Embodiment Construction

[0012] Fig. 1 shows an embodiment of the present invention, a solar concentrator equipped with a one-dimensional refractive lens manufactured according to the method of the present invention. In the figure, the refractive lens 1 is made of silica gel directly on the glass plate 2 through a mold to form many silica gel lenses 3 . The silicone lens 3 has two mutually non-parallel planes, that is, the oblique refraction plane 4 and the flat refraction plane 5 . Because it has two plane refraction surfaces, it is different from the situation that the common focusing convex lens has a focus. In the figure, the light emitted from the refraction lens 1 has refraction but no focus, and its projection area on the photocell 6 is still a light band. . The included angles between the two refraction surfaces of the adjacent silicone lenses 3 are different, so that the projection areas of the refracted light of all the silicone lenses 3 on the converging plane 7 are accurately overlapped t...

Abstract

The invention relates to a manufacture method of a glass plate silica gel solar light concentrating lens and a solar light concentrating device. Vulcanization or solidification material such as silica gel and ultraviolet solidification resin are directly manufactured on glass plate through a mould, or a semi-finished lens which is made of silica gel or the resin is connected on the glass plate, or silica gel or resin is firstly manufactured on the glass plate and then a refractive face of the light concentrating lens is processed and made to manufacture a light concentrating lens which comprises a Fresnel lens and a dioptric lens. The less sheet of the dioptric lens has two flat refractive faces which are not parallel with each other. The light concentrating device is composed of a solar light concentrating lens which is manufactured with the method in the invention, a solar light tracing mechanism and a shell body. The invention has the beneficial effects of high lens precision, higher solar transmissivity, jarring tolerance, light weight and low manufacture cost. The silica gel product is tolerant of ultraviolet rays. Two actualizing examples are given out in the form attached drawing.

Description

technical field [0001] The invention relates to a method for manufacturing a glass plate silica gel solar concentrating lens and a solar concentrating device. Background technique [0002] Concentrated solar power can reduce the amount of photovoltaic cells, improve efficiency and reduce costs. Using a Fresnel lens has higher light-gathering efficiency than reflection, and it is more convenient to track. However, the curved surfaces of some existing glass condenser lenses need to be processed by a special grinding machine, and the efficiency is low. Contents of the invention [0003] One of the objectives of the present invention is to provide a method for manufacturing a glass plate silica gel solar concentrating lens. [0004] Glass plate silica gel sun concentrating lens manufacturing method of the present invention comprises that vulcanizable or curable material such as silica gel and ultraviolet curable resin are directly manufactured a concentrating lens on glass p...
