Evolutionary LED lighting for high-speed imaging
A new LED lighting system has been developed by Munich based MESSRING, and the company says the system can deliver 200% more luminous flux than others systems on the same connected load.
The company describe the M=LIGHT Evo as a real quantum leap for efficient illumination and film documentation of crash testing. Indeed, MESSRING has succeeded in doubling the light output of the M=LIGHT Evo compared to its proven predecessor. With a connected load of 1,150W, the 48 highly efficient LEDs provide a luminous flux output of 120,000 lumens in standard mode and can be increased to up to 260,000 lumens in flash mode. All this at a constant power input and available in continuous operation.
As a rule, for different crash test scenarios, areas between 8 and 24 m² must achieve an average illuminance of approx. 100,000 to 120,000 lux to meet the extremely short shutter speeds of high-speed cameras for high-quality recordings. With the new generation of M=LIGHT, it can ensure powerful and flicker-free lighting with daylight colour temperature, with significantly fewer lamps. Moreover, in flash mode, the M=LIGHT Evo unleashes its full power; the microsecond-accurate flash frequencies with up to 25,000 fps - are stepless adjustable between 20 and 500 μs and deliver even more than double the light output in the peak ranges.
Thanks to the synchronization of the lamp and camera shutter, light is available precisely when needed. This ensures consistent exposure of images even at high frame rates.
"LED lighting has become the industry standard when it comes to high-speed imaging, and the advantages over tungsten and gas discharge lamps are clear:
immediately available and controllable light output with no warm-up and cool-down phases, no heat radiation to the test object, and 24/7 available performance," states Wolfgang Rohleder, Head of Sales at MESSRING GmbH, and further explains "The appropriate illumination allows to utilize the potential of modern cameras fully and to deliver better images. Developers thus gain valuable insights for the further development of safety solutions. The M=LIGHT Evo unlocks a new level in this segment. We paved the way with the first M=LIGHT LED almost ten years ago, and now we are taking the next step by again offering a future-proof premium solution for crash facility operators worldwide."
Modular and compatible The M=LIGHT Evo is available with beam angles of 37°, 56° and 71° and can be adapted to a wide variety of facility situations and applications. Optimum lighting intensity is always feasible, whether large-area car-to-car tests involving large lamp groups on movable light frames or airbag deployment tests with a smaller test setup, thanks to the modular connectivity using the daisy chain method. In addition, the M=LIGH T Evo is fully compatible with the predecessor model M=LIGH T LED.
