Abstract

The illumnant consists of a light module (1) and a complementary module (2). The light module (1) features an enclosure (11) for receiving the reflector (12), which is on the front side closed with a light non- permeable wall (13), while the complementary module (2) includes at least a selected light source (251, 252, 254, 254) with the corresponding supply and control elements (23, 25) and corresponding enclosure (20) which is on the rear side closed by a cover (24) and includes a front wall (200) made from heat conductive material looking towards the light module (1) and at least one passage (202) located directly next to the aforementioned wall (200) standing in at least approximately vertical direction. Such a concept on one side but also with a relatively small illumnant ensures the possibility that instead of the currently used standard bulbs LED diodes (251, 252, 253, 254) can be used as the light source. From the aspect of installation into any vehicle the relevant external dimensions of the illuminant regardless of the selected light source (251, 252, 253, 254) remain practically unchanged. At the same time the key components of the illuminant despite the specified alternative option of selecting the light source (251, 252, 253, 254) remain completely unchanged.

Description

Svetilo, zlasti za motorna vozilaLighting, especially for motor vehicles

Izum v splošnem spada na področje osvetljevanja, kjer zadeva predvsem hlajenje svetil. V kontekstu prednostne aplikacije izuma je slednjega na področju transporta možno uvrstiti na področje svetil za osvetljevanje vozišča pred vozilom, zlasti žarometov, dodatnih npr. dnevnih luči, meglenk ali podobne svetlobne oz. signalne opreme za vozila.The invention generally falls within the field of lighting, in which light is primarily concerned with cooling. In the context of the preferred application of the invention, the latter in the field of transport can be classified in the field of lighting for the carriageway in front of the vehicle, in particular headlamps, e.g. daytime running lights, fog lights or similar light or signaling equipment for vehicles.

Pri tem je izum osnovan na problemu, kako pri razmeroma majhnem svetilu v zaprti izvedbi, pri katerem je vsakokraten izvor svetlobe nameščen v območju reflektorja, ki je obdan z ohišjem, ki je na prednji strani zaprto in proti vremenskim vplivom zaščiteno z za svetlobo prepustno steno ali lečo, na zadnji strani pa z ustrezno tesnjenim pokrovom, zagotoviti možnost, da bi bile kot izvor svetlobe namesto doslej uporabljanih žarnic z žarilno nitko, zlasti halogenskih, po izbiri lahko uporabljene diode, pri čemer naj bi v pogledu vgradnje v vsakokratno vozilo zunanje izmere svetila ostale praktično nespremenjene, obenem pa naj bi vsaj nekateri ključni sestavni deli svetila ostali navzlic omenjeni alternativni možnosti izbire izvora svetlobe ostali popolnoma nespremenjeni.The invention is based on the problem of how, in a relatively small, closed-type luminaire, each light source is located in a reflector area surrounded by a housing which is closed at the front and protected from the weather by a light-permeable wall or lens and, on the back, with a properly sealed lid, the possibility of optionally using diodes as the light source instead of the filament lamps used, especially halogen lamps, which may optionally be external, with external dimensions in view of installation in the vehicle in question. the lamps remain virtually unchanged, while at least some of the key components of the lamp remain out of line with the aforementioned alternative of selecting a light source.

