DESC:TECHNICAL FIELD
[0001] The present subject matter relates generally to a vehicle, and more particularly but not exclusively relates to a headlamp assembly.
BACKGROUND
[0002] Conventionally, vehicles such as motorcycles, scooters, trike, autorickshaws etc., include a cowl assembly supported by a head tube. The cowl assembly of a conventional vehicle houses at least a portion of a handlebar member, a front position lamp unit, a pair of front turn signal lamps, and a headlamp assembly.
[0003] Conventionally, the headlamp assembly is electrically operated, usually round in shape, consisting of parabolic reflecting surface, and is disposed on a front portion of the vehicle. The headlamp assembly to illuminate the road ahead of the vehicle, when vehicle is in moving state, by using a distributed beam of light. The light is projected, and the beam is focused on the road, by means of simple symmetric round reflecting surface.
[0004] Usually, the headlamp assembly is required to produce a low and a high beam, which may be produced by multiple pairs of single-beam lamps or by a pair of dual-beam lamps, or a mix of single-beam and dual-beam lamps. The high beam cast most of its light straight ahead, maximizing distance of vision but causes hindrance to the oncoming vehicle. Because there is no special control of upward light, the high beam also causes back dazzle from fog, rain and snow due to the retro reflection of the water droplets. On the other hand, low beam has more control of the upward light, and direct most of its light downward and either rightward (in right-traffic countries) or leftward (in left-traffic countries), to provide better forward visibility without excessive glare or back dazzle.

DETAILED DESCRIPTION
[00010] Over the years headlamp designs have evolved to become a key part of vehicle styling. Headlamps being prominently visible from a front of the vehicle have acquired signature designs that allow the vehicle to be distinguished from vehicles of competing brands. Conventionally, headlamps made use of miniaturized halogen bulbs to illuminate the road. More recently, electric bulbs in headlamps are being replaced by one or more Light Emitting Diodes (LEDs).
[00011] Light-emitting diodes are being preferred due to their smaller construction, better efficiency, higher light output, and longevity as compared to halogen bulbs. Light-emitting diodes have contributed significantly to achieve high light output. Headlamps employ reflectors to focus light emitted by the halogen bulbs/ light-emitting diodes on to road. Reflectors efefctuate efficient distribution of the light. The reflectors are disposed inside the headlamp housing. Conventional reflectors have a high beam reflector and a low beam reflector disposed in a stepped manner and integrated into one reflector unit and placed in a compartment of the headlamp assembly. The integrated arrangement of the reflector unit requires more area to ensure that light emitted has adequate throw and focus. Thus, the reflector unit becomes bulky and would require a bigger headlamp assembly to house it. It increases complexity of assembly and reduces design flexibility.
[00012] Some known arts suggest reducing the overall size of the headlamp assembly to achieve compactness. However, such reduction in size often leads to either reduced light output or reduced light distribution, thereby reducing the road visibility. Further such reduction in size complicates the structure of the headlamp assembly and negatively impact the thermal management of the headlamp assembly.
[00013] Thereby, it is desired to have a head lamp assembly which is compact in size, has design flexibility with good thermal management.
[00014] Furthermore, in some known arts, front positioning lamps (FPLs) are not accommodated in a headlamp compartment due to thermal constraints. A larger headlamp compartment would be required to accommodate the front positioning lamps within the headlamp compartment since it would be difficult to manage heat buildup in the headlamp assembly without increasing its size. It is not desirable to increase size of the headlamp assembly due to vehicle layout constraints and costs involved. A large headlamp assembly also protrudes outwardly towards front of the vehicle, increasing the front overhang mass. In two wheelers this causes the headlamp assembly to overhang from the front forks and away from center of gravity of the vehicle. This detrimentally affects the vehicle’s handling. Therefore, it is desirable to have a compact headlamp assembly disposed as close to the front forks as possible to improve vehicle handling.
