CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application claims priority from Indian Provisional Patent Application No. 202121039801 dated September 2, 2021.
TECHNICAL FIELD
The present disclosure in general relates to a headlamp assembly in automobiles, and more particularly to a Bi-function projector module having multiple light distribution patterns and internal levelling setup.
BACKGROUND
The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
A vehicle includes an external lighting assembly for illuminating an area ahead of the vehicle. The External Lighting assembly essentially comprises a headlamp, wherein the headlamp consists of two distinct light distribution patterns i.e., Low beam and High beam. The Low beam allows the driver to manoeuvre the vehicle in the city without glaring the oncoming drivers or pedestrian. The Low beam comprises of a horizontal cut-off line and the light distribution is formed below this cut-off resulting with a reduced glare. The High Beam, which has more range thereby improving the far range visibility, assists in driving the vehicle in highways.

To achieve functioning of both high-beam and low-beam features, the headlamp comprises a bi-function projector module. In the existing art, the bi-function projector module comprises a dynamic shade, wherein the dynamic shade is operated using a solenoid to switch between high beam and low beam to form a cut-off line. However, the dynamic shade partially absorbs light rays, which eventually reduces efficiency of the headlamps. Further, some bi-functional projector module employs static shades to form a cut-off line, however, the static shades also partially absorbs light rays, which eventually reduces efficiency of the headlamps.
Also, in the conventional bi-function projector modules, during laden and unladen conditions of the headlamp, the low beam cut-off moves up or down, which results in glare or inadequate light on road. As a result, the cut-off line must be adjusted vertically by levelling, which can be done manually or automatically. In conventional projector modules, internal levelling is not possible, and module must be coupled with levelling components which are enclosed in a housing to allow vertical levelling. This results in much more components and bulkier headlamps.
Therefore, there is an utmost need for a headlamp comprising a member provisioned with less light absorbing properties, and an internal levelling means to form a proper low beam cut-off line.
SUMMARY
This summary is provided to introduce concepts related to a Bi-function projector module having multiple light distribution pattern and internal levelling setup. This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in determining or limiting the scope of the claimed subject matter.
In an embodiment of the present disclosure, a bi-functional projector module for an automobile is described. The bi-functional projector module comprises a

The present subject matter relates to a bi-functional projector module for an automobile with an internal levelling module (hereinafter also referred to as Bi-functional Projector). Further, the bi-functional projector may be implemented in a vehicle, such as two-wheeler, three-wheeler, or four-wheeler vehicles such as, but not limited to, motorcycle, scooters, cars, and the like.
In one implementation, the present subject matter describes a bi-function projector module having multiple light distribution patterns and an internal levelling

module setup. Further, the Bi-function projector may comprise a first lens system, a second lens system, a projector lens, a first light source, a second light source, a printed circuit board, a pivot point, a heat dissipation means, and a mirror.
In one embodiment, the first light source and the second light source may be mounted/positioned on the printed circuit board, wherein the printed circuit board may be further equipped with the heat dissipation means. Further, the first lens system may be equipped with the first light source, and the second lens system may be equipped with the second light source. Further, the first light source is configured to provide a first light distribution as a low beam light distribution pattern, and in combination with a second light distribution from the second light source, a high beam light distribution is achieved.
In one embodiment, the Bi-function projector module may be equipped with an internal levelling module/means, wherein the internal levelling module/means may be envisaged using a predetermined pivot point and a levelling axis. Further, the internal levelling module may include a mechanism to rotate the printed circuit board, which further rotates the assembly of the first lens system, the second lens system, the first light source, the second light source mounted over the printed circuit board about a levelling axis while keeping the projector lens static. Further, the internal levelling module may enable adjusting the cut-off line of the low beam light distribution to prevent glare or inadequate light on the road.
In one embodiment, the Bi-function projector module may be equipped with a mirror surface, wherein the mirror surface comprises a metallized component, wherein the mirror surface is configured to provide a definite cut-off line as in first lighting condition (e.g., low beam), by reflecting the partial rays falling over it from the first lens system and guiding it to the projection lens.
Now, referring to Figure 1, an isometric view 100 of the bi-functional projector 102 is illustrated, in accordance with an embodiment of the present subject matter. Further, the bi-functional projector 102 may be configured to operate in/provide a

