DESC:TECHNICAL FIELD
[0001] The present subject matter described herein generally relates to a vehicle, and particularly but not exclusively relates to a rear lamp assembly of a vehicle.
BACKGROUND
[0002] Typically, 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. The rear portion of the vehicle, includes a rear lamp assembly facing rearward of the vehicle, along with a pair of rear position lamps configured in vehicle width direction. A battery acts as a source for supplying power to both the head lamp assembly and the rear lamp assembly of the vehicle
[0003] Usually, the rear lamp is wired to the same switch that turns “ON” the head lamp assembly, making the rear lamp function easily without any hassle. Therefore, the rear lamp of the vehicle works on a relay, which implies that the rear lamp turns “ON”, when the headlamp assembly is turned “ON”. This way, the driver does not have to worry about turning “ON” the rear lamp. In case of automatic lighting system, the rear lamp will turn “ON” when the vehicle is turned “ON”. When the vehicle stops or the user applies brake for slowing down the vehicle, the rear lamp glow with a brighter appearance, usually brighter red appearance, compared to a dimmer red appearance when the vehicle was in motion without application of the brakes.
[0004] The rear lamp is a safety aspect of the vehicle. As, the rear lamp illuminate the rear edge of the vehicle to allow other drivers or riders to appropriately gauge the size and shape of the vehicle. In addition, the rear lamp also allows other vehicles to see the vehicle in inclement weather, such as rain or snow. Some, rear lamps have reflective material inside them, which help the rear lamp to amplify the light, allowing them to appear brighter and larger.

DETAILED DESCRIPTION
[00014] Conventionally, the rear lamp assembly including the rear lamp, is electrically operated, usually round in shape, consisting of parabolic reflecting surface, and is disposed on the rear portion of the vehicle, to illuminate the road behind 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, usually by the means of simple symmetric round reflecting surface.
[00015] These days, Light Emitting Diodes (LED) have become a more popular choice for rear lamps. This is because the LED lamps use a smaller amount of energy and last longer than traditional rear lamps. Some of the traditional rear lamps include usage of Halogen lights, which are high intensity discharge lights that use filaments. Some other traditional rear lamps include usage of Xenon lights, which are strong, bright, and higher intensity lights and use an electrical arc compared to a filament. However, LED lights tend to outlive both the Halogen lights and the Xenon lights and use lesser amount of energy.
[00016] Usually, both the front and the rear lamp of the vehicle are the bulkiest and heaviest parts of the illumination system of the vehicle. Because of being bulky and heavy, the front lamp and the rear lamp increase the overall weight of the vehicle and also use a considerable space to be accommodated in the vehicle.
[00017] Moreover, such bulky and heavy lamps are not desired in some vehicles, such as electric vehicles. Because, reduced weight of any electric vehicle is directly proportional to the increase in the performance of the vehicle. Therefore, lesser the weight of the vehicle, more is the performance of the vehicle. Also, it is desired to have a compact illumination system, particularly a compact rear lamp, because the rear portion of a vehicle is usually sleeker as compared to the front portion of the vehicle. Resultant to which, usable space to occupy electronic components at the rear portion of the vehicle is reduced as compared to the usable space provided on the front portion of the vehicle.
[00018] Therefore, it is desired to have a compact rear lamp in a vehicle, to increase the available usable space for mounting electronic components. Moreover, a compact rear lamp also aids in giving the vehicle, a sleeker appearance, making the overall vehicle aesthetically pleasing. Also, a sleeker vehicle would ultimately have a reduced drag force because of which ultimately, the performance of the vehicle would increase. This is because, with a sleeker rear portion, the otherwise opposite drag force acting on the vehicle, will be less because of minimized obstruction present on the rear portion, when the vehicle is in motion.
[00019] Moreover, most of the conventional vehicles include the rear lamp that usually give two-dimensional surface emission. Resultant to which, sometimes it is difficult for a person at a distance to clearly identify the vehicle moving in front of him, especially when the vision is compromised due to bad weather. This sometimes, can be detrimental, especially in situations where the person driving the vehicle in the front slows down or applies brakes, but the person driving behind him, being at a distance and a high speed, fails to identify the front vehicle slowing down or applying brake.
[00020] Therefore, it is also desired to have a vehicle having a compact lamp assembly, particularly placed on the rear portion of the vehicle, giving a more identifiable surface emission so that the rear vehicular light can be identified from a distance.
[00021] Hence, there is a need to address above circumstances and problems of the known arts.
[00022] The present subject matter has been devised in view of the above circumstances as well as solving other problems of the known art.
[00023] The present subject matter discloses about a rear lamp assembly detachably mounted on the style parts or the rear cowl unit of a vehicle. The rear lamp assembly is inclinedly disposed on the rear portion of the vehicle.
