Reg No IN/PA-1471 , Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle. More particularly, the present invention relates to a tail lamp assembly configured to be received on a rear portion of the vehicle.

BACKGROUND OF THE INVENTION
[002] Tail lamp is a safety aspect provided on vehicles which shows a rear edge of the vehicle to allow other drivers to appropriately gauze shape and size of the vehicle. It provides indications to rear oncoming vehicles with the help of tail function and stop function using either reflector or light guide. A tail lamp assembly having a tail lamp is generally provided at a rear portion of the vehicle.
[003] Conventionally used tail lamp assembly is generally large in size owing to a large number of the internal parts and placement of the internal parts inside the tail lamp assembly. For example, when a printed circuit board with a plurality of light emitting diodes is placed vertically in a tail lamp housing of the tail lamp assembly or a bulb type lamp is placed centrally in the tail lamp housing of the tail lamp assembly, the space occupied by the internal parts is more, and the tail lamp assembly tend to increase in size. Such an increase in size of the tail lamp assembly increases complexity and difficulty in packaging, which is undesirable.
[004] Further, if the printed circuit board with the plurality of light emitting diodes is placed vertically in the tail lamp housing, more number of light emitting diodes are required to provide homogeneous light dispersion throughout a width of the tail lamp assembly. This further increases number of parts. Also, increase in the number of light emitting diodes in the tail lamp assembly increases the need of a heat sink to dissipate the heat produced by such large number of the light emitting diodes. This will further increase part count, which is undesirable.
[005] Therefore, it is clear that large tail lamp assembly increases the weight of the vehicle, cost of the vehicle and part count of the vehicle, which is undesirable. However, as per the regulations, it is important for a tail lamp assembly to have a uniformly spready back light with required intensity. Therefore, the size of the tail lamp assembly cannot be reduced at the expense of compromising the functionality of the tail lamp assembly.
[006] In view of the foregoing, there is a need-felt to provide alternative construction and mounting of the tail lamp assembly to overcome the above-mentioned disadvantages.

[052] The pillion handle mounting bracket 144 is disposed between the rear ends 120b of the upper tubes 120 and extends toward the rear ends 124b of the side tubes 124. The coupler 162 is detachably attached to the pillion handle mounting bracket 144. As shown, the coupler 162 is a L-shaped structure. However, the shape of the coupler 162 should not be construed as limiting and other shapes of the coupler 162 capable of achieving the functionality are within the scope of the present invention. The coupler 162 has an upper surface 162a and a lower surface 162b opposite the upper surface 162a. The one or more first mounting provisions provided on the tail lamp cover 152 are configured to be assembled on the upper surface 162a of the coupler 162. The one or more second mounting provisions 174 provided on the top surface 156 of the tail lamp housing 146 are configured to be assembled on the lower surface 162b of the coupler 162. The one or more third mounting provisions 176 provided on the top surface 156 of the tail lamp housing 146 are configured to be assembled on the tail lamp cover 152. The pair of arms 170 extending from the tail lamp cover 152 in the vehicle front direction are configured to be received on the side tubes 124 of the vehicle 100. The top support member 182 is mounted on the pillion handle mounting bracket 144 and at least partially covers the tail lamp cover 152 in the region covering the top surface 156 of the tail lamp housing 146. As shown, the top support member 182 is mounted on the pillion handle mounting bracket 144 with one or more fasteners F
[053] Figure 13, Figure 14 and Figure 15 illustrates a tail lamp assembly 138 assembled on the rear portion of the vehicle 100, in accordance with an embodiment of the present invention.
[054] As shown the tail lamp assembly 138 is assembled on the rear portion of the vehicle 100. The tail lamp assembly 138 is received on the pillion support bracket 144 and the pair of side tubes 124 of the vehicle 100. Also, the top support member 182 is mounted on the pillion handle mounting bracket 144 and at least partially covers the tail lamp cover in the region covering the top surface of the tail lamp housing.
[055] In an embodiment, the tail lamp assembly 138 acts as a positioning lamp when the vehicle is in ON condition and acts as a stop lamp when the vehicle is in ON condition and a brake is applied. The intensity of light emitted by the tail lamp assembly 138 during a braking operation is at least twice the intensity of light emitted by the tail lamp assembly during a non-braking operation.
[056] Advantageously, in the present invention, light from the printed circuit board 164 is reflected by the reflector 148 and is passed on to the light bar 166, which further increases the intensity of light and help in homogeneous distribution of light throughout the light bar 166. As the light bar 166 is curve-shaped, crystal effect of light is also produced, which usually makes the rear portion of vehicle 100 more identifiable from a distance.
[057] Further, in the present invention, the printed circuit board 164 is placed directly above of the reflector 148, and the light bar 166 is just in front of the reflector 148. As a result, the light travelled is less as all the parts are closer to light bar. Therefore, lesser number of light emitting diodes are required for homogeneous distribution of light in the tail lamp assembly 138.
[058] Furthermore, the pair of arms 170 of the tail lamp cover 152 covers the the rear portion of the side tubes. As a result, the need of the side panels is eliminated. Also, the rear portion of the upper tubes is covered by the tail lamp cover 152.
[059] Furthermore, the tail lamp assembly 138 of the present invention has sleek and compact design. The tail lamp assembly 138 of the present invention also provides homogenous and brighter light using solid crystalline light bar 166. Further, as the lens 150 of the tail lamp assembly 138 has a curved shape, the tail lamp of the present invention provides distinct identity to the vehicle 100. Owing to curved shape, the tail lamp assembly 138 will flush with frame structure of the vehicle, thereby, giving a look that tail lamp assembly is a part of the rear end portion of the vehicle.
[060] Furthermore, because of placement of the tail lamp assembly 138 on the pillion handle mounting bracket 144, the tail lamp assembly 138 is at an elevated height than most of the conventional tail lamp assemblies. Location of tail lamp assembly 138 at elevated height along with the crystal light effect, increases the chance of the vehicle’s identification for a driver of big vehicles such as trucks, lorries etc., by coming in line of sight of such vehicles. Therefore, visibility of the vehicle 100 is improved.
[061] Furthermore, the tail lamp cover 152 covers all remaining portions of the tail lamp assembly 138 except the lens 150, thereby increasing the aesthetics of the vehicle 100.
[062] The claimed invention as discussed above is not routine, conventional, or well understood in the art, as the claimed invention enable the following advantages in addressing existing problems in conventional technologies. Specifically, the technical advantages of better visibility, compactness, durability as heat is dissipated through air vent, aesthetics, better serviceability owing to compact design, easy manufacturability owing to lesser number of parts involved, ease of assembly, weight reduction, part reduction, cost reduction and market attractiveness are achieved by the present invention.
[063] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
