Top 5 Chinese Companies Innovating LED and COB Lens Solutions

CALIFORNIA, CA, UNITED STATES, October 30, 2026 /CourierPR/ -- ZHEJIANG, CHINA, 30 OCTOBER 2026, In the rapidly evolving landscape of optical lens manufacturing, five leading Chinese companies are setting the stage for innovation in LED and COB lens solutions. According to a recent guide, Zhejiang Bicom Optics Co., Ltd, Changchun Sunday Optics Co., Ltd., ECOPTIK (CHANGCHUN) LTD, Ningbo Sunny Automotive Optech Co., Ltd., and DongGuan YuTong Optical Technology Co., Ltd. are among the top players in the custom optical lens market.

The global optical lens market was valued at USD 21.08 billion in 2025, with a significant focus on LED secondary optics and COB lenses. These lenses are crucial for applications ranging from automotive lighting to industrial and imaging uses. By 2030, vehicles equipped with adaptive driving beam (ADB) headlights are expected to reach a 23.8% penetration rate, driving demand for advanced optical solutions.

Zhejiang Bicom Optics Co., Ltd., established in 2005, has over 20 years of experience in optical lens manufacturing. The company operates from a 90,000 m² production base, employing approximately 700 people and producing 90,000,000 pieces annually. It boasts an R&D team of 50, with a focus on custom optical components, including LED optical lenses, automotive lighting lenses, and machine vision lenses. Bicom Optics can produce high-precision thick-wall lenses up to 50 mm thick and automotive light guides up to 1,300 mm long. The company can run two-colour and three-colour parts in a single production cycle, making it well-suited for complex lens assemblies.

The company's product examples include the DB1102 linear lens, designed for linear LED luminaires and indoor linear lighting, with applications in display lighting, industrial lighting, architectural wall washing, and machine vision lighting. The DB1072 Fresnel lens targets large-area lighting, solar concentration, and sensor applications, where thickness and weight are critical. In the automotive sector, Bicom Optics offers a low-beam collimator, a high-beam collimator, a combined low- and high-beam headlamp lens, an ambient lighting light guide, and a thick-wall rear turn-signal optic.

Bicom Optics holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, and its automotive supply chain is certified under TS16949. The company has received more than 167 patents, including 17 invention patents and 150 utility model patents. Its R&D centre is recognized as a Research and Development Center of High-tech Enterprises, with provincial-level awards in Zhejiang.

Changchun Sunday Optics Co., Ltd., based in Changchun, Jilin, operates in a region known for its precision optics industry. The company's production route is a key consideration for buyers, as it can either fabricate or mold lenses, depending on the specific part requirements. For LED or COB secondary optics, buyers should request detailed information on the manufacturing route, optical drawings, surface form and transmission measurements, material grade certificates, and cavity numbers.

ECOPTIK (CHANGCHUN) LTD, another Changchun-based company, operates under an international trading style, making it suitable for export documentation and foreign-language engineering communication. Buyers should verify the legal entity and ensure that the quality-management certificate is held by the manufacturing site, not just a parent or affiliate.

Ningbo Sunny Automotive Optech Co., Ltd., based in Ningbo, Zhejiang, focuses on automotive optics. Suppliers in this category are typically expected to operate under an automotive quality-management system, support APQP and PPAP documentation, maintain traceability by cavity and batch, and demonstrate photometric performance against regulatory requirements. Automotive programmes also lock tooling early, so mold ownership, tool-transfer conditions, and end-of-production obligations should be settled in the contract.

DongGuan YuTong Optical Technology Co., Ltd., located in Dongguan, Guangdong, benefits from its proximity to a large concentration of LED module makers, luminaire assemblers, and tooling shops. This location allows for shorter tooling turnaround and easier co-location of mold trials with the customer's LED module. Buyers should verify whether optical surface design is done in-house, whether the mold shop is in-house, and the class of cavity steel and polishing used. A controlled environment for molding and inspecting optical parts is also crucial.

These companies are at the forefront of innovation in LED and COB lens solutions, catering to a wide range of applications from automotive lighting to industrial and imaging uses. Their expertise and certifications position them as reliable partners for buyers seeking high-quality, custom optical lenses.
