DESC:FIELD OF DISCLOSURE
The present disclosure generally relates to a lighting system used in a vehicle. Particularly, the disclosure relates to a lighting system for lighting an area of a cowl of a two-wheeler vehicle.

BACKGROUND
A two-wheeler vehicle such as a motorcycle is generally equipped with a lighting system such as a head light and a tail light. However, the conventional lighting system does not include any auxiliary lighting for lighting the areas immediately around the headlight area of the cowl. The conventionally known auxiliary lighting systems are generally fitted inside the headlamp area for protecting delicate elements thereof such as Printed Circuit Board (PCB) and Light Emitting Diode (LED) from dust, moisture and other foreign matter.
However, conventional auxiliary lighting systems mounted on the cowl and disposed immediately around the headlight area of the cowl do not provide provisions for preventing the foreign matter such as dust and moisture from coming into contact with delicate elements and electronic circuitry such as Printed Circuit Board (PCB) and Light Emitting Diode (LED) of the auxiliary lighting system and damaging the delicate elements of the auxiliary lighting system. Further, the conventionally known auxiliary lighting systems require a plurality of LEDs for generating a continuously varying lighting pattern on a cowl area of a two-wheeler vehicle.
There is a need for an auxiliary lighting system that may be easily assembled on the cowl area for illuminating an area adjacent the head lamp. Furthermore, there is a need for an auxiliary lighting system that has provisions for preventing foreign matter such as dust and moisture from coming into contact with and damaging the delicate elements such as the Printed Circuit Board (PCB) and the Light Emitting Diode (LED) of the auxiliary lighting system. Still further, there is a need for an auxiliary lighting system that has a longer service life. Further, there is a need for an auxiliary lighting system that exhibits varying lighting pattern. Further, there is a need for an auxiliary lighting system for generating a continuously varying lighting pattern on the cowl area of a two-wheeler vehicle by utilizing fewer LEDs.

Referring to Figures 4a and 4b cavities/slots “C” are provided on the cowl 10 for receiving the lighting sub-system 20b. From the Figures 4a and 4b, it is clear that the lighting sub-systems 20a and 20b can be separately mounted on respective sides of the cowl 10 each configuring a lighted profile on each side of the cowl 10. Figure 5 illustrates a schematic representation depicting the position of the lighting sub-systems 20a and 20b of the auxiliary lighting system with respect to the cowl 10, wherein each lighting sub system configures lighted profile extending on a corresponding side of the cowl 10.
Figure 6 illustrates the assembled view of the auxiliary lighting system 20 along with various elements thereof. Figure 7 illustrates another isometric view of the auxiliary lighting system 20. Figure 8 illustrates a light guide (22a, 22b) of a lighting sub-system of the auxiliary lighting sub-system (20a, 20b).
Referring to Figures 1-8, the various views of the auxiliary lighting system 20 for illuminating area around the head lamp in accordance with the present disclosure are illustrated. The auxiliary lighting system 20 for illuminating area around the head lamp in accordance with the present disclosure includes a lighting sub-system 20a for configuring a first illuminated profile and a second lighting sub-system 20b for configuring a second illuminated profile, where the first profile and the second profile are disposed adjacent to the headlamp. The lighting sub-system 20a includes a light guide 22a, a printed circuit board (PCB) 24a, a printed circuit board casing 26a, a first light emitting diode 28a, a frame 30a and a plurality of spaced apart mounting apertures 32a configured on the frame 30a.
The lighting sub-system 20a is assembled on the cowl 10 of the two-wheeler vehicle. More specifically, the lighting sub-system 20a is fitted inside a slot or cavity “C” extending in the body of the cowl 10. The frame 30a is received in the slot configured on the body of the cowl 10 and the spaced apart mounting apertures 32a configured on the frame 30a registers with the holes (not shown) configured on the cowl body 10 to receive mounting bolts (not shown) and facilitate mounting of the frame 30a on the cowl body 10. The light guide 22a and the printed circuit board casing 26a are assembled to the frame 30a. Particularly, the light guide 22a, the frame 30a and the printed circuit board casing 26a are assembled together to configure an air tight enclosure that encloses delicate elements such as the first light emitting diode 28a and the printed circuit board (PCB) 24a and protects them from foreign matter, moisture and other detrimental environmental conditions.
The printed circuit board (PCB) 24a is housed inside the printed circuit board casing 26a and is connected to an electrical cable of the cable harness that provides electrical power to the printed circuit board (PCB) 24a. The printed circuit board (PCB) 24a in turn controls the first light emitting diode (LED) 28a connected thereto. The printed circuit board casing 26a is generally made of opaque material to hide the printed circuit board (PCB) 24a housed therein.
The light emitted by the light emitting diode LED 28a passes through the enclosure configured by the light guide 22a and the frame 30a. The light generated by the light emitting diode LED 28a travels through the light guide 22a and away from the light emitting diode LED 28a. Due to curved wall configuration of the light guide 22a and the frame 30a, the light repeatedly strikes the light guide 22a that is having a transparent body of polycarbonate glass material. In accordance with a preferred embodiment, the light guide 22a is having a transparent body of Polymethyl Methacrylate (PMMA) material. With such configuration, every time the light strikes the light guide 22a, a portion of the light is transmitted through the light guide 22a while the remaining portion passes through the enclosure configured between the light guide 22a and the frame 30a thereby forming a curved pattern of light with intensity thereof diminishing from area near the LED 28a to area away from the LED 28a. The light guide 22a is so disposed on the cowl 10 that the light bends as it travels away from the light emitting diode LED 28a. Such configuration of the light guide 22a utilizes inherent nature of the light to vary its intensity as it strikes the walls of the light guide 22a to produce a continuously, varying light pattern. It is envisaged to provide a light guide 22a filled with an inert gas such as Neon. Further, such configuration results in diffused lighting effect. With such configuration, the lighting system 20 creates an appealing visual effect, especially when it is seen from far away distance. Such a configuration does not require any additional cover or protection for protecting the lighting system from dust, moisture or any other detrimental environmental conditions.
The lighting sub-system 20b is structurally and functionally similar to the lighting sub-system 20a. More specifically, the lighting sub-system 20b includes a light guide 22b, a printed circuit board (PCB) 24b, a printed circuit board casing 26b, a second light emitting diode 28b, a frame 30b and a plurality of spaced apart mounting apertures 32b configured on the frame 30b. Accordingly, for the sake of brevity of the present document, the constructional configuration of the lighting sub-system 20b is not described in detail. The first light emitting diode 28a and the second light emitting diode 28b are centrally disposed on the cowl and are used for illuminating profiles extending in opposite directions, accordingly with such configuration only one LED acts as a source of light for configuring an illuminated profile on each side of the cowl 10.
Figure 9 illustrates the auxiliary lighting system 20 mounted on the cowl 10, wherein intensity of the light varies from area near the center of the cowl to area away from the center of the cowl. The intensity of the light I1 emitted through the portion of the light guide 22a near the center of the cowl, i.e. near the first light emitting diode 28a is different than the intensity of the light I2 emitted through the portion of the light guide 22a away from the center of the cowl, i.e. away from the first light emitting diode 28a.
