Basis of the present invention is a lock arc of lighting group.Lock arc of lighting group is meant in transparent base material such as glass, air one group of arc reflector layer (promptly locking arc of lighting) is set that light can arrive exiting surface from the incidence surface of this group lock arc of lighting, but can't turn back to incidence surface from exiting surface.
For solid substrate materials such as glass, the lock arc of lighting can be in glass or other substrate, inlay can be reflective reflector layer, also can be in substrate the groove of open arc shape, plate one deck reflector layer then; For with the situation of air as substrate, the lock arc of lighting can be the paillon foil that the two sides all is coated with reflector layer, uses iron plate, aluminium flake, glass sheet etc. usually.Reflector layer can be the thin layer that aluminium lamination, silver layer or other can reflection rays.
Lock arc of lighting group is divided into into light face and exiting surface according to the direction that enters and penetrate of light, its design main points are that end points enveloping surface (being exiting surface) of being formed in a plurality of lock arc of lighting bright dippings position is as much as possible little with the angle at lock arc of lighting bright dipping position, preferably tangent, just can guarantee that light can only unidirectionally arrive exiting surface from advancing the light face, and can't turn back to into light face from exiting surface.
The surface of lock arc of lighting is an arc, and best profile is an arc surface, and the design parameter of recommendation is a radius R, and arc angle is 90 °.When forming unidirectional lock light district, adjacent two lock arc of lightings need spacing distance d of translation to place, require d＜＜R, should get R/d in the design〉2.5, recommend design parameter R/d=6～9, under this parameter, can guarantee that all will be directed to exiting surface from the light that advances the light face and enter.
The ultimate principle of lock arc of lighting group is exactly to utilize in the process of light interreflection between two lock arc of lightings, incident ray and reflection ray must be observed the rule with the normal symmetry, utilize curved reflecting surface to reflex to the exiting surface direction to light step by step from the incidence surface direction, as long as the arc profile is appropriate, in this reflection process, light just can not enter from incidence surface again and return from incidence surface, thereby has guaranteed that light can only enter from incidence surface, penetrates from exiting surface.
Lock arc of lighting group constitutes optical devices that light are delivered to exiting surface from incidence surface, this optical devices have the characteristic that makes light can only enter from incidence surface, penetrate from exiting surface, and this characteristic and the light angle when entering incidence surface is irrelevant, and the frequency-independent of incident light.
Utilize the lock arc of lighting group can only unidirectional characteristic by light, can make multiple optical devices, for example can directly be placed in exiting surface etc. to solar energy photovoltaic panel, but the higher a kind of method of efficient is that light is imported to specific outlet, its method is for connecing light pipe after lock arc of lighting group, light pipe has only with lock arc of lighting surface of contact and light-emitting window and is not coated by reflector layer, all the other inside surfaces are all coated by reflector layer, so light can only penetrate from light-emitting window, thereby reach the purpose that all light is all concentrated on light-emitting window.

A corresponding lock light chamber of lock arc of lighting group (lock light chamber is meant the stationary installation on lock arc of lighting group and border thereof), and one or more light pipes, Fig. 2 is to be a kind of design proposal of substrate with the air, in this scheme, 1 lock light chamber is furnished with 6 light pipes (2 above light pipes are formed the conduit room) and has formed a lock optical mechanism.Lock arc of lighting length is L, and xsect can be coated with reflector layer with the sheet iron two sides and make for the radius R angle is 90 ° a arc-like sheet.Guarantee that by locating device every adjacent two lock arc of lighting relative spacing distances are d, the enveloping surface that lock arc of lighting upper end constitutes is an incidence surface, the tangent line of lock arc of lighting upper end is vertical with incidence surface, and the enveloping surface that lock arc of lighting lower end constitutes is an exiting surface, and the tangent line of lock arc of lighting lower end overlaps with exiting surface.Light enters from lock arc of lighting incidence surface, always can enter some light pipes by exiting surface, the tubular structure that light pipe surrounds for the inner sheet iron that is coated with reflector layer, side towards the lock arc of lighting leaves opening, therefore locking arc of lighting can enter the light pipe from the light that penetrates, light pipe axially with lock arc of lighting quadrature, two ends will not be sealed, wherein an end as light-emitting window and an other end as light guide opening.Lock arc of lighting and light pipe can separately be made.
