Definitions

  • the invention relates to a lamp according to the preamble of claim 1.
  • a lamp is already known from EP-AI-8.004.
  • the invention has for its object to design such a top mirror so that it takes up as little height as possible and can still be used for channel mirrors with different light distribution characteristics.
  • the luminaire efficiency should be affected as little as possible.
  • Another object of the invention is to design the upper mirror in such a way that it can be manufactured and assembled with high accuracy with comparatively little effort.
  • the inventive solution to this problem is characterized in claim 1.
  • the upper mirror is then designed to be flat and is only shaped by a few millimeters in the area above the lamp, with only flat walls occurring which can be easily manufactured with high accuracy.
  • FIG. 1 shows a channel mirror 1 which is symmetrical with respect to a vertical plane 21 in cross section. It is formed by two mutually opposite side mirrors 11, 12, which delimit a light exit opening 100 between them and between which transverse lamellae 10 are arranged.
  • the side mirror shown is approximated to a parabola with a focal length of 1.07 ⁇ 5%, based on the diameter D.
  • the focal point lies in the longitudinal axis 20 of the lamp; the axis angle ⁇ between the main axis and the vertical is 40 ° ⁇ 2 °.
  • the opening between the side mirrors above the lamp 2 is covered by an upper mirror 13, which is also symmetrical to the vertical plane 21 and runs parallel to the light exit opening 100 and to the longitudinal axis 20 of the lamp. It has a mirror section 130 in the middle, which is formed by two identical, flat walls 131, which are symmetrical to the vertical plane 21 and enclose a central angle ⁇ Lam of 120 ° between them.
  • the mirror section 130 is adjoined on both sides by flat outer parts 132 with a width b and by this flat edge parts 133.
  • the edge parts 133 run in a roof plane at a distance H parallel to the light exit opening 100.
  • the outer angle ⁇ of the outer parts 132 against this roof plane is 10 ° ⁇ 1 °.
  • the width of the previously mentioned lamp is 8.3 mm.
  • the widths a and b are measured in the roof plane.
  • the upper mirror according to the invention is also suitable for a channel mirror for two lamps running parallel to one another: in this case the essentially flat upper mirror has two forms of the type described, the plane of symmetry of which in each case passes through the longitudinal axis of the associated lamp.

Claims (5)

  1. Lampe comportant un miroir en forme de gouttière (1) comportant deux miroirs latéraux parallèles (11,12) et des lamelles transversales (10), disposées entre ces miroirs, et un tube fluorescent (2) de diamètre D , disposé entre les miroirs latéraux de telle sorte que son axe longitudinal (20) s'étend a une distance verticale B , parallèlement à l'ouverture de sortie de la lumière (100), limitée par les miroirs latéraux, et
    un miroir supérieur (13), qui recouvre l'espace intercalaire présent entre les miroirs latéraux au-dessus du tube (2), est parallèle à ce tube et possède une section en forme de V en coupe transversale (130), dirigée vers la lampe, comportant des parois planes (131) et symétrique par rapport au plan vertical (21) passant par l'axe longitudinal (20),
    caractérisée par le fait
    que le rapport de la hauteur hors-tout du miroir en forme de gouttière au diamètre D du tube est égal à 2,77 ± 10 % et que le rapport de la distance verticale B entre l'axe longitudinal (20) du tube et l'ouverture de sortie de la lumière au diamètre D du tube est égal à 2,115 ± 10 %,
    que la largeur a de la section (130) du miroir est déterminée par le rapport a/D = 0,33 ± 1 % et que les parois (131) de la section (130) du miroir font entre elles un angle central (α) égal à 120° ± 1,
    qu'a la section (130) du miroir se raccorde, des deux côtés, une partie extérieure plane (132) possédant la largeur b , qui est déterminée par le rapport b/D = 0,32 ± 1 %,
    que le miroir supérieur (13) est situé par ailleurs dans un plan de fermeture supérieur, qui est parallèle au plan de l'ouverture de sortie de la lumière (100), et que l'angle (β) entre ce plan de fermeture supérieur et chaque partie extérieure (132) est égal à 10° ± 1°.
  2. Lampe suivant la revendication 1, caractérisée par le fait que chaque miroir latéral comporte, au voisinage de l'ouverture de sortie de la lumière (100), une section latérale rectiligne (110), qui fait avec le plan de l'ouverture de sortie de la lumière un angle d'inclinaison (γ) égal à 82° ± 1° et dont le rapport de la hauteur h, mesurée parallèlement au plan vertical (21), au diamètre D est égal à 1,07 ± 20 %.
  3. Lampe suivant la revendication 2, caractérisée par le fait que par ailleurs pour une distribution de lumière Batwing, le miroir latéral possède une forme se rapprochant d'une parabole, dont le foyer est situé sur l'axe longitudinal (20) du tube, que le rapport de la distance focale de cette parabole au diamètre D est égal à 1 07 ± 5 % et que l'axe principal de cette parabole fait par rapport au plan vertical (21) un angle (ε) égal à 40° ± 1°.
  4. Lampe suivant la revendication 2, caractérisée par le fait que pour l'obtention d'une caractéristique BAP ou sombre, le cintrage des miroirs latéraux se rapproche par ailleurs d'une parabole, dont le foyer est situé sur l'axe longitudinal (20) du tube, que le rapport de la distance focale de cette parabole au diamètre D du tube est égal à 0,84 ± 5 % et que l'axe principal de cette parabole fait avec l'axe vertical un angle (ε) égal à 25° ± 1°.
  5. Lampe suivant l'une des revendications 1 à 4, caractérisée par le fait que le diamètre D du tube est égal à 26 mm et que la largeur de l'ouverture de sortie de la lumière est égale à 100 mm.
