Izum spada na področje transporta, konkretno k svetlobni opremi za vozila, namreč k svetilom za motorna vozila, še zlasti k prednjim žarometom ali žarometom za meglo.The invention relates to the field of transport, in particular to vehicle lighting equipment, namely to motor vehicle lamps, and in particular to front or fog lamps.
Pri tem je izum osnovan na problemu, kako pri svetilu motornega vozila navzlic razmeroma majhni prostornini iz termoplastičnega materiala sestoječega ohišja tudi v primeru uporabe razmeroma močnega vira svetlobe z visoko emisijo svetlobe in toplote v kombinaciji z omenjenim z ohišjem in reflektorjem iz termoplastičnega materiala na osnovi polimerov preprečiti pregrevanje reflektorja in/ali ohišja zaradi lokalnih termičnih obremenitev le-teh v bližini svetlobnega vira.The invention is based on the problem of how a relatively small volume of thermoplastic material of an enclosure is used in a motor vehicle luminaire, even when a relatively strong light source with high light and heat emission is used in combination with said polymer-based thermoplastic material and reflector. prevent overheating of the reflector and / or housing due to local thermal loads of these near the light source.
Svetilo za motoma vozila je opisano v US 3,486,019. Tovrstno svetilo obsega ohišje z za svetlobo prepustno prednjo steno oz. lečo, v ohišju pa je skupaj s svetlobnim virom vgrajen reflektor, ki je prirejen za preusmerjanje s svetlobnim virom generiranih svetlobnih žarkov skozi omenjeno prednjo steno in s tem v območje pred svetilom oz.The vehicle's motorcycle lamp is described in US 3,486,019. This type of light comprises a housing with a light-permeable front wall or a light-transmitting front. a lens and a reflector in the housing together with a light source which is adapted to be diverted by the light source of the light rays generated through said front wall and thus into the area in front of the light or light.
vozilom. Pri tem je omenjen svetlobni vir praktično obdan z reflektorjem. Reflektorje na svojem obodu povezan z omenjenim ohišjem, v osrednjem območju pa obsega prehod, skozi katerega je vstavljen oz. poteka svetlobni vir. V območju omenjenega prehoda je med svetlobnim virom in reflektorjem vgrajen toplotno prevoden element, takoimenovan ponor svetlobe, preko katerega se del toplote, ki jo skupaj s svetlobo generira svetlobni vir, odvaja iz ohišja v okolico. Tako je svetlobni vir vgrajen praktično v omenjenem toplotno prevodnem elementu in je skupaj s svetlobnim virom tudi sam praktično obdan z reflektorjem. Omenjeni dokument po eni strani izvira še iz časov, ko so ohišja in reflektorje izdelovali iz toplotno razmeroma dobro obstojnih kovinskih materialov, preprosta bikonveksna oz. lečasta oblika ohišja pa po drugi strani ne nakazuje na pretirane zahteve glede prostorninskih omejitev svetila kot takega.vehicle. The said light source is practically surrounded by a reflector. The reflectors at its perimeter are connected to the said housing, and in the central area comprises a passage through which it is inserted or. a light source is running. In the region of said passage, a thermally conductive element, a so-called light sink, is installed between the light source and the reflector, through which a portion of the heat generated by the light source together with the light is discharged from the housing to the surroundings. Thus, the light source is embedded practically in said thermally conductive element and together with the light source itself is practically surrounded by a reflector. This document, on the one hand, dates back to the time when housings and reflectors were made of relatively well-persistent metal materials, simple biconvex or. however, the lenticular shape of the case does not indicate excessive requirements regarding the volume limitations of the lamp as such.
Obravnavani izum se nanaša na svetilo motornega vozila, zlasti na prednji žaromet ali meglenko.

