PURPOSE:To always turn a mirror face to a direction for leading sun-light to a room side by providing the titled device with a control device for changing the direction of an automatic sun tracking sensor to a direction for equalizing the quantity of photodetection to plural optical sensors arranged on the mirror face side. CONSTITUTION:When the incident angle of sunlight to the automatic sun tracking type solar light collector 10 is changed and the quantity of photodetection to respective optical sensors in the automatic sun tracking sensor 29 is equalized, the control device 44 drives a driving means to change the direction of the sensor 29 to a direction for equalizing the quantity of photodetection to respective optical sensors and to move the mirror face to a direction for always leading the incident angle of solar light into the room side. Consequently, the quantity of light led into the room can be increased up to a state approximate to the direct radiation of solar light. |
