る。Therefore, when the cylindrical body 1 is facing the direction of the sun accurately, in other words, when the sunlight is coming from the direction A, the optical sensor
Direct sunlight (D) does not enter into 1 to X4, only indirect sunlight (1) enters, and direct sunlight (D) enters the optical sensor Xc.
D) and indirect sunlight (1) will be incident. However, if the cylindrical body 1 deviates from the direction of the sun, for example, the sunlight
If it is assumed that the light comes from the direction, the optical sensor
Therefore, the optical sensor X2 receives only indirect sunlight (I). To explain in more detail, when the cylinder 1 is exactly aligned with the direction of the sun, the optical sensors X1 and X2
(or X3 and
Since the sunlight incident on (or X3 and X4) is different, this difference is detected and the light sensor If the tube body 1 is controlled to face in the direction of the sun, the cylindrical body 1 will accurately face the direction of the sun, and therefore the sunlight collecting device equipped with the sunlight direction sensor will also face the direction of the sun accurately.

く適用可能であることは容易に理解できよう。FIG. 6 is a side sectional view for explaining one embodiment of the sunlight direction sensor according to the present invention. In the figure, parts having the same functions as those in FIGS. 1 to 4 are designated by the same reference numerals. It is attached. Therefore, in the present invention, a heat conductive material is used as the bottom plate 4, and a hole 5 is provided in the center thereof, that is, at a position corresponding to the window 3 of the top plate 2. The sensor Xc is mounted on a heat conductive insulating substrate 6, and the substrate 6 closes the hole at a predetermined distance from the bottom plate 4 so that the optical sensor Xc is inside the cylinder. Therefore, according to the present invention, the heat of the pigeon sensors X1 to X4 is not transferred to the optical sensor Xc, and on the contrary, the heat in the optical sensor Xc is easily radiated through the substrate 6 and the bottom plate 4. Therefore, the characteristics of the optical sensor It becomes possible to do so. In addition,
