Abstract:

Think of the days when road was laid in a basic

model. It is of a great gift to the people one who wishes to

travel. It finds its improvement as the days passes in all aspects

like 4 way track, speed track…etc. In this way of improvement

we also found improved features for safety for the drivers by

using reflector board, indication lights and signal. Among these

the road reflectors placed in the roads are very helpful for the

drivers especially at night because night driving is nearly a

blind driving due to the absence of bright source like lamp

posts at this time these reflectors play a role in making the

drivers to catch and follow the track. By these reflectors many

accidents are avoided and a state of improvement in these road

reflectors they are furnished now with led blinking lights which

run by solar power. In accordance to this as another step of

improvement this paper presents a new idea which will make

the reflectors self sufficient in its energy needs without costlier

equipments.

Keywords: Reflectors, led lights, battery, impellor, motor.

1. Introduction:

In today’s world there are many inventions and

improvements apart from these there are many process

involved in order providing safety. In such processes there are

many ideas and projects like getting electricity from speed

breakers (or) bumps. The idea is really good but the purpose of

the speed breaker is lost. Once a driver crosses and feels that it

is not disturbing him (I.e.) it goes in and merges to the same

surface of the road. And so the next time he passes he won’t

slow his vehicle. So this paper focuses on making reflectors self

sufficient but at the same time it is made sure that it maintains

its purpose.

2. Disadvantages in the previous advancements:

Reflectors uses battery to power the led’s no one

wishes to change the battery when it goes off.

Reflectors use power from main lines. Wastage of

money in wiring the reflectors.

Reflectors are placed with a solar panel at top which

absorbs the sunlight and so it produces electricity. Due

to speed of the vehicles and the crossing of over

weighed vehicles it breaks off.

Reflectors with piezo crystals when the vehicle moves

it crushes and so current is produced and used. It is too

costly.

And so many innovations are at the speed breaker

level like

Crank-shaft mechanism

Roller mechanism

Rack- Pinion mechanism

But these ideas really fail due to the only reason that the

purpose of the speed breaker is lost.

3. Principle:

The principle behind the working process is when

an automobile passes the reflector it just presses it due to the

force it presses the air in the chamber get compresses and it is

made to gush out through a small nozzle. The high pressure

air coming out of the nozzle will hit the impellor placed

under it. And so the impellor rotates and the generator which

coupled to the same shaft rotates so some amount of

electricity is produced. This process continues to happen

during the day time since numerous vehicles passes over and

thus electricity required to light the led’s are obtained hence

the current stored during daytime is utilized for the led’s

blinking at night.

5. Construction:

IDEA 1:

In this reflector is placed in a chamber having a

hole at the bottom it is also placed in the lifted position by

means of a spring. The bottom portion has a battery, motor and

an impellor attached to it. The impellor is connected to the

motor and in turn the electricity generated is taken through

wires to the battery for storing purpose

IDEA 2:

In this the same above is done in addition to that the

chamber here encloses the propellor and shaft also so that the

air which is compressed down is again reused and taken up

again into the upper chamber by means of a telescopic capillary

tube.

5. Working:

IDEA 1:

STEP 1: When an automobile passes over the reflector

the reflector gets pressed and so the air present

inside the chamber gets compressed and bears a high pressure

STEP 2: Now the pressurized air gushes out of the nozzle.

STEP 3: The gushed out air forces the impellor to rotate.

STEP 4: Impellor is coupled to generator and so it rotates

in turn producing electricity

STEP 5: Electricity produced is stored in the battery for

further usage.

IDEA 2:

Same process as in idea 1 after this.

STEP 6: The air which comes compressed from the

upper layer after completing its work it again goes back to the

upper layer through the capillary tube due to the vacuum

created in the upper layer by the raising of the reflector by the

spring force as the vehicle moves.

Advantages:

IDEA 1

Simpler process

simple in construction

Accidents can be avoided

Cost is comparatively cheaper to solar panel

based reflector

Purpose is not lost as such in speed breaker

model

IDEA 2

Not affected by stagnant water

8. Disadvantages:

IDEA 1

Hard to place it

Spoiled by stagnant water

IDEA 2

expensive than idea 1

9. Conclusion:

From this paper we heard new techniques making

reflectors self sufficient for its energy needs which will

reduce the accidents or making the drivers alert about the

track when they are driving at nights. I hope that these

ideas will be taken into consideration and implemented so

that it will be helpful to the drivers driving at nights

indicating the crossings, tracks, and road closings….etc.
