Professional dimming solutions for a flicker-free environment
What is flicker in LED lighting, and how does it affect us?
Flicker is a rapid fluctuation in light that can be visible or imperceptible to the human eye. This effect is common in LED lighting systems due to how electrical flow interacts with the technology, and typical issues often arise from the choice of materials. A clear example is the incompatibility in frequencies between power supplies, dimmers, and LED systems.
Visible flicker can cause eye strain, affect visual health, and impact the quality of photos or videos, leading to problems with video and photography equipment. Even imperceptible flicker in LEDs, though not visible, can impact visual comfort. In spaces where an optimal environment is desired, avoiding flicker is essential to maximize comfort and prevent these effects.
Dimming is not only about adjusting light intensity; it also allows for blending RGB or RGBW color lights and adjusting Tunable White tones, from cool to warm.
“At Actilum, we ensure continuous and comfortable lighting for all applications.”
Why should dimming in LED technology avoid flicker?
Dimming control in LED technology improves lighting efficiency and flexibility. However, reducing light intensity can sometimes lead to issues such as flicker, increased energy consumption, and shortened lifespan of drivers and the overall system.
This flicker can be bothersome and, over time, can lead to visual health issues, such as increased eye strain.
“At Actilum, we understand that flicker-free dimming enhances the user experience, creating comfortable work environments and living spaces, so we focus on developing flicker-free solutions.”
What are the visible flicker frequencies, and how do they affect people and devices?
Flicker appears at different frequencies, some detectable to the naked eye and others visible only to cameras and devices. Depending on camera quality, flicker can appear as dark bands or interruptions, complicating content creation.
People may also notice visible flicker at frequencies between 3 and 70 Hz and audible flicker up to 20 kHz, which can cause discomfort and distraction.
Actilum’s stable lighting systems for photography and video provide flicker- and noise-free lighting, ideal for people and content recording alike.
What are the audible flicker frequencies, and how do they affect humans and pets?
Some audible flicker frequencies, common in most market products and ranging from 50 to 2000 Hz, generate sounds that, while not always noticeable, can affect people and pets, which are especially sensitive to these noises. Low-quality lighting systems can create a noisy, uncomfortable environment and produce harmonic frequencies that interfere with telecommunications, security alarms in stores, and compliance with regulations.
Actilum’s flicker- and noise-free lighting systems eliminate both visual flicker and noise, providing a disturbance-free environment.
How does flicker impact the environment where LED lighting is used?
Flicker significantly affects the environment. In offices and work areas, flickering light can be distracting, reduce productivity, and cause eye fatigue. In retail spaces, flicker-free lighting creates a more pleasant shopping experience for customers.
Actilum understands that a well-lit, flicker-free environment is essential for any application, from offices to greenhouses.
Why can poor dimming increase flicker?
Poorly designed or low-quality dimming often causes bothersome flicker. These systems fail to properly regulate power flow to the LED, resulting in increased flicker due to poor frequency control practices or low-quality components. Actilum’s flicker-free dimming systems for offices, stores, and other spaces provide precise, flicker-free lighting control.
