## Title
Portable light with clip

## Abstract

A portable light is disclosed comprising at least one light emitting diode, a power source, a switch operable for closing an electronic circuit between the power source and the light emitting diode, wherein when the electronic circuit is closed the at least one diode emits light generally about a first axis, and a body adapted to receive the light emitting diode, the battery and the switch, the body comprising a loop portion towards one end thereof defining a loop aperture having an axis which is substantially parallel to the first axis.

## Background
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from U.S. Provisional Application No. 60/742,563 filed on Dec. 6, 2005 the entirety of which is incorporated herein by reference


FIELD OF THE INVENTION
The present invention relates to a portable light with clip. In particular, the present invention relates to a portable light comprising a karabiner like loop at one end.
BACKGROUND TO THE INVENTION
The prior art reveals a variety of light emitting devices in combination with loops and clips for attachment to other objects. Examples of such prior art devices include small flashlights integrated into key chains and pendants, amongst others. One drawback of such prior art devices is that the light source is typically oriented with respect to the loop or the clip such that when the light source is suspended by the clip under its own weight, the light source is directed vertically downward.
SUMMARY OF THE INVENTION
In order to address the above and other drawbacks, there is disclosed a portable light comprising at least one light emitting diode, a power source, a switch operable for closing an electronic circuit between the power source and the light emitting diode, wherein when the electronic circuit is closed the at least one diode emits light generally about a first axis, and a body adapted to receive the light emitting diode, the battery and the switch, the body comprising a loop portion towards one end thereof defining a loop aperture having an axis which is substantially parallel to the first axis.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front plan view of a portable light with clip in accordance with an illustrative embodiment of the present invention;
FIG. 2 is an exploded side view of a portable light with clip in accordance with an illustrative embodiment of the present invention; and
FIG. 3 is a side plan view of a portable light with clip in accordance with an illustrative embodiment of the present invention.



DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS
Referring now to FIG. 1, a portable light with clip, generally referred to using the reference numeral 10, will now be described. The portable light 10 is comprised of a hollow body 12 manufactured from a durable material such as plastic or cast metal which houses a series of light sources as in 14, such as LEDs or the like. The light sources may produce white light, light in a variety of different colours or emit light in the infra-red range. The light sources as in 14 are encased in a transparent lens 16 which is securely mounted to an upper surface 18 of the hollow body 12. A series of buttons (switches) as in 20 are also mounted on the upper surface 18 of the hollow body 12 allowing a user to access functions supported by electronics (not shown) encapsulated within the hollow body 12.
Still referring to FIG. 1, a loop comprised of a karabiner like hook portion 22 is mounted towards one end of the hollow body 12 and defines a loop aperture 24. The hook portion 22 also comprises a spring loaded clip 26 moveable between a normally closed position A and an open position B around a pivot 28. Illustratively, the hook portion 22 comprises a flange 30 which fits snugly yet releasably within the hollow body 12, thereby allowing the hook portion 22 to be removed from the hollow body 12. Referring now to FIG. 2, once the hook portion 22 is removed, the interior of the hollow body 12 can be accessed thereby allowing, for example, batteries as in 32 for powering the light sources 14 to be inserted and removed. This configuration also provides a means during manufacture for inserting electronics into the hollow body 12 which can then be, if required, potted with a suitable potting material in order to improve the resilience of the portable light 10 to moisture and impact.
Note that, in an alternative embodiment the hollow body 12 and the hook portion 22 could be moulded or bonded together. In this alternative embodiment, provision would be made in the lower surface of the hollow body, by way of a removable cover or the like (not shown), in order to access the interior of the hollow body 12 for inserting batteries as in 32 for powering the light sources 14.
Referring now to FIG. 3, the hook portion 22 combined with the spring loaded clip 26 provides a means for quickly attaching and releasing the portable light 10 from a variety of objects, such as belt loops 34 and the like. Additionally, the light sources 14 are positioned to emit light generally normal to the flat body 12 along the indicated axis X which is substantially parallel to the indicated axis Y of the aperture 24. This means that, when the portable light 10 is suspended from a belt loop 34 or the like, light is emitted substantially at right angles away from the object as in 36 to which it is mounted, which provides for improved visibility in a number of applications. Note that although the emitted light is illustratively shown as being at right angles to the surface of the object as in 36 to which it is mounted, in an alternative embodiment a plurality of light sources 14 could be arranged generally about an axis at right angles to the object as in 36 but such that their emitted light is at a lesser angle.
Referring back to FIG. 1, as stated above, the series buttons as in 20 provide access to functions supported by electronics (not shown) encapsulated within the hollow body 12. These functions comprise, for example, different intensities for the light sources, different signalling patterns or signatures, etc..
It is to be understood that the invention is not limited in its application to the details of construction and parts illustrated in the accompanying drawings and described hereinabove. The invention is capable of other embodiments and of being practised in various ways. It is also to be understood that the phraseology or terminology used herein is for the purpose of description and not limitation. Hence, although the present invention has been described hereinabove by way of preferred embodiments thereof, it can be modified, without departing from the spirit, scope and nature of the subject invention as defined in the appended claims.

## Claims
