Abstract

An invention pertains to the motor vehicles, particularly to the supplementary or complementary lower beam headlights for additional lighting of the carriageway. Its purpose is to facilitate the driving for the most part at dark time all around the clock, especially at nighttime and conditions of limited visibility. There is offered to provide the vehicle's lower beam headlights with at least one supplementary lower beam luminaire, located separately of vehicle's headlights, or to provide at least one headlight with complementary lower beam radiator, inserted into vehicle's head lights as an additional light emitting section, said supplementary luminaire or complementary section being assembled of standard industrial lower beam headlights and lighting fittings by turning the body of luminaire by an angle up to 90 DEG with an longitudinal axis of vehicle together with the light radiating insert as a unit. The supplementary luminaire offered is supposed to form the light beam having the transition border-plane from light to dark strongly marked. Said border-plane is supposed to be coinciding with a vertical plane that does not intersect the centre line of carriageway thus excluding glaring of persons driving from the opposite direction. The luminaire offered can be combined with the vehicle's rear-view mirror's holder providing the possibility of somewhat turning thereof.

Description

Automobiļu tuvas gaismas papildlukturis(-i)Dipped-beam headlamp (s)

Izgudrojuma aprakstsDescription of the Invention

Izgudrojums attiecas uz autotransporta ārējās apgaismes sistēmām, konkrēti - uz autoceļu braucamās joslas papildus izgaismošanu tumšā diennakts laikā, kad tuvās gaismas lukturi to nenodrošina, bet tālās gaismas lukturus lietot nav iespējams.The invention relates to external lighting systems for motor vehicles, in particular to the additional illumination of a carriageway at night, when the dipped-beam headlamps do not provide it, but the main-beam headlamps cannot be used.

Straujā autotransporta skaita palielināšanās uz autoceļiem ir novedusi pie tā, ka nepārtrauktās pretimbraucošo automobiļu plūsmas dēļ tālās gaismas lietošana ir ierobežota. Savukārt tuvās gaismas lukturi tumsā ceļu izgaismo tikai 25-40 metru attālumā automobiļa braukšanas virzienā, ko paredz ceļu satiksmes noteikumi, kaut gan tas ir nepietiekami drošai braukšanai. Automobiļa apstāšanās ceļu uz sausas, horizontālas brauktuves aprēķina pēc formulas - ceļš vienāds ar ātrumu, dalītu ar 10, un dalījums celts kvadrātā. Tātad, ja ātrums ir 60 km/h, apstāšanās ceļš ir 36 metri, ja ātrums ir 70 km/h, tad apstāšanās ceļš ceļš ir 49 metri. Uz slidenas brauktuves apstāšanās ceļš vismaz divreiz lielāks. Kā redzams, apstāšanās ceļš lielāks kā tuvās gaismas lukturu un miglas lukturu izgaismotais attālums. Statistika liecina, ka 38-40% no visām avārijām notiek tumšā diennakts laikā sliktās redzamības dēļ. Tātad, braucot galvenokārt ar ieslēgtiem tuvās gaismas lukturiem, kaut gan naktīs brauc skaitliski daudz mazāk automāšinu kā dienā, 25-40 metri, ko izgaismo tuvās gaismas vai miglas lukturi, ir par maz pat vieglajiem automobiļiem, bet smagajiem automobiļiem tas ir pilnīgi nepietiekami.The rapid increase in the number of road vehicles on the road has led to the restriction of the use of high beam due to the continuous flow of oncoming vehicles. Dipped-beam headlamps, on the other hand, illuminate the road in the dark only 25-40 meters in the direction of the car, even though it is not safe enough for driving. The stopping distance of a car on a dry, horizontal carriageway is calculated by the formula: the road equals the speed divided by 10 and the division is squared. So for a speed of 60 km / h, the stop is 36 meters, for a speed of 70 km / h, the stop is 49 meters. On a slippery carriageway, the stopping distance is at least twice as high. As can be seen, the stopping distance is greater than the illuminated distance between the dipped-beam headlamps and the fog lamps. Statistics show that 38-40% of all crashes occur during dark hours due to poor visibility. So while driving with low beam headlamps on, even though there are far fewer cars driving at night than in the daytime, 25-40 meters illuminated by low beam or fog lamps are not enough even for passenger cars, but not enough for heavy vehicles.

