Abstract
An improved highway barricade light, with increased visibility and operational life span that can be installed on a common traffic channelizer, without preventing the stacking of the channelizer. A base with hand-hold features is attached to the top of a traffic channelizer. The base holds a rechargeable power supply, control circuitry, switch, solar cell and a photoresistor. A reflector ring attaches to the base and holds an array of light emitting diodes (LED) circumferentially around the device. The LED's can be controlled to create a variety of flashing patterns to direct motorists, including, but not limited to, constant burn, flashing, clockwise, counter-clockwise, upward, downward and random. A transparent or translucent cover attaches to the base to protect the components, and may be flat, conical or dome shaped.
Description
- The present application is a continuation-in-part application of U.S. provisional patent application, Ser. No. 60/661,561, filed Mar. 14, 2005, for DIRECTIONAL HIGHWAY BUOY, by Steven J. Frey, included by reference herein and for which benefit of the priority date is hereby claimed.
- The present invention relates to construction barricade lights and, more particularly, to light emitting devices that provide motorists with information regarding speed, direction and avoidance of hazards.
- Traffic channelizing devices (channelizers) are used at the present time to warn and alert drivers of roadway hazards created by work activity in or near the traveled way and to direct traffic along a desired route and safely past these hazards. A series of traffic channelizers may be positioned one after another along the roadway to channel traffic in a construction zone from one or more lanes into fewer lanes. Metal drums have been replaced by plastic traffic channelizers like those disclosed in U.S. Pat. No. 3,952,690 for many reasons, including the plastic channelizer's ability to be stacked, thus reducing storage space. Additionally, channelizer mounted light units, commonly called barricade lights, are required to be used in virtually every road construction project in order to warn and alert motorists generally to the presence of the construction zone. These lights are configured to operate in either a steady burn mode or in a flashing mode. Current barricade lights, although familiar to most drivers, are not without their flaws.
- Most barricade lights in use today are similar to those disclosed in U.S. Pat. No. 3,818,439, consisting of an incandescent light bulb, inside a unidirectional lens housing, and powered by two six-volt zinc-carbon lantern batteries. Since these batteries must be replaced after every 250 hours of service (for steady burn lights) or 1000 hours of service (for flashing lights), considerable expenses are incurred for both the purchase of new batteries, and the maintenance labor costs, not to mention the physical danger to maintenance workers in active construction zones.
- The safety barricade industry is currently the single largest user of zinc-carbon lantern batteries, and uses millions of those batteries each year. According to the United States Battery Act, 1996, the United States Environmental Protection Agency (EPA) recommends disposal of zinc-carbon batteries in common municipal waste incinerators or landfills. When incinerated, hazardous heavy metals vaporize into the air and pollute lakes and streams. These same heavy metals can also leach from solid waste landfills. In either case, poisonous compounds make their way into the food chain, causing serious health risks to humans and animals. Mild symptoms of poisoning by these compounds can be coughing, headaches, and vomiting. Children are the most highly affected by the metals, with effects such as damage to their central nervous system, seizures, and perhaps even mental retardation.
- In addition to the health risks to the population, the use of common barricade lights are not enough to safeguard motorists. On Feb. 10, 2004, the Savannah Morning News reported, “The Georgia State Patrol said a 1996 Chevrolet Cavalier driven by John Walls, 18, hit a construction barrel about 8:30 PM and swerved toward an embankment at Exit 67. The vehicle rolled over several times and stopped at the bottom of the ramp.” Mr. Walls' brother, Harley, 20, of Middleburg, Fla. was pronounced dead on the scene. Although barricade lights are required by law at nearly every road construction work zone, more than 40,000 people are injured each year as a result of motor vehicle crashes in work zones, according to the U.S. Department of Transportation Federal Highway Administration. The number of persons killed in the U.S. in motor vehicle crashes in work zones has risen from 872 in 1999 to 1,028 in 2003 (an average of 1,020 fatalities a year). Traffic experts believe much of the increase can be attributed to the proliferation of road renovation and expansion projects as states take advantage of an increase in federal funds available for road work, and will continue to increase.
- Another shortcoming of typical barricade lights like those disclosed in U.S. Pat. No. 3,818,439, is that the light emitted by these devices is normally seen in only one direction. Traffic control lamps and warning lamps need to emit light in an omni-direction in order to properly signal those approaching the lamps from all directions and conditions. Additionally, physiological studies show that flashing lights draw attention more than steady state lights, however a number of flashing warning lights when used in conjunction with channelizers, flash randomly or indiscriminately presenting a confusing fire-fly type scene to the approaching driver and do not provide any direction or delineation, and may actually create additional distractions and danger to motorists.
- Barricade lights currently being employed on an industry wide basis, are designed around the use of an incandescent bulb as the light source. The average life of an incandescent bulb used under ideal conditions is only 400 hours and the bulbs tend to burn out at different and very unpredictable rates. Everyday environmental conditions such as variations in temperature, voltage, shock and vibrations shorten the bulb's life span.
