Automobile headlight assembly
A headlight assembly for an automobile comprising a left region and a right region, the headlight assembly being configured to reduce an intensity of a light beam when an oncoming automobile is detected, is described. The headlight assembly includes, at least one light source, at least one light detector configured to detect the oncoming automobile and generate a signal, and a control module configured to receive the signal from the light detector, and reduce the intensity of the light beam. A method for reducing the intensity of a light beam of a headlight assembly for an automobile when an oncoming automobile is detected, is also described.
1. A headlight assembly for an automobile comprising a left region and a right region, the headlight assembly being configured to reduce an intensity of a light beam when an oncoming automobile is detected, comprising:
at least two high beam sources;
at least two low beam sources;
at least two light detectors configured to detect the oncoming automobile and generate a signal, wherein each of the light detector is mapped to a respective high beam source;
a control module configured to receive the signal from the at least one light detector, and reduce the intensity of the light beam by changing beam spread, wherein to change the beam spread, the control module is configured to selectively switch off at least one high beam light source corresponding to the at least one light detector from which the oncoming vehicle is detected.
2. The headlight assembly of claim 1 , further comprising at least two light sources positioned at the left region and right region of the headlight assembly.
3. The headlight assembly of claim 1 , wherein the at least two light detectors is positioned in the left and right regions of the headlight assembly.
4. A method for reducing an intensity of a light beam of a headlight assembly for an automobile, the method comprising the steps of:
detecting, by at least one light detector, an oncoming automobile;
generating a signal by the at least one light detector;
receiving, at a control module, the signal generated by the at least one light detector;
conditioning, by the control module, the signal to produce a conditioned signal;
transmitting, by the control module, the conditioned signal to at least one light source, wherein each of the light detector is mapped to a respective light source; and
reducing the intensity of the light beam by changing beam spread, wherein changing the beam spread comprises selectively switching off at least one light source corresponding to the at least one light detector from which the oncoming vehicle is detected.
5. The method of claim 4 , wherein detecting the oncoming automobile is carried out by means of at least two light detectors positioned at the left and right regions of the headlight assembly.
6. The method of claim 4 , wherein selectively switching off the at least one light source comprises selectively switching off at least one high beam source.
7. A headlight assembly for an automobile comprising a left region and a right region, the headlight assembly being configured to reduce an intensity of a light beam when an oncoming automobile is detected, comprising:
at least two light sources;
at least two light detectors configured to detect an oncoming automobile and generate a signal, wherein each of the light detector is mapped to a respective light source;
a control module configured to receive the signal from the at least two light detectors, and reduce the intensity of the light beam by changing beam spread, wherein to change the beam spread, the control module is configured to selectively switch off at least one light source corresponding to the at least one light detector from which the oncoming vehicle is detected.
