Description:
SLOTTED ROAD MARKER

BACKGROUND

Technical Field

The embodiments herein generally relate to a road marker which is self-illuminated using a light emitting diode LED and more particularly, to an embedded slotted road marker with a LED lighting which is installed within the roadway. The slotted roadway marker is well- suited for lane marking of walkways, highways, roadways, or airport runways, etc. The slotted road marker can be controlled by radio frequency controllers, motion sensors, photocells, etc.

Description of the Related Art Generally properly illuminating roadways, airport runways, or crosswalks at night is essential for maintaining a safe and accident free environment. Some locations such as roadways often require that illumination sources be highly visible even during the day, for example, highway stop line lights. However, it is difficult to find an illuminating means that is durable, relatively easy to install and remove, that is cost efficient, and easy to repair and maintain. Also such an illuminating means would have to provide excellent illumination without posing a threat as a physical obstacle to pedestrians and vehicular traffic.

The lanes of roads and highways are marked with thermoplastic paints, road studs to demarcate lane edges. Lane markings provide excellent guidance to the driver for safe driving. However, these markings are not very durable and they often fade off within few months of installation or application. Even the Reflective as well as solar road studs which are raised above the road surface get dislocated due to the impact of moving vehicles. Majority of the road are marked when they are newly constructed but within few months the markings vanish leading to unsafe road especially during night driving.

Currently there are various types of road marker used for lane marking having reflective surface, electricity powered road studs, illuminating stickers, paints, etc. All of these above markers are protruding or projected out of road surface. As a result the moving wheels of the vehicles have enormous impact on these road markers. Due to this impact, these road markers have very less durability and best of the industry products fail within a few months time due to moving traffic impact thus requiring frequent replacement or installation of new markers, thereby increasing the cost of maintenance of the roads, highways, etc.

Accordingly, there remains a need for a device or technique to provide roadway marking such that the device may be installed into or sunken or embedded within a tar road, a concrete, asphalt or any other flooring surfaces without any protrusion from the road surface. The device or technique should have much more durability, long life and avoid high impact from the tyres of the moving vehicles. The solution should also be cost effective, easy to install in present roadways, highways, pathways, etc. and be able to repair and maintain efficiently.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

As mentioned, there remains a need for a device or technique to provide roadway marking such that the device may be installed into or sunken or embedded within a tar road, a concrete, asphalt or any other flooring surfaces without any protrusion from the road surface. The device or technique should have much more durability, long life and avoid high impact from the tyres of the moving vehicles. The solution should also be cost effective, easy to install in present roadways, highways, pathways, etc. and be able to repair and maintain efficiently. The present embodiments herein provides a slotted road marker which is a self- illuminated light emitting diode LED is embedded within the road surface and is well- suited for lane marking of highways, walkways, roadways, or airport runways, etc. Referring now to the figures, more particularly to FIG. 1 and FIG. 5, where similar reference characters denote corresponding features consistently throughout the figures, preferred embodiments are shown.

FIG. 1 illustrates a typical arrangement of a road marker layout 100 on a road 102 according to an embodiment mentioned herein. In an embodiment, a road marker 104 may be used for lane marking. In one embodiment, each of the road markers 104 may be designed to have suitable number of light emitting diode LED's depending on the requirement of the road 102 or highways. In an embodiment, the markers 104 which emit light are installed at edges of the lane in existing joints or by making fresh groves in the road 102 surface. The pathway or road markers 104 may be totally embedded in the road surface without any protrusion above the road level. In an example embodiment, the road marker 104 may include a solar panel 106 of a suitable capacity along with designed printed circuit board PCB and a rechargeable Battery.

In one embodiment, the PCB with associated circuitry may be able to control operation of LED's. The solar panel 106 along with the PCB would be placed on a stand, concrete medians, kerbs, etc. or any other suitable locations on the edges or median of the road 102. In an embodiment, the solar panel 106 and PCB enclosure shall be 100 % water proof under appropriate IP ratings. In an embodiment, the solar panel enclosure may be connected to the road marker 104 through an interconnecting wire 108. In an embodiment, the interconnecting wires 108 may be installed through an existing road joints or by making fresh grooves within the road surface as shown in the layout of FIG. 1.

FIG. 2 illustrates an arrangement of a slotted road marker 104 which is placed inside the road 102 surface according to an embodiment mentioned herein. The road marker 104 may be specially designed to emit light and be prominently visible to an approaching vehicle from a long distance. The marker 104 even though may be embedded in the road surface and may be secured by a joint filler 110 without any protrusion above the road level, the light emitted from the road marker 104 may be visible from a long distance.

The single road marker 104 may be made with a single or multiple LED's 104A depending on the requirement of the highway or lane marking. In one embodiment, the road marker 104 may be designed to be waterproof with suitable ingress protection IP rating. In an embodiment, the single road marker 104 may be designed to sustain heavy load of all types of moving vehicles on the road 102. In an embodiment, the width of the road marker 104 may be designed to accommodate less space on the road surface.

FIG. 3 illustrates an exploded view of the slotted road marker 104 according to an embodiment mentioned herein. The slotted road marker 104 includes a housing which defines a container 104B with a dimension and configuration such that one side of the container may be exposed to surface of road. In an embodiment, other side of the container includes a detachable lid 104C. In one embodiment, the marker 104 further includes an at least one light emitting diode LED 104A which may be configured to be positioned at an angle and is disposed at one of the faces of the container 104B. In one embodiment, the slotted road marker 104 further includes a semi-tubular reflective surface element 104D and may be located below the LED 104A to reflect maximum light from one of the side of the container 104B and on to the surface of the road 102.

