Hybrid Dimming

Hybrid dimming for better light quality

New Helvar drivers have hybrid dimming capabilities which enables good quality light even at 1% – 20% dimming levels. Helvar is constantly developing the range with products that produce high quality light in a dimming range of 1% – 100%. 


How does hybrid dimming work?

Hybrid dimming capable products can be dimmed both on Constant Current Reduction dimming (higher dimming range), and on Pulse Width Modulation dimming (lower dimming range).

 

Constant Current Reduction (CCR) dimming is a very efficient dimming technique for products dimmed only on higher range, e.g. 20% – 100%. On lower range, the current reduction dimming can have a negative impact on the light quality, causing e.g. uneven light output, or colour temperature variation. 

 

Pulse Width Modulation (PWM) dimming provides the best light quality on dimming range from 1% to 20%. With our latest products, the dimming range from 10% to 20% performs on 8 kHz, and the dimming range from 1% to 20% on 1 kHz - 8 kHz, accordingly.
