The present subject matter described herein, relates to a vehicle lamp housing having a desiccant bag. More specifically, the present subject matter relates to a serviceable desiccant bag assembly in the vehicle lamp housing in which a used desiccant or non-performing desiccant bag can be replaced with a new desiccant bag.
BACKGROUND
[0002] Vehicle lamp or lights are mounted on a vehicle on the front and rear side of the vehicle. Some small lights for the purpose of signals are also provided on the sides of the vehicles. Front mounted lights are called as the headlamps or headlights while the lights mounted on the rear side of the vehicle are called as the tail lights.
[0003] While driving the vehicle, headlamps or headlights help a driver to drive the vehicle on the road during night times or during bad light conditions so that the driver can see the path ahead to avoid any unwanted situation. Similarly, the tail lights help the rear chasing vehicle to identify the vehicle going ahead.
[0004] Now the driver driving the vehicle can see the path ahead of him/her only when the light is of proper intensity so that path ahead is visible properly but sometimes due to the outside harsh environmental conditions like rain, fog, etc., vehicle driving becomes a challenge but it also happens that the headlights or headlamps also becomes foggy due to seepage of moisture inside the headlamps/headlights and visibility of the path gets reduced as this foggy lamps reduces the intensity of lights coming out of it as compared to the normal headlamps.
[0005] Thus it becomes the need to clear this moisture in the headlamps or headlights so that visibility remains proper to guide the driver on the path. Several efforts have been made in this direction to clear the moisture inside the headlamps or headlights. In the prior arts, there is use of the commonly available silica gel or the desiccant bag inside the headlamps or headlights. Desiccant bag inside the headlamps or headlights

absorbs the moisture inside and helps to clear the foggy lights to keep the intensity of light intact so that the driver does not face any difficulty while driving and the path ahead is visible properly.
[0006] However, though in the existing literatures, use of desiccant bag or installing desiccant bag in the headlamps or headlights or serviceability of the desiccant bag is suggested, but the arrangement is complicated and involves fixation of multiple child parts. Further, the existing method does not provide leak proof arrangement and fast installation.
[0007] Therefore, there is a need to provide a vehicle lamp housing assembly in which desiccant bag assembly can be installed in a convenient way within a short span of time.
OBJECTS OF THE INVENTION
[0001] Some of the objects of the present disclosure, which at least one
embodiment herein satisfy, are listed herein below.
[0002] It is an obj ect of the present subj ect matter to overcome the aforementioned
and other drawbacks existing in the prior art systems and methods.
[0003] It is a significant object of the present disclosure to provide a provision for
the serviceability of the pre-fitted desiccant bag assembly.
[0004] It is another principal obj ect of the present disclosure to provide a provision
of slots to cut or remove the pre-fitted desiccant bag assembly.
[0005] It is another object of the present disclosure to provide a provision of fitting
or installing the new desiccant bag assembly after removing the pre-fitted integrated desiccant bag assembly.

Exemplary implementations/embodiments
[0031] The present disclosure relates to a vehicle lamp housing assembly that is
able to facilitate replacement of one or more desiccant bags pre-fitted with the vehicle lamp. This is important because when the desiccant becomes exhausted or is non-performing, moisture retains on the front lens of the vehicle lamp housing assembly thereby reducing visibility. The vehicle lamp housing assembly facilitates easy replacement of such non-performing desiccant bags with new desiccant bag in order to enable adequate visibility of the road conditions while the vehicle is in motion.
[0032] Figure 1 depicts a vehicle lamp housing assembly (100) in accordance with
an embodiment of the present disclosure. The vehicle lamp housing assembly (100) is equipped with a provision of facilitating replacement of one or more desiccant bags already existing in the assembly (100).
[0033] In an aspect, the vehicle lamp housing assembly (100) has pre-fitted
desiccant bags that are mounted on integrated inner surface.
[0034] In an aspect, the vehicle lamp housing assembly (100) comprises of a front
lens (101) and a rear lamp housing (102). The front lens (101) facilitates light in forward direction, whereas the rear lamp housing (102) is connected with the front lens (101) at a front end.
[0035] In an aspect, as shown in Figure 2, the rear lamp housing (102) defines an
inner surface (102-1) and an outer surface (102-O). There is provided one or more mounting provisions on the inner surface (102-1) of the rear lamp housing (102), where the one or more mounting provisions are provided to receive lamp on the inner surface (102-1) of the rear lamp housing (102).

[0036] In an aspect, the inner surface (102-1) of the rear lamp housing (102) also
includes a plurality of desiccant bags (103-1, 103-2) positioned at one or more mounting provisions of the rear lamp housing (102). Generally, the desiccant bags are positioned on flat surface by means of some adhesive. In an embodiment, the flat surface can be provided in horizontal direction (i.e., along vehicle length direction) or in vertical direction (i.e., along vehicle height direction).
[0037] Figure 3 depicts a sectional view A-A of an inner surface of the rear lamp
housing (102) of the vehicle in accordance with an embodiment of the present disclosure. In an aspect, the outer surface (102-O) further defines a continuous flange (104) extended perpendicularly away from the outer surface (102-O) around the plurality of desiccant bags (103-1, 103-2).
[0038] In an aspect, the outer surface (102-O) defines a plurality of screw
receiving mounting holes (105-1, 105-2, 105-3, 105-4) (shown in Figure 1) positioned outside to the continuous flange (104). Exemplary, as shown in figures, there are four screw receiving mounting holes (105-1, 105-2, 105-3, 105-4) provided at four corners of substantially rectangular shaped continuous flange (104).
[0039] In an aspect, the outer surface (102-O) defines a continuous groove (106)
around each of the plurality of desiccant bags (103-1, 103-2) in order to enable removal of each of the plurality of desiccant bags (103-1, 103-2) upon cutting the continuous groove (106) followed by replacement of new desiccant bag in the requisite area. Herein, the continuous groove (106) is a weak portion and facilitates continuous smooth directed cutting as required for replacement of the desiccant bag.
[0040] In an example, the outer surface (102-O) may define a marked area, as
shown with dotted lines in Figure 4, which allows easy cutting of the continuous groove (106) for replacement of the desiccant bag. Thus this service can be availed very easily within a short span of time in automobile service centres.

