Energy-saving light curing device

The present invention relates to a light curing device, and more particularly to a light curing device having an energy saving effect.

Beauty is a woman's nature. In particular, women will apply resin paint on finger or fingernail nails or retouch various styles of small ornaments to increase the aesthetics of nails. The resin coating applied to the nail on the market can be classified into a photocurable type and a solvent type. Since the solvent type contains a chemical solvent and volatilizes during use, which affects the health of the user, it has recently become a photocurable resin coating. Thus, when performing nail painting, it is necessary to use a photocuring device to cure the resin coating.

Referring to FIG. 1 , a conventional light curing device includes a housing body 11 , a socket 12 disposed in the housing body 11 and electrically connected to a lamp 120 , and a circuit control device 13 . The housing body 11 includes a receiving slot 111. The lamp holder 12 is disposed horizontally above the receiving slot 111. When the user places the resin coated finger 10 into the slot 111, After the light source generated by the lamp 120 is irradiated, the purpose of curing the resin paint is achieved.

The lamp 120 used in the light curing device can be a lamp tube (as shown in the figure) 1) and the Light Emitting Diode (LED) module (shown in Figure 2). Among them, the large volume of the lamp tube and the energy consumption and the light-emitting band include the risk that the UVA, UVB, and UVC are carcinogenic to the human body, but the LED is small in size, and is more energy-saving and avoids the harmful band of the human body, and Arbitrarily arranged to combine the desired shape of the illuminated area. Therefore, the LED module gradually replaces the lamp tube and becomes the lamp 120 mainly used in the current photocuring device.

Referring to FIG. 3 and FIG. 4, since the LED has an exit angle and the light intensity is inversely proportional to the square of the illumination distance, if the LED module is too far away from the nail portion to be irradiated, the LED module is irradiated to the nail. The light intensity is too weak (as shown in FIG. 3), and the arrangement density of the LEDs of the LED module needs to be increased to achieve the intensity of the illumination light required for curing the photocurable resin applied to the nail. Conversely, if the LED module is too close to the nail portion to be irradiated, the LED has a limited range of light emission when it reaches the nail portion, and many light irradiation corners are generated, thereby causing the photocuring resin on the nail to be cured to a different degree (as shown in the figure). 4)), therefore, it is also necessary to increase the arrangement density of the LEDs of the LED module to reduce the occurrence of dead spots of light shining on the nail.

Therefore, how to obtain a suitable height of the LED module, so that the LED arrangement density is reduced, the number of LEDs can be reduced, and the overall energy consumption can be reduced, and at the same time, the intensity of the illumination light required for curing the photocurable resin is The problem to be solved.

Therefore, the object of the present invention is to provide a light curing device which is optimized in arrangement of LED modules and has an energy saving effect.

Therefore, the novel light-curing device with energy-saving effect comprises a copy Body unit, and a light curing unit.

The body unit can be disposed on a plane and includes a top plate, and two side plates respectively extending outward from the left and right sides of the top plate. The top plate has a bottom surface that is opposite and parallel to the plane, and the distance between the bottom surface and the plane is between 33 mm and 45 mm.

The photocuring unit includes a plurality of light emitting diodes which are surface mount devices. The light emitting diodes are spaced apart from the bottom surface of the top plate and can emit light when powered. The light-emitting diodes have a wavelength between 400 nm and 410 nm and an exit angle of between 110 and 130 degrees.

Preferably, the number of the light emitting diodes disposed on the bottom surface of the top plate is twenty-four.

Preferably, the side panels each have a swash plate portion adjacent to the top plate and a support plate portion. The distance between the support plate portion and the corresponding swash plate portion and the plane is between 15 mm and 25 mm.

Preferably, the photocuring unit further includes a plurality of light emitting diodes disposed at a distance from each other on the bottom surface of the swash plate portion. The number of the light-emitting diodes of each swash plate portion is nine.

Preferably, the light emitting diodes have a wavelength between 400 nm and 410 nm.

The effect of the novel is to reduce the LED array density by appropriately setting the height of the LED, and to reduce the amount of LED used, and to reduce the overall energy consumption, and at the same time achieve the illumination light required for curing the photocurable resin. strength.