V stanju tehnike so opisani številni žarometi, pri katerih je kot izvor svetlobe predvidena zlasti halogenska žarnica z žarilno nitko, ki je vstavljena v ustreznem okovu in obdana z reflektorjem za formiranje želenega svetlobnega snopa in usmerjanje generirane svetlobe v vsakokrat želeno smer. Omenjeni reflektorje obdan z okrovom, ki pri sodobnih svetilih običajno sestoji iz polimernega gradiva in je na prednjem koncu na ustrezen način tesnjeno zaprt in proti vremenskim vplivom zaščiten z za svetlobo prepustno steno iz mineralnega ali termoplastičnega gradiva, na zadnjem koncu pa s pokrovom, ki običajno sestoji iz termoplastičnega gradiva. V notranjosti okrova so poleg omenjenega reflektorja lahko predvideni še drugi deli kot npr. različne zaslonke ali sredstva za regulacijo položaja reflektorja glede na vzdolžno os svetila in s tem regulacijo smeri svetlobnega snopa oz. pramena.In the prior art, many headlamps are described, in which a halogen filament lamp, which is inserted in a suitable fitting and surrounded by a reflector, is provided as the light source, to form the desired light beam and to direct the light generated in the desired direction. These reflectors are surrounded by a housing which, in modern lighting, typically consists of a polymeric material and is appropriately sealed at the front end and protected from the weather by a light-permeable wall of mineral or thermoplastic material, and at the rear end by a cover which is normally consists of thermoplastic material. In addition to said reflector, other parts, such as e.g. various apertures or means for adjusting the position of the reflector with respect to the longitudinal axis of the lamp and thereby regulating the direction of the light beam or the beam. strands.

Če je po eni strani zaželeno, da je svetilo zaprto, s čimer so v notranjosti okrova razpoložljivi sestavni deli zavarovani proti vremenskim vplivom, je tovrstna izvedba svetila izjemno problematična z vidika odvoda ustvarjene toplote iz notranjosti svetila v okolico. Žarnica z žarilno nitko namreč dovedeno energijo povečini pretvori v toploto, medtem ko vsa ustvarjena svetloba predstavlja zgolj majhen delež, približno 5% te energije. Uporaba svetil, pri katerih je kot svetlobni vir uporabljena žarnica z žarilno nitko, je vezana tudi na nekatere druge zahteve, ki izhajajo iz razmeroma kratke življenjske dobe žarnic oz. potrebe po njihovi občasni zamenjavi. Na tej osnovi se pri sodobnih svetilih pogosto kaže težnja po drugačni izbiri izvora svetlobe, še zlasti po nadomestitvi klasične žarnice z diodami. Pri uporabi diod kot izvora svetlobe je namreč mogoče računati tudi z znatno ugodnejšo toplotno bilanco, saj svetlobna energija predstavlja približno 20% dovedene energije. Navzlic temu tudi pri svetilih z diodami kot svetlobnim virom ustvarjena toplota predstavlja enega ključnih problemov, in sicer še zlasti kadar je izvor toplote zaprt v razmeroma majhnem prostoru, kar pri svetilih motornih vozil omenjene vrste vsekakor drži. To je še zlasti problematično, ker povečanje temperature v okolici diode med drugim v znatni meri vpliva na svetilnost diode, tako da pregrevanje ne vodi zgolj do možnosti poškodb drugih sestavnih delov v okolici diode, marveč tudi do neučinkovitosti svetila.If, on the one hand, it is desirable for the lamp to be closed, thereby securing the available components against the effects of the interior, this type of luminaire design is extremely problematic in terms of the heat generated from the interior of the luminaire into the surroundings. The incandescent bulb, for the most part, converts the energy that it supplies into heat, while all the light generated represents only a small fraction, about 5% of that energy. The use of lamps which use a filament lamp as a light source is also related to some other requirements arising from the relatively short life of the lamps. the need for their occasional replacement. On this basis, modern luminaries often show a tendency to choose a different light source, especially after replacing a classic light bulb with diodes. When using diodes as a light source, it is also possible to calculate a significantly more favorable heat balance, since light energy represents about 20% of the energy input. However, even with LEDs as a light source, the heat generated is one of the key problems, especially when the heat source is closed in a relatively small space, which certainly holds true for motor vehicle lights. This is especially problematic because increasing the temperature around the diode, among other things, significantly affects the luminosity of the diode, so overheating does not only lead to the possibility of damage to other components in the diode environment, but also to the inefficiency of the luminaire.

