Page 3: Important Safety Instructions
Ear 15. Wear appropriate safety glasses at all times. ISSI recommends UVEX SCT Orange lenses. Safety glasses plugs or protectors in the ear canals or over the ears must be worn when operating the utilizing these lenses block near 100% of the damaging retinal blue light. -
Page 4: Welcome
LM2XX/DC2XX User Manual Welcome Thank you for purchasing the water-cooled LED system. We hope it exceeds your expectations for experimental testing. LM2XX-XXX DC2XX UM2XX-10 The first section of this user manual serves as a quick-start guide to getting the LED system set up. The remaining pages describe the hardware side of things in more detail, and is intended to be used a reference. -
Page 5: Led Illumination Lamps
Optical measurement techniques require a sufficiently energetic, low noise, stable illumination source if quality data is to be acquired. Any variation in output illumination from the excitation source will cause measurement errors. ISSI LED arrays contain proprietary optical and electrical filtering to achieve very stable, narrow-band illumination. -
Page 6: Description & Specifications
LM2XX/DC2XX User Manual Description & Specifications Water-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. -
Page 7: Operating Instructions
LM2XX/DC2XX User Manual Operating Instructions The water-cooled LED system is designed to be easy to set up and operate. There are only three parts of the water-cooled LED system. They consist of the LED module, driver module, and the umbilical cable. The umbilical cable is connected from the power supply to the LED module. -
Page 8: Dc2Xx Led Driver Module
LM2XX/DC2XX User Manual DC2XX Driver Module Front Panel The front of the drive module has the input water connections on the right side of the panel. The input and output are marked accordingly and must be adhered to because there is a flow meter inside the drive box that needs to have the water flowing in the proper direction for correct operation. - Page 9 LM2XX/DC2XX User Manual Status Indicators Hi Temp – LED heat sink temperature too high, LED will stop emitting Low Flow – Flow rate of cooling water to the driver module is too low Open RTD – Umbilical cable RTD not connected Duty Factor - No longer used.
- Page 10 LM2XX/DC2XX User Manual Water Fittings Cooling water is supplied to the DC2XX Driver Module via brass quick-disconnect fittings. These fittings are designed to click and lock together with their mating connector, providing a water-tight connection. The input and output are marked accordingly and must be adhered to because there is a flow meter inside the drive box that needs to have the water flowing in the proper direction for correct operation.

Page 11: Rear Panel
LM2XX/DC2XX User Manual Rear Panel The rear panel contains the water connections to the LED lamp head and a large connector with the electrical connections (power/trigger) to the LED module. The AC input along with the fusing for the electrical input on the rear center of the drive module are also located here. - Page 12 LM2XX/DC2XX User Manual Caution: Do not use any other means to connect to the LM2XX modules other than the cables provided. If you believe you require a different length or cable configuration for your application, please consult the manufacturer. The connectors are keyed to prevent improper insertion, and are locked in place by a clockwise twist lock mechanism.
- Page 13 LM2XX/DC2XX User Manual AC Power AC input power to the DC3X is provided via the IEC C14 power inlet connector to the right on the rear panel. A power cord has been provided. Do not substitute the provided cable. If you require a replacement cable, please consult the manufacturer.
- Page 14 LM2XX/DC2XX User Manual Air Vents There are two fan ports on the rear that should remain clear of obstructions at all times. One draws air into the drive module while the other provides an exhaust to the atmosphere. Cooling Flow Inlet for Power Supply If the LED system is operating in a low static pressure environment, it is best to place the driver module outside of this in a more climate controlled are if possible.

Page 15: Lm2Xx Led Module
The LM2XX LED module is a special purpose LED light source that is specifically designed to provide the optimal illumination source for all pressure sensitive paint applications using ISSI proprietary paint formulations. The unit has two connectors on the rear cover of the housing, one circular connector for electrical connections and two quick-disconnect water fittings for cooling. - Page 16 LM2XX/DC2XX User Manual The multi-pin circular connector at the top of LM2XX rear cover supplies DC power to the integrated LED array. Also provided is the temperature feedback to the DC2XX for the purpose of over-temperature protection. Cooling for the LM2XX is provided via the two quick-disconnect water fittings on the bottom of the rear cover.

Page 17: Electronics And Cooling Cable
LM2XX/DC2XX User Manual Electronics and Cooling Umbilical Cable Each LM2XX connects to the DC2XX via an umbilical cable which provides power and trigger to the LM2XX as well as cooling water to the LED module. Connections can only be made one way so the cable cannot be incorrectly installed. -
Page 18: Cooling Water Requirements
LM2XX/DC2XX User Manual Cooling Water Requirements To provide proper cooling water to the driver module, the LED system needs to be connected to either a clean tap water source or a refrigerated chiller. The refrigerated chiller must have the proper pump capacity (positive displacement pump) to provide cooling water. -
Page 19: Setup Examples
LM2XX/DC2XX User Manual Setup Examples Multiple LED systems can be connected to a single chiller using a manifold system (sold separately) as long as the chiller or water source has sufficient capacity for the number of LED systems to be connected. -
Page 20: Accessories
LM2XX/DC2XX User Manual Accessories LM2X Clamp (LM2X-CL) The LM2X-CL is an optional accessory for the LM2XX that securely clamps to the LED housing for extra grip during mounting. It is compatible with the SL20 ball mount base from Thorlabs. This is a strongly recommended accessory as it makes mounting much faster and adjusting the LED position much easier than a single threaded hole and post method. - Page 21 In areas where more light is needed on a surface, the parabolic reflector and diffuser can be used on any LM2 series LED to narrow the output angle from 120-degrees down to 40-degrees. This reflector also uses a diffuser for a more uniform output from the LED module. The reflector and diffuser is simply screwed onto the front of the filter housing of the LED module.

LM2XX/DC2XX User Manual Typical Waveforms Note: Other wavelengths are available upon request. Cost and output power may vary from the standard depending on the wavelength. -
Page 23: Maintenance
LM2XX/DC2XX User Manual Maintenance In the case of a broken glass filter, it can be removed and easily replaced with a new one. Using the provided spanner wrench tool, the damaged filter can be removed from the filter housing. Turn the wrench counter-clockwise as shown below to remove the filter. - Page 24 LM2XX/DC2XX User Manual A small retaining ring holds the glass filter in place. The spanner wrench removes this ring and then the filter can be removed. Once the old filter has been removed, carefully place a new one in the filter housing and reattach the retaining ring using the spanner wrench and turning clockwise until tight.
