Luminar was a LiDAR sensor and software company focused on automotive safety and autonomous driving. Its core product was the Iris LiDAR sensor, which used laser pulses to build real-time 3D maps of a vehicle's surroundings, with detection range up to 600 meters. Luminar began series production of Iris in April 2024 for the Volvo EX90, its primary production customer. The company was also developing a next-generation sensor, Luminar Halo, and had active development contracts with OEMs including Nissan and Mercedes-Benz. Luminar sold primarily to automotive OEMs through multi-year development agreements intended to convert into series production contracts, and also sold to commercial trucking, defense, and industrial customers. Revenue came from sensor sales, non-recurring engineering fees from development contracts, and photonic components sold through its semiconductor subsidiary, Luminar Semiconductor (LSI). LSI developed lasers, detectors, and ASICs serving aerospace, defense, industrial, and medical markets, and generated roughly one-third of Luminar's revenue. Luminar's path to profitability depended on achieving scale — it sold each sensor below its cost of production, and positive unit economics required high production volumes that Volvo never delivered. Luminar filed for Chapter 11 bankruptcy in December 2025 and sold substantially all of its assets by February 2026. LSI was sold to QCi for $110M and represented the most valuable asset in the bankruptcy process.
