Abstract
Description
- The present invention is in the field of lighting devices for portable electronic or computing devices.
- Compact electronic devices with a viewing screen or keypads have become very common and quite popular. Such devices have been popular for a number of years in connection with hand-held, portable, battery-powered gaming devices. A well-known example of such a device, that has sold millions of units, is the GAME BOY™ device sold by Nintendo. More recently, other electronic devices have also included viewing screens, such as portable video cameras and cellular phones. And, of course, portable computers have long had viewing screens. Although the complexity and cost of such devices can vary greatly, it is common for such devices to use a generally flat, liquid crystal display screen.
- Flat, liquid crystal display screens work very well in a well-lit area. However, when such devices are used in dimly lit areas, or at night, it can be difficult, if not impossible, for a user to see anything in the viewing screen. This problem is magnified when such a screen is used in a device that is meant to be portable, and especially when it is a small device.
- If a portable device is sufficiently complex, and generally more expensive, such as a portable laptop computer, the device can include lighting within the actual device. An example of such lighting is a portable laptop computer with a backlit screen. However, this solution is not always economically practical, nor does it necessarily solve the problem in smaller devices. Also, if an electronic device does not have a viewing screen, then this option is not even available.
- To solve this problem, especially in connection with hand-held, portable, battery-powered gaming devices, a number of different solutions have been proposed. Such solutions have typically included add-on devices with their own source of electrical power. These devices can be designed to fit onto the electronic device or be designed for use in connection with the electronic device. However, because such devices use their own source of electrical power, they tend to be rather bulky and heavy. In addition, the second source of electrical power increases cost and creates the possibility of another source of power failure.
- Accordingly, there is a long felt need for a simple, economical, device that can illuminate portable electronic or computing devices without the drawbacks associated with prior illumination devices.
- A need also exists for a pass-thru illumination apparatus that not only illuminates objects associated with the portable electronic or computing device such as the screen, keyboard, paperwork, etc. but also allows peripherals to be attached to the portable electronic or computing device through the illumination apparatus.
- An aspect of the invention involves a method of illuminating an object associated with a portable electronic or computing device with a pass-thru illumination apparatus, the portable electronic or computing device including a first port in communication with a power source. The method includes providing a pass-thru illumination apparatus including a first plug with a second port, a body connected to the first plug, and an illumination device attached to the body; plugging the first plug of the pass-thru illumination apparatus into the first port of the electronic or computing device to power the illumination device with the power source of the electronic or computing device to illuminate an object associated with the electronic or computing device; and plugging a second plug of a peripheral into the second port of the pass-thru illumination apparatus to accomplish at least one of powering the peripheral and communicating the peripheral with the electronic or computing device.
- Another aspect of the invention involves a pass-thru illumination apparatus for illuminating an object associated with a portable electronic or computing device including a first port in communication with a power source. The pass-thru illumination apparatus includes a first plug to plug the pass-thru illumination apparatus into the first port of a portable electronic or computing device, the first plug having a second port to receive a second plug of a peripheral to accomplish at least one of powering the peripheral by the power source of the electronic or computing device and communicating the peripheral with the electronic or computing device; a body connected to the first plug; and an illumination device attached to the body to be powered by the electronic or computing device for illuminating an object associated with the electronic or computing device.
- A further aspect of the invention involves a method of using an adapter to interface a pass-thru illumination apparatus with a first port of a portable electronic or computing device. The method includes providing an adapter configured to mate at a first end with a first plug of a pass-thru illumination apparatus and configured to mate at a second end with a port of the portable electronic or computing device; connecting the first end of the adapter to the first plug of the pass-thru illumination apparatus; and connecting the second end of the adapter to the first port of the portable electronic or computing device.
- A further aspect of the invention involves a method of using an adapter to interface a peripheral with a port of a pass-thru illumination apparatus. The method includes providing an adapter configured to mate at a first end with a plug of a peripheral and configured to mate at a second end with a port of the pass-thru illumination apparatus; connecting the first end of the adapter to the plug of the peripheral; and connecting the second end of the adapter to the port of the pass-thru illumination apparatus.
- A still further aspect of the invention involves an adapter for interfacing a pass-thru illumination apparatus with a first port of a portable electronic or computing device. The adapter includes an adapter body including a first end configured to mate with a first plug of a pass-thru illumination apparatus and a second end configured to mate with a first port of the portable electronic or computing device.
