Embodiment
With reference to specific embodiment, the invention will be further described.
As shown in figure 1, a kind of guide-lighting solar panel, including light guide plate 1, support 2, light source direction detector 3, convergence
Mouth 4 and fiber waveguide 5；The light guide plate 1 includes focusing lenslet array 11, single mirror grating 12, turning minute surface 13 and minute surface bottom
Disk 14, the light guide plate 1 is supported by support 2, and the convergence mouth 4 is located in the middle of the disk of light guide plate 1；The top of convergence mouth 4 is
Light source direction detector 3, the lower end of light source direction detector 3 is connected with fiber waveguide 5.
The light guide plate 1 is provided with one piece of focusing lenslet array 11, the side of being shaped as of the focusing lenslet array 11
Shape, circle, polygon or irregular shape, material are acrylic plastic material or glass material.
One piece of single mirror grating is placed on the back focal plane of the focusing lenslet array 11 of light guide plate 1, grating shady face is
Minute surface that can be reflective.
There are the turning minute surface 13 of a cambered surface, the cambered surface center of circle of turning minute surface 13 on the downside of the hole of single mirror grating 12/seam
In convergence mouth 4 side.
One minute surface chassis 14 arranged at the bottom of light guide plate 1, and the sunny slope on the minute surface chassis 14 is minute surface, and with level side
To there is certain angle, i.e., the chassis away from convergence mouth 4 side should be slightly above convergence mouth 4 side.
The main function of light source direction detector 3 is the incident direction of real-time monitoring sunshine, when sunshine is not vertical
When incident, it can pass out signal, and then adjust by mechanical system the incline direction of light guide plate, until sunray again
Untill vertical incidence light guide plate.When sunshine passes through focusing lenslet array 11, according to lens principle, light can be accumulated
A hot spot is formed on back focal plane.The array of single mirror grating 12 on back focal plane, hot spot can enter leaded light through via/seam
The inner side of plate 1.As shown in Fig. 2 the right side light of single lens can be directly entered the inner side of light guide plate 1, through minute surface chassis 14 and list
The inner side of mirror grating 12 carries out multiple reflections, is eventually accumulated at convergence mouth 4.But the left side light of single lens due to
The reason for incident direction, it can fall on turning minute surface 13.Because the center of circle of turning minute surface 13 is located at side at convergence, so light
It can be reflected and to converging out propagation.Now come if the light of more lateral is propagated through, and direction is the position of hole/seam again just
Put, then the backside reflection that the light can be abducted angle mirror face 13 is fallen, so light still can be to convergence due to crooked radian outwards
Propagate at place.
Embodiment 1：Guide-lighting solar panel (having light source direction detector)
One piece of single mirror grating 12, single mirror grating are placed on the back focal plane of the focusing lenslet array 11 of light guide plate 1
12 shady face is minute surface that can be reflective, and single mirror grating 12 is hole grating, and it is micro- that the aperture of hole grating is placed exactly in focusing
In the focus of lens array 11.The material of single mirror grating 12 is metal or glass.The vertical radian of the turning minute surface 13
For 1/4 circle, horizontal arc be 1/2 circle, medial and lateral be can reflection light minute surface.
The main function of light source direction detector 3 is the incident direction of real-time monitoring sunshine, when sunshine is not vertical
When incident, it can pass out signal, and then adjust by mechanical system the incline direction of light guide plate, until sunray again
Untill vertical incidence light guide plate.When sunshine passes through microlens array, according to lens principle, light can be accumulated back focal plane
One hot spot of upper formation.Hole grating array on back focal plane, hot spot can be entered through small holes on the inside of light guide plate.Such as Fig. 2
Shown, the right side light of single lens can be directly entered on the inside of light guide plate, many through being carried out on the inside of minute surface chassis 14 and hole grating
Secondary reflection, is eventually accumulated at convergence mouth 4.But the left side light of single lens can be fallen due to incident direction
On turning minute surface 13.Because the center of circle of turning minute surface 13 is located at side at convergence, so light can be reflected and to converging out
Propagate.Now come if the light of more lateral is propagated through, and direction is the position of aperture again just, then the light can be abducted
The backside reflection in angle mirror face 13 is fallen, due to crooked radian outwards, so light still can be to propagation at convergence.
Embodiment 2：Guide-lighting solar panel (gauge without light source directional detector)
The planar solar concentrator of gauge without light source directional detector, its difference maximum with embodiment 1 is the aperture in the grating of hole,
Become the slit of strip, turning minute surface is become 1/2 open tubular column along the axis incision of cylinder by original 1/4 hollow ball
Body, and cylinder the center of circle still at convergence side.As shown in Figure 3.
When sunshine passes through microlens array, according to lens principle, light, which can be accumulated on back focal plane, forms one
Hot spot.Grating array on back focal plane, hot spot can be entered by slit on the inside of light guide plate.As shown in Fig. 2 single lens
Right side light can be directly entered on the inside of light guide plate, through carrying out multiple reflections on the inside of minute surface chassis and slit grating, eventually
It is accumulated at convergence mouth.But the left side light of single lens can be fallen on turning minute surface 13 due to incident direction.
Because the center of circle of turning minute surface 13 is located at side at convergence, so light can be reflected and to converging out propagation.Now if
The light of more lateral, which is propagated through, to be come, and direction is the position of slit again just, then the light can be abducted the back side in angle mirror face 13
Reflect away, so light still can be to propagation at convergence due to crooked radian outwards.When light is all accumulated at convergence,
Converge out to couple and pass through fiber waveguide light and transfer out.
It is described above, only it is presently preferred embodiments of the present invention, any formal limitation not is made to the present invention, it is any ripe
Professional and technical personnel is known, it is without departing from the scope of the present invention, real to more than according to the technical spirit of the present invention
Apply any simple modification, equivalent substitution that example made and improve etc., still fall within technical solution of the present invention protection domain it
It is interior.
