A kind of outdoor solar light source collection condenser lens

Abstract

This utility model discloses a focusing lens for outdoor solar light source collection, including a focusing lens body, a connecting ring, and a mounting base. The connecting ring is located at the bottom of the lens body, and the mounting base is located at the bottom of the connecting ring. A gate cut edge is provided on one side of the connecting ring and the mounting base. This utility model, through an innovative parabolic injection gate design, changes the traditional flow mode where the gate is perpendicular to the product's Z-axis direction. This makes the injection pressure consistent with the direction of the parabolic tangent of the arc vector, allowing the fluid to more easily reach the top of the sphere. Under the same injection pressure, the product surface can more easily reach a saturated state, ensuring that the surface accuracy meets optical requirements. This effectively solves the problem of shrinkage and unsaturation caused by conventional gate designs, improves the accuracy of the optical surface, and thus enhances the focusing effect of the focusing lens, enabling the product to focus at a point and meet the high requirements of outdoor solar light source collection.

Description

Technical Field

[0001] This utility model relates to the field of focusing lens technology, specifically a focusing lens for collecting outdoor solar light sources. Background Technology

[0002] In the field of outdoor solar energy collection, the condensing lens plays a crucial role, as its optical performance directly affects the efficiency of solar energy collection. Currently, existing condensing lenses have several design and manufacturing issues. Due to optical requirements, the product's wall thickness is often excessive, reaching a maximum of 38.5mm. Even after multiple adjustments to the injection molding process, conventional gate designs still exhibit unsaturated shrinkage on the product's curved surface, compromising optical surface accuracy and resulting in poor focusing performance. Furthermore, in conventional gate designs, the gate flow is perpendicular to the product's Z-axis, making it difficult for injection pressure to reach the spherical apex, leading to insufficient surface saturation and severely impacting optical performance, failing to meet the high requirements of outdoor solar energy collection for condensing lenses.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-4 This utility model provides a focusing lens for collecting outdoor solar light sources, including a focusing lens body, which includes a lens body 1, a connecting ring 3 and a mounting base 2. The bottom of the lens body 1 is provided with the connecting ring 3, and the bottom of the connecting ring 3 is provided with the mounting base 2. A gate cutting edge 4 is provided on one side of the connecting ring 3 and the mounting base 2.

[0019] The lens body 1, the connecting ring 3, and the mounting base 2 are integrally injection molded.

[0020] Specifically, the condensing lens body is obtained by integrally injection molding the lens body 1, the connecting ring 3, and the mounting base 2.

[0021] The mounting base 2 has a hole number 5 on one side of its bottom.

[0022] Specifically, cavity number 5 is used to identify condenser lenses of different specifications or batches, facilitating production management and quality control. The gate trimming edge 4 is connected to the parabolic injection gate 6.

[0023] Specifically, the gate trim 4 is connected to the parabolic injection gate 6. This design optimizes the injection process, allowing the molten plastic to fill the mold more evenly, reducing the generation of bubbles and shrinkage marks, and improving the optical performance of the product.

[0024] The cross-section of lens body 1 is an aspherical optical surface.

[0025] Specifically, the cross-section of lens 1 is an aspherical optical surface, which can more effectively converge light and improve light-gathering efficiency.

[0026] The condenser lens body is made of PMMA material.

[0027] Specifically, the condenser lens body is made of PMMA material, which has good transparency, weather resistance and processing performance, and can meet the needs of outdoor solar light source collection.

[0028] In practical application, during the injection molding process, an innovative parabolic injection gate design (6) is adopted. The injection pressure acts on the spherical surface of the condensing lens body along the parabolic direction, allowing the injection fluid to smoothly reach the top of the spherical surface, ensuring surface saturation of the product and guaranteeing optical surface accuracy. Compared with traditional gate designs, the condensing lens of this invention significantly improves both spherical saturation and focusing effect. Products with traditional gate designs have a shrunken and concave top of the spherical surface, resulting in poor focusing effect and scattering. In contrast, the top of the spherical surface of the product of this invention is more easily saturated, resulting in better focusing effect and the ability to concentrate light at a specific point.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
