DETAILED DESCRIPTION

[0001] Generally, a two-wheeled or a three-wheeled vehicle comprises of a frame assembly extending rearwardly from a head tube. The frame assembly acts as a skeleton and a structural member for the vehicle that supports the vehicle loads. The frame structure may also comprise of a down tube extending in a downward and rearward direction from the head tube, and a main tube extending in a straight and forward direction from the head tube. At least one front wheel is connected to a front portion of the frame assembly through one or more front suspension(s). The frame assembly extends towards a rear portion of the vehicle. At least one rear wheel is connected to a frame assembly through one or more rear suspension(s). The frame assembly comprises of a head pipe disposed in a front portion of the vehicle, wherein a down tube extends from the head pipe in a downward and rearward manner. [0002] For the safety of the user and in conformance with the traffic rules, a headlight in the front portion of the vehicle and a tail light in the rear portion of the vehicle is also provided.

[0003] Generally, headlamps of vehicles are provided to illuminate the road in the darkness and help the driver of the vehicle to drive safely. Headlamps also functions to give indication to the oncoming vehicles. Vehicles typically have headlamps for increasing the motorcycle driver's visibility and/or for alerting other people to the presence of the motorcycle. In a known motorcycle type two-wheeled vehicle, a front side of a steering handle of the vehicle is covered by a front cowl in order to improve external appearance and/or to improve wind shielding effect when running. The provision of the front cowl provides for the mounting of the headlamp housing on the vehicle. Generally, headlamps are provided to illuminate the road space in front of the vehicle and it must also meet the requirements of all road users. In particular, the low beam functions are subject to various regulations and are designed to protect the oncoming traffic from being dazzled. The automotive headlamp components are in general highly controlled products. Such headlamps are available in different shapes, such as round, rectangular, trapezoidal, etc. and are placed on the body panel.

[0004] The primary components of a headlamp assembly are lens, reflector and a light source. This light source is used for illumination. Also, most of the headlamps use an incandescent bulb which uses up substantial amount of energy in the form of electrical energy which is produced by the power unit e.g. in an IC engine type vehicle it could be a magneto driven by the engine or in an electric vehicle it could be a battery source etc. Many attempts are made to reduce the consumption of energy and to improve the overall efficiency of the vehicle. One of the ways in which this can be achieved is by replacing the incandescent bulb by LEDs. This helps in achieving a reduction in the energy consumption and increase vehicle energy efficiency or mileage. However, replacing the incandescent bulb by LED poses several challenges in design of head lamp which will be discussed in detail later. Generally, in a headlamp assembly the light source is positioned at the focal point of a parabolic reflector. This is done by means of holders fixed on the casing of headlamp assembly. The reflector directs the light produced by the concentric beams coming from the source to illuminate the roads. [0005] In general, now a days the required illumination distribution on the road is the function of reflector and the clear glass lens protects the interiors of headlamp against external influences. It also constitutes the external surface of the headlamp and hence, has an important additional role in even the aesthetics & good appearance of the vehicle. The lens is a transparent or translucent surface that encloses the light source and allows the conformance with the photometric and calorimetric requirements. Lens can also be used to filter out the unwanted colors from the white colored light which is emitted by the reflector. The shapes of the reflectors have originated from a parabolic surface. In general, the efficiency of a reflector is measured with reference to its reflection factor. It is also to be noted that this reflector plays a very critical role in distribution of light and thus, the surface should be maintained clean and free of corrosion and scaling. Further, the shape of the parabolic reflector is determined by the constant of parabola. Plastic reflectors are manufactured by injection molding or compression molding process followed by reflective layer coating. [0006] The basis of the headlamp assembly light is the light source. Its geometry and location determine which optical systems can reasonably be used to distribute the luminous flux on the road space. The major technological breakthrough in bulb technology is incandescent lamps, Halogen lamps, high intensity discharge tubes and latest light emitting diode (LED) technologies. Further, Headlamp assembly has a bezel. Though the bezel is not a primary component of headlamp, it has a very critical role in the functioning of the reflector. Further, the reflector is anchored to the case of the headlamp assembly by using adjustable screws and has to be free to move (vertical adjustment) for aiming and adjustment purpose. The bezel thus acts as a spacer in between the reflector and the lens with aesthetics. All the components as discussed above are mounted in a casing. Casing of a headlamp assembly provides for mounting the light sources and reflectors while maintaining their relative positional accuracies.

