Definitions

  • the invention relates to a bedside reading lamp, especially for hospital rooms according to the features of the preamble of claim 1.
  • a bed reading lamp for hospital rooms of this type is known from GB-PS 955 404. It has an upper light exit opening, through which the room in which the luminaire is mounted is indirectly irradiated, with most of the light exiting through this light exit opening. Furthermore, an angular cover is provided on this lamp, specifically on its side facing the hospital bed, which has the task of diffusely scattering some of the light emitted downwards.
  • 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 the lamp is still blinded to the one in the bed on the opposite wall, but there is still enough light for the person lying in bed, for example to work something, especially to be able to read.
  • the invention proposes those measures that are the content and subject of the characterizing part of claim 1.
  • 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.
  • the devices 10 required for the operation of the lamps 1 and 2 are accommodated in a wall-side chamber 11 of the housing 2.
  • 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.
  • the light distribution expected from this bed reading lamp 15 is shown schematically in FIG. 3.
  • the masking angle with respect to the vertical 17 should be approximately 30 °
  • the masking angle with respect to the horizontal 18 should be approximately 7 °, so that neither the person lying in bed is blinded by his reading lamp nor his counterpart on the opposite wall of the room.
  • 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 at an angle a of approximately 6-10 ° 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 followed 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 the inside thereof faces the lamp 2, carries a prismatic profile 26 and this section 25 is inclined by 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 that 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 a of the Part 21 of the first section 20 with respect to the horizontal 23.
  • the height of the prismatic profiles 24 decreases with simultaneous enlargement of 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 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 being reduced in the corresponding angular relationships without thereby to influence the light distribution in principle. 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 profile 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.
  • 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 configuration of the bed reading lamp as described above, in particular the arrangement of various 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, then 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.
