Description

Phototherapy beauty device

The invention relates to a phototherapy skin-care device, in particular to a phototherapy skin device which utilizes light waves of a special color and wavelength of a light-emitting diode (LED) and a light wave of a far-infrared diode to achieve a skin-beautifying effect.

Phototherapy improves the skin and beauty effects, and has recently been proven to be innovative and effective therapies, such as <Taiwan Medical Journal> (2011/03), Vol.54, NO.3, Guo Xudong, Chen Yucheng, and Zhang Tianchang. The general situation and progress of phototherapy in dermatology, detailing the principles and effects of related phototherapy. Also, <Beauty Science and Technology Journal> 9 Volume 1 "Impact of phototherapy exposure on human skin texture", author Li Yipin and Zhuang Yukai mentioned: The experimental results found that 1. After the red light is irradiated to the skin, it is obvious every week. Brightening skin tone and fine skin texture, the most significant and sustained effect with red light around 630nm. 2. After the yellow light is irradiated to the skin, it is best to illuminate the skin for the second week. 3. After the green light is applied to the skin, the skin becomes finer after the second week. In addition, according to the "Investigative Dermatology" of the "Secondary Red Light on Skin" study, it is confirmed that red light of a specific wavelength can enter the dermis to stimulate fibroblasts and promote collagen proliferation. Reduces fine lines, makes skin more elastic, and achieves anti-aging Effect.

However, the medical-grade phototherapy skin-care device of the prior art is too bulky, and its unit price is very expensive, which is not available for general consumers to purchase, and consumer phototherapy devices such as the Republic of China announcements M436466, M256190, and M400317, which usually have The light-emitting module, the control module and the power module formed by the light-emitting diode (LED) are powered by the power module to the light-emitting module and the control module, so that the light-emitting module can emit specific wavelengths such as red light and yellow light. Light. However, the design of the conventional consumer phototherapy device still has some shortcomings. For example, the conventional phototherapy device directly uses AC power as the power source, or the external transformer must be used to continuously supply the DC power source, so that the user cannot leave the power line during use, and does not have the reverse charging function. You cannot use USB for charging, etc. In addition, the light-emitting diodes (LEDs) of the conventional consumer phototherapy device have too many current loops in parallel, so that they consume more power during operation, and thus it is not easy to adopt a battery-powered method (the power is quickly exhausted) and leads to The board has a working temperature that is too high. Moreover, the light-emitting area of the consumer phototherapy device is limited. If far-infrared, red, yellow/blue and green LEDs are to be implemented at the same time, it is necessary to reduce the number of LEDs of each color in order to be squeezed into the same phototherapy device, but this will result in various colors. The illumination surface is not uniform enough to achieve the desired effect.