Līdzšinējo zināmo tehnikas līmeni automobiļu ārējās apgaismes jomā raksturo tālās gaismas, tuvās gaismas un miglas lukturu pielietojums dažādās kombinācijās realizācijas un izvietojuma ziņā. Ir tuvās gaismas un miglas lukturi, kas veido un projecē uz ceļa automobiļa priekšā 25-40 metru attālumā gaismas-ēnas robežu, perpendikulāru automašīnas garenasij, vai staru kūļa frontālās plaknes šķēlumā veido horizontālu līniju, kas 1. un 2. figūra parādīta kā līnija H-H. Jaunākais zināmais tehnikas līmenis šajā jomā ir rūpnīcas Hella Vācijā ražotie lukturi Micro DE (skat, izdevniecībā Baltika izdoto žurnālu Auto, Nr. 12, 1999, 9. Ipp.), kas izvēlēti par prototipu izgudrojuma realizācijai.The state of the art to date in the field of automotive exterior lighting is characterized by the use of high-beam, dipped-beam and fog lamps in various combinations in terms of implementation and positioning. There are dipped-beam and fog lamps which form and project on the road ahead of the car at a distance of 25-40 meters from the light-shadow line perpendicular to the longitudinal axis of the car or form a horizontal line in the frontal plane of the beam. . The latest state of the art in this field is the Micro DE lamps manufactured by the Hella factory in Germany (see Auto magazine issue No. 12, 1999, p. 9 by Baltika), chosen as a prototype for the implementation of the invention.

Neviens no minētajiem lukturiem neveido staru kūli ar gaismas-tumsas robežu vertikālajā plaknē vai tuvu tai, izejošu no luktura. Tie nav paredzēti novietošanai automobiļa kreisajā pusē tā, lai staru kūlis ar tā gaismas-tumsas robežu šaurā leņķī attiecībā pret braukšanas joslas malām tiktu virzīts uz braucamās joslas labās puses apmali. Tie nav tik jaudīgi, lai izgaismotu ceļa braucamo joslu pietiekošā attālumā drošai braukšanai.None of these lamps shall produce a beam having a light-dark line in, or close to, the vertical plane coming out of the lamp. They are not intended to be parked on the left side of the vehicle so that the beam with its light-dark border at a narrow angle to the lane edges is directed to the right side of the lane. They are not powerful enough to illuminate the road lane for safe driving.

Izgudrojuma mērķis ir braukšanas drošības un ērtību palielināšana uz autoceļiem, papildus esošajai automobiļu tuvai gaismai izveidot pēc vajadzības uzstādāmu un ieslēdzamu apgaismojumu, kas izgaismo braucamo joslu tālāk, bet nežilbina pretimbraucējus.The purpose of the invention is to increase driving safety and comfort on the roads, and to provide, in addition to existing automotive dipped beam, on-demand illumination which can be illuminated further but does not dazzle oncoming drivers.