[00015] Some other known arts disclose light-emitting diode collimator element for a low beam function of the headlamp by using projector-based technology instead of using reflector-based technology to achieve non uniform brightness distribution. However, the overall construction of the headlamp assembly with both high beam and low beam function, using the projector-based technology is not known. Further, it also becomes challenging to control the color transgressions when projector-based technology is used. Herein, color transgression signifies the breakdown of white light into different wavelengths of different colors. It is desired to use the projector-based technology within the headlamp assembly with a controlled color transgression. Hence, there is a need to have a compact head lamp assembly which can accommodate front positioning lamps without thermal constraints.
[00016] Hence, there is a need of a compact headlamp assembly disposed as close to the front forks as possible to improve vehicle handling, accommodate front positioning lamps without thermal constraints while enabling controlled color transgression. The present subject matter has been devised in view of the above circumstances.
[00017] The present subject matter discloses a headlamp assembly.
[00018] As per an aspect, the present subject matter aims to achieve a light weight, compact light-emitting diodes headlamp assembly by disposing internal components like collimator, lens, multiple light-emitting diodes in such a manner that provides better packaging of the components in a compact space is achieved.
[00019] The present headlamp assembly includes a modular design with three modules separately performing the functions of a high beam, a low beam, and a front position lamp. Herein the high beam, the low beam, and the front position lamp are housed together within an integrated housing. Further the integrated housing along with the high beam, the low beam, and the front position lamp are covered by an outer lens. As per an embodiment, the lens is placed in an inclined manner over the integrated housing.
[00020] Further, as per another embodiment, a bezel is placed in between the lens and the housing. The bezel aids in holding the plurality of components placed within the integrated housing in position. The bezel also aids in hiding the inner details and wiring details of the headlamp assembly.
[00021] The rear portion of the housing, i.e. the portion of the housing facing towards the front cover, includes one or more headlamp mounting provisions. The one or more headlamp mounting provisions aid in mounting of the headlamp assembly.
[00022] In another embodiment, the one or more headlamp mounting provisions aid in mounting of the headlamp assembly in front of the handlebar assembly of the vehicle.
[00023] The mounting provisions provide improved convenience and ease of installation.
[00024] The headlamp assembly in accordance with the present embodiment, uses a plurality of light-emitting diodes as the light source. The plurality of light-emitting diodes is integrated with the at least one printed circuit board. Further at least one collimator are mounted onto the at least one printed circuit board.
[00025] The collimator narrows the beam of light emitted by the light-emitting diodes and direct the light as parallel beams in a specific direction. Thereby, once the light waves are emitted by the light-emitting diodes, the collimator receives the light and focuses the light aligned in parallel to the at least one inner lens surface.
[00026] Herein as an embodiment, the at least one collimator includes a front position lamp (FPL) collimator, a low beam collimator, and a high beam collimator.
[00027] Further, the at least two inner lens is disposed after the collimator. The at least one inner lens receives the directed light and further redistributes the light towards the outer lens in a scattered manner. Further the outer lens distributes the light on the road to achieve the desired optical distribution requirements. Herein the at least one inner lens includes a front position lamp lens, a low beam lens, and a high beam lens.
[00028] The above stated embodiment describes a specific construction of inner lens that are disposed after the collimator to receive the directed light and scatter it towards the outer lens in a desired manner to achieve desired optical distribution requirements. This configuration allows for precise beam shaping and control, which may provide improved illumination performance compared to prior art headlamp designs.
[00029] As per an embodiment, each of the low beam lens, and the high beam lens are compartmentalized into more than one compartments. The compartmentalization of the each of the low beam lens, and the high beam lens aid in achieving desired distribution of light efficiently within a compact headlamp assembly setup. This configuration allows for further refinement of the beam control and light distribution, which may also provide improved illumination performance.
[00030] Herein the at least one printed circuit board along the light-emitting diodes is directly mounted onto the at least one heat sink. Herein the at least one heat sink used is a passive heat exchanger that transfers the heat generated by the at least one printed circuit board along the light-emitting diodes to a fluid medium, often air or a liquid coolant where it is dissipated away from the at least one printed circuit board along the light-emitting diodes, thereby enabling thermal management of the headlamp assembly. Further, the at least one heat sink herein used has maximum thermal performance while minimum weight.
