Shenzhen Zijing Optoelectronics Technology Co., Ltd. Quality Control

International Standards:

Our products have passed rigorous third‑party testing and comply with major international standards:

• CE – Conformity with health, safety, and environmental protection requirements for products sold within the European Economic Area. This includes both electromagnetic compatibility (EMC) and low voltage (LVD) directives.
• RoHS – Restriction of Hazardous Substances, ensuring our projectors are free from lead, mercury, cadmium, hexavalent chromium, PBB, PBDE, and four phthalates (DEHP, BBP, DBP, DIBP).
• FCC – Compliance with U.S. Federal Communications Commission regulations (Part 15B) for electromagnetic interference, certifying that our devices do not cause harmful interference and are suitable for the American market.

Quality Management System:

We operate under a strict internal quality management system certified to ISO 9001:2015 standards. From incoming material inspection to final product release, every step follows documented procedures and quality checkpoints. Our system covers the entire process: raw material verification, in‑process quality control, 72‑hour burn‑in testing, and 100% final inspection. Regular internal audits and continuous training keep our team aligned with international best practices. We also maintain traceability records for each production batch, enabling quick root cause analysis and corrective actions when needed.

Product Safety & Environmental Compliance:

All our projectors are designed with user safety and environmental protection in mind. Key features include:

• Over‑temperature and short‑circuit protection – Built‑into the power supply and mainboard to prevent electrical hazards.
• Flame‑retardant enclosures – Using UL‑rated V‑0 or V‑1 materials that self‑extinguish in case of internal fault.
• Energy‑efficient LED light sources – Low power consumption (typical 100‑200W) and long lifespan (up to 30,000 hours), reducing waste and energy costs.
• WEEE compliance – We are registered under the German ElektroG (WEEE-Reg.-No. DE 45173348) and support end‑of‑life recycling of our products in compliance with EU directives.

Third‑Party Testing & Ongoing Compliance:

We regularly submit our products to accredited third‑party laboratories (such as Shenzhen Tongzhou Testing and AZT) for independent testing. Certificates are updated whenever design or component changes occur. We also monitor regulatory updates – for example, changes to RoHS restricted substances, new energy efficiency standards, or updated EMC norms – to ensure our products remain compliant over time. This proactive approach guarantees that our customers receive products that meet the latest legal and market requirements.
