Laser treatment is well-known in various treatments using light, but the present invention adds the spatial coherence characteristics of a laser to an incoherence LED and uses low directivity as it is. Therefore, it becomes a light health appliance with low response level.
The present inventor previously performed a treatment applying a reversible photobiological activation reaction within the range of cell survival in the laser treatment, as a low response level laser treatment (LLLT) and a low response level laser treatment (LLLT). Although it is named and is now an international idiom, this concept can also be used for biological reactions other than photothermal reactions (photoelectromagnetic reaction, light pressure reaction, photochemical reaction, etc.). The effects of low response level laser treatment (LLLT) using the above laser light include anti-inflammatory effect, removal of edema, improvement of blood circulation, pain relief, improvement of collagen disease, improvement of skin ulcer, softening / flattening of scars Effects such as conversion are known.
Further, in the case of laser light, safety management is necessary due to its characteristics, and handling is limited and is often limited to doctors and medical institutions, but in the case of LED, handling is simple.

The same effect can be obtained as a therapeutic effect by light emission of the light emitting diode. However, in the case of non-polarized light by a simple light emitting diode, the light form is different from that of the laser light, and thus the low response level phototherapy. The effect of was small.
However, the present inventor has found that the effect of the low response level light treatment is improved by arranging and irradiating a linear polarizer on the optical path surface of the light emitting diode. Unlike the non-polarized light, the linearly polarized light vibrates in the same plane as the traveling direction. Therefore, the linearly polarized light becomes a transverse wave aligned in one direction, for example, a straight line of an external mirror laser having a Brewster window. It is thought that it acts on the living body similar to polarized light.
Further, for example, the right-circularly polarized light by the right-circular polarizing plate having the fast direction in the y direction out of the neutral axes x and y of the quarter-wave plate forming 45 ° with respect to the transmission axis of the linear polarizing plate is the same. Furthermore, it has been found that the effect of the low response level phototherapy is improved.

In addition, by selecting light with a very narrow half-value width (preferably 4% or less) from the emission spectrum of the LED, it becomes possible to approach monochromatic light having a specific wavelength. As a means for this, a linear polarizer or a right circular polarizer and a pan-pass filter are disposed in combination on the radiation surface of the LED.
In addition, the combination order of the said polarizer and a band pass filter may arrange | position both of them close to the radiation | emission surface side of LED.
Due to the above, for example, ultraviolet light, visible light, and infrared light having different wavelength ranges have different degrees of penetration into the living body, and have different effects on specific cells among various constituent cells of the living body. As shown in the above, a comprehensive therapeutic effect can be obtained by selecting monochromatic light suitable for the symptoms.

As the shape of the present treatment device, it is desirable to have a flexible surface that can use the power of the light-emitting diode as effectively as possible and can approach or abut against any part of the living body. In this example, a plurality of light emitting diodes are arranged on a flexible substrate, and the polarizer uses a flexible film material.
Alternatively, the light-emitting diode alone may include an optical element such as a polarizer and a bandpass filter, and a flexible surface may be configured as a composite.
The structure will be described below with reference to the drawings.
