Guangzhou Show Highlights Chip-on-Board Products

29 June 2015

The Guangzhou International Lighting Exhibition is well-known for its large number of exhibitors. However this year there were some notable western companies that chose not to exhibit. This provided an opportunity for many large local Chinese companies to show off their products in more prominent booth locations.

OPPLE had a very large booth covering over 300 square meters. Its “Snow Crystal” luminaires caught many people’s eye. It consisted of a series of regular hexagon-shaped luminaires that were connected by magnet to create a variety of shapes and sizes. The combined luminaire was controlled using a ZigBee-based control system.

As with other recent industry trade shows, there was a lot of discussion and demonstrations centered around smart lighting, and there was a greater focus on smart homes, rather than smart commercial buildings. There were also some unique user interfaces demonstrated with the control systems, including one panel that used motion and gesture control.

There was also a large presence of chip-on-board (COB) products that focused on light quality and color rendering. Luminus showcased its latest COB series, with high CRI (color rendering index) for commercial applications. Shineon launched its COB-G series of high density products, using ceramic substrate and flip chip technology.
