Svetilo motornega vozilaMotor vehicle light

Izum spada na področje transporta, konkretno k svetlobni opremi za vozila, namreč k svetilom za motorna vozila, še zlasti k svetilom, ki so prvenstveno predvidena kot signalizacij ska svetila za označevanje vozila ali njegovih delov ali za označevanje spremembe smeri vožnje vozila.The invention relates to the field of transport, in particular to vehicle lighting equipment, namely motor vehicle lamps, and in particular to lamps primarily intended as signaling lamps for marking the vehicle or its parts or for marking a change in the direction of travel of the vehicle.

Pri tem je izum osnovan na problemu, kako zasnovati preprosto, iz majhnega števila za izdelavo karseda preprostih sestavnih delov sestoječe svetilo s karseda majhnimi dimenzijami, še zlasti dimenzijo v smeri optične osi, t.j. globino svetila v smeri izstopanja svetlobe v okolico svetila, pri čemer naj bi bilo svetilo zmožno oddajati motno difuzno svetlobo po celotni navzven vidni površini leče enakomerne jakosti ter brez ostrih kontrastnih prehodov in/ali bleščanja.The invention is based on the problem of how to design a simple, small number of lamps with as many simple components as possible, with as small a dimension as possible, in particular a dimension in the optical axis, i.e. the depth of the luminaire in the direction of the light exiting the luminaire, whereby the luminaire is capable of transmitting cloudy diffuse light over the entire outwardly visible surface of the lens of uniform intensity and without sharp contrast transitions and / or glare.

Svetilo za motorna vozila je opisano v EP 0 990 838 A2 in obsega izvor svetlobe, ki je obdan s cevastim reflektorjem, ki je na enem koncu v območju svetila parabolično zaključen, na preostalem koncu pa poševno prirezan. Leča sestoji iz rastra elementov za preusmerjanje žarkov v vertikalni smeri in elementov za preusmerjanje žarkov v horizontalni smeri, namen svetila pa je zagotoviti homogeno porazdelitev iz svetila izstopajočih žarkov ne glede na dejstvo, da je reflektor poševno prirezan zaradi ukrivljenosti karoserije motornega vozila. Žarki, generirani v izvoru svetlobe, se od refleksijske površine reflektorja odbijajo pod različnimi koti in torej med seboj niso vzporedni, vendar pa je iz tovrstnega svetila izstopajoča svetloba po jakosti vsaj približno enakomerno porazdeljena po celotni navzven vidni površini leče svetila. Ne glede na to pa pri praktični uporabi tovrstnega svetila delujoče svetilo od zunaj še vedno daje videz nehomogenega rastra oz. množice svetlih točk, med katerimi so še vedno prisotna neznatna manj osvetljena območja. Po drugi strani je zaradi cevaste zasnove svetila dimenzija v optični smeri znatno večja od samega premera cevastega reflektorja, kar lahko v praksi bodisi iz stilističnih razlogov ali pa že zgolj zaradi prostorskih omejitev prepreči možnost vgradnje tovrstnega svetila vsaj na določene lokacije v vozilu.The motor vehicle luminaire is described in EP 0 990 838 A2 and comprises a light source surrounded by a tubular reflector which is parabolic terminated at one end in the area of the luminaire and obliquely trimmed at the other end. The lens consists of a grid of elements for beam diversion in the vertical direction and elements for beam diversion in the horizontal direction. The rays generated at the light source reflect at different angles from the reflecting surface of the reflector and thus are not parallel to each other, but the light emanating from such light is at least approximately evenly distributed over the entire outwardly visible surface of the lens of the lamp. Nevertheless, when using this kind of light, the active light from the outside still gives the appearance of a non-homogeneous screen. many bright spots, some of which still have slightly less illuminated areas. On the other hand, due to the tubular design of the lamp, the dimension in the optical direction is significantly larger than the diameter of the tubular reflector, which in practice, either for stylistic reasons or simply due to space constraints, prevents the possibility of mounting such a lamp at least at certain locations in the vehicle.

