Definitions
- the present invention relates to a lamp with a tubular Gas discharge lamp and a concave curved reflector in front of a Partially translucent diffuser is arranged.
- a lamp of this type is, for example, from WO 01/59364 A1 by the applicant is known and will be briefly explained below with reference to FIG. 7.
- the individual elements of the lamp are inside a box-shaped Luminaire housing 107 arranged when mounting the lamp in the ceiling of a room to be illuminated is sunk.
- a rod-shaped serves as the light source Gas discharge lamp 101, under or - seen in the direction of radiation - in front of the one grid 106 consisting of side reflectors and transverse slats is arranged. The The majority of the light emitted by the lamp 101 is converted via this grid 106 radiated downwards.
- the gas discharge lamp 101 is emitted by a concave reflector 102 spanned, the side wings arranged substantially next to the lamp 101 are.
- a diffuser 103 is further arranged, the two common with the reflector 102 includes so-called light chambers 104.
- the diffuser 103 and the Reflector 102 together at their ends remote from lamp 101.
- a part of the light emitted by the lamp 101 is transmitted via the Reference numerals 105 provided so-called light entry surfaces in the Light chambers 104 coupled in and emitted downwards via the diffuser 103. This also makes the area of the luminaire surrounding the grid 106 light brightened, which creates a visually appealing lighting effect.
- the diffuser 103 is formed by a one-piece component formed, which - as shown in Fig. 7 - is curved in both side regions and has a central bend, which the two curved side areas connects with each other.
- a component can for example be made of PMMA Injection molding processes are manufactured.
- This one-piece design of the diffuser is, however, disadvantageous viewed as the possibilities to change the dimensions of the lamp, are restricted by this.
- the reason for this is that to manufacture the one-piece diffuser a specially prefabricated tool is required, which exclusively for the manufacture of the diffuser with the specified dimensions suitable is. If you want to create a luminaire with different dimensions, do so would need another tool to create a diffuser with the new ones Dimensions are provided, but this reduces the manufacturing costs for the Overall lamp would be significantly increased.
- the one-piece diffuser in the special form shown only made of polymethyl methacrylate (PMMA) can be.
- PMMA polymethyl methacrylate
- PC polycarbonate
- the present invention is therefore based on the object of a lamp to create the type described above with the same lighting effects can be achieved as in the known lamp, but the previously mentioned disadvantages can be avoided.
- the lamp according to the invention initially has a tubular Gas discharge lamp and at least one - from the area to be illuminated seen - on both sides next to the lamp arranged concavely curved Reflector. There is also a next to the lamp but in front of the reflector arranged partially translucent diffuser provided. This consists of two separate transparent plates that can be detached on both sides next to the lamp Fasteners of the lamp are connected.
- the two diffuser disc halves are thus no longer connected in one piece, but instead are available individually, being simple by using suitable fasteners Can be arranged in the desired position. Because the effort to Production of these individual transparent plates is however considerably less than the one for producing the one-piece diffuser part described above, can Diffuser plates in different dimensions are easily provided become. The possibilities of lights in different sizes and dimensions are significantly increased.
- the transparent plates forming the diffuser can also be used in a simple manner just be trained. This will make production of the Diffuser allows, because the diffuser discs simply from a larger plate in the corresponding dimensions can be cut. The Manufacturing costs for the lamp can be considerably reduced become.
- the reflector has on its outer edge a support surface facing the lamp exhibit. This can be done, for example, by appropriate crimping of the Reflector edge can be achieved.
- a special spring element provided, which also has a bearing surface on a side deflectable spring arm is attached. The installation of the diffuser plates on the lamp is thereby greatly simplified since the plate only against the spring element must be pressed and then on the outer edge of the crimping of the Reflector can be placed. Then the spring element again relieved, the diffuser plate is simple but safe in the desired Position held.
- the lamp can - seen from the area to be illuminated - in front of the lamp furthermore have a light distribution element, which is, for example, a Grid or a partially translucent perforated plate can act.
- a light distribution element which is, for example, a Grid or a partially translucent perforated plate can act.
- this additional light distribution element is also on the previously described Fastening springs for the transparent diffuser plates attached.
- the diffuser and the reflector form in an analogous manner to the known luminaire two light chambers arranged to the side of the lamp, the ratio of Width of a chamber to the greatest distance between the reflector and the Diffuser is at least 4: 1 and particularly preferably in the range between 4: 1 and 5: 1. This makes a very flat lamp with very good lighting properties created.
- the reflector is preferably made of two concavely curved reflector parts formed, extending from the center of the lamp to one side of the Extend the luminaire housing.
- Figures 1 to 3 show an embodiment of a lamp according to the invention a recessed ceiling light, the elements of which are in a box-shaped Luminaire housing 7 are arranged, which with the help of mounting elements 9 in the Ceiling of a room to be illuminated is sunk.
- a recessed ceiling light the elements of which are in a box-shaped Luminaire housing 7 are arranged, which with the help of mounting elements 9 in the Ceiling of a room to be illuminated is sunk.
- a large part of the the gas discharge lamps 1 - which are preferably fluorescent lamps acts - emitted light emitted downwards via the grid 6, the Shapes of the grid 6 are chosen so that the light emitted downwards cross-glare to a certain degree.
- the lamp according to the invention is thus especially suitable for lighting rooms with VDU workstations, because Glare effects on screen surfaces and for people present in the room are largely avoided.
- a perforated plate which is backed with foils, for example, or other optical elements are used, for example diffusers or Prism structures.
- a single lamp to the illustrated two-lamp version of the lamp use.
- a reflector On both sides next to the lamp there is a reflector, which is actually is formed from two concavely curved reflectors 2, which extend from the center of the Extend the luminaire housing to the outside.
