Eye Response Dimming
The human eye has a non-linear response to the brightness of light. The adaptation of our pupils to bright light greatly differs when being in a darker environment. It is scientifically proven that this is a logarithmically response. ELR LED drivers provide dimming curves to match the human eye response for maximum comfort and a luxurious feeling of the dimming effect.
Smooth Dim-to-off and No “Pop-On”
Our eyes are very sensitive to dark conditions; we can see objects even in dim moonlight. A slight change of brightness level in the dark can be very noticeable to the human eye. As ELR focus to provide the best comfort of light and dimming experience to our customers, our luminaires are designed to have a smooth dimming transition from 100% brightness to 0.1%, and from 0.1% smoothly dim to completely light off. Vice versa, from completely light off to on, the transition is smoothen out to light up gradually with a similar effect to sunrise. We call it the smooth dim-to-off and no “pop-on” effect.
ComfyEYE – Reduced Flicker Percentage
Light oscillates, but normally at very high frequencies not noticeable by the human eye. Therefore our instantaneous perception is a continuous ray of light. Just like TV or computer screens having their own defined oscillating refresh rate, otherwise known as frame rate. Nowadays with our power grid running at 50Hz or 60Hz, artificial light is prone to oscillate at 100Hz or 120Hz. Since this oscillation frequency is low, it’s easier for the human eye to perceive a stroboscopic effect that may cause discomfort and health concerns to some.
In order to provide comfortable light experience, the ComfyEYE aspect embedded in ELR LED driver technology minimises light flicker percentage, which is the measurement of peak-to-peak contrast of light output. By reducing light flicker percentage below certain threshold at lower frequencies, ComfyEYE eliminates stroboscopic effect and prevents our eyes from being strained to perceive light as continuous.
Multiple Dimming Protocols
ELR provide LED driver selections with different dimming protocols to fit different applications.
