Multifunctional phototherapy device with switchable wavelength

1. Technical field

The invention relates to a phototherapy device, in particular to a multifunctional phototherapy device capable of switching different irradiation wavelengths according to different needs, and having uniformly distributed irradiation areas and reducing the switchable wavelengths caused by irradiation dead angles.

2. Background technology

With the change of people's life style, people often have various lesions on the skin due to factors such as work pressure or eating habits. Therefore, in recent years, pulsed light (Intense Pulsed Light, IPL) has been used to treat various skin diseases. Has become a trend.

The research on pulsed light began in 1990, and its spectrum of action is quite broad, about 550 to 1200nm wavelength light, including visible light and infrared range, pulsed light has high energy and wavelength of laser, due to the absorption and scattering of different light waves by skin tissue With various reactions, the pulsed light system can select the corresponding light wave to deal with various skin problems, for example: yellow to orange light will act on the red blood vessels on the skin, and red light can be used for pigment removal.

Due to the above characteristics, pulsed light can choose the appropriate wavelength to treat various skin problems, such as vasodilation (reduction of redness), pigmentation problems (depigmentation) and stimulation of fibroblasts in the dermis (rejuvenation), etc. In addition, such as: spots, uneven pigmentation, dilation of blood vessels, redness of the face, roughness and inelasticity, there are also quite satisfactory results.

However, pulsed light instruments are expensive and require high technical requirements for instrument operation, so they cannot be used by ordinary small clinics or families. For this reason, a small and portable phototherapy device was developed accordingly.

As shown in Figure 1, it is a schematic structural diagram of an existing phototherapy device, which is provided with an irradiation head 12 on the body 11, and several light-emitting diodes (LEDs) 13 of predetermined wavelengths are installed on the irradiation head 12, and can be used manually.

The irradiation head 30 has a light-transmitting cover 31, and the light-transmitting cover 31 can be installed from the inside to the outside of the irradiation head 30, but it is not limited thereto, that is, it can be nested in the irradiation head 30 from the outside, or the light-transmitting cover 31 can be nested in the irradiation head 30 by using high frequency and other processing methods to make it fixed on the irradiation head 30, so it will not be described in detail.

A plurality of LEDs 40 are electrically connected to a circuit substrate 50 , and the circuit substrate 50 is sleeved in the irradiation head 30 , which enables the LEDs 40 to emit light toward the transparent cover 31 .

One of the main features of the present invention is that the irradiating head 30 and the transparent cover 31 are not circular with products, but are made into rectangular bodies. Of course, the four corners of the rectangular body can be slightly arc-shaped, but not It is limited to this, and the design of the rectangular body is to eliminate the problem of the blind spot 14 shown in FIG.

In consideration of the area and circuit layout of the circuit substrate 50 , it is preferable to use light emitting diodes 40 a , 40 b , and 40 c with three different wavelengths during implementation, but it is not limited thereto. As for the staggered arrangement of light emitting diodes with different wavelengths, it can be arranged individually or in a row. In principle, it is better to strive for uniform illumination of each wavelength of light emitting diodes.

As shown in FIG. 7 , a feasible embodiment of the illumination light source of the present invention is that the light-emitting diode 40 is pre-packaged with the LED chip 41 by the light-transmitting colloid 42, and then electrically connected to the circuit board 50 by its pin 43. .
