They also think bright = LED, despite HID headlamp designs are just as blinding. Its not an LED issue, its a beampattern design issue.

Starlink beampattern at low elevation angles is likely even worse.

this is a Worldwide headlamp. Matrixbeam technology allow you top adopt any beampattern you need. SAE ECE LES ES or even CC regulation.

This paper shows that non-perpendicular axes in tri-axial velocity-sensors do not affect the overall shape of the resulting beampattern, but will introduce a pointing bias. doi.org/10.1121/2.0000969 #signalprocessing #acoustics #ASA175 @HongKongPolyU @csufcnsm

37/ This beampattern effect is also important in a “waveguide,” like when the signal is bound between parallel planes or oscillates about a minimum in wave speed. Here, the component of the beampattern parallel to the boundaries still affects the echo statistics.

35/ The beamwidth also affects the statistics. The narrower the beam’s mainlobe, the more structure present in the beampattern PDF due to more sidelobes. Also, a narrower mainlobe makes the echo statistics more “non-Rayleigh,” thus helping to classify scatterers.

34/ The beampattern PDF depends upon the spatial distribution of a scatterer. If the scatterer is uniformly distributed throughout the beam, the PDF is, to first order, power-law distributed.

33/ The beampattern function becomes a random variable because its value depends upon the random location of the scatterer. The distribution of the modulation of the echoes due to the randomized beampattern function is named the "beampattern PDF.”

32/ The echo varies with location of the scatterer in the sensor beam. Most sensor beams are highly directional and the value of the beampattern function modulates a scatterer’s echo. The modulation is randomized due to the random location of the scatterer.
