초록 ▼

A computer light for illuminating the computer keyboard or other items in low light environments includes a super bright white LED and a USB plug that enables it to be powered from USB connection ports. The computer light has an elongated neck that is flexible enough to allow the light head to be positioned with ease but stiff enough to allow the light head to assume a fixed position relative to the computer keyboard or other items when it is not being manipulated. The computer light is especially useful for users of portable computers because it is lightweight and energy-efficient, and may be stored in a compact manner.

1. A computer light device comprising: an LED; a flexible cable connected at a first end to the LED; and a plug, compatible with a computer port, connected to a second end of the flexible cable, wherein the flexible cable includes an outer tubing, an inner tubing disposed within a tubular passage of said outer tubing, and a conductive wire electrically coupling the plug and the LED, disposed within a tubular passage of said inner tubing, and wherein the outer tubing comprises a first spiral defining the tubular passage of said outer tubing and the inner tubing comprises a second spiral defining the tubular passage of said inner tubing. 2. The computer light device according to claim 1, wherein an inner diameter of the first spiral is substantially equal to an outer diameter of the second spiral. 3. The computer light device according to claim 2, wherein winding directions of the first and second spirals are the same. 4. The computer light device according to claim 1, further comprising a cylindrical housing for the LED and a lens, wherein a first axial end of the cylindrical housing is fitted over the flexible cable and the lens is fitted onto a second axial end of the cylindrical housing. 5. The computer light device according to claim 4, wherein the lens comprises a front plane that is substantially perpendicular to a center axis of the cylindrical housing and a rear plane that is substantially parallel to the front plane, such that light to be emitted by the LED strikes the rear plane before the front plane. 6. A computer light device comprising: an LED; a plug compatible with a computer port; a flexible cable connected at a first end to the LED and at a second end to the plug; a cylindrical housing for the LED; and a lens, wherein the flexible cable, along an uncoiled portion thereof, includes inner and outer tubings in intimate contact with each other and each of said inner and outer tubings comprises a plurality of windings, and a first axial end of the cylindrical housing is fitted over the flexible cable and the lens is fitted onto a second axial end of the cylindrical housing. 7. The computer light device according to claim 6, wherein the windings of the inner and outer tubings are in the same direction. 8. The computer light device according to claim 6, wherein the flexible cable further includes a pair of insulated copper wires, electrically coupling the plug and the LED, disposed within a tubular passage of said inner tubing. 9. The computer light device according to claim 6, wherein the lens comprises a front plane that is substantially perpendicular to a center axis of the cylindrical housing and a rear plane that is substantially parallel to the front plane, such that light to be emitted by the LED strikes the rear plane before the front plane. 10. The computer light device according to claim 9, wherein the LED is positioned within the cylindrical housing such that a position of the LED's light point source is closer to the flexible cable than the rear plane of the lens.
