Abstract
A compact portable LED nail curing lamp has surface-mounted light emitting diode (SMD LED) lights. The lamp provides fast and consistent results producing high gloss finish and even curing of nail polish (e.g., UV-curable gel polish). The nail lamp has a micro USB port, which can be used to power the lamp using a wall adapter, car charger, laptop USB port, or mobile power bank for ultimate portability. In an implementation, a system includes a compact LED nail curing lamp and a mobile power battery pack. The system also includes a cable to connect the nail lamp and the mobile power battery pack. The battery pack provides portable power to the nail lamp so that the nail lamp can be used portably, such as during travel or on an airplane when a wall outlet is unavailable.
Claims26
A nail lamp comprising:
- an upper housing, comprising a light diffusing material;
- a lower housing, adapted to mate with the upper housing, wherein when the upper and lower housings are mated, an enclosed space is formed between the upper and lower housings;
- and
- a printed circuit board, coupled to the lower housing and positioned in the enclosed space between the upper and lower housings, wherein the printed circuit board comprises a plurality of exterior-facing light emitting diodes and interior-facing emitting diodes,
- wherein exterior-facing light emitting diodes are positioned on a first surface of the printed circuit board, while the interior-facing emitting diodes are on a second surface of the printed circuit board that is opposite to the first surface,
- light emitted by the exterior-facing light emitting diodes strike a surface of the light diffusing material,
- light emitted by the interior-facing light emitting diodes does not strike a surface of the light diffusing material, but rather are directed through apertures formed in the lower housing into a treatment chamber below the enclosed space and the lower housing, where the treatment chamber will receive a hand or foot of a user of the nail lamp, and the hand or foot of a user will be exposed to light emitted by the interior-facing light emitting diodes.

A nail lamp comprising:
- an upper housing, comprising a shell, an opening for a power input and a plurality of exterior facing light emitting diodes, wherein the exterior facing light emitting diodes can emit light through the shell;
- the shell comprises a light diffusing material that scatters light from the exterior facing light emitting diodes to provide a more uniform illumination across an exterior surface of the shell compared to an uneven illumination without the light diffusing material;
- a lower housing that forms a cavity, coupled to the upper housing, comprising openings through which a plurality of cavity facing light emitting diodes can emit light through, wherein the cavity comprises sufficient width to accommodate five fingers of a human hand placed on a flat surface;
- circuitry, enclosed between the upper and lower housing, comprising at least one printed circuit board comprising the cavity facing and exterior facing light emitting diodes;
- a button,
- a control circuit, coupled to the button and the power input,
- a timer, coupled to the control circuit;
- and
- a rechargeable battery coupled to the control circuit.

A nail lamp comprising:
- an upper housing, comprising a translucent light-diffusing material;
- a lower housing, adapted to mate with the upper housing, wherein when the upper and lower housings are mated, an enclosed space is formed between the upper and lower housings;
- and
- a printed circuit board, coupled to the lower housing and positioned in the enclosed space between the upper and lower housings, wherein the printed circuit board comprises a plurality of exterior-facing light emitting diodes and interior-facing emitting diodes,
- the exterior-facing light emitting diodes emit visible light comprising a visible, non-ultraviolet wavelength, and the interior-facing emitting diodes emit ultraviolet light,
- the exterior-facing light emitting diodes are positioned on a first surface of the printed circuit board, while the interior-facing emitting diodes are on a second surface of the printed circuit board that is opposite to the first surface,
- the interior-facing emitting diodes emit light in a first direction, the exterior-facing light emitting diodes emit light in a second direction, and the first direction is opposite of the second direction,
- light emitted by the exterior-facing light emitting diodes strike a surface of the translucent light-diffusing material,
- light emitted by the interior-facing light emitting diodes does not strike a surface of the translucent light-diffusing material, but rather are directed through apertures formed in the lower housing into a treatment chamber below the enclosed space and the lower housing, where the treatment chamber will receive a hand or foot of a user of the nail lamp, and the hand or foot of a user will be exposed to light emitted by the interior-facing light emitting diodes.