Izum se nanaša na svetilo motornega vozila, kakršno obsega ohišje, ki je po obliki in dimenzijah prirejeno za vgradnjo v karoserijo, odbijač, vzvratno ogledalo ali drug del motornega vozila. Poleg omenjenega ohišja svetilo nadalje obsega vsaj en izvor svetlobe, še zlasti LED, ki je primeren za generiranje svetlobnih žarkov, nadalje vsaj eno refleksijsko površino, ki je prirejena za preusmerjanje omenjenih svetlobnih žarkov v obliki snopa med seboj vzporednih žarkov v smeri izstopanja iz svetila, kot tudi za svetlobo prepustno lečo, ki je primerna za prehod omenjenih svetlobnih žarkov in izstopanje le-teh iz svetila v vsakokrat za osvetljevanje predvideno območje izven vsakokratnega motornega vozila. Pri tem je vsakokrat izbran položaj omenjenega izvora svetlobe definiran z osrednjo geometrijsko osjo omenjenega izvora svetlobe, položaj samega svetila pa z optično osjo svetila, ki sovpada s smerjo poteka na omenjeni refleksijski površini odbitih svetlobnih žarkov v smeri proti omenjeni leči.The invention relates to a motor vehicle luminaire comprising a housing which is adapted in shape and dimensions for installation in a bodywork, bumper, rear view mirror or other part of a motor vehicle. In addition to said housing, the lamp further comprises at least one light source, in particular an LED suitable for generating light rays, further comprising at least one reflecting surface adapted to divert the said light rays in the form of a beam of parallel rays in the direction of exit from the lamp, as well as a light-transmitting lens, which is suitable for the passage of said light beams and their exit from the lamp into the area provided for illumination outside the motor vehicle in question. In this case, the selected position of said light source is defined by the central geometric axis of said light source, and the position of the light itself by the optical axis of the light coinciding with the direction passing on said reflection surface of the reflected light rays in the direction towards said lens.

Svetilo po izumu se odlikuje po tem, da je na proti omenjeni refleksijski površini obrnjeni strani omenjene leče predvidena difuzna plast, ki je razporejena neposredno ob omenjeni leči in v neposrednem stiku z le-to, in sicer brez vsakršne zračnosti med njima, tako da od izvora svetlobe prihajajoči in na refleksijski površini preusmerjeni svetlobni žarki pred prehodom skozi lečo prehajajo skozi omenjeno difuzno plast. Obenem je v območju med izvorom svetlobe in omenjeno difuzno plastjo predviden za svetlobo neprepusten zaslon za preprečevanje prehoda svetlobnih žarkov od omenjenega izvora svetlobe neposredno proti omenjeni difuzni plasti oz. leči, tako da je prehod skozi omenjeno difuzno plast in zatem skozi lečo omogočen samo tistim žarkom, ki so na omenjeni refleksijski površini preusmerjeni v snop med seboj vzporednih svetlobnih žarkov. Hkrati pa tudi geometrijska os izvora svetlobe poteka vsaj približno v smeri prečno glede na omenjeno optično os svetila, pri čemer je pri prednostni izvedbi izuma je geometrijska os izvora svetlobe razporejena vsaj približno pravokotno glede na omenjeno optično os svetila.The light according to the invention is characterized in that a diffusive layer is arranged on the reflective surface facing the said lens, which is arranged directly adjacent to and in direct contact with said lens without any clearance between them, so that light sources, incoming and redirected light rays passing through said diffuse layer before passing through the lens. At the same time, a light-tight screen is provided in the area between the light source and said diffuse layer to prevent the passage of light rays from said light source directly towards said diffuse layer or light diffuser. lenses so that passage through said diffuse layer and then through the lens is only possible to those rays which are directed to the beam of parallel light rays on said reflection surface. At the same time, the geometric axis of the light source extends at least approximately in the transverse direction with respect to said optical axis of the light, wherein in a preferred embodiment of the invention the geometric axis of the light source is arranged at least approximately orthogonal to said optical axis of the light.

Pri eni od možnih izvedb izuma omenjena difuzna plast sestoji iz za svetlobo prepustnega materiala z vgrajenimi naključno razporejenimi refleksijskimi delci iz drugačnega, za svetlobo neprepustnega materiala.In one of the possible embodiments of the invention, said diffuse layer consists of a light-permeable material with embedded randomly arranged reflection particles of a different light-impermeable material.

Pri nadaljnji možni izvedbi izuma omenjena difuzna plast sestoji iz za svetlobo prepustnega materiala z vgrajenimi naključno razporejenimi refleksijskimi delci iz drugačnega, za svetlobo vsaj deloma prepustnega materiala.In a further possible embodiment of the invention, said diffuse layer consists of a light-transmitting material with embedded randomly arranged reflection particles of a different light-transmitting material, at least in part.

