Features

  • LED Array Comprised of 20 High Brightness LEDs
  • Longer Lifetime than Traditional Light Sources (up to 100,000 hours)
  • Fits Many Commercially Available Camera Illumination Units
  • Compatible with Thorlabs' 30 mm Cage System
  • LED Array Power Supply Sold Separately (See Below)

Thorlabs' LED Array Light Sources consist of 20 individual bright LEDs and are available with one of seven central wavelengths between 365 nm and 850 nm or with a broadband, cold-white output (see the graph below for the available emission spectra). Each array features a diffuser mounted over the LEDs and secured by the housing. The intensities of these LED arrays range from 0.26 mW/cm² to 4.0 mW/cm², as measured from 100 mm away along the emission axis.

Conveniently mounted in a Ø1.5" housing, these light sources can be used for a variety of lighting applications. The housing can be readily secured into most optical mounts used in camera illumination units. Additional mounting options include two threaded holes on the rear of the housing, one M4 and one 8-32 (see drawing below), as well as grooves running the length of the housing that allow the LED unit to be placed in a 30 mm cage system. The LED unit will be suspended by the cage rods but not restrained from moving along the optical axis of the cage system as shown in the photo below and to the right. To fix the position of the LED unit, clamp it between two fixed cage elements (see the Application Idea tab for more details). Thorlabs also offers a mounting adapter (Item # AD38) for these LEDs to be mounted in our Ø2" mirror mounts, such as the KS2 shown above.

These LED arrays are only compatible with the 24 V LIU-PS power supply, which must be purchased separately. The LED arrays sold on this page are not compatible with Thorlabs' LED current controllers.

Please Note: During normal operation, the temperature of the LED housing can increase by as much as 25 °C above the ambient temperature. Avoid handling the LED housing while the LED is on or shortly after it has been turned off.

Dichroic Filters and Filter Wheel for Multi-Color Light Source

The image below and to the left shows the LIUCWHA white LED array being inserted between the 30 mm cage rods. The LED is sandwiched between a CFW6 30 mm Cage Filter Wheel and a CP03 30 mm Cage Plate so that it cannot slide along the cage rods. The Ø35 mm aperture of the CP03 cage plate allows for easy access to the power terminal located on the rear of the unit. The photo below and to the right shows the completed assembly.

In this application, the CFW6 was loaded with Ø1" dichroic filters (FD1R Red Filter, FD1G Green Filter, FD1B Blue Filter, FD1M Magenta Filter, FD1Y Yellow Filter, and FD1C Cyan Filter). When combined with the white LED array, the user can illuminate the sample, object, or subject with any of the primary or secondary colors by simply rotating the filter wheel.

For automated applications, the CFW6 can be replaced with either a FW102C or FW103H motorized filter wheel. In addition, these LED arrays can be mounted to any SM1-threaded (1.035"-40) motorized filter wheel that is not cage compatible by using 30 mm cage rods, an SM1T2 coupler, and a CP02 cage plate.

Purchased LIU525A and within 20 hours, some of the LEDs were out. We were able to return the unit and get a replacement (with some hesitation from thorlabs). The second unit eventually lost some LEDs, too! For a $200+ unit, I would expect it to last much longer. Therefore, we won't be purchasing any more array lights.

A response from Julien at Thorlabs: We are very sorry about the difficulty you have experienced with this product. The repeated issues you have been having are extremely unlikely. The return and failure rates for the LUI line is very low. We will contact you directly to further discuss the exact environmental parameters in your set up to see if maybe a root cause for the failures can be found there and work out a specific solution.

Is it possible to operate 4 LIU104 light sources all at the same time using the DC4100 LED controller and breakout box?
tschalk  (posted 2014-01-09 03:57:37.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The Arrays are equipped with an integrated circuit which drive the individual LEDs and an additional 24V power supply for the whole array is needed. It is not possible to drive the LED Array with our LED drivers and control, for example, the brightness of the LEDs. Please contact me at europe@thorlabs.com if you need any further information.