Lai sasniegtu minēto mērķi, piedāvāts papildus uzstādīt vismaz vienu papildlukturi 2, kas vertikālajā plaknē vai tuvu tai veido gaismas staru kūli, norobežotu no ceļa ass puses (skat. 5. figūrā līnijas AB un CD). Lukturis 2 vienā no izgudrojuma realizācijas variantiem (formulas punkti no 1. līdz 3. punktam) novietots automobiļa kreisajā pusē (5. fig.) ar iespēju to nedaudz grozīt tā, lai tā veidotā gaismas-tumsas robeža aptuveni 200 - 300 metrus automobiļa priekšā, šķērsojot braucamās joslas labo malu, atkarībā no situācijas pietiekoši labi izgaismotu braucamās joslas daļu uz ceļa apmales pusi, nežilbinot pretimbraucējus. Lukturis 2 citos izgudrojuma realizācijas variantos novietots automobiļa labajā pusē (4. un 5. formulas punkti) vai abās pusēs (6. formulas punkts). Iepriekš aprakstītais lukturis(-i) lietojams pie ieslēgtām tuvām gaismām vai miglas lukturiem, tas ar atsevišķu slēdzi ir ieslēdzams vai izslēdzams pēc vajadzības, tāpat ir pieliekams vai noņemams un, pielietojot pagarinātu vadu, lukturi ir iespējams izmantot arī kā pārnēsājamu gaismas ķermeni, veicot automobiļa remontu tumšā diennakts laikā uz ceļa, kā arī ir iespējams izgaismot apkārtni. Šajos izgudrojuma realizācijas variantos izmantots prototipā aprakstītais lukturis, bet tikai ar to atšķirību, ka luktura korpuss pagriezts par tik, lai gaismas-tumsas robeža pagrieztos aptuveni par 90 grādiem, kā arī ir palielināta gaismas stara jauda. Smagajām automašīnām lukturi var nostiprināt kreisajā un/vai labajā pusē pie spoguļa kronšteina, vieglajām to var apvienot ar kreisās un/vai labās puses aizmugures spoguļa turētāja korpusu un ir iespējams to nedaudz grozīt. Luktura pieslēgšanai pie elektrobarošanas jāierīko rozete un slēdzis luktura ieslēgšanai vai izslēgšanai.In order to achieve this objective, it is proposed to additionally mount at least one additional lamp 2 which forms a beam of light in the vertical plane or close to the axis of the road (see lines AB and CD in Figure 5). Headlamp 2 in one embodiment of the invention (formula points 1 to 3) is located on the left side of the car (Fig. 5) with the possibility of being slightly modified so that it has a light-dark border of about 200-300 meters in front of the car, crossing the right edge of the carriageway, depending on the situation, a sufficiently well-lit part of the carriageway to the side of the road, without dazzling the oncoming traffic. The lamp 2 in other embodiments of the invention is located on the right side of the car (points 4 and 5 of the formula) or on either side (point 6 of the formula). The headlamp (s) described above can be used with the dipped-beam headlamps or the dipped-beam headlamps, and can be switched on or off as needed with a separate switch, and can also be used as a portable light when using an extended cord. repairs during the dark hours on the road, and it is possible to illuminate the surroundings. These embodiments of the invention use the lamp described in the prototype, but with the exception that the lamp body is rotated so that the light-dark border rotates about 90 degrees, and the light beam power is increased. For trucks, the headlamp can be mounted on the left and / or right side of the mirror bracket, for light vehicles it can be combined with the left and / or right rear mirror holder body and can be slightly modified. To connect the lamp to the power supply, it must be fitted with a socket and a switch for switching the lamp on or off.

Vēl citos izgudrojuma realizācijas variantos (7. un 8. formulas punkti) tuvās gaismas papildluktura(-u) funkcijas pilda automobiļa miglas lukturis(-i), kuru radītā staru kūļa gaismas-tumsas robeža, tos pagriežot aptuveni par deviņdesmit grādiem, sakrīt ar vertikālo plakni vai ir tuvu tai un braukšanas virzienā vajadzīgajā attālumā šķērso braucamās joslas labo malu.In still other embodiments of the invention (formulas 7 and 8), the functions of the dipped-beam headlamp (s) are accomplished by an automotive fog lamp (s) having a beam-to-dark cut-off of about 90 degrees to the vertical. plane or close to it and crosses the right edge of the carriageway at the required distance in the direction of travel.
