Embodiment
Embodiment one: shown in Fig. 1 ~ 3, a kind of nearly sphere sun angle detecting device, comprise the base 1 that two symmetrical intervals arrange, the end that two bases 1 are close all has a sphere breach 1-1, form the segment-shaped groove 2 of a nearly sphere between two sphere breach 1-1, the surface of described segment-shaped groove 2 is coated with the reflection horizon (not illustrating among the figure) of reflection ray, the top of two bases 1 is provided with cover plate 3, shown in cover plate 3 surfaces, all be adhesive with light-absorbing light absorbent layer (not illustrating among the figure) in the interval between segment-shaped groove 2 periphery and two bases 1, offer a diameter less than the printing opacity aperture 3-1 at interval between two bases 1 in the middle of the described cover plate 3, the lower of described printing opacity aperture 3-1 is the centre of sphere of nearly sphere along the center, being equipped with in the described printing opacity aperture 3-1 to make light see through and prevent the light transmission piece 4 that foreign material enter, the downside of described cover plate 3 is provided with photoelectric testing sensor 5 in the symmetria bilateralis of printing opacity aperture 3-1, distance between each photoelectric testing sensor 5 and the printing opacity aperture 3-1 center is the twice of two interval pitch between the base 1, and the interval between the line projection of two photoelectric testing sensors 5 and two bases 1 is perpendicular.
In the present embodiment one, described two photoelectric testing sensors 5 are any one two or any two kinds combination in photoresistance, photodiode, phototriode and the silicon photocell.Described base 1 can be to be made by metal, plastic or other material, and described metal can be simple metal or alloy, stainless steel for example, and described plastics can be ABS, PC or PET etc., the material of base 1 can also be pottery or wooden etc. certainly.Described light transmission piece 4 is transparent glass sheet, but is not limited to this, can also be the sheet material of being made by other transparent material, for example transparent resin sheet or plastic sheet.
In the present embodiment one, if the interval between two bases 1 is removed, two sphere breach 1-1 are with regard to the segment-shaped groove 2 of complete so, and the centre of sphere of described segment-shaped groove 2 is edge under the printing opacity aperture 3-1 in the middle of the cover plate 3; Because a very little interval is arranged between two bases 1, and the size at this interval compares little much with the centre of sphere radius of segment-shaped groove 2, therefore can regard segment-shaped groove 2 as nearly sphere.
In the present embodiment one, to be decided to be directions X perpendicular to the direction at interval between two bases 1, the direction that will be parallel to interval between two bases 1 is decided to be Y-direction, and the direction at interval between 3 to two bases 1 of cover plate is decided to be the Z positive dirction, true origin is fixed on the center of printing opacity aperture 3-1.
To be radiated in two intervals between the base 1 after the YZ plane sees through printing opacity aperture 3-1 according to the light of coming, light is absorbed by light absorbent and is not produced reflection.To incide the X negative direction and cast oblique rays on the light of coming from the X positive dirction through behind the aperture 3-1, on the close photoelectric testing sensor 5 of X negative direction one side on the reflection arrival cover plate 3 of segment-shaped groove 2 outermost reflectors.Because the reflection of segment-shaped groove 2 outermost reflectors, the setting sun is come as long as the light of incident is the X positive dirction, all can penetrate after its reflection on the close photoelectric testing sensor 5 of X negative direction one side on the cover plate 3, and is irrelevant with the numerical value of Y.Equally, cast oblique rays on the light of coming from the X negative direction and will incide the X positive dirction through behind the aperture 3-1, on the close photoelectric testing sensor 5 of X positive dirction one side on the reflection arrival cover plate 3 of segment-shaped groove 2 outermost reflectors.That is to say, can easily detect whether vertical incidence or be partial to which side of the sun with this nearly sphere sun angle detecting device,, all can impinge upon after the process reflection above in two very little photoelectric testing sensors 5 of area according to the light of coming so long as not the YZ plane.Therefore, whether it only detects has light to impinge upon above the photoelectric testing sensor 5, needn't carry out relative value relatively, it is the computing of digital quantity rather than analog quantity, therefore control circuit is very simple, and antijamming capability is also very high, and physical dimension also can do very little.
Embodiment two: in fact, the employing passive type detects for sun angle deviation size and does not require, as long as know angular deviation and the direction of the sun and lighting surface, just can progressively follow the tracks of the attitude of adjusting the solar cell plane skylight, therefore at the lighting surface of solar battery apparatus nearly sphere sun angle detecting device is installed and just can be reached preferably effect.As shown in Figure 4, a kind of solar battery apparatus, comprise plane skylight 6, a pair of orthogonal above-mentioned nearly sphere sun angle detecting device is installed on the lighting surface of described plane skylight 6, one of them nearly sphere sun angle detecting device is positioned on the limit of another nearly sphere sun angle detecting device.
In the present embodiment two, this solar battery apparatus can carry out the control of lighting surface twin shaft, detects the attitude that the sunray deviation just can be controlled the solar cell plane skylight according to nearly sphere sun angle detecting device.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
