Below in conjunction with the drawings and specific embodiments, the present invention is elaborated further.
As shown in Figure 3, guiding device of the present invention comprises one-level rotary reflection assembly 13, secondary rotates reflection subassembly 14 and rotational control assemblies.Wherein, just for distinguishing two groups of rotary reflection assemblies, there is not the relation that sequencing rotates in firsts and seconds here.
Rotational control assemblies, rotate reflection subassembly 14 rotate around respective turning axle 10,11 for controlling one-level rotary reflection assembly 13 and secondary respectively, wherein both turning axles are mutually vertical, and intersect at joint, i.e. O point, one-level rotary reflection assembly 13 is arranged at secondary and rotates on reflection subassembly 14, and can rotate reflection subassembly 14 in company with secondary and together rotate.
Wherein, one-level rotary reflection assembly 13, is arranged on the one end near light source, after receiving incident beam 21 that light source sends, generates the first folded light beam 22.Secondary rotates reflection subassembly 14, and be arranged on the one end away from light source, after receiving the first folded light beam, generate final light beam 23, final light beam 23 and incident beam 21 are all perpendicular to the first folded light beam 22.
For convenience of description, face called after light vertically being entered this device here from the external world enters light face 9, and accordingly, light, from the face called after exiting surface 6 that this device internal vertical reflects away, enters light face 9 and exiting surface 6 is virtual reference plane.The light that light source passes through to enter into into light face 9 this device is called incident beam 21, and light reflects away from exiting surface 6, generates final light beam 23, i.e. final outgoing beam.
In optics, optical axis is defined as: the center line of light beam (light beam), or the axis of symmetry of optical system.Light beam rotates around this axle, the change of any optical characteristics that do not have.In the present embodiment, the optical axis P3 of the optical axis P1 of incident beam, the optical axis P2 of the first folded light beam and final light beam all through joint, i.e. O point.And the turning axle 10 of one-level rotary reflection assembly overlaps with the optical axis P2 of the first folded light beam, secondary rotates the turning axle 11 of reflection subassembly and overlaps with the optical axis P3 of final light beam.As seen in Figure 3, now one-level rotary reflection assembly 13 is positioned at joint place.

To achieve these goals, as shown in Figure 3, one-level rotary reflection assembly 13 comprises an one-level reflective mirror, for the ease of difference, is defined as the first one-level reflective mirror 1 in the application.First one-level reflective mirror 1 is in plane, and can be the level crossing being coated with reflectance coating, can be also optical total-reflection prism etc., its shape can be circle, square, rectangle, polygon or ellipse etc.In order to ensure the light that collection light source as much as possible sends, in the present embodiment, angle between first one-level reflective mirror 1 and the turning axle 10 of one-level rotary reflection assembly 13 is set to 45 degree by us, and turning axle 10 is through the geometric center of the first one-level reflective mirror 1.Incident beam, perpendicular to the first folded light beam, effectively can ensure projected area, gather light in a large number, makes light output quantity keep stable, can not affect the collection of light because of the change of incident angle.
Secondary rotates reflection subassembly 14 and comprises 2 secondary reflective mirrors, is defined as the first secondary reflective mirror 8 and the second secondary reflective mirror 7 in the application.First secondary reflective mirror 8 and the second secondary reflective mirror 7 can be the level crossings being coated with reflectance coating, and can be also optical total-reflection prism etc., its shape can be circle, square, rectangle, polygon or ellipse etc.Angle between first secondary reflective mirror 8 and the second secondary reflective mirror 7 is 45 degree, wherein, the minute surface of the first secondary reflective mirror 8 and the minute surface of the first one-level reflective mirror 1 are oppositely arranged, and the second secondary reflective mirror 7 is positioned at the below of the first one-level reflective mirror 1, the minute surface of the second secondary reflective mirror 7 and the minute surface of the first secondary reflective mirror 8 are oppositely arranged.
Wherein, first secondary reflective mirror 8 and the second secondary reflective mirror 7 are fixed by revolving support 4, and the first one-level reflective mirror 1 is arranged on above the second secondary reflective mirror 7, and is arranged on revolving support 4 rotationally by axle 2, wherein, axle 2 overlaps with the turning axle 10 of one-level rotary reflection assembly.
