Definitions

  • the present invention relates to lighting and in particular to hazard lighting for use on, for example, motorways.
  • the present invention seeks to provide a hazard lighting apparatus.
  • the present invention provides a hazard lighting apparatus comprising:
  • sensing means for monitoring the position or proximity or movement of a vehicle and generating a signal in response thereto;
  • control circuit for monitoring said signal and energising said light source in response to said signal indicating a vehicle moving at less than a preselected speed or drawing to a stop within a predetermined range of said sensing means.
  • the light source, power supply means, proximity sensing means and control circuit are all contained within a housing which is conveniently adapted to be mounted on a support pillar or post.
  • the sensing means may be of any suitable type and may use any suitable type of electromagnetic radiation for sensing.
  • the sensing means comprises an infrared sensor which detects the presence or movement of a vehicle within a predetermined range and generates a signal which is representative of the movement, the position or the proximity of the vehicle. More preferably, the sensing range of the sensor is adjustable.
  • the signal generated by the sensing means may be analogue or digital.
  • its amplitude or frequency may vary in dependence on the sensed movement or position/proximity of the vehicle.
  • the frequency or marlcspace ratio or amplitude or a combination of these may vary in response to the movement, proximity or position of the sensed vehicle.
  • Figure 1 is a perspective view of a preferred form of hazard lighting apparatus according to the present invention.
  • FIG. 2 is a block circuit diagram of the circuitry for the apparatus of Figure 1;
  • Figure 3 illustrates an alternative method of operation of a hazard lighting apparatus according to the invention.
  • the apparatus has a housing which is generally indicated at 12 and which has end portions 14, 16 and a centre portion 18.
  • the housing is generally rectangular in cross-section although any suitable cross-section may be used.
  • the particular form of apparatus shown in Figure 1 is of rectangular cross-section because it is intended to fit onto a marker post adjacent a motorway hard shoulder which marker posts are all generally of rectangular cross-section.
  • the lower end portion 14 of the housing has a hollow base which is intended to fit over the top of a marker post 20.
  • the portion 14 contains a proximity sensor 22. This is responsive to the movement, proximity or position of a vehicle sensed through a window 24 and generates a signal which is representative thereof.
  • the proximity sensor comprises an infra-red (IR) transmitter which is arranged to transmit a train of IR pulses at a predetermined rate. These pulses are reflected by any vehicle within the predetermined range and are received by an IR receiver within the housing. Since the pulse rate of the transmitter is known, the speed of the vehicle can be estimated by calculating the number of pulses received and dividing it by the pulse rate.
  • IR infra-red
  • the middle portion 18 of the apparatus contains a low voltage, halogen warning light 30 which can be seen, when activated, through a coloured screen or lens, typically amber or red.
  • the apparatus also contains a power supply 26 for the light 30 in the form of a rechargeable battery which is charged by means of solar panels 28 provided in the upper housing portion 16. This is particularly useful in areas of high sunshine.
  • a control circuit 32 is also provided to control energising of the light 30 in response to the signal from the proximity sensor 22.
  • the control circuit 32 is programmed to de-energise the light 30 after a preset time interval.
  • the control circuit 32 energises the light 30.
  • the proximity sensor 22 is calibrated such that it is only activated if the vehicle passes the sensor while on the motorway hard shoulder.
  • the control circuit is programmed to energise the light 30 when the proximity sensor 22 generates a signal that indicates that the vehicle speed is below a certain level (for example, less than 1 Omph) or reduces to 0 within the range of the proximity sensor, indicating that the vehicle has stopped.
  • each apparatus consists of a housing 50, for example similar to that described above, and a separate sensor unit 52.
  • Each housing 50 is mounted on a conventional marker pillar or post as before while the sensor unit 52 is mounted in the road surface at the boundary between the hard shoulder and the first lane of the motorway. Since the marker posts, and therefore the housings 50, are spaced approximately 100m apart, each sensor unit 52 is conveniently positioned approximately midway between each post 50.
  • the transmitter in the housing 50 transmits a signal, for example an infrared signal, which is received by the sensor unit 52.
  • the sensor unit responds by sending a return signal to the receiver in the housing 50.
  • the light in the housing remains deactivated. However, if this communication is disrupted, for example by a vehicle 54 moving between the housing and the sensor, then the light in the housing is activated. Since, in most cases, any vehicle entering the hard shoulder of the motorway will disrupt communication between several of the apparatus before coming to a halt, several lights will be activated "upstream" of the stationary vehicle to provide advance warning to oncoming traffic.
  • the sensor unit 52 transmits a continuous signal to the receiver in the housing 50. No transmitter is required in the housing 50. While the receiver in the housing continues to receive the signal from the sensor unit 52, the light in the housing is deactivated. However, if the signal is disrupted, for example by a vehicle 54 moving between the sensor unit 52 and the housing, the light is activated. It can be seen that by positioning a sensor unit approximately midway between the housings 50, only one sensor unit 52 is required for two housings. Each sensor unit is preferably built into the road in a low profile similar to, for example, conventional reflective "cats eyes".
  • the hazard lighting apparatus can be used at the side of any road or carriageway to indicate a temporary hazard such as a stopped vehicle. Since the light 30 is not de-energised by the control circuit 32 for a predetermined interval, a vehicle moving slowly down the hard shoulder of a carriageway will trigger a number of the devices which will remain illuminated for that predetermined interval. Thus, the lights of several devices may be energised upstream of the stationary vehicle giving advance warning to oncoming vehicles of the hazard ahead.
  • the apparatus may include a radio transmitter or the like which transmits a signal to the authorities, for example the police, when the apparatus is activated. In this manner, the authorities will be alerted to the area if a vehicle breaks down nearby.
  • the apparatus could be linked by means of the transmitter to the cameras often located along motorways, for example, on bridges spanning the motorway.
  • the radio signal generated by the transmitter could be used to allow such cameras to be trained on the location of the broken down vehicle to enable the police to visually assess the situation.
  • the apparatus could include a radio receiver or the like for receiving a remote signal which could be used to deactivate the apparatus once the vehicle has moved off.
  • the apparatus may include a reset button which is pressed manually either by the authorities or by the driver of the vehicle to deactivate the apparatus once the vehicle has or is about to move off.
  • the apparatus may also include sensors which are in addition to or combined with the existing sensors for monitoring the speed of a passing vehicle.
  • the sensor can be used to provide information to the control circuit which determines whether the vehicle is accelerating or decelerating. If the sensors indicate that the vehicle is accelerating then the control circuit does not energise the light 30 since it is assumed that the vehicle is rejoining the carriage way.
  • control circuit can energise the lamp as previously described.
  • the apparatus may be powered by a mains supply to supplement or replace the rechargeable cell.
  • the light 30 may comprise a number of LED' s or the like, arranged horizontally in a L- shape, which are supplied with sequential pulses to provide the impression of a moving or rotating light.
  • the control circuit may be programmed to de-energise the light 30 after a preset time interval such that when a vehicle passes the hazard lighting apparatus, if the movement of the vehicle has triggered the light 30 the light is extinguished once the vehicle has passed outside the range of the sensor.
