AUTOMATIC SIDE LAMP SYSTEM FOR VEHICLE TO REDUCE GLARE.

FIELD OF INVENSION:
This invention relates to the field of electronics, mechanical, electrical. The Invention described here is an AUTOMATIC SIDE LAMP SYSTEM FOR VEHICLE TO REDUCE GLARE comprising of a light source fitted on a plastic/metal housing, printed circuit board, dc power source, dc to dc converter, light sensors, controller, control circuitry, reflector, transparent cover and switches. The light source can be of any type like led, halogen, laser. This invention can be used to avoid accidents on road at night due to reduced visibility and glare caused by the headlight of oncoming vehicles by using a lamp on the side of a vehicle. The invention described here can be made in any shape and size.

BACKGROUND OF THE INVENSION: In low-income and middle-
income countries, the poor visibility of pedestrians and vehicles on the road is a serious problem. According to data gathered on traffic accidents, the maximum numbers of fatal road accidents occur during night says WHO. Older drivers have difficulty in judging where the edge of the road is especially when there is an oncoming vehicle with headlight and they need to move over on narrow country lane. European studies also have found that one third of pedestrian casualties had difficulty seeing the vehicle that had struck them, while two fifths of drivers had difficulty seeing the pedestrians. In terms of making driving easier at night the greatest preference from the drivers themselves was for better street lighting. It was recognized that this was impractical in non-built-up areas. There are also economic and environmental reasons why some organizations may wish to reduce the amount of lighting. There are also safety reasons why lighting needs to be available. However, there is the danger that an unconsidered removal or reduction in quality of light could actually increase accidents and their severity. Other options that might help would be better edge delineation of roads though delineation needs to be consistent throughout an entire country. Marker posts were also mentioned as another possible option. But these options need proper maintenance and that is not convenient. The main causes of collision of automobiles are the time taken by human reflexes to act on time. Reflex action is an involuntary and nearly instantaneous movement in response to a stimulus. When the driver drives a vehicle during night, increased headlight form the oncoming vehicle causes the eye pupil of the driver to constrict. This results in a reduced vision of the driver thereby reducing a reaction time of the driver. The visibility is dependent on the variations in the eye pupil size of the driver. Hence relying on the variations in the eye pupil size due to light stimulus is accurate and efficient method to avoid the reduced visibility problem. The loss of detail also increases anxiety and fear, further increasing adrenalin which in turn tries to widen the closed-down pupil to enhance peripheral vision in futility. This oscillatory (albeit negatively) reinforcing feedback loop results in high-stress and is
3

caused by lack of visibility of details in the shadows. This is akin to panic attack situation and could result in accidents. This demonstrates a need for a device to avoid loss of visibility from oncoming headlights or the like.

Object of invention:
1. The principle object of this invention is, to provide an AUTOMATIC SIDE LAMP SYSTEM FOR VEHICLE TO REDUCE GLARE, which is efficient, simple, cost effective and reliable solution for glare and poor visibility.
2. Another object of the invention is that any vehicle can use any headlight intensity on road.
3. Further object of the invention is to provide visibility to the driver and pedestrians on road.
4. Further object of this invention to provide a system, which is operative for a wide range of frequencies.
5. Further object is the safety of drivers and pedestrians.

PRIOR ART:
1) patent no.133037 on automatic device for reducing glare of headlamps of motor vehicles comprising at least one photo-electric element for being mounted on a motor vehicle so as to receive light from oncoming vehicular traffic and generate current. A transistor amplifier connected to the said photo-electric element for amplifying said current, said amplifier deriving power from a direct current source such as, the battery of said motor vehicle. A known shutter diaphragm for being mounted between the bulb-reflector assembly and the front cover glass of each headlamp of sad motor vehicle, the said diaphragm, when open permitting the full light of the said headlamp to pass through but when dosed, leaving only a small aperture so as to permit less light to pass through and thus reduce glare.
2) patent no.239962 on an automatic headlight controlling system for vehicle More particularly, it relates to a system which automatically controls the position (high or low beam) of headlights of a vehicle, differently/separately during day and night. The said invention is constructed especially to provide a system wherein at the same time the head light of the vehicle can be automatically put to two different positions i.e. the left side headlight at high/low beam position and right side headlight at low/high beam position.
3) patent no. 273707 on an ADJUSTABLE GLARE VISOR FOR NIGHT DRIVING includes an assy, of two linear polarizing filters, with their direction of polarization normally kept in the horizontal position, the first one fixed on to a rotatable tube in the bottom frame, and the second one, circular in shape, attached to a rotatable inner ring which can move through a guide provided in an outer frame attached to the right end of the rotatable tube. The bottom frame is connected to the base frame through two manually rotatable arms to adjust the position of the filter assembly to suit the convenience of the driver. The second polarizing filter and the inner ring is driven by a mini motor to adjust the intensity of the light to suit the drivers vision parameters. In
4

another embodiment a light sensor with a switching system is used to drive the second filter to automatically adjust the intensity of light.

