Innovations in Optics has announced high-power white LED light engines for OEM fiberoptic illumination. LumiBright Light Engines couple directly to liquid light guides and fiber bundles with no additional optics. They deliver up to 4,000 lumens into the light guide.
Offering substantial cost and operational advantages, white LEDs are becoming popular light guide illumination sources for many technical applications that were historically dominated by tungsten halogen and HID lamps. LumiBright light engines feature patented technologies that encompass non-imaging optics with chip-on-board (COB) LED arrays on metal core circuit boards to provide both optimum luminous efficacy and ideal thermal management. Unlike the so called “big chip” LEDs used in many light guide illuminators, LumiBright light engines feature large source size and emit into a numerical aperture that matches the acceptance cone angle and diameter of light guide systems. The unique design results in many more lumens emitted from light guides relative to the big chip Lambertian emitters.
The LumiBright 2400B-400-W has a 0.66 numerical aperture (NA) and illuminates fiber bundles and light guides sized from 6.0 to 8.0 mm in diameter. Well suited for applications in machine vision and remote source illumination, the light engine generates up to 4,000 lumens. The 2400B-500-W is ideally suited for endoscope and microscope illuminator applications with a 0.60 NA for light guides that are 3.0 to 5.0 mm in diameter. The 2400B-500-W produces up to 1,500 lumens. Available light engine system accessories include thermal management devices, wire harnesses, and driver/controllers.