- The combination of consumable batteries and light bulbs limit the life span of each barricade light to but a few months. Additionally the very use of these lights negate the benefits of using plastic channelizers, by preventing the stacking of the channelizer with the light attached, and as a result, many channelizers are put into service on the road without the installation of a barricade light, even though they are required by law in most situations.
- In addition to the aforementioned barricade light as disclosed in U.S. Pat. No. 3,818,439, other barricade lights have been developed. To attempt to address the concerns of battery usage, U.S. Pat. No. D254,658 discloses a device which makes use of solar cells to recharge internal batteries. The configuration shown, which is similar to other solar powered devices, may be prone to accumulation of dirt and moisture when exposed to the elements resulting in decreased solar efficiency due to the flat horizontal upper surface of the solar cell array, which is exposed to the environment, thus significantly reducing its effectiveness. To address this specific issue, devices such as the one disclosed in U.S. Pat. No. 4,772,990 place the solar cells inside the body of the device, but due to the limitation of the overall package space of such an arrangement, the size of the solar cells must be kept at a minimum, thus drastically reducing their potential electrical output and effectiveness.
- To increase the life span and reliability of their illumination function, some barricade lights, like the one disclosed in U.S. Pat. No. 4,841,278, eliminate the use of incandescent light bulbs in favor of longer lasting, more efficient light-emitting diodes (LED)'s. Although more cost effective and environmentally friendly than common barricade lights, solar-powered devices using LED's, like the one disclosed in U.S. Pat. No. 4,841,278 only address longevity, and do not increase, nor provide nearly enough, visibility or information to properly guide motorists through construction work zones.
- In an attempt to better control the flashing of multiple barricade lights, devices like one disclosed in U.S. Pat. No. 4,132,983 synchronize an array of barricade lights to flash simultaneously. From a driver's perspective, the visual stimulus of an entire lane of barricade lights turning on and off at the same time could potentially cause a hypnotic or distracting effect, and actually do more harm than good. To mitigate this risk, controllers such as the one disclosed in U.S. Pat. No. 3,938,080 cause barricade lights to flash in a predetermined sequence. Although an improvement, this system only provides motorists with improved depth perception, and does nothing to provide direction or speed information. Additionally, if the arrangement of channelizers along the roadside is not in a precise enough manner, or worse re-arranged out of sequence, such flashing lights could provide the very fire-fly type scene the device is attempting to avoid.
- At the present time, we have no knowledge of a traffic control element and, in particular, a barricade light with a perpetual life span, safe for the environment, highly visible without being distracting to drivers, providing directional information, and with the ability to be permanently attached to a channelizer without preventing the channelizer from being stacked.
- It is therefore an object of the invention to provide a highway barricade light.
- It is another object of the invention to provide a highway barricade light with a plurality of flashing lights, circumferentially located around the device. The flashing lights can be configured and controlled to flash in a number of predetermined sequences. Depending on the sequence and flash rate, an approaching motorist would perceive movement, in a particular direction.
- It is another object of the invention to provide a highway barricade light with a power supply that can be recharged with solar energy.
- It is another object of the invention to provide a highway barricade light with a photoresistor to turn the light on at dusk, and off at dawn, if desired.
- It is another object of the invention to provide a highway barricade light with a transparent or translucent cover or dome to protect the internal components.
- It is another object of the invention to provide a highway barricade light that may be attached to the top of a traffic channelizer in such a manner that the channelizer may be stacked with the device attached.
- It is another object of the invention to provide a highway barricade light with hand-hold features so that the device can be lifted by itself or when attached to a traffic channelizer.
- In accordance with the present invention, there is provided an improved highway barricade light, with increased visibility and operational life span that can be installed on a common traffic channelizer, without preventing the stacking of the channelizer. A base with hand-hold features is attached to the top of a traffic channelizer. The base holds a rechargeable power supply, control circuitry, switch, solar cell and a photoresistor. A reflector ring attaches to the base and holds an array of light emitting diodes (LED) circumferentially around the device. The LED's can be controlled to create a variety of flashing patterns to direct motorists, including, but not limited to, constant burn, flashing, clockwise, counter-clockwise, upward, downward and random. A transparent or translucent cover attaches to the base to protect the components, and may be flat, conical or dome shaped.

