Secondary optical component package structure

A package structure of a secondary optical component, in particular, a package structure of a secondary optical component in which the light guide member is integrally formed to effectively save material and processing cost, thereby minimizing tolerance, and the support unit can surely support and position the body, so that The body maintains a stable balance and a fixed position, which helps the bonding process to keep the transportation process stable and not displaced.

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.

Today's homogenizers are often installed by manpower, but based on functional requirements. Therefore, the homogenizer is top-heavy in structure, and is only bonded with a layer of glue between the homogenizer and the concentrating solar cell, so the support strength is insufficient, and it is easy to perform solar tracking in the concentrating solar module. Tilt, even peel off. 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 weight of the homogenizer and cause the homogenizer to tilt, which seriously affects both. The functionality and reliability of the light.

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. More components need to be used, and therefore must be assembled, and the support body is to be machined through the through hole, and the fixing portion and the base are also processed. A plurality of screw holes are formed.

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 second is the tolerance between the fixed part and the base, and the third is the tolerance between the fixed part and the supporting body.

Furthermore, the prior art fixes the homogenizer with a support member, and the two are heterogeneous materials. Therefore, the expansion coefficients of the materials are different. Considering the concentrating solar cell that needs to be used in a high temperature environment for a long time, it is easy to cause deformation and subsequent interface. Stripping problem.
