- the installation height (L) is essentially determined by the Height of the installation frame 8.
- the installation height (L) is determined by two Parameters, the airflow and the distance of the Suspended ceiling 2 to the concrete ceiling of the room, determined.
- the Air flow is also a function of the gap width of Air gap 7 between the upper reflector part 5 and the lower reflector part 6.
- the gap width of the air gap 7 is on the one hand with the length (L) of the legs 21 of the Mounting frame 8 and the height (H) of the upper reflector part.
- the built-in frame 8 has at the bottom of a Support plate 14, in the present embodiment represents a circular ring. From the plane of the support plate 14 at least one tab 17, 17 'rises approximately in the right Angle to the support plate plane and the level of the suspended Ceiling 2. At the two tabs 17, 17 'are laterally each a leaf spring 18, 18 'attached, the attachment by spot welding or a similar fastener can be effected. At the flap 17 '', which is about 90 ° opposite the tabs 17, 17 'offset from the plane of the Supporting plate 14 protrudes, the legs 21, 21 'of a U-shaped bent angle sheet 11 by screwing in the Holes of the rows of holes 22 or by spot welding attached.
- the lower reflector part 6 is at its lower Edge folded approximately at right angles, so that encircling one Circular ring 13 is created, with its inner surface to the Outside surface of the support plate 14 is pressed.
- the upper edge the lower reflector part 6 has a pronounced structure, which is formed so that the upper edge at least one Schrage 12 has.
- Above the inclined portion 12 joins a cylindrical portion 12 'at.
- the Leaf springs 18, 18 ' have a bend at their free end on, which also about the same angle as the Bevel 12 directed inclined surface 18 'is formed, the due to the inward spring pressure of the Leaf springs 18, 18 'an upward pressure on the oblique wall of the portion 12 'of the lower Reflector 6 exerts.
- the entire Reflector 6 Fixed, but detachable in the mounting frame. 8 pinched.
- the structured formation of the upper edge the lower reflector part 6 also acts noise-reducing to the flowing through the air gap 7 Airflow out.
- Above the lower reflector part 6 is the arranged upper reflector part 5 in the rack 8 and with a fastening screw 30 on the angle plate 11th attached.
- the lower diameter (D1) of the spherical shell-shaped upper part 5 of the reflector slightly smaller than the diameter (D2) of the upper one cylindrical portion 12 of the lower reflector part.
- the upper reflector part 5 has a recess 16 on, through which a lamp holder 3 and the lamp 3 ' protrudes.
- the lamp holder 3 is on a bracket 31st attached, extending from the upper part of the u-shaped Angle plate 11 extends to the outside and in more appropriate Distance is bent at right angles to the lamp socket 3 with suitable fasteners to attach.
