Abstract
The utility model provides a photometric angle appearance, including the mounting box that is used for holding photometric angle device, the light inlet hole department of mounting box top is provided with printing opacity filter cover. Through adding printing opacity filter cover in the above-mentioned scheme can effectively prevent external environment to the influence of photometry angle device.
Description
Technical Field
The utility model relates to an optical measurement field specifically is exactly a photometry angle appearance.
Background
Solar cell panel carries out sufficient sunshine for guaranteeing to shine, generally need carry out along with the light angle modulation to keep solar cell panel face perpendicular with light, however this regulation easily appears the deviation among the actual operation process, influences the generating efficiency, consequently needs the photometry angle appearance to measure light and solar cell panel direction, in order to learn this deviation.
The photometry angle appearance among the prior art structure is complicated, thereby it knows the light angle according to the mirror surface angle in mainly reflecting light to specific aperture through the adjustment mirror surface angle again, and this kind of structure precision requires highly, and the structure is complicated to be installed and is very fragile in outdoor environment. And because solar cell panel generally places under the highlight external environment, to light too strong generally can cause certain damage to the photometer, perhaps appear measuring inaccurate phenomenon.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a photometric angle appearance can measure light and ground or mounted position's contained angle to the protection appearance does not receive the highlight to influence.
In order to achieve the above purpose, the technical scheme of the utility model is that: a light angle measuring instrument comprises a mounting box for accommodating a light angle measuring device, wherein a light transmitting and filtering cover is arranged at a light inlet hole above the mounting box.
Through adding printing opacity filter cover in the above-mentioned scheme can effectively prevent external environment to the influence of photometry angle device.

Detailed Description
A light angle measuring instrument comprises a mounting box 70 for accommodating a light angle measuring device, wherein a light-transmitting filter cover 80 is arranged at a light inlet hole above the mounting box 70. Prevent external rainwater dust and photometry angle device contact through adding printing opacity filter cover 80 in the above-mentioned scheme, reduce the light intensity through filtering simultaneously, prevent too high light intensity influence sensor precision.
The goniometer means comprises light intensity sensors 10 evenly spaced along an arc. The light intensity collected by the light intensity sensors 10 on the arc-shaped light source is different due to the reason of arc arrangement, the point where the light intensity sensor 10 at the highest light intensity position is located can be judged as a light direct-emitting point in the arc-shaped span direction, the perpendicular direction of the light intensity sensor 10 and the arc-shaped curvature axis core can be regarded as the projection direction of the light direction on the arc-shaped 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: the photometric angle device includes first arc 20, and 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.
The light angle measuring device comprises a second arc-shaped plate 30, light intensity sensors 10 are uniformly arranged on the outer plate surface of the second arc-shaped plate 30 at intervals, the curvature axis core of the second arc-shaped plate 30 is perpendicular to the curvature axis core of the first arc-shaped plate 20, and the tops of the first arc-shaped plate 20 and the second arc-shaped plate 30 are overlapped. 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: the light angle measuring device 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.
The goniometer assembly further comprises a flex cable 50 for connecting the wires and a connecting rod 60 for connecting the mounting box 70. Connection and wiring are facilitated.
The light-transmitting filter cover 80 is a cylinder shape protruding out of the surface of the box body, and the photometric angle device is arranged in the cylinder shape. So that light entering in multiple directions can be better measured for light angle.
The light-transmitting filter cover 80 is made of color-changing glass. So that it can still perform photometry in a low light environment.