Po izumu je nadalje predvideno, da po eni strani omenjena difuzna plast sestoji iz termoplastičnega polimernega materiala, v katerem so vgrajeni mikrodelci, po drugi strani pa tudi omenjena leča sestoji iz termoplastičnega polimernega materiala, ker je na ta način omenjena difuzna plast lahko izvedena enovito z omenjeno lečo, in sicer še zlasti s pomočjo dvokomponentnega brizganja termoplastičnih materialov difuzne plasti in leče v primernem orodju za preoblikovanje polimernih termoplastičnih mas.According to the invention, it is further provided that on the one hand said diffuse layer consists of a thermoplastic polymer material in which microparticles are embedded, and on the other hand, said lens consists of a thermoplastic polymeric material, since in this way said diffuse layer can be made uniformly with said lens, in particular by means of a two-component injection molding of the thermoplastic materials of the diffusion layer and the lens in a suitable tool for the transformation of polymer thermoplastic masses.

Po izumu je nadalje prednostno, če je omenjena refleksijska površina razporejena kar na notranji površini samega ohišja svetila.According to the invention, it is further preferred that said reflecting surface is disposed directly on the inner surface of the lamp housing itself.

Po izumu je še nadalje prednostno, če je za svetlobo neprepusten zaslon izveden enovito z ohišjem oz. predstavlja integralni del omenjenega ohišja.According to the invention, it is still preferable if the light-tight screen is made uniformly with the housing or housing. represents an integral part of said housing.

Izum bo v nadaljevanju podrobneje opisan na osnovi primera izvedbe in v skladu s priloženo skico, kjer kažejoThe invention will now be described in further detail based on the embodiment and in accordance with the accompanying drawing, where they are shown

Sl. 1 svetilo motornega vozila v vgrajenem stanju;FIG. 1 motor vehicle lamp in the installed state;

Sl. 2 svetilo v prečnem prerezu v ravnini A - A po Sl. 1;FIG. 2 is a cross-sectional view in plane A - A of FIG. 1;

Sl. 3 izometrično ponazoritev svetila v vgrajenem stanju;FIG. 3 isometric illustration of the lamp when installed;

Sl. 4 pa shematično ponazorjen potek svetlobnih žarkov skozi svetilo po izumu.FIG. 4 is a schematic illustration of the flow of light rays through a light according to the invention.

Svetilo motornega vozila po Sl. 1-4, obsega ohišje 1, ki je po obliki in dimenzijah prirejeno za vgradnjo v karoserijo, odbijač, vzvratno ogledalo ali drug del motornega vozila V. Svetilo nadalje obsega vsaj en izvor 2 svetlobe, ki je v konkretnem primeru LED (strokovnjakom znana okrajšava za Light Emmitting Diode) in ki je predvideno za generiranje svetlobnih žarkov, ki jih potem svetilo oddaja v vnaprej določeno območje v okolici motornega vozila.Motor vehicle illumination according to FIG. 1-4, comprises a housing 1 adapted for shape and dimensions for bodywork, bumper, rearview mirror or other part of a motor vehicle V. The lamp further comprises at least one light source 2, which in this particular case is an LED (known to the skilled person) for Light Emmitting Diode) and which is intended to generate light beams which are then emitted by the lamp into a predetermined area around the motor vehicle.

Svetilo nadalje obsega vsaj eno refleksijsko površino 3, ki je prirejena za preusmerjanje od omenjenega izvora 2 svetlobe sprejetih omenjenih svetlobnih žarkov, in sicer v obliki snopa med seboj vzporednih žarkov (Sl. 4) v smeri izstopanja iz svetila.The lamp further comprises at least one reflecting surface 3 adapted to divert from the light source 2 received from said light beams, in the form of a beam of parallel beams (Fig. 4) in the direction of exit from the lamp.

Še nadalje svetilo po Sl. 1 - 4 obsega za svetlobo prepustno lečo 4, ki je primerna za prehod omenjenih svetlobnih žarkov in izstopanje le-teh iz svetila v že omenjeno, vsakokrat za osvetljevanje predvideno območje izven vsakokratnega motornega vozila.A further illumination according to FIG. 1 to 4 comprises a light transmittable lens 4 which is suitable for the passage of said light rays and for exiting them from the lamp into the aforementioned area outside the respective motor vehicle for each illumination.