first lighting condition and a second lighting condition in an automobile/vehicle, wherein the first lighting condition may form a low beam light distribution and the second lighting condition may form a high beam light distribution, wherein the low beam distribution or the high beam light distribution may be selectively operated by the driver. The bi-functional projector 102 may be deployed in a vehicle to perform various illuminating functions, such as, but not limited to, illuminating a road ahead of the automobile/vehicle. For example, the bi-functional projector 102 may be implemented in a vehicle, such as two-wheeler, three-wheeler, or four-wheeler vehicles such as, but not limited to, motorcycle, scooters, cars, and the like.
Now, referring to Figure 2, a side view 200 of the bi-functional projector 102 is illustrated, in accordance with an embodiment of the present subject matter. Further, the bi-functional projector 102 may comprise a first lens system 202, a second lens system 204, a projector lens 214, at least one first light source 212, at least one second light source 208, a printed circuit board 206 (also referred to as printed circuit board assembly 206), a pivot point 210, a heat dissipation means (not shown in figure), and a mirror 216. The first lens system 202 and second lens system 204 may also have been referred hereinafter as first lens 202 and second lens 204. In one embodiment, the first light source 212 and the second light source 208 may be positioned/mounted on the printed circuit board 206, wherein the printed circuit board 206 may be further equipped with the heat dissipation means and the pivot point 210. The first light source 212 and the second light source 208 mounted on the PCB assembly 206 may together be referred to as a lighting module 218. Further, the first lens system 202 may be equipped with the at least one first light source 212, and the second lens system 204 may be equipped with the at least one second light source 208, which assists in the thermal management in the bi-functional projector module 102. Further, the first light source 212 and the second light source 208 may be movable about the pivot point 210, to adjust the position of horizontal cut-off lines of the first light distribution. The first light

distribution pattern is associated with a light distribution at the automobile below a horizontal cut-off line.
In one embodiment, the first lens system 202, the second lens system 204, the first light source 212, the second light source 208 are mounted on the PCB 206 to form a single assembly, also referred hereinafter as PCB assembly 206. An internal levelling module or aiming element/system (not shown in Fig. 2) may be coupled to a board of the PCB assembly 206 or the first collimator /first lens system 202, which facilitates rotational movement of the PCB assembly across the pivot point 210.
In one embodiment, the first light source 212 may be configured to provide a first light distribution as a low beam light distribution pattern. Further, to achieve a high beam distribution, the first light distribution may be achieved in combination with a second light distribution.
In an embodiment, the PCB assembly 206 may be arranged at a tilt angle with respect to an axis of light from the bi-functional projector 102, i.e., the x-axis (not shown). In an exemplary embodiment, the tilt angle may be in a range of 15 degrees to 20 degrees. In one non-limiting embodiment, the tilt angle may be around 17 degrees from the axis of light (i.e., x-axis). The tilt angle in combination with the rotation of the PCB assembly 206 facilitates an improved viewing angle of the light distributed in front of the vehicle/automobile.
In one embodiment, the bi-functional projector 102 may comprise a mirror 216. Now, referring to Figure 3, a top view 300 of the bi-functional projector 102 is depicted. Therefore, it can be seen that the mirror 216 may be positioned above the second lens system 204, wherein one edge of the mirror 216 may lie at a focal point of the projector lens 214. Further, the mirror 216 may comprise a metallized component, wherein the metallized component may be configured to reflect light rays from the light sources to provide a cut-off line in the first lighting condition, i.e. low beam light condition. Further, the mirror reflects the light rays from the