[0007] Generally, in a two-wheeled vehicle configured for usage under high speeds, the headlamp assembly required is also of high configuration with greater luminosity and also with greater wide-angle view. One such requirement of the headlamp assembly for vehicles operable at higher speeds can be achieved by introducing dual lights inside the headlamp assembly. However, such dual lights make the headlamp assembly heavy. Supporting of the heavier headlamp assembly with dual lights there within becomes a cumbersome exercise. In order to achieve the same, a number of parts including numerous brackets and other supporting structures have to be incorporated. Doing the same again increases the number of parts and also cost in achieving such a complex design. Further, the heavier headlamp assembly always tends to sag downwardly dislocating from its originally assembled position. Such a sagged headlamp assembly may interfere with the surrounding parts that are disposed lower to the headlamp assembly. Furthermore, if the headlamp assembly is not compact and tends to heat up again and again, it calls for frequent servicing and also may lead to replacement of the light sources, lens, etc.

[0008] Generally, in order to achieve better luminous efficiency, the number of LEDs also tends to increase accordingly; however, light condensing ability of LED lights is poor and hence it is undesirable to use LEDs as a high beam light source. Further, in the conventional form of light sources the amount of heat generation during operation is more which in turn can also impact the LED, resulting in shorter life of LED. Furthermore, with the conventional design for the headlamp assemblies it was difficult to achieve complex design which is even compact and functional due to the space constraint and optimum positioning of the headlamp assembly. This also reduces the degree of freedom when designing the front panel of the vehicle as the size of the headlamp is not compact. Generally, LED is used with the traditional headlamp assembly due to which the Headlamp performance has steadily improved. However, this cannot efficiently protect the oncoming traffic from being dazzled. Also, the assembly time for the headlamp and the cost involved in manufacturing combination headlamps is more. The headlamps have provisions for high beam and low beam. However, in the absence of a control mechanism the light leaks; producing glares and increasing the chances of an accident with the oncoming vehicle. Also, in the known configurations of headlamp assemblies, due to various layout constraints such available space for headlamp assemblies and other components, the low beam is not positioned at an optimum location with reference to the reflector which can create a dark zone of about 3-4 meters near the front wheel of the vehicle. Hence, it becomes difficult for the rider to spot any hindrance on the road while driving. [0009] Also, addition of other subsidiary lights in the vehicle results in an increase in the number of parts involved for mounting and housing, etc. More number of parts ultimately increases the assembly time. Also, multiple parts lead to vibration and rattling which causes damage to the components attached, this increases the cost involved for servicing and replacing those damaged components. Furthermore, the numbers of operations required for joining multiple parts are more which even involves separate structural brackets to hold individual subsidiary lights e.g. Daytime running lamp (DRL) assembly or position lamps. Hence, with more number of parts the overall vehicle weight increases, reducing the vehicle efficiency. The placement of Printed Circuit Board (PCB) in the headlamp assembly also plays a very critical role in determining the luminous efficiency of the headlamp. If the PCB is not positioned at the optimum location the light is exposed to the oncoming rider’s eye, which can result in an accident.

[00010] Hence, there is a need for an improved headlamp assembly which is compact, capable of generating a better visual luminous efficiency and is able to overcome all above-mentioned problems and other problems of known art.

[00011] It is to be noted that in the ensuing description, the present invention is usable in a step-through type vehicle exemplified in the form of a two wheeled scooter type motorcycle for illustration and is not limited to a saddle type two wheeled vehicle. Further “front” and “rear”, and “left” and “right” referred to in the ensuing description of the illustrated embodiment refer to front and rear, and left and right directions as seen in a state of being seated on a seat of the scooter type motorcycle. Furthermore, a longitudinal axis, except otherwise mentioned, refers to a front to rear axis relative to the said motorcycle, while a lateral axis, except otherwise mentioned, refers generally to a side to side, or left to right axis relative to the said motorcycle. Similarly, a vertical axis refers to a ground to sky axis relative to the motorcycle. Various other features and embodiments of the present subject matter here will be discernible from the following further description thereof, set out hereunder. The detailed explanation of the constitution of parts other than the subject matter, which constitutes an essential part, has been omitted at suitable places. [00012] Generally, a two or three wheeled vehicle includes a frame assembly made up of several tubes welded together for supporting the body of the vehicle. A lower half of the front portion of the vehicle has a steerable front wheel and at least one driven rear wheel which is driven by a driving force generated by a power assembly. The front wheel of the vehicle is axially supported at a lower end of a front suspension, and the front suspension is pivoted in a steerable manner in a head pipe of the motorcycle frame. Meanwhile, the vehicle frame assembly is covered by a plurality of motorcycle body covers including a front panel, a rear cover, an under-seat cover, a left side cover, a right-side cover and a bottom cover. The right-side cover is symmetrical to the left side cover.