Pri tem je vsakokrat izbran položaj omenjenega izvora svetlobe 2 definiran z osrednjo geometrijsko osjo 20 omenjenega izvora 2 svetlobe, ki v danem primeru izvedbe predstavlja vzdolžno centralno os LED, ki obenem predstavlja središče oddajanja svetlobnih žarkov.In each case, the selected position of said light source 2 is defined by the central geometric axis 20 of said light source 2, which in the present embodiment represents the longitudinal central axis of the LED, which at the same time represents the center of light emission.

Po drugi strani je položaj vgradnje samega svetila v vsakokraten del motornega vozila V definiran z optično osjo 10 svetila, ki sovpada s smerjo poteka na omenjeni refleksijski površini 3 odbitih svetlobnih žarkov v smeri proti omenjeni leči 4 in v splošnem, kot je strokovnjakom s tega področja znano, ustreza smeri izstopanja svetlobnih žarkov iz svetila.On the other hand, the position of installation of the lamp itself in each part of the motor vehicle V is defined by the optical axis 10 of the lamp, which coincides with the direction passing on said reflecting surface 3 of the reflected light rays in the direction of said lens 4 and, in general, to those skilled in the art. known to correspond to the direction of exit of light rays from the lamp.

Razen tega je pri svetilu po izumu na tisti strani leče 4, ki je obrnjena proti omenjeni refleksijski površini 3, predvidena difuzna plast 5, ki je razporejena neposredno ob omenjeni leči 4 in v neposrednem stiku z le-to, torej brez vsakršne zračnosti med njima. Zahvaljujoč tovrstni razporeditvi omenjene difuzne plasti 5 in leče 4 potem od izvora 2 svetlobe prihajajoči in na refleksijski površini 3 preusmerjeni svetlobni žarki še pred prehodom skozi lečo 4 in potem ven z svetila prehajajo skozi omenjeno difuzno plast 5. Pri prednostni izvedbi izuma je refleksijska površina 3 razporejena na notranji površini samega ohišja 1 svetila.In addition, in the light according to the invention, on the other side of the lens 4 facing the said reflecting surface 3, a diffusion layer 5 is provided, which is arranged directly adjacent to said lens 4 and in direct contact with it, ie without any clearance between them. . Due to this arrangement of said diffuse layer 5 and lens 4, the light rays from the light source 2 and the light rays diverted before passing through the lens 4 and then passing through the diffuse layer 5 from the lamps. In a preferred embodiment of the invention, the reflection surface 3 arranged on the inner surface of the lamp housing itself.

Omenjena difuzna plast 5 lahko po izbiri sestoji iz za svetlobo prepustnega materiala z vgrajenimi naključno razporejenimi refleksijskimi delci iz drugačnega, za svetlobo neprepustnega materiala, ali pa iz za svetlobo prepustnega materiala z vgrajenimi naključno razporejenimi refleksijskimi delci iz drugačnega, za svetlobo vsaj deloma prepustnega materiala. Zaradi prisotnost omenjenih delcev v materialu difuzne plasti 5 namreč pride do vizualno popolnoma enakomerne razpršitve svetlobnih žarkov v različne smeri še pred vstopanjem le-teh v lečo 4 in zatem ven iz svetila, kar potem generira motno difuzno svetlobo po celotni navzven vidni površini leče, pri čemer gre za svetlobo enakomerne jakosti ter brez ostrih kontrastnih prehodov in/ali bleščanja.Said diffusion layer 5 may optionally consist of a light-transmitting material with incidentally arranged reflective particles of a different light-impermeable material, or of a light-transmitting material having a randomly arranged reflective particles of different, at least partially translucent material. Due to the presence of said particles in the material of diffuse layer 5, there is a visually uniform dispersion of light rays in different directions even before they enter the lens 4 and then out of the lamp, which then generates cloudy diffuse light across the entire outward visible surface of the lens, which is a light of even intensity and without sharp contrast transitions and / or glare.

