Problems solved by technology

[0009] In addition, the patient needs to maintain a long-term motionless posture while constraining the body for treatment, which puts an excessive load on the body and feels fatigue
Moreover, when the affected part has a curved surface, such as a part of an arm or a part of a foot, any of the front side, rear side, or side of the part can be treated with a device using a lamp-type light source. Partially irradiated, forcing the patient into unreasonable positions
[0010] In addition, depending on the angle and distance of the affected part having a curved surface from the device using the lamp-type light source, the irradiation intensity varies for each part constituting the affected part, so it may be difficult to uniformly irradiate the affected part as a whole. The intensity of the treatment light in the case of the irradiation
In addition, a device using a lamp-type light source requires a large space for installation and is also expensive due to the large number of accessories such as a power supply and a cooling device.

[0058] based on Figure 1 to Figure 5 , Figure 17 to Figure 20 One embodiment of the present invention will be described as follows. Hereinafter, the LED chip 14 mounted in the light irradiation module 2 (light source: refer to Figure 17 ) as the front surface, and the surface opposite to the surface on which the LED chip 14 is mounted is the back surface.

[0059] In addition, if Figure 17 As shown, in the flexible substrate 15 (substrate), a plurality of LED mounting regions 17 on which the LED chips 14 are mounted are formed in a lattice shape in plan view. Two adjacent LED mounting regions 17 are insulated, and the two LED mounting regions 17 are connected by wiring 16 . In addition, wire bonding connections are also included in the wiring 16 .

[0060] Here, use Figure 18 The positions of the light shielding member 3 and the LED chip 14 in the phototherapy device 1 (photoirradiator) according to the first embodiment of the present invention will be described. S...

Abstract

The objective of the present invention is to carry out radiation of light onto a desired region of the skin reliably and simply, while preventing radiation of light onto regions other than the desiredregion. A light radiator (1) is provided with: a light source which radiates light onto skin; a light shielding member (3) disposed between the skin and the light source; and a flexible base on whichthe light source and the light shielding member (3) are mounted; wherein an opening portion (9) corresponding to a specific region (8) of the skin can be formed in the light shielding member (3), andlight is radiated onto the specific region through the opening portion (9).

Description

technical field [0001] The present invention relates to a photoirradiator and a photoshielding member used for photoirradiation therapy, beauty and hairdressing, and the like. Background technique [0002] Photodynamic therapy (Photo Dynamic Therapy; PDT) is a chemical reaction caused by irradiating light of a specific wavelength to a photosensitive substance that has an affinity for abnormal cells and tumors to generate active oxygen, etc. Treatment of tumor necrosis. Starting from a therapeutic method that does not damage normal cells, the viewpoint of QOL (Quality Of Life) has recently attracted much attention. [0003] PDT is used for various purposes such as treatment of diseases such as neonatal jaundice, psoriasis, and acne, pain relief, and beauty and hairdressing. Acne treatments use blue, red, and yellow lights. In this way, when performing PDT, a light source that irradiates light of an appropriate wavelength is used depending on the purpose of treatment.