[00013] The upper half of the front portion of the vehicle comprises of a handle bar assembly attached to an upper end of the head pipe. The handle bar assembly and a seat assembly are supported at opposing ends of the frame assembly and a generally open area is defined there between known as floorboard, which functions as a step through space. The seat assembly for a driver and a pillion is placed rearward to a fuel tank and rearwardly of the floorboard. A storage compartment is provided below the seat assembly for storing useful articles. A side trim member laterally beneath the floorboard is provided to cover the lower frame members from being visible. The side trim member is laterally present on both sides of the vehicle; however, only one is visible in the side view. A rear fender is accommodated at the rearmost end of the motorcycle to partially cover the rear wheel. Likewise, a front fender covers the front wheel. For the safety of the user and in conformance with the traffic rules, a headlamp assembly in the front portion of the vehicle and a tail light in the rear portion of the vehicle is also provided.

[00014] According to an embodiment of the present invention, a headlamp assembly is present at a front end of the scooter type vehicle. The headlamp assembly is situated below the handlebar assembly and above the front wheel. In one of the embodiments of the present invention the headlamp assembly comprises of a housing portion. As per one of the embodiments of the present invention a reflector is snap fitted to the housing portion. As per one of the embodiments the reflector is detachably attached to the housing portion with the attaching means, e.g. screws. According to one of the embodiments of the present invention, the headlamp assembly has provisions for accommodating one or more PCBs. As per one of the embodiments of the present invention at least one front position light (FPL) printed circuit board (PCB) is detachably attached to the reflector via attaching means, e.g. guides, snap fitting, etc. In one of the embodiments of the present invention 3 FPL PCBs (Left FPL PCB, Right FPL PCB, Bottom FPL PCB) are detachably attached to the reflector via attaching means, e.g. guide, snap fitting, etc. As per one of the embodiments of the present invention at least one LED is additionally provided on each of the FPL PCBs (Left FPL PCB, Right FPL PCB and Bottom FPL PCB). As per one of the embodiments of the present invention two LEDs are additionally provided on the Bottom FPL PCB. According to one of the embodiments of the present invention the Bottom FPL PCB is additionally positioned parallel to the ground.

[00015] In one of the additional embodiments of the present invention at least one light guide is detachably attached to the reflector via attaching means, e.g. snap fitting. In one of the additional embodiments of the present invention two light guides (Left Light Guide, Right Light Guide) are detachably attached to the reflector via attaching means, e.g. snap fitting. As per an aspect of the present invention the Light Guides are substantially Inverted ‘L’ in shape and are positioned facing opposite to each other, such that the Left Light Guide and the Right Light Guide are mirror images of each other when the vehicle is viewed from the front side in a longitudinal axis. As per one of the embodiments of the present invention the Left and Right Light Guides each additionally have at least one opening for the FPL PCBs from where the light from LEDs enters in the Left and Right Light Guides. In one of the embodiments of the present invention, the Left Light Guide additionally has an opening in the long arm for the LED light to enter from the Bottom FPL PCB. In one of the embodiments of the present invention, the Right Light Guide additionally has an opening in the long arm for the LED light to enter from the Bottom FPL PCB. As per an aspect of the present invention the Left Light Guide has an opening in the short arm for the LED light to enter from the Left FPL PCB. In one of the embodiments of the present invention, the Right Light Guide additionally has an opening in the short arm for the LED light to enter from the Right FPL PCB.

[00016] As per an aspect of the present invention, the length of both arms (Long arm, short arm) of Left and Right Light Guide is proportional and at an optimum angle with a smooth curve, this efficiently controls and simplifies guiding the light through the Light Guides. In addition, the space of ‘V’ shape formed between the Light Guides (Left Light Guide, Right Light Guide) provides path for guiding the wires for LEDs. This results in better wiring routes and eliminates need of excess wires, which enables a compact design and additionally leads to cost reduction. It must also be noted that as per one of the present invention the long arm and short arm of Light Guides are positioned such that the long arms of both the Light Guides (Left Light Guide, Right Light Guide) are inclined away from each other and converging near the Bottom FPL PCB. As per one of the embodiments of the present invention, the Left FPL PCB is additionally positioned such that it is at an angle which is matching with the Opening for LED in the Left Light Guide. As per one aspect of the present invention, the Right FPL PCB is positioned such that it is at an angle which is matching with the Opening for LED in the Right Light Guide.

