LED Breakthrough
.

Digital cameras see LED light differently than tungsten/daylight sources. Additionally cameras interpret these light sources differently from each other. Color temperature meters are unable to see the full spectrum and therefore do not work for the evaluation of LED light. Samples are only taken in three or four places of the spectrum (narrow band filters). Spectrum analysis and CRI values offer a serious step for evaluation, but usually do not include colors called R9, which is a very important and critical red value, and R13 – skin tone. Even expanded CRI evaluations do not offer reliable criteria.TLCI (Television Lighting Consistency Index), the new standard of the European Broadcasting Union (EBU), offers a better and more reliable base for the way studio cameras see LED light. These studio cameras usually work with three CCD sensors. Thus, the results are not really indicative for the way different CMOS cameras see LED color. Only practical tests with many different cameras and shooting different skin tones in reference light comparisons bring us closer to the target.

dedocolor
dedocolor finally offers values and properties which bring us very close to the target, even under critical conditions, and even in most mixed light situations..

LED Breakthrough. Expanded spectrum analyses
Measurements with our 40W DLED4.1 bicolor light in tungsten function

LED Breakthrough - 2

Values gained from expanded CRI measurements with our 40W DLED4.1 bicolor light in tungsten function.

Focusing LED lights present special challenges regarding color distribution. Specially developed LED light sources in combination with our patented double-aspheric technology (recognized by the Oscar committee for Technical Achievement) have allowed us to provide five different dedolight DLED focusing LED light fixtures. All deliver perfect light distribution, the widest focusing range in the industry and allow the use of our unique line of light shaping accessories.

  • Available in daylight, tungsten and bicolor. Bicolor is variable from 2700K to 6500K
  • Passive cooling – no fan, no noise – for all of our focusing LED lights from 8W to 90W
  • Active Cooling with our DLED12.1 (250 W) – probably the most quiet solution.

Health hazards
In the past with metal halide lamps the hazard was with the short wave – length ultraviolet, possibly causing skin cancer and cataract.

In this field we have always offered the worldwide lowest and safest uv-value. With LED light sources an additional hazard can be found, caused by the unavoidable blue peak. New criteria have to be applied as in bio-hazard standard EN6247.

Our products comply with the requirements of bio-hazard standard EN6247 in the category of “exempt” (without any health hazard criteria).
