How Vantage Does Human-Centric Lighting: Sun as a ‘Phantom Load’
To incorporate circadian lighting into a Vantage control system, simply add the "sun" object as a phantom load into the Design Center programming, and lighting will sync to the sun's natural intensity and color temperature for any given geography and time.
How do you add circadian algorithms to your lighting-control system? Simple. Add the sun to your programming environment.
That’s basically how Vantage Controls, a Legrand company, helps integrators implement human-centric lighting without complex calculations. Vantage has the algorithms figured out to create a virtual sun for any geographical location at any given time. Press the “sync” button on a Vantage keypad, and the lights turn automatically to the brightness and color temperature of the current natural daylight conditions.
In Vantage’s Design Center programming environment, the “sun” serves as a phantom load, setting light schedules based upon “true day length,” says Vantage product manager Mark Moody. “We consider the natural path of the sun – that’s the phantom load. It’s a bunch of programming that the dealer doesn’t need to do.”
Of course, humans these days don’t schedule their activities based on the sun’s natural path … not since Thomas Edison brought us artificial light.
Vantage accommodates real-world living by allowing users to shift or extend the “sun’s natural path.” A workout scene, for example, might have the virtual sunrise begin at 4:00 a.m. instead of 6:48 a.m., prematurely ramping up the lights’ intensity and color temperature to suit the early-morning workout.
A homework setting might extend the astronomical clock by a couple of hours, beginning the sunset emulation – dimming the lights and warming the hue – after the real-life sun has set.
Vantage has a partnership with Lumenetix, a leading supplier for LED drivers for several popular luminaire manufacturers. Vantage control systems can accurately render the color and other lighting characteristics of any tunable fixture with a Lumenetix Araya5 LED engine.
