The utility model provides a kind of light angle sensor; Wherein, be provided with first photographic plate, second photographic plate, the 3rd photographic plate, the 4th photographic plate in the transparent body, the top, center of first photographic plate, second photographic plate, the 3rd photographic plate, the 4th photographic plate correspondence is provided with shadow shield; First photographic plate and second photographic plate be one group and about corresponding; The 3rd photographic plate and the 4th photographic plate are another group and front and back are corresponding, when light source is rake angle, through the shading of shadow shield; First photographic plate produces different current signals with second photographic plate; The 3rd photographic plate also produces different current signals with the 4th photographic plate, and when light source was center position, first photographic plate, second photographic plate, the 3rd photographic plate, the 4th photographic plate then produced identical current signal.

In above-mentioned light angle sensor, preferably, this first photographic plate, second photographic plate, the 3rd photographic plate, the 4th photographic plate are designed to rake angle.Perhaps preferably, this transparent body surface design becomes circular arc planar.

The utility model provides a kind of light angle sensor, wherein, is provided with first photographic plate, second photographic plate in the transparent body; Corresponding about first photographic plate, second photographic plate are, its top, corresponding center is provided with shadow shield, when light source is rake angle; Shading through shadow shield; First photographic plate produces different current signals with second photographic plate, and when light source was center position, first photographic plate then produced identical current signal with second photographic plate.

Below in conjunction with said structure, the useful technique effect of the utility model is described:

One of which is located at the multi-disc photographic plate in one transparent body, reaches that the location is firm, volume is little, and obtains cheap, the convenient effect of using.

Its two, the photographic plate in the transparent body is designed to four photographic plates, a shadow shield, four photographic plates be designed to two corresponding each other, and form two groups, can sensing X axle, the light of Y axle, and obtain the accurate effect of 360 degree sensitization.

Its three, shadow shield is located at four rake angle photographic plates top, when light is the rake angle irradiation, can produces the different effect of light intensity of two photographic plates fast, and then the effect of accurate Calculation light angle is provided.

[main element symbol description]

10 transparent bodies, 15 shadow shields

11 first photographic plate L light sources

12 second photographic plate θ shading angles

13 the 3rd photographic plates

14 the 4th photographic plates.

Embodiment

See also Fig. 1 to Fig. 6; Be be provided with in the transparent body 10 first photographic plate 11, second photographic plate 12, the 3rd photographic plate 13, the 4th photographic plate 14, first to fourth

photographic plates

11,12,13,14 corresponding tops, center be provided with shadow shield 15, the first photographic plates 11 and second photographic plate 12 be one group and about corresponding; The 3rd photographic plate 13 be another group with the 4th photographic plate 14 and front and back corresponding; Again, first to fourth

photographic plate

11,12,13,14 is designed to rake angle, is the state to declivity; First to fourth

photographic plate

11,12,13,14 can produce electric current in receiving the light time, and the transparent body 10 is designed to the surface and is circular-arc, and the transparent body 10 is solid, coats first, second, third and fourth photographic plate of location and shadow shield 15.

Through above-mentioned structure; Can obtain following effect, advantage:, corresponding about first and second

photographic plate

11,12 is like Fig. 3 to shown in Figure 5, thus the light sensing of formation X axle; It is corresponding before and after third and fourth

photographic plate

13,14 is; Therefore form the light sensing of Y axle, X axle, Y axle light sensing can form comprehensive light sensing angle of 360 degree.When light source L was upper left side shown in Figure 6, second photographic plate 12 received irradiate light comprehensively, and first photographic plate 11 then receives the shading of shadow shield 15; The area light that has a shading angle θ a little less than; In other words, the inevitable electric current of the electric current that second photographic plate 12 produces greater than 11 generations of first photographic plate, this two current signal is connected to controller; The comparison of logic IC circuit in the via controller, the angle that can predict light source L is to 12 skews of second photographic plate.As shown in Figure 7, when light source L was to shadow shield 15, first and second

photographic plate

11,12 did not all receive shading, and the electric current that first and second

photographic plate

11,12 produces is identical.As shown in Figure 8, as light source L during to the upper right side, first photographic plate 11 receives irradiate light comprehensively, and 12 of second photographic plates receive shadow shield 15 shadings, and therefore, the electric current that first photographic plate 11 produces is greater than second photographic plate 12.In like manner, third and fourth

photographic plate

13,14 also can receive the effect of shadow shield 15 shadings just like first and second

photographic plate

11,12, and is able to form the signal of different electric currents, and not shading then is the same current signal during middle position; Can be known that by above-mentioned explanation first and

second shadow shield

11,12 can produce the effect of X axle light sensing angle, third and

fourth shadow shield

13,14 can produce Y axle light sensing angle, thereby can form 360 degree detecting light source L angle position comprehensively.

Above-mentioned sensing signal can be connected to controller, and controller then connects the motor of solar panels pedestal, and be able to control the motor action pedestal is adjusted according to light-source angle; And then make the solar panels on the pedestal keep best angle to bear light.

Again, the said structure of the utility model also has following effect, advantage:

(1) four photographic plates, a shadow shield are all finalized the design in the transparent body 10, and obtain firm, the moistureproof effect that reaches anti-adverse environment in location, and be convenient for carrying.

(2) it is circular-arc that the transparent body 10 is designed to the surface, is the convex lens kenel, and obtain spotlight effect, can obtain to promote the effect of ray cast in first, second, third and fourth

photographic plate

11,12,13,14 intensity.

(3) first, second, third and fourth

photographic plate

11,12,13,14 is designed to rake angle, and can obtain the preferable effect of accepting the rake angle light source.

(4) first, second, third and fourth

photographic plate

11,12,13,14, shadow shield 15, and the transparent body 10; Can be designed to small size, small size; And, also can be designed to large tracts of land, big volume applicable to small-sized portable solar electric organ, and applicable to large-sized solar plate power generation and heat collection equipment.

When (5) installing, only need the transparent body 10 is put due to desired location, it is extremely convenient to use.

In addition; According to above-mentioned technological means; The utility model also can implement to be the form of Fig. 9, Figure 10, for: only establish first and second

photographic plate

11,12 in the transparent body 10, reach shadow shield 15, form the light sensing angle of single axle; Obtain diaxon light sensing angle, then use two Fig. 9, structure shown in Figure 10.