Principle of work of the present invention is: light enters after the lock light district of lock arc of lighting, interreflection in the middle of two lock arc of lightings, and light just can enter light pipe, as shown in Figure 3.In the process of reflection, initial angle regardless of light, light all will obtain to point to from C the speed component of D direction in lock light district, after injecting light pipe from the lock arc of lighting, light also has the speed component that points to the D direction from C in light pipe, promptly light is moved to the direction of D by C in the process of light pipe conduction.Light pipe is a tubular structure, and light-emitting window is positioned at an end of light pipe, all is coated with reflector layer except that light-emitting window, light conducts in the leaded light chamber, have three kinds of situation: A. and reflected by the light pipe outer wall, if incident light has the speed component that points to light-emitting window, then this speed component is constant in the reflection process; B. reflected by the lock arc of lighting of lock arc of lighting and light pipe intersection, owing to lock the one side and leaded light tubular axis parallel longitudinal or almost parallel of arc of lighting exiting surface to light pipe, the speed component that light points to light-emitting window is constant substantially in reflection process; C. light penetrates from light-emitting window.Two characteristics of A, B have guaranteed that light always penetrates from light-emitting window, and can not lock arc of lighting by reflected back, promptly lock the function that arc of lighting has played unidirectional lock light.
In the said process, the incident angle of light, the wavelength of light do not influence final result.
For solid substrate materials such as glass, light-emitting window can be the plane, can be convex surface also, decides on design requirement, and as base material, light-emitting window should be handled as the plane when carrying out theoretical analysis for gas.Light-emitting window can be axial along light pipe, can be not axial along light pipe yet, for example can along with light pipe axially vertical vertically open a light-emitting window, under latter event, can increase mirror structure, horizontal direction of light is reflexed to the direction of light-emitting window, and this method is a method conventional on the optics.
Need to prove, the lock optical mechanism is not necessarily plate shaped, also can be by arcwall face or various irregularly shaped the composition, as shown in Figure 4, as long as according to first lock arc of lighting, the thinking of light pipe is gone design then, just can reach the purpose that the light of separate sources is transferred to constant outlet light.
The light that penetrates from light-emitting window can import to the optical fiber through the optical fiber import system, carries out follow-up processing again, also can directly handle as a kind of light source.
In practical application; the luminous energy that one mortice lock optical mechanism can pin is limited; therefore use a plurality of lock optical mechanisms usually and form the lock photosystem; as shown in Figure 5; the light inlet of all these lock optical mechanisms is exempted to have formed one and is gone into optical plane; these top, plane all angles; the light of each wavelength; after entering the lock arc of lighting; as long as be directed in the light pipe; just all will penetrate from light-emitting window, if each light inlet is all installed the optical fiber import system, then optical fiber will be introduced in the optical fiber; therefore it can utilize full angle; full wave light has improved the utilization ratio of light widely.The used lock arc of lighting of this lock photosystem can be the full lock optical mechanism that coats, and also can be the nude enamelled lock optical mechanism that covers, and both efficient are suitable substantially, but the nude enamelled cost that covers the lock arc of lighting will hang down.
In order to save the usage quantity of optical fiber import system, also can adopt a lock arc of lighting that coat, single light-emitting window that laterally place, complete, its incidence surface is aimed at the light-emitting window of other lock arc of lighting, guarantee that the light that other lock arc of lightings are assembled all enters into this laterally lock arc of lighting, just can all be directed to this laterally light-emitting window of lock arc of lighting to these light of locking arc of lighting, import in the optical fiber by the optical fiber import system again.This scheme can reduce the usage quantity of optical fiber import system greatly.
Use device provided by the present invention, the spoke degree improves the energy utilization efficiency of sunshine greatly, can be widely used in the luminous energy acquisition phase that photo-thermal power generation, water heater, solar telephone etc. utilize the equipment of sun power.