Strokovnjakom so nedvomno znane številne rešitve sodobnih svetil, pri katerih je klasična žarnica nadomeščena z diodami. Uporaba diod namreč narekuje prisotnost ustreznega elektronskega vezja, neredko tudi transformatorja ali podobnih električnih ali elektronskih sklopov, ki tudi lahko generirajo toploto. Vse te komponente praviloma narekujejo globalno spremembo koncepta izvedbe svetila vključno z vgradnimi dimenzijami, kar je povezano s prilagajanjem ostalih sestavnih delov vozila novi zasnovi svetila in konec koncev tudi prilagajanje tehnologije same izdelave tako zasnovanega svetila. Zlasti to slednje je povezano z ogromnimi vlaganji v nova orodja in naprave, medtem ko z vidika proizvajalca to pomeni predvsem velike omejitve glede možnosti izbire med vgradnjo bodisi svetil s klasičnimi svetlobnim virom ali svetil z diodami pri določenem tipu vozila. Oboje je vsekakor neugodno tako za proizvajalca svetlobne opreme kot tudi za proizvajalca vozila oz. njegove potencialne kupce.Many of the solutions of modern lamps are known to those skilled in the art, in which the classical light bulb is replaced by diodes. The use of diodes dictates the presence of a suitable electronic circuit, often a transformer or similar electrical or electronic circuits, which can also generate heat. As a rule, all these components dictate a global change in the concept of the luminaire's design, including its mounting dimensions, which is related to the adaptation of other vehicle components to the new luminaire design and, ultimately, the adaptation of the technology of the lamp itself. In particular, the latter is associated with huge investments in new tools and appliances, while from the manufacturer's point of view, this implies, in particular, large restrictions on the choice between fitting either conventional light sources or LEDs to a specific vehicle type. Both are definitely disadvantageous for both the lighting manufacturer and the vehicle manufacturer. its potential customers.

Kot primer tovrstne preureditve je možno navesti zavorno luč po DE 20 2004 016 669 Ul, pri kateri svetilo obsega niz hladilnih reber iz toplotno prevodnega gradiva, zaradi česar so popolnoma spremenjene vgradne izmere, pa tudi izgled svetila je popolnoma spremenjen.As an example of this kind of rearrangement, a brake light according to DE 20 2004 016 669 Ul can be given, in which the luminaire comprises a series of cooling fins made of thermally conductive material, which makes the recessed dimensions completely changed, as well as the appearance of the luminaire completely changed.

Po drugi strani pa DE 20 2006 009 553 Ul predlaga svetilo z diodo kot izvorom svetlobe, pri čemer gre za običajno svetilo, ki med drugim obsega tudi transformator. Ne glede na to je predlagano, da je vezje s pripadajočo diodo obdano s hladilnim sklopom, ki sestoji iz med seboj enakomerno razmaknjenih radialno navzven štrlečih reber, ki formirajo v obliki prisekanega stožca izveden hladilnik, pri čemer je dolžina omenjenih reber hladilnika na strani diode večja kot na preostalem koncu hladilnika. Če bi tovrstno rešitev uporabili pri svetilu za vozila, bi se kot posledica popolnoma spremenjene zasnove svetila tudi vgradne mere svetila nedvomno že v osnovi nedvomno bistveno spremenile.DE 20 2006 009 553 Ul, on the other hand, proposes a light emitting diode as a light source, which is a conventional light comprising, among other things, a transformer. Nonetheless, it is proposed that the circuit of the associated diode is surrounded by a cooling assembly consisting of radially outwardly projecting ribs, spaced apart from each other, forming a truncated cone, the length of said radiator ribs on the diode side being greater as on the rest of the refrigerator. If such a solution were used in vehicle lighting, as a consequence of a completely changed design of the luminaire, the recessed dimensions of the luminaire would undoubtedly have undergone significant changes.

