The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
Present disclosure, in general, relates to a field of automobiles. Particularly, but not exclusively, the present disclosure relates to a headlamp unit. Further, embodiments of the present disclosure relates to a light deflection device for the headlamp unit and a method for deflecting light beam from the headlamp unit.
BACKGROUND OF THE DISCLOSURE
Modern motor vehicles are equipped with a wide array of illumination devices that illuminate the exterior and interior of the vehicle. For example, exterior vehicle lighting devices perform stop lamp functions, tail lamp functions, headlamp functions, running light functions, dynamic bending light functions and fog lamp functions. Numerous studies have found that night time visibility is a key to highway safety.
To improve roadway safety, governments and other entities promulgate some form of safety regulations that specify motor vehicle lighting requirements. Such regulations help to ensure adequate illumination of the roadway and visibility of motor vehicles on the road so that their presence is apparent and their signals are understood in daylight, in darkness and in conditions of reduced visibility.
High intensity light beam from an oncoming vehicle often reaches eyelevel of a driver riding a vehicle, which may causes invisibility of oncoming vehicles obstructions and the like, especially during night. Some light regulation systems and devices are often employed to avoid such instances and/or selectively reduce intensity of light beam. Such conventional light deflection mechanisms employs an array of LEDs as a light source to regulate light intensity from the headlamp unit, where, some of the LEDs in the array are switched ON/OFF selectively based on illumination requirements. Such systems are complex and may reduce visibility of the path to an extent which is not desirable. Further, such control systems are often expensive due to complex operation and components required for regulating light beam.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional mechanisms.

Figures 1a is an exemplary embodiment of the present disclosure which illustrates a vehicle (200). The vehicle (200) includes two headlamp units on either sides. In an embodiment, each headlamp unit (201) may emit light in a low light beam configuration which may be referred to as lower or dipped beam. The headlamp unit (201) may emit light in a high light beam configuration which may be referred to as main or driving light beam with high intensity compared to low light beam. Typically, the low light beam is used whenever a vehicle (200) is directly ahead of the vehicle (200) and/or whenever an oncoming vehicle B is approaching the vehicle (200) from an opposite direction. Whereas, high beam light is used to illuminate a wider and longer region of path to be traversed by the vehicle (200). In an embodiment, each headlamp unit (201) comprises at least one light source to emit the light beam, at least one reflector (201a) to reflect the light beam from the light source in front of the vehicle (200) and at least one transparent cover to allow the light beam from the light source in front of the vehicle (200).
The vehicle (200) includes at least one deflection device (2) connectable to each of the headlamp unit (201). Each deflection device comprises one or more sensors (1) disposed on a

portion of the vehicle (200). In an embodiment, the sensors (1) are disposed on either sides of the headlamp unit (201) in a spaced apart configuration on a front portion of the vehicle (200) as can be seen in Figure 1a. In the illustrative embodiment, three sensors (1) are positioned one each side of the vehicle (200) in spaced apart configuration, where the sensors (1) are positioned in a stepped or height wise manner i.e., one sensor proximal to the headlamp unit (201), one sensor proximal to a windshield of the vehicle (200), and one sensor on roof portion of the vehicle (200) for accurate detection of predetermined light beam from all parts [frontal portion of the vehicle] from the oncoming vehicle B.
The vehicle (200) is illustrated with three sensors (1) on both sides for the sake of explanation and the same shall not be considered a limitation, as the number and configuration of the sensors (1) may be varied based on the requirement. In an embodiment, the sensors (1) are positioned facing forward to detect predetermined light from the oncoming vehicle B and avoid detection of other light sources such as light from lamp posts, tunnel lights and the like. The sensors (1) are configured to detect predetermined amount of light beam intensity from an oncoming vehicle B. In an embodiment, the sensors (1) may be positioned on the vehicle (200) by means of fasteners, adhesives and the like.
Referring now to Figures 2a to 2c, the light deflection device includes a base plate (21) connectable to a reflector (201a) of the headlamp unit (201). The base plate (21) is structured to receive at least one actuator (22) and at least one deflector (23) is operatively coupled to the actuator (22). In an embodiment, the reflector (201a) is defined with at least one aperture along a vertical axis (AA’) of the headlamp unit (201) as can be seen in Figure 2c. The actuator (22) is configured to selectively displace the deflector (23) through the aperture to deflect light from the headlamp unit (201). In an embodiment, the profile of the aperture may be defined based on shape of the deflector (23) to allow displacement of the deflector (23). In the illustrative embodiment, the deflector (23) is configured to slide forward and rearward relative to the base plate (21) based on actuation of the actuator (22). The deflector (23) is configured to deflect light from the headlamp unit (201) upon forward movement as can be seen in Figures 1b and 2b and is configured to allow light upon rearward movement as can be seen in Figure 2a. In an embodiment, the vehicle (200) is depicted with a single light deflection device for each headlamp, while the number of deflection devices may be increased based on requirement of the vehicle (200). In the illustrative embodiment, the right side headlamp is depicted with light deflection device positioned on a right side of the light source and a left side headlamp is

depicted with light deflection device positioned on a left side of the light source as can be seen in Figure 1a. The light deflection devices on either side of the vehicle (200) may operate independent of each other or may operate synchronously based on requirement.
Referring now to Figure 3, each light deflection device comprises a control unit (3) communicatively coupled to the sensors (1) and the actuator (22). In an embodiment, the control unit (3) is communicatively coupled to the body control module of the vehicle (200) to receive at least one signal corresponding to light beam state of the headlamp unit (201). The at least one signal from the body control module of high light beam. The control unit (3) is configured to receive at least one signal from the sensors (1) corresponding to a light intensity value of the light beam from the oncoming vehicle B. The control unit (3), then compares the light intensity value received from the at least one signal with a threshold light intensity value, when the control unit (3) receives signal indicative of high light beam of the headlamp unit (201).

