Lens array type light energy collecting and transmitting system

Abstract

A lens array type light energy collecting and transmitting system mainly comprises a light energy collecting unit and a light energy transmitting unit. The light energy collecting unit consists of a lens array, and light energy is collected by the aid of the lens array and then is gathered to the light energy transmitting unit. The light energy transmitting unit consists of three portions, the first portion includes optical fiber couplers corresponding to small lenses of the lens array in a one-to-one manner, light is collected to the optical fiber couplers by the aid of the small lenses, the second portion includes sub optical fibers corresponding to the optical fiber couplers in a one-to-one manner, the light energy is transmitted to the sub optical fibers by the aid of the optical fiber couplers, the third portion includes a main optical fiber gathering the previous sub optical fibers, and the sub optical fibers transmit the light energy gathered and transmitted by the lens array to the optical fiber couplers to the main optical fiber, so that the light energy is collected and transmitted. The system is low in cost, the light energy can be collected in a large area, and low-loss transmission of the light energy is realized.

Description

technical field [0001] The invention belongs to the application field of light technology, in particular to a lens array type light energy collection and transmission system. Background technique [0002] Solar energy is an inexhaustible clean energy. After the solar radiation passes through the atmosphere, more than 99% of the solar radiation energy is distributed between the wavelength 0.15pm-4.0pm, and more than 90% is concentrated in the wavelength range of 0.4μm-2μm. About 40% in the visible spectrum and about 60% in the infrared spectrum. Solar cookers that have been widely used at present use concave mirrors or lens focusing methods to focus sunlight, but since energy must be taken at the focal point of the concave mirror, the light-gathering area of ​​the concave mirror cannot be made too large, otherwise the use will be affected. Another disadvantage of this technology is that it can only be used alone and cannot be connected in series, and the focus energy density...

Problems solved by technology

However, although these methods solve the problem of light energy collection and conversion, they all have their own defects, such as high cost and inability to transmit long-distance.
