Description

TECHNICAL FIELD

[0001] The utility model relates to a light-gathering equipment, relates to photovoltaic, photo-thermal and lighting industries. BACKGROUND

[0002] The light-gathering system is a device for gathering light energy, mainly applied in the field of solar energy. Solar energy is inexhaustible and clean, and it is of great significance to the survival and development of mankind to develop solar energy in today's global energy shortage and serious environmental pollution. Due to the sparse distribution of sunlight and low energy density, large-area collection is required to obtain high power, which requires the use of a large amount of artificial light-receiving materials. Therefore, the behavior of using solar energy itself is often difficult to achieve high efficiency and environmental protection. The silicon crystal solar power station is the mainstream way of artificial use of solar energy at present. It uses large-area distributed silicon crystal solar cell panels to convert solar energy into electric energy and then concentrates it through wires for consumption or transmission. The main problem of this structure is that more than 80% of the composition of the silicon crystal solar cell panel is silicon, with a melting point of more than 1000 degrees Celsius. The processing itself is high-energy consumption, and it is born with a heavy "carbon debt", which needs to serve for a long period of time to achieve the goal of contributing to environmental protection. A large number of metal conductive strips are connected to the battery piece unit, and reliable waterproof and insulation protection is required throughout the process. The material composition and processing technology are relatively complex, and it is not convenient to recycle after scrap. Improper handling or direct abandonment will cause environmental pollution. The battery panel is relatively heavy, and it needs a high-strength frame and support. The overall structure uses a lot of materials and is heavy, which requires a high load-bearing capacity of the roof and may cause safety hazards. The battery panel needs to be exposed to sunlight to obtain as much light energy as possible. The accompanying contradiction is that exposure to sunlight can easily cause the battery temperature to be too high and reduce the power generation efficiency. The battery panel is generally installed in a place without shelter. The roof and open field are more ideal. A large amount of conductive material is prone to electrical safety accidents in thunderstorm weather, and the protection level needs to be increased. The battery panel is the most vulnerable part of the solar power station, and the manufacturing and maintenance cost accounts for the largest proportion of the total cost, which is not conducive to improving economic efficiency and carbon contribution performance. Concentrated solar power station (CPV) is another structure for converting solar energy. It first uses a light-gathering device to concentrate sunlight over a large area and then uses it. It is highly expected in the industry's future prospects and is hailed as the second generation of solar power stations because it does not have the above-mentioned problems of silicon crystal solar power stations. The main types of current concentrated solar power stations are Fresnel lens light-gathering power stations and plane mirror matrix light-gathering power stations. Their light-gathering methods have a common fatal weakness - they need light source tracking devices to assist and accurately focus the dispersed collected light on a point, which has the problems of high manufacturing and installation precision, large space occupation, high energy consumption and high comprehensive cost. The light-gathering device is an important link to improve the performance of the concentrated solar power station, and there is still much room for improvement. CONTENT OF THE UTILITY MODEL

The matrix layer and the light collecting layer adopt a split structure, or the matrix layer is integrated with the light collecting layer at the end of the light collecting unit. In this paper, the same or different directions of light refer to the same direction within the necessary precision and the specific observation angle, for example, in the observation dimension of Figure 1 the ends of all the light collecting units 2 are directed to the right, and the emitted light is also directed to the right, so the directions of the light can be regarded as the same, even though they can be quite different from the perspective of the normal direction of the matrix layer. In the light collecting plate, the transverse direction refers to the arrangement direction of the light collecting units of the matrix layer at the end thereof, the longitudinal direction refers to the stacking direction of the matrix layer and the converging layer, and the lateral direction refers to the direction perpendicular to the transverse direction and the longitudinal direction.

The other layers have the same structure, except that the inclination of the light collecting unit changes from layer to layer, and the inclination of the last layer can cause the emitted light to undergo total reflection in the converging layer. The core layer of the light collecting unit is a book-like structure cut from a whole piece of material. In order to save materials, the first and second layers adopt a connected structure, or a single structure like the lowermost layer. The converging layer can input or output from one or multiple sides; Figure 1 The converging layer 3 inputs from the top and outputs from the right side, which is single-sided input and single-sided output. A second matrix layer can be added below the converging layer 3, facing the opposite direction of the matrix layer 1, so that the converging layer 3 can input from below and output from the left side. Multiple-sided input can expand the source of light, and multiple-sided output can achieve load distribution or avoid excessive load concentration to prevent the temperature of the component from being too high. Figure 8 The converging layer 25 is a flat plate, and the second converging layer 28 is a straight strip, which is essentially a narrow and long plate structure.

In order to reduce the light loss, the thickness of the cladding layer 32 or the incident angle of the light is as small as possible, and the cladding layer 32 is made of a material with a refractive index close to that of the core layer 31, so that the angle between the light entering the core layer from the side surface and the side surface of the core layer is increased, but the total reflection condition is still met.