Pri alternativni izvedbi svetila po izumu omenjen cevast toplotno prevoden element vsaj deloma sega izven ohišja, in sicer še zlasti v območju zadnjega dela ohišja nasproti prednje stene, pri tem pa je med ohišjem in elementom nameščeno tesnilo za zagotavljanje tesnenja med njima.In one of the possible embodiments of the invention, said tubular thermally conductive element is completely located inside the housing. In an alternative embodiment of the lamp according to the invention, said tubular thermally conductive element extends at least partially outside the housing, particularly in the region of the rear of the housing opposite the front wall, with a gasket being provided between the housing and the element to provide a seal between them.
Nadalje je po izumu predvidena izvedba svetila, pri kateri je reflektor z omenjenim cevastim toplotno prevodnim elementom nerazstavljivo povezan, kot tudi alternativna izvedba, pri kateri je reflektor z omenjenim cevastim toplotno prevodnim elementom razstavljivo povezan, in sicer še zlasti na tak način, da je reflektor zaskočljiv v omenjen cevast toplotno prevoden element.Furthermore, according to the invention, there is provided a lamp in which the reflector is connected to said tubular thermally conductive element, as well as an alternative embodiment in which the reflector is connected to said tubular thermally conductive element, in particular in such a way that the reflector is snap into said tubular thermally conductive element.

Na Sl. 1 - 3 je shematično ponazorjeno svetilo motornega vozila v funkciji meglenke, kije po izbiri kombinirana s kotno svetilko, smernim kazalcem ali podobnim.In FIG. 1 - 3 is a schematically illustrated motor vehicle lamp in the function of a fog lamp, which is optionally combined with an angle lamp, a direction indicator or the like.
Svetilo obsega ohišje 1 iz termoplastičnega polimernega materiala, ki je lahko in ga je možno izdelati na ekonomičen način. Ohišje 1 je opremljeno z za svetlobo prepustno optično aktivno ali pasivno prednjo steno 10, kar za strokovnjaka na razumljiv način pomeni, da omenjena stena 10 po izbiri lahko tudi v funkciji leče. Ohišje 1 je nadalje prirejeno za vgradnjo vsaj enega svetlobnega vira 2 v njegovo notranjost, namreč halogenske žarnice z vsaj eno žarilno nitko 20, npr. tipska žarnice H4.The luminaire comprises a housing 1 made of thermoplastic polymeric material which can be and can be produced economically. The housing 1 is provided with a light-transmitting optically active or passive front wall 10, which for a person skilled in the art means that said wall 10 may optionally also function as a lens. The housing 1 is further adapted to incorporate at least one light source 2 into its interior, namely halogen lamps with at least one filament 20, e.g. type bulb H4.
Razen tega je v notranjosti omenjenega ohišja 1 vgrajen reflektor 3, ki tako kot ohišje 1 sestoji iz termoplastičnega polimernega materiala in s katerim je vsaj pretežno obdan omenjen svetlobni vir 2. Reflektor 3 obsega vsaj eno proti omenjenemu svetlobnemu viru 2 obrnjeno refleksijsko površino 30, na kateri se z žarilno nitko 20 svetlobnega vira 2 generirani svetlobni žarki preusmerijo proti omenjeni za svetlobo prepustni prednji steni 10 ohišja 1 in potem skoznjo v območje pred svetilom oz. vsakokratnim vozilom.In addition, a reflector 3 is mounted inside said housing 1, which, like housing 1, consists of a thermoplastic polymeric material and with which at least predominantly surrounds said light source 2. The reflector 3 comprises at least one reflecting surface 30 towards said light source 2, at which, through the filament 20 of the light source 2, the generated light beams are directed to the light-transmitting front wall 10 of the housing 1, and then pass to the area in front of the light or light. to each vehicle.
