It is interesting that in case of RGBW LED strips I found the flickering more noticeable on the color channels than on the WW, but this has either something to do with the response of phosphor coating that converts the blue emitted light to the white or warm white, human eye sensitivity to the given wavelengths, or combination of these factors. In my experience the frequency they have chosen is a bit too low, causing unwanted stroboscopic effect. Now back to the Loxone dimmers for a moment again. PWM flickering causing stroboscopic effect At ultra high frequencies the system would practically act as an transmitter creating electromagnetic interference all around the house. How about some upper frequency limitations? It is usually limited by the micro-controller maximum frequency, switching transistor energy efficiencies at higher speeds, and potential audible noise in the human sound spectrum. Some sources report that 300Hz is a frequency minimum for stationary and 1kHz for moving flicker free. ![]() It is more recognizable when subject or object is in motion, and in peripheral view where the sensitivity is improved. It depends entirely on the application and human eye natural sensitivity to flicker. While some do not notice flicker at 25Hz (cinema movie frame rate) or lower, others might be irritated by 100Hz refresh or higher. PWM flickeringĭifferent people do have different sensitivity to flickering. Although there were some rumours about the possibility to adjust the PWM frequency, in the end it seems it was not possible. According to the documentation, Loxone has set the PWM frequency to 123Hz. But the thing here is flickering, which is often being discussed in relation with PWM dimming in general. They have very small space requirements in the cabinet on the DIN rail, and offer four channels at 2.1 Amps each (50W per dimming channel). I still have 6 of these since the very beginning of my Loxone installation, and I never had any technical issue with these. Before we jump right into it, let me tell you few things about the former Loxone 24V DMX dimmers. Same happened to EnOcean products while ago.īut there might be other reasons why to look for other 24V dimmers as well. The focus has moved towards Tree and Air products, leaving open standards aside. ![]() Just a simple query to their web-shop reveals that there are no 24V DMX Dimmers any longer. Hi- lume 1% A versatile LED driver available for any control type in applications up to 40W.Some of you might already noticed that Loxone silently discontinued few products and one of the areas impacted are DMX products.