Hello, I was hoping you could suggest which type of safety glasses filter material would be suitable with use for these products? Thankyou
jlow  (posted 2013-09-11 09:03:00.0)
Response from Jeremy at Thorlabs: We will contact you regarding this. You can contact a local office to discuss about your applications in the future. Our contact information is provided at http://www.thorlabs.com/locations.cfm.
nicolas.beaugerard  (posted 2013-06-28 12:14:51.117)
Hello, I would like to know how to control the LED brightness. I guess that I need to add a potentiometer between the pin 2 and the ground. Is that's corect? More over, what resistivity do you recommend ?
tschalk  (posted 2013-07-03 08:06:00.0)
This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. A typical control unit is shown in the manual of the LED Array: http://www.thorlabs.de/Thorcat/16000/LIU004-Manual.pdf. The LED brightness can be controlled by a variable controlled current device. The maximum current for the LED Array is 120mA. I will contact you directly for more detailed information.
jvigroux  (posted 2012-10-11 12:43:00.0)
A response from Julien at Thorlabs: Thank you for question! There is no need to add an extra resistor. The LIU are designed to work with 24V input voltage and as such there is already a input resistor to ensure that the current through the LED is correct for this voltage
user  (posted 2012-10-11 06:59:35.487)
I need to clarify the example circuit in the manual. Do we need to add a load resistor in series with a 24V PSU to fix the current to max intensity or does the LIU004 have this already. we do not want to connect a pSU directly to this if it unprotected.
jvigroux  (posted 2012-07-11 07:28:00.0)
a response from Julien at Thorlabs: thank you for your inquiry. The weight of the LIU004 is about 96 grams.
joseph.hampton  (posted 2012-07-10 13:13:04.0)
Hello, do you know the approximate mass of LIU004? cheers!
jvigroux  (posted 2012-06-20 08:21:00.0)
A response from Julien at Thorlabs: Thank you for your feedback! In principle, the LED should indeed work with no optical power reduction for the specified time. The specified time is however valid only for the conditions it was tested in (temperature, voltage, voltage and current stability...). I will contact you to discuss the way the LED was used and see if there is maybe an external factor that could have precipitated the degradation of the LED. If not, we would of course exchange the LED within the warranty.
david.lee  (posted 2012-06-18 10:10:23.0)
The stated operating lifetime for the LIU004 LED light source is up to 100,000 hours which is approximately 11 years. We have two of these units, both operating with the LIU-PS power supply. On one unit 10 of the LEDs have failed. On the second unit many of the LEDs now have significantly lower brightness than the brightest LED causing the source appear highly non-uniform. I suspect the dim LEDs will fail soon. Both units have only been operated for approximately 1,000 hours. Is LED lifetime a known issue? Could we improve the LED lifetime by operating at a lower power? Any comments regarding improving the lifetime would be appreciated.
jvigroux  (posted 2011-12-08 10:20:00.0)
A response from Julien at Thorlabs: Unfortunately the compliance voltage of the LEDD1B is around 12V while the required forward voltage for the LIU001 is 24V. The LEDD1B is meant to be use primarily with our high power mounted LEDs. The most suited adjustable LED driver for the LIU00X would be the DC2100 due to its high compliance voltage.
jripoll  (posted 2011-12-07 08:22:51.0)
Dear Sirs, Can the LIU001 be used with the LEDD1B to regulate its intensity? Thanks and best regards, Jorge

A response from Ken at Thorlabs to mhyde5: Unfortunately, we are unable to offer an LED light source at 1550nm at this time.
mhyde5  (posted 2009-10-16 10:39:32.0)
I see in the comments below that you were able to construct an LED light source at 780 nm. I was wondering if you could construct one at 1550 nm? I have 5 of your unmounted 1550 nm LEDs; however, they do not provide enough light for my application. Milo Hyde
Greg  (posted 2009-04-06 09:29:00.0)
An update from Greg at Thorlabs to jcheng: After talking with colleagues further, we have found that we are able to offer an LIU series LED source at 780 nm. Please let me know via e-mail or contact Technical Support if you are still interested in such a unit.