Položaj reflektorja 3 glede na ohišje 1 po izbiri nastavljiv s pomočjo primernega regulacijskega sklopa 4, ki sestoji npr. iz členkaste povezave npr. krogelnega zgloba med ohišjem 1 in reflektorjem 3 in primernega regulacijskega vijaka, ki je vrtljivo uležajen na ohišju in sodeluje z matico, ki je povezana z reflektorjem. RegulacijskiThe position of the reflector 3 with respect to the housing 1 is optionally adjustable by means of a suitable control unit 4 consisting e.g. from an articulated link e.g. the ball joint between the housing 1 and the reflector 3 and a suitable control screw which is pivotally mounted on the housing and cooperates with a nut connected to the reflector. Regulatory
sklop 4 je strokovnjakom s tega področja nedvomno znan v različnih izvedbah in kot tak ni predmet izuma, zaradi česar na skici niti ni podrobneje prikazan.Lot 4 is clearly known to those skilled in the art in various embodiments and as such is not the subject of the invention, which is why it is not even shown in more detail.
Po izumu je v notranjosti omenjenega ohišja 1 predviden v svoji obodni smeri sklenjen cevast toplotno prevoden element 5, v notranjosti katerega sta vstavljena vsaj pretežno z reflektorjem 3 iz termoplastičnega polimernega materiala obdan svetlobni vir 2 z žarilno nitko 20 in reflektor 3, tako da je omenjeni reflektor 3 v celoti obdan z omenjenim elementom 5 in s slednjim togo povezan.According to the invention, a tubular thermally conductive element 5 is provided in the circumferential direction of said housing 1 in the interior of which a light source 2 with filament 20 and a reflector 3 are inserted at least substantially with a reflector 3 of thermoplastic polymeric material. the reflector 3 is completely surrounded by said element 5 and rigidly connected therewith.
Pri tem je svetlobni vir 2 povsem neodvisno od reflektorja 3 po izbiri vgrajen bodisi v omenjen cevast toplotno prevoden element 5 ali pa neposredno v ohišje 1 svetila.In this case, the light source 2 is optionally mounted independently of the reflector 3 either in said tubular thermally conductive element 5 or directly in the lamp housing 1.
Regulacijski sklop 4 je prirejen za uravnavanje položaja omenjenega cevastega toplotno prevodnega elementa 5 skupaj z v njem vgrajenim in z njim togo povezanim reflektorjem 3 glede na vsakokrat razpoložljivo ohišje 1 svetila. Upoštevajoč znane in razpoložljive regulacijske sklope 4 gre v tem primeru za enak ali popolnoma podoben sklop 4, preko katerega je namesto povezave med ohišjem 1 in reflektorjem 3 kot v številnih doslej znanih izvedbah svetil v tem primeru po izumu vzpostavljena povezava in korelacija med ohišjem 1 in omenjenim cevastim toplotno prevodnim elementom 5.The control unit 4 is adapted to adjust the position of said tubular thermally conductive element 5 together with the reflector 3 integrated therein and the rigidly coupled reflector 3 thereof with respect to the lamp housing 1 available at each time. Considering the known and available control circuits 4, in this case, it is the same or completely similar circuit 4 through which, instead of the connection between the housing 1 and the reflector 3, as in many known versions of the lamps in the present case, the connection and correlation between the housing 1 and said tubular thermal conductive element 5.
Pri eni od možnih izvedb svetila po izumu, ki je shematično ponazorjena na Sl. 1, se omenjen cevast toplotno prevoden element 5 v celoti nahaja v notranjosti ohišja 1.In one of the possible embodiments of the lamp according to the invention, which is schematically illustrated in FIG. 1, said tubular thermally conductive element 5 is completely located inside the housing 1.
Pri nadaljnji različici svetila po izumu (Sl. 2) pa omenjen cevast toplotno prevoden element 5 vsaj deloma sega izven ohišja 1, in sicer še zlasti v območju zadnjega dela ohišja 1 nasproti prednje stene 10. V takem primeru je med ohišjem 1 in cevastim toplotno prevodnim elementom 5 nameščeno tesnilo 6 za zagotavljanje tesnenja med njima, s čimer je preprečeno, da bi v notranjost ohišje 1 vdirala vlaga ali nečistoče od zunaj.In a further embodiment of the light according to the invention (Fig. 2), said tubular thermally conductive element 5 extends at least partially outside the housing 1, and especially in the region of the rear housing 1 opposite the front wall 10. In such a case, between the housing 1 and the tubular heat conductive element 5 is fitted with a seal 6 to provide a seal between them, preventing moisture or impurities from entering the housing 1 from the inside.