- A yet further aspect of the invention involves an adapter for interfacing a pass-thru illumination apparatus with a plug of a peripheral. The adapter includes an adapter body including a first end configured to mate with the plug of the peripheral and a second end configured to mate with a port of a pass-thru illumination apparatus.

- FIG. 4 is a perspective view of the pass-thru illumination apparatus shown in FIG. 2 in conjunction with a pair of adapters that may be used with the pass-thru illumination apparatus.
- FIG. 1 illustrates how a preferred embodiment of the present invention can be used with a portable electronic game device, such as a GAME BOY™ device. Although this drawing depicts a portable electronic game device, the invention is adaptable to any portable electronic device that has a utility power jack in electrical connection with a power source, such as, but not by way of limitation, a cellular phone, a personal digital assistant (“PDA”), a digital camera, or a video camera.
- In the preferred embodiment shown in FIG. 1, the electronic device1 has a
viewing screen 2, a power source and a utility power jack. The power source and utility power jacks are not visible and are shown generally as 3 and 4, because their location and configuration will vary depending upon the design of a given portable electronic device. The power source 3 may be self-contained, such as batteries in a battery compartment. The power source 3 may or may not be augmented by a plug-in capability to a non-portable power source, such as a wall outlet. - The illumination apparatus, shown generally as5, includes a plug, shown generally as 6, for plugging the
illumination apparatus 5 into the utility power jack 4 of the electronic device 1. The exact configuration of theplug 6 should be designed so as to mate with the utility power jack 4 and create a mechanical and electrical connection between the utility power jack 4 and theplug 6 when theapparatus 5 is plugged into the electronic device 1. - The
illumination apparatus 5 also includes abody 7 and anillumination device 8. Thebody 7 connects theillumination device 8 to theplug 6, and the body is preferably comprised of a flexible arm. Theillumination device 8 is electrically connected to the utility power jack 4 through theplug 6 and thebody 7 so that theillumination device 8 is powered by thepower source 2 when theillumination apparatus 5 is plugged into the electronic device 1. The electrical connection between theillumination device 8 and theplug 6 can be by any suitable means, such as by a wire (not shown). It is especially preferred that thebody 7 can be adjusted, when theapparatus 5 is plugged into the utility power jack 4, to adjust the height and/or the angle of theillumination device 8 relative to the electronic device 1. - In the preferred embodiment of the present invention, the
illumination device 8 is comprised of a light emitting diode (“LED”) 9 housed in acase housing 10. Thehousing 10 can also include suitable electronics, such as a resistor 11, or a regulator (not shown) for varying the intensity of light given off by the LED. In an especially preferred embodiment, the LED 9 is a white light diode. The housing can also include additional features, such as a diffuser lens 9, or a magnifier (not shown). - When the
plug 6 of theillumination apparatus 5 is plugged into the utility power jack 4 of the electronic device 1, it necessarily occupies the connection that the utility power jack 4 would otherwise provide to a user of the electronic device 1. Because a user of the electronic device 1 might need to connect some other device to the utility power jack 4, it is especially preferred that theplug 6 be constructed so as to include a secondutility power jack 12. The secondutility power jack 12 is adapted to receive a second plug and provide a mechanical and electrical connection for the second plug equivalent to that which is provided by the utility power jack 4. Thus, the secondutility power jack 12 will provide electrical communication for the second plug with the utility power jack 4 when the second plug is plugged into theplug 6 and theplug 6 is plugged into the utility power jack 4. - The present invention is also adaptable to a portable computing device with a display screen that is not illuminated by the portable computing device. In such an embodiment, the illumination apparatus is plugged into a utility port of the computing device in electrical connection with a power source instead of the utility power jack4 of the electronic device 1. In such a device, the utility port can be any port that allows connection of additional products or communication devices, or cables, or any additional accessory or product. The illumination apparatus can have a second utility port adapted to receive a second plug that is in electrical communication with the utility port when the second plug is plugged into the plug and the plus is plugged into the utility port. In all other respects, the structure and function of the illumination apparatus would be the same as for the
