Preferably, the steam generating means 200 is located. More preferably, the back plate 114 is 80 to 100 cm in size, and the steam generating means 200 is more preferably 8 to 10 cm in size. In addition, the reflective plate 112 is coated with a material for reflecting the sunlight. Since the reflector 112 uses sunlight as a light source, it should always collect sunlight in an optimal state (the brightest state). Therefore, the bending degree of the reflector plate 112 should be changed according to the position of the steam generating means 200 and the focal length of sunlight. In the present invention, the screw 122 coupled to the outer center portion of the light collecting unit 110 and the screw 122 by rotating the motor 124 to deflect the light collecting unit 110 to adjust the orientation position to the optimal state.

The movement states of the incident light and the focused light are indicated by arrows in FIG. 4. The focusing of the sunlight as described above is to deliver in a concentrated state in a high energy state because the normal solar light has a low energy density and the illuminance is lowered when transmitted to a distant place.
