08 Dec 2008 Efficient forward flux measurement method in half the footprint This intuitively designed system allows for the same accurate, repeatable results as a traditional integrating sphere system in half the footprint. Designed to measure forward emitting lamps, LEDs, board mounted and heat-sinked LED Light Engines for Solid State Lighting (SSL), the HalfMoon System features a Spectraflect® coated hemisphere capped with an interior mirrored surface. This mirrored surface creates a virtual integrating sphere within the interior. A centrally placed port in the mirrored surface allows for the Device Under Test (DUT) to be internally mounted in the center of the virtual sphere while keeping the electrical and thermal controls of the DUT outside, reducing absorption errors that can occur in
a traditional sphere based system. |
