Description

BACKGROUND

1. Field of Invention

The present invention relates generally to a universal serial bus port that is illuminated. More specifically, the present invention relates to a universal serial bus port that is back lighted with a light emitting diode.

2. Description of Related Art

Universal serial bus (USB) is a specification created around 1996 to establish communication between electronic devices and a host controller. The host controller is usually a computer. USB can carry both power and data. It is intended to replace a variety of serial and parallel ports. USB is used to connect computer peripherals such as mice, keyboards, digital cameras, printers, flash drives, and external hard drives to a computer. It has become a common electronic interface for many modern electronic devices and computers.

The standard female USB port has a rectangular opening with a biased opaque white plastic tongue that is enclosed in a metal sheath. There are four electrical contacts on the opaque white plastic tongue. The four electrical contacts extend through four openings in the back of the opaque white plastic tongue and connect to power and data connections. The standard male USB plug has a compatible plug that can only plug into the female USB port in one orientation.

BRIEF SUMMARY OF THE INVENTION

The present invention is an illuminated universal serial bus (USB) port that is illuminated with a light emitting diode (LED). The illuminated USB port comprises a female USB port with a LED disposed directly behind the USB port to illuminate the USB port through the white plastic and existing openings in the USB port without modifications to existing USB port design.

An object of the lighted USB is to provide a USB port that is illuminated. A further object of the lighted USB is to provide an illuminated USB port that is easily located in low light or dark environments. An additional object of the lighted USB is to provide a method of illuminating the inside of a USB port without taking up any font panel space when the USB port is mounted. Another object of the lighted USB is to provide a method to retrofit existing USB port designs with an illumination means. Yet another object of the lighted USB is to provide a means to illuminate a USB port through the white plastic and existing openings from behind the USB port without using any light pipes. Another object of the lighted USB is to provide a means to indicate the power on status of a USB port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description and figures are meant to be illustrative only and not limiting. Other embodiments of this invention will be apparent to those of ordinary skill in the art in view of this description.

As shown in the figures, in the preferred embodiment, the lighted USB comprises a standard dual female USB ports 1 with a light emitting diode (LED) 2 disposed immediately behind the USB ports 1. The LED 2 illuminates the USB ports 1 through the white plastic 5 and the existing openings 3 at the back of the USB ports 1. The USB ports 1 are illuminated without the use of any light pipe. No modification to existing USB port design is required.

A standard female USB port 1 has a rectangular opening 4 with a biased opaque white plastic tongue 5 that is enclosed in a metal sheath 6. There are four electrical contacts 7 on the opaque white plastic tongue 5 that extend through four openings 3 in the back of the opaque white plastic tongue 5 and connect to power and data connections. The LED 2 is positioned behind the opaque white plastic tongue 5 and the four existing openings 3 and illuminates the interior of the USB port 1 through the opaque white plastic and the four existing openings 3. No light pipe is necessary. Furthermore, no additional space on the face area is required around the USB port 1 for the LED 2.

The LED 2 is electrically connected to the 5V power connections behind the USB port 1. When power is available through the power connections, the LED 2 will be illuminated, thereby illuminating the interior of the USB port 1. When power is not available through the power connections, the LED 2 will not be illuminated. The availability of power at the USB port 1 is easily identified by observing the illumination of the USB port 1. After a USB plug is inserted into the USB port 1, the light will be blocked and not be visible.

The lighted USB port enables the USB port 1 to be easily located in low light or dark environments. No modification to existing USB port design is required. The lighted USB port design can be easily retrofitted to existing USB ports without modification of the USB port. Furthermore, since the USB port 1 is illuminated from within the port itself, this design does not take up any front panel space. In addition, since no light pipe is required, this design is compact and takes up very little space behind the USB port 1. The lighted USB can also indicate its power status with an illuminated port indicating power on and a dark port indicating power off.

Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