[00024] In an aspect of the present embodiment, the rear lamp assembly includes a housing, an inner lens, a bezel, an optical member and an outer lens. The inner lens and the optical member are placed together in an inclined manner, in angular conformity with each other, and held by the bezel. A PCB driver with a plurality of light emitting diode (LEDs) is placed on a bottom region of the housing and placed adjacently below said inner lens.
[00025] In another aspect, the outer lens covers the entire housing along with the internal components.
[00026] In another aspect, the inner lens is broad at one end and tapered at another end.

[00034] Figure 2a to Figure 2b illustrates a rear perspective view of a rear lamp assembly 116, when viewed from the rear of the vehicle 100, in accordance with an embodiment of the present subject matter. The rear lamp assembly 116 includes a housing 202 and an outer lens 201. Both the housing 202 and the outer lens 201 are fixedly attached at a mating portion 204, by snap fit arrangement or by means of fasteners. A plurality of rear lamp mounting provisions 203 are provided on the rear portion of the housing 202. The plurality of rear lamp mounting provisions 203, aid in detachable attachment of the rear lamp assembly 116 with the style parts of the vehicle 100, for example, cowl unit of the vehicle 100 covering rear portion of the vehicle 100, by means of fastening means 200. The rear lamp assembly 116 is disposed in an inclined manner on the rear portion of the vehicle 100. The inclination is such that, when a straight vertical line “X” is drawn perpendicular to the ground, and another line “Y” is drawn touching the outermost edge of the rear lamp assembly 116, then both the lines intersect making an angle ?1, i.e., a first angle. Therefore, the outermost edge of the rear lamp assembly 116 makes a first angle ?1 with a bottom portion of the rear lamp assembly 116 of the vehicle 100. The first angle ranges in between 40 degrees and 50 degrees.
[00035] The housing 202 is made in a stepped manner, to accommodate the internal essential components and at the same time eliminating the need to increase the width of the housing 202, by eliminating unnecessary non-usable space within. Similarly, the outer lens 201 is bulged out at one end to accommodate the internal essential components with respect to their positioning and at the same time eliminating the need to increase the width of the outer lens 201, by eliminating unnecessary non-usable space within. Both the housing 202 and the outer lens 201 aid in providing compactness to the present rear lamp assembly 116.
[00036] Figure 3 illustrates an inner portion of the housing 202 of the rear lamp assembly 116, when viewed from the rear of the vehicle 100, in accordance with an embodiment of the present subject matter. The inner portion of the housing 202, herein called as a housing inner 205, includes a plurality of housing inner upper mounting provision 205aa and a plurality of housing inner lower mounting provision 205bb, along with other plurality of mounting provisions to attach internal components placed within the housing 202. A plurality of fasteners 200 are used to fasten the internal components housed within the housing 202. The internal components comprise a cable holder 206, an air vent 207 and a PCB driver 208 mounted separately on the housing inner 205 of the housing 202.
[00037] The cable holder 206 aids in holding the cables of the other electronic components placed inside the housing 202, in position. Also, the cable holder 206 provides a vent to the cables (not shown) to exit the housing by means of a cutout (not shown) provided in the housing 202, so that the cables can be attached to the power source. The air vent 207 aids in keeping the internal components of the rear lamp assembly 116 within optimal temperature, thereby preventing excessive heating of the internal components. The PCB driver 208 is placed on the bottom portion of the housing inner 205, of the housing 202. The PCB driver 208 houses a plurality of Light emitting diodes (LEDs) 302 (shown in Figure 6a).
[00038] Figure 4 illustrates an exploded view of sub-assemblies of the of the rear lamp assembly 116, in accordance with an embodiment of the present subject matter. The sub-assemblies include an inner lens 209, a bezel 210, and an optical element 211. The inner lens 209, the bezel 210, and the optical element 211 are housed in the housing 202 (shown in Figure 3) and are covered from outside by means of the outer lens 201. The optical element projects rearwards of the vehicle 100.
[00039] The inner lens 209 is a glass lens or a lens made of polycarbonate of about 8 mm to 12 mm width and approximately 100mm to 120mm length. The inner lens 209 is broad at one end and tapered on the other end. Further the inner lens 209 includes an inner lens upper mounting provision 209aa, an Inner lens lower mounting provision 209bb.
[00040] The bezel 210, acts as a holding structure, that holds the inner lens 209 from one end and the optical element 211 from the other end. The bezel 210 also aids in ensuring the rear lamp assembly 116 is a leak proof assembly. The bezel 210 further includes a pair of an extended arms 210a, which are made in angular conformity of the upper portion of the optical element 211, so that the holding arms 210a can firmly hold inclinedly placed optical element 211.
