Definitions

  • the invention relates to a bed reading lamp, in particular for hospital rooms, with a lamp housing which can preferably be attached to a room wall and has at least one tubular, elongated lamp and a reflector and at least one light-transmitting cover which closes a light outlet opening provided in the lower region of the housing and serves to guide the light, with a cover lower first section and an adjoining front upright second section.
  • the problem underlying this invention is to achieve a light distribution in such a luminaire in such a way that the cut-out angle is approximately 30 ° with respect to the vertical and approximately 7 ° with respect to the horizontal, so that neither the person lying in bed from the light of the The lamp in the bed on the opposite wall is still blinded.
  • the invention proposes that the first section of the cover lying under the lamp has a part inclined relative to the horizontal by an angle ⁇ of approximately 6 to 10 °, which on its side facing the lamp has an axis the lamp has parallel prismatic profiling and the second section, which likewise has a prismatic profiling on its inside, encloses an angle ⁇ of approximately 40-50 ° with respect to the horizontal.
  • FIG. 1 shows a cross section through a bed reading lamp
  • FIG. 2 shows a cross section through the light-guiding cover on an enlarged scale compared to FIG. 1
  • 3 shows the light distribution
  • FIGS. 4 and 5 are detailed representations of different sections of the cover on an enlarged scale compared to FIG. 2.
  • Fig. 1 shows the cross section of a lamp equipped with two tubular lamps 1 and 2 with a housing 3, which is arranged by means of a fastening device 4 on a wall directly or on a supply channel attached to a wall.
  • Various supply lines 5 - 9 are laid here in the wall-side area of the housing 3.
  • a substantially horizontal partition 12 divides the luminaire housing 3 into a section 13 serving for room lighting with a translucent cover 14 and the lamp 1 and into the actual bed reading lamp 15 with the lamp 2 and the cover 16
  • FIG. 3 The light distribution expected from this bed reading lamp 15 is shown schematically in FIG. 3.
  • the Ausblendwinkel respect to the vertical 17 should be about 30 °, the Ausblendwinkel relative to the horizontal about 18, so that neither the 7 ° geblen of his reading light lying in bed - will still be det opposite to the opposite chamber wall.
  • line 32 shows the extent of the light intensity as a function of the respective angle between the vertical 17 and the horizontal 18.
  • the cover 16 which is shown in FIG. 2 on an enlarged scale compared to FIG. 1, serves for this light distribution according to FIG. 3.
  • the first section 20, which lies under the lamp 2, is inclined by an angle ⁇ of approximately 6-10 0 with respect to an imaginary horizontal plane 23.
  • a prismatic profile 24 parallel to the axis of this lamp is provided on its side facing the lamp 2, a prismatic profile 24 parallel to the axis of this lamp is provided.
  • This inclined part 21 is adjoined by a horizontally lying part 22, against which the profiling 24 runs out, so to speak, so that its walls are smooth and this horizontally lying part 22 then merges into the second section 25, which is also on its inside, which faces the lamp 2, carries a prismatic profile 26 and this section 25 is inclined at an angle ⁇ of approximately 40-50 ° with respect to the horizontal 23 mentioned several times.
  • edge-side profile strips 27 and 28 serve to fasten the cover 16 to the housing 3. From FIG. 1 it can also be seen that the actual light exit plane E of the housing 3 and the cover 16 with their sections 20 and 25 are not congruent.
  • the cover 16 with its profiles and its edge strips 27 and 28 is made in one piece from a translucent plastic.
  • FIG. 4 illustrates the prismatic profiling 24 of the part 21 of the first section 20 on a scale that is considerably enlarged compared to FIGS. 1 and 2. From this it can be seen that the opening angle of the prismatic profiles 24 is approximately 45 to 50 ° and the center plane M which can be placed through the apex S is inclined to an imaginary vertical plane V and that the angle of inclination 29 between these two planes is greater than the angle of inclination d. of part 21 of first section 20 with respect to horizontal 23.
  • the height of the prismatic profiles 24 decreases with a simultaneous increase in the opening angle towards the horizontal part 22 of the first section 21 of the cover 16, this decrease not being linear.
  • the number of prismatic profiles 24 having the same height H is greater than the number of profiles having a reduced height h, the ratio of these profiles being approximately 2: 1.
  • a single prismatic profile 24 lies above the base width A (FIG. 4). In principle, it is possible to provide a plurality of such profiles over this base width A, these profiles then have to be reduced in the corresponding angular relationships without in principle influencing the light distribution. However, such a multiplication of the prismatic profiles causes increased tool costs and increased tool wear.
  • FIG. 5 shows the prismatic profile 26 in the second section 25.
  • the opening angle of the profile is approximately 90 °.
  • This profiling 26 is arranged such that the width B of the respective upper flank 30 is almost three times as large as the width B of the respective lower flank 31.
  • Fig. 1 it can be seen that all sections of the cover 16, which have profiles 24 and 26, are below the light source formed by the lamp 2.
  • the axial direction of this lamp 2 is parallel to the longitudinal axis of the prismatic profiles.
  • the lamp 2 is also arranged above the profiling 24 of the inclined part 21 of the first section 20 of the cover 16, preferably above the rear profiling facing away from the front inclined section 25.
  • the invention was explained above with reference to a bedside reading lamp for hospital rooms, which also has a second lamp 1, which is used for indirect room lighting.
  • This lamp used for room lighting is not essential to the invention.
  • the other design of the bed Reading light as described above, in particular the arrangement of different supply lines 5 - 9 is not essential for the invention.
  • the bed reading lamp can also be designed differently. If it was described above that the bed reading lamp is arranged on a wall or on a supply duct fastened to a wall, this is also not essential for the invention. It would be quite conceivable to arrange the bed reading lamp on a support directly connected to the bed frame.