illumination apparatus 5 described above in connection with electronic device 1. - With reference to FIGS.2-4, a pass-thru
illumination apparatus 20 constructed in accordance with an additional embodiment of the invention will now be described in conjunction with a laptop ornotebook computer 22. Theillumination apparatus 20 is similar to theillumination apparatus 5 shown in FIG. 1, except theillumination apparatus 20 includes an oval, UFO-shaped light orcase housing 24, a helicalbendable wire body 28, and a pass-thru plug member 32. Thelight housing 24 houses a light source, preferably at least one white LED. The pass-thru plug member 32 includes afirst plug 34 on aflat side 35 of theplug member 32 and a second jack orport 36 on an opposite, taperedside 38 of theplug member 32. Asupport flange 40 may extend from theflat side 35 of theplug member 32. - In use, the pass-thru
illumination apparatus 20 is plugged into thelaptop computer 22 by plugging thefirst plug 34 of theapparatus 20 into a serial port or first port of thelaptop computer 22. Thesupport flange 40 helps to secure the apparatus to thelaptop computer 22. Afirst adapter 42 may be used to interface thefirst plug 34 with the serial port of thelaptop computer 22 if thefirst plug 34 is not sized to mate with the serial port. Theadapter 42 includes an adapter body having a first end configured to mate with thefirst plug 34 of the pass-thruillumination apparatus 20 and a second end configured to mate with the serial port or first port of thelaptop computer 22. The pass-thruillumination apparatus 20 may include different configuration plugs 34 and/or may be used with a variety ofdifferent configuration adapters 42, e.g., a family of different configuration adapters, to ensure communication of theapparatus 20 withlaptop computers 22 having different configuration ports. Theillumination apparatus 20 draws power through the serial port of thelaptop computer 22 to power and illuminate the light source in thelight housing 24. - A peripheral such as a
keyboard 44 may connect with thelaptop computer 22 through the pass-thruillumination apparatus 20. This may be accomplished by plugging a keyboard orsecond plug 46 at the end of akeyboard cord 48 into thesecond port 36 of theplug member 32. Asecond adapter 50 may be used to interface thekeyboard plug 46 with thesecond port 36 of theplug member 32 if thesecond port 36 is not configured to mate with thekeyboard plug 46. Theadapter 50 includes an adapter body having a first end configured to mate with thesecond plug 46 of the peripheral 44 and a second end configured to mate with thesecond port 36 of the pass-thruillumination apparatus 20. The pass-thruillumination apparatus 20 may includedifferent configuration ports 36 and/or may be used with a variety ofdifferent configuration adapters 50, e.g., a family of different configuration adapters, to ensure communication of peripherals with different configuration plugs with theapparatus 20. - The
keyboard 44 may draw power and/or communicate with thelaptop computer 22 through the pass-thruillumination apparatus 20. Thebendable body 28 may be bent to a desired orientation for ideal lighting of any object(s) associated with thelaptop computer 22, e.g.,laptop screen 52,laptop keyboard 54,peripheral keyboard 44, other peripheral(s), reading materials. Also, if thebendable body 28 becomes uncoiled, thebendable body 28 can be reshaped into a coil by bending and wrapping thebody 28 around a pen, pencil, or similar instrument and removed. - Likewise, with reference specifically to FIG. 3, the pass-thru
illumination apparatus 20 may be plugged into a port of a Personal Digital Assistant (“PDA”) 56 and a peripheral, e.g.,keyboard 44, may be powered by and/or communicate with thePDA 56 via the pass-thruillumination apparatus 20. Similar to the laptop example illustrated in FIG. 2, the pass-thruillumination apparatus 20 may be bent to a desired orientation for ideal lighting of any object(s) associated with thePDA 56, e.g.,PDA screen 58,keypad 60,peripheral keyboard 44, other peripheral(s), reading materials. - Similarly, the pass-thru
illumination apparatus 20 may be plugged into ports of other electronic or computing devices and peripherals may be powered by and/or communicate with the electronic or computing devices via the pass-thruillumination apparatus 20. Theillumination apparatus 20 is then used to illuminate any object(s) associated with the electronic or computing device. Examples of other electronic or computing devices that the pass-thruillumination apparatus 20 may be used with include, but not by way of limitation, remote controls, internet phones, cell phones, non-backlit or insufficiently lit handheld video game devices, calculators, portable electronics with a display or keyboard, and other hand-held devices. - It will be readily apparent to those skilled in the art that still further changes and modifications in the actual concepts described herein can readily be made without departing from the spirit and scope of the invention as defined by the following claims.
