Adaptive LED Headlight
Even when another vehicle is in front of you, the high beams will illuminate surrounding areas to improve visibility at night.
By
changing
the
high
beam
illumination
distribution
according
to
the
situation,
it
is
possible
to
use
low
beams
to
illuminate
oncoming
vehicles
and
vehicles
in
front
of
you
and
to
use
high
beams
to
illuminate
other
areas.
This
makes
it
easier
to
see
pedestrians
and
signs
on
the
sides
of
the
road,
and
also
improves
visibility
on
curves.
System operation
By
partially
turning
off
the
high
beams,
it
is
possible
to
brightly
illuminate
the
surrounding
area
even
when
there
is
a
vehicle
in
front
of
you.
The
portion
of
the
high
beams
that
are
turned
off
changes
according
to
the
direction
and
distance
of
the
vehicle
in
front
of
you,
and
the
high
beams
are
used
to
illuminate
the
widest
possible
area.
On
the
other
hand,
the
low
beams
always
illuminate
a
certain
range
to
ensure
visibility
in
front
of
you.
When there is a vehicle in front of you
The area surrounding the vehicle in front of you is illuminated with the high beams, and the high beams are only turned off for the area in front of you. The width of the area being turned off changes according to the distance between you and the vehicle in front of you.
When seen from your vehicle, the angle to the vehicle in front of you changes when you are on a curve, so the high beam's direction is changed by turning off a portion of the high beams.
When there is an oncoming vehicle
Similarly, when an oncoming vehicle is approaching, the direction and width of the portion of the high beams being turned off changes according to the position of the oncoming vehicle.
System mechanism
The
headlamps
consist
of
a
lamp
for
the
low
beams
and
a
variable
light
distribution
lamp
for
the
high
beams.
Multiple
LEDs
are
arranged
in
a
horizontal
row
inside
the
variable
light
distribution
lamp,
and
the
high
beam
illumination
distribution
can
be
changed
by
turning
each
LED
on
or
off
independently.
The
vehicle
in
front
of
you
is
recognized
by
the
multi-sensing
front
camera
installed
on
the
windshield.
Based
on
the
vehicle‘s
direction
and
distance
information,
the
control
unit
determines
the
area
where
the
high
beams
should
not
illuminate
and
then
controls
the
variable
light
distribution
lamp.