first light lens system 202, towards the projector lens 214, eliminating the problem of partial absorption of light rays.
In one embodiment, referring to Figure 4, a first lighting condition 400 of the bi-functional projector 102 is illustrated. Further, the first lighting condition may comprise a first light distribution, wherein the first light distribution may comprise a low beam light distribution. As can be seen from Figure 4, only the first light source 212 may be operated. Further, the light rays from the first light source 212 may enter the first lens system 202. Further, the light rays may be redirected towards the mirror 216 using internal properties of the mirror 216. Further, the mirror 216 may be configured to reflect the light rays towards the projector lens 214. Further, the light rays exit the projector lens 214 as a low beam light distribution.
In one embodiment, referring to Figure 5, a light distribution of the first lighting condition is illustrated. Further, it may be seen that light rays may be distributed in a lower space of the light distribution, thereby forming a low-beam light distribution for low beam pattern. Low beam is used for normal night-time driving and is also known as dipped beam. As can be seen, the projection pattern is in lateral and downward fashion, and it provides adequate lighting on the road in near field without distracting the oncoming traffic with glare.
In one embodiment, referring to Figure 6, light distribution 600 from the second light source of the bi-function projector module 102 is depicted. It can be seen that only the second light source 208 may be operated. Further, the light rays from the second light source 208 may enter the second lens system 204. Further, the light rays may be redirected towards an edge of the mirror 216, which may be the focal point of the projector lens 214. Further, the edge of the mirror 216 may be configured to deflect the light rays towards the projector lamp 214. Further, the light rays exit the projector lens 214 as a second light distribution.

In one embodiment, referring to Figure 7, which illustrates light distribution 700 from the second light source 204. Further, it may be seen that light rays may be concentrated at an upper space of the region. Figure 7 illustrates the high beam portion of the overall pattern. The high beam is generally used on highways or when driving in very high speed. The light distribution is more centralised, and it allows the driver/passenger to see the longer range on the road.
In one embodiment, referring to Figure 8, a second lighting condition 800 of the bi-functional projector is illustrated. Further, the second lighting condition may comprise a combination of the first light distribution from the first light source 212, and the second light distribution from the second light source 208 to form a high beam distribution. Referring to Figure 8, it can be seen that the first light source 212 and the second light source 208 may both be operated. Further, the light rays from the first light source 212 may enter the first lens system 202. Further, the light rays from the first light source 212 may be redirected towards the mirror 216. Further, the light rays from the second light source 208 may enter the second lens system 204. Further, the light rays from the second light source 208 may be redirected towards an edge of the mirror 216. Further, the mirror 216 may be configured to reflect the light rays from the first light source towards the projector lens 214, and the edge of the mirror 216 may be configured to deflect the light rays towards the projector lens 214. Further, the light rays exit the projector lens 214 as a cumulative light distribution or a high beam light distribution.
In one embodiment, referring to Figure 9, a light distribution 900 of the second lighting condition is depicted. Further, it may be seen that light rays may be distributed in a lower space as well as a higher space of the light distribution, thereby forming a high-beam light distribution. As can be appreciated and realized that the recent projector lamps are built in such a way the high beam function is activated together with the low beam. This allows to visualise the centralised illuminance on the road for longer stretch without losing the light in the near field. The projector is also built in a such a say, that the low beam function will remain

ON during the high beam operation and provide the visibility for the near field also during this mode. This is possible only by having separate light sources for low beam and high beam.
Now, referring to Figure 10, a working of the internal levelling module for cut-off adjustment of the bi-function projector module 102 is illustrated, in accordance with an embodiment of the present subject matter. Further, the bi-function projector module 102 may be equipped with an internal levelling means, wherein the internal levelling means may be envisaged using the pivot point 210 and a levelling axis (depicted in Figs. 10 and 11 along the PCB assembly 206). Further, the internal levelling may be achieved by rotating the printed circuit board 206 about the pivot point 210. Specifically, the internal levelling module may be configured to rotate the printed circuit board assembly for vertically adjusting the horizontal cut-off line associated with the first light distribution pattern. Further, the PCB assembly of the first lens system 202, the second lens system 204, the first light source 212, the second light source 208 mounted over the printed circuit board 206 may be rotated while keeping the projector lens 214 static. Further, such arrangement helps in meeting the lighting regulation and necessary light pattern in different driving re-aim conditions up to ± 3 degree. Therefore, such levelling mechanism may enable adjusting the cut-off line of the low beam light distribution to prevent glare or inadequate light on the road. It must be noted herein that the optical parts for the low beam and high beam and the printed circuit board assembly are connected mechanically on an additional part as bezel (not shown). This additional part is further attached to an aiming element, which is a part of the internal levelling module. The aiming element may be manually adjusted from outside or there can be one internal/external motor to facilitate the desired rotation.
Referring to Figure 11, an isometric view of internal levelling module/aiming element 1102 for rotating the printed circuit board assembly is illustrated. The internal levelling module/aiming element 1102 comprises an element 1104 which may be manually adjusted from outside or there can be one internal/external

