Description

HELLA SATURNUS SLOVENIA,

Manufacture of lighting equipment for motor vehicles and other vehicles, d.o.o.

Motor vehicle multifunction lamp

The invention falls within the field of vehicles or vehicles. lighting and signaling equipment for vehicles, in particular the headlamps and front fog lamps, and in particular refers to a lamp which, in addition to illuminating the area in front of the vehicle, is intended to illuminate other areas, namely a so-called multifunctional lamp capable of simultaneously or at least occasionally performing different functions and can therefore serve as a headlamp, with integrated high beam and / or dipped beam and / or parking lamp and / or direction indicator and / or angle lamp, or e.g. as a fog lamp with integrated corner light, or the like.

The invention is based on the problem of how to design a multifunctional motor vehicle light, in which without prejudice to the design of the lamp itself, and optionally with minor interventions in terms of replacement of individual components, it is possible to adjust the key optical properties and thereby adjust the operation of the individual lighting light functions.

The Applicant is aware of the various multifunctional lamps for motor vehicles that are capable of optional, simultaneous, multiple lighting functions, e.g. low beam or high beam function, direction indicator, daylight, corner light or the like. Such known solutions are characterized by the fact that each light source intended to generate light rays reflecting from the respective reflecting surface of the reflector into the area before / behind / next to the vehicle, and thus to perform a specific function, is electrically powered from own source of electricity. A light source for performing a given luminous function is either a filament lamp, in particular a halogen lamp, such as a lamp. for a light according to EP 2 419 672, or a light-emitting diode (LED) or a series of interconnected to a corresponding circuit of electrically connected LEDs, such as a for SI according to 24567 A. The installation of each of the electrical sources intended to supply each of the available light sources is associated with a certain cost, but at the same time a greater number of components means a greater likelihood of failure. When using diodes as a light source, replacing the light source is also problematic. In particular, such lamps do not allow the adjustment of the operation of individual lighting functions without prejudice to the design of the lamp itself.

The invention relates to a multifunctional motor vehicle light. Such a light comprises a housing with at least one light-permeable wall, and at least one reflector with at least two reflecting surfaces is inserted inside said housing (1). The luminaire further comprises in this housing an integrated and generally interchangeable light source adapted to cooperate with the available reflector surfaces of the reflector in such a way that the light rays generated by said light source and directed toward said reflector on said reflector surfaces redirect the light-transmitting casing wall and through the latter into the appropriate area in front of or behind the vehicle or next to the vehicle.

According to the invention, said light source is designed as a line carrier on which at least one set of uniformly spaced luminaires are attached, each of which is electrically connected to a control unit that is electrically connected to the power source and adapted to the possibility of programming the operation of individual luminaires or predetermined groups of said luminaires in terms of the cooperation of said individual luminaires or predetermined groups of said luminaires with the respective reflecting surfaces of the reflecting surfaces of the reflector and thereby performing individual predetermined luminous functions of the luminaire. Each light element is preferably a light emitting diode (LED).

Said light source is optionally inserted into the housing either in the longitudinal or transverse direction of the lamp.

Further, said light source in the profile may be at least approximately rectangular, and the number of available sets of luminaires is either equal to or less than the number of longitudinal planes as the line carrier of the designed light source.

Alternatively, said light source in the profile may be formed as a polygon, the number of available sets of luminaires being either equal to or less than the number of longitudinal planes as a line carrier of the designed light source.

The invention will now be explained in further detail by way of examples and in connection with the accompanying drawing showing

In FIG. 1 and 2 is a schematic illustration of an embodiment of a multifunctional motor vehicle light comprising a housing 1 with at least one light-permeable wall 11. A reflector 2 is inserted inside said housing 1, optionally comprising four reflecting surfaces 21, 22, 23, 24, which are each adapted to perform different lighting functions, e.g. dipped beam, high beam, corner lamp, direction indicator, position light or fog lamp.

In said housing 1, a light source 3 is incorporated, which as such is generally interchangeable on the one hand and, on the other hand, adapted to cooperate with the reflector surfaces 21, 22, 23, 24 available at each time, in such a way that the light rays generated by said light source 3 and directed toward said reflector 2, in said reflecting surfaces 21, 22, 23, 24 of the reflector 2 are directed towards the light-permeable wall 11 of the housing 1 and through the latter into the respective area in front of or behind the vehicle. or next to the vehicle.

According to the invention, it is proposed that said light source 3 be designed as a line carrier on which at least one set of light elements 31, 32, 33, 34, 35, 36, 37, 38 are spaced apart; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38', each of which is electrically connected to a control unit 4 which is electrically connected to a power source 5. Said control unit 4 is further adapted to program the operation of individual luminaires 31, 32, 33, 34, 35, 36, 37, 38; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38' or the predetermined groups of said light elements 31, 32, 33, 34, 35, 36, 37, 38; 3Γ, 32 ′, 33 ′, 34 ′, 35 ′, 36 ′, 37 ′, 38 ′ in terms of the cooperation of said individual luminaires 31, 32, 33, 34, 35, 36, 37, 38; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38' or the predetermined groups of said light elements 31, 32, 33, 34, 35, 36, 37, 38; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38' with the respective reflecting surfaces 21, 22, 23, 24 of reflector 2 for the purpose of performing the individual predetermined luminous functions of the lamp.

Furthermore, it is provided according to the invention that the respective light element 31, 32, 33, 34, 35, 36, 37, 38; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38' are the LEDs whose cathode and anode are each electrically connected to said control unit 4 (Fig. 6). In the example shown in FIG. 1 and 2, the light source 3 is inserted in the housing 1 in the transverse direction of the lamp.

In FIG. 3 and 4, a further embodiment is presented in which the light source 3 is inserted into the housing 1 in the longitudinal direction of the lamp and is adapted to cooperate with two reflectors 2, 2 '.

Said light source 3 is, in any case, available in the form of a rod-shaped beam, with the possibility of realizing its transverse profile and the installation of individual sets of light elements 31, 32, 33, 34, 35, 36, 37, 38; 31 ', 32', 33 ', 34', 35 ', 36', 37 ', 38' may differ from each other.

Thus, in the simplest embodiment, the light source 3 in the profile is at least approximately rectangular, the number of available sets of light elements 31, 32, 33, 34, 35, 36, 37, 38; 3Γ, 32 ′, 33 ′, 34 ′, 35 ′, 36 ′, 37 ′, 38 ′ is either equal to or less than the number of longitudinal planes as the line carrier of the designed light source 3.

On the other hand, it is similar to the embodiments of FIG. 1 and 2 and FIG. 3 and 4, the light source 3 in the profile can be formed as a polygon, with the number of available sets of lighting elements 31, 32, 33, 34, 35, 36, 37, 38; 3Γ, 32 ′, 33 ′, 34 ′, 35 ′, 36 ′, 37 ′, 38 ′ even in this case may be either equal to or less than the number of longitudinal planes as the line carrier of the designed light source 3.

The advantage of this type of lighting is the wide possibility of adjusting the luminaire for performing various lighting functions by means of the universal light source 3 in the universal housing 1 or by means of a single reflector 2 with the respective reflecting surfaces 21, 22, 23, 24, and optionally by means of fitting a different reflector 2 or incorporating a different light source 3 into the same housing 1.
