THE ROAD ACCIDENTS IN INDIA
India tops the world in road accidents- About 4
lakh accidents per year About 80,000 people die
every year About 4 lakh persons are injured every
year Millions of minor mishaps go
unreported Economic cost is about Rs. 6,000
crores per year
3
NATURE OF ACCIDENTS 60 of accidents occur
during the night. Major accidents are head on
collisions. Heavy vehicles are involved in major
accidents. High ways account for a major share of
accidents. CAUSES OF ACCIDENTS Human failure is
the major cause for accidents. Glare from head
lamps is a serious problem on Indian roads.

DAY Vs NIGHT DRIVING Human Eye is a wonderful
gift of nature. Nature has given us all visual
capabilities for a natural life. Human beings
were ordained/destined to be active during
day. The bright and uniform solar radiation helps
us in the day. Modern man has created a new need
for faster night travel. Artificial lamps
invented to aid the vision during
night. Artificial lamps also create disability
glare. Naturally evolved eye can not cope with
this glare. NIGHT DRIVING THROWS A CHALLENGE
5
WHY NIGHT DRIVING IS A CHALLENGING TASK? What
we sense visually depends on 1.Physical size of
the object. 2.The illumination towards the
object. 3.The reflectance factor of the
object. 4.Colour and luminance contrast of the
object. 5.Time constancy and its moment in
space. 6. Physiological and psychological
state. 7. Perception method of the
viewer. PLUS Wattage of our head lamps. The
direction and spread of our beam, The alignment
of our lamps. THE DISABILITY GLARE FROM AN
OPPOSING MAIN BEAM WILL HAVE THE FINAL SAY
6
HOW TO AVOID GLARE? The internationally accepted
solution to avoid glare is to dip. All the
automobiles come with a Dipper switch. All the
automobiles are equipped with Main and Dip
beams. THE KEY CONFLICT MAIN BEAMS Designed to
illuminate a large field. DIP BEAMS Designed
to reduce glare to the opposite
driver. VISIBILITY and GLARE are the crucial
issues. One needs to balance the needs of all
road users. One needs to pay attention to safety
above the speed. Dipping avoids GLARE.
7
Why the poor dipping practices in India?
Practical difficulties like sheer number of
operations. Physically exhausted to operate a
dipper switch in the late night. Psychologically
frustrated to think coolly and rationally. All
the attention focused on steering control at the
cost of safety. Sometimes Subjective factors
like False ego, skepticism, arrogance, Lack of
concern, narrow vision, etc can also come in the
way. Solution to all the above issuesRAKSHA

PHILOSOPHY OF RAKSHA

• The roads are meant for all users on an equal
  footing.
• We have a right to travel like many others.
• The road safety is inter dependant and
  interlinked.
• If the opposite vehicle is driven safely we are
  safe.
• Our vehicles glare can make others to commit
  mistake.
• We can be the pilots in dipping for others to
  follow.
• By dipping our head lamps first we are leading a
  path.

10
THE KEY FUNCTIONS It maintains head lamps in dip
beam on lit roads. It maintains high beam on a
dark road free of opposing Traffic It dips the
lamps on sensing a four wheeler at 230 meters. It
continues in the dip beam till cross if the OV
dips. It restores main beam at 130 meters. If OV
does not dip. It responds even to a two
wheeler/weak dip beam etc.

INSTALLATION OF RAKSHA.

• RAKSHA can be installed in any automobile.
• The entire process has only two steps.
• Physical installation
• Electrical integration

13
Physical Installation of Raksha
Raksha is provided with the needed flexibility to
convenient installation and alignment with the
axes of the automobile. The ball joint and
pedastal as shown below can be used for the
purpose.
Loosen the four screws to release the ball joint
Remove the pedastal screw To disengage the
interlock
14
After Loosening the four screws the ball joint
releases for aligning levelling RAKSHA.
After Removing the screw pedastal can be rotated
for alignment of RAKSHA.

Where to install RAKSHA
17
Physical Installation of Raksha
Raksha is to be installed at about 5 feet 1
foot from the ground. In the case of trucks and
buses the position could be at the lower end of
the wind shield. For cars and jeeps this could be
at the upper end of the wind shield.
18
For trucks and buses Raksha is placed as follows.
Linked to Wind sheild
Fixed to the dash board top
19
Pedastal to the roof/frame.
Fixed to Wind sheild
20
Physical Installation of Raksha
After firmly fixing raksha at the selected
location, it should be aligned to the axes of the
automobile as shown below.

IMMUNITY OF RAKSHA
RAKSHA is designed to be immune to unwanted
signals so that it can meet the needs of the
actual field conditions.
29
How Raksha Speaks
For convenience raksha indicates 1.Road lighting
status Lit road or Dark
Road 2.Out put beam status and -- Main
beam or Dip beam 3. The mode status
-- AUTO or Manual
If the Solid state relay trips due to fault all
LEDs will flash
30
ACTIVATION OF RAKSHA Raksha will be active the
moment the head lamps are switched ON and will
be deactivated with switching OFF. RAKSHA IS
ACTIVATED AND DEACTIVATED WHEN MODES OF RAKSHA
LIT ROAD MODE Raksha enters into this mode on
sensing that the road is well lit. DARK ROAD
MODE Raksha enters into this mode if the road
is not well lit.
31
Operational control of raksha
Raksha integrates with the existing dipper switch
and gets activated or deactivated as per the
position of the switch.

Maintenance of Raksha Raksha does not need any
maintenance. How ever ensure that 1. The lens
window is always clean. 2. The lens window is
exposed to the opposing light. 3. The lens should
not be touched with oily or greasy
hands. Improper leveling will lead to improper
functioning. Hence dont disturb the level For
best results Use only efficient bulbs of
sufficient wattage, aligned properly.

USERS OF ALL VEHICLES ! DIP YOUR LAMPS !! YOU
HAVE NOTHING TO LOOSE EXCEPT AN ACCIDENT !!!
