Technical Field

The present invention relates to a nail lamp, and more particularly, to a 2-in-1 nail lamp stand, which includes a lamp base assembly to dry nail polish on a plurality of nail surfaces of a user's hand and foot, and a detachable lamp pen to dry nail polish on a specific nail surface of one finger on the user's hand or one toe on the user's foot.

Background

Various methods have been developed to reduce the burden on an individual to nail a fingernail or toenail with nail polish. Specifically, multiple nail coatings are applied sequentially to the nail surface. For example, a layer of base varnish, one or more layers of nail polish, and a layer of protective varnish are applied sequentially to the nail surface. Manicure accessories or accessories, such as beads or stickers, can be adhered to the nail surface prior to applying the protective oil.

It is worth mentioning that all nail coatings must be dried separately. Specifically, to dry each layer of nail coating on the nail surface, the nail surface is typically exposed to an LED lamp or UV lamp. Alternatively, instead of applying nail polish directly to the fingers or toes, the user may attach custom nails, made of plastic or gel, to the nail surfaces of the user's hands and feet, respectively, and then apply nail polish to the custom nail surfaces.

For example, U.S. issued patent 8,534,299 provides a custom fingernail made of a moldable element made of UV transparent material, such as glass, clear plastic, or clear acrylic, and adapted to be attached to a fingernail surface and secured with an adhesive that applies UV radiation through the custom fingernail between the fingernail surface and the custom fingernail. In other words, UV light is also commonly used to attach the custom nail to the user's nail surface. The inventor of the present invention also provides an artificial nail plate and a cured glue composition, U.S. application No. 15/916,216, which discloses an elongated glue and an X-glue nail plate, preferably adapted to be applied to a nail surface by applying LED lights for 30 seconds.

Existing nail lights typically include a light source supported within a light chamber, wherein multiple nail surfaces may be placed under the light source within the light chamber while simultaneously drying the nail coatings on the nail surfaces. In other words, existing nail lights provide a relatively large area for a user to dry nail coatings on five nail surfaces, such as by simultaneously drying a primer on the nail surface. However, existing nail lights have some disadvantages. Since existing nail lights provide a large area of drying area, the light intensity within the light chamber may not be evenly distributed, such that the nail coating on the curved nail surface may not be simultaneously evenly and completely dried. Particularly when different nail polish is applied to different nail surfaces, the nail polish may be unevenly dried due to the curvature of the nail surface, the difference in coating thickness, and the uneven light distribution. More, it is difficult for the user to determine the optimal location to place the finger for the coating area that is relatively most evenly distributed and directed to the particular nail surface that needs to be dried. For example, when a nail bead is adhered to the nail surface, the edge of the nail bead must be dried to hold the nail bead on the nail surface. Likewise, when a protective layer is applied to the nail beads, existing nail lights are not effective in drying the nail coating on the irregular contours of the nail beads. Accordingly, some users may attempt to apply UV or LED light to the desired area of the nail surface of each finger one by one using a separate light source, such as a battery-powered flashlight, but this takes a significant amount of time to complete the drying step. However, it is also a hit when the user has finished applying the nail coating but has found that the flashlight is not powered.
