Hongli Zhihui and Jingyuan Optoelectronics form a strategic partnership with car-level LEDs
On October 27, Hongli Zhihui announced the signing of a Strategic Cooperation Agreement with Jingyuan Optoelectronics Co., Ltd. (referred to as "Jingyuan Optoelectronics"). The collaboration focuses on the automotive lighting sector, where both companies have already integrated LED products into their offerings. With LED lighting seen as a key growth area in the future, the partnership aims to leverage each other's strengths, share resources, and achieve mutual benefits.
The development and certification of car-level LED products typically involve long cycles, which is why the two parties have agreed on a four-year strategic cooperation period. Hongli Zhihui will provide its proprietary LED chips, which are then packaged into automotive-grade LED lamp beads by Jingyuan Optoelectronics. This joint effort is expected to accelerate product development and enhance market competitiveness for both sides.
Under the agreement, from November 2017 to October 2021, Hongli Zhihui or its subsidiaries will purchase automotive-grade LED chips from Jingyuan Optoelectronics, with an estimated total value of approximately RMB 500,000, subject to market fluctuations within a ±15% range.
The cooperation includes several key components: regular communication between senior management, joint product development, and the integration of new technologies. Hongli Zhihui is committed to adopting Jingyuan Optoelectronics’ latest products and prioritizing the sharing of test data and reports to support product improvement. Additionally, the company will provide quarterly forecasts and monthly demand plans to Jingyuan Optoelectronics, ensuring timely production and supply.
This partnership is expected to address challenges related to large-scale production of LED chip intellectual property, ensure stable and cost-effective supply of automotive-grade LED chips, and enable faster access to advanced LED technology for automotive applications. It also supports Hongli Zhihui’s broader strategy to strengthen its position in the LED automotive lighting market.
