Ultraviolet phototherapy device is a series A desktop device among ultraviolet phototherapy products, which uses ultraviolet light source and is mainly used by medical institutions to treat skin diseases such as vitiligo, psoriasis, and hand eczema.
Product Features
The light source spectrum is pure, the treatment efficiency is high, and the side effects are small
The irradiator equipped with the irradiation light source can move up and down and rotate freely to adapt to the needs of irradiating various parts of the body.
Equipped with a digital timing system, the irradiation time can be set according to the patient's condition and suitable light sensitivity
It has alarm and beep/stop selection functions. If you select "Stop", the buzzer will sound when the irradiation ends to remind the patient or medical staff that the operation is completed. However, if you do not turn off the light, if you select "Stop", the light source will automatically turn off when the irradiation ends.
It is light in size, easy to operate, stable and reliable in operation, and can be used alone or as a supplementary irradiation after irradiation with other types of phototherapy devices.

Ultraviolet Phototherapy What is the warranty scope and period of the instrument?
Our company is responsible for the warranty of the phototherapy instrument for one year from the date of delivery. Except for the consumable parts of the product (light tube) or faults caused by improper use, the company provides free maintenance services during the warranty period. After the warranty period expires, our company will continue to provide paid maintenance services.
Plastic parts will yellow due to exposure to ultraviolet radiation, which is normal and is not covered by the warranty.
The product I purchased is faulty, how can I repair it?
Call the customer service department of Shanghai Sigma High-Tech Co., Ltd. and mail the product back to the Shanghai factory.
How to perform daily care and maintenance of ultraviolet phototherapy equipment?
The phototherapy device should be placed in a dry room to avoid direct sunlight.
For the needs of treatment, the working environment temperature of the phototherapy device is ℃℃. Environmental temperatures that are too high or too low may cause the phototherapy device to work abnormally and affect the treatment effect.
Keep the surface of the phototherapy device and the transparent plate of the illumination window clean. Do not leave fingerprints on the surface of the transparent plate of the illumination window, otherwise it will affect the radiation intensity of the illumination.
The phototherapy device is afraid of moisture and dust. If it is not used for a long time, please clean it and put it in the box. Store it in a place with a temperature of ℃ ~ + ℃, a relative humidity of no greater than 100, no condensation water, no corrosive gases, and a well-ventilated place. indoor.

The basic concept of light
Light is a substance with dual properties of electromagnetic wave and particle flow. In other words, light has not only electromagnetic wave characteristics such as wavelength, frequency, reflection, refraction, and interference, but also quantum characteristics such as energy, absorption, photoelectric effect, and light pressure. Therefore, all physical phenomena of light and the therapeutic effects of light are either related to its wave properties or to its particle properties.
Light is an electromagnetic field that can propagate as waves in vacuum and media and is composed of vibrating electric and magnetic components. As a wave, light is an electromagnetic wave, in which the propagation directions of electric fields, magnetic fields and light are perpendicular to each other. At the same time, light can be distinguished by wavelength (wavelength is the distance between two consecutive peaks and exhibits interference and diffraction phenomena between electromagnetic waves.
The distribution of a series of electromagnetic waves (a function of wavelength, frequency or wave number ) is defined as the electromagnetic spectrum. Different wavelength regions are often given a special name. For example, the long wavelength end of the spectrum is called radio frequency. Arranging the light according to the wavelength of various lights is called a spectrum. From far infrared to vacuum ultraviolet The spectral range is called the optical frequency domain ( ).