Omenjen cevast toplotno prevodni element 5 sestoji iz materiala, katerega prevodnost bistveno presega razmeroma slabo toplotno prevodnost termoplastičnega polimernega materiala, iz kakršnega sestoji ohišje 1 ali reflektor 3. Še zlasti je prednostno, če cevast toplotno prevodni element 5 sestoji iz aluminija, še zlasti npr. iz tlačno litega aluminija, ali iz magnezija, ali pa tudi iz primerne kovinske zlitine, ki se odlikuje po majhni specifični gostoti, dobri toplotni prevodnosti in temperaturni obstojnosti, npr. vsaj do temperature približno 200°C.Said tubular thermal conductive element 5 consists of a material whose conductivity substantially exceeds the relatively poor thermal conductivity of the thermoplastic polymeric material, such as housing 1 or reflector 3. It is particularly preferred if the tubular thermal conductive element 5 consists of aluminum, in particular e.g. die-cast aluminum or magnesium or a suitable metal alloy with low specific density, good thermal conductivity and temperature resistance, e.g. at least to a temperature of about 200 ° C.
Temu ustrezno je potem reflektor 3 iz termoplastičnega polimernega materiala z omenjenim cevastim toplotno prevodnim elementom 5 lahko nerazstavljivo povezan, kar se v praksi lahko doseže z brizganjem reflektorja 3 v ustreznem orodju neposredno na/v element 5. Po drugi strani je po izumu brez nadaljnjega možna tudi izvedba svetila, pri kateri je reflektor 3 z omenjenim cevastim toplotno prevodnim elementom 5 razstavljivo povezan in je v takem primeru še najbolj prednostno po zaključeni površinski obdelavi elementa 5, npr. lakiranju, preprosto zaskočljiv in/ali privijačen v omenjen cevast toplotno prevoden element 5.Accordingly, the reflector 3 of thermoplastic polymer material with said tubular thermal conductive element 5 can then be indistinguishably connected, which in practice can be achieved by spraying the reflector 3 in the corresponding tool directly onto / into the element 5. On the other hand, it is possible without further invention also a luminaire arrangement in which the reflector 3 is detachably connected to said tubular thermally conductive element 5 and in this case is most preferably after the surface treatment of the element 5 is completed, e.g. lacquer, simply snap-in and / or screwed into said tubular thermally conductive element 5.
Nadalje je po izbiri reflektor 3 glede na vsakokraten položaj uporabe svetila, vsaj v območju vertikalno nad žarilno nitko 20 svetlobnega vira 2 opremljen z izrezom 31, v območju katerega je na voljo neposreden prehod med svetlobnim virom 2 in toplotno prevodnim elementom 5 mimo samega reflektorja 3. Kadar sta svetlobni vir 2 in reflektor 3 tako zasnovana, da glede na položaj svetila med uporabo reflektor 3 poteka nad svetlobnim virom 2 oz. preko slednjega, se je s takim ukrepom mogoče elegantno izogniti pregrevanju materiala reflektorja 3 v območju neposredno nad svetlobnim virom 2, ne da bi bila velikost njegove refleksijske površine 30 bistveno okrnjena.Further, the reflector 3 is optionally provided with a notch 31, at least in the area vertically above the filament 20 of the light source 2, in the area of which a direct passage between the light source 2 and the thermally conductive element 5 is passed past the reflector 3 itself. When the light source 2 and the reflector 3 are so designed that, depending on the position of the lamp, the reflector 3 extends above the light source 2 or. through the latter, such a measure can elegantly avoid overheating of the reflector material 3 in the area directly above the light source 2 without significantly reducing the size of its reflecting surface 30.
