Specification

TECHNICAL FIELD
The present disclosure relates to a field of automobiles. More specifically, the present disclosure relates to a headlamp assembly for motor vehicles which reduces the vibration and rattling sound in the headlamp assembly.
BACKGROUND OF THE DISCLOSURE
The vehicle population across the globe is evolving at a rapid pace. An increase in the vehicular population has also led to an increasing number of ways in which the efficiency of vehicles can be increased. One of those ways is by decreasing the number of assembly parts in a vehicle and increasing the life and efficiency of vehicle parts such as headlamps.
Automotive headlamp components are highly controlled products that must follow performance standards. The primary components of the headlamps are a lens, a reflector, and a bulb. The bulb is the light source of the headlamp and produces light for illumination. It is positioned in the focal point of a parabolic reflector by means of standard holders fixed on the casing of the headlamp assembly. The concentric beams produced by the bulb impact the reflector that directs light to illuminate roads. A plurality of lamps and headlights with reflector housings and lamps accommodated therein is known. Among the examples are incandescent lamps, such as the known H4 lamp, as well as discharge lamps which are becoming increasingly important in the field of motor vehicles.
The detachable mounting of the headlamp in a reflector is to fulfill several requirements. On the one hand, the headlamp must be sufficiently strongly anchored mechanically, so that it remains exactly positioned also when exposed to the forces that may be expected in the field of motor vehicles. On the other hand, it should be possible to exchange the lamp in the reflector with little effort. Particularly important is the exact positioning of the lamp relative to the reflector.

The surfaces of modern, specially shaped reflectors are exactly calculated to image the lamp in an exactly defined location. The positioning of the headlamp deviating from the defined reference point would lead to a strong, undesirable change in the light distribution.
It has been observed that motorcycles having an engine capacity of 800 cc are more prone to produce vibration in the running condition. It also causes the occurrence of a rattling sound in the headlamp, and because of this phenomenon bulb gets damaged. Hence, there is a need to develop a specific type of mechanism which addresses the above-mentioned problem and reduces the vibrations and rattling sound so that the life cycle of the bulb increases.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the prior art.

The lens (8) is used to converges the parallel rays of light from the reflector in a specific direction. The reflector (2) comprises a frontside (2a) and a backside (2b). Further, the reflector (2) defines an opening (2c) at its backside (2b) configured to dispose of the first end (3a) of the light source (3) inside the reflector (2). The opening (2c) is substantially circular and projects a light beam into an interior of the reflector through the light source (3). The reflector (2) regulates the intensity and distribution of an output beam. The light source (3) is positioned in the focal point of the reflector (2) which is a fixed point on the interior of the reflector (2) by means of the holder (5). The concentric beams produced by the light source (3) impact the reflector (2) that directs light to illuminate roads. In an embodiment, the material of the reflector (2) is polyphenylene sulfide (PPS) and the Aluminum metalizing process is used for the reflection of the light.
