What Prolight opto technology does

ProLight Opto Technology (葳天科技股份有限公司) is a Taiwan-based, publicly listed high-power LED packaging specialist founded in 2004 and headquartered in Zhongli Industrial Park, Taoyuan City, where it operates a 7,000m² manufacturing facility. The company designs and manufactures discrete LED emitters, chip-on-board (COB) modules, CSP packages, Mini LED packages, and UV/IR LED components built on proprietary eutectic bonding technology, KSF phosphor coating, and chip-scale packaging techniques that together deliver differentiated thermal management, color stability, and brightness output (up to 460 lumens single-chip in its third-generation series). Its product portfolio spans six application families: warning-light/automotive LEDs, general and commercial lighting emitters and COBs, UV (UVA/UVB/UVC) and IR LEDs, horticultural plant-growing LEDs with batwing optics, entertainment-lighting COBs and emitters, and architectural/landscape multi-color LEDs — each backed by IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, RoHS, and LM-80 certifications.

The company's go-to-market is sales-led and B2B, with revenue generated through direct sales inquiries ([email protected]), participation in major industry exhibitions including Touch Taiwan and Shanghai ALE, and the provision of both standard catalogue products and small-batch, multi-variety custom ODM/assembly services including light modules and lamp-board assemblies. It operates a regional subsidiary, Shanghai Weizhao Shi Electronics Co., Ltd. (上海葳照世電子有限公司), established in 2011 to serve the China market. Pricing is not publicly disclosed; quotes are handled through the direct sales team.

ProLight completed its IPO on the Taiwan Stock Exchange in 2012, introduced Epistar (晶元光電) as a strategic partner at that time, and became a member of the Ennostar Inc. (富采控股集團) compound semiconductor group in 2021 after Epistar had raised its equity stake to 52.5% via a 2019 private placement. The group integration provides upstream epitaxial wafer and chip supply, while ProLight contributes high-power packaging expertise to the joint LED value chain. The company holds more than 200 patents across Taiwan, the US, China, and Europe and reinvests approximately 10% of annual revenue into new technology development, supporting continued product launches such as the world's first all-inorganic UVC 30-degree spotlight package and the third-generation eutectic-bonded high-power LED series launched in February 2025.
