Definitions
- the invention relates to a reflector and shielding system for a ceiling light with a roof reflector, a tube reflector arranged vertically below the roof reflector, the one containing the axis of symmetry Section having parabolically curved inner wall surfaces, and at least one between the roof reflector and the tube reflector horizontally arranged fluorescent lamp.
- Reflector and shielding systems of the specified type are made DE-U-88 17 065 known.
- the roof reflector is pot-shaped and a tube reflector is concentric in its opening let in as one by rotating two parabola branches generated body of rotation with both the interior and surface is concavely curved to the outside.
- Lamellar Light guiding elements extend from the tube reflector radiating outwards towards the roof reflector.
- the slat-like Light guiding elements each have two parabolic legs in a V arrangement.
- Such a lamp has the disadvantage that the roof reflector designed as a smooth reflecting surface produces a distorted reflection of the fluorescent lamp, that gives the viewer the impression that he is direct looks into the fluorescent lamp. He is blinded.
- the invention has for its object a reflector and To create a shielding system for a ceiling lamp that at simple construction an all-round distribution of light with maximum Luminous efficacy guaranteed.
- Tube reflector in a plate-shaped grid shield is arranged, which is formed from crossing webs Raster cells have parabolically curved reflection surfaces.
- a reflector and shielding system in which an optical primary lighting system is coupled with an optical secondary lighting system, is designed so that the lamp luminous flux in a uniform light distribution (all-round distribution) within all solid angles gamma 60 ° to the vertical, with ⁇ 200 cd / m 2 luminance limitation emerges from the ceiling light.
- the combination of the internally parabolically shaped tube reflector (round reflector) with a plate-shaped grid shield, which interact with the roof reflector and preferably have smooth reflection surfaces, ensures excellent light output, optimal illumination of a room and limitation of direct glare.
- the grid cells of the grid shielding are advantageously square and it is envisaged that the tube reflector in a central recess in the middle of the grid shield is.
- the tube reflector is preferably approximately double as high as the grid shield, and it is so in the grid shield arranged that he with the top of the grid shield ends flush and with a lower section protrudes beyond the bottom of the grid shield.
- the outer periphery of the lower section is cylindrical, preferably circular cylindrical.
- the grid shield can protrude from the top of this have outer frame parts on which electrical connection elements intended for the horizontal fluorescent lamp are.
- Grid shielding and tube reflector form an independent unit that is easy to handle from its material. At Manufactured from plastic, they can be made in one piece his.
- the frame parts are also molded on. All Reflective surfaces are mirrored.
- the roof reflector is essentially pyramidal with polygonal Base area designed.
- the base area is preferably that forms the opening of the roof reflector, square, so that the outer surface of four edges colliding Consists of triangles that share a common apex outside of the Own space.
- the triangles can be flat or light be arched.
- the square roof reflector is symmetrical arranged above the tube reflector, which is in the square Grid shielding sits. The quadrilaterals are preferred.
- the pyramid shape gives the roof reflector from the center crease lines running to the corners, which form the reflection surface interrupt. This ensures that the lamp light from the four triangular reflection surfaces in different Directions is reflected, so that for the viewer none coherent reflection of the fluorescent lamp (s) is created, that could bother him.
- the fluorescent lamp is lying flat arranged immediately above the grid shielding and their upward directed, broadly emitted light component is sent against the reflective surfaces of the roof reflector and reflected obliquely into the room by them, whereby no luminance concentrations occur due to the kink lines.
- a downward light component of the fluorescent lamp (s) is from the tube reflector with parabolic Directed central opening.
- the tube reflector ensures that a proportion of light rotationally symmetrical over the high-gloss and parabolically shaped reflection surfaces in predetermined Angles is sent down.
- the vast majority of the light emitted by the fluorescent lamp hits directly or as a reflection from the roof reflector into the room or on the grid shield, the large number of square, concave Reflective surfaces distribute the light evenly all around, so that the room is fully illuminated.
- the opening of the roof reflector preferably has approximately that triple the width of the grid shield. This is proportionate large diameter of the roof reflector causes a flat rise the reflection surface from the opening edge to the closed Tip and it turns out that that's from the grid shield and the tube reflector reflected light from the roof reflector is emitted in the direction of the ceiling. This is done a brightening of the ceiling area while avoiding the cave effect.
- the outer surface of the tube reflector is in the top, in the grid shield housed, section circumferentially in four arcs divided with four tendon sections alternate with the straight surfaces of the square central recess connect the grid shield.
