TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has developed a compact and highly luminous optical module for LED headlights using a unique system that simply combines a converging lens and projecting lens for more efficient LED headlights. Even though the new system measures only 20 millimeters high it achieves 180 percent luminous efficiency, which is equivalent to larger 40 millimeters to 60 millimeters projecting lenses. Optimal light-distribution control and design flexibility enhance driving safety and ease while lowering energy consumption, making the module an ideal solution for next-generation smart mobility. The new technology will be exhibited at the Mitsubishi Electric booth during CES Asia 2018 in Shanghai, China from June 13 to 15.
Headlight optical systems collect light projected from an LED light source to form a light beam with a cutoff line for the low beam. Conventional systems use reflectors with coated mirrors that are prone to reflection loss, low efficiency and take up space due to their large size. Mitsubishi Electric, aiming to enhance night-driving safety by achieving superior visibility for the driver and the elimination of glare for other vehicles and pedestrians, has developed an optical module for LED headlights that is compact, highly luminous-efficient, equipped with advanced and precise beam-control functions, and offers design flexibility.
1) Direct projection for compactness and high luminous efficiency
- Unique optical system for LED light source convergence and projection.
- Compact 20mm high design incorporates no mirror.
- 180% luminous efficacy equivalent to that of larger 40mm–60mm projectors.
- Compactness and high luminous efficacy achieve design flexibility, resulting in diverse thin-, multiple- and single-light options for motorcycles and automobiles.
2) Effective beam control for enhanced ease of driving and safety
- Sensor detects pedestrians and illuminates them with a spot beam to compensate for low-beam lights.
- Color temperature can be adjusted for the driver’s nighttime color visibility.
- Adaptive Driving Beam (ADB) by precise beam-control functions.