Nadalje je po izumu predvideno, da je notranja površina 50 glede na vsakokraten položaj svetila med uporabo vsaj tistem v območju 51 cevastega toplotno prevodnega elementa 5, ki se nahaja vertikalno pod svetlobnim virom 2, z zatemnitvijo oz. počmitvijo prirejena za izboljšanje absorpcije toplote, oziroma po izbiri, daje notranjaFurthermore, according to the invention, it is provided that the inner surface 50, depending on the respective position of the lamp, is in use at least that in the area 51 of the tubular thermally conductive element 5, which is vertically below the light source 2 by dimming or. a recess designed to improve heat absorption, or optionally, provides an interior
površina 50 cevastega toplotno prevodnega elementa 5 v celoti zatemnjena oz. črna in s tem prirejena za izboljšanje absorpcije toplote in doseganje tudi nekaterih drugih učinkov, med drugim tudi disipacije svetlobnih žarkov v smislu zmanjšanja bleščanja.the surface 50 of the tubular thermally conductive element 5 is completely obscured. black and thus adapted to improve heat absorption and to achieve some other effects, including the dissipation of light rays in terms of reducing glare.
S tovrstnim ukrepom se še zlasti doseže, da je na voljo dovolj velika površina, ki absorbira znaten del toplote, ki se sprošča v svetlobnem viru 2. Glavnina toplotnih tokov je sicer usmerjena od svetlobnega vira 2 navzgor proti reflektorju 3 in ohišju 1, vendar pa to toploto v danem primeru prestreže cevast toplotno prevoden element 5, ki je tudi po svojem obodu sklenjen. Zahvaljujoč toplotni prevodnosti omenjenega cevastega elementa 5 in obenem zahvaljujoč dejstvu, da se v elementu 5 vseskozi skuša vzpostaviti toplotno ravnovesje, se v materialu samega elementa 5 vzpostavi toplotni tok, ki prenaša toploto iz toplejših v hladnejša območja. S tem se toplota iz toplotno najbolj obremenjenega območja nad svetlobnim virom 2 vseskozi sproti in intenzivno prevaja na ostale lokacije po celotnem obodu elementa 5, od koder se postopoma prenaša na sosednja območja ohišja 1 in tako navzlic slabi toplotni prevodnosti termoplastičnega polimernega materiala ohišja 1 zahvaljujoč razmeroma veliki površini ohišja 1 postopoma ven iz le-tega.This measure, in particular, achieves a sufficiently large surface area to absorb a significant portion of the heat released in the light source 2. Although most of the heat fluxes are directed from the light source 2 upwards to the reflector 3 and the housing 1, however, this heat is, in the case at hand, intercepted by a tubular thermally conductive element 5 which is also contracted at its circumference. Due to the thermal conductivity of said tubular element 5, and at the same time due to the fact that the element 5 is constantly trying to achieve thermal equilibrium, a heat flow is generated in the material of the element 5 itself, which transfers heat from warmer to colder regions. In this way, the heat from the heat-stressed area above the light source 2 is constantly and intensively transferred to other locations throughout the circumference of the element 5, from which it is gradually transferred to the adjacent areas of the housing 1, thus, due to the poor thermal conductivity of the thermoplastic polymer material of the housing 1 thanks to a relatively the large surface of the housing 1 is gradually out of it.
Poleg prej naštetih izvedb svetila izuma je nadalje v splošnem predvidena tudi izvedba, pri kateri je vsaj notranja površina 50 toplotno prevodnega elementa 5 vsaj deloma reflektivna ali drugače prirejena za zagotavljanje želenega estetskega videza.In addition to the aforementioned embodiments of the luminaire of the invention, there is also generally provided an embodiment in which at least the inner surface 50 of the thermally conductive element 5 is at least partially reflective or otherwise adapted to provide the desired aesthetic appearance.
