Detailed Description
Fig. 6 schematically shows a split fixed trans-reflective solar light transmission device 10 with a reflective handle according to the present invention split by solar light transmission units 9.
Fig. 1 schematically shows a solar light transfer unit 9 of the present invention comprising a front single or multi-layered fresnel lens convex lens 1, a rear single or multi-layered positive or negative fresnel lens convex or concave lens 2, a reflective stem 3, a reflective stem tip front convex lens 4, a reflective stem tip rear concave or convex lens 5, and an optical fiber 6.
The single-layer or multi-layer fresnel lens group (single-layer or multi-layer lens group) 7 is a device that condenses sunlight into a condensed parallel beam. FIG. 2 schematically shows two design approaches for a single or multilayer Fresnel lens group (single or multilayer lens group): 1) a single-layer or multi-layer Fresnel lens-inverse Fresnel lens group (single-layer or multi-layer convex lens-concave lens group), wherein the focal point of the front single-layer or multi-layer Fresnel lens 1 is coincident with the virtual focal point of the rear single-layer or multi-layer inverse Fresnel lens 2-1; and 2) a single or multi-layer Fresnel lens-Fresnel lens group (single or multi-layer convex lens-convex lens group) in which the front single or multi-layer positive Fresnel lens 1 focal point coincides with the rear single or multi-layer Fresnel lens 2-2 focal point.
Reflective handle 3 is a device that reflects incident concentrated parallel light beams of various angles to a handle-end optical fiber (or light pipe). The reflective handle back face can be designed for different aspect ratios. The reflective handle reflects the concentrated parallel light beam incident from the single-layer or multi-layer fresnel lens group (single-layer or multi-layer lens group) to the handle-end optical fiber (or light pipe). After incident sunlight with different angles passes through the single-layer or multi-layer Fresnel lens group, the concentrated parallel light beams are emitted into different areas of the reflecting handle. The concentrated parallel light beams are reflected to the reflecting handle-end optical fiber through the designed reflecting surface with a special angle. Fig. 4 and 5 illustrate sunlight transmitting paths of sunlight transmitting units including a single-layer or multi-layer lens group design one and a single-layer or multi-layer lens group design two, respectively.
The key points of the invention are as follows: the design of the reflective handle 3. According to the optical principle, the normal vector of the reflecting surface at different positions on the back surface of the reflecting handle can be obtained by applying a normal vector obtaining formula of the reflecting surface on the back surface of the reflecting handle. The reflecting handle surface is divided into grids with equal or unequal distances, and the reflecting surfaces which accord with the normal vector of the reflecting surface are sequentially filled from the left side to the right side to the middle from top to bottom to form the back surface of the complete reflecting handle. The front surface of the reflective handle may be shaped similarly to the back surface of the reflective handle to facilitate mating. The reflection handle end lens combination adjusts the maximum angle incident light to be within the critical incidence range of the optical fiber (or the light pipe).
The normal vector of the reflecting surface on the back surface of the reflecting handle is obtained by the following formula: fig. 3 illustrates the coordinate axes of the solar light transmission unit. The direction of the rear single-layer or multi-layer Fresnel lens parallel to the edge of the reflecting handle is the X-axis direction, and the direction of the spoon part of the reflecting handle is the positive direction; the direction of the side perpendicular to the X axis in the contact surface of the rear single-layer or multi-layer Fresnel lens group 7 and the reflecting handle 3 is the Y axis direction; the direction vertical to the contact surface of the rear single-layer or multi-layer Fresnel lens group 7 and the reflecting handle 3 is taken as the Z-axis direction; the positive directions of the Y axis and the Z axis are determined by a right-hand rule; and then, establishing a coordinate system by taking the symmetrical central point of the contact surface of the single-layer or multi-layer Fresnel lens and the reflecting handle as an origin.
1) For the single-layer or multi-layer lens group 7, the coordinates of the central point of the reflecting surface on the back surface of the reflecting handle are (x, y, -h), and the normal vector of the reflecting handle is (v × f1 × x/(z × u (h)) -w × x, v × f1X y/(z × u (h)) -w × (g + b/2+ y), v × f2+ w × (h-d)). Wherein u (h) ═ h × f1+f2×(f1-f2)]/(z×f2)；v＝{[f1×x/(z×u(h))]2+[f1×y/(z×u(h))]2+f2 2}-0.5；w＝[x2+(g+b/2+y)2+(h-d)2]-0.5；f1And f2The focal length of the front single-layer or multi-layer Fresnel lens convex lens and the virtual focal length of the rear single-layer or multi-layer inverse Fresnel lens concave lens are respectively. b. d and g are indicated by reference numerals, and h is the thickness (determined by design) of the reflection handle at the central position point of the corresponding reflection area on the reflection handle.
2) For the second design of the single-layer or multi-layer lens group 7, the coordinates of the center point of the reflecting surface on the back surface of the reflecting handle are (x, y, -h), and the normal vector of the reflecting handle is (-v × f1 × x/(z × u (h)) -w × x, -v × f1X y/(z x u (h)) -w x (g + b/2+ y), -v x f2+ w x (h-d)). Wherein u (h) [ -hxf1+f2×(f1+f2)]/(z×f2)；v＝{[f1×x/(z×u(h))]2+[f1×y/(z×u(h))]2+f2 2}-0.5；w＝[x2+(g+b/2+y)2+(h-d)2]-0.5；f1And f2The focal length of the front single-layer or multi-layer Fresnel lens convex lens and the focal length of the rear single-layer or multi-layer Fresnel lens convex lens are respectively. b. d and g are indicated by reference numerals, and h is the thickness (determined by design) of the reflection handle at the central position point of the corresponding reflection area on the reflection handle.
