In another embodiment shown in FIG. 4, the phototherapy device 100 is a plurality of illumination modules 10 composed of an array of LEDs that are extended in one direction, such as in a lateral direction, to form an elongated treatment device. In this embodiment, the left and right side walls of each of the illumination module housings 11 are provided with openings, that is, the flat holes 12, and the upper and lower side walls are closed. Therefore, the flexible connector 20 is connected between the adjacent two illumination modules 10, and the outermost two illuminations are provided. The module 10 connects the external electrical connector 30 and the plug 50, respectively.

The flexible connector 20 used in Figures 1-4 above is shown in Figure 9. The phototherapy apparatus 100 of the third embodiment shown in FIG. 5 is a therapeutic apparatus in which a plurality of illumination modules 10 composed of an LED matrix are connected by using the flexible connector 20 of FIG. 10 to form an integral square array.

It will be appreciated that the outer shape of the illumination module 10 can be of various shapes that can be expanded around the outer casing in any direction including transverse and/or longitudinal and/or radial directions of radiation, by the flexible connector 20. A plurality of illumination modules 10 are coupled to form a treatment device of the desired area and size. The plurality of illumination modules 10 can be relatively bent.

It can be understood that the above-mentioned external connector 30 and the plug 50 are optional devices, and the side of the side wall of the casing that does not need to be expanded can be arranged in a closed type, and the plug 50 is just needed. If the illumination modules 10 are each powered or set up with a control program, the external connector 30 may not be used.

The term "plurality" as used in the present invention means "one or more" and includes "two."

While the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art The scope of the invention is defined by the appended claims and their equivalents.
