The invention concerns a shining object, which exhibits at least a shining means, which is mittens conductor connected with a power source or connectable. RST the available invention has the goal of manufacturing on simple and kosteng0nstige way of shining objects with which the shining means in the shining body is integrated and which can withdraw light at gew0nschten places or Flincher of the shining object. The form of such shining objects softly at will gew to be ihlt k0nnen, since they occur in vielf iltigen areas of application. The shining objects k6nnen flat like a plate its, like e.g. signs of all art. a special area of application yon shining objects w ren lit signs such as KFZ Nummerntafeln and such a thing. It can be also worthwhile to equip the shining objects with light of different colors. Indicated by the light k6nnen in or at the shining object writings, flat steel bar chen colored or weird to be lit up or it soil the entire K6rper be illuminated. Areas of application for shining objects are beside the KFZ Nummemtafeln for vehicles also signs, advertising boards, lighting parts in the automotive manufacture, go use from electrical Ger ten, Bilderrahmen, UhrgehSuse or Armb= more nder, safety products like e.g. Wamdreiecke, Schult ashes or escape route safety devices. Illuminably also keys or Geh= use of elektmnischen Ger= wren ten, in addition, clothe-come to a hold or shoes. This AufzShlung is only exemplary and it hardly gives for the areas of application a Beschr nkung. However it was so far not m0glich to use these vielf ltigen areas of application since either the shining means one then vielf Utige use in also d0nnen shining objects not zuliel EN, or because the installation of shining means was into the shining objects expensive or complex. With the available invention the above disadvantages are avoided. oo oo oo oooo oo • • oo • • • • • ge o. - oo oo • o Oo. 2 46214 Schoenberg Elumic GmbH. , f the available invention is primarily cladurch characterized that the shining object is a shining body made of plastic, into which the shining means melted. After further characteristics of the invention the shining means is several in series or parallel switched LEDs, which is arranged on a conductor. The conductor can be zweioder more driges flat cable, on or between whose conductive strips the LEDs fastened and contacted are. After a further characteristic of the invention the shining means at least partly melted into the Leuchtk0rper from thermoplastic plastic by means of injection moulding. The shining characteristics of the shining objects affected by several mark took. On the one hand the arrangement of the shining means is important within the Leuchtk rpers. This arrangement determines, from which places the light into the Leuchtk0rper delivered win: l, whereby the areas of the arrangement of the shining means of one only nkten beschr mechanical and thermal shaping untediegen dOrfen. The choice of the LED determines the kind and color of the sent light. The further mark to the shaping of the shining body and the mark took the Oberfl chengestaltung affect in further consequence the path of rays of the light and the entire photometric characteristics of the shining object took. For example the Oberfl che of the Leuchtk0rpers can light-faithful-end light-taking off layers or Oberfi with reflecting, reflecting, and/or ichengestaltungen to be provided. The Leuchtk0rper can do light-steering or light-faithful-ends EinschlQsse to contain. Inhere details to this different Ausf0hrungen are geoffenbart far down description of the invention iheren in the n. Figures 1, 2 and 3 show cuts through invention in accordance with e of shining objects in different AusfOhrungsformen. Figure 4 shows a L ingsschnitt by a shining object in form of a vehicle characteristic board and a figure 5 shows the supervision to this board. 46214 Schoenberg Elumic GmbH the figures 1 and 2 demonstrate, like the shining means in a Leuchtk0rper made of plastic embedded its k6nnen. The form of the shining object is here a rectangular plate, which is cut off in the design down in each case and is represented in the cross section. The form of the shining object is nkt however not on this simple form beschr, but can represent any form of an object e.g. also kugelf6rmig or unregelmSl industrial union. In accordance with IL invention can be lit up each three-dimensional form of a shining object. In accordance with ll figure 1 the shining object covers a Leuchtk0rper 1 from transparent or transparent plastic. Into the Leuchtk0rper 1 the shining means 2 melted. The shining means consists a conductor of a 3, on which are one behind the other as source of light LED 4 located. The