LED daylight lighting unit with thermo-management, consisting of two light banks for even and soft illumination.

The efficiency of LEDs is much higher than that of conventional light sources. However, because LEDs also convert energy into heat, a thermal management system is necessary for optimal reproducibility, as otherwise both brightness and color temperature would change as the temperature rises.

The integrated thermo-management ensures that the adjusted brightness as well as the color temperature always remain constant, regardless of the room and unit temperature, thus achieving reproducible results. In addition, the LEDs have a longer service life.

This thermo-management includes both sensor-controlled temperature monitoring with dynamic compensation control and elaborate passive cooling via LED board and aluminum housing.

Each light equipped with 192 selected white SMD LEDs, 5600 Kelvin, CRI = 95. Emitted light has absolutely no IR and UV content, is flicker free without residual ripple. Lights can be dimmed separately or synchronously in 1 %-steps from 10 % up to 100 %. Illuminated info screen.

The light intensity of the two LED panels is matched to each other. This results in precisely homogeneous illumination with symmetrical alignment of the two light banks.

Memory function: The copy lighting starts with the brightness that was set before the last switch-off.

Lamp housings made of sturdy anodized aluminum section, can be swiveled, shifted and adjusted in height. Detachable soft screens. Vertical arms with height markings, tiltable with detents. Mounted with strong cast aluminum clamp bases, clamp width up to 48 mm (1.9 in.). Comes with mains adapter.
