LM4X/LMX-DPS User Manual

 

 

Description & Specifications 

The LM4X 4-inch, air-cooled LEDs provide a significant increase in output power needed in large test facilities 

or for fast pressure sensitive paint measurements.  Large test sections require more excitation light because 

the model is further from the data acquisition system and fast PSP systems require significantly shorter 

camera exposure times.  The larger heat sink and higher number of individual LEDs allows the system to be 

driven harder than the 2-inch, air-cooled LED systems, providing ~5 times the output power.  Three parts 

comprise the 4-inch, air-cooled LED: the power supply, the LED module and the umbilical power cable.