In another embodiment, the marker 104 further includes a printed circuit board PCB 114 having an associated circuitry and components to control the LED operation. In yet another embodiment, the slotted road marker 104 may include a solar panel 112 with a rechargeable battery 116 to power the PCB 114 and LED 104A. The marker 104 may be embedded within the surface of the road such as concrete roads, highways, tarmacs, runway, parking lot surface, etc. or like.

In one embodiment, we may classify the marker 104 in to three categories short distance visibility, medium distance visibility and long distance visibility. In short distance visibility, the pathway marker 104 may be used for smaller roads, shorter town/ city roads to have visibility up to 50 meters. The LED's 104A in this category of the marker 104 may be placed in such a position that light beam emitted 104E from these LED 104A is at an angle of 3 to 6 degrees to the road surface. Such an angle made by the light beam from the marker 104 makes the lane marking visible from a shorter distance by an approaching vehicle. In the medium distance visibility, the marker 104 may be used for comparatively medium range visibility from about 50 to 250 meters. The LED's 104A in this category of the marker 104 may be placed in such a position that the light beam 104E emitted from these LED 104A is at an angle of 2 to 3 degrees to the road surface. Such an angle made by the light beam from the marker 104 makes the lane marking visible from a medium distance by an approaching vehicle.

In the long distance visibility, the marker 104 may be used for long stretches of the road like highways, expressways, airports, etc., where the visibility would be from 250 meters to 1000 meters. The LED's 104A in this category of the marker 104 may be placed in such a position that the light beam emitted from these LED 104A is at an angle of less than 2 degrees to the road surface. Such an angle made by the light beam 104E from the marker 104 makes the lane marking visible from a long distance by an approaching vehicle.

FIG. 4 illustrates a standalone slotted road marker 104 according to one example embodiment mentioned herein. In one embodiment, the interconnecting wires 108 may be totally eliminated by enclosing the marker 104 and the solar panel 112 along with the PCB 114 in a single enclosure 118 or single standalone housing 118. The marker 104 with the LED 104A may be same as in the wired pathway marker 104 as mentioned above.

In an example embodiment, the enclosure 118 or container 104B may be elongated on the backside of the LED 104A to accommodate the solar panel 112, the PCB 114 and the rechargeable battery 116. In order to accommodate all the components in the elongated enclosure 118 or 104B, use of miniature units of the solar panel 112 and rechargeable battery 116 may be used.

FIG. 5 illustrates a two unit standalone slotted road marker 104 according to yet another example embodiment mentioned herein. In one embodiment, the two unit standalone slotted road marker 104 may include a Unit 1 and Unit 2. In an embodiment, the Unit 1 may include the LED 104A, the reflective surface element 104D and part of the printed circuit board PCB 114. In an embodiment, the part of the circuit board included in Unit 1 may be able to control the LED 104A operation. In an embodiment, Unit 2 may include the part of the PCB 114, solar panel 112 and the rechargeable battery 116.

In another example embodiment, the marker 104 with the LED 104A may be same as in the wired marker 104 as mentioned above. The LED 104A included in Unit 1 may have a small wire with a waterproof joint which may be connected to the solar panel 112 in the elongated enclosure Unit 2. In order to accommodate all the components in the elongated enclosure 104B use of miniature units of the solar panel 112 and rechargeable battery 116 may be used. In yet another embodiment, the solar panel 112 may be transparent or translucent and may be placed above the semi-tubular reflective surface element 104D. Such an arrangement may make the enclosure 104B, accommodating solar panel 112, rechargeable battery 116 and other associated circuitry more compact rather than elongated (ref Fig. 4).

In one example embodiment, the marker 104 may be used for walkways or footpaths, etc. The LED's 104A in this category of the marker 104 may be placed in such a position that the light beam 104E emitted from the LED 104 A is at an angle of more than 3 degrees up to 90 degrees to the road surface so as to be visible from very short distance by pedestrians.

In an advantages embodiment, the slotted road marker 104 may be used for wide ranging applications in various Industries such as a. Traffic safety - Lane marking on Roads, Highways and Expressways; b. Industrial Safety - As independent safety device for guiding the path or other purpose, during emergencies, especially during electric supply breakdown; c. Airport Marking - Lane marking; d. Commercial and Residential Complexes - As independent safety device for guiding the path during emergencies, especially during electric supply breakdown; and e. Parking lot markings - Public, Commercial and Residential areas.

In another advantageous embodiment, the placement and the design of the slotted road marker 104 may be made suitable for smooth movement of the vehicles avoiding a direct horizontal impact on the marker 104. This would significantly increase the durability and long life of the pathway markers. In yet another advantageous embodiment, the slotted road marker 104 would provide a long term and durable solution for lane marking during night time as well as day time driving (with extra bright LEDs 104A). This would provide an added safety feature for the roads and highways reducing the probability of accidents due to missing or invisible lane markings.

In an embodiment, the slotted road marker 104 may be made from materials such as polycarbonate, ABS, toughened glass, etc. In another embodiment, the slotted road marker 104 may be made from rigid or flexible material. Thus, various embodiments of the present disclosure offers the pathway marker 104 which may be a self- illuminated light emitting diode LED embedded within the pathway or roadway and is well-suited for lane marking of walkways, roadways, or airport runways.
