Embodiment
The exemplary embodiments that embodies characteristic of the present invention and advantage will be described in detail in following explanation.Be understood that the present invention can have various variations on various embodiment, its neither departing from the scope of the present invention, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the present invention.
Following mask body is introduced the lens unit array condenser of the preferred embodiment of the present invention.
Lens unit array condenser of the present invention can be used for thermomotor, also can be used for utilizing other solar utilizing equipment of solar energy heating, for example powerful solar water heater.
As shown in Figure 1, the lens unit array condenser of the embodiment of the invention comprises lens unit 1, support member 2 and substrate 3.In the present embodiment, the line number and the columns of lens unit 1 are 16, but not as limit.
As shown in Figure 2; The bottom surface 30 of substrate 3 is planes, so substrate 3 is the plane substrate, and is as shown in Figure 2; Optically focused focus O is arranged directly over the geometric center point Q of substrate; Distance between optically focused focus O and the substrate center's point Q can confirm that the area of condenser is big more by the area of the required condenser of reality, and then the distance between optically focused focus O and the substrate geometric center point Q is then big more.With relative support member 2 or lens unit 1 near substrate geometric center point Q is internal layer; With relative support member 2 or lens unit 1 away from substrate geometric center point Q is skin; For example the lens unit 1 of innermost layer is four, and outermost lens unit is 4 (lens units 1 of position, four angles) in the present embodiment.
As shown in Figure 2, the upper surface of substrate 3 is formed with the support member array, and the support member array comprises the support member 2 of multiple lines and multiple rows; Preferably the line number of support member array is identical with columns; But not as limit, also can line number different with columns, each support member 2 upper surface supports a lens unit 1; In this instructions; The surface that support member 2 is connected lens unit 1 is called supporting surface; Because supporting surface is the plane preferably; Therefore also can be described as supporting plane; The geometric center point P of the supporting plane of each support member 2 is preferably at sustained height, in other words conj.or perhaps on the plane of same line perpendicular to substrate geometric center point Q and optically focused focus O, and equal with the distance (line space) of the geometric center point P conllinear of the supporting plane of each support member 2 in the delegation and adjacent two geometric center point P; Also all the distance (column pitch) of conllinear and adjacent two geometric center point P is equal for the geometric center point P of the supporting plane of same each support member 2 that lists, and line space equals column pitch.
The geometric center point of each support member 2 is preferably at sustained height, and like this, the minimum point of mounted lens unit 1 is not higher than the peak with the lens unit 1 of this lens unit 1 internal layer adjacent.Like this, the height of support member 2 can be too not high, helps the making of mould, reduced the cost of condenser.The benefit of peak that the minimum point of mounted lens unit 1 is not higher than the lens unit 1 of internal layer adjacent also is to have difference in height between the adjacent lens unit 1, reserve suitable operating space can on support member 2 the fixing len unit.The nearest place of adjacent two lens units 1 also will keep the distance of 2-5mm.
Certainly, also can be the geometric center point height that the geometric center point height of outer field relatively support member 2 is higher than the support member 2 of relative internal layer.
As shown in Figure 3; The incident light a of the line d that is parallel to substrate geometric center point Q and optically focused focus O of lens unit 1 is concentrated on optically focused focus O after the reflected light b of the geometric center point P of each lens unit 1 reflects through lens unit 1; Fig. 3 also can be regarded as being cut by O, P, 3 determined planes of Q the figure of lens unit 1 gained, and solid line N is the normal of lens unit 1, and dotted line e is parallel to normal N; Dotted line d is on the line of substrate geometric center point Q and optically focused focus O, and dotted line c is perpendicular to line d.
Equally, Fig. 3 has also provided the method that angle is set how to confirm each lens unit 1.Lens unit 1 is as the plane; Inevitable normal perpendicular to each position on the lens unit 1, also inevitable perpendicular to normal (or claim normal vector) N of lens unit 1, so at its geometric center point P place; Confirm normal N, just can confirm the angle that is provided with of lens unit 1.Incident light a be the equal of source point be lens unit 1 geometric center point P and to directly over (also promptly with the line parallel direction of substrate geometric center point Q) ray of extending with optically focused focus O; Reflected light b is the equal of that source point is the geometric center point P of lens unit 1 and another ray of extend past optically focused focus O; The normal N coplane at the geometric center point P place of this two ray and lens unit 1, and normal N is divided the angle of this two ray equally.Therefore,, promptly can confirm the normal N at the geometric center point P place of lens unit 1 again through the method for asking the angle bisector, and then confirm the angle that is provided with of each lens unit 1 through confirming above-mentioned two rays.
Simultaneously; Also can confirm the angle that is provided with of lens unit 1 through confirming the lens unit 1 and the mode of the folded acute angle of the bottom surface 30 of substrate 3; At first, lens unit 1 need be perpendicular to the determined plane of geometric center point (also being the subpoint Q of optically focused focus O on the bottom surface 30 of substrate 3) by geometric center point P, optically focused focus O and the substrate of lens unit 1, is h with the geometric center point P of lens unit 1 apart from the distance of the bottom surface 30 of substrate 3; Optically focused focus O is m apart from the distance of the bottom surface 30 of substrate 3; The geometric center point P of lens unit 1 is n apart from the distance (also being the distance of P, R point-to-point transmission) of dotted line d, because normal N equates that with the folded acute angle of solid line b lens unit 1 is α with the folded acute angle of the bottom surface 30 of substrate 3; Then solid line b and the folded acute angle of dotted line c equal the α that 90 degree deduct twice, can get through the inverse trigonometric function computing:
Lens unit array condenser of the present invention; Optically focused focus O can be not yet directly over the geometric center point of substrate 3; At this moment, incident light is still perpendicular to substrate 3, but and be not parallel to the line of substrate geometric center point Q and optically focused focus O; At this moment; The incident light that remains perpendicular to substrate 3 is concentrated on optically focused focus O at the reflected light of the geometric center point P of each lens unit 1, remains and uses the normal N of confirming the geometric center point P place of lens unit 1 through the method for asking incident light and catoptrical angle bisector, and then confirm the angle that is provided with of each lens unit 1.Lens unit 1 is that α still satisfies with the folded acute angle of the bottom surface 30 of substrate 3:
Here; H still is the distance of the geometric center point P of lens unit 1 apart from the bottom surface 30 of substrate 3; M still is the distance of optically focused focus O apart from the bottom surface 30 of substrate 3; N still is the distance of the geometric center point P of lens unit 1 apart from optically focused focus O and the line of optically focused focus O between the subpoint on the bottom surface 30, and lens unit 1 is still perpendicular to geometric center point P, optically focused focus O and the optically focused focus 1 determined plane of subpoint on the bottom surface 30 of substrate 3 by lens unit 1 here.If optically focused focus O is not directly over any point on the substrate 3; But the plane, 30 place, bottom surface of the substrate outside the substrate 33 certain any directly over; Also be optically focused focus O at the subpoint on the substrate 3 not in bottom surface 30; But in the plane at place, bottom surface 30, be that 30 subpoint calculates above-mentioned angle to optically focused focus O in the bottom surface then with the subpoint of optically focused focus O in the plane at 30 places, bottom surface.