conductor consists in this AusfQhrungsbeispiel of two drigen flat cables. Through actually admitted methods of handling such as stamping machines or. Laserbearbeitung k0nnen the line courses 14 of the current leader in the suitable places to be interrupted and by means of likewise well-known mounting techniques the LEDs to the 0berbr0ckung be aufgelbtet. In addition, the conductor with the LEDs from cables with herk5mmlicher mounting technique can be designed or as strips of a printed circuit, on which the LEDs aufgel0tet become. The lung of the shining means h ngt amplifiers ndlich of that gew0nschten Linger of the lighting and the of that kind of the Leuchtk6rpers off. In figure 1 the shining means 2 melted to the GSnze and from there generally from the Leuchtk6rper 1 enclosed. In the Ausf0hrungsbeispiel in accordance with l figure 2 sits the shining means 2 along one the Flincher of the shining object, whereby the Leuchtk0rper 1 melted only on that side of the shining means, at which the LEDs sits. Yon are suggested to the LEDs radiated rays of light with the reference symbol. i oo t, • •; • • • • • ° •. • ° • • • ° • o • •, '•, '• • •; o • • • o • • • • • 4 46214 Schoenberg Elumic GmbH around the light withdrawal of the light in gewi nschtem, radiated from the shining means 2, paint to affect, is the Leuchtk6rper 1 with appropriate Oberfl chen provided. The top margin and the right Fiche are provided with a mirror layer 6, which the rays of light of the Oberfl tchen into the shining body 1 zurScklenkt. Thus it is prevented that light energy is wasted and it withdraws light, woes gewi only there is nscht. In figure 1 the Vorderfl che 7 is simple the Begrenzungsfl iche of the Leuchtk0rpers. There thus the light withdraws unhindered and radiates from the Leuchtk0rper after 1 vome. In figure 2 the Vorderfl che 7 provided with a diffusion layer 8 is, in order to steer the light withdrawal by the Vordeffl che 7 in the gewQnschten mark. This is diffusion layer 8 can e.g. be a reflecting or the rays of light at least partial ckstrahlende layer, which is tssig made by rasterf0rmige Aufbdngung purposefully teildurchl. The light withdrawal can be steered also by the DOnnheit of the layer or by the applied material or Oberfi chengestaltung like e.g. Aufrauen. Different flat steel bars ichenabschnitte k0nnen different radiation characteristics and different F irbung exhibit. The figure 3 shows 9 and zus tzlich Einpr to the RQckseite a reflection layer igungen or grooves 10, which serve to radiate the light radiated from the LEDs 4 to the gew0nschten after places vome toward 7 iche to the Vorderfi. Instead of the grooves also Brechungsk0rper can be arranged, which has a refractive index, which is different of that one of the Leuchtk6rpermaterials 1. With the r0ckseitigen silvering and arrangement yon Brechungsk6rpem or grooves is it m0glich, which widens light in the shining body also uleiten if the Leuchtk0rper is three-dimensional curved, as this is for example with gepr gten Leuchtschildem the case. In the AusfOhrungsbeispiel after figure 3 a diffusion layer 8 is intended and these is likewise placed in front a retroflecting layer 11, which serves for it, e.g. with traffic signs or Fahrzeugkennzeichenee QQ • ° to the Vorderfl che 7; o °,% • °, 'o° %° • °° 46214 Schoenberg Elumic GmbH boards the hitting foreign light in an appropriate way zur0ckzustrahlen, whereby a R0ckstrahleffekt develops. A Leuchtk6rper in form one shows 4 the figure 4 very d0nnen plate, like it e.g. for vehicle characteristic boards to the Progeny of the characteristic numbers to be planned knows. DerarUge boards are for instance 1-2mm thickly. In the cross section the arrangement corresponds about to that one the figure 3. the StSrke of the Leuchtk0rpers must be so limited that the LEDs 4 find along the streifenf6rmigen of shining means place, so that the LEDs melted completely in the Leuchtk0rper. In figure 4 also the nachtrSglich pressed in PrSgungen in the range of the letters and Ziffem of the characteristic board is to be seen. AIs schwa e bar are drawn in the laid on letters and numbers 12 gungen on the Pr. The streifenf6rmige shining means 2 is arranged along the upper edge 13 of the shining object and the positions of the LED is suggested with crosses. Self amplifiers ndlich kbnnen instead of a streifenf0rmigen of the shining means also several shining means in the Leuchtk0rper melted its, around one vollst ndige illuminating too gew ihdeisten. The LEDs k0nnen verschiedenf irbig and individually headed for its, whereby light effects are producible and verschiedenf rbig lit up fish. Verschiedenf irbige control can represent e.g. different BetriebszustSnde, what for example with lit