Še nadalje je v W0 2007/042552 Al oz. DE 10 2005 049 685.7 predlagan večnamenski modul žarometa za motorna vozila, pri katerem je dioda nameščena na elektronskem vezju, ki je vgrajeno v približno cilindričnem oz. cevastem ponoru toplote iz toplotno prevodnega gradiva, ki je z namenom povečanja za prenos toplote na okolico razpoložljive površine po obodu opremljen z nizom reber in utorov. Tak ponor toplote je sicer lahko nameščen tudi v okrovu iz termoplastičnega gradiva, vendar bi v tem primeru toplota z diode sicer prehajala na ponor toplote, medtem ko bi odvod toplote z omenjenega ponora toplote ven iz ohišja ostal v celoti nerešen.Furthermore, in W0 2007/042552 Al or. DE 10 2005 049 685.7 a proposed multi-purpose headlamp module for motor vehicles in which the diode is mounted on an electronic circuit which is mounted in an approximately cylindrical or a tubular heat sink made of thermally conductive material, which is equipped with a series of ribs and grooves to increase the heat transfer to the surrounding surface of the available surface around the perimeter. Such a heat sink may also be housed in a thermoplastic material enclosure, but in this case, the heat from the diode would otherwise pass to the heat sink, while leaving the heat sink from said heat sink out of the housing would remain completely unresolved.

Izum se nanaša na svetilo, zlasti za motoma vozila, ki obsega vsaj en v območju reflektorja razporejen svetlobni vir, ki je tako kot vsakokraten reflektor obdan z okrovom, ki je - gledano v smeri ustvarjenega svetlobnega pramena - na prednji strani tesnjeno zaprt in s tem proti vremenskim in mehanskim zunanjim vplivom zaščiten z za svetlobo prepustno ter optično bodisi aktivno ali pasivno steno, na zadnji strani pa s primernim pokrovom.The invention relates to a lamp, in particular for the moto of a vehicle, comprising at least one light source arranged in the area of the reflector, which, like the respective reflector, is enclosed by a housing which, when viewed in the direction of the generated beam, is sealed in the front and thereby against weather and mechanical external influences protected by a light-transmitting and optically either active or passive wall and at the rear by a suitable cover.

Po izumu je predlagano, da tovrstno svetilo v osnovi sestoji iz svetlobnega modula in komplementarnega modula, kije - gledano v smeri vsakokrat ustvarjenega svetlobnega pramena - z zadnje strani vsaj približno soosno priključen k omenjenemu svetlobnemu modulu, pri čemer omenjeni svetlobni modul obsega svetlobni vir obdajajoč okrov, ki je na prednji strani zaprt z za svetlobo prepustno steno, medtem ko komplementarni modul pa obsega vsaj vsakokrat izbran in z reflektorjem obdan svetlobni vir s pripadajočimi napajalnimi in krmilnimi komponentami in pripadajočim okrovom, kije na zadnji strani zaprt s pokrovom in obsega vsaj proti svetlobnemu modulu obrnjeno prednjo steno iz toplotno prevodnega gradiva ter vsaj en neposredno ob omenjeni steni razporejen in vsaj približno v vertikalni smeri potekajoč skoznji prehod.According to the invention, it is proposed that such a light consists essentially of a light module and a complementary module, which - viewed in the direction of the light beam generated at the rear - is at least approximately coaxially connected to said light module, said light module comprising a light source surrounding the enclosure , which is enclosed at the front by a light-permeable wall, while the complementary module comprises at least each selected and reflected reflector a light source with associated power and control components and associated housing, which at the rear is closed by a cover and extends at least toward the illumination Module facing the front wall of thermally conductive material and at least one directly adjacent to said wall and passing through it at least in a vertical direction.

