Optical member with fixed and aligned structure

An optical member, especially an optical member having a fixed and aligned structure.

Concentrating solar power generation obtains light energy by installing a concentrating solar receiver, which increases power generation efficiency by collecting a larger amount of light energy. Among them, when the solar light can be focused by the Fresnel lens, it can be concentrated into a transparent light guide column of a shape similar to an inverted pyramid type, that is, a homogenizer.

The underside of the homogenizer is a smooth plane whose main function is to homogenize the energy of the spot where the Fresnel lens is focused. If the energy of the spot is directly irradiated to the solar cell without first homogenizing it with a homogenizer, the energy thereof is too concentrated, resulting in a decrease in photoelectric conversion efficiency. Furthermore, since the illumination angle of sunlight is not constant, but it changes instantaneously with time, the concentrating solar cell module needs to be matched with the chasing system, and the chasing system will adjust the angle and immediacy. Adjust the best sunshine angle. One of the functions of the homogenizer is to improve the angular tolerance of the concentrating solar cell module and the dimensional tolerance of the module assembly, which is an important and functional component.

Nowadays, the homogenizer is often installed by manpower, and based on the functional requirements, the homogenizer is top-heavy in structure, and is only bonded with a layer of glue between the homogenizer and the concentrating solar cell. The support strength is insufficient, and it is easy to tilt or even peel off when the concentrating solar module performs solar tracking. In addition, the bonding between the homogenizer and the concentrating solar cell is just the light gathering place, and the temperature is the highest. If the bonding rubber is softened by heat, it will not be able to support the homogenizer. The weight causes the homogenizer to tilt, which seriously affects the functionality and reliability of the homogenizer.

Furthermore, the contact interface between the homogenizer and the colloid is also the key to light leakage. When the homogenizer is manually installed, if the homogenizer is directly pressed against the colloid without the auxiliary set height, the colloid will be pushed to the surface of the lower side of the homogenizer to adhere to the surface, that is, the overflow is generated. Glue phenomenon, and these colloids that are pushed to the lower surface of the side of the homogenizer by pushing will cause the loss of light energy, so that the light energy reaching the concentrating solar cell is reduced, and the efficiency is lowered.

The concentrating solar receiver with a fixed structure according to the application of the invention patent application No. 101148535 includes: a base; a concentrating solar cell disposed on the base; and a support member comprising: At least one fixing portion is located on one side of the concentrating solar cell, and has a bottom surface attached to the base; a supporting body is connected to the fixing portion, and a space is partitioned to accommodate the concentrating type a solar cell; and a perforated hole penetrating through a top surface of the support body, the through hole corresponding to the concentrating solar cell; and a averaging device penetrating the through hole and located in the concentrating solar cell Above.

However, the conventional technology still has the disadvantages of high material cost, high processing cost, large tolerance, poor weather resistance, etc. Firstly, in terms of material and processing cost, it is necessary to use a fixing portion and a supporting body to assemble a supporting body for fixing the light column. That is, more components need to be used, and therefore different components must be assembled, and the support body is to be machined through the through holes, and the fixed portion and the base are also processed to form a plurality of screw holes.

Due to the need to provide through holes, screw holes, and reassembly of the fixing portion and the support body, the tolerance problem of the prior art is caused. The prior art has at least two tolerances, the first being through holes and concentrating solar cells. The tolerance between the two, the second between the fixed part and the base Poor, the third is the tolerance between the fixed part and the support body.

In addition, the installation of the light column is often done by manpower. It is not easy to manually match the homogenizer with the concentrating solar cell. First, the human eye must first determine whether the homogenizer and the concentrating solar cell have been accurately matched. However, it is difficult for the human eye to accurately align the position of the homogenizer and the concentrating solar cell due to the viewing angle. Even an experienced professional can accurately and accurately align the relative positions of the halogen and the concentrating solar cell. The homogenizer is subject to multiple tolerances during the process of fixing to the concentrating solar cell, including the tolerance of the homogenizer shaking due to unstable movement when the fixed homogenizer is fixed, and the tolerance of the assembly of the homogenizer itself. Even when the homogenizer is fixed on the concentrating solar cell, deviation is easy to occur. Therefore, since the fixing and alignment of the homogenizer must be completed in stages, it is very time-consuming and labor-intensive to install the halogen. Excessively relying on manual alignment makes the alignment accuracy less precise. Therefore, it is necessary to provide an optical member with a fixed and alignment structure to enable the fixing and alignment of the optical member. Once completed, the effort to increase production efficiency will not only save time, while significantly improving alignment accuracy.

The main object of the present invention is to provide an optical member comprising a light guiding structure and a fixing structure for passing light, the light guiding structure being located inside the optical member, the fixing structure being located on an outer side of the optical member, the guiding light The structure is integrally coupled to the fixed structure, wherein the fixed structure has a positioning portion; and a solar receiver comprising at least a substrate and a photovoltaic element, the photoelectric element being disposed on the substrate corresponding to a surface of the optical member Corresponding to the light guiding structure, the substrate further has a limiting portion, and the positioning portion is combined with the limiting portion to interfere with each other.

The main feature of this creation is that the fixed structure of the creation is directly from the light guide The structure is formed into a one-piece structure, so that the optical member having the fixed and the alignment structure can be formed only once by processing, but the prior art must use more components, and it is necessary to process through multiple processes. The human assembly can fix the secondary optical component, so the material cost and processing cost can be effectively saved by the package structure of the secondary optical component provided by the present invention.

In particular, by providing a fixing structure on the optical member, the fixing structure itself can stand stably to support and hold the light guiding structure, and the fixing structure further has a positioning portion, so that when the positioning portion of the fixing structure is coupled to the limiting portion, The fixed effect produced by mutual restraint interference, as long as the positions of the components are properly designed, the light guiding structure can be accurately positioned on the photovoltaic element, so that no additional components or processes are required to keep the light guiding structure at a predetermined position, and must be again It is emphasized that the positioning portion and the limiting portion interfere with each other, so that the baking process does not shift when the colloid is not completely cured, because the optical member has been maintained in a stable equilibrium state and the constant holding position is fixed. The optical member with the alignment structure enables the fixing and alignment of the optical member to be completed at one time, which not only saves time and labor when the light guiding member is installed, but also increases the manufacturing efficiency, and greatly improves the alignment accuracy.