DRAWBACKS OF PRIOR ARTS:
1. Inventions that are mentioned in prior art are very costly.
2. Even though the prior arts tend to reduce glare and increasing visibility, but they actually are not that efficient.
3. When they reduce glare they are also reducing driver’s visibility. This causes reduction in the speed of reflex action of the driver there by putting lives in danger.
4. Every vehicles headlight alignment need to be correct for prior art if not, dim light can also increase glare.
5. Due to the reduced efficiency of the prior art need of better edge delineation and street light is not reduced.

DETAILED DESCRIPTION OF THE INVENTION: Before the present invention is described, it is to be understood that this invention is not limited to particular methodologies described, as these may vary as per the person skilled in the art. It is also to be understood that the terminology used in the description is for the purpose of describing the particular embodiments only, and is not intended to limit the scope of the present invention. Throughout this specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. The use of the expression “at least” or “at least one” suggests the use of one or more elements or ingredients or quantities, as the use may be in the embodiment of the invention to achieve one or more of the desired objects or results. During day time when driving through the roads, drivers don’t have any problem in visibility of the roads even if high or low beam is incident on to eyes by the oncoming vehicle. So I conducted an experiment by using two motorcycles namely Motorcycle 1 motorcycle 2 driven by two different person’s driver 1 and driver 2 apparently the two motorcycles said above will have two light sources each namely head lamp 1 and side lamp 1 and head lamp 2 and side lamp 2. The light intensity of the two side lamp can be varied from zero to an intensity that is 15 times the intensity of the aforementioned headlamps. Light intensity of headlamp is same for the two motorcycles. These aforementioned motorcycles where placed 200 meter apart from each other and they were allowed to move closer to each other through a country lane road and the results were noted. The experiment was conducted for four different cases. Headlamps light beams are placed giving illumination to the front side of the road as normal headlamps of vehicles do. The side lamp is placed at the bottom right side of the vehicle, giving out light in an inclined position to the road surface on to the right side of the vehicle. The illuminating angle of the side lamp is chosen based on width of the road in which the automobile is travelling and the ground clearance and
5

dimension of the automobile it is fixed. The side lamp is only used to illuminate the road surface directly, the reflected light from the road will thus provide for the identification of pedestrians on the road side. The illumination of the road is for the area on the right side of the vehicle which is left when the area of a vehicle is avoided. A better understanding of the illuminance of the side lamp can be obtained by using a test screen. The test screen can be any white screen where we can mark points on it. It is kept 2 meter distant from the side lamp. The side lamp is fixed in a stand as if it is mounted exactly on a vehicle. When defining angles or distances the middle point of the light source of the side lamp shall be taken as center. In locating the test points, the following symbols shall apply: V: Is the line on a vertical test screen formed by the interaction of a vertical plane, perpendicular to the test screen, passing through the side lamp center. H: Is the line on a vertical test screen formed by the intersection of a horizontal plane, perpendicular to the test screen, passing through the side lamp center. H-V: Is the point of intersection of the lines H & V. The other points on the screen are designated by similar symbols to indicate the number of degrees of arc (alternatively the distance in millimeters) above or below H and the number of degrees of arc (alternatively the distance in millimeters) to the left or right of V when the screen is viewed from the position of the side lamp. For example, 1/2D- 5R is a point 1/20 below the horizontal and 50 to the right of the vertical. Similarly, 250U-1500L is a point 250 mm above the horizontal and 1500 mm left of the vertical. In this invention I used a side lamp which gives an illumination at points 60D-45L to 45R (Area which is below 600 to the Horizontal and in between 450right to 450 left of the vertical). Motorcycle 1 Visibility of driver 2 Motorcycle 2 Visibility of driver 1 Headlight 1 Side lamp 1 (intensity) Headlight 2 (intensity) Side lamp 2 (intensity) High beam = Headlight Poor High beam = Headlight Poor >5xHeadlight Good > 5xHeadlight Good >10x Headlight Best >10x Headlight Best These are the results of the experiment. On verifying the above table one can easily point out the fact that the visibility of the area is improved when side lamp intensity is greater than 10 times the intensity of headlight i.e. For proper vision the light intensity incident on the eyes should be less than or equal to the light intensity of the area that need visibility. Using this experiment, an equation can be deduced by inspecting the working of pupil of human eye. For clear vision, a definite amount of photons is required to reach retina, this is controlled by the pupil. Pupil constricts and dilates according to light Intensity of light incident onto the eyes, and permits only the number of photon needed
6

