摘要： 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.
