Company History

Shandong Taihe Energy Co., LTD (Shenzhen Leadray Optoelectronic) for the solar lighting industry's first military qualified enterprises, in strict accordance with the military standards for the delivery of high quality products.

The Entrepreneurial Exploration Period: A Sprout of Light, Joining the Green Lighting Wave 【2006~2010】

In 2006, global environmental awareness was gradually awakening, and the limitations of traditional energy sources were becoming increasingly apparent. Solar energy, as a clean and sustainable energy source, was widely optimistic about its application prospects. Driven by a passion for green energy and a keen insight into future lighting trends, we resolutely plunged into the solar street light industry and founded Leadray.

At that time, solar street lights were still a nascent technology, with immature technology and high costs. Working in a simple office environment, our team embarked on a difficult journey.

On the one hand, we visited research institutes and universities, exchanged and collaborated with experts in photovoltaics and electronics, and absorbed cutting-edge technological concepts.

On the other hand, we worked closely on the production line, repeatedly disassembling and studying domestic and foreign solar street light samples, analyzing the performance of every component. After countless trials, we successfully overcame the difficulties of solar panel and battery compatibility, initially achieving stable charging and discharging, and launched the first generation of simple solar street lights.

Technological Breakthrough and Expansion Period: Forging Ahead, Illuminating the Path of Innovation and Development 【2011-2016】

With growing market awareness of solar street lights and a gradual increase in orders, the company entered a critical period of development. In 2012, the company decisively increased its R&D investment, establishing a professional R&D team comprised of professionals from diverse fields, including electronic engineering, mechanical design, and materials science.

At the same time, it invested in advanced production equipment and testing instruments, establishing standardized production workshops, and improving production capacity and product quality consistency.

In technological R&D, the team continuously focused on industry pain points. Addressing the low conversion efficiency of solar panels, after two years of research, they successfully introduced new photovoltaic materials and optimized the panel structure, increasing conversion efficiency from 20% to 40%, significantly increasing the power generation of the street lights.

In terms of energy storage, they developed a high-performance lithium-ion battery suitable for solar street lights. Compared to traditional lead-acid batteries, it is 33.3% lighter and has a 45.6% longer cycle life. It also features overcharge, over-discharge, and short-circuit protection, and can withstand extreme temperatures ranging from -20°C to 50°C. These two core technological breakthroughs have propelled the company's product performance to the forefront of the industry.

During this period, the company actively expanded its market presence. Domestically, it established partnerships with municipalities and contractors in numerous regions, and its products have been illuminating major urban thoroughfares and rural roads.

Overseas, the company participated in international lighting exhibitions. Its superior products and high-quality service attracted customers in Europe, America, Africa, Southeast Asia, and other regions. Its products were exported to 36 countries and regions, and its annual sales have doubled for three consecutive years. The company's scale has continued to grow, and it has established a strong presence in the industry.

Despite the crude appearance and limited lighting duration of the initial product, its unique advantages of "zero electricity costs and easy installation" garnered positive feedback from pilot applications in surrounding villages and small industrial parks, earning the company its first valuable investment and strengthening the team's resolve to further develop the solar street light industry.

Diversified Development and Industry Leadership: Leveraging Accumulated Strength to Lead the New Era of Solar Lighting【2017~2025]

 

In 2016, with the rise of emerging technologies such as 5G, the Internet of Things, and artificial intelligence, the solar street light industry ushered in a wave of intelligent transformation. The company seized this opportunity and embarked on a diversified development strategy.

 

First, it deepened technological innovation, integrated emerging technologies, and launched a series of smart solar street lights.

 

These street lights not only intelligently dim based on ambient light and foot traffic, but also integrate security cameras, Wi-Fi hotspots, and weather monitoring, becoming a key component of the "new infrastructure" for smart city development. Second, it expanded its product line to include outdoor lighting such as solar garden lights, landscape lights, and lawn lights, meeting the personalized needs of various scenarios.

 

To strengthen its leading position in the industry, the company actively participated in the formulation of national and industry standards, leading or participating in the drafting of 46 solar street light-related standards to promote standardized development in the industry.

 

 

 

Furthermore, it strengthened industry-university-research collaboration, established joint R&D centers with renowned domestic universities, and continuously cultivated and recruited high-end talent to maintain its technological leadership.

 

On the manufacturing side, we've incorporated Industry 4.0 concepts to create a smart factory, achieving automated, information-based, and intelligent management of the production process. This has resulted in a 66.5% increase in production capacity and a reduction in product defect rates to below 16.2%.

 

Today, the company has become a leading solar streetlight company integrating R&D, production, sales, and service. We have three production bases, two R&D centers, and three sales and service locations worldwide, with a total workforce of over 300.

 

Our products have illuminated 37 countries and regions worldwide, serving over 25,600 customers, making significant contributions to global energy conservation, emission reduction, and green lighting.

 

Looking ahead, the company will uphold the philosophy of "innovation-driven, green development," continue to deepen its presence in the solar lighting industry, and use technological innovation to paint a beautiful blueprint for green smart cities.