for the clear vision. Consider a surface on the background of a car that reflect a low light intensity, compared to high light intensity headlight of the same cars. When the headlight of this car is incident on to the eye of an oncoming vehicles driver on road. The pupil constricts and the amount of light or photon reaching the retina is thus adapted for the headlight. At this time, we can’t see the low light intensity surface because the photon count needed for the retina to sense them will not be sufficient as the pupil diameter is less because of the high intensity headlight. Now the eye can only sense objects or surfaces that reflect the same or greater light intensity than the headlight that is reaching the eye. That’s why we don’t have difficulties in day time when an oncoming vehicle on the road keeps its headlights switched on, because the light intensity of sun is very greater when compared to headlight intensity. By utilizing this phenomenon of our eyes, we can use a secondary light source with greater light intensity which can be used as a solution for the glare and poor visibility on the road. Now for the proper visibility of the surroundings this equation below should be satisfied.
Ieye = Isurr
Ieye is the intensity of light reaching our eyes.
Isurr is the light intensity reflected from the surroundings to our eyes. Throughout the specification any equation that represented in this description is not confined only as an equation or as an alphabetical or symbolic representation they also mean to satisfy the equation practically as well. Hereafter the word “condition” is used to implement the above equation. For our surroundings to accept this condition there is also another parameter to consider and that is the reflection of the material. The objects that fill our surroundings have different reflectivity as they are made of different materials. When driving through roads, reflection of the road surface and surroundings comes into consideration. So the said condition mainly depends up on the reflection of road surface (e.g. Asphalt) and the light intensity of the headlight of the vehicle it is fitted. The intensity of headlight is taken into account for calculating the maximum light intensity entering into the human eye. The above condition is thus calculated by the equation

??side = ??head ×[??head /(?? * ??head)]

Where
Iside=light intensity of side lamp
R= reflection of road surface I
head=light intensity of headlamp.

4. DC TO DC CONVERTER. 5. LIGHT SENSOR. 6. REFLECTOR. 7. TRANSPARENT COVER. 8. SWITCH. 11. DC SOURCE. The AUTOMATIC SIDE LAMP SYSTEM FOR VEHICLE TO REDUCE GLARE has a lamp comprising of singular or plurality light source (3) which can produce the aforementioned condition fixed on HOUSING (1) with reflector (6) having a transparent cover (7) on top. The lamp is fitted on the right side of an automobile (9) as in figure 2. This embodiment described here can be modeled into any shape and size. A LIGHT SENSOR (5) is used in the system to detect the presence of oncoming vehicle by detecting the light from it and is fixed on the front of the vehicle as in figure 2. The LIGHT SENSOR (5) converts photons to electrical signals. Thus when light is detected by LIGHT SENSOR (5) it sends electrical signals to the controller (2). A light source (3) is connected to a dc to dc converter (4). It is used here in the electronic circuit to reduce the current wastage by increasing the voltage by constant charging and discharging of an inductor. We can use controller (2) accompanied with control circuitry to maintain constant voltage at the output by giving pulse width modulated signals as input to the dc to dc converter (4). A dc source (11) which is a battery which provides current and voltage to the light source (3). The controller (2) is an integrated circuit like driver, microcontroller or timer that can be used to control the working of the entire system together with the control circuitry which comprising of electrical and electronic components. Controller (2) regulates the amount of voltage and current to the light source (3). The LIGHT SENSOR (5) sends signals to the controller (2) when light is detected form the oncoming vehicle on the road. Upon receiving the signal from the LIGHT SENSOR (5) the controller (2) activates the DC TO DC CONVERTER (4) there by activating the LIGHT SOURCE (3) by using the dc source (11). The HOUSING (1) of the light source (3) is covered by a transparent cover (7) or lens made out of fiber or plastic to protect the inside of the housing (1) against water, oxidation. Inside of the housing (1) there is a reflective type coating or reflector (6) used to focus and reflect light to specific area through the transparent cover (7).

Working: If there is no light incident on to the LIGHT SENSOR (5) then LIGHT SOURCE (3) won’t turn on. Whenever light falls on the LIGHT SENSOR (5) of the described embodiment, the CONTROLLER (2) is turned on with the help of a transistor which acts as a switch (8). Pulse width modulated signals with desired duty cycle are generated by the CONTROLLER (2) and are fed to the input of the DC TO DC CONVERTER (4) to
8

increase the voltage form the dc source (11) needed to turn on the LIGHT SOURCE (3) thus illuminating the road surface according to the condition.

ADVANTAGES: The advantages of using the AUTOMATIC SIDE LAMP SYSTEM FOR VEHICLE TO REDUCE GLARE, includes
1. Any vehicle can use head lamp with any light intensity on road.
2. Increases safety during night driving.
3. Increase the visibility of the road without sacrificing the visibility of the driver.
4. Use of street lights can be reduced.
5. Oncoming vehicles and vehicles on the right or left side of the vehicle will not face any difficulties in their vision. As the invention only provides light to the road. The intensity of reflected light from the road surface will be scattered all around the area to provide for the pedestrian’s vision.
6. In residential areas streetlight produces problems such as light pollution but on considering this invention the problem produced by light is reduced by 80% as the light is directed on to the road surface.
7. There are dark areas in roads between two streetlights can create weak vision spots. The invention described here can also be used to reduce this problem.
