Detailed Description

A photometric angle device includes light intensity sensors 10 arranged at regular intervals along an arc.

In the above scheme, the light intensity collected by the light intensity sensor 10 is different due to the reason of the arc arrangement, the point where the light intensity sensor 10 at the highest light intensity position is located can be judged as the light direct-emitting point in the arc span direction, the perpendicular direction of the light intensity sensor 10 and the arc curvature axis core can be regarded as the projection direction of the light direction on the arc radial surface, and the light direction can be known according to the preset angle value corresponding to the light intensity sensor 10. Thereby realize the measurement of light direction, can set firmly this device on the solar cell panel face and rotate along with it to solar cell panel.

The first embodiment is as follows: including first arc 20, even interval arrangement has light intensity sensor 10 on the outer face of first arc 20. The arc-shaped plate is simple in structure and convenient to arrange.

Including second arc 30, even interval arrangement has light intensity sensor 10 on the outer face of second arc 30, and the camber axle core of second arc 30 is perpendicular with the camber axle core of first arc 20, the top coincide of first arc 20 and second arc 30. This allows the measurement of the X-plane and Y-plane ray projections, which are the radial planes of the first arc 20 and the second arc 30, respectively, to determine the three-dimensional direction of the ray. When the device is fixedly arranged on a solar cell panel, the curvature axis core intersection point connecting line of the light intensity sensor 10 at the top superposition position and the two arc plates can be set to be perpendicular to the surface of the solar cell panel, so that when the light intensity of the light intensity sensor 10 is the highest, the sunlight can be judged to be right opposite to the solar cell panel.

Example two: comprises a hemisphere 40, and light intensity sensors 10 are densely distributed on the outer surface of the hemisphere 40. Thus, the direction of the line connecting the light intensity sensor 10 with the center of curvature of the hemisphere 40 at the position of highest light intensity is the light direction. Then, the light direction can be known according to the preset angle value corresponding to the light intensity sensor 10.

Also included are flex 50 for connecting the wires and tie bars 60 for mounting. Connection and wiring are facilitated.
