the bottom.
  • This consists of a head mirror and two movable side mirrors, each of which can be adjusted around a swivel axis on the bottom edge of the housing. This allows the light emission to be changed from more narrow beam to more wide beam.
  • the side mirrors touch the head mirror during the swiveling process and are held on it.
  • the invention has for its object to improve a lamp of the type mentioned in such a way that the light intensity indicatrix of each individual lamp can be optimally adapted to different suspension heights and mounting distances without glare.
  • the lamp shown schematically in cross section in the single figure has an elongated box-shaped housing 1, on the one long side 1 a of which a fluorescent lamp 2 is preferably arranged. This is surrounded by a semicircular secondary mirror 3, which is followed by an approximately parabolically curved deflecting mirror 4 above a light exit opening 5 of the lamp.
  • the deflection mirror 4 is pivotally mounted on the longitudinal side 1b of the housing facing away from the lamp and, with its pivot axis 4a, also forms the boundary of the light exit opening on this side.
  • the light exit opening is limited by a bend 3a of the secondary mirror. This also prevents a direct view of the fluorescent lamp from below to the level indicated by an arrow 6.
  • the deflecting mirror 4 engages with its free edge 4b above the fluorescent lamp 2 under the secondary mirror 3. This ensures that no greater luminous flux losses occur when the deflecting mirror is pivoted into the position 4 'indicated in dashed lines.
  • the pivoting range of the deflecting mirror which can be determined within this range by means not shown, comprises an angle ⁇ of approximately 15 °.
  • the luminous intensity distribution body of the luminaire can thus be changed such that the light emerging from the light exit opening approximately in the direction of arrow 5a optimally fulfills the respective lighting task.

Claims (2)

  1. Luminaire de forme allongée avec un système optique à miroirs incorporé destiné à une lampe (2) en forme de barre et présentant une distribution assymétrique de la lumière, de préférence du type à appliquer sur des surfaces planes horizontales pour illuminer des surfaces verticales, le système optique à miroirs étant constitué par un miroir capteur (3) fixe entourant la lampe (2) à peu près en demi-cercle, et par un miroir déflecteur (4) pivotant autour d'un axe (4a) s'étendant dans le sens de la longueur du luminaire, ledit luminaire étant caractérisé en ce que le miroir déflecteur (4) et le miroir capteur (3) sont configurés de manière à pouvoir se chevaucher avec un écartement variable au-dessus et à l'arrière de la lampe (2), et en ce que l'axe de pivotement (4a) du miroir déflecteur (4) est prévu sur le côté de boîtier (1b) opposé à la lampe (2) et constitue la limite de l'orifice de passage de lumière (5).
  2. Luminaire selon la revendication 1, caractérisé en ce que la plage de pivotement du miroir déflecteur (4) forme un angle (α) d'environ 15°.