Pri prednostni izvedbi svetila po izumu komplementarni modul obsega okrov, ki v celoti sestoji iz toplotno prevodnega gradiva. V tem primeru je komplementarni modul neposredno ob prednji, proti svetlobnemu modulu obrnjeni toplotno prevodni steni opremljen z vsaj dvema vsaj približno v vertikalni smeri potekajočima skoznjima prehodoma, pri čemer je med vsakokrat sosednjima prehodoma na voljo vsakokrat po eno toplotno prevodno rebro. Se zlasti je prednostno, če je komplementarni modul neposredno ob prednji, proti svetlobnemu modulu obrnjeni toplotno prevodni steni opremljen z nizom vsaj približno v vertikalni smeri potekajočih skoznjih prehodov, pri čemer sta vsakokrat sosednja prehoda med seboj ločena s toplotno prevodnim rebrom.In a preferred embodiment of the luminaire according to the invention, the complementary module comprises a housing which consists entirely of thermally conductive material. In this case, the complementary module immediately adjacent to the front, towards the light module facing heat conduction wall, is provided with at least two at least vertically passing through passages, with one heat conductive rib being available at each time between adjacent passages. In particular, it is advantageous if the complementary module directly adjacent to the light module facing the light module is provided with a series of at least approximately vertical crossings passing through, each time the adjacent passages are separated by a heat conducting rib.

Komplementarni modul prednostne izvedbe svetila po izumu obsega elektronsko vezje z diodami, ki štrlijo v območje reflektorja svetlobnega modula. Omenjeno vezje je razporejeno na proti svetlobnemu modulu obrnjeni strani okrova komplementarnega modula, onstran omenjenih prehodov in torej na proti pokrovu obrnjeni strani okrova komplementarnega modula pa je razporejena ustrezna elektronska krmilna enota, preko katere je nameščen pokrov, ki sestoji iz električno prevodnega gradiva, prednostno iz električno in toplotno prevodnega gradiva in še zlasti iz kovinskega gradiva.The complementary module of the preferred embodiment of the light according to the invention comprises an electronic circuit with diodes projecting into the reflector area of the light module. Said circuit is arranged on the side of the complementary module housing facing the light module, and beyond the aforementioned passages, and therefore on the housing side of the complementary module facing side, a corresponding electronic control unit is arranged over which a cover consisting of electrically conductive material, preferably from electrically and thermally conductive materials, and in particular of metallic materials.

Med pokrovom in okrovom komplementarnega modula je prednostno predvideno tesnilo, prav tako je prednostno kot O-obroč zasnovano tesnilo prednostno predvideno med okrovom komplementarnega modula in okrovom svetlobnega modula.A seal is provided between the lid and the complementary module housing, as well as the O-ring-based seal is preferably provided between the complementary module housing and the light module housing.

Svetlobni modul svetila po izumu je načeloma prirejen za sodelovanje bodisi s komplementarnim modulom z vgrajeno vsaj eno diodo kot svetlobnim virom, ali tudi s S klasično zasnovanim komplementarnim modulom, v katerem je vgrajen vsaj ena v območje reflektorja v svetlobnem modulu segajoča žarnica z žarilno nitko, kakršna v takem primeru predstavlja svetlobni vir svetila po izumu.The light module of the invention according to the invention is, in principle, adapted to cooperate either with a complementary module with at least one diode as a light source or with a classically designed complementary module incorporating at least one filament lamp extending into the area of the reflector, which in such a case represents the light source of the light according to the invention.

Izum bo v nadaljevanju obrazložen na osnovi primera izvedbe, ki je prikazan na priloženi skici, kjerThe invention will hereinafter be explained on the basis of the embodiment shown in the accompanying drawing, where

Sl. 1 kaže shematično ponazorjeno svetilo po izumu v prerezu v vertikalni ravnini,FIG. 1 shows a schematically illustrated cross-sectional light according to the invention in a vertical plane,

Sl. 2 pa svetilo po Sl 1 v eksplozijskem prikazu.FIG. 2 is a lamp according to FIG. 1 in the exploded view.