[00031] Further, in an embodiment the at least one printed circuit board includes a front position lamp printed circuit board, a low beam printed circuit board, and a high beam printed circuit board.
[00032] As per an embodiment, the front position lamp printed circuit board, the low beam printed circuit board, and the high beam printed circuit board are placed together in a stepped manner, such that the high beam lens along with the high beam printed circuit board is placed forwardly of the low beam lens along with the low beam printed circuit board. The forward placement of the high beam lens along with the high beam printed circuit board ensures proximity of the high beam lens with the outer lens. Such proximity of the high beam lens along with the high beam printed circuit board with the outer lens ensures desired light output from the high beam module. Accordingly, to accommodate the stepped printed circuit board the heat sink and the housing is also designed in stepped manner.
[00033] As per an embodiment, the front position lamp lens includes multiple stepped structured pattern which further gives a sparkling effect, when the light exists the front position lamp lens.
[00034] The stepped arrangement of printed circuit board provides better thermal management by allowing the heat generated by the high beam printed circuit board to be dissipated more efficiently.
[00035] As per an aspect of the present subject matter, the present subject matter ensures vertical compactness along with horizontal compactness of the headlamp assembly, due to stepped profile of the printed circuit board along with the heat sink and the housing.
[00036] As per another embodiment, the stepped structure of the housing aid in packaging wiring and components such as couplers in at least one of the stepped portions.
[00037] As per another aspect of the present subject matter, the present subject matter ensures safe, aesthetically appealing, durable, and easy to manufacture the headlamp assembly.
[00038] As per another aspect of the present subject matter, the present subject matter ensures ease in service, and ease in assembly of the headlamp assembly, thereby ensuring ease in comfort.
[00039] Further, as per another aspect of the present subject matter, the present subject matter ensures significantly reduced part count and reduced weight of the proposed headlamp assembly.
[00040] As per another embodiment, the present headlamp assembly is modular in nature, i.e. the position of the front position lamp module, the low beam module and the high beam module can be swapped depending upon the desired light output requirement, and the placement and positioning of the headlamp assembly. Thereby several combinations of the front position lamp module, the low beam module and the high beam module can be formed, giving design flexibility to the headlamp assembly.
[00041] Although, use of light-emitting diode collimator element for a low beam function of the headlamp by using projector-based technology instead of using reflector-based technology to achieve non uniform brightness distribution is known in prior art. The overall construction of the headlamp assembly with both high beam and low beam function, using the projector-based technology is not known. The above stated embodiments of the current application describe a specific arrangement of inner lens that are disposed after the collimator to receive the directed light and scatter it towards the outer lens in a desired manner to achieve desired optical distribution requirements. This configuration, configuration allows for precise beam shaping and control, which may provide improved illumination performance compared to prior art headlamp designs. Further, this configuration allows several combinations of the front position lamp module, the low beam module, and the high beam module to be employed as per the requirements of application, giving design flexibility to the headlamp assembly.

Different parts of the step through-type vehicle 100 are supported by a frame structure (not shown). The frame structure supports a steering assembly including a steering shaft (not shown), and a handlebar assembly 105 in a front portion of the step through-type vehicle 100. A front fork 121 is rotatably supported to the steering shaft through an upper bracket (not shown) and a lower bracket (not shown). The handlebar assembly 105 provided above the front fork 121 allows steering of a front wheel 125.
[00045] Further, a front cover 115 is provided to cover a forward-facing side of the frame structure. In an embodiment a headlamp assembly 110 is disposed in front of the handlebar assembly 105. In another embodiment, the headlamp assembly 110 is disposed upon the front cover 115.
[00046] A front fender 120 is provided to cover an upper portion of the front wheel 125. A leg shield 130 protects the rider’s legs rested on a floorboard 145 from running wind. An under-seat cover 140 is provided that extends upwards from a floorboard 145 towards a lower side of a seat 135.
