The apparatus main body 2 includes a relatively large-diameter head 11 to which the cover 3 is attached and a grip portion 13 that extends from the head 11 through a constricted portion 12 so as to be easily grasped by a hand. . The apparatus body 2 has a predetermined length L (for example, 142 mm), a predetermined width W (for example, 45 mm), and a predetermined thickness T (for example, 32 mm).
[0020]
The apparatus main body 2 includes a main body case 2a to which the electric circuit board is fixed and a cover case 2b to which the cover 3 is attached. These cases 2a and 2b are made of, for example, plastic so as not to get tired even if they are held for a long time, and are closed spaces for accommodating the electric circuit and the LEDs by being detachably engaged so as to face each other. Form.

Further, the cover case 2b is provided with a switch 5 for turning on / off the light emission driving of the LED at a lower position of the cover 3, for example. For example, a heart-shaped mirror 5 and a connection terminal 6 are installed on the back surface of the main body case 2a. A connector of an adapter for supplying power to the electric circuit is electrically connected to the connection terminal 6.
[0022]
The translucent plate 4 provided on the cover 3 has complex irregularities on the surface in order to scatter light emitted from the LEDs. Further, the cover 3 is formed with a recess 9 by an annular tapered surface 3 a, and the translucent plate 4 is fitted in the recess 9. In this case, the tapered surface 3a is useful for directing scattered light emitted from the LED through the light transmitting plate 4 in a predetermined direction with a predetermined spread. The translucent plate 4 may be a polarizing plate that transmits only light in a predetermined direction.
[0023]
FIG. 4 shows a state where the cover 3 is removed from the apparatus main body 2. As illustrated, the cover case 2b of the apparatus main body 2 is formed with an opening 16 to which the cover 3 is detachably attached, and a plurality of light source modules 10 having a plurality of LEDs are positioned so as to face the opening 16. Has been. In the present embodiment, four light source modules 10 are arranged to face the opening 16. That is, in the state of FIG. 4 with the cover 3 removed, the four light source modules 10 are exposed through the openings 16.
[0024]
The four light source modules 10 have a circular shape and are mounted in a predetermined arrangement on a substrate 14 on which each element of the electric circuit is mounted. Specifically, in the present embodiment, the light source modules 10 are arranged one by one on the left, right, top and bottom so that each forms a rhombus apex. Note that, except for the light emitting surface of the light source module 10, the cover member 15 is substantially covered so that the electric circuit element is not exposed through the opening 16.
[0025]
As shown in FIG. 5, each light source module 10 has a plurality of LEDs. In the present embodiment, a total of ten LEDs 20 a to 20 d that emit light of two wavelengths or more are arranged in a predetermined arrangement in each light source module 10. Specifically, each light source module 10 includes two first LEDs 20a that emit red light having a wavelength of 644 nm, two second LEDs 20b that emit yellow light having a wavelength of 575 nm, and a near infrared wavelength having a wavelength of 940 nm. There are three third LEDs 20c that emit light and three fourth LEDs 20d that emit near-infrared light having a wavelength of 880 nm.
[0026]
Here, it is assumed that the circular region of the light source module 10 is divided into four regions A, B, C, and D by three boundary lines L1, L2, and L3 that are substantially parallel to a line segment that passes through the center of the light source module 10. In the first region A and the fourth region D on both sides, the first LED 20a and the second LED 20b are arranged in a line substantially parallel to the boundary lines L1, L2, and L3. In this case, in the first area A and the fourth area D, the order in which the first LEDs 20a and the second LEDs 20b are arranged is reversed.

They are arranged in a line. In this case, in the second region B, one fourth LED 20d is sandwiched between the two third LEDs 20c, 20c. Conversely, in the third region C, one third LED 20c is sandwiched between the two fourth LEDs 20d and 20d. That is, in the central regions B and C of the light source module 10, the third LED 20c and the fourth LED 20d are arranged in a staggered manner so that adjacent LEDs are not the same LED, and the regions A and D on both sides of the light source module 10 are arranged. Then, the first LED 20a and the second LED 20b are arranged in a row with the order in which they are arranged in reverse. That is, in the entire region of the light source module 10, an array form is formed such that adjacent LEDs are different LEDs.
