The present disclosure generally relates to the field of automobiles. Particularly, the present disclosure relates to a fog and cornering lamp of a vehicle. Further, the embodiments of the present disclosure disclose the construction and mechanism of a fog and cornering lamp for vehicles.
BACKGROUND
The vehicles are equipped with illumination lamps for purpose of illumination and communicating with the other drivers. Some type of illumination lamps are fog lamps, indicator lamps, brake lamps etc. Fog lamps are a type of automotive headlight that is designed to emit light in a bar-shaped beam. The beam is typically designed to have a sharp cut off on top, and the actual lights are usually installed low and aimed toward the ground at a sharp angle. The fog lamp is quite useful in poor visibility conditions caused by rain, fog, snow, or even an excessive amount of dust in the air. Another type of lamps which are quite common in these days are the cornering lamp. Cornering lamp are basically small lamps and whenever the driver corners on one side, they light up to provide extra vision to the driver and thus making his driving experience safer. The cornering lamp function is activated when turning and depending on the steering angle. They illuminate the area to the side of the vehicle considerably increasing safety in the dark or while driving in poor lighting conditions.
The fog lamp and the cornering lamp are present separately in the existing vehicles and performs the desired functions. However, both the fog and cornering lamp requires requisite space and separate lighting modules to achieve the desired function which ultimately makes the lamp taking more area in the front of vehicle and also attracts to additional cost.

Thus, there is need to provide an arrangement which overcomes the above disadvantages and provide a compact lamp structure. Figure 1(a) shows one such type of lamp (100) where the fog and cornering lamp are assembled in a single lamp (100), the lamp (100) including a housing (102), a left side lens (101a), a right side lens (101b), a base (103) placed in the housing, a cap (104), a heat sink (105) supported by the base (102) and a bezel (106) placed adjacent to the lens (101a, 101b). However, in order to achieve the regulatory requirement of cornering function, the lighting arrangement (101) of the existing lamp (100) is required to be titled as illustrated in figure 1(a). The titling of the lamp eventually disturbs the functioning of the fog lamp and also the regulatory requirements of the fog lamp is not meet. Further, due to titling the left side lens (101a) provide the light more than the mandatory requirements and the right-side lens (101b) illuminate less than the mandatory requirement. Thus, there is uneven distribution of light by the lamp (100). Also, manufacturing such type of lamp is complex and involves higher cost.
Further, as illustrated in figure 1 (a) and 1(b), the light source (107) is positioned at the centre of the lamp (100), and which limits the transmission of light rays from -35 to +35° and thereby cannot achieve the light intensity more than this range. Figure 1(c) also a graphical representation of the light intensity of the existing lamp (100) which is only limited from -35 to +35.
Accordingly, there is an immense need to develop an illumination lamp that overcomes the disadvantages associated with the existing illumination arrangements.

Accordingly, the present disclosure provides a system and manipulator described with reference to the figures and specific embodiments; this description is not meant to be constructed in a limiting sense. Various alternative embodiments from part of the present invention.
Referring to the figures 2-21 , the fog and cornering lamp (1) hereafter referred as lamp (1) comprising a housing (2), having an open end (2a) and a close end (2b). The open end (2b) is configured to receive different components of lamp (1) The open end (2a) defines a hollow portion to accommodate one or more components of the lamp (1). The housing (2) is made of any suitable polymetric material and

may have circular, square or rectangular shape. In an embodiment of the present disclosure, the housing is having a rectangular shape. The housing may comprise a lighting module (4) positioned inside the housing. The lighting module (4) comprises at least two light source (3). The light sources (3) positioned proximate to the close end (2b) of the housing, away from the centre of the lamp and towards the bottom side of the lamp. The lighting module may be connected with the power source such as battery of the vehicle for providing the required power to at least two light source (3).
Due to positioning of the light source proximate to the close end of the housing, it provides more area for the light to travel from the light source and the overall illumination of the lamp is enhanced due to shifting of light source towards bottom portion of the lamp. Also, a heat sink (5) is positioned inside the housing (2) which configured to dispense the heat generated by the light sources (3).
As shown in figures 2-11 and in an embodiment of the present disclosure, the lamp (1) may comprise at least one primary lens (6) is disposed in front the light sources (3).

The assembled fog and cornering lamp having two primary lenses placed in parallel manner, as shown in figure 11.
The primary lens (6) may have potato shape or any other suitable shape and is configured to disperse light from the light source as the light from the light source is a fixed beam and the primary lens disperse the light in different directions. The primary lens (6) is configured for merging of the light to provide homogenous illumination, that helps to enhance the illumination of the lamp (1) up to wider angles. The primary lens (6) comprising a curved portion (6a) on the front end of
m

the primary lens (6) and a slant portion (6b) positioned at both ends of the curved portion (6a) in order to wider and enhance the illumination of the lamp (1).
In an embodiment of the present disclosure, the slant portion (6b) is provided on the left and right ends of the curved portion (6a) of the primary lens (6) and is configured to provide the cornering illumination of light intensity more than 60 degrees and fog lamp light intensity of more than 35 degrees in left and right direction.
The primary lens (6) has multiple mountings (6c) configured for mounting the primary lens (6), as shown in figure 8. The primary lens (6) is made of the special polymetric material.

In an embodiment, a plurality of primary lenses (6) is configured for the wider illumination.
Figure 12 illustrates the rays of light from the light source to the outside of the lamp (1). As illustrated in the figure 12, the rays of light from light source travels and strikes the slant portion (6b) of the primary lens and due to phenomenon of total internal reflection travel towards the secondary lens. The ray of light from the left side portion is incident on the portion of secondary lens and is reflected towards the right portion achieving the 60 ° light intensity towards the right side. Similarly, the ray of light from the right side after striking the slant portion is reflected towards the left side portion with 60 ° light intensity towards the right side. Thus, due to presence of slant portion in the primary lens, the lamp is able to achieve -60 ° to + 60 ° of light intensity and hence achieving the mandatory requirement of cornering function requirements.
As shown in figures 5 and 6, the secondary lens (7) is positioned in front of the at least one primary lens (6) and towards the open end (2a) of the housing (2). The secondary lens (7) is configured to illuminate upon receiving light from at least two
11

light sources (3) of the fog and cornering lamp (1). The secondary lens act as a protection to the primary lens and protects the components of lamps from outside environment. The secondary lens does not allow dust, water or any other foreign particles to enter the lamp (1). The primary lens (6) and a secondary lens (7) are supported by the housing (2). The primary lens (6) is mounted between the secondary lens (7) and heat sink (5). The secondary lens (7) is configured to enhance the illumination of the lamp (1).
In an embodiment, the primary lens (6) is an inner lens that is mounted inside the lamp and the secondary lens (7) is an outer lens that is mounted on the outer periphery of the lamp (1). A bezel (8) is placed between the primary lens (6) and the one secondary lens (7). As illustrated in figures 3-4, the fog and cornering lamp (1) comprising a base (11) positioned in the housing (2.
