Definitions

  • the invention relates to lighting systems of vehicles. State of the Art
  • Headlamps/headlights are used for lighting the road while driving in two different angles, i.e. in the form of main beam or dipped/low beam.
  • headlamp systems with various characteristics which change angle in horizontal direction while cornering, which can adjust the distance and direction of the headlight in order to provide a better night vision according to the position of the vehicle approaching from the opposite direction, and which are capable of changing lighting distance of the headlamp according to vehicle speed, or allow the driver to adjust it.
  • the common point of all these systems is that they are all related to directing the headlight beam.
  • MEMS Microelectromechanical Systems
  • MEMS Microelectromechanical Systems
  • the electronic circuit component sensing the movement when a mobile phone is rotated sideways is an MEMS device.
  • projection systems that are produced with MEMS devices called Digital Micromirror Devices (DMD) and control the light only by reflecting it.
  • DMD Digital Micromirror Devices
  • components which can be mounted in a printed circuit board, which are in the form of an electronic component and comprise light reflecting/inhibiting/directing components therein, can be produced with MEMS technique. These are moved by electric signals applied in the chip, thereby controlling light beams.
  • Controlling of the light beams include inhibiting/blocking or allowing the light, reflecting, focusing, and distributing it, or such interventions. These interventions can be made in all, or a part of the light beam coming to the device, depending on the properties of the MEMS device being used. MEMS devices make it possible to make these interventions in micro scale.
  • the invention developed by being inspired by the existing conditions, aims to solve the aforementioned drawbacks.
  • the object of the invention is to perform light directing processes with MEMS device or any other light source, instead of, or together with some of, the following which enable the light in headlamps to be directed; double-filament lamps for short-long distance lighting or individually grouped LEDs, various reflective systems and/or moveable mechanisms inside the headlamp, reflectors, mechanical components made of sheet metal or plastic, and solenoids or motors moving them.
  • Another object of the invention is to allow the light to be directed from the point where it is produced inside the headlamp, unlike the current techniques. Hence, it eliminates the disadvantages of the current techniques and provides novelties in terms of headlamp design and use.
  • the subject matter of the invention is the vehicle lighting system, particularly vehicle headlamp, which is produced using MEMS device, which enables the light source and the light emitted by the light source to be controlled. It will be possible in the thus produced headlamps to control light beams as desired while driving. Further, thanks to the MEMS device or MEMS chip, the sensed light intensity will be increased or decreased optionally, by switching on and off the light in a frequency which cannot be detected by human eye. Since vehicle lighting systems, particularly headlamps, will not comprise big-size mechanisms and reflectors, they will be smaller and less costly, at the same time more functional. Making the headlamps smaller in size will allow changes in vehicle designs, as well.
  • Such a lighting system can be used in all exterior lamps of the vehicles. For example, it is possible to signal by switching on and off the light, without requiring any flasher, in signal lamps. Or, a more effective data communication will be achieved by changing the light intensity or switching on/off frequency of the stop lamp such that it will be sensed by human eye, according to the braking force in rear stop lamps.
  • the lighting system which is used in vehicles in automotive industry and comprises a light source and an MEMS device or MEMS chip controlling the light emitted by the light source and produced as a single piece with the light source, or separately therefrom, is developed.
  • a preferred embodiment of the invention allows the light emitted by the light source to be sent onto the MEMS device by means of the focusing and/or reflecting members located between the light source and MEMS device.
  • the light beam from the MEMS device can be passed through a separate lens/reflecting assembly according to the needs arising from different headlamp designs.
  • Another object of the invention is directing and/or blocking the light partially or fully, which is emitted from one or multiple light source, as being different from the embodiments which includes DMD devices providing reflecting of the light.
  • Fig. 1 is the representative view of the preferred embodiment of the vehicle headlamp according to the invention.
  • Fig. 2 is the representative view of an alternative embodiment of the vehicle headlamp according to the invention. Description of Part References
  • MEMS Microelectromechanical systems
  • the lighting system (1) described in the detailed description will be used in all exterior lighting systems of the vehicles, particularly in vehicle headlamps, in automotive industry.
  • the lighting system (1) consists of an MEMS device (3) and a light source (4).
  • the MEMS device (3) may be in the form of MEMS chip; and in the preferred embodiment of the invention, MEMS chip is preferably used as the MEMS device (3).
  • MEMS chip can be produced using the known production techniques in the art.
  • the light source (4) may as well be produced with the existing production techniques. LEDs, light bulbs, or any other electric light source known in the art can be used as the light source.
  • the expression light beam (2) is used for the light to be directed and/or formed, while the light beam (2) should be considered as a 3-dimensional cone.
  • one or more MEMS chip/s or light source/s (4) can be produced with the existing production techniques; alternatively they can be mounted to one another subsequently, or the two can be produced as a single piece.
  • the preferred operating principle of the lighting system (1) made up of MEMS chip and light source (4) is as follows: Light is emitted by the light source (4) used as the source of light. Afterwards, the light coming to the MEMS chip is controlled here as desired, i.e. by being blocked and/or directed and/or focused and/or reflected and/or distributed, or by being subject to similar applications made on the light, and leaves the lighting system (1) in the form of light beam (2).
  • MEMS chip is electrically controlled. The control can be performed by the driver or the computer system of the vehicle. MEMS chip has the following functions on the headlamp (for some of these, the MEMS device is required to be digitally controlled):
  • the distance and direction of the headlamp is adjusted according to braking, acceleration, vehicle approaching from the opposite direction, or road lighting level.
  • the brightness of the light emitted by the light source (4) which is sensed from the outside can also be adjusted.
  • the lighting system (1) according to the invention will also be used, apart from the vehicle headlamps, in signal lamps, parking lamps, stop lamps, day time running lamps (DRL) and in siren lamps of police cars, ambulances, fire trucks, rescue vehicles, civil defense vehicles, etc.
  • the light intensity of the stop lamp will be increased or decreased in accordance with the braking force, thanks to the lighting system (1).
  • switching on frequency of the stop lamp will be increased and decreased.
  • the MEMS device (3) may be much smaller in size than the light source (4).
  • the light emitted by the light source (4) is required to be focused on the MEMS device (3).
  • This requires locating control members allowing the light emitted by the light source (4) to be controlled, or more particularly focusing members (6) and/or reflecting members (5), between the light source (4) and MEMS device (3). Therefore, in alternative embodiments of the invention, focusing members (6) and/or reflecting members (5) are used for these processes (Fig. 2).
  • a lens may be used as the focusing member (6) while a mirror, reflector, etc. may be used as the reflecting member (5).
  • a lens, reflector, etc. can be used to that end.
