Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of light angular sensor.
Background technology
The sun is the precious resources that the mankind can infinitely utilize.Along with development of science and technology, the utilization of sun power is deepened day by day.But the light of sun emission is angled, and angle is constantly to change, and this just need consider the variation of light angle when utilizing sun power, so that the raising of the utilization ratio of sun power.Therefore, the someone has invented the light angle sensing that cooperates solar energy equipment to use, but the common complex structure of these light angular sensors, costly.Also do not have on the market now a kind of simple in structure, expense is cheap and light angular sensor with good accuracy.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure, expense is cheap and precision is good light angular sensor.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of light angular sensor comprises a lighttight hemispherical shell that is surrounded by semisphere face and circular flat, and the symmetrical shaft core position of this hemispherical shell has a light hole, and the semisphere face inside surface of hemispherical shell is densely covered with light activated element.
Reflect, make the light angle and the external world that enter in the hemispherical shell to be consistent for fear of the light that enters hemispherical shell inside, described light hole is provided with light transmission piece, is evacuated in the described hemispherical shell.
In order to guarantee the accurate of light angular sensor light sensing angle, the size of described light hole is to be enough to make the light that is irradiated into to cover two spaces between the light activated element, can not produce scattering again.
In order to protect the light transmission of light transmission piece when not using, described hemispherical shell is outside equipped with protective cover.
Adopt technique scheme, when light is injected from light hole, the angle that the light of injecting is injected along light directly is mapped on the light activated element corresponding with this direction, this light activated element senses light signal then, this light signal is passed to and the matching used calculation element of light angular sensor, go out the angle that light is injected in the position calculation of the inside surface of the sphere of hemispherical shell according to this light activated element.Therefore, the present invention is simple in structure, expense ground amount, has the advantage that accurately senses light angle.

Embodiment
As shown in Figure 1, light angular sensor 100 of the present invention comprises lighttight hemispherical shell 1, and this hemispherical shell 1 is centered on by semisphere face 11 and circular flat 12 and forms.At circular flat 12 centers, promptly the symmetrical shaft core position of half shape housing 1 has a light hole 13, the inside surface of semisphere sphere 11 is densely covered with light activated element 14, and described light activated element 14 can adopt photodiode or phototriode or other light activated element.
Reflect, make the light angle that enters in the hemispherical shell to be consistent with the external world as far as possible for fear of the light that enters hemispherical shell 1 inside, described light hole 11 is provided with light transmission piece 15, is evacuated in the hemispherical shell 1.
In order to guarantee the accurate of light angular sensor light sensing angle, the size of described light hole 11 is to be enough to make the light that is irradiated into to cover two spaces between the light activated element 14, can not produce scattering again.
In order when not using, to protect the light transmission of light transmission piece, be provided with protective cover outside the described hemispherical shell 1, be that the light hole place is provided with protective cover 16 at least.
As shown in Figure 2, the principle of work of light angular sensor of the present invention is such:
When light enters when shining on the sphere 1 A from light hole 11, the distance from this A of vertical view to the hemisphere axle center is ρ, true origin O to the line of this point on the xOy plane projection and the angle of x axle be
The radius of hemisphere is r, this sunray and x axle so, y axle, z axle angle theta
x, θ
y, θ
zCosine be respectively:
By above-mentioned formula, just can calculate light angle.
As shown in Figure 3, the use-pattern of light angular sensor of the present invention is as follows:
Light angular sensor 100 is vertically placed, the circular flat 12 that is about to the hemispherical shell 1 of light sensor keeps vertically, can adjust angular transducer 100 vertically in conjunction with level meter 200 and plumb aligner 300 by setting nut 400 adjusting maintenances, allow light inject in the hemispherical shell 1 of light angular sensor 100 from light hole 11, be radiated on certain light activated element 14, this light activated element 14 just can have the heavy electric signal of accepting of light signal conversion to cooperate the calculation element of light angular sensor to calculate light angle.If when the light activated element of a slice responds simultaneously, that in the middle of getting is as angle orientation.
By foregoing description as can be seen, the present invention is simple in structure, and expense is cheap, has the advantage that accurately senses light angle.
It more than is exactly light angular sensor of the present invention, but, one skilled in the art would recognize that above-mentioned embodiment is exemplary, be to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
