Seen this in many houses, people upgrade their lighting setup and install a dimmer. Which works. But usually it also makes the lights flicker unintentionally, which is super annoying IMO.
Now, my understanding of electrical engineering is pretty rudimentary so I’d appreciate more something that explains the concept in a way that Cavewoman Mothra can understand rather than something technically accurate.
Thanks
That’s not the only way to dim an LED, just the cheapest. Variable current power regulators are the premium option.
A screw-in LED bulb combines LEDs and power regulating electronics. Some of them handle the variable input voltage a household dimmer provides gracefully, but that’s more expensive.
Hanging the current Chan change the hue of the led. In some cases it’s okay in some cases it isn’t. Cinéma lights for instance don’t dim with voltage because of that. Instead they have 3 separate drivers synchronized to dim in a canon. One after the other so that there is always the same number of LEDs on at all time regardless of the dimmer level.
That’s true. Describing current regulation as the premium option was an oversimplification. For household lighting, it’s usually the premium option.
Not always true. For example, digital Sputnik lights utilize current control dimming. This different type of dimming allows them to work in super high speed footage due to having very little or even no perceivable flicker.
That’s awesome! I love how deep we are going with this! I have to admit I don’t k or as much about cinema lighting as I know about cameras and Steadicam.
I’m happy to share any experiences I have had as we’re likely the only two filmmakers in the whole fediverse right now!