[00047] In one embodiment, the under-seat cover 140 serves to protect an Internal Combustion (IC) engine 102 disposed under the seat 135. The seat 135 is disposed above the left and right side covers 175. A pillion-handle 165 extending rearwardly behind the seat 135 is provided as a gripping means for a pillion rider seated on the seat 135.
[00048] For safety of the rider and in conformance with the traffic rules, the headlamp assembly 110 and a turn signal lamp unit 111 are provided in a front portion of the step-through vehicle 100, and tail lamp unit 170 is provided in a rear portion of the step-through vehicle 100. Safety of the step through-type vehicle 100 is also improved by providing a braking system, for example a linked type braking system which controls braking operation of a front brake device (not shown) and a rear brake device (not shown) of the front wheel 125 and the rear wheel 190 respectively. The braking system includes a front brake lever 132 and a rear brake lever (not shown) to be operated by the rider and connected to said front brake device and the rear brake device respectively through one or more cables including a front brake cable (not shown) and a rear brake cable (not shown).
[00049] For comfortable riding, suspension systems are provided for comfortable steering of the vehicle 100 on the road. The front fork 121, which forms the front suspension system, serves as rigidity component. The front fork 121 clamped to the head tube (not shown) through an upper bracket (not shown) and a lower bracket (not shown) is capable of being moved/steered to the left and right. Further, at least one rear suspension (not shown), which is a hydraulic damped arrangement, is connected to the frame structure at a rear portion thereof. Particularly, at the rear portion of the frame structure, the rear wheel 190 is suspended by the rear suspension.
[00050] To enhance the overall aesthetics of the vehicle 100 and to prevent undesired foreign particles from entering parts of the vehicle 100, left and right side covers 175 are disposed to cover left and right-side surfaces of a rear portion of the frame structure. A rear fender 180 is also provided for preventing mud/water splashed by the rear wheel 190 from entering other parts of the vehicle 100.
[00051] The step through-type vehicle 100 is designed to be powered by the IC engine 102 that is equipped with an exhaust system that includes an exhaust pipe (not shown) connected to the IC engine 102 and a muffler 185 connected to the exhaust pipe. The muffler 185 extends rearwards along the right side of the rear wheel 190. Power from the IC engine 102 is transmitted to the rear wheel 190 through a transmission assembly (not shown), to drive and rotate the rear wheel 190. The transmission assembly includes a gear unit containing gear train and a drive mechanism connecting the gear unit to the rear wheel 190. Thus, power from the IC engine 102 is transmitted to the rear wheel 190.
[00052] Figure 2 illustrates a headlamp assembly 110 of a vehicle 100 in accordance with an embodiment of the present subject matter. The present headlamp assembly 110 follows a modular design with three modules separately performing the functions of a high beam, a low beam, and a front position lamp. Herein the high beam, the low beam, and the front position lamp are housed together within a housing 202. Further the housing 202 along with the high beam, the low beam, and the front position lamp are covered by an outer lens 201. As per an embodiment, the outer lens 201 is placed in an inclined manner over the housing 202. Inclined lens enables the light to be directed more accurately towards the road surface, preventing scattering of the light in undesired direction and reduce glare for oncoming drivers.
[00053] Further, as per another embodiment, a bezel (not shown) is placed in between the lens 201 and the housing 202. The bezel aids in holding the plurality of components placed within the housing 202 in position. The bezel also aids in hiding the inner details and wiring details of the headlamp assembly 110.
[00054] The rear portion of the housing 202, i.e. the portion of the housing 202 facing towards the front cover 115 (shown in Figure 1), includes one or more headlamp mounting provisions 200. The one or more headlamp mounting provisions 200 aid in mounting of the headlamp assembly 110.
[00055] In another embodiment, the one or more headlamp mounting provisions 200 aid in mounting of the headlamp assembly 110 in front of the handlebar assembly 105 (shown in Figure 1) of the vehicle 100.
[00056] The one pr more headlamp mounting provisions 200 provide improved convenience and ease of installation.
