DETAILED DESCRIPTION

The following description of example methods and apparatus is not intended to limit the scope of the description to the precise form or forms detailed herein. Instead the following description is intended to be illustrative so that others may follow its teachings.

In the following description, the terms “water resistant” or “dust resistant” are used. These terms are set under ANSI/IEC-60529 which promulgates certain standards for the degrees of protection granted against intrusion by both solid objects and water. Solid objections include dust, debris, and even accidental conduct by the user's body during use. The terms “water resistant” or “dust resistant” on their own do not necessarily mean that no dust or no water will enter the device.

The terms “light emitting diode” and “LED” are also used in the following description. One of ordinary skill will appreciate that an LED describes a wide variety of two lead semiconductors that emit light by electroluminescence when a voltage differential is applied. LED lights are made in a variety of sizes and typically come in either through-hole or surface mount configurations.

The term “phosphorescence” is also used in the following description. Phosphorescence refers to a mechanism by which a material fluoresces when exposed to radiation. This mechanism is associated with unsuitable energy state transitions in quantum mechanics. A phosphorescence material does not immediately re-emit the radiation it absorbs, but instead absorbed radiation is re-emitted at a lower intensity for up to several hours after the original excitation.

The present application discloses a multi-functional portable thin light. An example foldable light includes an elongated housing with a hinged extension affixed to the upper end of the housing. The extension has a lighting element on its forward facing side and another, a spotlight, on the top end. A switch is positioned on the front side of the housing to engage the lighting elements. A hook is placed on the bottom of the housing to allow the portable light to be located more conveniently to a user.

The example multi-functional folding lighting apparatus may be powered via replaceable or rechargeable batteries. In some instances, the multi-functional folding lighting apparatus includes a charging port into which a connector of a power source can be inserted to supply power to rechargeable batteries of the multi-functional folding lighting apparatus. In other instances, the multi-functional folding lighting apparatus includes a receptacle with conductive contacts into which one or more batteries may be inserted for powering the multi-functional folding lighting apparatus.

In one example situation, when additional lighting is needed as in a power outage or repair task, the user unfolds the extension and activates the portable light by activating the switch. The user selects from the wide light provided by the forward light, which can be used like a lamp, or the more focused light of the spotlight. If the user needs his or her hands, the flashlight may be placed using the magnetic bottom or the rotable hook. After the user is finished, the user can use the charging port to restore power to the device.

Referring now to FIGS. 1-3, an example of a portable light 10 with a foldable thin light wand or extension 12 is shown. The extension 12 is connected to a base 14 by a hinge 20 as shown in the example portable light 10 in FIG. 1. Rear portions of the extension 12 are made of aluminum to form a rear housing of the light wand for heat dissipation and impact resistance.

The hinge 20 in the example portable light can rotate a full 180° from the extended position shown in FIGS. 1-9 to the folded position shown in FIG. 10. The extension 12 is equipped with a pivot that allows it to rotate about its vertical center axis to any angle.

The extension 12 supports a high efficiency COB forward LED 32 used to illuminate as shown in FIG. 1. The forward LED 32 is a high color rendition index chips on board LED. A reflector 34 is positioned around the LED 32 to better direct the light away from the device and into the surroundings. It is contemplated that other light emitting technologies can be used in place of LED 32 including techniques such as arc, incandescent, and florescent bulbs. The reflector 34 is also made of a phosphorescence material which can make it easier to find the portable light 10 in the dark, especially if the device is accidentally turned off.

Another LED, a spotlight 50, is positioned at the top of the extension 12 as shown in FIG. 2. The spotlight 50 is also surrounded by a total reflector 52. The top spotlight 50 on the extension 12 uses a hot melt technique in construction to achieve this. The spotlight 50 is a high power surface mounted LED light that can be used as a conventional flashlight when the portable light 10 is extended.

The base portion 14 contains a lithium-ion rechargeable battery to provide power to the rest of the device. The base portion 14 also has a charging indicator 26 built into design and a switch 16 for activating and deactivating the device. The example portable light 10 contains a lithium ion battery, but could also include another cell or series of cells rechargeable, such as those made of nickel cadmium, or alternatively a single use, non-rechargeable battery, such as those made of alkaline. One of ordinary skill in the art will appreciate that internal components in the portable light 10 also contain charging and discharging circuits, heat sinks, and other electronic components.

A magnetic bottom 42, as shown in FIG. 4, can support the portable light 10 on a variety of surfaces, including on walls or other non-standard surfaces. A rotable hanging hook 40 is hingedly attached to and can extend out from the base portion 14 in order to hang the device from any perch. For example, the hook 40 could be used to hang the portable light 10 from a car frame, table, or any other location where the user needs hands free light provided.

In use, the extension 12 is a light wand that can pivot +180° and −180° for easy handling and storage. This portable light 10 has an ultra-thin design that pivots and folds flat to allow inspection in the tightest work areas. The strong construction design of base portion 14 allows product to drop safely from up to 1.5 meters. The design of portable light 10 prevents contact and the ingress of dust of more than a de minimis amount that provides no harm to the function of the device. It is also shielded from splashing water such that incidental contact with but not submersion in water.

Another example of the portable light is shown in FIGS. 11-20. Unlike the version shown in the earlier figures, this version also includes an aperture 22. In the closed position, when the extension 12 lays against the base portion 14, the aperture 22 is placed in line with the spotlight 50. The alignment of the aperture 22 with the spotlight 50 allows the portable light to function in a way similar to that of a conventional flashlight in the closed position. The aperture 22 can also be used as an additional means of affixing the light to various locations. The aperture 22 can be used, for example, to clip a carabineer to the light.

In the foregoing description, the terms “top,” “bottom,” “front,” “back,” “rear,” “right,” and “left” have been used. These terms are used to give a relative position and orientation to the disclosure. These terms should not be read to impart an absolute position or orientation relative to any other item or location.

Although certain example methods and apparatus have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all methods, apparatus, and articles of manufacture fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents.