Rotational control assemblies comprises controller (not marking in figure) and driver, and driver comprises one-level driver 3 and two-stage actuator 5, and one-level driver 3 connects one-level rotary reflection assembly 13, and two-stage actuator 5 connects secondary and rotates reflection subassembly 14.As shown in Figure 3, one-level driver 3 coupling shaft 2, one-level rotary reflection assembly 13 can be rotated around axle 2, two-stage actuator 5 is arranged on the lower end of the second secondary reflective mirror 7, and connect revolving support 4 by bearing, the turning axle 11 making revolving support 4 can rotate reflection subassembly around secondary rotates, thus makes the first secondary reflective mirror 8 and the second secondary reflective mirror 7, and the turning axle 11 that the first one-level reflective mirror 1 all rotates reflection subassembly around secondary rotates.
The structure of rotational control assemblies is not limited to said structure, can change according to the quantity of one-level reflective mirror and secondary reflective mirror and position, therefore, conveniently mark and understand, be the structural representation after simplification in the following drawings, namely eliminate rotational control assemblies.Be illustrated in figure 4 the simplification structural representation of the specific embodiment shown in Fig. 3.
Further, the controller in this guiding device can have multiple control modes, such as, CPU is provided with in controller, carry out program setting to CPU, controller controls one-level driver and two-stage actuator according to setting data, thus device is rotated according to the mode of setting is regular.Again such as, controller electrical connection sensor, sensor can the change of perceived light source position, thus by Signal transmissions to controller, after controller carries out computing, by Signal transmissions to driver.No matter adopt which kind of type of drive, can the location tracking of implement device, and the manipulation of this device is simple, calculated amount is little.
Operation instruction is carried out as light source below using the sun.Apparent motion of the sun is the rotation due to the earth, makes to be positioned at tellurian people and thinks that sun every day is all rise eastwardly, fall again in west; Apparent motion of the sun is the one observation expression of people, and take that is observer as reference frame (assuming that observer keeps geo-stationary), then the sun is at the volley relative to observer.
And sun apparent place refers to the position of the sun seen from ground, represent as coordinate by sun altitude and solar azimuth two angles.Sun altitude refers to the angle of light from solar core direct projection to locality and local level.The orientation at solar azimuth and sun place, refers to projection and the locality meridianal angle of sunray on ground level, can regard as approx and be erected at ground straight line shade in the sun and the angle of Due South.The sunshine power on sun altitude and ground is closely related.Sooner or later have very large difference with the light intensity at noon, reason is just the difference of sun altitude.Solar azimuth determines the incident direction of sunlight, determines the hillside of all directions or the difference daylighting situation towards buildings.
When using this guiding device to follow the trail of the sun, the block position of reflection subassembly 14 is rotated by adjustment one-level rotary reflection assembly 13 and secondary, realize following the trail of sun particular location, enable this guiding device track the position of the sun exactly, thus make sunshine carry out derivation utilization by this guiding device.And the angle between the first one-level reflective mirror 1 and the first folded light beam being arranged in 45 degree, the light that light source is sent has stable and larger projected area on the first one-level reflective mirror 1, thus guarantees to collect a large amount of light, and carries out derivation utilization.
Of course, this guiding device is not limited to, for following the trail of the sun, also can be applicable to follow the trail of the celestial body such as the moon, star, can also be applied to the tracking to other form light sources, as laser, signal source or radiation source etc.
In addition, by reversible principle of light, this guiding device can also be applied the other way around, as shown in Figure 5.Secondary rotates the light that reflection subassembly sends for receiving light source, and be called incident beam P1 ', one-level rotary reflection assembly is for the formation of final light beam P3 '.Incident beam P1 ' rotates after reflection subassembly through secondary, and namely successively after the second secondary reflective mirror 7 and the first secondary reflective mirror 8, form the first folded light beam P2 ', wherein, incident beam P1 ' and final light beam P3 ' is all perpendicular to the first folded light beam P2 '.
And in prior art (see Fig. 1 and Fig. 2), there is a center blind zone G in range of receiving, this center blind zone causes because the first reflective mirror exists distance to rotation center C (center of circle of the center blind zone G namely shown in Fig. 2), when carrying out reception light to space, G place, center blind zone cannot receive light.In other words, if light source is arranged in this center blind zone G, the device of prior art cannot track, and because the second reflective mirror occupies rotation center position, this blind area cannot be eliminated.And apply this guiding device, above-mentioned problem can not be there is.
