On the evening of March 6th, Jingsheng Electromechanical Co., Ltd. announced that on January 12, 2018, it had signed equipment purchase and sales contracts with Inner Mongolia Zhonghuan Photovoltaic Materials Co., Ltd. (referred to as "Zhonghuan Photovoltaic"). These contracts involve the procurement of equipment for two key projects: the fourth phase of the silicon single crystal chip industrialization project and the fourth phase of the monocrystalline silicon material industrialization project for solar photovoltaic renewable energy cells. The first batch of equipment for both projects has now been ordered.
The total contract value amounts to 858.24 million yuan, which is expected to represent approximately 44.04% of the company’s 2017 annual revenue. This significant deal highlights the strong confidence that Zhonghuan Photovoltaic has in Jingsheng's technology and product quality. It also underscores the company’s growing influence in the high-end photovoltaic equipment market.
This business agreement further reinforces Jingsheng Electromechanical’s position as a leading supplier of monocrystal furnaces, driven by its advanced technological capabilities and competitive edge. By supplying cutting-edge production equipment to industry leaders, the company continues to strengthen its leadership in the solar photovoltaic sector. This development not only supports the growth of China’s renewable energy industry but also aligns with national goals such as “Made in China 2025,†aiming to promote high-end, intelligent manufacturing solutions.
Moreover, this contract demonstrates the company’s strong R&D capabilities and long-term strategic vision. As the demand for clean energy continues to rise globally, Jingsheng is well-positioned to play a pivotal role in shaping the future of the photovoltaic industry. With continued innovation and customer-focused solutions, the company is poised for sustained growth and success in the years ahead.
Fresnel Lens
The fresnel lens is a thin sheet made of plastic material. One side of the lens surface is smooth, and the other side is molded with concentric circles from small to large. Its grooves is designed from the interference of light, the relative sensitivity, and receiving angle requirements.
Compared to the conventional Spherical Lens, a Fresnel lens by the lens divided into a series of concentric circles theoretically infinite number of lines (i.e., the Fresnel zone) to achieve the same optical effect, while saving the amount of material For these lines, the overall thickness of the lens is reduced; ordinary Fresnel convex lens is actually a continuous curved surface is truncated to a section of a discontinuous change of the curvature as the surface is finely divided, so look like a
circle around the lines. Fresnel lenses may in fact be regarded as a series of prisms are arranged in a ring, wherein the relatively sharp edge, and the center of the convex surface is relatively smooth.
Fresnel lenses are mainly used in optical imaging industry ( projectors, VR, AR, etc.), Fresnel lenses are used in LED lighting distribution (spotlights, floodlights, stage lights, traffic signal lights), infrared induction lenses are used in ( industry 4.0 intelligent fields, building security systems, induction lighting, etc.), large Fresnel lenses are used in ( photovoltaic concentrated light generation, heat collection, light utilization, etc.).