[00017] According to an embodiment of the present invention additionally a reflector is detachably attached to the housing portion via attaching means, e.g. screws, snap fitting, etc. Further, the purpose of a reflector in a headlamp assembly is to collect as much light as possible from the light source. As per one aspect of the present invention, the reflector comprises of at least two compartments (Left, Right). As per one aspect of the present invention, the Left compartment is further comprising of two sections (Left Low beam compartment, Left High beam compartment). As per one aspect of the present invention the Left low beam compartment is positioned above the Left High beam compartment in the Left compartment. As per one aspect of the present invention, the Right compartment is further comprising of two sections (Right Low beam compartment, Right High beam compartment). As per one aspect of the present invention the Right low beam compartment is positioned above the Right High beam compartment in the Right compartment. This enables to remove the dark zone which can otherwise be formed if the Low beam compartment (Left, Right) was placed below the High beam compartment (Left, Right). As per one aspect of the present invention the Low beam compartment and the High beam compartment are divided by a pair of separating members (Right separating member, Left separating member). The pair of separating members (Right separating member, Left separating member) prevents the light leaking phenomenon by creating a distinguished wall between the light coming from the LED1, LED2. The pair of separating members (Right separating member, Left separating member) also plays a very critical role as it acts as a base for the PCB2 for the High beam compartments (Left, Right). As per one aspect of the present invention the pair of separating members (Right separating member, Left separating member) are at an inclined angle from the ground, however the PCBs (PCB1, PCB2) are detachably attached to the housing portion via guides which are parallel to the ground. This is very important as the LEDs will perform in the most efficient manner since the PCBs are parallel to the ground even though it’s in an angled bezel. This assembly prevents the oncoming rider from being exposed to the direct light coming from the LEDs.

[00018] According to one aspect of the present invention, two main lamp PCBs (PCB1, PCB2) are detachably attached to the reflector via attaching means, e.g. guides, snap fitting, etc. As per one aspect of the present invention, the PCB1 has plurality of LEDs attached to it. As per one aspect of the present invention the PCB2 has plurality of LEDs attached to it. In one of the embodiments of the present invention the Left (Low beam, High beam) and Right (Low beam, High beam) compartments additionally have an opening in the upper surface for the light coming from the LEDs (A, B, C, D) attached to the PCBs (PCB1 and PCB2) respectively. According to one aspect of the present invention the LEDs are placed such that they are at a focus point with reference to the reflector. This location of LED enables the reflector to collect most possible amount of light from the light source for getting the maximum beam range and distribution of light. The LEDs are positioned in the PCBs which are at a plane parallel to the ground. According to one aspect of the present invention the light rays coming from the LED falls at the parabolic reflector. The parabolic reflector produces a parallel beam of the light which is reflected with maximum efficiency since the light source is located at the focus. The reflector is of optimum focal depth which exploits major portion of light emitted and enables to achieve high efficiency levels by the headlamp assembly. Also, the parabolic area of the reflector ultimately results in increasing the overall area covered by the light. Since the LED is positioned parallel to the ground surface at low beam compartment (Left and Right compartment) the dark zone can be eliminated as the light can now reach directly from the start of the wheel. This provides better visibility and minimizes the chances of any accident due to any external factors.

[00019] According to one aspect of the present invention the Bezel is detachably attached to the housing portion. As per one aspect of the present invention a main lens is detachably attached to the Housing portion via attaching means, e.g. snap fitting, adhesive material, etc. The vehicle headlamp assembly has clear lens which are made of plastic. This lens is more light weight and provides cost advantages. As per one aspect of the present invention the bezel is sandwich mounted between the main lens and the housing portion. The bezel provides a support structure to the main lens.

[00020] According to an embodiment of the headlamp assembly has one or more reflector surfaces. In one of the aspect of the present invention one or more light guides are provided to guide the light generated by the LEDs. As per one aspect of the present invention an inner lens is detachably positioned over the light guide. According to one aspect of the present invention a bezel is detachably attached to the housing portion. According to an aspect of the present invention a lens is detachably attached to the housing portion. Eurther, the placement of the LEDs in the headlamp front housing portion is arranged to achieve maximum optimization of the place available inside the headlamp front housing portion. [00021] The aforesaid and other advantages of the present subject matter would be described in greater detail in conjunction with an embodiment of a two wheeled vehicle with the figures in the following description.