Svetilo po izumu načeloma sestoji iz svetlobnega modula 1, ki je v pogledu dimenzij in tehnoloških pogojev izdelave invarianten glede na vsakokrat uporabljen svetlobni vir, kot tudi iz vsakokrat pripadajočega komplementarnega modula 2. Omenjena invariantnost svetlobnega modula 1 glede na vsakokrat uporabljen svetlobni vir pomeni, daje svetlobni modul 1 tako v pogledu vgradnih dimenzij kot tudi v pogledu tehnoloških pogojev izdelave lahko enak v primeru uporabe bodisi klasične žarnice z žarilno nitko ali diod kot svetlobnega vira.The luminaire according to the invention consists in principle of a light module 1 which, in terms of dimensions and technological conditions of manufacture, is invariant to the light source used in each case, as well as to the corresponding complementary module 2. Said invariance of the light module 1 to the light source used in each case means that the light module 1, both in terms of installation dimensions and in terms of technological conditions of manufacture, may be the same when using either a conventional filament lamp or a diode as a light source.

Svetlobni modul 1 sestoji iz okrova 11, ki je prirejen za prejem reflektorja 12 in spredaj tesno zaprt z za svetlobo prepustno steno 13, ki je lahko optično pasivna ali optično aktivna in deluje npr. kot zbiralna ali razpršilna leča ali pa npr. svetlobo obarva..The light module 1 consists of a housing 11 which is adapted to receive a reflector 12 and is closed tightly in front with a light-permeable wall 13, which may be optically passive or optically active and function e.g. as a collection or spray lens or e.g. the color is colored ..

K omenjenemu svetlobnemu modulu 1 je z zadnje strani v bistvu soosno in s pomočjo tesnila 27 tesnjeno prigrajen komplementarni modul 2, ki obsega okrov 20, katerega proti svetlobnemu modulu 1 obrnjena stena 200 sestoji iz primernega toplotno prevodnega gradiva, lahko npr. celo iz termoplastične umetne mase z izrazito ugodno toplotno prevodnostjo, omenjeni okrov 20 pa je razen tega opremljen z nizom med seboj z ustreznimi rebri 201 ločenih in vsaj približno v vertikalni smeri potekajočih skoznjih prehodov 202. Na pročelni strani 21 okrova 20 modula 2 je razporejeno elektronsko vezje 25 z diodami 251, 252, 253, 254, ki segajo v območje reflektorja 12, medtem ko je na hrbtni strani 22 okrova 20 omenjenega modula 2 na voljo omenjenemu vezju 25 in diodam 251, 252, 253, 254 pripadajoča krmilna enota 23, preko katere je na okrov 20 prednostno preko primernega tesnila 26 pritrjen pokrov 24. Ker je omenjeni pokrov 24 prednostno izveden iz kovinskega gradiva, po eni strani zagotavlja zaščito omenjenih elektronskih komponent 23, 25, 251, 252, 253, 254 komplementarnega modula 2 proti zunanjim vremenskim in mehanskim vplivom, obenem pa formira strokovnjakom znano Farradayevo kletko in s tem varuje krmilno enoto 23 proti električnim in drugim motnjam, ki bi jih v nasprotnem primeru lahko povzročale druge v vozilu vgrajene električne in elektronske komponente.To said light module 1, a complementary module 2 comprising a housing 20 substantially coaxially and substantially coaxially attached to the rear side by means of a gasket 27, whose wall facing 200 consists of suitable thermally conductive material, e.g. even of thermoplastic plastic with extremely favorable thermal conductivity, said housing 20 being further provided with a series of interconnected ribs 201 separated at least vertically by passing through transitions 202. On the front side 21 of module 20 housing 20 is arranged electronically a circuit 25 with diodes 251, 252, 253, 254 extending into the area of the reflector 12, while at the back 22 of the housing 20 of said module 2 is available to said circuit 25 and diodes 251, 252, 253, 254 the associated control unit 23, through which a cover 24 is preferably attached to the housing 20 via a suitable seal 26. Since said cover 24 is preferably made of metal material, on the one hand, it provides protection for said electronic components 23, 25, 251, 252, 253, 254 of the complementary module 2 against external weathering and mechanical influences, while forming a well-known Farraday cage for the experts, thereby protecting the control unit 23 against electrical and other interference that would otherwise, they may be caused by other electrical and electronic components installed in the vehicle.