[00041] The optical element 211 is covered with an optical element meshed portion 211a on the outer portion. The optical element meshed part 211 are made of a plurality of small diamond shaped optical elements meshed together. The optical element meshed portion 211a aid in providing a three-dimensional light dispersion. The optical element 211 further includes an optical element upper mounting provision 211aa and an Optical element lower mounting provision 211bb. The optical element 211 is approximately of 20 mm to 30mm width and is approximately of 125mm to 135mm length.
[00042] Figure 5 illustrates an exploded view of the rear lamp assembly 116, in accordance with an embodiment of the present subject matter. The present illustration illustrates that the housing 202 first houses the PCB driver 208 on its inner most bottom region and the air vent 207 and the cable holder 206 approximately on the middle inner portion, wherein all the three parts are mounted separately. Then the inner lens 209, and the optical element 211 are held together by the bezel 210 in an inclined manner. Then the bezel 210 along with the inner lens 209, and the optical element 211 are housed in the housing 202. Then the outer lens is fixedly attached to the whole housing 202. Then the whole rear lamp assembly 116 is detachably mounted on the style parts of the vehicle 100.
[00043] Figure 6a to Figure 6b illustrates a sectional view of the internal components of the rear lamp assembly 116, in accordance with an embodiment of the present subject matter. The inner lens 209 is placed inclinedly in the housing 202 (shown in Figure 5), in such a manner that if a horizontal plane “M” is drawn parallel to the ground plane of vehicle 100, and another line “N” is drawn angular and in tangent contact with the outermost part of the outer lens 201, then both lines while intersecting make an angle ?2, i.e., a second angle. Therefore, the outermost edge of the optical member 211 makes a second angle ?2 with a bottom portion of the rear lamp assembly 116 of the vehicle 100. The second angle ranges as per an embodiment is in between 40 degrees and 50 degrees. A plurality of LEDs 302 is disposed above the PCB driver 208, and the PCB driver 208 along with the LEDs 302 are placed just below the inner lens 209. This inclination of the inner lens 209 and the optical element 211 along with the placement of the PCB driver 208 adjacently below the inner lens 209, ensures achievement of compactness in the rear lamp assembly 116.
[00044] The optical element 211, is also placed inclinedly in angular conformity with the inclined inner lens 209. The optical element 211 being composed an optical element meshed portion 211a outwardly and an optical element streaked portion 211b inwardly. The optical element streaked portion 211b are streaked type projection which line the inner portion of the optical element 211.
[00045] Figure 6b, illustrates that the optical element 211, the driver PCB 208 and the inner lens 209 are housed together inside the housing 202 and protectively covered by means of the outer lens 201 and conforming to the profile of the optical element 211.
[00046] Figure 7a illustrates light dispersion pattern in a conventional rear lamp assembly 300. Conventionally, the PCB driver 208 is placed approximately vertically in the housing of the rear lamp assembly. Therefore, in order to bring homogeneous dispersion of light a greater number of LED lights 302, and a bigger PCB driver is required, as compared to the present subject matter, which ultimately increases the overall cost of the rear lamp assembly 300. Moreover, in the PCB driver 208 itself is Inclined to achieve compactness, then the light 301 from the LEDs 208 will be travelling direct on the ground, without giving much visibility of the rear lamp assembly 300, for a person behind the vehicle.
[00047] Figure 7b illustrates light dispersion pattern in an embodiment of the present subject matter. Since the PCB driver 302, is placed below the inner lens 209. The light 301 emitted by the LEDs 302 placed above the PCB driver 302 is captured by the inner lens 209. Then the light 301 travels within the inner lens 209 and is further emitted from the transverse face of the inner lens 209 towards the outer lens 201. Because of the inclined placement of the inner lens 209, the light first travels towards the outer lens 201 in an inclined manner, focused towards the ground.
[00048] Then the streak lining, i.e. the optical element streaked part 211b, captures the light 301 and changes the direction of most of the light, and now most of the travelling light 301 becomes parallel to the ground, thereby providing a homogeneous dispersion of light. Then the light 301 is travels through the optical element meshed part 211a. The optical element meshed part 211a, because of its diamond shaped meshed structure, provides a sparkling and three-dimensional effect, thereby further providing a three-dimensional dispersion of light 301. Ultimately the light passing from the optical element meshed part 211a passes through the outer lens 201 and the outer lens provides required magnification to the travelling light 301.This three-dimensional dispersion of light, along with the magnified light, makes the rear lamp assembly 116 more identifiable for a person approaching the vehicle 100 from behind.
[00049] 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.
