In any moment in system cloud gray model, the position angle (Solar Latitude) B (55) of the angle P (47) between the normal (46) of optical position sensor (12) and its projection line (56) on minute surface (2), angle T (51), altitude of the sun α (Solar Altitude) (60) and the sun meets following relation:
unit: degree
Wherein: L=tan (B-180 ゜) and
When above-mentioned relation is met, the sunlight (21) of directive minute surface (2) is reflexed on optical position sensor (12) and Primary Receiver (15) Fresnel lens simultaneously.Then optical position sensor (12) is done to continue adjustment to main rotating shaft (6) and time turning axle (3) by controller (9), ensure how the position of the no matter sun changes, the size of the angle (65) between sunlight (21) and Fresnel convex lens (15) keeps invariable.
Fig. 4 is another one embodiment of the present invention.Compared with embodiment shown in Fig. 3, system of originally executing in example is still by the slant setting that is exposed to the north, but Primary Receiver (15) is a level crossing (40), but not a Fresnel lens.Optical position sensor (12) is positioned between minute surface (2) and minute surface (40), and the normal (46) of its place plane (62) be parallel to these two opticses central point between line (69).The installation site of optical position sensor (12) is positioned at the drop shadow spread of minute surface (2) on optical position sensor (12) place plane (62); And the projection of minute surface (40) in plane (62) cover by minute surface (2) projection on this plane.For this point is described, ask for an interview the projection vertical line of Fig. 4 center line (43) for drawing from the edge of Primary Receiver (15) to plane (62); And the projection vertical line of line (48) for drawing from the edge of minute surface (2) to plane (62).
In this example, the angle between the axis (61) of main rotating shaft (6) and horizontal vertical line (50) is T (51), equals 30 degree.The normal that line (46) is optical position sensor (12), the angle at itself and minute surface (2) place plane (39) is angle P (47).Altitude of the sun α (SolarAltitude) is angle (60).The position angle B (Solar Latitude) of the sun, can see the angle (55) in Fig. 3 though cannot embody in detail in this figure.The principle of work of system is explained in figs. 2 and 3.In the operational process of the present embodiment, minute surface (2) rotarily drives by main rotating shaft (6) and time turning axle (3), ensures that angle P (47) meets following condition all the time:
unit: degree
Wherein: L=tan (B-180 ゜) and
In this example, as long as above-mentioned condition is met, a branch of sunlight (37) in any moment is all reflexed in optical position sensor (12) by minute surface (2).Optical position sensor (12) is done to continue adjustment to main rotating shaft (6) and time turning axle (3) by controller (9), ensures that sunlight (38) is irradiated on minute surface (40) with constant incident angle (41) after leaving minute surface (2).Because minute surface (40) is hard-wired, so sunlight (38) is reflected as the fixing solar beam (42) in direction by further.Then, solar beam (42) is transported into the region that indoor arrival finally needs to throw light on after subsequent receiver process.
Figure 5 shows that according to another embodiment of the present invention, is how to be applied in actual building in order to illustrative system, and discloses its illumination and energy-saving effect.This embodiment has installed day of the present invention optical transmission system.As shown in the figure, wall (44) is the facade in a building orientation south, it has window (22) and (26).The platform (27) be connected with facade (44) installs two and has overlapped apparatus of the present invention (23) and (33), and container and content thereof have been arranged on respectively forms (22) and (26) top by stationary installation (28) and (29).The principle of work of system and each ingredient position relationship are explained in detail in Fig. 2-4.The top of the furred ceiling layer that face (24) are this architecture storey in Fig. 5, (25) are the end of this furred ceiling layer, are also the indoor roofs of above-mentioned floor simultaneously.This floor is divided into Liang Ge region, north and south by wall (30), has vertical window (22) and (26) in region, southern side (31), and region, north side (32) then lose direct sunlight all the year round.As shown in Figure 5, after incident sunlight is irradiated to a device (23), sunlight is reflexed to building interior by system, northwards transmit in furred ceiling layer inner space, after run into a subsequent receiver (17), an i.e. catoptron (36), sunlight vertical reflection is entered the bottom of region, north side (32) by it, achieves and utilizes sunlight to carry out the object of throwing light on.Also describe system in Fig. 5 in detail and how sunlight is carried out secondary distribution at building interior.When sunlight is irradiated to after on another this device (33), furred ceiling interlayer is entered by reflection, successively light deflection device (34) and (35) are run in way, the reflection of this sunlight is entered region, north side (32), thus realization natural sunlight illuminates the object loseing sunshine region all the year round.
Facts have proved, the present embodiment has outstanding energy-conservation and illuminating effect.In this example, the daylighting area of optics lighting device is 1 square metre, and after 150:1 optically focused, the diameter of directional light is 100mm, then the diameter of light path is 100mm.The roof that to suppose one 28 layers of overall height be the building of 100 meters uses this system to send light to basement, then the length of light path is about 100 meters.When the directivity deviation degree of the sunlight of systematic reflection is 0.01 degree, after system proceeds to terminal in the optical path, its deviation distance is=100 meters × tan (0.01)=17.5mm, then system effectiveness is 82.5%, the most high peak lighting power that can produce is about 800 watts, be equivalent to 2400 watts of fluorescent lamp lighting power, lighting area is 240 square meter.
