New high beam lamp does not dazzle other drivers

Stanley Electric Co Ltd has developed a high beam lamp that does not dazzle the drivers of vehicles running ahead or coming in the opposite direction.

The lamp, "Adaptive Driving Beam (ADB)," was demonstrated in the company's booth at Ceatec Japan 2014 last week in Chiba Prefecture.

It takes images of scenes ahead of the vehicle with a camera attached to, for example, the back of the rear-view mirror, detects the direction of a vehicle running ahead or coming in the opposite direction and turns off part of the high beam emitted in the direction. As a result, it becomes possible to avoid dazzling other drivers while emitting light to a distance and ensuring a clear view at night.

The light source of the ADB uses 12 LED chips, which consist of four blocks. By turning on/off each block, it becomes possible to block part of the light directed at other vehicles. With right and left high beam lamps, there are eight emission patterns.

The lamps are slowly turned on/off so that the driver of the vehicle does not feel odd. And the speed of turning on/off the lamps slightly changes in accordance with the speed of the vehicle.

"Although the hardware was developed by combining existing technologies, it was difficult to adjust the control technology such as the function to slowly turn on and off the lamps," Stanley Electric said.

Some other manufacturers have already commercialized ADBs that block part of a high beam depending on the existence of a vehicle running ahead or coming in the opposite direction. But the ADB developed by Stanley Electric is controlled only by switching on/off LED chips and does not use a mechanical structure. The company will consider applying the ADB in consultation with finished car manufacturers, etc.

As I get older, the high beams of other driver are becoming a serious problem for me. They were always a hazard which is why most traffic laws require them to be dimmed when there is an oncoming car, but I now see that age and high beams are a very dangerous combination.

This seems like a great idea!

Very nice, now if someone could explain to Japanese drivers what fog lamps are for, and why they should not be used on a beautiful cloud free summers night...... then these new super duper high beam lights may make sense...

Fog lamps. Aftermarket H.I.D. bulbs fitted sans projector. Bluish lamps.

All of these dazzle oncoming drivers. Full beams are seldom a seldom an issue - especially when lots of Japanese have already festooned their cars with more lights than a Christmas tree.

Or here's an idea... DON'T turn on your high-beams when another car, bike, or pedestrian is approaching. You're supposed to do the opposite; high beams to see better and further in low-lit areas, low-beams for well-lit areas and/or areas with a lot of traffic. I love the way most Japanese drivers shut off their lights at an intersection out of courtesy, but the number of times I've nearly crashed on my bike because I'm blinded when someone flicks on their high beams when oncoming is very, very high.

Japanese drivers shutting off their lights at an intersection started off as a measure to "save energy", during the oil crises in the early 1970's.

I can't count the number of times I have seen Japanese drivers forget to turn their headlights back on after the light changes. Dangerous!

Just pedestrians and cyclists.

Hey ArtistAtLarge, get your eyes examined for cataract.

Mai Yenish, I thought it was about courtesy. Saves energy? How much?

Pretty cool idea.

I think it is a great concept, if it works. I don't understand the writers choice of the word dazzle. I undersatand that it is correct, but it is not commonly used to mean blind these days. I cannot think of ever seeing this word in this context. I think, blind on coming drivers would have been a better choice for lucidity. But hey, it made me read the article.
