  • the luminaire should comply with defibrillation specifications according to DIN-EN 12464 and thus achieve the necessary UGR values (unified glare ratio)
  • the LEDs on the circuit board are arranged in a single row, and the LED board is also mounted on a cooling profile formed as an aluminum profile.

  • a transparent optic can be fixed to the cooling profile; wherein the diaphragm and the optics can also be designed as an integral component.
  • the optic is formed as an injection molded part.
  • other manufacturing methods are possible. Due to large differences in wall thickness occurs in the injection molding process, a deformation of the optics during cooling after removal from the injection mold on. This deformation of the optics is reversed by the attachment to the cooling profile, in particular the insertion into the cooling profile, so that the entire look is flat.
  • the one-sided positioning of the optics in the longitudinal direction preferably takes place via a latching nose, which is introduced in the optics guide profile.
  • two optical disks are used for each light band element, which are pushed towards one another from the opposite, open ends in the cooling profile to form a closed and consistent look. In the installed position, these optical discs are thus secured against falling out of the cooling profile.

  • the laminating element is preferably designed to be resilient and thus prevents use between two impact-side adjacent optical disks, that the two optical disks can move further in the direction of the center or the outer edge of the light band element, so it holds the optical disks bridging the separation or joint top side and therefore not visible to the viewer against each other in installation position under bias.
  • the light band element can also meet the protection class IP40 and further ensured by this structure that the optical discs can move in thermal expansion in the longitudinal direction within the appropriate tolerances, without causing deformation, mechanical stresses or crackling noises occur.
  • the resilient laminating element may comprise, for example, a substantially rigid and plate-shaped longitudinal web for defining a longitudinal direction, which is preferably paired and transverse to the longitudinal direction projecting, preferably integrally formed struts comprises.
  • the longitudinal web In the installation position, the longitudinal web extends with its longitudinal direction transversely to the longitudinal direction of the light band and thus covers from the inside - the top - the joint between two adjacent optical discs.

  • By inserting the optical disks also creates the ability to fix the optics in the middle, so that for the optics with temperature fluctuations only an extension in the direction of the center of the light band is possible.
  • Through this quasi “floating storage" of the optical disks in the cooling profile mechanical stresses or clicks are effectively avoided.
  • Different LED boards can be fixed to the cooling profile as needed, if the optics are in a linear (extrusion-like) version. In this case, only the position transverse to the longitudinal direction of Light band element for the light distribution significantly, the LED distance in the longitudinal direction but has no significant effect on the light distribution. As a result, the number of LEDs can be easily varied without changing the optical system.
  • the subject of the disclosure is also - regardless of the light band element of the other disclosure objects - a novel reflector aperture, which is arranged in the installed position between the light source (preferably LED strip) and the optical discs.
  • UGR Unified Glare Ratio
  • the UGR aperture ensures that the light is blocked at an angle of less than 25 degrees to the horizontal, with the aperture mainly reflecting the light downwards.
  • the diaphragm essentially serves as a reflector and collects the light which would not escape from the luminaire housing without a UGR diaphragm.
  • This reflector aperture thus allows effective glare in the longitudinal direction, compensates for light losses by using the laterally emitted light, which could not escape from the interior of the light band without aperture. Furthermore, the reflector panel conceals electronic and mechanical components, such as screw heads. The glare is also realized when LEDs are partially behind the aperture, which makes the use of boards with different LEDs or LED positions is particularly easy. Although the reflector aperture is optimized for a particular LED position, the LEDs may still be at a different distance. At different LED intervals, some of the LEDs behind the bezel may be obscured. Nevertheless, the glare reduction will remain comparable for a comparable luminaire luminous flux. This is the case because almost the entire area between the panels is filled by the LEDs. Using a different LED spacing with the same aperture will reduce luminaire efficiency. The glare-free property remains intact.
  • the disclosure also proposes - again separately from the other objects described above (phase selection device, reflector panel, Kasch michmaschineselement) and not limited to a lighting system - a special mounting screw before, which is operated without tools.
  • This mounting screw consists essentially of two components. In the delivery state, the two components, namely the actual screw, which is preferably designed as Allen screw made of metal, and an actuating or rotating element (preferably made of plastic), which is captive in the delivery state connected to the screw to form the mounting screw. This connection can be done by injection molding of the screw, for example by injection molding.
  • the encapsulation takes place in such a way that the wing can transmit a large torque to the screw when rotating about the screw longitudinal axis, for example by profiling on the inner surface of a screw surrounding the screw in the mounting position ring of the rotary member from which two pivot arms extend.
  • the rotating element can be removed from the screw, since the wall thickness of the plastic part in the corresponding area has a thinner wall thickness.
  • the wing is shaped so that it is easily rotatable and it preferably has an undercut, can engage behind the finger to exert a sufficiently high force in the longitudinal axis of the screw.
  • the rotary member is designed as a form-fitting insertable rotary handle in the Allen screw.
  • the preferred embodiment provides that the remote from the screw rotary element can later be placed back on the screw and used to operate the screw; an alternative embodiment provides that the rotating element after removal can not be re-attached to the screw.