Further, in order to reduce installation difficulty, the first secondary reflective mirror in figure 3 and the second secondary reflective mirror can be replaced by a prism, for the ease of difference, this prism is defined as the first secondary prism 12, first secondary prism 12 is provided with 6 faces, i.e. first surface 121, second face 122, the 3rd face 123, fourth face 124, the 5th face 125 and the 6th face 126, as shown in Figure 6.Wherein, the second face 122 and the 5th face 125 are all coated with reflectance coating, be equivalent to the first secondary reflective mirror 8 and the second secondary reflective mirror 7 in Fig. 3, the angle namely between the second face 122 and the 5th face 125 is 45 degree.And first surface 121 is arranged perpendicular to the first folded light beam, the 3rd face 123 is arranged perpendicular to final light beam, and first surface 121 and the 3rd face 123 are provided with anti-reflection film, can reduce light attenuation.The benefit of application prism is, because prism can be prefabricated, therefore uses prism to replace two secondary reflective mirrors, can reduce the adjustment to the first secondary reflective mirror and the second secondary reflective mirror angle in installation process, greatly reduce installation difficulty.
In addition, in order to effectively save space, the first secondary reflective mirror can be arranged to concave mirror, as shown in figs. 7 to 9.First secondary reflective mirror 8 is concave mirror, second secondary reflective mirror 7 is arranged on the focal spot of concave mirror, and the position of the second secondary reflective mirror 7 can change according to the concave surface position of the first secondary reflective mirror 8, as shown in figs. 7 to 9, second secondary reflective mirror 7 is separately positioned on the top of the first one-level reflective mirror 1, middle part and below, when the second secondary reflective mirror 7 is positioned at top and the middle part of the first one-level reflective mirror 1, the first one-level reflective mirror offers groove, so that light passes.Because the first secondary reflective mirror 8 is provided with concave mirror, the second secondary reflective mirror 7 is arranged on the focal spot of concave mirror, therefore greatly can shorten the size of optical path length and reduction the second secondary reflective mirror 7, effectively save space and material cost.
In addition, the structure of this guiding device has diversity.Such as, secondary rotates reflection subassembly and comprises 3 secondary reflective mirrors, be defined as the 3rd secondary reflective mirror 15, the 4th secondary reflective mirror 16 and the 5th secondary reflective mirror 17 respectively, 3rd secondary reflective mirror 15, position between the 4th secondary reflective mirror 16 and the 5th secondary reflective mirror 17 can have multiple various combination, as shown in Figure 10-Figure 14.First folded light beam 22 forms final light beam 23 successively after the reflection of the 3rd secondary reflective mirror 15, the 4th secondary reflective mirror 16 and the 5th secondary reflective mirror 17.Wherein, the 3rd secondary reflective mirror 15, the 4th secondary reflective mirror 16 and the 5th secondary reflective mirror 17 are coated with reflectance coating, to reduce the decay of light.In like manner, 3rd secondary reflective mirror, the 4th secondary reflective mirror and the 5th secondary reflective mirror also can be replaced by a secondary prism, 3rd secondary reflective mirror, the 4th secondary reflective mirror and the 5th secondary reflective mirror are respectively the reflective surface of this secondary prism, light vertically enters this secondary prism incidence face, and vertically penetrate from this secondary prism exit facet, principle is the same, is no longer described in detail herein.
Further, the first one-level reflective mirror 1 in one-level rotary reflection assembly can be replaced by two one-level reflective mirrors.For the ease of difference, these two one-level reflective mirrors are defined as the second one-level reflective mirror 18 and the 3rd one-level reflective mirror 19 respectively.Angle between second one-level reflective mirror 18 and the 3rd one-level reflective mirror 19 is 45 degree, and incident beam 21 after the second one-level reflective mirror 18 and the reflection of the 3rd one-level reflective mirror 19, forms the first folded light beam 22 successively.Now, joint (i.e. O point) is between the second one-level reflective mirror 18 and the 3rd one-level reflective mirror 19, as shown in Figure 15 and Figure 16, Figure 15 and Figure 16 is respectively the replacement scheme of Fig. 4 and Figure 14, is replaced by two one-level reflective mirrors by the one the first one-level reflective mirrors 1.Second one-level reflective mirror 18 and the 3rd one-level reflective mirror 19 integrally, can rotate around the turning axle 10 of one-level rotary reflection assembly.