motor to facilitate the desired rotation of the PCB assembly. The rotation of the PCB assembly via the internal levelling module 1102 may be performed via the pivot point 210. The element 1104 may be configured to facilitate rotation of the PCB assembly via an inward/outward movement of the element 1104, wherein the element may be adjusted either manually or via a motor. Corresponding to the inward/outward movement of the element 1104, the PCB assembly may be rotated in upward/downward direction as indicated via dotted lines in the Fig. 11. In an embodiment, the element 1104 may be coupled to a lever or switch or a mechanical apparatus to facilitate the movement of the internal levelling module 1102 or the PCB assembly. This is explained in conjunction with Figure 12 in detail.
Referring to Fig. 12, an exploded view of the internal levelling module/aiming element 1102 is provided. As depicted, the internal leveling module 1102 comprises two mounting pivots 1202a and 1202b attached to the bi-function projector module 102. The mounting pivots 1202a-1202b may be used to couple the internal levelling module 1102 with the PCB assembly of the bi-function projector module 102. The internal levelling module 1102 may include the mounting pivots 1202a-1202b, holding element or mounting brackets 1204a-1204b for holding the PCB assembly, and the levelling screw 1206. The levelling screw 1206 is configured to facilitate rotation of the PCB assembly. In an embodiment, the inward and outward movement of the levelling screw 1206 facilitates swivel of the internal levelling module 1102, thereby rotating the PCB assembly of bi-function projector module 102. However, the internal levelling module 1102 is not limited to above example and any other internal levelling mechanism that can facilitate the rotation of the internal assembly is well within the scope of present disclosure.
The aforementioned illustrated embodiments offer the following advantages over the conventional Bi-functional Projector, which include but are not limited to:

• A Compact Bi-functional Projector, as the need for external means for levelling is eliminated.
• The Compact Bi-functional Projector configured to maximum reflection of the light rays from the light sources, with minimal absorption.
• The bi-functional projector is configured to improve light efficiency for the vehicles by facilitating movement of the PCB assembly. The movement controls a viewing area in front of the projector or headlamp while also providing an aesthetic compact assembly of the bi-functional projector. In contrast, the prior art solutions provide movement of such bi-functional projector “externally” which leads to an unpleasant visible gap between the projector lamp and other part (e.g., bezel) of the automobile.
• Further, the bi-functional projector of the present disclosure provides a wide-light distribution of the light sources which facilitates better visibility for the driver. Additionally, the multiple light sources may be implemented which improve thermal stability.
• Finally, the horizontal width of the bi-functional projector is also improved over conventional solutions due to modification of cut-off lines via the rotation of PCB assembly. This leads to dynamic adjustment of the light distribution in front of the automobile.
Various modifications to the embodiments will be readily apparent to those skilled in the art and the generic principles herein may be applied to other embodiments. However, one of ordinary skill in the art will readily recognize that the present disclosure is not intended to be limited to the embodiments illustrated but is to be accorded the widest scope consistent with the principles and features described herein.
The foregoing description shall be interpreted as illustrative and not in any limiting sense. A person of ordinary skill in the art would understand that certain modifications could come within the scope of this disclosure.

The embodiments, examples and alternatives of the preceding paragraphs or the description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
