Particle Shadow Velocimetry LEDLM2X-DMHP-RGB

(Product ID: LM2X-DMHP-RGB)

The LM2X-DMHP-RGB is a 2-inch, air-cooled LED light source that provides three-color (Red, Green, and Blue) outputs.  This LED is used for Particle Shadow Velocimetry (PSV) to illuminate small seed particles in a flow field to measure velocity and particle density.  The LM2X-DMHP-RGB has three BNC inputs to control the timing and pulse width of each of the output colors from an external pulse generator.  The pulsed LED operation is controlled by applying a TTL voltage to the external BNC(s) on the module.  The rise time is less than 200-ns and the fall time is less than 100-ns and the duty cycle is 5%.  The light distribution from the unit is approximately Gaussian for distance greater than 18 inches from the source.  The LED is recommended for use with the PSG-3 pulse delay generator as part of a PSV system.
