FIELD OF THE INVENTION
The present invention is directed toward a booklight for an
eReader, and more specifically, to a booklight for a protective
cover or jacket of an eReader.

20

BACKGROUND OF THE INVENTION
Recently, eReaders such as electronic books have become
increasingly popular. Such eReaders include a display, such
as a liquid crystal display (LCD), for displaying the contents
or text of an electronic book.
In many eReaders, the display does not include a backlight.
Instead, the eReader relies on ambient light for rendering the
text of the eReader visible to the user. In instances in which
sufficient levels of ambient light are present, the user may not
have any difficulty reading the display of the eReader. However, in other instances, a user may find it difficult to view the
text of the eReader in some conditions in which the level of
ambient light is not sufficient to illuminate the screen of the
eReader.
Some common approaches to improve lighting include
using conventional booklights designed, for example, for
hardcover books. Such conventional booklights often include
spring loaded clamps that may be suitable for attaching a
portable light to a conventional hardcover book. However,
such conventional booklights may be difficult to attach to an
eReader and in some cases may result in damage to, or
scratching of, the housing or screen of the eReader.
Moreover, an eReader is designed to be lightweight, portable, and compact. However, such conventional booklights
can be awkward and cumbersome to carry or transport along
with the eReader. As such, a user may not wish to carry these
conventional devices with them, thereby leaving the user with
no supplemental light source in instances in which ambient
light is limited or reduced.
Also, many conventional booklights do not uniformly light
the display of the eReader, which may lead to fatigue or strain
on the user when trying to read an eReader under low ambient
light conditions.

SUMMARY OF THE INVENTION
The present invention can address and may solve these and
other problems with the conventional devices by providing a
booklight for an eReader, and more specifically, to a
booklight for an eReader jacket.
These problems and others are addressed by the present
invention, a first exemplary embodiment of which is directed
to a booklight for a protective cover for an eReader, wherein
the protective cover includes a pocket for supporting the

60

which require little power to operate and can maximize the
lifespan of the light source, and indeed, may never need
replacing.
Aspects of the present invention can be configured to use,
for example, a single, standardAAA battery that can provide,
for example, equal to or greater than 20 hours of operating
time.
The present invention also provides a booklight having
improved lighting characteristics, such as increased uniform
lighting. For example, the present invention can provide a
booklight including a mirrored reflector and optical quality
dome lens for uniformly distributing the light from the light
source toward the eReader screen.
The present invention also can provide a booklight having,
for example, multiple light intensity settings for the light
source. For example, an aspect can include a three-position
switch including two light intensity settings (for example, a
'high' setting and a 'low' setting) and an 'off setting. Other
aspects can include three or more light intensity settings. In
this mauner, the present invention provides a booklight that
can provide ample illumination in various ambient light conditions, thereby providing greater flexibility and adjustability
for the user. Additionally, the present invention provides a
booklight that can minimize or reduce the power consumption, thereby extending the battery life, for example, by
reducing the light intensity in instances in which a greater
amount of ambient light is available.
The present invention is configured to work seamlessly
with a protective jacket or cover for an eReader.
An exemplary embodiment of the booklight includes a slim
support arm or base sized to match a pocket sewn or formed
in an interior surface of a protective cover for an eReader. The
pocket can be configured to receive a base of the booklight
such that the booklight can be easily and effortlessly carried
with the eReader, for example, at all times. The booklight
pocket can be conveniently located behind the eReader such
that the support arm does not interfere with the use of the
eReader. The exemplary embodiments can be configured to
receive and seamlessly integrate and store the booklight
within the protective cover, for example, in the spine of the
protective cover when the eReader is not in use. In this manner, a lightweight, durable, and compact booklight can be
easily collapsed and stored inside the protective cover along
with the eReader, thereby providing a booklight that is easily
and conveniently carried or transported along with the
eReader, while also protecting the booklight from damage.
Thus, a user of an eReader can easily and conveniently illuminate the screen of the eReader in instances in which the
level of ambient light is limited or reduced.
Other features and advantages of the present invention will

The present invention now is described more fully hereinafter with reference to the accompanying drawings, in which
embodiments of the invention are shown. This invention may,
however, be embodied in many different forms and should not
be construed as limited to the embodiments set forth herein;
rather, these embodiments are provided so that this disclosure
will be thorough and complete, and will fully convey the
scope of the invention to those skilled in the art.
Referring now to the drawings, FIGS. 1A-19D illustrate
exemplary aspects of a booklight for an eReader.
As shown in FIGS. 1A-3D, an exemplary embodiment is
directed to a booklight for a protective cover for an eReader.
The exemplary booklight can be configured to work seamlessly and integrally with the protective cover of the eReader.
The exemplary booklight comprises a base, a light assembly housing 40 having a light source, a manipulatable neck 30
coupled between the base and the light housing assembly, and
a base tab 20 rotatably coupled to the base. The base tab 20
can includes a first end 22 rotatably coupled to the base tab 20,
and a second end 24 extending from the first end 22. As shown
in FIG. lA, the second end 24 is a free end 24. At least a
portion of the free end 24 is configured to engage a pocket of
the protective cover, as shown for example in FIG. 3A.

