Especially in office areas, luminaires with a UGR value of less than 19 should be used to avoid disturbing reflections. When determining the UGR value of a complete room, additional factors such as wall colour[s] and surface finishes play a role. UGR VALUE HCL stands for "Human Centric Lighting" and means the simulation of lighting situations according to the biological day-night rhythm of humans. HCL matches artificial light indoors to natural daylight and promotes well-being, mood and health. Numerous DEKO-LIGHT luminaires can already be integrated into an HCL control system to adjust the light colours to the biorhythm. In addition, several LED stripes in different light colours can be combined in one profile and thus integrated into the HCL lighting design. HCL Luminaires that can be dimmed via DALI can be perfectly integrated into lighting/property management systems. The great advantage lies in the wiring: via DALI, all luminaires in a line can be individually addressed and controlled. But this variant is also suitable for individual luminaires: DALI dimmers without an address exist for this purpose, which address the power supply unit directly. The good news: most systems on the market already have DALI interfaces. DALI DIMMABLE DIM TO WARM With the dim-to-warm function, you not only adjust the luminous intensity downwards, but by simultaneously changing the light colour [e.g. from 3000 to 2000 K], you obtain a room mood adapted to the new situation. LED luminaires with dim-to-warm technology can therefore be used particularly flexibly.