FIG. 1 is a perspective view of adirectional highway buoy 10 as installed on acommon traffic channelizer 12. -
FIG. 2 is an exploded view of adirectional highway buoy 10 showing its internal arrangements and illustrating optional mounting method to acommon traffic channelizer 12. Thebase 14 is generally circular or disk shaped, being of similar size and shape as the top of atraffic channelizer 12. The base 14 may be made from a single component, or may be made of several individual parts suitably fastened, welded or glued together. The base 14 may be made from plastic, metal, or any suitable material. Afastener 16 is passed through ahole 46 in thebase 14 and amount hole 48 in thetraffic channelizer 12, and is secured with anut 18, to retain the base 14 to thetraffic channelizer 12. Thebase 14 provides support and retains thecontroller 20,battery 26,reflector ring 28,solar cell 34 andcover 36. - The
selector switch 24 andphotoresistor 22 may be attached directly to thecontroller 20 as shown inFIG. 2 , but may also be mounted directly on thebase 14, or any other suitable location to allow proper operation of theselector switch 24 andphotoresistor 22. Thereflector ring 28 may be made from a single component or several individual parts as shown inFIG. 2 . Thereflector ring 28 retains a plurality ofLED retainer 30 circumferentially around the device. TheLED retainer 30 retains a plurality oflight emitting diode 32, the pattern of which made be, but not limited to a vertical arrangement. Thereflector ring 28 is shaped to provide a plurality ofreflector 44 to reflect and focus light in an outward direction. Thereflector ring 28 may be made of plastic or metal and may be, but not necessarily, finished in a mirrored or reflective surface. - The
cylindrical cover 36 is to be made from a translucent or transparent material and can be, but not limited to, a flat, conical or domed shaped top. Thecover 36 is retained to the base 14 with a plurality ofscrew 38 which may be, but not necessarily, tamper-resistant. -
FIG. 3 is a front section view of adirectional highway buoy 10 having front and rear views the same. Thebase 14 is shaped to provide one or more optional hand-hold 40. Aswitch access hole 42 is also provided in the base 14 to allow access for asecondary tool 54 such as, but not limited to, a screwdriver for the manipulation of theselector switch 24. -
FIG. 4 is a side partial section view of a pair oftraffic channelizer 12, each with adirectional highway buoy 10 installed, being stacked one on top of another. -
FIG. 5 is a schematic view of adirectional highway buoy 10 electrical diagram. During daylight hours, sunlight passes through thecover 36 and strikes thephotoresistor 22 and thesolar cell 34, which are wired to thecontroller 20. Thephotoresistor 22 senses the amount of ambient light, and sends an electrical signal to thecontroller 20, to indicate whether it is day or night. - During daylight hours, the
solar cell 34 produces electricity which is passed to thecontroller 20. Thecontroller 20 supplies electricity to thebattery 26 to charge thebattery 26, and deactivates the plurality oflight emitting diode 32. - At night, the
solar cell 34 stops producing electricity, and thecontroller 20 draws electricity from thebattery 26 to provide electrical power to a plurality oflight emitting diode 32. - Depending on the position of the
Selector switch 24, thecontroller 20 turns the plurality oflight emitting diode 32 on or off, depending on the desired effect. The device can be set to turn off alllight emitting diode 32, in the case of storage or transport of the device. The device can be set to turn on alllight emitting diode 32, in the case of a constant burn application. The circumferential and vertical array of the plurality oflight emitting diode 32 also allows thecontroller 20 to create a variety of flash patterns. The patterns include, but not necessarily limited to the following; sequential clockwise, sequential counter-clockwise, vertical upward direction, vertical downward direction, or random. -
FIG. 6 is a perspective view of a road construction work zone. A plurality oftraffic channelizer 12 withdirectional highway buoy 10 are placed on theroadway 50. When thedirectional highway buoy 10 is set to flash thelight emitting diode 32 in a counter-clockwise direction as shown, the visual effect, as seen from the approachingmotor vehicle 52 is a sequentially flashing light from left to right. The driver of themotor vehicle 52 is visually directed to the right, regardless of the alignment of thetraffic channelizer 12 on theroadway 50. Because the plurality oflight emitting diode 32 are arranged circumferentially around the device, the same visual stimulus is received by allmotor vehicle 52, regardless of their direction of travel. -

When thedirectional highway buoy 10 is set to flash thelight emitting diode 32 in a clockwise direction as shown, the visual effect, as seen from the approachingmotor vehicle 52 is a sequentially flashing light from right to left. The driver of themotor vehicle 52 is visually directed to the left, regardless of the alignment of thetraffic channelizer 12 on theroadway 50. Because the plurality oflight emitting diode 32 are arranged circumferentially around the device, the channelizer does not need to be placed on theroadway 50 in any particular orientation, as the same visual stimulus is received by allmotor vehicle 52, regardless of the orientation or alignment of thetraffic channelizer 12. -
FIG. 8 is a perspective view of a road construction work zone. A plurality oftraffic channelizer 12 withdirectional highway buoy 10 are placed on theroadway 50. When thedirectional highway buoy 10 is set to flash thelight emitting diode 32 in a top to bottom, or downward, direction as shown, the visual effect, as seen from the approachingmotor vehicle 52 is a sequentially flashing light from top to bottom. The driver of themotor vehicle 52 is visually directed down, which would indicate a need to reduce speed. Because the plurality oflight emitting diode 32 are arranged circumferentially around the device, the same visual stimulus is received by allmotor vehicle 52, regardless of their direction of travel, or the orientation or alignment of thetraffic channelizer 12. -
FIGS. 6-8 illustrate only a few of the combinations oftraffic channelizer 12 layouts anddirectional highway buoy 10 flash patterns possible, and are in no way intended to illustrate the only layouts and patterns possible. By combiningseveral traffic channelizer 12 anddirectional highway buoy 10 flash patterns, traffic can be easily and safely directed to avoid hazards, merge and shift travel lanes, and reduce speed. - Since other modifications and changes varied to fit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the example chosen for purposes of disclosure, and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
