Embodiment
The invention will be further described below in conjunction with drawings and Examples.As shown in Figure 4, sunshine concentrating method of the present invention, the light path principle that adopts is: the refractive index of supposition square wedge type optically denser medium body is 1.5, and sunshine enters the wedge inclined-plane that optically denser medium constitutes by optically thinner medium, and the long right angle face plating mirror of wedge.When incident light HD with α
1During=36 ° of incident angle incidents, DF is a refract light, respectively through A, and F, the D point is made the straight line AE perpendicular to LN, CF, DG is through the straight line BF of F point work perpendicular to MN.If LM=1, LN=6, ∠ LMN=90 °, α then
29.594 ° of=∠ LNM=arcsin (1/6) ≈,
∵LN⊥CF?MN⊥BF
∵∠BFC＝∠LNM＝α
