For a long time, the LED industry in Europe and the United States has taken the lead, monopolizing the intellectual property rights of sapphire substrates and silicon carbide substrate LEDs, and gradually evolved into a monopoly of high-end products, forcing the Chinese LED industry to operate in the low-end of the industry. The difficult reality has been stinging the entire Chinese LED production, learning, and research fields, and the voice of "China's creation" is increasing.
On January 8, 2016, the National Science and Technology Awards Conference was held in the Great Hall of the People in Beijing. Nanchang University, Jingneng Optoelectronics (Jiangxi) Co., Ltd. and China Energy Saving Crystal and Lighting Co., Ltd. completed the unit’s “high-efficiency nitrogen on silicon substrateâ€. The gallium-based blue light-emitting diode project won the first prize of the National Technology Invention. The main participants of the project include Prof. Jiang Fengyi, Vice President of Nanchang University, Dr. Sun Qian, Vice President of Jingneng Optoelectronics, CEO of Jingneng Optoelectronics, Dr. Wang Min, founder of Jinghe Lighting, and others.

In this project, Jinghe Lighting mainly undertakes the application development and test feedback of silicon substrate LEDs. The silicon substrate LED has good thermal conductivity, which greatly improves the reliability. It has advantages in applications such as high power and directional light. According to its characteristics and advantages, crystal and lighting have successfully developed a series of street lamps and tunnel lights. Products such as lamps and lanterns have successfully pushed high-power LEDs on silicon substrates to all parts of the world.
Leading the development of standardized module solutions to lead the development of LED street lamp industry
Jinghe Lighting was founded by the Applied Division of Crystal Energy Photonics. Founded by Dr. Wang Min in 2009, Jinghe Lighting inherits not only the silicon substrate technology, but also the innovative temperament in the “silicon substrate manâ€. .
At the beginning of Jinghe Lighting, the R&D team relied on the technical accumulation of Jingneng Optoelectronics LED chips for many years, thoroughly analyzed the defects of LED lighting products at that time, and developed the standard module street lamps.
Dr. Wang Min introduced: "At that time, LED street lights mainly solved three technical problems. The first is heat dissipation; the second is light distribution; the third is maintenance. The standard module solves these three problems together and solves the problem at the same time. Industrialization problems such as scale manufacturing and inventory."
Zhang Zhihai, chief engineer of Jinghe Lighting, further explained: "The standard module street lamp is based on a modular design, which accelerates air convection through the thermal honeycomb effect, improves surface heat exchange efficiency, and makes the LED temperature rise not exceed 35 degrees, thus ensuring LED lamps. The working life can achieve higher light efficiency and stable color temperature. In addition, the standardized module does not need to consider the dustproof and waterproof problem of the whole lamp. It specially considers the dustproof and waterproof design of the single module. And the optical lens array obtained by the invention patent has improved the overall lighting efficiency by 6%; the independent module is easy to disassemble and maintain in use, and saves the maintenance cost."

From the full-page streetlights at that time to modular streetlights, the LED lighting industry at that time was a breakthrough concept, and Jinghe Lighting led the development of the entire industry. Today, most LED streetlight factories have adopted modular solutions. Array lenses used in modular LED streetlights, the owner of their invention patents are also crystal and illumination.
Put forward the "changing face unchanged core" solution and the traditional lighting enterprise
Since the birth of LED lighting products, traditional lighting companies are facing a situation of demise without transformation, LED lighting companies have become the "revolutionaries" of traditional lighting companies. However, the transformation of traditional lighting companies is easy. Optics, thermodynamics, electricity, a large number of talents and a large amount of research and development investment make most small and medium-sized traditional lighting companies daunting.
LED lighting companies are also attacking. When traditional enterprises are in a difficult transition, Jinghe Lighting proposes the concept of LED module +, which provides standardized modules for crystal and lighting to replace traditional light sources, and guarantees any matching with traditional street lamp housings. , to avoid the competition between you and the traditional lighting companies. This innovation not only increased the sales of crystal and lighting modules, but also helped the traditional enterprises achieve a gorgeous turn. At the same time, users have obtained high-quality LED lamps and diversified street lamps to form a win-win situation.
Relying on silicon substrate technology, the first flat optical lens
The silicon substrate LED has good thermal conductivity due to its vertical structure, and its superiority is highlighted in the application of directional light. At present, most of the traditional optical lenses used, such as cylindrical mirrors or spherical mirrors, have a convex surface that is mostly convex, which is difficult to clean, and it is easy to accumulate dust on the lens, resulting in low luminous efficiency of the lens, affecting the lighting effect of the lamp, and greatly increasing the lighting. Maintenance difficulty and improved maintenance costs of lamps. Crystal and illumination successfully developed the industry's first planar optical lens based on the characteristics of LED-based LED light.
The planar light-emitting LED lens includes a top, a side and a bottom, a light-emitting surface at the top, a reflective cup surface on the side, and a concave cavity on the bottom. The illuminating surface is a plane, the inner cavity includes a top surface and a draft surface, and the top surface is a free surface. The convenience of lamp maintenance is greatly improved. After the lens surface area is dusted, it can be easily cleaned, so that the lamp maintains a high maintenance coefficient, maintains good optical performance, and can better exert the superior performance of the silicon substrate LED.
In recent years, the shipment of Jinghe Lighting LED tunnel lights has ranked the top three in the industry. TE series LED tunnel lights with flat lenses accounted for 80% of the 2015 tunnel light shipments.
Exalting the "Chinese Dream, China Core" National Flag for Model Innovation
In 2013, with the large-scale mass production of Crystal Energy's high-power silicon substrate chips, Jinghe Lighting officially shouted the slogan “China Dream, China Core†at the Guangzhou International Lighting Exhibition to establish a national LED application product brand. Image.
Chen Hao, President of Jinghe Lighting, introduced the company as a mission to promote silicon-based LED lamps. Based on silicon substrate technology, the company has established a complete lighting application system, including road lighting, tunnel lighting, office lighting, commercial lighting, and landscape. In the six fields of lighting and special lighting, the silicon substrate LED products are pushed all over the country and are going all over the world.
The silicon substrate LED is the technology of crystal and illumination, and the mode innovation is the core of the expansion of crystal and illumination.
In 2013, China Energy Conservation and Environmental Protection Group invested in Jinghe Lighting and became the controlling shareholder. Based on the deep technical background and the strong comprehensive strength of central enterprises, Jinghe Lighting has made strategic transformations, from simple technology-leading enterprises to energy-saving lighting integrators and operators, and achieved good results.
The transformed crystal and lighting highlight the strong advantages of comprehensive strength. In 2015, following the successful illuminating of Nanchang Metro Line 1, the company won the bid for the Nanning Metro Lighting Project and won a total investment of 290 million yuan. The current national energy-saving lighting PPP project - Sichuan Chongzhou project, while India 40,000 The BOT project of Yu Lan Street Light has also been officially signed, and the annual order amount exceeded 500 million yuan.
The road to innovation is long, and crystal and lighting have never stopped, because this spirit is derived from the bones!
