Bridgelux, a US-based light-emitting diode technology company reportedly backed by Taiwan Semiconductor, has raised $60.5m.
The latest fundraising was disclosed in an SEC filing, which said Bridgelux is looking to raise $78.6m.
Taiwan Semiconductor is a minority investor with a 4% stake, a Dow Jones VentureWire story in May reported. The latest round was expected to include an investment from an undisclosed investor, the May VentureWire story said.
Last summer, Bridgelux raised $50m and William Watkins, chief executive of Bridgelux, told VentureWire in May the pre-money valuation of the last round was $250m and that the new round had a higher valuation.
Watkins added that Bridgelux had raised $120m in total before the new round from venture capital firms Chrysalix Energy Venture Capital, DCM, El Dorado Ventures, Harris & Harris Group, VantagePoint Venture Partners and VentureTech Alliance.
