[001] The present disclosure, in general, relates to a wall mounting luminaire and more
particularly, to a wall mounting luminaire with multiple mounting adjustments to
facilitate multiple orientation. The wall mounting luminaire can be easily converted into
wall light, task light, ambient light, corner lamp, etc. as per the usage application.
BACKGROUND OF THE INVENTION
[002] Today LED lighting technology is rapidly replacing traditional incandescent and
fluorescent lights. Even in the tube lighting applications, instead of being filled with inert
gas and mercury as found in fluorescent tube lights, the LED tube lights are mercury-free.
Thus, it is no surprise that LED tube lights are becoming highly desired illumination
option among different available lighting systems used in homes and workplace, which
used to be dominated by traditional lighting options such as compact
fluorescent light bulbs (CFLs) and fluorescent tube lights. Benefits of the
LED tube lights include improved durability and longevity, and far less energy
consumption, therefore, when taking into account all factors, LED lights would be
considered as cost effective lighting option.
[003] There are several types of LED luminaires available in the market for various uses,
such as, wall light, task light, ambient light, corner lamp etc. However, each of the
available luminaires has rigid structural features which are not adaptable for more than
one type of use.
[004] The wall light is currently prominently used in houses and offices to illuminate
the entire room. Often it is required to illuminate a particular part of the room or to dim a
particular part of the room. The wall lights which are prominently used in our houses and
offices are not capable of this functions. Further, wall lights cannot be adapted to be used
3
in corners of a room due to its rigid structure. Furthermore, the wall lights usually provide
a certain glare which makes people present in the room uncomfortable while looking at it
directly.
[005] For applications such as reading, the user needs a luminaire which is more focused
on the reading material, such as book. For this purpose, reading lamps are used. The
reading lamps occupies unnecessary space on the reading desk. Further, reading lamps
cannot be used for other purposes.
[006] Task lightning is a new trend in the luminaire market, wherein increased
illumination is provided to better accomplish a specific task. Interior designers often use
task lightning to create visual effects in a room. One of the most popular dramatic effect
includes illuminating a vertical surface such as a wall with light. If a wall-lightning
luminaire is mounted in a ceiling, it falls into a class of lighting luminaire known as down
lights. If a wall-lightning luminaire is positioned near the floor, it is called an up-lights.
No luminaire is currently available in the market which can be used as both up-lights and
down lights, simultaneously.
[007] Therefore, there is a need to develop a wall mounting luminaire which can
individually perform functions of a wall light, a task light, an ambient light or a corner
lamp and also obviate other drawbacks mentioned above.
OBJECT OF THE INVENTION
[008] It is therefore an object of the present invention, to solve the aforementioned and
other drawbacks existing in the conventional luminaires.
[009] Another primary object of the present invention is to provide a wall mounting
luminaire with multiple mounting adjustments to facilitate multiple orientation.
4
[0010] Yet another objective of the present invention is to provide a wall mounting
luminaire which can individually perform either of the functions of a wall light, a task
light, an ambient light or a corner lamp.
[0011] Yet another object of the present invention is to provide a wall mounting luminaire
which can transform into either one of a wall light, a task light, an ambient light or a
corner lamp just by twisting the modules.
[0012] Yet another object of the present invention is to provide a wall mounting luminaire
with indirect light source to eliminate glare.
[0013] Still another object of the present invention is to provide a wall mounting
luminaire which does not occupy unnecessary space.
[0014] Yet another object of the present invention is to provide a wall mounting luminaire
which is compact in design.
[0015] Yet another object of the present invention is to provide a wall mounting luminaire
having tunable white light with dimming option.

WORKING OF THE INVENTION
WORKING OF THE WALL MOUNTING LUMINAIRE AS WALL LIGHT
[0049] To use the wall mounting luminaire 100 as a wall light, the wall mounting
luminaire 100 is secured on the wall through the mounting bracket 101. The luminaire
module arms 103 preferably make 1800 angle (as shown in Figure 5) with each other
while used as a wall light. The user can adjust the color temperature of the light according
to his/her need as the wall mounting luminaire 100 is provided with tunable white light
function. Further, user can switch ON/OFF one or more than one of the plurality of arrays
11
of LEDs as per his/her requirements. Furthermore, brightness of the arrays of LEDs can
also be adjusted as per the requirement of the user.
WORKING OF THE WALL MOUNTING LUMINAIRE AS CORNER LIGHT
[0050] The wall mounting luminaire 100 as per the present subject matter can be used as
a corner light as the luminaire module arms 103 can make 90o angle (as shown in figure
6) with each other. To use the wall mounting luminaire as a corner light, the wall
mounting luminaire is secured on the wall through the mounting bracket 101 with the
luminaire module arm making 90o angle with each other. The user can adjust the color
temperature of the light according to his/her need as the wall mounting luminaire 100 is
provided with tunable white light function. Further, user can switch ON/OFF one or more
than one of the plurality of arrays of LEDs as per his/her requirements. Furthermore,
brightness of the arrays of LEDs can also be adjusted as per the requirement of the user.
WORKING OF THE WALL MOUNTING LUMINAIRE AS TASK LIGHT
[0051] The wall mounting luminaire 100 as per the present subject matter can be used as
a task light as the luminaire module arms 103 can make any angle in the range of 0o to180o
with each other (as shown in figure 7). To use the wall mounting luminaire 100 as a task
light, the wall mounting luminaire is secured on the wall through the mounting bracket
101 with the luminaire module arm 103 making any angle between 0o to180o with each
other. The user can adjust the color temperature of the light according to his/her need as
the wall mounting luminaire 100 is provided with tunable white light function. Further,
user can switch ON/OFF one or more than one of the plurality of arrays of LEDs as per
his/her requirements. Furthermore, brightness of the arrays of LEDs can also be adjusted
as per the requirement of the user. This task light can be used as both up-lights and/or
down-lights.
[0052] The present wall mounting luminaire 100 has multiple mounting adjustment to
facilitate multiple orientation. The angled profile at first end of the luminaire module arm
103 gives angular flexibility to achieve different orientation to cater different applications
12
such as wall light, task light, corner light and ambient light. The wall mounting luminaire
100 creates indirect light source which eliminates glare as it does not hit the eyes of the
user directly.
[0053] Most of the task light, such as reading lamp, available in the market nowadays
occupies vertical space. The present wall mounting luminaire 100 is mounted on the wall
and is capable to use as a reading lamp, wherein the luminaire module arm 103 making
an angle of 0o with each other (refer to Figure 8). The wall mounting luminaire save space
for the user.
[0054] 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
13
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.”
[0055] 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
