FIELD OF THE INVENTION

The present invention relates to the field of accident prevention systems, more specifically, a driveway edge illumination system.

BACKGROUND OF THE INVENTION

It may be unsettling to back out of a driveway that a person is not familiar with after dusk when the ambient lighting is poor. A driver may not be familiar with the width and course of a driveway. The available lighting, even with backup lights of a vehicle on, may be insufficient to clearly define the boundary between the driveway and a lawn. The driver may not be familiar with the positioning of objects that are just off of the driveway. As non-limiting examples, the driver may not realize that there is a risk of driving into a drainage ditch or striking a mail box, a telephone pole, fencing, a tree, a retaining wall, or other objects if the vehicle leaves the driveway by even a few inches. In addition, the lawn may be soft due to weather conditions and the vehicle may damage the lawn if it leaves the surface of the driveway. The situation may be exacerbated if the driveway is curved.

The driveway edge illumination system 100 (hereinafter invention) may comprise one or more edge lights 200, one or more sensors 240, and at least one controller 230. The one or more edge lights 200 may be positioned along one or more edges 902 of a driveway 900 and may be illuminated to mark the one or more edges 902 of the driveway 900 at night. The at least one controller 230 may illuminate the one or more edge lights 200 based upon one or more sensor signals received from the one or more sensors 240. The one or more sensors 240 may inform the at least one controller 230 of activity within one or more monitored zones 290 via the one or more sensor signals. As non-limiting examples, the activity may be the presence or movement of a person or a vehicle within the one or more monitored zones 290. The at least one controller 230 may be operable to extinguish the one or more edge lights 200. The at least one controller 230 may illuminate and extinguish the one or more edge lights 200 by applying and removing an electrical potential to the one or more edge lights 200.

An individual edge light 202 selected from the one or more edge lights 200 may be placed along an edge 904 of the driveway 900 such that the individual edge light 202 is visible from within a vehicle when the individual edge light 202 is illuminated. As non-limiting examples, the individual edge light 202 may be adapted to be visible to a driver directly, via a rear view mirror, via a driver side mirror, via a passenger side mirror, or combinations thereof. The individual edge light 202 may be positioned such that the individual edge light 202 is adjacent to the driving surface of the driveway 900. The individual edge light 202 may be positioned such that the individual edge light 202 is not damaged if the vehicle leaves the driveway 900 and runs over the individual edge light 202. As a non-limiting example, the individual edge light 202 may be below grade level such that the top of the individual edge light 202 may be flush with the top surface of the driveway 900.

The individual edge light 202 may be an elongated, flexible, light tube. As non-limiting examples, the individual edge light 202 may be a rope light or a soft neon light. The individual edge light 202 may have any cross-sectional shape. In preferred embodiments, the individual edge light 202 may have a circular or rectangular cross-section.

The individual edge light 202 may comprise a plurality of lamps 210, a jacket 212, a core 222, one or more lamp interconnections 214, and a first power connection 216. The jacket 212 may be a covering that protects the one or more edge lights 200 from physical and environmental damage. The jacket 212 may be non-opaque such that light emitted by the plurality of lamps 210 is visible from outside of the jacket 212 when the plurality of lamps 210 are illuminated. Each end of the jacket 212 may be covered by an end cap 220 to seal the jacket 212 and to prevent water from entering the jacket 212. The individual edge light 202 may be waterproof such that ground moisture or water flowing over the individual edge light 202 does not disrupt the operation of the individual edge light 202.

The plurality of lamps 210 may be sources of illumination disposed along the core 222 within the jacket 212. The plurality of lamps 210 may be LEDs to optimize power consumption and life of the plurality of lamps 210. The plurality of lamps 210 may be electrically coupled to each other and to the first power connection 216 via the one or more lamp interconnections 214 such that the electrical potential applied at one end of the individual edge light 202 via the first power connection 216 may cause all of the plurality of lamps 210 to illuminate. The plurality of lamps 210 may be any color. In a preferred embodiment, the plurality of lamps 210 may glow red when illuminated such that the individual edge light 202 is adapted to preserve night vision.

In some embodiments, the individual edge light 202 may comprise a second power connection 218 at the end of the individual edge light 202 that is opposite the first power connection 216. The second power connection 218 may be electrically coupled to the one or more lamp interconnections 214. The length of the one or more edge lights 200 may be extended by coupling the second power connection 218 of a first edge light 204 to the first power connection 216 of a second edge light 206.