[00057] Figure 3 illustrates an exploded view of the headlamp assembly 110 of a vehicle 100 in accordance with an embodiment of the present subject matter. Figure 4 illustrates a sectional view of the headlamp assembly 110 of a vehicle 100 in accordance with an embodiment of the present subject matter. The exploded view as depicted by Figure 3 shows the housing 202 housing a plurality of components. The plurality of components includes at least one heat sink 206, at least one Printed Circuit Board (PCB) 206, at least one collimator 204, at least one inner lens 203a, 203b, 203c, and the outer lens 201. In an alternate embodiment, the headlamp assembly 110 includes a bezel (not shown).
[00058] The headlamp assembly 110 in accordance with the present embodiment, uses a plurality of light-emitting diodes 210 as the light source. The plurality of light-emitting diodes 210 are integrated with the at least one printed circuit board 205. Further the at least one collimator 204 are mounted onto the at least one printed circuit board 205.
[00059] Herein, the collimator 204 is a device which narrows the beam of light emitted by the light-emitting diodes 210 and direct the light as parallel beams in a specific direction. Thereby, once the light waves are emitted by the light-emitting diodes 210, the collimator 204 receives the light and focuses the parallelly aligned light on the at least one inner lens 203a, 203b, 203c surface.
[00060] Herein as an embodiment, (as shown in Figure 4) the at least one collimator 204 includes a front position lamp (FPL) collimator 204a, a low beam collimator 204b, and a high beam collimator 204c.
[00061] Further, the at least one inner lens 203a, 203b, 203c is disposed between the at least one collimator 204 and the outer lens 201. The at least one inner lens 203a, 203b, 203c receives the directed light and further redistributes the light towards the outer lens 201 in a scattered manner. Further the outer lens 201 distributes the light on the road to achieve the desired optical distribution requirements. Herein the at least one inner lens 203a, 203b, 203c (as shown in Figure 4) includes a front position lamp (FPL) lens 203a, a low beam lens 203b, and a high beam lens 203c.
[00062] The above stated embodiment describes a specific arrangement of inner lens 203a, 203b, 203c that are disposed after the collimator 204 to receive the directed light and scatter it towards the outer lens 201 in a desired manner to achieve desired optical distribution requirements. The inner lens allows uniform distribution of light by scattering the light rays in different direction while reducing hot spots or dark areas. This allows for precise beam shaping and control, which may provide improved illumination performance compared to prior art headlamp designs.
[00063] As per an embodiment, each of the low beam lens 203b, and the high beam lens 203c are compartmentalized into more than one compartments. The compartmentalization of the each of the low beam lens 203b, and the high beam lens 203c aid in achieving desired distribution of light efficiently within a compact headlamp assembly 110 setup. This configuration allows for further refinement of the beam control and light distribution, which may also provide improved illumination performance.
[00064] Herein the at least one printed circuit board 205 along the light-emitting diodes 210 is directly mounted onto the at least one heat sink 206. Herein the at least one heat sink 206 used is a passive heat exchanger that transfers the heat generated by the at least one printed circuit board 205 along the light-emitting diodes 210 to a fluid medium, often air or a liquid coolant where it is dissipated away from the at least one printed circuit board 205 along the light-emitting diodes 210, thereby enabling thermal management of the headlamp assembly 110. Further, the at least one heat sink 206 herein used has maximum thermal performance while minimum weight. Since the heat sink 206 is designed to be in direct contact with the printed circuit board 205 and the light-emitting diodes 210, the heat generated by these components is dissipated directly by the heat sink 206 without affecting the other components. This ensures that the lenses 203 are not affected by the heat generated by the printed circuit board 205 and the light-emitting diodes 210, thereby maintaining the optical performance of the headlamp assembly 110.
[00065] Further, in an embodiment (as shown in Figure 4) the at least one printed circuit board 205 includes a front position lamp printed circuit board 205a, a low beam printed circuit board 205b, and a high beam printed circuit board 205c.
