The specific embodiment
The sunshine conduction device that is used for the hypogee illumination provided by the invention, the parallel sunshine that sunshine is effectively pooled enhancing is exported, and then through the mirroring of curved surface leaded light underground building is shone.Below in conjunction with concrete embodiment and accompanying drawing the present invention is done further detailed description, said is to explanation of the present invention rather than qualification.
Referring to Fig. 1, Fig. 2; A kind of sunshine conduction device that is used for the hypogee illumination; Comprise condenser system and light-conducting system, wherein condenser system comprises: with the folding face type condenser 12 and parabolic curved surface of column Light-modulating mirror 11 that optical axis is fixedly connected, folding face type condenser 12 has identical focus with parabolic curved surface of column Light-modulating mirror 11; Be in the both sides of focus respectively, folding face type condenser 12 is towards sun setting;
Light-conducting system comprises: curved surface leaded light mirror 21 with lose tube 22;
The parallel sunshine of parabolic curved surface of column Light-modulating mirror 11 reflections reflexes to the tube 22 of losing that is arranged on the top, hypogee through curved surface leaded light mirror 21 and throws light on.
Concrete: folding face type condenser 12 constitutes (referring to Chinese patent 200410025904.6) by the installing rack with parabolic cylindricality reflection folding face with several level crossings that are arranged on the installing rack, also is provided with sunshine outgoing groove 13 on the installing rack.
Folding face type condenser 12 is in the opposite direction with the reflective surface of parabolic curved surface of column Light-modulating mirror 11, is mounted for integrative-structure with opposed facing mode.After flat capable sunshine converges through folding face type condenser 12, according to the principle of reversibility of light path, again by the parallel sunshine after having same focal point and parabolic curved surface of column Light-modulating mirror 11 becoming to strengthen with the reflection mode conversion again, from 13 outputs of outgoing groove.
Further, folding face type condenser configuration 12 has automatic sunlight tracking device, and automatic sunlight tracking device is regulated folding face type condenser, makes its plane of the opening be in the vertical direction with solar light irradiation all the time.
Described automatic sunlight tracking device is that the polar coordinates type automatic sunlight tracking device (can adopt existing automatic tracking system; Such as Chinese patent 200910254627.9); Its sunlight signal acquiring devices is installed on the reception plane of folding face type condenser, and the optical axis of sunlight signal acquiring devices is parallel with the optical axis of folding face type condenser; Sunlight signal acquiring devices is transferred to control module with it, by control module the drive unit that drives folding face type condenser 12 and rotate is controlled, with the plane of the opening of regulating folding face type condenser 12 towards.
Parallel sunshine again through the parallel sunshine after becoming enhancing after the parabolic curved surface of column Light-modulating mirror 11 adjustment light paths, is exported from the outgoing groove 13 of parabolic cylindricality reflection folding face installing rack after folding face type condenser 12 converges then.Curved surface leaded light mirror 21 all is the curved surface of high reflectance with losing tube 22, such as being made up of high curved surfaces of surface reflectivity such as SUS304 type stainless steel or silver mirror reflecting glasses.
Referring to Fig. 3; Opening length L, the width W of described folding face type condenser 12 depends on that respectively system's optically focused ratio is the luminance parameter requirement of L/W and underground garage; For example when requiring the optically focused ratio to be the octuple of common sunlight intensity, if be the Cross section Design of collimated light beam W1 * W=0.5W m according to the height situation of underground garage or top, tunnel circular arc
2, the opening length L=0.5 * 8=4m of then corresponding folding face type condenser 12.
Referring to light path signal shown in Figure 1; Owing to adopted automatic sunlight tracking device to drive; The plane of the opening of assurance folding face type condenser 12 is in the vertical direction with solar light irradiation all the time, thus the effect that assurance is at utmost converged parallel sunshine; Because so parabolic curved surface of column Light-modulating mirror 11 is installed on the folding face type condenser 12 identical optical axises and has identical focal point F according to the light path principle of reversibility; Just become the parallel sunshine of enhancing and output from its outgoing groove 13 through the sunshine after 11 reflections of parabolic curved surface of column Light-modulating mirror, realized the target of raising of enhancing or the solar energy density of sunlight intensity.But at this time the parallel sun direction of light of enhancing of output still changes along with the time.In order to reduce cost, adopt curved surface leaded light mirror 21 with its all with the reflection mode import lose tube 22 after, directly get into hypogee (such as underground garage) again, realize the direct illumination of high efficiency sunshine.
