Before becoming enraged about this, please read on. Volvo is putting artificial suns in their EX90 electric SUV. The sheer outrageousness of this statement can only be surpassed by the carmaker's ingenuity. The company is the first automobile manufacturer to install sunlight-like LEDs for ambient illumination.
The blunt question is, "What’s the catch since the sun lights the cabin through the windows?" Not during the night, not with an overcast, and not where it doesn't shine. This is how things are for most of the year in the Scandinavian peninsula.
What's the connection to the aforementioned doping simile? According to the Seoul-based company (which cites a Harvard Medical School study), light is addictive. Not like "I just have to have that B-body Mopar"-addictive, but serious narcotics-level addictive.
The prestigious University is referring to the light produced by the Sun, which triggers mammalian organisms (humans included) to secrete a "powerful drug." It's called beta-endorphin, a substance similar to an opioid. It has a "strong analgesic effect and addictive ability in addition to making us feel pleasure."
In other words, when someone enters the SunLike-equipped Volvo, the interior light will have the same effect on the body as sunrays (play the video to see what the Swedes mean). We all know – or should know by now! – how screen time exposure negatively impacts us.
Regarding light, the amount of its blue spectrum and the unnoticeable – but very harmful – flickering get us. Most LEDs emit very high-frequency bursts of light, not a continuous beam – like a candle, bonfire, or Sun. Seoul Semiconductors claims their product is the next best thing to that giant fiery globe that lights up our days.
