Guangzhou Haoyang Electronic Co Ltd

Guangzhou Haoyang Electronic Co Ltd, also known by its brand name Golden Sea, is a Chinese high-tech enterprise founded on March 17, 2005, and headquartered in Guangzhou, China. The company is publicly listed on the ChiNext Board of the Shenzhen Stock Exchange under the ticker symbol 300833.SZ. As of 2024-2026, Guangzhou Haoyang Electronic employs over 1,600 staff and reported a revenue of approximately 1.11 billion CNY in the last 12 months (as of April 28, 2026), with a market capitalization around 4.82 billion CNY.

The company specializes in the research, development, manufacturing, and global sales of professional lighting equipment and related products. Its main product lines include stage entertainment lighting under brands like TERBLY (LED and HID professional stage lighting, SMART series, laser series), and AYRTON (a French subsidiary offering high-end performing arts lighting). They also produce architectural lighting under the GSARC brand, offering outdoor projectors, wall washer lights, and in-ground lights, and manufacture truss systems via the WTC brand. These products are widely used in large-scale events, theaters, television studios, and urban landscape projects. Guangzhou Haoyang Electronic also acquired SGM Light, a Denmark-based manufacturer of entertainment and architectural lighting solutions, in September 2024.

Guangzhou Haoyang Electronic Co Ltd currently has a limited patent litigation profile in our database, appearing in one tracked case as a defendant and zero as a plaintiff. This posture suggests the company operates primarily as an operating entity that defends against intellectual property challenges.

The sole tracked case, ROBE LIGHTING S.R.O. v. Guangzhou Haoyang Electronic Co Ltd, initiated in June 2025, is a Patent Trial and Appeal Board (PTAB) proceeding before the U.S. Patent and Trademark Office. This indicates a dispute concerning the validity of a patent, likely related to their professional lighting technologies.
