Mentor Graphics announced a new release of its T3Ster and TeraLED measurement and characterization hardware, as well as in FloEFD software simulation products, to meet the needs of lighting developers using arrays of LEDs in headlights, taillights and other transportation industry applications. According to the company, these upgrades enable developers to efficiently manage the heat and condensation developed by these arrays, improving product reliability and life. In addition, with T3Ster and TeraLED hardware's ability to measure both thermal and optical characteristics of single LEDs and full arrays, proper light quality and color can be achieved.
The FloEFD product has been extended with a dedicated LED module which enables thermal simulation of the most advanced LED products, along with the capability of predicting their "hot lumens," i.e., their total emitted luminous flux at their operating temperatures. This capability is provided through an LED model library whose elements are characterized directly from physical tests by the Mentor T3Ster+TeraLED combined thermal and radiometric/photometric LED testing solution. In addition, the FloEFD LED models support radiation absorption in semi-transparent solids, such as the head or taillight lens.
LED arrays are becoming larger and to accommodate these larger arrays, Mentor now provides a 50cm diameter sphere, in addition to its 30cm sphere, on the TeraLED product to measure optical performance.