[00066] As per an embodiment, the front position lamp printed circuit board 205a, the low beam printed circuit board 205b, and the high beam printed circuit board 205c are placed together in a stepped manner, such that the high beam lens 203c along with the high beam printed circuit board 205c is placed forwardly of the low beam lens 203b along with the low beam printed circuit board 205b. The forward placement of the high beam lens 203c along with the high beam printed circuit board 205c ensures proximity of the high beam lens 203c with the outer lens 201. Such proximity of the high beam lens 203c along with the high beam printed circuit board 205c with the outer lens 201 ensures desired light output from the high beam module. Accordingly, to accommodate the stepped printed circuit board 205 the heat sink 206 and the housing 201 is also designed in stepped manner.
[00067] As per an embodiment, the front position lamp lens 203a includes multiple stepped structured patterns. The stepped pattern can cause the light to be refracted at different angles, creating a scattering effect that produces a sparkling or glittering appearance when the light exits the front position lamp lens 203a, thus improving the visibility of the vehicle 100 and increases its safety on the road. Further, by refracting the light in different directions, the stepped structured pattern can help to distribute the light more evenly across the surface of the front position lamp lens 203a, reducing the formation of hotspots or dark areas. This can improve the overall illumination of the headlamp assembly 110, making it more effective at illuminating the road ahead.
[00068] The stepped arrangement of printed circuit board provides better thermal management by allowing the heat generated by the high beam printed circuit board 205c to be dissipated more efficiently. The stepped arrangement allows for better air flow around the high beam printed circuit board 205c and prevents accumulation of hot air around the high beam printed circuit board 205c.
[00069] As per an aspect of the present subject matter, the present subject matter ensures vertical compactness along with horizontal compactness of the headlamp assembly 110, due to stepped profile of the printed circuit board 205 along with the heat sink 206 and the housing 202.
[00070] As per another aspect, the stepped structure of the heat sink 206 allows the heat sink 206 to be attached directly to the printed circuit board 205 improving the efficiency of heat dissipation.
[00071] As per another aspect, the stepped structure of the housing 202 aid in packaging wiring and components such as couplers in at least one of the stepped portions. Further, the stepped structure of the housing 202 aid in providing a compact structure to the headlamp assembly 110.
[00072] As per another aspect of the present subject matter, the present subject matter ensures safe, aesthetically appealing, durable, and easy to manufacture the headlamp assembly 110.
[00073] As per another aspect of the present subject matter, the present subject matter ensures ease in service, and ease in assembly of the headlamp assembly 110, thereby ensuring ease in comfort.
[00074] Further, as per another aspect of the present subject matter, the present subject matter ensures significantly reduced part count and reduced weight of the proposed headlamp assembly 110.
[00075] As per another embodiment, the present headlamp assembly 110 is modular in nature, i.e. the position of the front position lamp module, the low beam module and the high beam module can be swapped depending upon the desired light output requirement, and the placement and positioning of the headlamp assembly 110. Thereby several combinations of the front position lamp module, the low beam module and the high beam module can be formed, giving design flexibility to the headlamp assembly 110.
[00076] As per an embodiment, a plurality of collimator 204 can be employed, wherein at least one of the plurality of collimator 204 is configured distinctly from other. Using plurality of collimator 204 with distinct configurations eliminates the need for additional components such as reflectors. As, collimators are typically designed to be more compact than traditional reflectors, use of plurality of collimator 204 can help minimize the overall depth of the headlamp assembly 110. Thus, the use of plurality of collimator 204 can allow the headlamp assembly 110 to be designed with a shallower and compact profile. The use of plurality of collimators 204 with distinct configurations can provide benefits in terms of space consideration and compactness, which can be particularly useful in applications where space is limited or where a more aesthetically pleasing design is desired. Further, the use of plurality of collimators 204 can also help to improve the overall aesthetic appearance of the headlamp assembly.
[00077] Many modifications and variations of the present subject matter are possible in the light of above disclosure. Therefore, within the scope of claims of the present subject matter, the present disclosure may be practiced other than as specifically described.