Po izumu je še zlasti prednostno, če po eni strani omenjena difuzna plast 5 sestoji iz termoplastičnega polimernega materiala, v katerem so vgrajeni mikrodelci, in če po drugi strani tudi leča 4 sestoji iz termoplastičnega polimernega materiala. V takem primeru je lahko omenjena difuzna plast 5 izvedena enovito z omenjeno lečo 4 na razmeroma preprost in cenen način s pomočjo strokovnjakom znanega dvokomponentnega brizganja termoplastičnih materialov difuzne plasti 5 in leče 4 v primernem orodju, pri katerem se v orodju najprej formira lečo 4 in zatem še plast 5, ali pa obratno.According to the invention, it is particularly advantageous if, on the one hand, said diffuse layer 5 consists of a thermoplastic polymer material in which the microparticles are embedded and, on the other, the lens 4 also consists of a thermoplastic polymer material. In such a case, said diffuse layer 5 can be made uniformly with said lens 4 in a relatively simple and inexpensive manner by the skilled artisan of the two-component injection molding of thermoplastic materials of diffuse layer 5 and lens 4 in a suitable tool, in which the lens 4 is formed first and thereafter another layer 5, or vice versa.

Za nemoteno delovanje svetila po izumu pa je potrebno nadalje tudi zagotoviti, daje v območju med izvorom 2 svetlobe in omenjeno difuzno plastjo 5 na voljo za svetlobo neprepusten zaslon 6, ki preprečuje prehod svetlobnih žarkov od izvora 2 svetlobe neposredno proti omenjeni difuzni plasti 5 oz. leči 4. Temu ustrezno je prehod skozi omenjeno difuzno plast 5 in zatem skozi lečo 4 omogočen samo tistim žarkom, ki so na omenjeni refleksijski površini 3 preusmerjeni v snop med seboj vzporednih svetlobnih žarkov (Sl. 4). Pri prednostni izvedbi izuma je omenjen za svetlobo neprepusten zaslon 6 izveden enovito z ohišjem 1 oz. predstavlja integralni del omenjenega ohišja 1.For the smooth operation of the lamp according to the invention, it is further necessary to ensure that a light-tight screen 6 is provided in the area between the light source 2 and said diffuse layer 5, which prevents the passage of light rays from the light source 2 directly towards said diffuse layer 5 or. Accordingly, the passage through said diffuse layer 5, and subsequently through the lens 4, is enabled only by those rays which, on said reflection surface 3, are directed into a beam of parallel light rays (Fig. 4). In a preferred embodiment of the invention, said light-tight screen 6 is made uniformly with housing 1 or. represents an integral part of said housing 1.

Kot je razvidno na Sl. 1 - 3, geometrijska os 20 izvora 2 svetlobe poteka vsaj približno v smeri prečno glede na omenjeno optično os 10 svetila in je prednostno razporejena vsaj približno pravokotno glede na omenjeno optično os 10 svetila. S tem je po eni strani zagotovljen ugoden potek svetlobnih žarkov od izvora 2 svetlobe mimo zaslona 6 do refleksijske površine 3 ter zatem skozi difuzno plast 5 in lečo 4 ven iz svetila, po drugi strani pa tovrsten koncept omogoča tudi znatno zmanjšanje dimenzije svetila v smeri optične osi, t.j. globino svetila, ki s tem postane popolnoma neobsežno in dopušča neproblematično vgradnjo v različne dele motornega vozila.As can be seen in FIG. 1 to 3, the geometric axis 20 of the light source 2 extends at least approximately transversely with respect to said optical axis 10 of the lamp and is preferably arranged at least approximately orthogonal to said optical axis 10 of the lamp. This, on the one hand, provides a favorable course of light rays from the light source 2 past the screen 6 to the reflecting surface 3 and then through the diffuse layer 5 and the lens 4 out of the lamp, and on the other hand, this concept also allows a significant reduction of the optical dimension in the optical direction axis, ie the depth of the lamp, which thus becomes completely immense and permits easy installation in different parts of the motor vehicle.

vozila majhnih dimenzij, še zlasti z razmeroma majhno dimenzijo v smeri optične osi, t.j. globino svetila v smeri izstopanja svetlobe v okolico svetila, pri čemer je svetilo zmožno oddajati motno difuzno svetlobo po celotni navzven vidni površini leče 4, in pri čemer gre za svetlobo enakomerne jakosti brez ostrih kontrastnih prehodov in/ali bleščanja.vehicles of small dimensions, in particular with a relatively small dimension in the direction of the optical axis, i.e. the depth of the luminaire in the direction of the light exiting into the luminaire environment, the luminaire being capable of transmitting cloudy diffuse light over the entire outwardly visible surface of the lens 4, and providing light of uniform intensity without sharp contrast transitions and / or glare.
