Description:
MULTIFUNCTIONAL LAMP FOR MOTOR VEHICLE

The present invention relates to vehicles and, respectively, vehicle lightning and signalling equipment, particularly to headlamps and fog lamps, and more particularly to a lamp which in addition to lighting the section in front of the vehicle is also provided for lighting other sections, such as a so called multifunctional lamp being capable to carry out either simultaneously or occasionally different functions and, therefore, serves as a headlamp with integrated high beam and/or low beam and/or front position lamp (i.e. parking light) and/or direction indicator and/or cornering lamp, or as a fog lamp with integrated cornering lamp, for example, and similar.

The present invention is based on a problem how to create a multifunctional lamp for motor vehicle with a possibility, without intervening with the lamp structure itself or, optionally, also with minor intervention in the sense of the replacement of individual components, to regulate key optical features and, thus, to alter operating each lighting function of the lamp.

The applicant is aware of different multifunctional lamps with motor vehicles, which are capable either selectively or simultaneously to operate several lighting functions such as the function of a low or high beam, a direction indicator, a daytime running lamp, a cornering lamp and similar. It is typical for known solutions of the kind that each light source provided for generating light beams which reflect from each corresponding reflective surface of the reflector to the area in front of/behind/along a vehicle and thus provided for carrying out certain function, is supplied from its own power source. The light source for carrying out certain lighting function is either an incandescent light bulb, in particular a halogen bulb, such as with the lamp according to EP 2 419 672, or a light emitting diode (LED) and, respectively, a plurality of LEDs mutually connected to a suitable electric circuit, such as with the lamp according to SI 24567 A, for instance. Installing each of the sources of electricity intended to supply each of the light sources available is connected with certain costs and, simultaneously, the larger number of the components represents also the increasing possibility of failure. In case LEDs are used as the light source, also replacement of the light source may cause problems. In particular, known lamps does not allow adjusting operation of each lighting functions without interfering with the design of the lamp itself. The invention refers to a multifunctional lamp for a motor vehicle. Said lamp comprises a body having at least one light permeable wall, and inserted inside said body at least one reflector having at least two reflective surfaces. Furthermore, said lamp comprises a generally replaceable light source installed in said body, said light source being configured for cooperation with each available reflective surface of the reflector in a manner that the light beams generated by said light source and directed towards said reflector redirect at said reflective surfaces of the reflector toward the light permeable wall and through the latter into each corresponding area in the front or behind or along the vehicle.

It is provided according to the present invention that said light source is formed as a linear carrier, at least one series of mutually uniformly spaced light elements being attached thereto, each of said light elements being electrically connected to the control unit which is electrically connectable to the power source, and configured in a manner that operation of each light element or certain predetermined groups of the light elements can be programmed in the sense of cooperation of said each light element or certain predetermined groups of the light elements with each corresponding reflective surfaces of the reflector, thus carrying out individual predetermined lighting function of the lamp. Each light source is preferably represented as a light emitting diode (LED).

Optionally, said light source is inserted either in longitudinal or transversal direction of the lamp.

Moreover, said light source may resemble at least approximately rectangular form, when viewed from the side, the number of available series of light elements being either equal or less than the number of longitudinal surfaces of the light source formed as a linear carrier.

Alternatively, said light source may resemble a polygonal form, when viewed from the side, the number of available series of light elements being either equal or less than the number of longitudinal surfaces of the light source formed as a linear carrier.
