Description

SVETLOBNO TELO [0001] Predlagani izum se nanaša na svetlobno telo, zlasti na žaromet za vozilo, obsegajoče vir svetlobe, vsaj en reflektor, ki usmerja od vira svetlobe izhajajočo svetlobo, in vsaj en optični element, na primer lečo, ki zbira in posreduje z reflektorjem usmerjeno svetlobo želene oblike v želeno smer.The present invention relates to a light body, in particular to a headlamp for a vehicle comprising a light source, at least one reflector which directs the light emanating from the light source, and at least one optical element, for example a lens which collects and transmits reflector directed light of the desired shape in the desired direction.

[0002] Svetlobno telo, obsegajoče vir svetlobe, vsaj en reflektor in vsaj en optični element, je v splošnem znano. Pri tem vir svetlobe oddaja svetlobo, a je optični element, na primpr leča, zaradi svojih fizikalnih omejitev ne more izkoristiti v celoti. Posledično se del svetlobe izgubi, s čimer se zmanjša izkoristek med količino svetlobe, ki jo odda vir svetlobe, in količino svetlobe, ki zapusti optični element.A light body comprising a light source, at least one reflector and at least one optical element is generally known. In doing so, the light source emits light, but the optical element, for example the lens, cannot be fully utilized due to its physical limitations. As a result, some of the light is lost, reducing the efficiency between the amount of light emitted by the light source and the amount of light leaving the optical element.

[0003] Naloga predlaganega izuma je ustvariti svetlobno telo, s katerim so odpravljene pomanjkljivosti znane rešitve.The object of the present invention is to provide a light body which eliminates the disadvantages of the known solution.

[0004] Zastavljena naloga je po predlaganem izumu rešena z značilnostmi, podanimi v značilnostnem delu 1. patentnega zahtevka. Podrobnosti izuma so razkrite v pripadajočih podzahtevkih.The object set according to the present invention is solved by the characteristics given in the characteristic part 1 of the claim. Details of the invention are disclosed in the corresponding subclaims.

[0005] Izum je v nadaljevanju podrobneje predstavljen na osnovi ne omejujočega izvedbenega primera in s sklicevanjem na priložene skice, kjer kaže sl. 1 svetlobno telo po izumu v shematskem prečnem prerezu, sl. 2 izvedbeni primer svetlobnega telesa s sl. 1, sl. 3 drugi izvedbeni primer svetlobnega telesa s sl. 1.The invention is further presented in more detail on the basis of a non-limiting embodiment and with reference to the accompanying drawings, in which FIG. 1 shows a light body according to the invention in a schematic cross-section, FIG. 2 shows an embodiment of the light body of FIG. 1, fig. 3 shows another embodiment of the light body of FIG. 1.

[0006] Svetlobno telo po izumu obsega reflektor 1, vsaj en primarni optični element 2 in vsaj en vir 3 svetlobe. Omenjeni reflektor 1 je lahko bodisi enodelen ali večdelen, pri čemer je v slednjem primeru predeljen in združljiv v eni ali več ravninah, na primer v vodoravni in/ali navpični ravnini. Lijakasto zasnovanemu reflektorju 1 je na njegovem prvem, ožjem koncu priključen omenjeni vsaj en vir 3 svetlobe, ki seva svetlobo v celoten prostor pred seboj, to je +/- 90° v vodoravni smeri in +/- 90° v navpični smeri. Omenjeni vir 3 svetlobe je na primpr lahko izbran kot halogenski, ksenonski, laserski, LED izvor in podobno. Omenjeni reflektor 1 zbira in usmerja preostali del svetlobe, ki jo oddaja vir 3 svetlobe, v želeno smer in v želeni obliki. Pod preostali del svetlobe se pri tem razume tisti del svetlobe, izhajajoče iz vira 3, ki ga primarni optični element 2 zaradi svojih fizikalnih lastnosti oz. omejitev ne more usmeriti v želeno smer in v želeni obliki.The light body according to the invention comprises a reflector 1, at least one primary optical element 2 and at least one light source 3. Said reflector 1 may be either one-piece or multi-piece, in the latter case being partitioned and compatible in one or more planes, for example in the horizontal and / or vertical plane. Connected to the funnel-shaped reflector 1 at its first, narrower end is said at least one light source 3, which emits light into the entire space in front of it, i.e. +/- 90 ° in the horizontal direction and +/- 90 ° in the vertical direction. Said light source 3 can, for example, be selected as a halogen, xenon, laser, LED source and the like. Said reflector 1 collects and directs the remaining part of the light emitted by the light source 3 in the desired direction and in the desired shape. By the rest of the light is meant that part of the light emanating from the source 3, which the primary optical element 2 due to its physical properties or. the constraint cannot point in the desired direction and in the desired shape.

[0007] Omenjeni primarni optični element 2, ki je razporejen na drugem, širšem koncu reflektorja 1 in nasproti viru 3 svetlobe, usmerja del svetlobe, ki jo oddaja vir 3 svetlobe, v želeno smer in v želeni obliki. Primarni optični element 2 je izdelan iz za svetlobo prepustnega materiala, to je prozornega ali prosojnega materiala, na primer stekla, umetne snovi in podobnega. K viru 3 svetlobe obrnjena stran primarnega optičnega elementa 2 je zasnovana bodisi piano ali pa obsega v vsaj eni smeri svojega poteka, gledano ploskovno, vsaj dve območji, ki sta, gledano v prečnem prerezu, vsakokrat zasnovani v smislu odsekoma zvezne funkcije. Omenjeni primarni optični element 2 je lahko zasnovan v enem kosu, kot en sam integralen del z različnimi optičnimi lastnostmi, lahko pa je na po sebi znan način sestavljen iz več kosov, ki imajo različne optične lastnosti.Said primary optical element 2, which is arranged at the other, wider end of the reflector 1 and opposite the light source 3, directs a part of the light emitted by the light source 3 in the desired direction and in the desired shape. The primary optical element 2 is made of a light-transmitting material, i.e. a transparent or translucent material such as glass, plastic and the like. The light source side 3 of the primary optical element 2 is designed either piano or comprises in at least one direction of its course, viewed planarly, at least two areas, which, viewed in cross section, are each designed in terms of sections of a continuous function. Said primary optical element 2 may be designed in one piece, as a single integral part with different optical properties, or it may in a known manner consist of several pieces having different optical properties.