The one or more sensors 240 may be adapted to send the one or more sensor signals to the at least one controller 230 whenever the one or more sensors 240 detect motion, light, proximity of a person or vehicle, or combinations thereof which may be indicative of the activity in the one or more monitored zones 290 of the one or more sensors 240. As non-limiting examples, the one or more sensors 240 may use passive IR technology, reflected electromagnetic energy, reflected ultrasound, or combinations of the above to detect the activity.

The at least one controller 230 may determine when the one or more edge lights 200 are to be illuminated and when the one or more edge lights 200 are to be extinguished. The at least one controller 230 may comprise a timer 234. A determination to illuminate or to extinguish the one or more edge lights 200 may be based upon input received from the one or more sensors 240, a time interval determined by the timer 234, or combinations thereof. In a preferred embodiment, the at least one controller 230 may illuminate the one or more edge lights 200 when the one or more sensors 240 indicate that the activity may be within the one or more monitored zones 290 and may extinguish the one or more edge lights 200 after the time interval has elapsed. As a non-limiting example, a person walking to their vehicle may pass through the one or more monitored zones 290 causing the at least one controller 230 to illuminate the one or more edge lights 200. The at least one controller 230 may extinguish the one or more edge lights 200 10 minutes after they were illuminated, giving the person plenty of time to enter their vehicle and back out of the driveway 900 using the one or more edge lights 200 to guide them.

In some embodiments, the at least one controller 230 and the one or more sensors 240 may be packaged into a common enclosure. In some embodiments, the at least one controller 230, the one or more sensors 240, or both may be packaged with motion-sensing security lighting and may share functional elements with the motion-sensing security lighting. As a non-limiting example, an individual sensor 242 may be used to activate both the one or more edge lights 200 and the motion-sensing security lighting. In some embodiments, the individual sensor 242, an individual controller 232, or both may comprise one or more operator controls 238. The one or more operator controls 238 may establish operational parameters of the invention 100 such as the duration of illumination 224. As non-limiting examples, the one or more operator controls 238 may determine the sensitivity level of the individual sensor 242, the time duration that the one or more edge lights 200 stay on once energized, and a timeframe for operating the one or more edge lights 200, such as during the 6 hours after dusk.

The one or more sensors 240 and the one or more edge lights 200 may be electrically coupled via wiring 250. Specifically, the wiring 250 may comprise a power cable 252, a lighting cable 254, one or more sensor cables 256, or combinations thereof. The power cable 252 may be electrically coupled to a building electrical panel to supply power to the at least one controller 230. The lighting cable 254 may be electrically coupled to the first power connection 216 of the one or more edge lights 200. The one or more sensor cables 256 may couple the one or more sensors 240 to the at least one controller 230. The one or more sensor cables 256 may share sensor inputs between multiple controllers such that all of the controllers in an interconnected system may be aware of the activity sensed by any of the individual sensors 242. The activity in front of any one of the one or more sensors 240 may activate all of the one or more edge lights 200. The power cable 252, the lighting cable 254, and the one or more sensor cables 256 may exist as separate cables or may be distinct sets of wires within one or more common cables.

In some embodiments, the one or more edge lights 200 may be installed above one or more light supports 260 to improve the appearance of the one or more edge lights 200. Specifically, because the one or more edge lights 200 are flexible they may appear to be undulating where different portions of the one or more edge lights 200 are set deeper into the ground than adjacent portions of the one or more edge lights 200. The one or more light supports 260 may be semi-rigid footings that may be placed adjacent to the driveway 900 at a depth lower than the one or more edge lights 200 and the one or more edge lights 200 may be placed on top of the one or more light supports 260. Because the one or more light supports 260 are less flexible than the one or more edge lights 200, the one or more light supports 260 may prevent the undulations. Because the one or more light supports 260 are semi-rigid, they may flex if the vehicle drives over the one or more edge lights 200 to absorb the weight of the vehicle and may return to their original shape when the vehicle is no longer on the one or more edge lights 200.

A plurality of stakes 280 may retain the one or more edge lights 200 in place alongside the driveway 900. The plurality of stakes 280 may be driven into the ground adjacent to the one or more edge lights 200 such that heads 282 of the plurality of stakes 280 wrap over the top of the one or more edge lights 200 and shafts 284 of the plurality of stakes 280 are buried in the ground. The shape of the heads 282 of the plurality of stakes 280 may conform to the shape of the lights to minimize the profile of the plurality of stakes 280. The plurality of stakes 280 may be operable to hold the one or more edge lights 200 only or to hold the one or more edge lights 200 and the one or more light supports 260 together.
