A light source and a power source are held between upper and lower shells of a fake nail tip. The fake nail tip is provided with its shells hinged open and the light source unactivated. As the shells are brought together, an electrical contact is made between the power source and the light source, which causes the light source to illuminate the fake nail tip. The shells are then fastened together to maintain the light source illuminated.

The present invention is to provide a slow-start photocuring device, comprising: a housing, one or a plurality of UV LED modules, and a switch control module connected to the one or the plurality of UV LED modules. The housing has an inner side provided with an internal cavity, wherein the inner side of the housing is further provided with one or a plurality of openings in one or two sides of the internal cavity. The one or the plurality of UV LED modules provided around the internal cavity, wherein each of the one or the plurality of UV LED modules has a light-emitting side facing the internal cavity. The switch control module comprises a signal modulator, and the signal modulator activates a power buffer mode when receiving a trigger signal, in order to modulate an irradiation power of the one or the plurality of UV LED modules gradually from a first level to a second level.

A novelty light configured to be releasably secured to a user's fingernail and further being configured to have disposed therein a first light source and a second light source. The novelty light includes a support member that is planar in manner having a radius that is approximately equivalent to a human fingernail. Secured to one end of the support member is a lighting chamber. The lighting chamber includes an interior volume having a first internal portion and a second internal portion containing a chemiluminescent material therein. A membrane is disposed within the interior volume of the lighting chamber intermediate the first internal portion and the second internal portion and is configured to be ruptured so as to facilitate the mixing of the chemiluminescent materials so as to produce light. The lighting chamber is further configured with a third internal portion isolated from the second internal portion and first internal portion.

Provided are a decorative nail tip and a manufacturing system and method thereof. The decorative nail tip includes a nail tip layer shaped like a nail. A convex outer surface of the nail tip layer is a decorative surface. The nail tip layer includes a flexible portion and a rigid portion which are sequentially arranged in a nail tip direction. The decorative nail tip has a flexible end and a rigid end, and thus can fit the nail and has an orientation function. During use, the decorative nail tip can fit the edge of the nail by means of its flexibility, such that the possibility of stretching, folds, air holes, hollows and edge warping is reduced; and after being cured, the whole nail tip layer can decorate the nail in a rigid and plump form.

The present invention provides a polymer compound peeling agent usable for peeling as many types of polymer compounds as possible and capable of reducing a burden required for a peeling treatment when a polymer compound having adhered to an adhesion object is peeled. The polymer compound peeling agent for peeling a polymer compound having adhered to an adhesion object contains a photoresponsive liquid crystal material having a phase structure reversibly transitioning between an isotropic phase and a liquid crystal phase due to photoisomerization based on irradiation lights of different wavelengths. When the polymer compound is adhered to the adhesion object, the photoresponsive liquid crystal material is contained in the polymer compound with the phase structure set to the isotropic phase, and the phase structure of the photoresponsive liquid crystal material is allowed to transition from the isotropic phase to the liquid crystal phase by photoisomerization based on the light irradiation.