Zahvaljujoč tovrstni zasnovi svetila po izumu je torej predviden svetlobni modul 1, katerega vgradne mere ustrezajo obstoječim vgradnim meram pri ekvivalentnem svetilu, pri katerem je kot svetlobni vir uporabljena žarnica z žarilno nitko. Ne glede na možnost izbire v pogledu vgradnje bodisi klasične žarnice ali diod 251, 252, 253, 254 kot svetlobnega vira ostaja omenjeni modul 1 tako v pogledu vgradnih dimenzij, oblike in tehnologije izdelave popolnoma nespremenljiv. Po drugi strani je komplementarni modul 2 na voljo bodisi v izvedbi z diodami 251, 252, 253, 254 (Sl. 1 ali 2) ali v klasični izvedbi, kjer je v ustreznem okrovu vgrajen okov žarnice, okrov pa je z zadnje strani zaprt s pokrovom, pri čemer je tudi komplementarni modul 2 potem v obeh izvedbah dimenzijsko lahko povsem enak, kar seveda pomeni, da so ob enakih zunanjih merah obeh modulov 1, 2 potemtakem ne glede na izbiro svetlobnega vira vgradne dimenzije vseskozi enake oz. nespremenljive.Thanks to this design of the luminaire according to the invention, a light module 1 is thus provided, whose mounting dimensions correspond to the existing mounting dimensions in an equivalent luminaire, using a filament lamp as the light source. Regardless of the choice of mounting in either the classical lamp or diodes 251, 252, 253, 254 as a light source, said module 1 remains completely unchanged in terms of mounting dimensions, design and manufacturing technology. On the other hand, the complementary module 2 is available either in the diodes 251, 252, 253, 254 (Fig. 1 or 2) or in the classical version, where the lamp housing is fitted in the corresponding housing and the housing is closed from the rear by The complementary module 2 can then be exactly the same in both embodiments, which means, of course, that despite the same external dimensions of the two modules 1, 2, therefore, regardless of the choice of the light source, the fitting dimensions are always the same or. immutable.

Kadar je k svetlobnemu modulu 1 priključen komplementarni modul 2, v katerem so kot svetlobni vir vgrajene diode 251, 252, 253, 254, slednje segajo v območje reflektorja. Toplota, ki se generira v območju vezja 25 z diodami 251, 252, 253, 254, se zahvaljujoč prevodnosti stene 200 okrova 20 komplementarnega modula 2 prenaša na zrak, ki je na voljo v omenjenih prehodih 202, pri čemer je zahvaljujoč prisotnosti omenjenih reber 201 med prehodi 202 površina za prestop toplote z okrova 20 na okoliški zrak v območju prehodov 202 še v znatni meri povečana. Kadar je celoten okrov 20 komplementarnega modula 2 v zadostni meri toplotno prevoden, se preko razpoložljivih območij na obodu okrova 20 in tudi preko omenjenih reber 201 preostala, na okoliški zrak v prehodih 202 neoddana toplota prevaja proti kovinskemu pokrovu 24, ki v takem primeru prestavlja še dodaten prenosnik toplote z modula 2 na vsakokrat razpoložljiv okoliški zrak za svetilom.When a complementary module 2 is connected to the light module 1 in which diodes 251, 252, 253, 254 are mounted as the light source, the latter extend into the reflector region. The heat generated in the area of the circuit 25 by diodes 251, 252, 253, 254 is transmitted to the air available in said passages 202, thanks to the presence of said ribs 201, due to the conductivity of the wall 200 of the complementary module 2 housing 20. during passages 202, the heat transfer surface from the enclosure 20 to the ambient air in the pass passage 202 is further enlarged. When the entire casing 20 of complementary module 2 is sufficiently thermally conductive, residual heat is transmitted to the surrounding air in passages 202 through the available areas at the circumference of the casing 20 and also through the said ribs 201, which in this case reposition additional heat exchanger from Module 2 to the ambient air available behind the lamp at each time.