Figure 6 shows that according to another embodiment of the present invention.In this embodiment, system is exposed to the north inclination 30 degree.Optical position sensor (12) is installed between two fixed optics parts, is respectively Primary Receiver (15) and subsequent receiver (17).Primary Receiver (15) is a level crossing (40), and subsequent receiver (17) is a Fresnel lens (70).Fresnel lens (70) place plane is (77), and has two vertical with it projection lines (78) and (79).As shown in projection line (78) and (79), level crossing (40) and the projection of Fresnel lens (70) on sensor place plane (62) overlap completely.The particular location of optical position sensor (12) falls within that optics flashed back the sunlight to it, namely within the scope of the projected area of level crossing (40) in plane (62).The normal (46) of optical position sensor (12) is parallel to the line (71) of level crossing (40) and both central points of Fresnel lens (70).
In the present embodiment, between optical position sensor (12) and optics lighting device (2), there is an optics possessing reflection function, i.e. level crossing (40).Now, level crossing (40) can be taken as a minute surface under a mathematical definition in Euclidean space.Now, as shown in normal in figure (46), i is orthogonal with optical position sensor (12) light-sensitive surface and a vector of light-sensitive surface is left in direction.So, i defines vectorial I (73) after the mirror-reflection orthogonal transformation in an Euclidean space.Then now have: between vectorial I (73) and optics lighting device (2) place plane (39), define angle Q (76).
Now, in the operational process of system, minute surface (2) rotarily drives by main rotating shaft (6) and time turning axle (3), ensures that angle Q (76) meets following condition all the time:
unit: degree
Wherein: L=tan (B-180 ゜) and
The wherein position angle (SolarLatitude) of α to be altitude of the sun (Solar Altitude), B the be sun.
In this example, as long as above-mentioned condition is met, a branch of sunlight (37) in any moment is all first reflexed on minute surface (40) by minute surface (2), then is reflexed in optical position sensor (12) by minute surface (40).Optical position sensor (12) is done to continue adjustment to main rotating shaft (6) and time turning axle (3) by controller (9), ensures that sunlight (38) is irradiated on minute surface (40) with constant incident angle (74) after leaving minute surface (2).Because minute surface (40) is hard-wired, so sunlight (38) is reflected as the fixing solar beam (42) in direction by further.Then, solar beam (42) is irradiated in optical position sensor (12), and makes sensor produce feedback signal.Controller (9) adjusts the attitude of main rotating shaft (6) and time turning axle (3) continuously according to feedback signal, ensures that the size of the angle (67) between solar beam (42) and sensor place plane (62) keeps immobilizing.Because controller (9) can carry out digitized sampling to the feedback signal of optical position sensor (12), this fixed angle (67) can physical location by artificially defining in controller (9) easily and adjusting without the need to changing optical position sensor (12).Therefore, in system cloud gray model, because fixed angle (67) is achieved, and optical position sensor (12) is parallel with Fresnel convex lens, thus be irradiated to the solar beam (42) on Fresnel lens (70), the angle (75) between (72) and Fresnel lens also can keep invariable.Like this, no matter in one day, the position of the sun is where, light beam (42), (72) all invest Fresnel lens (70) with constant angle (75), and can transmit by multistage subsequent receiver thereafter, the indoor appointed area of final arrival, reaches the object of natural lighting.
System drive optics lighting device and sunshine form certain angle, and sunlight is invested subsequent receiver step by step with specified angle, thus reach the object of transmission daylight.The light beam be transmitted keeps substantially parallel characteristic, therefore can carry out without medium long-distance transmissions in atmosphere.The feature of system is the attitude of real-time closed-loop adjustment optics lighting device under control system, ensures sunshine to invest Primary Receiver and follow-up multistage receiver with the most accurate direction, reaches the object of beam Propagation being carried out to the far-end of building interior throwing light on.
In a word, foregoing embodiments illustrates, the present invention utilizes loop control theory to carry out Dynamic controlling to the direct of travel of sunshine, ensures that it keeps the characteristic of its less parallel light to advance according to set direction, thus has broken away from day optical transmission system to the dependence of optical fiber.The system made based on the present invention can conveniently utilize facade to carry out collection and the utilization of sunshine, and the existing window of building and furred ceiling sheaf space can be utilized to carry out conduction and the sub conductance of light, do not rely on any non-air media such as optical fiber, achieve the architecture-integral daylight illumination of high-efficient simple.Because light collecting device can press close to outside or the installation of transparent curtain wall inside suspension of elevation of building, the central point of all movable parts is fixed, and optical device is that dispersion is placed, so the impact of system by wind reduces greatly.The present invention with the application of architecture-integral in can place many cover systems simultaneously, and light intensity between many cover systems can cross complementary, and where accomplish the position of the no matter sun, the solar flux that system provides to building interior is basicly stable.These design features above-mentioned are that other designs are unexistent.
The present invention is not limited to embodiment discussed above.Be intended to explain and the technical scheme that the present invention relates to is described to the description of embodiment above.Above-described embodiment is used for disclosing best implementation method of the present invention, can apply numerous embodiments of the present invention and multiple alternative to reach object of the present invention to make those of ordinary skill in the art.Based on the present invention enlightenment apparent conversion or substitute also should be considered to fall into protection scope of the present invention.