- a diffuser plate 3 In front of the reflectors 2 is in each case a diffuser plate 3 is arranged.
- the reflectors 2 and diffuser plates 3 run each at their ends remote from the lamps 1 and thus close two light chambers 4 arranged on both sides next to the lamps 1.
- the Light entry surfaces for the two light chambers 4 are each of the Upper edge of the grid 6 and the reflectors 2 limited. Because the diffuser plates 3 each up to the upper edge of the corresponding side wall of the grid 6 extends, it is avoided that the lamps 1 arranged above the grid 6 can be viewed directly from the side and thus glare effects arise.
- the width a of the light chambers 4 is preferably at least four times as large the height b of the light chambers 4, i.e. the distance between one Light entry area and the outer end of a light chamber 4 is larger than that Four times the greatest distance between the reflector 2 and the diffuser 3. Die This makes the luminaire very flat and elegant.
- the Size ratio between width a and height b of a light chamber 4 is particularly preferably in the range between 4: 1 and 5: 1.
- the diffusers 3 on both sides of the lamps 1 despite the low height of the luminaire over its entire width in one uniform brightness appear.
- the one shown here contributes to this curved shape of the reflectors 2, which have a corresponding light control causes light rays coupled into the light chamber 4, on the other hand can Additional measures may be provided to achieve the desired level To achieve luminance.
- the reflectors 2 could be configured in this way be that they unite in the outer areas away from the lamps 1 have a higher degree of reflection than in the immediate vicinity of the lamps 1.
- the diffusers 3 could also be in the outer Areas have a higher light transmission.
- the area behind the reflectors 2 within the luminaire housing 7 can be used, for example, to arrange the control devices for the lamps 1 be used. As shown in Fig. 1, for example, on the An electronic ballast 8 can be arranged on the bottom side of the housing 7.
- the reflectors 2 trained to be partially translucent and in the ones behind the reflectors Arrange areas of additional lamps, creating additional lighting effects can be achieved. This possibility is detailed in WO 01/59364 A1 described. Generally it should be pointed out that all in the Variants described for WO 01/59364 A1 for the arrangement of lamps and Use of partially transparent or colored optical elements also with the present luminaire according to the invention can be realized.
- the special feature of the lamp according to the invention is in the Realization and storage of the diffuser discs 3. According to the present Invention, these are two separate transparent disks that pass through special fasteners are held in the lamp.
- the storage of the Diffuser discs 3, which will now be explained, can in particular the 2a and 2b are taken.
- the diffuser plate 3 lies on with its outer edge an inward contact surface 2a.
- This contact surface is through a flange of the reflector 2 is formed, so that a holder of the Plates 3 on the respective outside in a simple manner and without the Need for additional measures.
- FIGS. 4a and 4b 4c shows a punched-out bleaching part which forms a Fastening spring 5 is deformed.
- a fastening spring 5 consists of three parts, a base 5a, a side surface forming a spring arm 5b and a support surface 5c.
- the base 5a has two bores 5d, which attach the Fastening springs 5 on the lamp housing 7 via two screws 10 enable, as shown in Figures 1, 2b and 3.
- Perpendicular is angled to the base 5a but also aligned vertically Arranged spring arm 5b, on the underside of which a support surface 5c is formed, which in turn is perpendicular to the two previously mentioned surfaces 5a and 5b is aligned.
- the sheet metal part shown in Fig. 3c is integrally formed and can along the shown fold lines easily deformed to the final shape become.
- the Spring arm 5b are then laterally deflected in the direction of the arrow (see FIG. 4a), so that a simple hanging of the diffuser plate 3 as shown in Fig. 2b is made possible.
- a diffuser plate 3 then takes place in that the plate 3 initially is pressed against the spring element 5 such that the spring arm 5b follows bends inside.
- the outer edge of the diffuser plate 3 is then crimped of the reflector 2a and then the spring arm 5b is relieved, whereby the plate 3 is clipped into the desired position in a simple manner.
- the fastening spring 5 is not only the Holding the diffuser plates 3 is used.
- the mounting springs 5 also serve to hold the grid 6.
- the grid 6 has one in its end regions of the side reflectors suitable profiling with a recess 6a, with the help of which Clamping effect achieved with the mounting springs 5. Because the side walls of the grid 6 are even slightly resilient, the grid 6 can be installed after the Diffuser plates 3 in a simple manner from the bottom to the spring elements 5 be clipped on.
- the diffuser plates 3 are designed as flat plates in the example shown, so that they can be manufactured in a particularly simple and inexpensive manner. However, it would also be conceivable to have the plates curved in a slightly concave manner Provide form. The assembly of the concave curved plates in the lamp would again be done in the same way as previously described.
- a material for the diffuser plates can both polymethyl methacrylate (PMMA) and Polycarbonate (PC) can be used.
- FIG. 5 shows a reflector 2 seen in section on its own. This exists essentially from three areas, firstly the concavely curved Central area 2b, the outer area 2c with the crimping 2a and one Indoor area 2d.
- FIG. 6 shows a punched-out sheet metal part which corresponds to that in FIG. 5 shown reflector can be deformed.
- the two slots 12 in the interior 2d of the reflector which is easy to install of the reflector in the luminaire.
- two T-type are formed Retaining clips 11 are provided, which - as shown in FIGS. 1 and 3 - along the Middle of the bottom of the lamp housing 7 above the lamps 1 are attached.
- the present invention thus creates a lamp which has the same lighting properties as the known luminaire. Also the appearance of the lamp according to the invention essentially the same already known lamp, but the lamp according to the present Invention can be manufactured much easier and cheaper.
- the solution according to the invention of using two separate diffuser plates facilitates i.a. also the mounting of the plates in the luminaire housing.