[0041] In an aspect, the continuous groove (106) is defined inside the continuous
flange (104) on the outer surface (102-O) of the rear lamp housing (102).
[0042] Additionally, the outer surface (102-O) includes a holding portion (107) (as
shown in Figure 4) extending perpendicularly away from the outer surface (102-O) over which the plurality of desiccant bags (103-1, 103-2) are positioned.

accordance with an embodiment of the present disclosure. In an aspect, the desiccant bag assembly (200) comprises of a cap portion (201), an O-ring/gasket (202) and a desiccant bag (203) to be replaced.
[0044] In an aspect, the cap portion (201) is preferably made of plastic and is
having a shape complementary with shape of the existing plurality of desiccant bags (103-1, 103-2) and a portion removed from the vehicle lamp housing assembly having the desiccant bag to be replaced.
[0045] In an aspect, the cap portion (201) defines a plurality of screw mounting
holes (204-1, 204-2, 204-3, 204-4) complementary with position of a plurality of screw receiving mounting holes (105-1, 105-2, 105-3, 105-4) of the vehicle lamp housing assembly (100).
[0046] In an aspect, the desiccant bag (203) is attached with the cap portion (201)
by means of known adhesives. Herein, there is provided the O-ring/gasket (202), where O-ring/gasket (202) is attached with the cap portion (201) and is configured to sandwich in between the continuous flange (104) of the vehicle lamp housing assembly (100) and the cap portion (201). This feature provides a seal proof arrangement at joinery of the desiccant bag assembly (200) and the vehicle lamp housing assembly (100).
[0047] Figure 6 illustrates an example method of serviceability of desiccant bag
in the vehicle lamp housing assembly (100) in accordance with an exemplary embodiment of the present disclosure. The order in which the method is described is

not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method or any alternative method.
[0048] At block (301), the method includes removal of the existing desiccant bag
from the vehicle lamp housing assembly (100) by cutting an outer surface (102-O) of the rear lamp housing (102) along a continuous groove (106) and de-attach the cut desiccant bag by pulling the cut desiccant bag outward with help of a holding portion (107) provided on the outer surface (102-O).

[0053] It should be noted that the description and figures merely illustrate the
principles of the present subject matter. It should be appreciated by those skilled in the art that conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present subject matter. It should also be appreciated by those skilled in the art that by devising various systems that, although not explicitly described or shown herein, embody the principles of the present subject matter and are included within its spirit and scope. Furthermore, all examples recited herein are principally intended expressly to be for pedagogical purposes to aid the reader in understanding the principles of the present subject matter and the concepts contributed by the inventor(s) to furthering the art and are to be construed as being without limitation to such specifically recited examples and conditions. The novel features which are believed to be characteristic of the present subject matter, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures.
[0054] Although embodiments for the present subject matter have been described
in language specific to package features, it is to be understood that the present subject matter is not necessarily limited to the specific features described. Rather, the specific features and methods are disclosed as embodiments for the present subject matter. Numerous modifications and adaptations of the system/device of the present invention will be apparent to those skilled in the art, and thus it is intended by the appended claims to cover all such modifications and adaptations which fall within the scope of the present subject matter.

[0055] It will be understood by those within the art that, in general, terms used
herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as "open" terms (e.g., the term "including" should be interpreted as "including but not limited to," the term "having" should be interpreted as "having at least," the term "includes" should be interpreted as "includes but is not limited to," etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of
A, B, and C" would include but not be limited to systems that have A alone, B alone,
C alone, A and B together, A and C together, B and C together, and/or A, B, and C
together, etc.). In those instances where a convention analogous to "at least one of A,
B, or C, etc." is used, in general such a construction is intended in the sense one having
skill in the art would understand the convention (e.g., "a system having at least one of

A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B."
[0056] It will be further appreciated that functions or structures of a plurality of
components or steps may be combined into a single component or step, or the functions or structures of one-step or component may be split among plural steps or components. The present invention contemplates all of these combinations. Unless stated otherwise, dimensions and geometries of the various structures depicted herein are not intended to be restrictive of the invention, and other dimensions or geometries are possible. In addition, while a feature of the present invention may have been described in the context of only one of the illustrated embodiments, such feature may be combined with one or more other features of other embodiments, for any given application. It will also be appreciated from the above that the fabrication of the unique structures herein and the operation thereof also constitute methods in accordance with the present invention. The present invention also encompasses intermediate and end products resulting from the practice of the methods herein. The use of "comprising" or "including" also contemplates embodiments that "consist essentially of or "consist of the recited feature.
