Sensing that I was getting retinal damage driving at night, I wondered if I was developing cataracts. My optometrist assured me that was not the case, so I started flashing people to dim their high beams, only to find that their high beams were even brighter. Eventually, I figured out […]
You have been given a lot of misinformation by Mr. Baker in regards to the physics of LEDs.
In particular this description:
“They are also designed to emit a directional beam of
focused light which does not disperse gently over distance, so even from far away,
LED light is extremely intense. LED light is exceedingly dense in the middle of the
beam, but the density is near zero at the edges. This is referred to as “spatial nonuniformity of energy,” where more energy is emitted in the center of the light beam
than the wider and edge areas. Traditional light sources radiate the light outward
and it is dispersed more broadly.”
Mark has had repeated explanations from actual lighting scientists and physicists indicating that he is fraudulently mis-representing the physics of LEDs along with detailed explanations of why and he has refused to alter his message. He accuses the government of fraud when dealing with LEDs, yet he does the same to further his cause. Now I see that you are helping him to continue to propagate this scientifically inaccurate description that he willingly deceives people with.
LEDs could not be different in the way that he describes for numerous reasons and they differ in their light emission physics only in that they emit from one surface of the semiconductor chip into a hemisphere because the photons going backwards are blocked by the construction of the LED package. A filament source radiates into an entire sphere because there is nothing blocking the emission into the sphere, but the light emission pattern of the forward hemispheres between and LED and the filament are substantially similar and not “directional and concentrated”. This is very easy to verify by simply lighting up a bare LED and a bare filament source (preferably with similar lumen ratings) in a room at a distance away from a wall and observing the light pattern on the wall from the LED and the filament. To the eye, the patterns on the wall will look substantially similar and there will be no “central concentration” as Mark continues to claim and scare the public fraudulently with.
Thank you for noticing and writing about this. LED lights are too bright, too white, too glaring.