control panels can be important. Invention in accordance with l EN of shining objects k6nnen also the recesses appropriate to the OberflSche with controls such as keys to be provided or it be able dutch the Leuchtk0rper to be through planned, in order to arrange key fields or single keys, in order to permit an operation. For the production erfindungsgemSl of the EN of shining objects is very favourably the M0glichkeit to use the technology of the Hinterspritzens. The shining means is inserted in prefabricated form into an injection mold and injected after SchlieBen of the form the injection moulding plastic. AIs injection moulding material is suitable each plastic material, which is fShig at zul the issigen temperatures fliel enough, around the shining means with melt for umh011en. Further the injection moulding plastic must exhibit the necessary characteristics of the shining body after the ErhSrten, like e.g. n0tige transparency and Lichtleiff ihigkeit within the Leuchtk6rpers. Oo oo a O00o 6 preferential material is polycarbonate plastic. Plastic is PC Tarflon IR 1700 highly transparently. 46214 Schoenberg Elumic GmbH an example f0r such the material for the Kabelk6rper, which surrounds the conductive strips 14 in an isolated manner, soil prefers compatibly with the injection moulding material for the Leuchtk6rper its. An example f0r such material is TPU, which has very good connecting characteristics with polycarbonate. It understands itself automatically that the temperatures for the Hinterspritzungsvorgang the injection moulding material adapted its m0ssen, whereby the temperatures also for the LEDs 4 and the cable body 15 vertrSglich its m0ssen lies, with melted polycarbonate the temperature for instance between 290°C and 320°C. Advantages invention in accordance with IR EN of the shining objects are also in the fact that the sources of light have a high life span that arbitrary colors are hlt gew k6nnen and that the sources of light are inseparably connected with the shining object, so that they are before unenN0nschten manipulations gesch0tzt. Further these have a small current consumption invention in accordance with l EN of shining objects with high EffektivitSt. Such shining objects k0nnen also in places to be used, which are otherwise only with difficulty course inglich. The replacement of L are n6tig and also not m6glich do not impchen, so that the shining objects not zugSnglich its m (Jssen. By the Eingiel EN of the LED in plastic bodies the common mechanical firmness is much gml and a loss by mechanical loads, e.g. in the case of transport, nearly unm0glich. This is substantial advantage and 0berraschend, because manufacturers from electronic parts to today with many complaints by Fr0hausf ille mpfen like interruption the LED contact points to k have. Depending upon Gr61 e of the Kunststoffk0rpers and the ben6tigten electronics it can be, also favourably also electronics into the Kunststoffk0rper in the injection moulding einzuschliel EN. The power connection f0r the shining means takes place best via the fact that the shining means with its conductive strips from the Leuchtk0rper is herausgefQhrt and the end of the current leader is provided with a plug. °oo° 46214 Schoenberg Elumic GmbH the coatings of the shining object can be applied for example by painting, coating or 8hnliche procedure. FOr the Hinterspritzen are lltlich appropriate foils erh, on which the plastic spraying material can be sprayed on. The two-color injection moulding technology is likewise well suitable, in order to create lichffOhrende, reflecting, strewing or reflecting zones by different plastics. Further it can be favourable to manufacture the Oberfl che of the Leuchtk0rpem with a colour foil and/or with a foil already printed on in “in mould decoration” the procedure. Thus can the Oberfl ichen decoratively to be arranged, including the arrangement of the shining means. At the same time k0nnen the reflection layers and/or delimitation layers with the same injection moulding procedure to be arranged. The grooves 10 k0nnen different forms have like e.g. pyramid, Kugeloder Kegelform. In order to adjust the reduction of the brightness with the distance to the source of light, it can be favourable to let with increasing distance of the source of light the number of reflecting grooves increase so that on the respective view side of the shining object an m l ige brightness appears. In the close range to the source of light it can be however favourable to dip the headlights a too high Lichtintensit it. 4 the Kabelk more rper it can be arranged in such a way in the Leuchtk0rper that he works as screen. eQ Qe QQ Qeee eQ 6 Q Q • Q Q Q • • 6 46214 Schoenberg Elumic GmbH I