- the ceiling lamp which in the example shown as a recessed lamp is designed for installation in a ceiling a square housing body 10, which sunk into a Ceiling can be installed.
- the housing body 10 In the housing body 10, the is open at the bottom, there is a square Roof reflector 11, which has a flat pyramid shape.
- the amount of Roof reflector 11 is slightly smaller than the height of the Housing body 10 so that the roof reflector 11 completely in the housing body 10 is sunk.
- Four triangular surfaces 11a, 11b, llc and 11d (Fig. 2) butt with their tips in the Dome center of the roof reflector 11 together and unite to a reflective surface with four crease lines that extend from the Center to the four corners of the square roof reflector 11 go straight.
- the lower square opening 19 of the roof reflector 11 is surrounded by a frame 12, the attachment serves on the housing body 10.
- the faces of the triangles Ila to 11d can be flat or - as shown in Figure 1 - be slightly concave.
- the reflective surface is mirrored.
- the roof reflector 11 can be made of metal or plastic be made in one piece. It forms an optical secondary lighting system.
- each grid cell 14 is of four in vertical Direction of concave (parabolic) and horizontal Direction straight reflection surfaces 15 limited an upper smaller opening 16 and a lower larger opening 17 define.
- Four circumferential straight rows of Four grid cells 14 each delimit the area of four grid cells engaging central recess 18 in which a tube reflector 20 is arranged so that its longitudinal axis is perpendicular runs to the level of the grid shield 13.
- the parabolic shaped tube reflector 20 is about twice as high the grid shield 13.
- the half-measure (radius) of the tube reflector 20 corresponds essentially the edge length of a grid cell 14.
- Grid shield 13 and tube reflector 20 form an optical Primary lighting system.
- the diameter of the roof reflector 11 is about three times as large at its opening 19 the grid shield 13.
- the tube reflector 20 is cylindrical on its outer surface, with four arcs circumferentially on the upper section alternate with four tendon sections 25 to which straight Connect surfaces of the central recess 18 and the lower one Section 20a has a circular cylindrical shape on the outside. Its circular Center opening 21 is parabolic, i.e. the inner wall surface 22 is by rotation of a parabolic load originated and concave. The lower opening 23 is larger than the top opening 24. The diameter of the tube reflector 20 corresponds approximately to the dimensions of four grid cells 14 of the midfield used to form the central recess 18 are omitted.
- the square parabolic inner surfaces 15, 22 of the grid cells 14 and 22 of the tube reflector 20 are mirrored.
- the tube reflector 20 can be made in one piece with the grid shielding 13 be made of plastic.
- the grid shield 13 with the tube reflector 20 is included Using vertical struts 30 with respect to the lower opening 19 of the roof reflector 11 suspended.
- One strut is 30 each at the four corners of the grid shield 13 in sockets 31 (Fig. 1) slidably held so that the spacing of the screen / tube reflector assembly 13, 20 to the opening 19 of the roof reflector 11 is adjustable. Also allow the Strive 30 to peel off the raster / tube reflector assembly 13, 20 for repair or cleaning.
- the top ends of the Struts 30 protrude through the fold lines of the roof reflector 11 holes lying through and are either on this itself (Fig. 1) or fixed to the wall of the housing body 10.
- the Edges of the roof reflector 11 and the grid shield 20 are parallel to each other.
- the grid shield 13 is on its top with this towering outer frame parts 32 provided during training the assembly of grid shielding and tube reflector 13, 20 molded in one piece from plastic with these parts could be.
- the frame parts 32 carry the bushings 31 for the Struts 30 and they also serve to attach electrical Connection elements for sockets 35 of fluorescent lamps 33.
- FIG. 3 shows, there are a total of four fluorescent lamps 33 provided horizontally next to each other, the versions 35 two adjacent fluorescent lamps 33 on one End and the versions 35 of the other two side by side arranged fluorescent lamps 33 arranged at the other end are.
- the fluorescent lamps 33 are compact fluorescent lamps with a U-shaped glass tube that only at one end has a socket 35.
- Each fluorescent lamp 33 is lying arranged, the two legs of the glass tube itself immediately above the top of the grid shield / tube reflector assembly 13, 20 and the central opening 21 span the tube reflector 20. About 60% of the total Lamp surface is above the central opening 21 and the rest about 40% lie above the grid cells 14.