US 8,047,670 B2

The light assembly housing 40, base 10, and base tab 20
can be constructed from lightweight durable ABS plastic or
other suitable materials. The manipulatable neck 30 can be
formed from plastic, metal, or other suitable materials.
A size and shape of a perimeter of the portion of the free
end 24 substantially corresponds to a size and shape of the
pocket of the protective cover. In an exemplary embodiment,
the free end 24 includes a substantially flat plate portion
configured to engage the pocket of the protective cover. In
other embodiments, the base tab 20 can have other shapes,
such as a rod-shape, a wire-shape, a wire-shape configured to
form a perimeter surface corresponding to the shape of the
pocket, etc.
As illustrated in FIGS. 2A-2D, the base tab 20 can be
rotatable about an axis of rotation that is transverse to the
longitudinal axis of the base 10. For example, in an exemplary
embodiment, the first end 22 of the base tab 20 can be rotatably coupled to the base 10 by a swivel joint. In another
exemplary embodiment, the first end 22 of the base tab 20 can
be rotatably coupled to the base 10 by a ball and socket joint.
An exemplary embodiment of a protective cover 100 for an
eReader is illustrated in FIGS. 3A-3D. The protective cover
100 can include, for example, a pocket for supporting the
booklight. For example, the protective cover 100 can include
a pocket 120 for receiving the base tab 20 of the booklight
such that the booklight can be easily and effortlessly carried
with the eReader, for example, at all times. The pocket 120
can be formed, for example, at an upper end of the interior
surface of the rear cover 104 such that the book light can be
positioned to extend from the upper end of the spine toward
the lower end of the spine of the cover. In other embodiments,
the pocket 120 can be formed at other locations on the interior
of the rear cover 104, or at locations on the interior of the front
cover 102. The pocket 120 can be formed on the same cover
as the mounting system or on a different cover than the cover
having the mounting system.
The pocket 120 can be integrally formed or sewn into the
interior surface of the cover or coupled to the interior surface
of the cover, for example, by another adhering means, such as
using a glue, adhesive tape, etc.
The pocket 120 includes an open end 120a adjacent to the
spine of the protective cover 100 for receiving the base tab 20
of a booklight. The pocket 120 can include a closed end 120b
at an opposite end from the open end 120a. In other embodiments, both ends of the pocket can be open ends. A shape of
the pocket 120 can be configured to correspond to a shape of
the base tab 20 of the booklight.
As shown in FIG. 3B, in operation, the base tab 20 of the
booklight can be inserted into the pocket 120 until the
booklight is positioned along the spine of the protective cover
100, thereby securing the booklight to the protective cover. In
this manner, the protective cover 100 can seamlessly integrate
and store the booklight within the protective cover 100 in the
spine of the cover when the cover 100 is in the closed position.
In this way, the present invention provides a protective cover
100 including an integral booklight that is compact and portable.
When the cover 100 is in the flat open position or the full
open position, the light assembly housing 40 can be moved
into a position to illuminate the display of the eReader in
several ways. For example, the light assembly housing 40 can
be moved into position to illuminate the display of the
eReader by flexing or bending the manipulatable neck 30 of
the booklight while the booklight is in the stored position.
Additionally, as shown in FIG. 3B, the booklight can be
pivoted or swiveled about the base tab 20, thereby moving the
booklight from a stored position in which the booklight is

aligned with the spine of the cover 100 and into an open
position in which at least a portion of the booklight extends
away from the cover 100 such that the booklight can be
positioned to light the display of the eReader. The flexible
neck 30 then can be moved into an optimal position to focus
the light and illuminate the display of the eReader by flexing
or bending the manipulatable neck 30 of the booklight while
the booklight is in the open (i.e., pivoted or swiveled) position. The booklight can be pivoted or swiveled into numerous
positions, depending on the desired position of the light housing assembly for illuminating the display of the eReader. The
cover assembly of the booklight and the protective cover will
be described in greater detail below.
With reference to FIGS. 4A-4E and SA-SE, the base tab 20
and the base 10 of the booklight will now be described.
The base tab 20 can have a substantially L-shaped crosssection. In this embodiment, the free end 24 is substantially
perpendicular to the fixed end. The first end 22 of the base tab
20 can include a front face on a side of the free end 24, and a