[0008] Dalje je po predlaganem izumu predvideno, daje omenjeni primarni optični element 2 v območju svojega zunanjega roba 2’, ležečega v soseščini reflektorja 1, izbiroma vsaj odsekoma zasnovan z vsaj enim dodatnim optičnim elementom 4, ki je izdelan iz za svetlobo prepustnega materiala, to je prozornega ah prosojnega materiala, na primer stekla, umetne snovi in podobnega. Omenjeni dodatni optični element 4 je lahko bodisi integralni del primarnega optičnega elementa 2 ali pa je s primarnim optičnim elementom 2 povezan na odstranljiv način. V primeru, ko je dodatni optični element 4 s primarnim optičnim elementom 2 povezan na odstranljiv način, je mogoča tudi izvedba žarometa vozila, pri kateri je omenjeni dodatni optični element 4 odsoten.Furthermore, according to the present invention, it is provided that said primary optical element 2 in the area of its outer edge 2 'lying in the neighborhood of the reflector 1 is optionally designed with at least one additional optical element 4 made of light-transmitting material. , it is a transparent ah transparent material, such as glass, plastic and the like. Said additional optical element 4 may either be an integral part of the primary optical element 2 or be connected to the primary optical element 2 in a removable manner. In the case where the additional optical element 4 is connected to the primary optical element 2 in a removable manner, it is also possible to make a vehicle headlight in which said additional optical element 4 is absent.

[0009] Omenjeni vir 3 svetlobe v celotnem obsegu 5 oddaja svetlobo v smeri od omenjenega ožjega dela reflektorja 1 proti omenjenemu širšemu delu reflektorja 1. Omenjeni optični element 2 zaradi svojih fizikalnih lastnosti in omejitev lahko izkoristi le ožji obseg 6 svetlobe omenjenega celotnega obsega 5. Posledično se preostali obseg 7’, 7” svetlobe, ki jo oddaja vir 3 svetlobe in jo reflektor 1 usmerja, izgubi. Da se prepreči omenjeno izgubo omenjenega obsega 7’, 7” svetlobe, je omenjeni primarni optični element 2 v območju svojega zunanjega roba 2’, ležečega v soseščini reflektorja 1, izbiroma vsaj odsekoma zasnovan z vsaj enim dodatnim optičnim elementom 4. Omenjeni vsaj en dodatni optični element 4 vpliva na svetlobni obseg 7’, 7” na način, da vpliva na smer poteka svetlobe in/ali obliko le-te.Said light source 3 in the entire range 5 emits light in the direction from said narrower part of the reflector 1 towards said wider part of the reflector 1. Said optical element 2 due to its physical properties and limitations can only use the narrower light range 6 of said total range 5. As a result, the remaining range 7 ', 7 ”of light emitted by the light source 3 and directed by the reflector 1 is lost. To prevent said loss of said range 7 ', 7 ”of light, said primary optical element 2 in the region of its outer edge 2' lying in the neighborhood of the reflector 1 is optionally designed at least in sections with at least one additional optical element 4. Said at least one additional the optical element 4 influences the light range 7 ', 7 ”in such a way as to influence the direction of light flow and / or the shape thereof.

[0010] Omenjeni primarni optični element 2 je zasnovan na način, da s pomočjo svetlobnega obsega 5 po potrebi oblikuje svetlo-temno mejo žarometa vozila, kar pomeni, da je nad svetlo-temno mejo svetloba bodisi prisotna ali odsotna. Omenjeni reflektor 1 usmeri svetlobni obseg 7’, 7” skozi omenjeni dodatni optični element 4 na način, da lahko tvori dodamo svetlo-temno mejo žarometa vozila, ki leži nad ali pod svetlo-temno mejo, ki jo tvori primarni optični element 2, ali leži na svetlo-temni meji, ki jo tvori primarni optični element 2. Predvidena je tudi možnost, da svetlo-temna meja primarnega optičnega elementa 2 sovpada z dodamo svetlo-temno mejo dodatnega optičnega elementa 4. Še dodatna možnost predvideva, da je dodatna svetlo-temna meja odsotna, dodatni optični element 4 pa svetlobni obseg 7’, 7” preusmeri na želeno območje z želeno porazdelitvijo svetlobe.Said primary optical element 2 is designed to form a light-dark border of the vehicle headlight, if necessary, by means of a light range 5, which means that light is either present or absent above the light-dark limit. Said reflector 1 directs the light range 7 ', 7 ”through said additional optical element 4 in such a way that a light-dark border of the vehicle headlamp lying above or below the light-dark limit formed by the primary optical element 2 can be formed, or lies on the light-dark boundary formed by the primary optical element 2. It is also possible for the light-dark boundary of the primary optical element 2 to coincide with the addition of the light-dark boundary of the additional optical element 4. The additional option assumes that the additional light -dark border absent, and the additional optical element 4 redirects the light range 7 ', 7 ”to the desired area with the desired light distribution.