The control unit (3) may transmit at least one actuation signal to the actuator (22) to displace the deflector (23) forward when the light intensity value is greater than the threshold light intensity value to deflect light.
Referring now to Figures 4a and 4b, the sensors (1) on right side of the vehicle (200) are configured to detect light from the oncoming vehicle B approaching from right as can be seen in Figure 4a. In such scenario, the deflector (23) deflects the light from the headlamp thereby avoiding exposure of high intensity light beam to the oncoming vehicle B as can be seen in Figure 4b upon receiving the actuation signal from the control unit (3). In an embodiment, the threshold light intensity value may correspond to a high beam light intensity that is required to temporarily blind a driver of the vehicle (200).
Later, the control unit (3) may transmit at least one actuation signal to the actuator (22) to displace the deflector (23) rearward to allow light when the light intensity value is less than the threshold light intensity value. The deflector (23) may allow light from the headlamp unit (201) when the light intensity value from the oncoming vehicle B is less than the threshold light intensity value, which may not cause temporary blindness or flash blindness of the driver in the vehicle (200) A. In an embodiment, the control unit (3) is configured to determine the headlamp unit (201) being exposed to light from the oncoming vehicle B based on corresponding sensor transmitting the signal. The control unit (3) then actuates the light

deflection device corresponding to the headlamp being exposed to the light from the oncoming vehicle B to deflect light from the corresponding headlamp unit (201). For example, the control unit (3) may actuate light deflection device corresponding to headlamp unit (201) on right side of the vehicle (200) when light from the oncoming vehicle B reaches the sensors (1) on right side of the vehicle (200) as can be seen in Figure 4b.
In an embodiment, the control unit (3) may be a centralised control unit (3) of the vehicle (200) or may be a dedicated control unit (3) to the system associated with the centralised control unit (3) of the vehicle (200).

The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
Referring now to figure 5, which is an exemplary block diagram illustrating a method for deflecting light beam from the headlamp unit (201) of the vehicle (200).
At block 301, the control unit (3) is configured to receive at least one signal from the one or more sensors (1) disposed on a front portion of the vehicle (200). The at least one signal corresponds to a light intensity value of the light beam from the oncoming vehicle B. In an embodiment, the control unit (3) is communicatively coupled to the body control module of the vehicle (200) to receive at least one signal corresponding to light beam state of the headlamp unit (201).
At block 302, the control unit (3), compares the light intensity value received from the at least one signal with a threshold light intensity value, when the control unit (3) receives signal indicative of high light beam of the headlamp unit (201) from the body control unit (3). In an embodiment, the threshold light intensity value may correspond to a high beam light intensity that is required to temporarily blind a driver of the vehicle (200).
At block 303, the control unit (3) actuates the at least one actuator (22) to selectively displace the at least one deflector (23) into the reflector (201a) to deflect the light beam of the vehicle (200). The control unit (3) may transmit at least one actuation signal to the actuator (22) to displace the deflector (23) forward when the light intensity value is greater than the threshold light intensity value to deflect light. In an embodiment, the sensors (1) on right side of the vehicle (200) are configured to detect light from the oncoming vehicle B approaching from right as can be seen in Figure 4a. In such scenario, the deflector (23) deflects the light from the headlamp thereby avoiding exposure of high intensity light beam to the oncoming vehicle B as can be seen in Figure 4b upon receiving the actuation signal from the control unit (3). Later, the control unit (3) may transmit at least one actuation signal to the actuator (22) to displace the deflector (23) rearward to allow light when the light intensity value is less than the threshold light intensity value. The deflector (23) may allow light from the headlamp unit (201) when the light intensity value from the oncoming vehicle B B is less than the threshold light intensity

value, which may not cause temporary blindness or flash blindness of the driver in the vehicle (200) A.
In an embodiment, the control unit (3) is configured to determine the headlamp unit (201) being exposed to the light beam from the oncoming vehicle B based on corresponding sensor transmitting the signal. Here it is important to note that the sensor is able to pick up the light beams that directly fall on the sensor based on light intensity. Usually, this light intensity is the one that is sharp and focused which may impinge directly on the sensors (1).
The control unit (3) then actuates the light deflection device corresponding to the headlamp being exposed to the light from the oncoming vehicle B to deflect light from the corresponding headlamp unit (201). For example, the control unit (3) may actuate light deflection device corresponding to headlamp unit (201) on right side of the vehicle (200) when light from the oncoming vehicle B reaches the sensors (1) on right side of the vehicle (200) as can be seen in Figure 4b.
In an embodiment, the light deflection device (2) automatically deflects light on to the oncoming vehicle to avoid blinding of drivers without reduction in illumination of path.
In an embodiment, the light deflection device (2) may be retrofit to headlamp units of existing vehicles at a low-cost.
In an embodiment, the control unit (3) individually operates the light deflection device (2) of each headlamp unit (201) for maximal illumination of the path in front of the vehicle (200).
