Definitions
- the invention relates to a lamp according to the preamble of Claim 1.
- the invention is therefore based on the object of a lamp to improve the type mentioned so that such Change in the radiation pattern of the reflector in wide limits is possible.
- the adjusting devices for the adjustment of the Longitudinal edges of the reflector can be mechanical or electrical or be trained very simply in another way. In the case of elastically bendable reflectors, in any case both ends of a longitudinal edge can be adjusted if one uniform curvature of the respective reflector over its length should be achieved.
- Impermeable high-gloss reflector generally designated 10 10 from two symmetrical to the longitudinal center plane 12 of the lamp, reflector halves curved in profile 14 and 16.
- the edges 18 and 12 lying on the central plane 20 of the two reflector halves 14 and 16 are between approximately wedge-shaped, partially interlocking holding members 22 and 24 loosely pivoted.
- the two holding members 22 and 24 run parallel to the central plane 12 over the whole Length of the lamp.
- the longitudinal axis coincides with the central plane 12 26 one arranged above the holding members 22 and 24 Fluorescent lamp 28 together.
- Reflector 10 and fluorescent lamp 28 also run essentially over the whole Length of the lamp between two vertical end walls, from only those behind the plane of the drawing in Fig.1 End wall 30 can be seen. Both are on the end walls Holding members 22 and 24 and the fluorescent lamp 28 set.
- the two reflector halves are made 14 and 16 made of flexible material.
- the center of curvature is the stronger curved position 16 'approximately at point 38, during the center of curvature the weakly curved position 16 wide would be above the drawing sheet.
- the backdrop stone has locking devices, not shown, e.g. Clamping screws or the like, to be determined in one of the End positions 34 or 34 'or in a desired one middle position within the slot 36 on.
- Another, also not shown Embodiment is a motor drive for the adjustment of the sliding block 34 within the sliding slot 36 intended.
- any inclination, length and shape of the slotted slot 36 or other actuating devices, not shown, those in largely any and for the specialist easy to implement types can be formed can be many positions and curvatures of the reflector 10th adjust, assuming that not only on the front wall 30 lying in front of the drawing plane, but also on the left halves of the end walls 30 are similar Actuators are provided.
- the actuators can be linked to each other by gearbox or synchronization motor drives can be coupled so that an exact and easy adjustment of the reflector 10 within wide limits is possible.
- the adjustment of the reflector can either at the factory or on site for the respective purpose be made.
- FIG. 2 and 3 differs from that shown in Fig.1 in that that the reflector 10 made of rigid or less flexible material exists and in several contiguous longitudinal strips 46,48,50 and 52 is divided. On both sides of the Median plane 12 extending median strips 46 and on outermost longitudinal strips on both sides of the reflector 10 52 remain in the adjustment of the reflector 10 essential stationary. Between the fixed vertical stripes 46 and 52 are two movable longitudinal strips on each side 48 and 50 arranged both mutually also with the fixed median strip 46 along hinge connections 54 and 56 are articulated.
- a sliding block 34 is attached to each in a similar manner to the embodiment according to FIG. 1 in each a slot 36 in the end wall 30 to one can move upper end position 34 '.
- Locking devices not shown, or motorized Drives a determination in any intermediate positions allows along the slot slots 36. If the vertical stripes 48 and 50 sufficient over the entire length of the lamp are stiff, can be adjusted in this embodiment of the free edge 32 only at one end near the rear end wall 30 may be sufficient, this Adjustment movement through the stiffness of the strips up to front end wall 30 located in front of the drawing plane becomes. In extreme cases, the front end must be at the front End wall 30 is not even guided in actuators but can be loosely attached to this front wall Follow positioning movement on the rear partition 30.
- the stationary outer longitudinal strips 52 of the reflector 10 do not contribute to the change in this embodiment Emission characteristic of the reflector 10 by adjustment the same, but only serve to prevent direct glare from the side or only slightly light emitted above.
- the adjustment device is open the left side of the reflector 10 by moving the Sliding block 34 in the position 34 'a pivoting of movable longitudinal strips 48 and 50 of the reflector 10 in one each steeper position 48 'or 50'. While the Radiation characteristic of the right half of the reflector 10 remains as shown in Fig. 2, adds up now the radiation pattern of the left half of the Reflector 10 according to Figure 3 on the radiation characteristic of right half. Since everyone reflected from the left half 48 ', 50' Beams in a much wider angular range 44 fall, there is now a strongly asymmetrical Beam pattern up and right.
- each desired setting of the reflector already in the factory or adjust on the spot as needed. It must be for the most diverse applications only a single lamp are produced, which then the respective application or adapted to the desired radiation pattern can be.