In one of the embodiments of the present invention said Feft low beam compartment (501a) is positioned above said Left High beam compartment (501b) in said Left compartment (501). As per one of the embodiments of the present invention, said Right compartment (502) further comprises of two portions, i.e. a Right Low beam compartment (502a) and a Right High beam compartment (502b). In one of the embodiments of the present invention said Right low beam compartment (502a) is positioned above said Right High beam compartment (502b) in said Right compartment (502). This enables to remove the dark zone which can otherwise be formed if said plurality of Low beam compartments (501a, 502a) was placed below the said plurality of High beam compartments (501b, 502b). As per one of the embodiments of the present invention said plurality of Low beam compartments (501a, 502a) and said plurality of High beam compartments (501b, 502b) are divided by a plurality of separating members i.e. Left separating member (503) and Right separating member (504). In one of the embodiments of the present invention, said plurality of separating members (503, 504) prevents the light leaking phenomenon by creating a distinguished wall between the light which is coming from a plurality of LEDs (A, B). In one of the embodiments of the present invention, said plurality of separating members (503, 504) also play a very critical role as it acts as a mounting base for a PCB (505) for said plurality of High beam compartments (501b, 502b). As per one of the embodiments of the present invention the pair of separating members (503, 504) are at an inclined angle from the ground, however said PCB (505) is detachably attached to said housing portion (201) via guides which are parallel to the ground. Similarly, in one of the embodiments of the present invention a PCB (506) is detachably attached to said housing portion (201) via guides which are parallel to the ground. This is very important as the LEDs will perform in the most efficient manner since the PCBs (505, 506) are parallel to the ground even though it’s in an angled bezel. This assembly prevents the oncoming rider from being exposed to the direct light coming from the LEDs.

[00032] According to an embodiment of the present invention, said plurality of main lamp PCBs (505, 506) are detachably attached to the reflector via attaching means, e.g. guides, snap fitting, etc. As per one of the embodiments of the present invention, a First PCB (506) has plurality of LEDs (A, B) and the PCB (506) is attached to said Second PCB (506). In one of the embodiments of the present invention said Second PCB (505) has plurality of LEDs (C, D) attached to said Second PCB (505). In one of the embodiments of the present invention said Left Low beam compartment (501a), said Left High beam compartment (501b), said Right Low beam compartment (502a) and said Right High beam compartment (502b) have openings (O) in the upper surface for the light coming from said plurality of LEDs i.e. A, B, C, D respectively attached to said PCBs (506, 505) respectively. According to one of the embodiments in the present invention said plurality of LEDs (A, B, C, D) are placed such that they are at a focus point with reference to said reflector (202). This location of said plurality of LEDs (A, B, C, D) enables said reflector (202) to collect most possible amount of light from the light source for getting the maximum beam range and distribution of light. In one of the embodiments of the present invention said plurality of LEDs (A, B, C, D) are positioned on said PCBs (506, 505) which are at a plane parallel to the ground. In one of the embodiments of the present invention the light rays coming from said plurality of LEDs (A, B, C, D) falls at the parabolic reflector (202). The parabolic reflector (202) produces a parallel beam of the light which is reflected with maximum efficiency since the light source is located at the focus. In one of the embodiments of the present invention said reflector (202) is of optimum parabolic focal depth which exploits major portion of light emitted and enables to achieve high efficiency levels by said headlamp assembly (116). Also, the parabolic area of said reflector (202) ultimately results in increasing the overall area covered by the light. Since said plurality of LEDs (A, B, C, D) is positioned parallel to the ground surface at said plurality of low beam compartment (501a, 502a) the dark zone can be eliminated as the light can now reach directly from the start of the wheel. This provides better visibility and minimizes the chances of any accident due to any external factors.

[00033] Thus, according to an embodiment the headlamp assembly (116) has one or more reflector compartments (501a, 501b, 502a, 502b). In one of the embodiments of the present invention one or more light guides (203, 204) are provided to guide the light generated by plurality of LEDs. In one of the embodiments of the present invention said bezel (302) is detachably attached to said housing portion (201). According to an aspect of the present invention said main lens (303) is detachably attached to said housing portion (201). Further, the placement of the LEDs in said headlamp assembly (116) is configured to achieve maximum packaging of the place available inside said housing portion (201) thereby achieving a compact lamp assembly with improved performance & durability.

[00034] It is to be understood that the aspects of the embodiments are not necessarily limited to the features described herein. 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.
