  • Patent number: 12239200
    Abstract: A nail lamp for curing UV-curable nail gel uses light emitting diodes (LEDs) that emit ultraviolet light and are relatively lower power. The nail lamp is powered from an exterior power source, such as a wall socket, or by a rechargeable battery pack. A battery compartment of the nail lamp holds the battery pack, which is removable without disassembling the nail lamp. The nail lamp is easily transportable to different locations and can be used even when a wall socket is unavailable. A curing time of the nail lamp is user-selectable. The nail lamp can also include one or more detection sensors to detect a person's hand or foot in a treatment chamber and automatically turn on or off the LEDs.

  • Patent number: 12232588
    Abstract: A nail lamp has a removable, rechargeable battery pack and a translucent shell formed by double-injection molding. The lamp is portable can be operated cordlessly using the battery pack. The translucent shell glows when the lamp's treatment chamber is on. Surface-mounted light emitting diodes (LEDs) illuminate the treatment chamber with multiple wavelengths ultraviolet (UV) light. The battery pack has a USB port which allows a customer to conveniently charge a device (e.g., smartphone) while the customer's nails are being worked on. The battery pack has a battery gauge, which indicates a charge level remaining for the battery. When the battery pack is low on charge, the battery pack can be swapped with a charged battery pack. A battery pack can be charged while inserted in the lamp or removed from the lamp. The LEDs of the nail lamp are passively cooled.
